Answer:
1. 62.5
2. 66.25
Step-by-step explanation:
25% of 50 is 12.5 add that to 50 is 62.5
6% of 62.5 is 3.75 so 3.75+62.5 is 66.25
Answer:
D. They have the same slope ( rate of change) and the same y-intercept.
Step-by-step explanation:
I y = 1.2x + 0.4.
II The slope is (10-4)/(8-3) = 6/5= 1.2.
Its equation is
y - 4 = (1.2)(x - 3)
y = 1.2x - 3.6 + 4
y = 1.2x + 0.4.
Answer:
8x-8
Step-by-step explanation:
10x-2x=8x
-3-5=-8
Answer:
60
Step-by-step explanation:
40% = 0.4
150(0.4) = 60
Answer:
x = 75 m
Step-by-step explanation:
This is a problem of similar triangles solved using proportions.
In similar triangles, corresponding side lengths are proportional.
Here the small and large triangles are similar because the have all three angles congruent.
By proportions, identifying corresponding sides,
x/45 = 50/30
solve for x
x = 45*(50/30) = 75 m
