Answer is 273.1

Find the area of the two semi circles by just finding the area of them combined because they are two identical semi circles, their area can be found using the formula a= πr^2
Then just multiply 9 x 8 and add them.

What is the probability that a randomly drawn marble from bag is green. Given that it is not red?

tatiyna

Answer:

The probability is 0.2, or 20%.

Step-by-step explanation:

A probability is the ratio of the number of relevant outcomes and the number of all possible outcomes. If we know that the marble drawn is not red, the number of possible outcomes N is

N = (number of blue marbles) + (number of green marbles) = 25

and the number of relevant outcomes (marble being green) is n:

n = (number of green marbles) = 5

So, the probability is

P = n / N = 5 / 25 = 1 / 5 or 0.2, or 20%

Why is the value of q?

Rudiy27

Given:

QSR is a right triangle.

QT = 10

TR = 4

To find:

The value of q.

Solution:

Hypotenuse of QSR = QT + TR

= 10 + 4

= 14

Geometric mean of similar right triangle formula:

$\frac{\text { hypotenuse }}{\text { leg }}=\frac{\text { leg }}{\text { part }}$

$$\Rightarrow \frac{14}{q} =\frac{q}{4}$

Do cross multiplication.

$$\Rightarrow14\times 4 =q\times q$

$$\Rightarrow 56 =q^2$

Switch the sides.

$$\Rightarrow q^2 =56$

Taking square root on both sides.

$\Rightarrow q =2 \sqrt{14}$

The value of q is $2 \sqrt{14}$ .

Factor -1/8 out of -1/8y + 24

romanna [79]

$-\frac{1}{8}y+24$

To factor -1/8 out you need to find a number that multiply by -1/8 be equal to each term in the expression.

To find those numbers you divide each term into -1/8:

$\begin{gathered} \frac{-\frac{1}{8}y}{-\frac{1}{8}}=y \\ \\ \frac{24}{-\frac{1}{8}}=-24\cdot8=-192 \end{gathered}$

Then, the factors are:

$-\frac{1}{8}y+24=-\frac{1}{8}(y-192)$
