Need help figuring out the values of x and y for 14-16 please!!

bezimeni [28]

14.

y = 75, its a vertical angle to 75.

x = 75, its a vertical angle to 75, or alternate interior angle to 75.

15.

y = 74, its a supplementary angle with 106.

x = 106, its a corresponding angle to 106.

16.

y = 90, its a supplementary angle with x.

x = 90, its a corresponding angle with 90.

Carmela saves 8% of her weekly earnings. She earned $25 last week. How

BabaBlast [244]

Answer:

Step-by-step explanation:

So, 8% is the same as 8/100 or .08. I'll be using .08 to make things more simple. Now, if she earned $25 last week and she saves 8% of it then, the equation to find how much she saved would be 25 times .08. Simply plug that into a calculator to get the answer $2.

viktelen [127]

Answer:

$y=11,600x+6,000$

Yearly sales in 1990: $98,800.

Step-by-step explanation:

We have been given that the sales of a certain appliance dealer can be approximated by a straight line. Sales were $6000 in 1982 and $ 64,000 in 1987.

If at 1982, $x=0$ then at 1987 x will be 5.

Now, we have two points (0,6000) and (5,64000).

$\text{Slope}=\frac{64,000-6,000}{5-0}$

$\text{Slope}=\frac{58,000}{5}$

$\text{Slope}=11,600$

Now, we will represent this information in slope-intercept form of equation.

$y=mx+b$ , where,

m = Slope,

b = Initial value or y-intercept.

We have been given that at $x=0$ , the value of y is 6,000, so it will be y-intercept.

Substitute values:

$y=11,600x+6,000$

Therefore, the equation $S=11,600x+6,000$ represents yearly sales.

Now, we will find difference between 1990 and 1982.

$1990-1982=8$

To find yearly sales in 1990, we will substitute $x=8$ in the equation.

$S=11,600(8)+6,000$

$S=92,800+6,000$

$S=98,800$

Therefore, the yearly sales in 1990 would be $98,800.

72 is what percent of 45?

marysya [2.9K]

72 is 160% of 45. The reason it is like that is because you make it a fraction, so 72/45. And that tells you that 72 is 1.6 times the amount of 45. That means that 72 is 160 % of 45
