Jayden received a $600 signing bonus when he accepted a job as an executive assistant. If he makes $26 an hour, which equation m

IrinaVladis [17]

Given, the signing bonus of Jayden = $600.

Jayden makes $26 in an hour.

Jayden works for x hours.

For 1 hour he makes = $26

So for x hours he will make = $ $(26)(x)$ = $ $(26x)$

So the total pay of Jayden = The sum of the signing bonus and the total pay for x hours.

The total pay of Jayden = $( $600+(26x)$ )

Given, jayden's total pay = y dollars.

So we can write the equation as $y=600+26x$

we have got the required equation $y= 26x +600$

The volume of a sphere is 256/3π cm3.

slava [35]

the surface area of the sphere is π/4 cm^3

<h3>How to determine the surface area</h3>

It is important to know the formula for surface area and volume of a sphere

Surface area = $\frac{4\pi }{r^2}$

Volume = $\frac{4}{3} \pi r^3$

First, let's determine the value of radius, r

The value for volume was given as 256/3π cm3.

$\frac{256}{3} \pi = \frac{4}{3} \pi r^3$

Pi cancels out and we have cross multiply to get the radius

$256 * 3 = 4 * 3 r^3$

$12r^3 = 768$

Make r the subject of the formula

$r = \sqrt[3]{\frac{768}{12} }$

$r = \sqrt[3]{64}$

r = 4

Let's substitute to find the surface area

Surface area = $\frac{4\pi }{4^2}$

Surface area = π/4

Surface area = π/4 cm^3

Thus, the surface area of the sphere is π/4 cm^3

A rectangle of length 10 units and width 5 units is shown. Inside this rectangle is another rectangle of length 9 units and widt

beks73 [17]

Hi there!

First, we need to find the area of the rectangles.

10 × 5 = 50
9 × 3 = 27

Now, we find the percent of increase.

27 ÷ 50 = 0.54

Convert into a percentage:

0.54 = 54%

And subtract from 100%.

100% - 54% = 46%

The answer is 46%.

Hope this helps!
