A recipe calls for 1/2 cup of ingredient A for every 1 2/5 cups of ingredient B. You use 4 cups of ingredient A. How many cups of ingredient B do you need?

Answers

Answer 1

Let x = number of cups of ingredient B if 2 cups of ingredient A are used. Set up a proportion: (1/2)/(1 2/5) = (2)/x. Cross multiplying we get (1/2)x = (1 2/5)(2)
(1/2)x = 14/5, so x = 28/5 = 5 3/5 cups.

Answer 2

you use 1 2/5 of B for every 1/2 A and they use 4 of A so times 1 2/5 by 8 and you get 11.2 cups of B

a vendor has learned that, by pricing pretzels at $1.50 sales will reach 91 pretzels per day. raising the price to $2.25 will cause the sales to fall to 58 pretzels per day. Let y be the number of pretzels the vendor sells at x dollars each. Write a linear equation that models the number of pretzels sold per day when the price is x dollars each

Answers

The givens can be expressed as the abscissa and ordinate of two points. The first point is (1.5, 91). The second point would then have the coordinates of (2.25, 58)
We are given with two points so we can derive the equation using the two-point form.
That is,
y – y1 = ((y2 – y1)/(x2 – x1))(x – x1)

We may choose which among our derived coordinates will be 1 and 2. Substituting to the equation,
y – 91 = ((58 – 91)/(2.25 – 1.5))(x – 1.5)
y – 91 = -44(x – 1.5)
Simplifying further,
y – 91 = -44x + 66

y = -44x + 157

Thus, the equation above gives the number of pretzels that can be sold given the price.

To model the number of pretzels sold per day as a function of the price in dollars using a linear equation, calculate the slope of the line using two known points, and then use the slope and one point to find the y-intercept. The resulting linear equation is y = -44x + 157, where y represents the number of pretzels sold and x represents the price in dollars.

To write a linear equation that models the number of pretzels sold per day when the price is x dollars each, we can start with two given points that represent the sales and price data: (1.50, 91) and (2.25, 58).

Using these points, we can first find the slope of the demand line.

The formula for slope (m) is:

m = (y2 - y1) / (x2 - x1)

Plugging in our values, we get:

m = (58 - 91) / (2.25 - 1.50) = (-33) / (0.75) = -44

The slope of the demand function is -44. This means that for each dollar increase in price, 44 fewer pretzels are sold.

Next, we use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept. To find the y-intercept, we can use one of the given points. Let's use (1.50, 91).

91 = (-44)(1.50) + b
b = 91 + 66
b = 157

The y-intercept, b, is 157. Knowing both m and b, we can now write the equation of the line:

y = -44x + 157

This equation models the number of pretzels sold, y, at a price of x dollars each.

The difference between the squares of two numbers is 7. Four times the square of the first number increased by the square of the second number is 73. By formulating this information into equations, the numbers, thus, obtained are 3 and 4 or -3 and -4.

An equation is a combination of numbers, variables, functions, mathematical operations, etc. in a meaningful way. The equation comprises two or more expressions separated by the equality sign(=), indicating the equivalency.

Let the numbers be x and y, then according to the question,

A bag contains 6 poker chips, one is red and the other 5 are blue. you and a friend take turns selecting a chip at random from the bag. the first person to get the red chip is the winner. find the probability that you win if you go first and

Answers

the probability of pulling the red chip if you go first is 1/6

first it's 1/6
second = 1/5
Third= 1/4
fourth= 1/3
Fifth = 1/2
And sixth is guaranteed

Final answer:

The probability that you win if you go first is calculated as a sum of an infinite geometric series considering the odds of drawing the red chip in the first or subsequent rounds and is found to be 1/2.

Explanation:

The probability that you win the game if you go first can be found by considering the possibilities of either drawing the red chip on your first turn or on subsequent turns after both you and your friend did not draw the red chip in the previous rounds. In the first round, you have a 1/6 chance of picking the red chip and winning immediately. If you don't draw the red chip, then your friend has a 1/5 chance of drawing it on their first turn, assuming you drew a blue chip.

If both of you fail to draw the red chip on the first turn, the situation repeats with you having another chance to win with the same odds as your first turn. Since this can go on indefinitely, the probability of you winning can be expressed as a geometric series:

P(you win) = 1/6 + (5/6)(4/5)(1/6) + (5/6)^2(4/5)^2(1/6) + ...

