QUESTION
4. Mickey and Minnie went to a Sabres game.
They each purchased two shirts and a $17
autographed hockey puck. If Mickey and
Minnie spent a total of $214, how much was
each shirt?

Answers

Answer 1

Answer:

45

Step-by step

What do we already know about the equation?

We know that they EACH bought a hockey puck($17) and 2 shirts

Half of 214 is 107. So they had to have spent 107 separately

So we make the equation and let s represent shirts

2s + 17 = 107

    - 17            -17

2s= 90.    DIVIDE by 2

s = 45

Answer 2
I agree with Karen!!!!!

an 8 oz drink cost 2.16 an a 10 oz drink cost 2.75 which is better why

Answers

Answer:

The better one? 8 oz

Step-by-step explanation:

You might be wondering why. You divide the cost by the oz. (or like a kind of capacity measurement or like weigh) For example, 2.16/ 8 is 0.27, that means per oz it is 0.27. Then, you find it for a 10 oz that costs 2.75, that is equal to 0.275. 0.275 is more than 0.27 so a 8 oz must be better to buy.

Answer: 8 oz drink

Step-by-step explanation: In this problem, we are asked to determine which of the following drinks is a better buy.

A 8 oz drink that for $2.16 or a 10 oz drink for $2.75.

Since the drinks that we are comparing are different sizes, to determine which drink is a better buy, we first need to find the unit price of each drink which in this case is the cost per ounce of each drink.

For our first drink, since $2.16 is the cost for 8 oz, to find the cost per ounce, we divide 8 into 2.16 to get 0.27. So the 1 ounce drink has a unit price of 0.27 cents per ounce.

For our second drink, since $2.75 is the cost for 10 oz, to find the cost per ounce, we divide 10 into 2.75 to get 0.275.

Finally we want to know which drink is a better buy so we are looking for the drink with the lower unit price. Since 0.27 cents is less than 0.275 cents, the 8 oz drink has the lower unit price and is therefore the better buy.

the amount of water remaining in a fish tank is given by the equation y = 175 - 15x where y is the number of gallons of water remaining
fter x minutes,
That is the approximate time it would take to drain the fish tank?
A. 12 minutes
B. 85 minutes
C 160 minutes
D. 175 minutes
E. 190 minutes

Answers

Answer:

The correct answer is A. 12 minutes.

Step-by-step explanation:

Let's solve for y, when x = 12, as follows:

y = 175 - 15x

y = 175 - 15 * 12

y = 175 - 180

y = - 5

This result means that after 12 minutes the fish tank would be completely drained and if it's needed 5 additional gallons of water could also be drained. It's not necessary to continue making more calculation with the the other options given because this is the right answer.

The correct answer is A. 12 minutes.

What are the digits of pii?

Answers

Step-by-step explanation: Pi is an irrational number 3.14159... which rounds to 3.14.

Mathematicians found out that when you try to write down what π is, the decimal the decimal places just keep going and going. This means it's impossible to find all the digits of π.

To solve many problems involving π, you just round it off to 3.14 and it will work. However, if you include more digits, your answer will be more accurate.

The first 100 digits of pi are below.

3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679

Final answer:

Pi, a key mathematical constant, can be approximated to 3.14 but extends infinitely. Each digit after the decimal point serves a purpose in precision in calculations. Digits form numbers and range from 0 to 9, with the decimal point establishing the value of the number.

Explanation:

The digits of pi, which is a mathematical constant representing the ratio of a circle's circumference to its diameter, are numerous as pi extends infinitely beyond the decimal point. However, in most contexts, it is approximated to 3.14. These first two digits are usually sufficient for common calculations in geometry, note that pi includes many more digits in its full representation.

When it comes to number rounding, it is worth noting that each digit after the decimal point matters. In terms of importance from left to right, a digit would be replaced by a zero if the next immediate number is 5 or above; this next number then either rounds up the previous number or maintains it depending on if it's below or above 5.

Digits are the components making up a number. They range from 0 to 9 and can be put in a sequence to form a variety of numbers. The placement of the decimal point also plays a vital role in establishing the numeric value of the number.

Answers

Answer: [tex]\frac{(x+4)(x+1)}{x+2}[/tex]

Step-by-step explanation:

The area of a rectangle [tex]A[/tex] is given by the multiplication of its base [tex]b[/tex] by its height [tex]h[/tex]:

[tex]A=(b)(h)=x^{2}+5x+4[/tex] (1)

Lucas bought six packs of 25 pens each for four dollars per pack and sold each pen for $.25 how much was his profit?

Answers

Answer:

$13.50

Step-by-step explanation:

To find Lucas's profit, subtract the cost from his total gain.

Lucas bought 6 packs for $4 each.

6 * $4 = $24

His cost is $24.

In each of the 6 packs, there were 25 pens.

6 * 25 = 150 total pens

Lucas sold each pen for $0.25

150 * $0.25 = $37.50

$37.50 - $24 = $13.50

A path of a toy rocket thrown upward from the ground at a rate of 208 ft/sec is modeled by the quadratic function h(t) = -16t +208t. When will the rocket reach its maximum height? What will be the maximum height?

