Answer:
Step-by-step explanation:
Cross multiplication.
Dividing both sides by .
Taking the square root of both sides.
Solution:
Given ratio - 3:5
1 part = 3
2 part = 5
Total no. of parts = 3 + 5 = 8 parts
400 / 8 = 50
3 * 50 = 150
5 * 50 = 250
I think that's it :D
You just add all of it. You can use a calculator.
$19.36 + $21.75 + $32.26 =
$41.11 + $32.26 =
$73.37
The answer is B. $73.37
Answer:
Step-by-step explanation:
we know that
The area of a triangle is equal to
------> equation A
where
b is the base of the triangle
h is the height of the triangle
In this problem the dimensions of the triangle are increased by a scale factor of
so
the new dimensions of the triangle are
The new area of the triangle will be
------> equation B
Substitute equation A in equation B
option B
