A triangle's measures are in the extended ratio of 2:4:9 find the measures of angles

Margaret [11]

Answer:

24°:48°:108°

Step-by-step explanation:

Since the sum of angles in a triangle is 180°, we can do 180÷15 to find the degree for 1 in the ratio. 180÷15 = 12.

12°×2 = 24°

12°×4 = 48°

12°×9 = 108°

The ratio is 24°:48°:108°

saul85 [17]

Answer:

$\frac{1}{12}$

Step-by-step explanation:

Given:

Gisselle has 1/2 of a candy bar.

She role off 1/2 of what she had and split it into three equal pieces.

Question asked:

What fraction of a candy bar was each piece?

Solution:

Gisselle has = $\frac{1}{2} \ of \ a \ candy \ bar$

She role off = $\frac{1}{2} \ of \ what\ she \ had$

$=\frac{1}{2} \ of\ \frac{1}{2}\\=\frac{1}{2} \times \frac{1}{2}\\\\=\frac{1}{4}$

As she split it into three equal pieces, we will divided it by 3, we get,

$\frac{1}{4} \div3\\\frac{1}{4}\times\frac{1}{3}$

$\frac{1}{12}$

Therefore, fraction of a candy bar of each piece is $\frac{1}{12}$

Fill in the blanks below regarding the end behavior of g(x) = -3x - 1. (3 pts each) On the left, the graph On the right, the gra

OLEGan [10]

Step-by-step explanation:

Step 1: Determine the end behavior

The left side of the graph goes to positive infinity in the y direction but negative infinity in the x direction.

$x$ → -∞

$f(x)$ → ∞

The right side of the graph goes to negative infinity in the y direction but positivie infinity in the x direction.

$x$ → ∞

$f(x)$ → -∞

How is graphing a two variable inequality similar to graphing a one variable inequality on the number line?

NISA [10]

There are several ways that it is similar.

1) You still shade on the parts that satisfy the inequality (even though it is 2 dimensional instead of 1.

2) You still need to show whether or not it is "greater than" or "greater than or equal to". On a line graph you use an open or closed dot, on a graph you use a dotted or solid line.
