Answer:
To see if multiple ratios are proportional, you can write them as fractions, reduce them and compare them. If the reduced scores are all the same, you have a proportion.
Answer: angel 2 is 70
And angle 5 is 30
Step-by-step explanation:
Angle 2 is 70 because it right across from each other so they are equal
Angle 5 is 30 because everything at the end has to add to 100 so it would make it 30. (I’m not quite sure on this on but 30 is my best guest)
70+30=100
Answer:
C. there are no solutions because the slopes are the same and the y-intercepts are different.
step-by-step explanation:
y = 2/3x - 6
3y - 2x = 9
y = 0
3(0) - 2x = 9
-2x = 9
/-2 /-2
x = -9/2 = -4.5
x = 0
3y - 2(0) = 9
3y = 9
/3 /3
y = 3
(-4.5, 3)
slope 2/3
y-intercept (0, 3)
there are no solutions because the slopes are the same and the y-intercepts are different
It is given in the problem that in 1975, the number of restaurants chain is 15,250.
It is also given in the problem that 2000, the total number of restaurants is 21, 655. Therefore, the solution is is shown below:
% increase= ((# of restaurants is year 2000 - # of restaurants in year 1975)/number of restaurants in year 2000) * 100
% increase = (21,655-15250)/21,655 *100
% increase = 29.58%
Answer is 29.58%
