Answer:
The answer is 3.53
Step-by-step explanation:
The formula for a semicircle is pi x r2 divided by 2, so divide the diameter by 2, then plug that in as the radius into the formula.
Assuming that the base is 5 cm and the height is 12 cm, so
by dilating the legs by a scale factor of 2/3, the new dimensions are:
base = 5 cm * (2 / 3) = 10/3 cm
height = 12 cm * (2 / 3) = 8 cm
So the area of a right triangle is calculated using the
formula:
A = b h / 2
A = (10/3) * 8 / 2
<span>A = 13.33 cm^2</span>
Answer: Rational
Step-by-step explanation: To determine whether -3/4 is rational or irrational, remember that all fractions positive or negative are rational numbers.

Answer:
15:12:3= 15 boys 12 girls and 3 teachers
Step-by-step explanation:
There are 5 boys in the School and 4 girls in the School and 1 teachers in the School
Because you got to try to look for a number that you can divide by all three numbers. And that number is 3. Because if you do 15 ÷ 3 =5, 12÷3=4, 3÷3=1
