Answer:

(15x-2)°+( 7x+4)°=90° --> 15x-2°+7x+4°=90° --> 22x+2°=90° --> 22x=90°-2° --> 22x=88° --> x=88/22 --> x=4.

m/_BAC=(15x-2)°=15×4-2 =58°

m/_CAD=(7x+4)°=7×4+4= 32°.

Answer:

1. $\frac{3}{8}$

2. $\frac{1}{4}$

3a. $-\frac{1}{4}$

3b. 3

3c. $-\frac{4}{5}$

4. $m = \frac{y_1 - y_2}{x_1-x_2}\\$

Step-by-step explanation:

Rises 6 inches for every horizontal change of 16 inches

Slope = rise/run

Slope = 6/16

Slope = 3/8

Rises 3 feet for every horizontal change of 12 feet

Slope = rise/run

Slope = 3/12

Slope = 1/4

3a.

$m = \frac{y_1 - y_2}{x_1-x_2}$

$m = \frac{3-2}{-2-2}$

$m = \frac{1}{-4}$

$m = -\frac{1}{4}$

3b.

$m = \frac{y_1 - y_2}{x_1-x_2}\\$

$m = \frac{-1 - 2}{-1-0}$

$m = \frac{-3}{-1}$

$m = 3$

3c.

$m = \frac{y_1 - y_2}{x_1-x_2}\\$

$m = \frac{1 - (-3)}{-1-4}\\$

$m = \frac{4}{-5}\\$

$m = -\frac{4}{5}$

$m = \frac{y_1 - y_2}{x_1-x_2}\\$

Answer:

1008 in

Step-by-step explanation:

Factor. x (squared)+3xy-54y (squared)

Alinara [238K]

$x^2+3xy-54y^2=x^2+9xy-6xy-54y^2\\\\=x\cdot x+x\cdot9y-6y\cdot x-6y\cdot9y\\\\=x(x+9y)-6y(x+9y)=\boxed{\boxed{(x+9y)(x-6y)}}$

Below are the solutions:
A)
Ohio: 8.23 * 10^5
US: 3.19 * 10^8

B)
(3.19 * 10^8)/(8.23 * 10^5) = 3.19/8.23 * 10^8/10^5
= 3.19/8.23 * 10^3 = 0.387606318 * 10^3
= 387.606318

The population of US is 387 times larger than that of Ohio's
