Answer:
800%
Step-by-step explanation:
<u>Volume of a square based pyramid</u>

where:
- a = base side length
- h = height
<u>Given values</u> for Pyramid A:
- a = 14 inches
- h = 6 inches
Substitute the given values into the formula to find the volume of <u>Pyramid A</u>:

Given:
- Volume of Pyramid B = 3136 in³
To find how many times bigger Pyramid B is than Pyramid A, divide the <u>volume of Pyramid B</u> by the <u>volume of Pyramid A</u>:

Therefore, the volume of Pyramid B is 8 times bigger than the volume of Pyramid A.
8 as a percentage is 800%, since 800/100 = 8.
Therefore, the volume of Pyramid B is 800% the volume of Pyramid A.
To verify this, find 800% of the volume of Pyramid A:
⇒ 800% of 392
= 800/100 × 392
= 8 × 392
= 3136
Answer:
7. x = -2 +/-
8. x = 2 or x = 6
9. x = -2 +/- 
10. t = -3 +/- 
Step-by-step explanation:
7. Subtract 320 from both sides: 4(x + 2)^2 = -320
Divide by 4: (x + 2)^2 = -80
Square root both sides: x + 2 = +/-
. We need to add the imaginary i to this: +/-
= +/-
= +/- 
Subtract 2 from both sides: x = -2 +/- 
8. Add 18 to both sides: 7(x - 4)^2 = 28
Divide by 7: (x - 4)^2 = 4
Square root both sides: x - 4 = +/- 2
Add 4 to both sides: x = 4 +/- 2 ⇒ x = 2 or x = 6
9. Add 5 to both sides: -2(x + 2)^2 = 13
Divide by -2: (x + 2)^2 = -13/2
Square root both sides: x + 2 = +/-
. We again need i: +/-
= +/-
+/- 
Subtract 2 from both sides: x = -2 +/- 
10. Multiply by 5 on both sides: (t + 3)^2 = 35
Square root both sides: t + 3 = +/- 
Subtract 3: t = -3 +/-

Answer:
9
Step-by-step explanation:
Mathematically, OPPOSITES are the same distance away from zero, but on opposite sides of zero on the number line. Use the drawing tools to plot a point at the opposite of each colored point. <u>The absolute value of 0 is 0. Two numbers are opposites if they have the same absolute value but different signs. Opposites are the same distance from 0 on a number line, and they are on opposite sides of 0. The opposite of 0 is 0.</u>
