A rectangular one-story building covers an area of 4,700 square feet. The ceilings are 7 feet high. What is the volume of the in

kvv77 [185]

Area (4700) = length*width
Volume= length*width*height
Volume= 4700*7
Volume= 32900 square feet

I'm almost 100% sure this is correct, maybe just double check to see if it makes sense based on what you're learning. Hope this helps, and good luck!

I'll just help quickly with a couple of expressions that are equivalent.
3(m+5+9m)
If you solve it out, you get 3m+15+27m.
Simply the expression to get 30m+15.
You can regroup to make another expression 5(6m+3) which is also equal.

the length of the highway is 600 miles is 2 in represent 75 miles what is the length of the highway on the map

Wittaler [7]

75miles = 2in
600miles= x in
cross multiply
600× 2 = 75 × x
divide both sides by 75
x = 16 in
therefore the length of the highway on the map is 16 in

Here is a riddle:

lilavasa [31]

Answer:

The system of inequalities that represents this situation will be:

$f + s < 10$

$f - s > 3$

Step-by-step explanation:

Let 'f' represent the first number

Let 's' represent the second number.

Given that the sum of the two numbers is less than 10. As 'less than' can be represented by '<'.

so the inequality would be: f + s < 10

Given that If we subtract the second number from the first, the difference is greater than 3. As 'greater than' can be represented by '>'.

so the inequality would be: f-s > 3

Thus, the system of inequalities that represents this situation will be:

$f + s < 10$

$f - s > 3$
