the answer to this question is -7.25 or 7 1/4
You can see that every decade the income increases by 6,250. So if you want to do 5 years instead you would have to add 3,125 to the income of 1980 to find what the income was for 1985. Now you add 33,750+3,125= 36,875. The financial aid cutoff for 1985 would be $36,875.
Answer:
924 teenagers
Step-by-step explanation:
154 / 500 ×3000
= 924
Since 154 teenagers out of 500 prefer action movies, you'll just divide them by their total number 500 multiplied by the other total number 3000 to get the others who prefer action movies.
trying the others too
sci- fi
116 / 500 × 3000
= 696
romance
109 / 500 × 3000
= 654
comedy
78 / 500 × 3000
= 468
drama
43 / 500 × 3000
= 258
putting all of them together should give u ur total number
924 + 696+ 654 + 468 +258
= 3000
Answer:
55 degrees and 125 degrees
Step-by-step explanation:
Supplementary means that they add up to 180.
x + y = 180
Let's let x be the larger angle.
x = 15 + 2y
The above equation comes from the information given, that it's 15 more than twice the smaller angle.
Now let's use substitution.
x + y = 180
(15 + 2y) + y = 180
15 + 3y = 180
3y = 165
y = 55
The smaller angle is 55. Plug this back in to the first equation to get x.
x + y = 180
x + 55 = 180
x = 125
Now that you have both, test them again just to be sure that they fit the given conditions.
Answer:
16/25
Step-by-step explanation:
Given
Number of green marbles = 9
Number of White marbles = 17
Total number of marbles = 26
Probability of picking a white marble = 17/26
When a white marble is picked without replacement,
Probability of picking another white marble after first picking a white marble
= 16/25
= 0.64
This is because the total number of marbles would have reduced from 26 to 25 and the number of white marbles from 17 to 16.
