Step-by-step explanation:
By using formula of h^2=p^2+b^2
h=20
p=x
b=10
Now,
p=root h^2-b^2
x=root 20^2-10^2
x=root 400-100
x=root 300
x= 10root3
Answer:
Step-by-step explanation:
If all were dimes, you'd have $3.00. You have $0.40 less. Each dime that is replaced by a nickel subtracts $0.05, so there are $0.40/$0.05 = 8 nickels. That leaves 30-8 = 22 dimes.
You have 22 dimes and 8 nickels in your wallet.
Hi I don't know has to do this
Answer:
The angle = 144 degrees.
Step-by-step explanation:
Look at it this way (it is a proportion question)
30 people would require a pie chart made of a full circle (360 degrees)
12 people would require x part of the pie chart.
30/360 = 12 / x Cross multiply
30x = 360 * 12 Simplify the right
30x = 4320 Divide by 30
30x/30 = 4320/20
x = 144 Answer
Answer:
4 if no tax is included because 4 times 12 equals 48
