- Im learning about this , so im not really sure
Hmm let's say
c = commercial launches
n = non-commercial launches
we know the total of launches were 53 for that year, so
c + n = 53
we also know that, whatever "c" is, "n" is "<span>was one more than three times" that
so... three times "c", 3 * c or 3c
one more than that?
3c + 1
so.. whatever "c" is, n = 3c + 1
</span>
<span>
solve for "c", to see how many commercial launches were there
what about "n"? well, n = 3c + 1</span>
Answer:
Step-by-step explanation:
The x-intercept of a line exists where y = 0. So first we will set each of those lines = 0:
4x - 18 = 0 and -2x + k = 0. In order for the x-intercepts to be equal, we have to solve each equation for x and then set those expressions equal to each other.
4x = 18 so
x = 9/2.
-2x = -k so
x = k/2. If the x-intercepts are the same value, then
so, obviously,
k = 9

Step-by-step explanation:
The volume of a pyramid or cone is:
V = ⅓ Ah
where A is the area of the base and h is the height.
The pyramid has a square base, so:
A = s²
A = (7 cm)²
A = 49 cm²
The height is 14 cm, so the volume is:
V = ⅓ (49 cm²) (14 cm)
V = 686/3 cm³
V ≈ 228.67 cm³
