In a fund-raising committee of 45 people, the ratio of men to women is 7 : 2. Find the number of women required to join the exis

bagirrra123 [75]

Answer:

18 women

Step-by-step explanation:

Sum the parts of the ratio, 7 + 2 = 9 parts

Divide 45 by 9 to find the value of one part of the ratio.

45 ÷ 9 = 5 ← value of 1 part, thus

7 parts = 7 × 5 = 35 ← number of men

2 parts = 2 × 5 = 10 ← number of women

We require to change the ratio to 5 : 4

The 5 part of the ratio represents the number of men, thus

35 ÷ 5 = 7 ← value of 1 part of the ratio, thus

4 × 7 = 28 ← number of women

Number of women required to join existing committee = 28 - 10 = 18

Use an algebraic equation to find the measure of each angle that is represented in terms of X

professor190 [17]

Answer:

16, 74

Step-by-step explanation:

3x +10 + 12x +50 = 90

15x + 60 = 90

15x = 90 -60

15x = 30

x = 30/15

x = 2

3x + 10 = 3*2 +10 = 6 +10 = 16

12x + 50 = 12*2 +50 = 24 + 50 = 74

Asap help with this PLEASE

12345 [234]

Answer:

124.5°

Step-by-step explanation:

Let the smallest angle be x. Then, the sum of the angles is an arithmetic sequence with first term x, common difference 7, and 8 terms.

Using the sum of an arithmetic series formula,

$\frac{8}{2}(2x+(8-1)(7))=1080 \\ \\ 4(2x+49)=1080 \\ \\ 2x+49=270 \\ \\ 2x=221 \\ \\ x=110.5$

So, the third angle is 110.5+14=124.5
