There are 4 walls.  Each wall has the area of length (13.5) x width (7.55).

SA = 4 ( 13.5) (7.55)

     = 407.7 ft²

Next, convert ft² to meters² (1 ft = 0.3048 meters)

407.7 ft² x (\frac{0.3048 meters}{1 ft})² = 37.9 meters²

Answer:

not a right triangle

Step-by-step explanation:

We can use the Pythagorean theorem to see if it is a right triangle

a^2 + b^2 = c^2

15^2 + 12^2 = 21^2

225 + 144 = 441

369 = 441

This is not true so it is not a right triangle

In two hours Holden completed 3/4 of his race how long will it take Holden to complete the entire race?
vivado [14]

Answer:

\frac{1}{4} = 50 Minutes

Whole Race Time : 2 Hour and 50 Minutes

Step-by-step explanation:

so 2 Hour = \frac{3}{4} Race completed

we need to find what 1/4 Race = x Hours

so 200 divided by 4 because \frac{3}{4} Race is done.

we need to find how long to finish the whole race also known as \frac{4}{4}.

200 divided by 4 = 50

so Holden still need 50 Minutes to finish the race.

Value of m varies directly as value of n and n=5 when m=12. What is n when m=18?
ohaa [14]
Simplify the problem down, so:

m = 12 & n = 5
m = 6 & n = 2.5 <span>(divided each number by 20)
</span>
Now m is a factor of 18. Multiply each number by 3.
Answer: m = 18 & <span>n = 7.5</span>

Determine how much money you will have after 8 years if you invest 4,000$ at 7% compounded monthly
Solnce55 [7]
You would get $26,880.
0.07*4000= 280; so $280 are added every month
There are 96 months in 8 years, so multiply 280*96 which =26,880
