Answer:
a = 86y
Step-by-step explanation:
Given:
Number of applicants per year = 86
Find:
Equation represent total applicants
Computation:
Assume;
Total number of years = y
Total number of applicants = a
So,
Total number of applicants = Number of applicants per year x Total number of years
a = 86 x y
a = 86y
Answer:
8/75
Step-by-step explanation:
make a table chart
divided 75 by 75 to get one then do it to the other side
8 divided by 75
will give you 8/75
Answer:
<u>15%</u> percent of the bill was her tip.
Step-by-step explanation:
Given:
Audrey gave a $0.90 tip to a waitress for serving a meal costing $6.00.
Now, to find the percent of the bill was her tip.
The bill was = $6.00.
The tip she gave = $0.90.
Now, to get the percent of the bill was her tip:
Therefore, 15% percent of the bill was her tip.
Answer:
129 degrees
Step-by-step explanation:
Ok, DAE, as given, is 90 degrees. So, BAD would equal 90 as well, so BAC would be 90-51, 39. And because FAE is vertical angle to BAC, FAE is also 39. So 39 + 90 is 129.
In order to solve for this question, let's assign a couple variables.
The variable 't' will represent the number of two-point questions, and the variable 's' will represent the number of six point questions.
From the given, we can already form two equations:
t + s = 36
("An exam... contains 36 questions")
2t + 6s = 148
("An exam worth 148 points... Some questions are worth 2 points, and the others are worth 6 points")
Before we begin calculating anything, we can simplify the second equation we made, since all the numbers are divisible by 2:
2t + 6s = 148
t + 3s = 74
Now let's refer back to the first equation. We can subtract both sides by 's' (you could also subtract both sides by 't', but I personally think that this will make solving the equation less difficult):
t + s = 36
t = 36 - s
This effectively gives us a value for the variable 't'. We can assign this value back into our first equation:
t + 3s = 74
(36 - s) + 3s = 74
36 + 2s = 74
2s = 38
s = 19
Input 's' into our second equation to solve for 't':
t = 36 - s
t = 36 - 19
t = 17
There are 17 two-point questions and 19 six-point questions
- T.B.
