Answer:
x = 5
y = 40°
Step-by-step explanation:
the median and the base of the large triangle are parallel so angle y has the same measure as the one labeled as 40°
the median is half the base of the large triangle, so 5x = 8x + 10/2
cross-multiply: 10x = 8x + 10
2x = 10
x = 5
Answer:
8
Step-by-step explanation:
The constant of proportionality bus the amount earned by Ronnie, E, all over the corresponding hours he used in working, h.
Constant of proportionality = 
From the graph given, when h = 5, E = 40.
Therefore:
Constant of proportionality = 
Answer:
Growth.
Step-by-step explanation:
The growth factor is 1.18 ( > 1) and the exponent is > 0.
1. The formula for the area of a rectangle is:
A=LxW
L: The lenght of the rectangle (L=2W).
W: The width of the rectangle.
2. Let's substitute L=2W into the formula A=LxW:
A=LxW
A=2WxW
A=2W²
3. When we clear "W", we obtain:
W²=A/2
W=√(A/2)
4. We already know the value of "A", so:
W=√(50 ft²/2)
W=√(25 ft²)
W=5 ft
5. Now, we must substitute the value of "W", into L=2W:
L=2W
L=2(5 ft)
L=10 ft
6. The perimeter of a rectangle is:
P=2L+2W
7. We know the value of "L" and "W", therefore:
P=(2x10 ft)+(2x5 ft)
P=20 ft+10 ft
P=30 ft
