The formula for finding surface area is as follows:
SA=2(w*l + l*h + h*w)
First, lets start by plugging in the values
SA = 2 (24*27 + 27*38 + 38*24)
Now, because of the order of operations, we start inside the parentheses and multiply the values
In the end, our result is this:
SA = 2 (648 + 1026 + 912)
Now, we can add everything in the parentheses.
SA = 2 (2586)
Finally, distribute the 2 by multiplying the number in the parentheses by 2
SA = 5172

Therefore, the surface area is 5172 inches^2, or 5172 in^2

In a triangle, measure of one angle is 60º. The measure of one of the remaining two angles is twice the other. Find the measure
inna [77]
As the angle sum of triangle is 180
with one angle is 60 the sum of the remains two angles is 120

let the smallest angle be x
as the larger angle is twice of the smaller angle, it will be 2x
therefore, x+2x = 120, x= 40

so the smallest angel of the triangle is 40 degree

Starting at home, Luis traveled uphill to the gift store for 50 minutes at just 6 mph. He then traveled back home along the same
Georgia [21]

Answer:

Therefore his average speed for the entire trip is 8 mph.

Step-by-step explanation:

Given, In 50 minutes Luis traveled uphill to gift store at 6 mph.

6 mph  means in 1 h= 60 minutes Luis can covered 6 mile.

In 1 minutes Luis can covered \frac{6}{60} mile.

In 50 minutes Luis can covered \frac{6\times 50}{60}  mile

                                                  = 5 mile

Again when he come back at home, the speed was 12 mph.

12 mph  means in 1 h= 60 minutes Luis can covered 12 mile.

Therefore he traveled 12 mile in 60 minutes

He traveled 1 mile in \frac{60}{12}  minutes.

He traveled 5 mile in \frac{60\times 5}{12} minutes

                                   = 25 minutes.

Total distance for the entire trip is =(5+5) mile=10 mile

Total time for the entire trip is = (50+25) minutes = 75 minutes

\textrm{Average speed}=\frac{\textrm{Total distance}}{\Textrm {total time}}

                       =\frac{10}{75} m/min

                      =\frac{10\times 60}{75} mph

                      = 8 mph

Therefore his average speed for the entire trip is 8 mph.

Solve for x. 2 1/2x−3/4(2x+5)=3/8
RUDIKE [14]
2 \frac{1}{2}x- \frac{3}{4}(2x+5)= \frac{3}{8}
2 \frac{1}{2}x- \frac{6}{4}x- \frac{15}{4}= \frac{3}{8}
( 2\frac{1}{2}- \frac{6}{4})x= \frac{3}{8}+ \frac{15}{4}
( \frac{5}{2}- \frac{6}{4})x= \frac{3}{8}+ \frac{15}{4}
( \frac{10}{4}- \frac{6}{4})x= \frac{3}{8}+ \frac{30}{8}
\frac{4}{4}x= \frac{33}{8}
x= \frac{33}{8}=4 \frac{1}{8}
