Answer:

5/2

Step-by-step explanation:

The scale factor for linear measures, such as perimeter, is the square root of the scale factor for areas. The ratio of larger area to smaller is ...

... 75/12 = 25/4

so the ratio of the larger perimeter to the smaller is ...

... √(25/4) = 5/2

Answer: does the printer come with a starter pack of ink? how many ink cartridges does it take? A standard printer takes pink, blue, black, and yellow.  

Step-by-step explanation:

1) $100 for printer

2) $25 for each cartridge

total cost if take 4 cartridges:

$200

Answer:

25*x+100

Step-by-step explanation: You do 25 multiplied by the number of cartridges (x) and then add 100 for the cost of the printer. For example, if you buy 5 cartridges, it would be, 25*5+100 and then it would equal 225 or 225 dollars for the overall cost of the printer.

Answer:

2+√3

Step-by-step explanation:

We know that roots with square roots come in pairs

so if we have a+ sqrt(b), we will also have a - sqrt(b)

Since one of the roots is 2 -sqrt(3), it must have another root of 2+ sqrt(3)

The conjugate of the root (2-√3) for a polynomial with integer coefficients is (2+√3), which must also be a root of the polynomial.

If (2-√3) is a root of a polynomial with integer coefficients, then by the Conjugate Root Theorem (which is a consequence of the Complex Conjugate Root Theorem), if the polynomial has real coefficients and a non-real root, then its complex conjugate must also be a root. However, since √3 is a real number and our expression involves only real numbers, in this context, we look for the conjugate in terms of radicals. Thus, the conjugate of (2-√3) would be (2+√3), which must also be a root of the polynomial.

The other options given, such as 2√3, √3-2, and 3-√2, do not satisfy the criteria of being the conjugate of (2-√3). They might be roots of some polynomial, but without the constraint of integer coefficients or known conjugate pairs, we cannot confirm that.

Answer:

$13

Step-by-step explanation:

$26,555 ÷ 36 = 737.6388889 ≈ $738 per month

36 × 738 = $26,568

= $13

Answer:

$13 will be overpaid after 36 months if payments are rounded of to nearest whole number dollar.

Step-by-step explanation:

We are given the following in the question:

Total cost of car = $26,555

Number of equal installments made = 36

Payment of 1 installment =

[tex]\displaystyle\frac{\text{Toatl cost}}{\text{Number of installments}} = \frac{26555}{36} = 737.6389\$[/tex]

Rounding of to nearest whole number, payment of one installment =  $738

Value of 36 installments of $738 each =

[tex]36\times 738 = 26568\$[/tex]

Money overpaid after 6 months =

[tex]26568 - 26555 = 13\$[/tex]

Thus, $13 will be overpaid after 36 months if payments are rounded of to nearest whole number dollar.

Answer:

–x^3 + 5x^2 – 8x + 1

Step-by-step explanation:

You can observe that expanding f(2-x) will give you a sum that includes (2-x)³, so will have a -x³ term. This narrows the choices to one of the first two.

If x=0, then you have ...

... f(2) = 2^3 -2^2 -3 = 8 - 4 - 3 = 1 . . . . corresponds to the first selection

Answer:

71.79 degrees

Step-by-step explanation:

The cosine is (adjacent side to angle) / (hypotenuse)

so the cosine of x = 5/16

to get x you multiply cosine by its inverse

(cos^-1 x)(cos x) = (cos^-1 x)(5/16)

= 71.79 degrees

He will be able to bounce the ball 125 times

Answer:

The ball will bounce 125 times

Step-by-step explanation:

We can use ratio's to solve this problem.  I will put how many times the basketball is bounced on top and how many seconds on the bottom.

25 times         x times

-------------   = ----------------

30 seconds    150 seconds

Using cross products

25 * 150 = 30 * x

Divide each side by 30

25*150/30 =30*x/30

25 * 5 = x

125 =x

Answer:

option no D

Step-by-step explanation:

AS it given that it is a random generator

so it will generate random integers between 1 and 3

so

possible sample space = {1,2,3}

Total no of out comes = 3

Estimated probability that 3 will occur will be obtained by dividing total no of outcomes with total no of possible events to occur

as the occurrence of event is only 1

so

Estimated probability = 1 /3 = 0.33333

Now

The experiment is performed

total outcomes = 14

Total no of like able events that 3 occurred = 4

Actual probability = 4 / 14

                             = 0.2857

Difference between actual and estimated probability is = 0.3333-0.2857

                                                                                            =0.0421

                                                                                           ≅0.04

which is option D

Final answer:

The actual probability of a 3 being generated is 1/3, and the estimated probability from the given sequence is 4/14. The difference between the two probabilities is roughly 0.05, which corresponds to answer choice C.

