Answer:
12.6 square feet
Step-by-step explanation:
So first we set it up:
18ft is 100% of the original
and the area of the copies are 70%
Copies: x
x/70 = 18/100
70(18) = 1260
1260/100 = 12.6
x = 12.6
Answer:
104 units
Step-by-step explanation:
Given
Shape: Rhombus


Required
Determine the perimeter
The given parameter are the diagonals of the rhombus.
The perimeter (from diagonals) is calculated as thus:

Substitute values for JL and KM





<em>Hence, the perimeter is 104 units</em>
Easy
first term is n=1
so 10th term is n=10
5(10)+100=50+100=150
150 is 10th term
The second one I believe because it’s basiclalu going up one half everytime to get to one
