Answer:
1 : 10.5
Step-by-step explanation:
4 : 42
1 : n
Cross multiply the ratios.
42 × 1 = 4 × n
42 = 4n
42/4 = n
n = 10.5
Answer:
F=7xy²
Step-by-step explanation:
Rewrite the question
4xy * F = 28x^2y^3 Divide by 4xy

Divide the 4 into the 28.
Divide the x into the x^2
Divide the y into the y^3



F = 7xy²
We know that DO and OX have equal side lengths. Since DX's length is 13, we divide 13 by 2 to get 6.5 as our answer for length OX. We also know that DO's length is also 6.5 because when we add 6.5 by 6.5, we get 13 as our total length of DX.
6.5 rounded to is 7.
So, length OX is 7 when rounded and that would be your answer.
It is 101,269 that is the answer for your quistion
