Answer:
The answer is 20ft
Step-by-step explanation:
Since they both cast shadows at the same time, the ratios of their height to their respective shadow length will be the same.
Hence; we'll equate both ratios to find the length.
House= 12/9
Flag pole= h/15
Equating both:
12/9 = h/15
h x 9 = 12 x 15
h = 180/9
h = 20ft
Models can be used to describe, extend, and make generalizations about certain mathematical situations.
A (-1,2)
using substitution:
substitute-2x for y in the second function
7x - 8(-2x) = -23
solve for x
7x + 16x = -23
23x = -23
x = -1
plug x = -1 into a function to find y, in this case ill plug it into the first
y = -2(-1)
y = 2
since x = -1 and y = 2
the answer is A (-1,2)
Answer:
Since 1/2 mile is equal to 4/5 mile, so we will solve this using proportions. 1/2 inches : 4/5 mile : ? : 1 mile. So the answer would be 5/8 inch. We cross multiply 1 by 1/2 then divided by 4/5 which gave us 5/8.
Step-by-step explanation:
So B 5/8 PLEASE MARK BRAINIEST.
