Answer:

34

Step-by-step explanation:

\frac{2}{5}*85

Long way

  1. multiply the two numerators
  2. multiply the two denominators
  3. simplify the new fractions

\frac{85}{1}*\frac{2}{5}  \\ \\ \frac{170}{5} \\ \\ =34

short way

-can be simplified before mulitplying

  1. factor out common factors in the numerator and denominator

\frac{85}{1} *\frac{2}{5} \\ \\ \frac{17}{1}*\frac{2}{1} =34

Think 85 and 5 as nickels. You need 20 nickels to make 100. Subtract 100 by 85 to get 15. You get 3 nickels and 17 nickels. 17 is the common factor. Multiply 17 by 2 to get your answer.

In the last election, candidate b received twice as many votes as candidate
Andrej [43]
A + b + c = 109,000
b = 2a
c = a - 15,000

a + (2a) + (a - 15,000) = 109,000
4a - 15,000 = 109,000
4a = 109,000 + 15,000
4a = 124,000
a = 124,000/4
a = 31,000

b = 2a
b = 2(31,000)
b = 62,000 <==== candidate b received 62,000 votes

c = a - 15,000
c = 31,000 - 15,000
c = 16,000

The diameter of a circle is 8 cm. Find its area in terms of π.
Verizon [17]

Answer:

16\pi cm^2

Step-by-step explanation:

Area of a circle is equal to \pi r^2, where r is the radius

A=\pi r^2

A diameter is twice the length of the radius. (8/2)

So the radius is 4 cm.

r^2=4^2=16

so the Area is 16\pi
