Answer:
21%
Step-by-step explanation:
Since both 100 and 79 is the percentage, you need to find how much has decreased, so you have to subtract.
100-79 = 21
So, 21% was decreased.

Answer:
X=60°
Y=50°
Step-by-step explanation:
Triangles must equal 180° when you add all angles together.
Triangle with angle X
50+70=120180-120=60X=60°To find the value of Y takes a few more steps, but it isn't hard!
Angle Y is on a line, which equals 180° just like a triangle.
We know X=60°, but we don't know what the blank angle equals.
We use the same steps as we did when finding X
60+50=110180-110=70Blank angle=70°We know that the blank angle=70° and that X=60°
Since the line equals 180, we add the two angles and then subtract from 180, just like before!
70+60=130180-130=50 Y=50°What do you do to find the power of a power?

2. A ball is drawn at random from a box containing 6 red balls , 4 white balls and 5 blue balls.
Determine the probability that is red or white.
Answer:
1. 0.2222222
2. .6667
Step-by-step explanation:
for question 1
there can only be 36 outcomes so you find out how many time you could get 7and2 which is 8 from so u write 8.36=.2222
for question 2
divide the outcome by the total out comes example(there are 6 red balls and 4 white out of 15 so you do 10/15=.6667)

Jayson gets a loan from his parents with no interest L represents the remaining amount Jayson owes his parents on his loan t months. L=-250t+7000 how much did Jayson borrow from his parents?
Answer:
7000
Step-by-step explanation:
Given the equation :
L=-250t+7000
L = amount owed after t months of repayment.
From the equation given, we could deduce that it is a linear equation of the form :
y = bx + c
Where, b = - 250 is the slope = fixed amount paid per month and it's negative because the amount owed will reduce with each payment made.
c = intercept, which is the value of L when t = 0
This will give amount borrowed :
L=-250t+7000
At t = 0
L = - 250(0) + 7000
L = 7000

what is y% of 8 is .248
Find the measure of angle N in the triangle . first find the value of y and then plug it in. please show work. help
Answer:
Step-by-step explanation:
By the Isosceles Triangle Theorem, angle O and angle M are congruent because the sides across from each of these angles are congruent. therefore, O = M = 4y - 15. Since, by the Triangle Angle-Sum Theorem all the angles of a triangle have to add up to equal 180 AND angle O and angle M are the same:
7y + 4y - 15 + 4y - 15 = 180 and
15y - 30 = 180 and
15y = 210 so
y = 14. Plug 14 in for y in 7y and get that
∠N = 98°
