Answer:

$127.50

Step-by-step explanation:

$45/3 = $15 per hour

$15 x 8.5 = $127.50

Answer:

127.50 dollars

Step-by-step explanation:

He makes $15/an hour because $45/3 = $15. 15 x 8.5 = $127.50.

Answer:

2^5/3 = (2^5)^1/3 = 32^1/3 = ∛32

Step-by-step explanation:

Answer:

x is equal to ± 1/2

Step-by-step explanation:

To find x, we simply need to take the square root of both sides:

x²  = 1/4

√(x²)  = √(1/4)

x =  √(1/4)

x = ± 1/2

Answer:

y = -4

Step-by-step explanation:

3y - 2(5y - 7) = -9y + 6 (Given)

3y - 10y + 14 = -9y + 6 (Distribute)

-7y + 14 = -9y + 6 (Add like terms)

2y + 14 = 6 (Add 9y on both sides)

2y = -8 (Subtract 14 on both sides)

y = -4 (Divide 2 on both sides)

You can check by substituting the solution for y:

3(-4) - 2(5(-4) - 7) = -9(-4) + 6

-12 - 2(-20 - 7) = 36 + 6

-12 - 2(-27) = 42

-12 + 54 = 42

42 = 42

Answer: 8mm, to find radius from diameter just split it in half.

Answer:

40%

Step-by-step explanation:

Move the period over twice then place the percentage sign where you moved the period to

Answer:

40%

multiply both numerator and denominator by 100. You do this to find a equivalent fraction having 100 as the denominator. The fraction is 40 over 100, 100 represents the whole thing 40 is the part so it's basically part over whole. 40% is your answer. I'm sorry if my explanation made no sense

Option B is the correct answer

Step-by-step explanation:

By exterior angle theorem:

[tex] m \angle \: 1 + m \angle \: 2 = m \angle \: 4[/tex]

Answer:

8.5 %

Step-by-step explanation:

The formula used her :

\text{Percent error }=\dfrac{|\text{Estimated value-Actual value}|}{\text{Actual value}}\times100Percent error =

Actual value

∣Estimated value-Actual value∣

×100

Given : A hospital bill is estimated to be $480.00 it ends up actually costing the patient $524.50 .

Then, the percent of Error in the bill will be :

\begin{gathered}\text{Percent error }=\dfrac{|480-524.50|}{\text{524.50}}\times100\\\\=\dfrac{|-44.5|}{524.50}\times100\\\\=\dfrac{44.5}{524.50}\times100\\\\=8.48427073403\approx8.5\%\end{gathered}

Percent error =

524.50

∣480−524.50∣

×100

=

524.50

∣−44.5∣

×100

=

524.50

44.5

×100

=8.48427073403≈8.5%

[Rounded to the nearest tenth]

Hence, the percent of Error in the bill = 8.5%

Step-by-step explanation:

absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign. For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5. The absolute value of a number may be thought of as its distance from zero along real number

Answer:

1- solve for x

2- put it in the bottom left square

Answer:

The right answers are: The sphere gets bigger/The diameter doubles/The surface area quadruples.

Step-by-step explanation:

From Geometry, we remember that surface area and volume of the sphere are represented by:

[tex]A_{s} = 4\pi\cdot r^{2}[/tex] (1)

[tex]V = \frac{4\pi}{3}\cdot r^{3}[/tex] (2)

Where [tex]r[/tex] is the radius of the sphere. The diameter is two times the radius of the sphere.

If the radius of the sphere is doubled, then the sphere gets bigger, the diameter is double, the surface area is doubled and the volume is octupled. Therefore, the right answers are: The sphere gets bigger/The diameter doubles/The surface area quadruples.

Answer:

The sphere gets bigger , the diameter doubles,  the surface area quadruples

Answer:

(-2,8)

Step-by-step explanation:

To solve by substitution, first isolate a variable in one of the equations. Then, substitute the value of the variable from that equation into the other equation, giving either the x or y value of the solution. Finally, substitute that answer back into one of the two equations, finding the other missing value.

1) For both of the equations, the variable y has already been solved for. So, we can choose to substitute whatever y equals in one equation for the y in the other equation. Any choice is fine - I chose to substitute -4x for the y in y = 3x + 14.

[tex](-4x) = 3x + 14\\-7x = 14\\x = -2[/tex]

2) Now that x has been solved for, substitute the value for the x in one of the equations. Any choice is fine here, too - I chose to substitute -2 in y = -4x:

[tex]y = -4(-2) \\y = 8[/tex]

3) Both the x and y value of the solution has been solved for. x = -2 and y = 8. Therefore, the solution is (-2,8).
