2/9 of the members are boys in a community service club. if there are 95 more girls than boys, how many girls are there in club?

KengaRu [80]

Answer:

133 girls

Step-by-step explanation:

Total members = x

Number of boys = $\frac{2}{9}x$

Number of girls = $\frac{2}{9}x +95$

Number of boys + Number of girls = total members

$\frac{2}{9}x+\frac{2}{9}x+95=x\\\\\frac{2}{9}x+\frac{2}{9}x=x -95\\\\\frac{2}{9}x+\frac{2}{9}x-x=-95\\\\\frac{4}{9}x-x = -95\\\\\frac{4}{9}x-\frac{9}{9}x = -95\\\\\frac{-5}{9}x=-95\\\\x = -95*\frac{9}{-5}\\\\x=19*9$

x = 171

Number of boys = $\frac{2}{9}*171$ = 2 * 19 = 38

Number of girls = 38 + 95 = 133

Carlos earns $8 per hour for the first 40 hours that he works during a week. He earns $12 an hour for every hour he works over 4

mash [69]

Answer:

Hi there!

Your answer is:

$440 earned from working a 50 hour week

Step-by-step explanation:

8× 40= $320

Subtract 40 from 50 to determine how many overtime hours he worked!

12× 10 = $120

320+ 120= $440

I hope this helps!

Answer:

$Q(3\,min) = 0.349\,pd$

Step-by-step explanation:

The expression for the salt in the barrel is:

$Q(t) = 6\cdot (1-e^{-0.02\cdot t})$

The quantity of salt in the barrel after 3 minutes is:

$Q(3\,min) = 6\cdot [1-e^{-0.02\cdot (3\,min)}]$

$Q(3\,min) = 0.349\,pd$