Explanation:

The question refers to the probability of a random generator selecting the number 3 from a set of integers ranging from 1 to 3, where each number has an equal chance of being selected. The actual probability of the random generator selecting a 3 is 1/3, as there are three possible outcomes and each is equally likely. To find the estimated probability, we can look at the frequency of the number 3 in the provided set of generated numbers: (1 2 3 3 3 2 2 1 1 1 2 3 1 1). In this set, there are 4 occurrences of the number 3 out of 14 total numbers. Therefore, the estimated probability is 4/14 or approximately 0.2857. The difference between the estimated and actual probabilities is 0.3333 (actual) - 0.2857 (estimated) = 0.0476. When rounded to two decimal places, the difference is approximately 0.05. Thus, the correct answer to the question would be C. 0.05.

Answer:

See attached picture

Step-by-step explanation:

The ratios of sides in a 30°-60°-90° triangle are ...

... 1 : √3 : 2

Multiplying these ratio units by 3 inches, we get the side lengths to be ...

... 3 in : 3√3 in : 6 in

Thus, a = 3 in; b = 3√3 in.

_____

Alternate solution

Or, you can work from your memorized values of the trig functions of 30° and 60°.

... sin(30°) = a/(6 in) = 1/2 . . ⇒ . . a = (1/2)·6 in = 3 in

... cos(30°) = b/(6 in) = (√3)/2 . . ⇒ . . b = (√3)/2·6 in = 3√3 in

Answer:

f(x) and g(x) have the same x-intercepts (is not true)

Step-by-step explanation:

g(x) is a reflection across the y-axis and a horizontal compression of f(x). In general those transformations will move the x-intercepts. (The y-intercept and the number of x-intercepts will remain unchanged.)

_____

Comment on the question/answer

f(x) = x^3 is a 3rd degree polynomial. When transformed to g(x) = -8x^2, its only x-intercept (x=0) remains the same. The answer above will not apply in any instance where the only x-intercept is on the line of reflection. (The question is flawed in that it does not make any exception for such functions.)

7 months

After Carter makes his $500 payment, the balance on the loan is -1596.37. We want to find the number of months (m) such that ...

... -1596.37 +250m ≥ 0

... m ≥ 1596.37/250 . . . . add 1596.37, divide by the coefficient of m

... m ≥ 6.4

The least number of months that is more than 6.4 is 7 months.

_____

Comment on this answer

Carter's loan balance may also be affected by interest charged on the loan amount. We don't expect those charges to be so high as to require an additional month's payment.

[tex]\frac{x}{8} + 19 = 30[/tex] - subtract 19 from both sides

[tex]\frac{x}{8} = 11[/tex] - multiply both sides by 8

In this equation, x = 88.

Answer:

26 most years; 27 some years

Step-by-step explanation:

1 day out of 14 is 1/14 of the number of days in a year.

The number of days in a year depends on the year or years you're talking about. In all cases, there are not an integer number of weeks in a year, so days are left over. 365/14 = 26 1/14.

For example, if you're concerned with every other Monday, most years, there will be 26 of them, but every few years there will be 27. Over a period of 800 years, there will be exactly 71 years with 27 days of interest instead of 26. 800 is not divisible by 71, so the spacing will be uneven.

Answer:

96°

Step-by-step explanation:

ΔKLM is isosceles, so base angle KML will be half the supplement of ∠MLK, or ...

.... ∠KML = (180° -48°)/2 = 66°

ΔKJM is also isosceles, so base angle JMK will be the same measure as ∠JKM, 30°.

∠JML = ∠JMK + ∠KML = 30° +66°

∠JML = 96°

Answer:

The correct answer is 5.34

Step-by-step explanation:

you can double check this by multiplying .6 and 8.9

Answer:

x = 5.34

Step-by-step explanation:

x/ .6 = 8.9

We want to solve for x, which means we want x by itself.

Multiply each side by .6

x/ .6  * .6= 8.9 * .6

x = 5.34

Answer:

[tex]24p[/tex]

Step-by-step explanation:

There's a very useful pattern in factoring and multiplying binomials called a difference of squares, and it looks like this:

[tex](x+y)(x-y)=x^2-y^2[/tex]

We can use this difference of squares to factor the expression we've been given, setting [tex]x=2p+3[/tex] and [tex]y=2p-3[/tex] to obtain the expression

[tex](2p+3)^2-(2p-3)^2=[(2p+3)+(2p-3)][(2p+3)-(2p-3)][/tex] (1)

tackling each of the multiplicands on the right:

[tex](2p+3)+(2p-3)=2p+2p+3-3=4p[/tex] (Left)

[tex](2p+3)-(2p-3)=2p-2p+3-(-3)=3+3=6[/tex] (Right)

This simplifies the expression on the right of (1) to [tex]4p\cdot6[/tex], or simply [tex]24p[/tex].

Answer:

It would be C

Here's Why:

Finding the missing value in mathematics usually involves solving an equation. The process can vary depending on whether the problem involves algebra, geometry or another mathematical principle.

In mathematics, finding the missing value typically involves solving an equation where a variable represents the unknown, or missing, value. The task requires understanding of the mathematical principle being applied. For example, if you have an equation like 2x = 10, you can solve for the missing value (x) by dividing both sides of the equation by 2, which gives x = 5. If the problem involves a geometric figure, understanding the relevant formulas for area, volume, perimeters, etc. is key.
