Answer:
280 degrees
Step-by-step explanation:
To change radians to degrees, we can use the conversion factor
180/pi
14 pi/9 * 180/pi
Canceling like terms
14/9 * 180
280 degrees
Answer:
-63+14x
Step-by-step explanation:
7(-9+2x)=7(-9)+7(2x)=-63+14x
The area for a trapezoid is A=1/2(b*1+b*2)h
Your base is your two parallel sides, and your parallel sides in this case is 5cm and 11cm, so that means your bases are 5&11. Your height is 4.
A=1/2(5+11)4
In order to do this you need to do the distributive property first.
1/2 x 5 = 2 1/2
1/2 x 11 = 5 1/2
Then next you need to do:
2 1/2 + 5 1/2 = 8
The last step is to do:
8 x 4 = 32
SO THE ANSWER IS 32.
Answer:
50 and 60 mph respectively
Step-by-step explanation:
Step one:
given data
total distance= 450 miles
time take= 9 hours
Required
Tom and Tammy's average speed
Step two:
Tom's average speed= 450/9
= 50 miles per hours
Tammy's average speed= 450/7.5
= 60 miles per hours
The answer is 3/10 since percentages are out of 100