This series can be summed up using the formula for the sum of an infinite geometric series a/(1-r), where a is the first term of the series (1/6 in this case), and r is the common ratio ((5/6)(4/5)). The common ratio can be simplified to (4/6) or (2/3), and the sum of the series gives us the final probability. Therefore, the probability that you win the game if you go first is:

P(you win) = 1/6 / (1 - (2/3)) = 1/6 / (1/3) = 1/2.

Quadrilateral STWR is inscribed inside a circle as shown below. Write a proof showing that angles T and R are supplementary. Circle Q is shown with an inscribed quadrilateral labeled RSTW.

Answers

Consider the figure attached.

Let m(R)=α degrees and m(T)=β degrees.

1.
Angle R, is an inscribed angle, intercepting the arc WTS.
This means that the measure of the arc WTS is double the measure of the angle R,

so m(arc WTS) = 2α degrees.

2.
Similarly,

Angle T, is an inscribed angle, intercepting the arc WRS. So

m(arc WRS) = 2β degrees.

3.
m(arc WTS)+m(arc WRS)=360° since these arcs cover the whole circle.

thus

2α+2β=360°

divide by 2:

α+β=180°

this means T and R are supplementary angles.

Answer:

Step-by-step explanation:

Arc STR measures twice the measure of angle R, and arc WRS measures twice the measure of angle T.

STR = 2 x ∠R and WRS = 2 x ∠T --- This is because of the Inscribed Angle Theorem

If the measure of arcs STR and WRS are added together, the total would be 360° since a full circle is made up of 360°.

So mSTR + mWRS = 360°

Substituting the angle measures of R and T in for the arcs, the equation becomes:

2 • ∠R + 2 • ∠T = 360°

Simplifying further:

2 • [∠R + ∠T] = 360°

∠R + ∠T = 360° / 2

∠R + ∠T = 180° - This proves that opposite angles of a quadrilateral inscribed in a circle are supplementary.

martha and mary had 375 jelly beans in all. after mary ate 24 jelly beans and martha ate 1/7 of her jelly beans, they each had the same number of jelly beans left. how many jelly beans did each girl have at first?

Answers

Start by setting up two equations

Let x = number of beans with Martha
Let y = number of beans with Mary

Since total beans is 375,
x + y = 375

Mary ate 24 beans, after this she must be having x - 24 beans
Similarly after eating 1/7y beans, mary must be having y - y/7 beans
Setting them equal to each other
x - 24 = y - y/7

Solving both equations gives x = 186, y = 189

Calculate M6 for f(x)=4⋅ln(x^2) over [1,2].

Answers

In this we need to approximate definite integral by midpoint formula.
According to this formula if we have to calculate [tex] \int\limits^a_b {f(x)} \, dx [/tex]
then we will divide the interval [a,b] into n subinterval of equal width.
Δx = [tex] \frac{b-a}{n} [/tex]
So we will denote each of interval as follows
[tex][x_0 , x_1] , [x_1, x_2], ................[x_{n-1} , x_n][/tex] where [tex]x_0 = a , x_n = b[/tex]
Then for each interval we will calculate midpoint.
So we can calculate definite integral as
[tex] \int\limits^a_b {f(x)} \, dx = \triangle x f(y_1) + \triangle x f(y_2)+ ...............+ \triangle x f(y_n)[/tex]
where [tex]y_1 , y_2 , ....................y_n [/tex] are midpoint of each interval.

So in given question we need to calculate [tex]M_6[/tex] . So we will divide our interval in 6 equal parts.
Given interval is [1,2]
[tex]\triangle x = \frac{2-1}{6} = \frac{1}{6} [/tex]