Answers

Answer:

The time = 6.5 seconds and the maximum height reached by the rocket = 676 feet

Step-by-step explanation:

A path of a toy rocket thrown upward from the ground at a rate of 208 ft/sec is modeled by the quadratic function h(t) = -16[tex]t^{2}[/tex] +208t.

We have to find when the rocket will reach its maximum height.

When the rocket reaches its maximum height, [tex]\frac{dh}{dt}[/tex] = 0.

h(t) = -16[tex]t^{2}[/tex] +208t

[tex]\frac{dh}{dt}[/tex] = - 32t + 208 = 0

t = 6.5 seconds

At t = 6.5 seconds it is at maximum height.

Maximum height = - 16[tex]\times (6.5^{2} ) + 208\times 6.5[/tex]

                            = 676 feet

Answer:

Time taken = 6.5s . Maximum height = 676 feet.

Step-by-step explanation:

To find the maxima of height function use differentiation ie, h(t) will be maximum when [tex]\frac{dh(t)}{dt} = 0[/tex] .

[tex]h(t) = -16t^{2} + 208t\\\frac{dh(t)}{dt}= -32t + 208[/tex]

[tex]\frac{dh(t)}{dt} = 0[/tex] ⇒ -32t +208 = 0

32t = 208

[tex]t = \frac{208}{32} = 6.5[/tex]

For maximum height put t = 6.5  in h(t),

Maximum height = -16×6.5×6.5  + 208×6.5

=676 feet.

In the U.S. there was one marriage every 13.4 seconds in 2000. Construct a linear function where the domain is hours and the range is the number of marriages. Round to the nearest whole number.

Answers

Final answer:

To construct the linear function for the number of marriages per hour in the U.S., you calculate the number of marriages in one hour by dividing 3600 seconds by 13.4 seconds and rounding to the nearest whole number. The linear function is y = 269x, with the domain being non-negative hours (x) and the range being whole number marriages (y).

Explanation:

To construct a linear function representing the number of marriages in the U.S. as a function of time given in hours, we can start by determining how many marriages occur every second. Since there was one marriage every 13.4 seconds in 2000, we first convert an hour to seconds, which is 3600 seconds per hour. Then we divide 3600 by 13.4 to find how many marriages occur in an hour. This gives us approximately 268.66, which we can round to the nearest whole number, yielding about 269 marriages per hour.

Let's denote the number of hours as x and the number of marriages as y. Thus, the linear function is y = 269x. The domain of this function is the number of hours, which we can assume to be all non-negative real numbers (x >= 0), representing the continuous passage of time. The range of the function is the number of marriages, which also comprises non-negative whole numbers, as you wouldn't have a fraction of a marriage.

An ice cream shop offers two ice cream cones. the waffle cone holds 12 ounces and is 5 inches tall. the sugar cone also holds 12 ounces and is 8 inches tall. Which cone has a larger radius?

Answers

Final answer:

The waffle cone has a larger radius compared to the sugar cone.

Explanation:

The radius of a cone can be found using the formula:

radius = volume / height / pi

Both cones have the same volume of 12 ounces, so we can use this formula to compare their radii:

For the waffle cone: radius = 12 / 5 / pi = 0.766

For the sugar cone: radius = 12 / 8 / pi = 0.477

Therefore, the waffle cone has a larger radius compared to the sugar cone.

https://brainly.com/question/31756016

#SPJ3

The waffle cone has a larger radius of approximately 2.03 inches compared to the sugar cone's radius of approximately 1.61 inches.

To determine which cone has a larger radius, we need to calculate the radius of each cone using the volume formula for a cone. Since both cones hold the same volume (12 ounces), we'll convert this to cubic inches (since 1 ounce is approximately 1.8 cubic inches, 12 ounces is roughly 21.6 cubic inches).

The volume formula for a cone is:

V = (1/3)πr²h

Where V is the volume, r is the radius, and h is the height.

Waffle Cone:

Volume (V) = 21.6 cubic inches
Height (h) = 5 inches

Therefore, we have:

21.6 = (1/3)πr²(5)

Solving for r, we get:

21.6 = (5/3)πr²
r² = 21.6 / ((5/3)π)
r² = 12.97 / π
r ≈ sqrt(4.13)
r ≈ 2.03 inches

Sugar Cone:

Volume (V) = 21.6 cubic inches
Height (h) = 8 inches

Therefore, we have:

21.6 = (1/3)πr²(8)

Solving for r, we get:

21.6 = (8/3)πr²
r² = 21.6 / ((8/3)π)
r² = 8.1 / π
r ≈ sqrt(2.58)
r ≈ 1.61 inches

Comparing the two radii, the waffle cone has a larger radius of approximately 2.03 inches, while the sugar cone has a smaller radius of approximately 1.61 inches.

