In this question there is a small trick that needs to be understood. Basically the ratio in the question is given as a decimal. It can be expressed as a ratio as well.
Ratio of students that voted for winner to the total number of voters = 95:100
The total number of students that voted = 60
Let us assume the common ratio to be = x
then
100x = 60
x = 60/100
   = 0.6
Then
The number of votes that the winner got = 95 * 0.6
                                                                 = 57
So 57 students voted for the winning candidate.

<u>Corrected Question</u>

Matt makes $80 a month mowing lawns. His friend James also mows lawns, but he makes x dollars less per  month than Matt does. James makes a total of $816 per year. How much less each month does James make than Matt? Solve the linear equation to find the value for x

. Remember that x represents how much less per month James makes than Matt

Equation: 12(80 – x) = 816

Answer:

x=$12

Step-by-step explanation:

To solve the given equation

12(80 – x) = 816

First, we distribute:

960-12x=816

Collect like terms

12x=960-816

12x=144

Divide both sides by 12

x=12

Therefore, James makes $12 less than Matt every Month.

A kite has a perimeter of 70 centimeters. One of the shorter sides measures 16 centimeters. What are the lengths of the other th
Sveta_85 [38]
A kite has 2 short sides and 2 long sides. The 2 short sides are equal. The 2 long sides are also equal. This means that the other short side is 16cm. And the remaining longer sides can be found like this:
let's pretend *y* is the long side
2*y = 70 - 16 - 16. (two of the long sides = 70 - short side - another short side)
so use algebra to find y.
2*y = 38
y = 19 so the long sides are both 19cm each
Your final answer: 16cm, 19cm, 19cm

The horizontal viewing angle is the angle subtended by a straight line from
SSSSS [86.1K]

The measure of the arc is given as π/2. See the explanation below.

<h3>What is an arc?</h3>

An "arc" is a curve that connects two points in mathematics.

It can also be depicted as a section of a circle. It is essentially a portion of a circle's circumference. An arc is a kind of curve.

<h3>What is the calculation for the above solution?</h3>

Note that the viewing angle is 45°.

Thus, the center angle is:
45 X 2 = 90°

Measure of the arc therefore is:
= (π/180°) x 90

= π/2

How many times greater is the value of 3 in 300 than the value of the 3 in 30
Vikki [24]
Well it sounds like you mean smaller, not greater. 3/300 = 1/100 while 3/30 = 1/10. So 3 out of 300 is 10 times SMALLER than 3 out of 30.
