Answer:
0.161
Step-by-step explanation:
Answer:
21.25
Step-by-step explanation:
We can use the Pythagorean theorem to solve
We have the two legs and are looking for the hypotenuse
a^2 + b^2 = c^2
17^2 +12.75 ^2 = c^2 where c is the diagonal
289 +162.5625 = c^2
451.5625 = c^2
Take the square root
sqrt(451.5625) = sqrt(c^2)
21.25 =c
Answer:
D) x=16 and x=-16
Step-by-step explanation:
D) x=16 and x=-16
If you replace x with either one of them and then take the absolute value, you would have 8.
Note: Consider 84 instead of 83 because the value of x is a decimal value of 83 which is not possible.
Given:
Compound ratio of 7:5 and 8:x is 84:60.
To find:
The value of x.
Solution:
Compound ratio of 7:5 and 8:x is 84:60.
By cross multiplication, we get
Divide both sides by 1420.
Therefore, the value of x is 8.
