13/20,3/5,29/50,14/25,53/100
Answer:
x = 30
y = 2
Step-by-step explanation:
Please note: the value for x is correct only if this triangle is a right triangle.
This can be solved because 2(5y) = 20 and because if a triangle has all congruent angles then its side lengths are also congruent.
Answer:
$12.75
Step-by-step explanation:
Skubic Family-
22.75 = 5.25 + 7x
17.5 = 7x
2.5 = x
Therefore the cost for each person is equal to $2.5
Shaw Family-
2.5(3) + 5.25
7.5 + 5.25 = $12.75
Answer:
The volume of the ball is 256 cm³
Step-by-step explanation:
we know that
The density is equal to the ratio of the mass by the volume
D=m/V
Solve for V
The volume is equal to the ratio of the mass by the density
V=m/D
In this problem we have
m=128 g
D=0.5 g/cm³
substitute
V=128/0.5=256 cm³
