Answer:
Area of shape = 187 cm²
Step-by-step explanation:
Given:
Length of rectangle = 15 cm
Width of rectangle = 9 cm
Height of triangle = (22-9) cm = 13 cm
Base of triangle = (15-7) cm = 8 cm
Find:
Area of shape
Computation:
Area of shape = Area of rectangle + Area of triangle
Area of shape = (l)(b) + (1/2)(b)(h)
Area of shape = (15)(9) + (1/2)(8)(13)
Area of shape = 135 + 52
Area of shape = 187 cm²
Answer:
complementary
b = 45 deg
Step-by-step explanation:
Angles b and 45-deg are complementary since their measures ad to 90 deg.
45 + b = 90
b = 45
Answer:
y=¾(4x-20)
y=3x-15
Final answer= y - 3(x+12)
=y - 3x-36
=3x-15-3x-36
= -51
1) Unit Rate = 26:1
We already know that for every 3 gallons, you can travel 78 miles. Divide 78 by 3 to get 26. The 26 stands for how many miles you can travel on one gallon.
2) Unit Rate = $7.50:1
Since we already know that for every 7 hours, you earn $52.50, divide 52.50 by 7 to get 7.50. The 7.50 represents how much money you earn in 1 hour.
3) Unit Rate = 52:1
Since you can travel 416 miles in 8 hours, divide 416 by 8 to get 52. The 52 represents how many mile you can travel in 1 hour alone.
Here's a little hint too: (If I remember correctly) For unit rates, it's always going to be *any number* to 1. So even if it's a decimal or a negative, the other side of the rate always has to be 1 :)
