The amount left in the fund decreases by $110 for each desk purchased.
We suspect that each new desk probably costs $110.

Answer:

$110 is the decrease in the school desk's fund for each new desk is purchased.

Step-by-step explanation:

We have to calculate the amount of money left in the school's desk fund when a new desk is purchased.

From the given link we find two points (2, 480) and (5, 150), and the decrease in fund when a desk is purchased will be denoted as

Decrease in school's desk fund after a new purchase = Change in y coordinates of the points / difference in x-coordinates

= (480-150)/(5-2) = 330/3 = $110

Answer is $110.

What is 9 divided by 765 <br><br> please show the work i really need help
BartSMP [9]
765 / 9 = 85
9*100 = 900 but this is too much
900 - 765 = 135
9 goes into 135 15 times (9*10=90 which leaves 45 which is 9*5 so 5+10) so you minus 15 from the 100 that made 900
so 100 - 15 = 85

the surface area of a sphere is 1,017.36 square inches.what is the volume of the sphere? use 3.14 for pi
emmasim [6.3K]

Answer:

<em>Area = 254.34 inches ³</em>

Step-by-step explanation:

The formula to find the surface area of a sphere is:

SA = 4\pi r^{2}

To find the volume of the sphere, we first need to figure out the radius (r) of the sphere. We can accomplish this by reversing the formula that was used to find the surface area. (1017.36 in^{2})

SA = 4\pi r^{2}

1017.36 = 4\pi r^{2}

Divide both sides by pi (3.14).

1017.36 = 4\pi r^{2}

324 = 4 r^{2}

Divide both sides by 4.

324 = 4 r^{2}

81 = r^{2}\\

Find the square root of both sides.

81 = r^{2}\\

\sqrt{81} = r

<em>radius = 9</em>

<em />

Insert the value of the radius into the formula for finding the volume of a sphere. (A=\pi r^{2})

(A=\pi r^{2})

A=\pi (9)^{2}

A=\pi (81)

A = 254.34

<em>Area = 254.34 inches ³</em>

<em />

Please help I don’t understand
KIM [24]

Answer:

The equivalent ratios are:

16:10

8:5

48:30

Step-by-step explanation:

It is given that the ratios are equivalent ratios. So all the ratios will simplify to the same ratio. We can use this to find the ratios.

given ratio is:

16:10

which simplifies to

8:5

We can observe that the second ratio will be same 8:5

Now,

\frac{8}{5} = \frac{x}{30}\\x = \frac{8}{5} * 30\\x = 48

Hence,

The equivalent ratios are:

16:10

8:5

48:30
