Answer:
28ft^2
Step-by-step explanation:
you only need 2 things to find the area of the triangle, base and height. The formula for finding the area is 1/2(base x height)
if we plug the numbers we are given into the formula we find
1/2(7x8)
1/2(56)
28
we find that the area of this triangle is 28ft^2
Answer:
Quarters = 20
Dimes = 14
Step-by-step explanation:
Dime = x = 10 cent = $0.1
Quarter = y = 25 cent = $0.25
x + y = 34 - - - (1)
0.1x + 0.25y = 6.40 - - - - (2)
From (1)
x = 34 - y
0.1(34 - y) + 0.25y = 6.40
3.4 - 0.1y + 0.25y = 6.40
3.4 + 0.15y = 6.40
0.15y = 6.40 - 3.40
0.15y = 3
y = 3 / 0.15
y = 20
x = 34 - y
x = 34 - 20
x = 14
Quarters = 20
Dimes = 14
