Answer:

A =78.5 in^2

Step-by-step explanation:

The area of the circle is given by

A = pi r^2

A = pi * r^2

A = 25 pi

Using 3.14 for pi

A = 25 (3.14)

A =78.5 in^2

Shane biked 1 mile than three times the number of miles lissette bike a total of 7 miles. Write an equation to determine how man
bagirrra123 [75]

Answer:

Equation : x + 1 + 3x = 7

Miles Lissette biked : 3/2 miles

Step-by-step explanation:

<em>Step 1: Determine the total number of miles biked.</em>

From my understanding. 7 miles is the total number of miles biked by both.

<em>Step 2: Assume the values</em>

Miles Lissette biked = x

Miles Shane biked = 1 + 3x

<em>Step 3: Add miles biked by Lissette and Shane which will be equal to total miles. </em>

Equation for miles Lissette biked: x + 1 + 3x = 7

4x + 1 = 7

x = 6/4

<em>Step 4: Simplify</em>

x = 6/4

x = 3/2

Therefore, the equation for miles Lissette biked is x + 1 + 3x = 7 and Lissete biked for 3/2 miles.

Vivenne, John and nassim ran for 6th grade class president. Vivenne got four votes for every 3 votes that John got. Nassim got t
liq [111]

Answer:

John received 10% of the overall votes.

Step-by-step explanation:

Let us assume that the number of votes John got  = m

So, the number of votes Vivienne received =   3 times (John's share )

 = 3  times m   =  3 m

Also, The number of Votes Nassim received = 2 times ( Vivienne's share)

2 x (3 m)   = 6 m

Total Votes in the grade 6  

= Votes received by { John + Vivienne + Nassim}

= m + (3 m) + (6 m) = 10 m

Hence, the total number of students who voted in grade 6  = 10 m

\textrm{The percentage of John's Votes }  = \frac{\textrm{Number of votes John received}}{\textrm{Total number of votes }}  \times 100

= \frac{m}{10m}  \times 100 = 10

or, The percentage of John's Votes  = 10%

Hence, John received 10% of the overall votes.
