Answer:

HOPE THAT WAS TRUE

Step-by-step explanation:

[tex] - 3 + \sqrt{m + 59} = m \\ \sqrt{m + 59} = m + 3 \\ {(m + 59)}^{ \frac{1}{2} } = m + 3 \\ \frac{1}{2} log(m + 59) = log(m + 3) \\ 0.5 log(m) + 0.5 log(59) = log(m)+log(3) \\ 0.5 log(m) = 0.5 log(59) - log(3) \\ [/tex]

[tex]0.5 log(m) = 0.885 - 0.477 \\ 0.5 log(m) = 0.408 \\ log(m) = 0.816[/tex]

[tex]m = {10}^{0.816} = 6.556[/tex]

Answer:

Blue

Step-by-step explanation:

First, we need to find the LCD (Least common denominator)

Rewriting input as fractions if necessary:

1/10, 1/4, 1/5

For the denominators (10, 4, 5) the least common multiple (LCM) is 20.

Therefore, the least common denominator (LCD) is 20.

Now, we convert:

Red Marbles: 1/10 = 2/20

Blue Marbles: 1/4 = 5/20

Yellow Marbles: 1/5 = 4/20

As we can see, blue has the most. Now we have our answer! Good luck!

B

Explanation:

the wheels are getting warmer so it would have to be thermal energy, hope this helps :)

Gravitational potential energy is transformed into motion energy ,kinetic energy and thermal energy.

We know that Gravitational potential energy is the potential energy with respect to the gravitational force. To possess gravitational potential energy, the object to be placed in a position in the gravitational field.

Potential energy of body is the energy generated by virtue of the position of the body. Whereas kinetic energy is generated by virtue of its movement.

Potential energy and kinetic energy together called as mechanical energy. The potential energy is mathematically expressed as;

p = mgh.

Here, g s gravity, h is height and m is the mass.

The gravitational potential energy can be arised in an object due the position in gravitational field. That changes with the change in position and change in height from the ground.

Hence Gravitational potential energy is transformed into motion energy (kinetic energy) and thermal energy.

Answer:

a. x = 14 (see explanation)

b. the arrows along the lines

Step-by-step explanation:

The relationship of these two expressions is Same Side, which means their sum is 180.

plugging in

108 + 4x + 16 = 180 | Given

124 + 4x = 180 | Add the numbers

4x = 56 | Subtract 124 from both sides

x = 14 | Divide both sides by 4

Answer:

The length of the rectangle is 28 inches.

Step-by-step explanation:

We have that the width (W) of a rectangle is half of the length (L) of the rectangle:

[tex] W = \frac{1}{2}L [/tex]  (1)

Also, the perimeter is 84 inches:

[tex] P = 2W + 2L = 84 in [/tex]   (2)

By entering equation (1) into equation (2) we have:

[tex]2(\frac{1}{2}L) + 2L = 84 in[/tex]

[tex] L = \frac{84}{3} = 28 in [/tex]

Therefore, the length of the rectangle is 28 inches.

Answer:

Around 72.8 inches

Step-by-step explanation:

We are given the infomation that Chris is 185 centimeters tall.

There are 2.54 centimeters in an inch.

185/2.54 = 72.8346 ≈ 72.8

Chris should be around 72.8 inches.

Hope this helps.

Chris should be around 72.8 inches tall.

Here, we have,

given that,

Scott is 72 inches tall and Chris is 185 centimeters tall

We are given the information that Chris is 185 centimeters tall.

now, we know that,

There are 2.54 centimeters in an inch.

Since 1 inch = 2.54 centimeters

all we need to do is to divide 185 by 2.54

i.e. 185/2.54 = 72.8346 ≈ 72.8

The answer will be 72.8.

Chris should be around 72.8 inches.

Answer:

Step-by-step explanation:

V=4/3pi(3)^3

Answer:

a) 625,000

b) 78,125 if 0 is counted as even or 40,000 if it is not.

Step-by-step explanation:

Represent the 7 digit number by abcdefg

Position          Allowable digits          Number of allowable digits

g                      1,3,5,7,9                          5

f                       0,1,2,3,4,5,6,7,8,9          10

e                      1,3,5,7,9                          5

d                      0,1,2,3,4,5,6,7,8,9          10

c                      1,3,5,7,9                          5

b                       0,1,2,3,4,5,6,7,8,9         10

a                      1,3,5,7,9                          5

This implies that the number of 7 digit numbers with odd digits in the odd positions is

5x10x5x10x5x10x5=625000  

For part b, count 0 as an even digit.  Then rule out 1,3,5,7,9 in positions b, d, and f. This leaves 5 possible digits in all 7 locations. So the answer is

5^7=78,125    

If 0 is not counted as an even digit, then the answer is

4^3+5^4=40000

Step-by-step explanation:

y = 12(x)+28

(-1,16)

y = 12(-1)+28 = 16

(5,88)

y = 12(5)+28 = 88

Answer:

We conclude that the function [tex]f(x) = 12x + 28[/tex]  works.

The graph of the function y = 12x + 28 is also attached below.

Step-by-step explanation:

Given that the line passes through the points

Let us determine the slope between (-1, 16) and (5, 88) using the slope formula

[tex]\mathrm{m}=\frac{y_2-y_1}{x_2-x_1}[/tex]

where m is the slope between (x₁, y₁) and (x₂, y₂)

In our case:

so subtituting (x₁, y₁) = (-1, 16) and (x₂, y₂) = (5, 88) in the slope formula

[tex]\mathrm{m}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{88-16}{5-\left(-1\right)}[/tex]

Refine

[tex]m=12[/tex]

Thus, the slope of the line is: m =  12

Important Tip:

The slope-intercept form of the line equation is

[tex]y = mx + b[/tex]

where m is the slope and b is the y-intercept

now substituting m = 12 and the point (-1, 16) in the slope-intercept form of the line equation

[tex]y = mx + b[/tex]

[tex]16 = 12(-1) + b[/tex]

switch the equation

[tex]12(-1) + b = 16[/tex]

[tex]-12 + b = 16[/tex]

Add 12 to both sides

[tex]-12+b+12=16+12[/tex]

Simplify

[tex]b=28[/tex]

Thus, the y-intercept of the line is: b = 28

now substituting m = 12 and b = 28 in the slope-intercept form of the line equation

[tex]y = mx + b[/tex]

[tex]y = 12x + 28[/tex]

Thus the equation of the line is:

[tex]y = 12x + 28[/tex]

or

[tex]f(x) = 12x + 28[/tex]        ∵ [tex]y = f(x)[/tex]

Hence, we conclude that the function [tex]f(x) = 12x + 28[/tex]  works.

The graph of the function y = 12x + 28 is also attached below.

Answer:

(1, 5 )

Step-by-step explanation:

Given the 2 equations

9x + 3y = 24 → (1)

10x - 2y = 0 → (2)

Multiplying (1) by 2 and (2) by 3 and adding the result will eliminate the y- term

18x + 6y = 48 → (3)

30x - 6y = 0 → (4)

Add (3) and (4) term by term to eliminate y

48x + 0 = 48

48x = 48 ( divide both sides by 48 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for y

Substituting into (1)

9(1) + 3y = 24

9 + 3y = 24 ( subtract 9 from both sides )

3y = 15 ( divide both sides by 3 )

y = 5

solution is (1, 5 )
