Answer:

4.2

Step-by-step explanation:

cos65°= adj/hyp

cos65°= x/10

x= cos65° * 10

*make sure your calculator is in degree mode

Cos = adjacent / hypotenuse

cos 65 = x/10

10 cos 65 = x

x = 4.22618....

x = 4.2 (nearest tenth)

A type of green paint is made by mixing 2 cups of yellow with 35 cups of blue.

adell [148]

Answer:

1. 1 cup of yellow 17.5 cups of blue 2. 4 cups of yellow 70 cups of blue

3. 2 cups of yellow 40 cups of blue 4. 2 cups of yellow 30 cups of blue

Step-by-step explanation:

1. to get same shade keep ratios the same but divide by 2 for smaller amount

2/2 = 1 and 35 /2 = 17.5

2. similar to 1. except multiply by 2

3. use same yellow amount but more blue

4. use same yellow but less blue

The table below shows the surface area y, in square feet, of a shrinking lake in x days:

andreyandreev [35.5K]

Based on the data, the most likely correlation coefficient would be -1.
The slope between 20 and 30 days is -1, and it represents the change in the surface area of the lake per day.
The data represents correlation, not causation.

Since the data would form a perfectly straight line through the points, the correlation coefficient would be -1 for a perfect decreasing fit.
To find the slope, find the change in the surface area between those days, the change in the days, and write it as surface area/days: 80-90=-10; 30-20=10; -10/10=-1
This is not causation because there could be lurking variables we cannot see.

Solve the inequality for x. Show each step of the solution.<br> 16x > 12(2x – 6) – 24

Dafna11 [192]

You want to start this problem by handling the parentheses and distributing the 12.
So 16x > 12(2x - 6) - 24 would become...
So 16x > 24x - 72 - 24
Next you would combine like terms...
So 16x > 24x - 96
Then to get rid of the negative you would add 96 to both sides...
So 16x + 96 > 24x
After that you would subtract 16x from both sides...
96 > 8x
Lastly, divide by 8 to get x.
12 > x

Is (-5, 8)a solution for y-2x>17?

Gnoma [55]

You can plug in the numbers to check.
Y - 2x > 17
(8) -2(-5) > 17
8 + 10 > 17
18 > 17
This is true so
Final answer:
Yes, (-5,8) is a solution
