Answer: 55% of the students passed the math test
Step-by-step explanation: The fraction represents the number of students who passed the math test out of all the students that took the test.
To find out what percent of the students that took the math test passed, we can turn the fraction into a percent.
To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. So to write as a percent, we need to find a fraction that is equivalent to
with a 100 in the denominator. We can do this by setting up a proportion.
Now, we can use cross products to find the missing value.
4,400 = 80n
÷80 ÷80
55 = n
Therefore, 55% of the students that took the math test passed it. This should make sense because 40/80 would be half and 44 students is only a little over 50%.
Answer:
B. x = 62 because 147 – 85 = 62 and 85 + 62 = 147
Step-by-step explanation:
We are given that
Exterior angle=
We have to find the value of x.
We know that
Exterior angle=Sum of opposite interior angles of triangle
Using the property
Subtract 85 from both sides we get
Option B is true.
B. x = 62 because 147 – 85 = 62 and 85 + 62 = 147
