Given:

Four lines are marked proportion, the length of TW can be determined by

$TW=a+4+b$

Value of a:

Let us set the proportion for the given lines.

Thus, we have;

$\frac{a}{7}=\frac{4}{5}$

$5a=28$

$a=5.6$

Thus, the value of a is 5.6

Value of b:

Let us set the proportion for the given lines.

Thus, we have;

$\frac{4}{5}=\frac{b}{5}$

$20=5b$

$4=b$

Thus, the value of b is 5.

Length of TW:

The length of TW is given by

$TW=5.6+4+4$

$TW=13.6$

Thus, the length of TW is 13.6

An after-school care facility tries to maintain a 2-to-1 ratio of children to adults. If the facility hired five adults, what is

astra-53 [7]

Answer:

10 children

Step-by-step explanation:

If we have a ratio of 2:1 children:adults, then we can find out how many children max can enroll if there are 5 adults.

Our original ratio was 2:1 and now it's x:5, assuming x is the number of children enrolled. We multiply 1 by 5 to get to 5, so we need to multiply 2 by 5 to get the total number of chlidren.

2 × 5 = 10

Hope this helped!

Given that f(x) = 2x + 5 and g(x) = x − 7, solve for f(g(x)) when x = −3.

Gnesinka [82]

F(x)=2x+5, g(x)=x-7

f(g(x))=2(x-7)+5=2x-14+5=2x-9

When x= -3:

$2\cdot (-3)-9=-6-9=\boxed{-15}$
