There are 30 students in an art class. Fourteen of the students are girls.

1 answer:

DedPeter [7]3 years ago

8 0

Answer: B

Step-by-step explanation: To get the boys part of the ratio you will have to subtract 30 students and 14 students that are girls because all together there are 30 students and since we only know that 14 of them are girls that leaves the rest of the students boys. 30 - 14 = 16 so now we know how many boys there are. 16:14 can be reduced by 2 and that equals to 8:7.

Hope this helps!

The cost of a customer smartphone bill can be modeled by the equation c=10g+50

Vika [28.1K]

Answer:

c=10(g+5)

Step-by-step explanation:

Given that,

The cost of customer smartphone bill is given by the equation as follows :

c=10g+50

Where

g is the number of gigabits of data the customer per month

We need to factor this cost polynomial

The common between 10 and 50 is 10

Taking 10 common. So,

c=10(g+5)

Hence, the required factor is equal to c=10(g+5).

Complete the inequality.<br> (-9/8)/(-2 3/4) ? 3/22<br> ><br> <<br> =

Thepotemich [5.8K]

Answer:

(-3/8)/(-2 3/4) = 3/22

Step-by-step explanation:

Solve the following;

$\frac{\left(-\frac{3}{8}\right)}{\left(-2\frac{3}{4}\right)}$

$=\frac{\left(-\frac{3}{8}\right)}{\left(-\frac{11}{4}\right)}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{-b}=\frac{a}{b}$

$=\frac{\frac{3}{8}}{\frac{11}{4}}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}$

$=\frac{3\cdot \:4}{8\cdot \:11}$

$\frac{3}{22}$

Thus, $\frac{\left(-\frac{3}{8}\right)}{\left(-2\frac{3}{4}\right)}$ = $\frac{3}{22}$
