podryga [215]

The fraction of the girls signed up to play outfield is \frac{2}{15}

<em><u>Solution:</u></em>

Given that Two fifths of the girls in school signed up to play softball

An equal number of girls signed up to play pitcher, infield and outfield

So there are 3 equal groups formed from two fifth

This means that we could divide the 2/5 initial group into 3 equal smaller groups for each play pitcher, infield and outfield

Therefore, fraction of the girls signed up to play outfield is found by dividing \frac{2}{5} by 3

\text{ Fraction of girls play outfield } = \frac{\frac{2}{5}}{3}\\\\\text{ Fraction of girls play outfield } = \frac{2}{5} \times \frac{1}{3}\\\\\text{ Fraction of girls play outfield } = \frac{2}{15}

Thus fraction of the girls signed up to play outfield is \frac{2}{15}

I need help please thanks

Answer:

Vertical angles = 81 degrees

Angle (4y-1) = 99 degrees

Linear pair = 81 + 99 = 180 degrees

Step-by-step explanation:

2x + 5 = 3x - 33 (vertical angles)

33+5 = 3x - 2x

38 = x

3(38) - 33 = 81 degrees

4y - 1 + 81 = 180 (linear pair angles)

4y = 180 - 80

y = 100/4

y = 25

4(25) -1 = 99 degrees
