Answer:
C
Step-by-step explanation:
Two pyramids are similar. It means that their side lengths are proportional.
So, let's see the proportionality constant from SMALL PYRAMID to LARGE PYRAMID.
The corresponding length of 8 in small pyramid is 24 in large pyramid. We ask ourself: "8 times WHAT gives us 24?"
This is the proportionality constant (aka "k").
So, 8 times "3" is 24. So the proportionality constant is "3".
k = 3
Now, the height of small pyramid is 6 and height of large pyramid is "x". These sides will be same way proportional. So, we can say:
6 times the proportionality constant (3) would give us x
So,
6 * 3 = x
x = 18
Correct answer is C
Answer:
D. 1-2i is your answer.
Step-by-step explanation:
What you're doing is adding them together.
<em>4 + -3 + -7i + 5i = 1-2i</em>
D. 1-2i is your answer.
Answer:
the answer is D, acute angles
Step-by-step explanation:
all of the angles in the triangle are less than 90°
Answer:
2k + 4 > k + 11
Step-by-step explanation:
Keywords:
more - addition
twice - multiplication
greater than - >
sum - addition
4 more than twice the number k
2k + 4
Greater than
>
Sum of k and 11
k + 11
2k + 4 > k + 11
Solve for k if needed.
2k + 4 > k + 11
2k > k + 7
k > 7
Best of Luck!
