Answer:
Step-by-step explanation:
First convert km to meters
143000 km = 143,000,000m = 1.43*10^8 m
Now convert 10 billion to scientific notation1 00
10 billion = 1 * 10^10
What this means is that 1 * 10^10 meters in outer space = 1 meter for the scale model.
Now show what the ratio is for
1.43*10^8
======== Divide by the denominator
1 * 10^10
1.43 * 10^(8 - 10)
1.43 * 10 ^ - 2 meters
Answer: 0.0143m or B
Answer:
46%
Step-by-step explanation:
Answer:
x = 8.5
L = 17
W = 6.5
Step-by-step explanation:
P = 2*(L + W)
W = x - 2
L = 2x
P = 47
47 = 2 * (2x + x - 2)
47 = 2 * (3x - 2) Remove the brackets.
47 = 6x - 4 Add 4 to both sides.
47 + 4 = 6x - 4+4 Combine
51 = 6x Divide by 6
6x/6=51/6 Combine
x = 8 3/6 or 8.5
x = 8.5
========
L = 2*x
L = 2*8.5
L = 17
=====
W = x - 2
W = 8.5 - 2
W = 6.5
Answer:
y = -⅛(x - 3)² + 3
Step-by-step explanation:
(x - h)² = 4p(y - k)
h = 3
k + p = 1
k - p = 5
2k = 6
k = 3
p = -2
(x - 3)² = 4(-2)(y - 3)
(x - 3)² = -8(y - 3)
y = -⅛(x - 3)² + 3
The answer is x equals -3 and y equals 0
