One hour and thirty minutes
Answer:
a. p = 6
b. q = 4
c. r = 8
d. s = 10; t = 8.3
Step-by-step explanation:
1. a. The side length of two similar triangles are proportional, therefore:
Cross multiply
Divide both sides by 15
p = 6
b. Based on the midsegment theorem,
c. The side length of two similar triangles are proportional, therefore:
Multiply both sides by 20
r = 8
d. The side length of two similar triangles are proportional, therefore:
Multiply both sides by 6
s = 10
Multiply both sides by 5
t = 8.3 (nearest tenth)
Area = (bh)/2
b = 19, h = 11
Plug in the value
Area = (19 * 11)/2
Area = 209/2 = 104.5
Solution: 104.5 square inches
Explanation:
The formula isnt correctly written, it should state:
You have to start from and end in a³+b³. On your first step, you need to use the distributive property.
This is equal to
Note that the second term, -a²b, is cancelled by the fourth term, ba², and the third term, ab², is cancelled by the fifht term, -b²a. Therefore, the final result is a³+b³, as we wanted to.
Answer: 153.86cm
Step-by-step explanation:
A bowl represents a circle
Area of a circle is pir2
But here we are given the diameter as 14
Diameter = 2radii
14=2r
R=14/2
R=7
So radius of the bowl is 7cm
Back to the formula
Area of a circle is pir2
Pi=3.14
Substitute for each value
Area= 3.14×7^2
Area= 3.14×49
Area= 153.86cm
Area= ~154cm
