25% is equal to 1/4, so if 300 is 1/4 and we need to find the total, then we should divide 300 by 4.
300 • 4 = 1200, thus 25% of 1200 is 300!
Hope this helps.
Answer:
2) 360 square inches
Step-by-step explanation:
First of all we have to verify that the base triangle is a right triangle
For this we use Pythagoras
h² = l1² + l2²
13² = 12² + 5²
169 = 144 + 25
169 = 169
Equality is fulfilled by what is a right triangle
Now we need to calculate the area of the triangle
a = (12 in * 5 in) / 2
a = 60in² / 2
a = 30in²
Now we have to calculate the 3 areas of the rectangles
a1 = 10in * 13 in
a1 = 130in²
a2 = 10 in * 12 in
a2 = 120in²
a3 = 10 in * 5 in
a3 = 50in²
Now we must add all the calculated areas and the triangle 2 times
a1 + a2 + a3 + 2a =
130in² + 120in² + 50in² + 2 * 30in²
360in²
The surface area of the prism is 360in²
The range is all possible y values. In this function, range is from -3 < y
* the
To find the perimeter you would add up all of the sides, so:
5x - 2 + 3x + 4 + x - 10
Now you combine the like terms
5x + 3x + x = 9x
-2 + 4 - 10 = -8
So your final answer is C) 9x - 8. I hope this helps!
