Answer:
h = 9 cm
Step-by-step explanation:
A rectangular pyramid has a volume of 315 cm^3.
The base has a width of 15 cm and a length 7 cm.
Find the height h of the pyramid .
<u>Vol = 1/3 (base area) h</u>
where base area = 7 x 15 = 105 cm²
vol = 315 cm³
plugin values into the formula
315 = 1/3 (105) h
h = <u> 315 </u>
(1/3 * 105)
h = 9 cm
Remark
Anything to the 0 is one. 15^0 = 1 It's an odd looking fact but it is true.
8^3 means 8*8*8
8 * 8 = 64
64 * 8 = 512
Answer: 512 + 1 = 513
Answer:
6
Step-by-step explanation:
First, we'll need to remove the parentheses: 3 - 5h = -18h + 81.
Then, we will move the variable to the left-hand side and change its sign, giving us 3 - 5h + 18h = 81
Then we must collect like terms, giving us 13h = 81 - 3
Finally, to get our answer, we must divide both sides of the equation by 13, giving us the answer of 6.
Consider
2x – y = 7
y = 2x + 3
Subst. 2x+3 for y in the first equation: 2x - (2x + 3) = 7
This boils down to 0 + 3 = 7, which simply is not true and can never be true.
Thus, this system of equations has no solution.
