Answer:

Sample Response: The inequality could be t > 900. Draw a number line so it includes 900. Draw an open circle on 900. Shade all the numbers greater than 900, or to the right.

Step 1) Add 6 to both sides
Step 2) Divide both sides by 4

Following those steps above, you'll have this
4d - 6 < 18
4d - 6 + 6 < 18 + 6 .... applying step 1
4d + 0 < 24
4d < 24
4d/4 < 24/4 .... applying step 2
d < 6

So d can be any number that is less than 6. To graph this, we draw a number line, plot an open circle at 6 and shade to the left of the open circle. The open circle indicates to exclude the endpoint. The graph I'm describing is choice D

Answer: Choice D

Answer:

16. 60° from (180-120)°

17. 68° from (90-22)°

18. 80° from (180-100)°

19. 45° and 135°

20. 22.5° and 67.5°

Step-by-step explanation:

Supplementary angles add up to 180°

Complementary angles add up to 90°

For 19: let the angle be x

Then other angle is 3x

3x + x = 180°

4x = 180°

x = 45°

The other angle is 3x = (3×45) = 135°

For 20: let the first angle be m

Then the other angle is 3m

3m + m = 90°

4m = 90°

m = 22.5°

The other angle will be 3m = (3×22.5) = 67.5°

Beverly is driving up a hill at an incline of 45 degrees. She will travel 13 miles to reach the top. What is the height of the h

quester [9]

Answer:

The height of the hill is of 9.19 miles.

Step-by-step explanation:

Relations in a right triangle:

The sine of an angle is given by the measure of the opposite side divided by the hypotenuse.

The cosine of an angle is given by the measure of the adjacent side divided by the hypotenuse.

In this question:

Angle of 45º, and drives 13 miles. Due to the inclination, this represents the hypotenuse.

The height is the opposite side. So

$\sin{45} = \frac{h}{13}$

We have that $\sin{45} = \frac{\sqrt{2}}{2} = 0.71$

$\sin{45} = \frac{h}{13}$

$0.71 = \frac{h}{13}$

$h = 13*0.71 = 9.19$

The height of the hill is of 9.19 miles.
