Answer:

He started with 37 CDs

Step-by-step explanation:

Variable: Let x be the number of CDs he got at the start

Equation: (x + 7) /2 = 22

x + 7 = 44

x = 37

Check: (37+7) /2 = 22

Answer:

4 times

Explanation:

tc = 15×π = 47.12.. in

bc = 2×30×π = 188.49.. in

bc = 188.5/47.12 = 4 times

Answer:

844 in.²

Step-by-step explanation:

Find the area of all the sides, and add them up

(20 x 7.4) x 2 = 296

(20 x 10) x 2 = 400

(10 x 7.4) x 2 = 148

296 + 400 + 148 = 844 in.²

Answer:

he got 80 percent correct

I don't know what you mean by equation 1. I assume you mean x + y = 7 is equation 1.

If so, solve for y as step 1.

x + y = 7

y = - x + 7

The y-intercept is 7.

Your directions do not say to solve the system of equations.

If you need to solve by graphing, use DESMOS or your graphing calculator. The solution of the system of equations is the point on the graph where the two equations meet or touch each other.

Answer: -0.67, 0.22, -0.074

Step-by-step explanation:

This is a geometric sequence because it has a common ratio. The common ratio is divide by -3.

18 / -6 = -3

-6 / 2 = -3

Therefore, we'd continue that ratio.

2 / -3 = -0.67

-0.67 / -3 = 0.22

0.22 / -3 = -0.074

It may ask you to write that in fraction form^^

In that case, 2/-3, then 2/-3 / -3, etc etc. :)

Divide by -3

Answer:

Scale factor = [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Formula for the dilation to be used,

Scale factor = [tex]\frac{\text{Dimension of the image}}{\text{Dimension of the original}}[/tex]

                    = [tex]\frac{A'B'}{AB}[/tex]

                    = [tex]\frac{1}{4}[/tex]

Therefore, scale factor by which quadrilateral ABCD has been dilated to form image quadrilateral A'B'C'D' is [tex]\frac{1}{4}[/tex].

Answer:

D' = (5, 2)

Step-by-step explanation:

Try to join D and the origin using a line. Counterclockwise means in an opposite direction of rotation of the clock hands. So draw another line towards the right which is perpendicular to the previous line to fine the answer. Remember the length of the lines should be equal.

Answer:

11x17

Step-by-step explanation:

The numbers that multiply to give 187 are 11 and 17.

Given is to multiply two numbers to give 187.

The numbers that multiply to give 187 are -

11 x 17

11 x (10 + 7)

(11 x 10) + (11 x 7)

110 + 77

187

Therefore, numbers that multiply to give 187 are 11 and 17.

Answer:

[tex]f(x) = 4\times (3)^{x}[/tex].

Step-by-step explanation:

Exponential functions are in the form [tex]f(x) = a\, \left(b^{x}\right)[/tex],  where [tex]a[/tex] and [tex]b[/tex] are constants with [tex]b > 0[/tex].

In this question, the function should satisfy that [tex]f(2) = 36[/tex] and [tex]f(3) = 108[/tex]. Hence, constants [tex]a[/tex] and [tex]b[/tex] should ensure that:

[tex]a \cdot b^2 = f(2) = 36[/tex], and

[tex]a \cdot b^3 = 108[/tex].

Rewrite the left-hand side of the second equation: [tex]a \cdot b^{3} = a \cdot b^2 \cdot b[/tex].

Substitute the first equation [tex]a \cdot b^{2} = 36[/tex] into the second:

[tex]a \cdot b^2 \cdot b = 108[/tex].

[tex]36\, b = 108[/tex].

[tex]\displaystyle b = \frac{108}{36} = 3[/tex].

Substitute [tex]b = 3[/tex] into either equation (for example, the first equation) and solve for [tex]a[/tex]:

[tex]a \cdot 3^2 = 36[/tex].

[tex]a = 4[/tex].

Hence, the exponential function [tex]f(x) = a\cdot b^{x} = 4 \times (3)^{x}[/tex] should satisfy the requirements of this question.

Answer:

960

Step-by-step explanation:

You have to figure out what 1/4th of 640 is, which is 160.

It says that number is 1/6th of boys, so you multiply by the inverse.

160x6 = 960

well since all of the girls = 4/6ths of the boys that would mean 24/24girls=16/24boys  

16/24 is 66.666666666667% of 24/24

66.666666666667% of 640 is426.666666667 but in my head i would round up so:

Approximately

427 boys and 213 girls.