So we will denote 6 interval as follows
[tex][1 , \frac{7}{6}] , [ \frac{7}{6} , \frac{8}{6} ] , [ \frac{8}{6} , \frac{9}{6} ] , [ \frac{9}{6} , \frac{10}{6} ] , [ \frac{10}{6} , \frac{11}{6} ] , [ \frac{11}{6} , 2 ] [/tex]
Now midpoint of each interval is
[tex]y_1 = \frac{1+ \frac{7}{6} }{2} = \frac{13}{12} = 1.084[/tex]
[tex]y_2 = \frac{ \frac{7}{6} + \frac{8}{6} }{2} = \frac{15}{12} = 1.25[/tex]
[tex]y_3 = \frac{ \frac{8}{6} + \frac{9}{6} }{2} = \frac{17}{12} = 1.417[/tex]
[tex]y_4 = \frac{ \frac{9}{6} + \frac{10}{6} }{2} = \frac{19}{12} = 1.584[/tex]
[tex]y_5 = \frac{ \frac{10}{6} + \frac{11}{6} }{2} = \frac{21}{12} = 1.75[/tex]
[tex]y_6 = \frac{ \frac{11}{6} + \frac{12}{6} }{2} = \frac{23}{12} = 1.917[/tex]

So [tex]M_6[/tex] for the given function is

[tex]M_6 = \triangle x [f(y_1) + f(y_2) + f(y_3) + f(y_4) + f(y_5) + f(y_6) ][/tex]
[tex]= \frac{1}{6}[0.6452+1.7851+2.7883+3.6796+4.4769+5.4243][/tex]
[tex]= \frac{1}{6} * 18.7994 = 3.1333 [/tex]
So [tex]M_6 value for function is 3.1333[/tex]

Final answer:

To calculate M6 for f(x)=4⋅ln(x^2) over [1,2], differentiate the function to find f'(x). Integrate f'(x) over the given interval to find the area under the curve. Subtract the value of the integral at the lower limit from the value at the upper limit to get M6.

A company that packages cold cuts needs to transport the packaged meat to the supermarket.it will cost $1,200 to rent a truck,and it will cost an additional $100 for every 50 pounds transported.which equation represents the transport cost for every 50 pounds if cold cuts transported? The options are
A) y=1,200-100x
B) y= 1,200+100x
C) y=1,200x +100
D) y=100x-1,200

Answers

it to calculate the cost of $100 for every 50lbs, you would use 100x

then you need to add that to the 1200

so the equation would be y = 1200+100x

B is the correct answer

A Square has sides that are the same length as the radius of a circle. If the circle has an area of 36π square units how many units long is the perimeter of the square?

Answers

ok so...... the correct answer is ......113.04

πr²= 36π or, r=6 units
now side of a square (l)=radius (r)=6
perimeter of square=4l=6×4=24 units ans

An electronic product contains 40 integrated circuits. the probability that any integrated circuit is defective is 0.01, and the integrated circuits are independent. the product operates only if there are no defective integrated circuits. what is the probability that the product operates?

Answers

Final answer:

The probability that the product operates is 0.6706 or 67.06%.

Explanation:

To find the probability that the product operates, we need to find the probability that all 40 integrated circuits are not defective. Since the probability of any integrated circuit being defective is 0.01, the probability that a circuit is not defective is 1 - 0.01 = 0.99. Since the integrated circuits are independent, we can multiply the probabilities together:

P(product operates) = (0.99)⁴⁰ = 0.6706

Therefore, the probability that the product operates is 0.6706 or 67.06%.

The points L(10,9) M(10,-5) N(-1,-5) and O(-1,9) form rectangle L M N O Which point is halfway between O and N.

A.) (-1,0)
B.) (-1,7)
C.) (-1,2)
D.) (2,-1)

Answers

Answer:

C.) (-1, 2)

Step-by-step explanation:

You can plot the points on a graph, or you can just find the midpoint:

midpoint = (O + N)/2 = ((-1, 9) +(-1, -5))/2 = (-1-1, 9-5)/2 = (-2, 4)/2

midpoint = (-1, 2)

Which graph represents the solutions to the inequality |2x − 4| less than or equal to 14?
A)number line with an open circle on negative 5, shading to the right and an open circle on 9, shading to the left
B) number line with a closed circle on negative 5, shading to the right and a closed circle on 9, shading to the left
C) number line with an open circle on negative 5, shading to the left and an open circle on 9, shading to the right
D) number line with a closed circle on negative 5, shading to the left and a closed circle on 9, shading to the right

Answers

The graph that represents the solutions to the inequality |2x − 4| less than or equal to 14 or |2x - 4| ≤ 14 is a number line with a closed circle on negative 5, shading to the right and a closed circle on 9, shading to the left. The answer is letter B. The less than or equal to symbol or '≤' represents that all integers less than or equal to 9 are all solutions to the given inequality.
