after a school election,Jamie had 3/8 of the votes Richard the only other candidate had 75 votes how many people voted for jaime
dalvyx [7]
Jamie and Richard are the only contestants of the election.

Jamie got 3/8 of the total votes.

Richard got = 1 - 3/8 = (8-3)/8 = 5/8 of total votes

Number of votes Richard got = 75

So 5/8 of total votes = 75

Total votes = 75 ÷ 5/8 = 75 × 8/5 = 120

Jamie got = 120 - 75 = 45 Votes

The side links of a triangle are 3 m, 4 m common 5 m. Suppose the side links are multiplied by four. Describe the change in peri
andrew-mc [135]

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Side links are : 3m, 4m, 5m

The perimeter of a triangle = (a + b + c)

Perimeter 1= (3 + 4 + 5) = 12m

If the side links are multiplied by 4 :

3*4 = 12 m

4*4 = 16m

5*4 = 20m

Perimeter2 = (12 + 16 + 20) = 48 m

Comparing the perimeters:

Perimeter 1 = perimeter 2

12 = 48

Hence, perimeter also increases by 4 folds
