Hello!

to find a percent, convert the percent to a decimal by dividing by 100

13.8 / 100 = 0.138

then multiply the divided percent by the number you needed to find the percentage of

$29.90 * 0.138 = $4.1262

since you're using currency, round the the nearest hundredth

your final answer is $4.13

I hope this helps, and have a nice day!

a local school has a gymnasium that is 48ft long, 36ft wide with an 18ft high ceiling. the school maintenance staff is painting

pshichka [43]

Answer:

Step-by-step explanation:

Let's first measure the four walls. We'll have 2 walls 48 ft wide x 18 ft high (the longer walls), then 2 walls 36 ft x 18 ft high.

These are rectangles we can easily calculate the area:

longer walls: 2 (48 * 18) = 2 * 864 = 1,728 sq ft

shorter walls: 2 (36 x 18) = 2 * 648 = 1,296 sq ft

Total of the walls: 1,728 + 1,296 = 3,024 sq ft.

Now, we assume they'll paint everything and that there are no windows.

Each can covers 400 sq ft.

If we divide 3,024 by 400 we get 7.56

So, they'll need to buy 8 cans of paint to do the job. In such problems, we always round up, otherwise they wouldn't have enough paint.

List the components in the proportion relationship used to find missing value in scale drawing?

Phoenix [80]

<h2>Explanation:</h2><h2></h2>

When we have relationships between two variables and their ratios are equivalent, we call this as proportional relationship. A scale drawing is a model that has been reduced or enlarged from its original size. Suppose you have a horse that measures 1,5m high by 2m long and want to draw a reduced model by a scale factor of 1:10, then your drawing will measure:

$Height=1.5(1/10)=0.15m \\ \\ Length=2(1/10)=0.2m$

So the components are:

Measurements of the original object
Measurements of the drawing
Scale factor

I need help finding the missing angles, please show work

Leno4ka [110]

It's an isosceles triangle, which means base angles are equal.

48 = 6x

48/6 = x

8 = x

48 = 48

Angle y = 180° - (48° + 48°)

Angle y = 180° - 96°

Angle y = 84°

The two missing angles are 48° and 84°.

Answer:

A = 2000(1 +1)^(t/9)

$64,000

Step-by-step explanation:

The growth rate is 100% in 9 years, so the equation can be written ...

A = 2000(1 +1.00)^(t/9)

The amount in 45 years is ...

A = 2000(2^5) = 2000×32 = 64,000 . . . dollars