Has an x-intercept of (4,0) and a y- intercept of (0,-2)

Write the equation in standard form, slope intercept form and point slope form

Answers

Just to be different we'll start with intercept intercept form which says the line through x intercept (a,0) and y intercept (0,b) is

[tex]\dfrac x a + \dfrac y b = 1[/tex]

Through (4,0) and (0,-2) that's

[tex]\dfrac{x}{4} + \dfrac{y}{-2} = 1[/tex]

Multiply through by the common denominator of 4 for standard form:

x - 2y = 4

For slope intercept form we solve for y

-2 y = -x + 4

y = (1/2) x - 2

We see our slope is (1/2) and we go through (4,0) so point slope form is

y - 0 = (1/2)(x - 4)

y = (1/2)(x-4)

The equation is y = 1/2(x - 4), and converting this to standard form results in x - 2y = 4.

To find the equation of the line that passes through the x-intercept (4,0) and y-intercept (0,-2), we need to derive its slope and then write the equation in different forms:

Step 1: Calculate the Slope

The slope (m) is given by
m = (y2 - y1) / (x2 - x1).
Using the given intercepts (4,0) and (0,-2):

m = (0 - (-2)) / (4 - 0) = 2 / 4 = 1/2

Step 2: Slope-Intercept Form

The slope-intercept form is
y = mx + b, where m is the slope and b is the y-intercept. We know that the y-intercept, b, is -2.

Thus, the equation in slope-intercept form is:

y = 1/2 x - 2

Step 3: Point-Slope Form

The point-slope form is given by
y - y1 = m(x - x1).
Using the point (4,0):

y - 0 = 1/2(x - 4)

Which simplifies to:

y = 1/2(x - 4)

Step 4: Standard Form

Standard form is
Ax + By = C. To convert our slope-intercept form (y = 1/2 x - 2) to standard form, we follow these steps:

Multiply both sides by 2 to eliminate the fraction:
2y = x - 4

Rearrange to get integer coefficients on the left side:
x - 2y = 4

Thus, the equation in standard form is: x - 2y = 4

Final answer:

Equivalent fractions for 3/8 could be 6/16 or 12/32, and for 1/4, they could be 2/8 or 4/16, achieved by multiplying both the numerator and denominator by the same number.

Explanation:

The student asked which pairs of fractions are equivalent to 3/8 pound of Swiss cheese and 1/4 pound of American cheese. To find equivalent fractions, we multiply or divide both the numerator and the denominator of the fraction by the same number. For example, if we multiply the numerator and denominator of 3/8 by 2, we get 6/16, which is equivalent to 3/8. Likewise, if we multiply the numerator and denominator of 1/4 by 2, we get 2/8 which is equivalent to 1/4. Another pair of equivalent fractions can be found by multiplying 3/8 and 1/4 each by 4, resulting in 12/32 and 4/16 respectively.

Which expressions are equivalent

Answers

Answer:

5 cubed, 5 (6-3), and 5 to the power of 6 divided by 5 cubed.

Answer:

5^(6-3), 5^6/5^3, 5^3 or the 1st and 3rd on the top row and the 2nd on the bottom row

Step-by-step explanation:

So, how exponent rules work is if x to the power of any number is multiplied by x to the power of any number, you add the exponents. For example, 5^6 multiplied by 5^-3 is 6-3 which is 3, so the answer is 5^3. If you are dividing, lets say you have 5^6/5^3, you subtract. It would be 6-3, and the answer would be 5^3. When you have x to the power of a number, and you have that in parenthesis, and there is an exponent on the outside, only then do you multiply the exponents, and you cannot multiply exponents if there are more than one term in the parenthesis. For example, (x^5)^5 = x^25 because 5x5 = 25. But, if you have (x-5)^2 you cannot multiply the 2 out on both terms, you have to instead use FOIL. Using these rules, you can find that each of the answers above is equal to the answer of the first equation, 5^3.

5^(6) x 5^(-3) = 5^(6-3) = 5^(3)

5^6/5^3 = 5^(6-3) = 5^(3)

5^3 = 5^3

                                                    Question # 4

Answer:

Total number of cameras left to bid on = 3/5

Step-by-step Explanation:

To determine:

What fraction of the total number of cameras is left to bid on?

Solution Steps:

Total number of antique cameras contributed by a local shop = 10The number of cameras accepted for bids = 4

Total number of cameras left to bid on = 10/10 - 4/10

                                                                  = 6/10

                                                                   = 3/5   ∵ As 6/10 = 3/5

Hence, total number of cameras left to bid on = 3/5

                                               Question # 5

Answer:

The remaining portion of tickets = 17/100

Step-by-step Explanation:

To determine:

What portion of the tickets remain?

Solution Steps:

The total number of tickets = 100The number of tickets that were sold in first week = 83

The remaining portion of tickets = 100/100 - 83/100

                                                       = 17/100

Hence, the remaining portion of tickets = 17/100

As in the text, we are given a sequence of numbers a1, . . . , an, which we assume are all distinct, and we define an inversion to be a pair i < j such that aj < ai . We motivated the problem of counting inversions as a good measure of how different two orderings are. However, one might feel that this measure is too sensitive. Lets call a pair a significant inversion if i < j and 2aj < ai . (a) Describe a O(n log n) algorithm to count the number of significant inversions between two orderings. Make clear how is it that your algorithm would achieve the given O(n log n) execution time bound.
