Rosa can run 3 miles in 42 minutes. As you can see in the work above, by using a proportion and solving it you can find the answer.
Answer:
the sum of all three angles is 180° in every plane triangle.
knowing that we know that the upper right angle is 180-99-37 = 44
do it follows:
-x-5 = 44
and
-x = 49
and there
x is -49

The sample proportion is a point estimate of the population proportion. Therefore we need to convert the given percentage to a decimal fraction to find the best point estimate.
35/100 = 0.35
The best point estimate is 0.35.
Answer:
There were 40 2-point questions and 9 3-point questions.
Step-by-step explanation:
To solve this situation, write two equations. One for the number of questions and one for the number of points.
Let x be the number of 2 point questions.
Let y be the number of 5 point questions.
x + y = 49
Now since x are each worth 2 points, the total points is 2x.
And since y are each worth 5 points, the total points is 5y.
So 2x + 5y = 125. Substitute one of the equations into the other to solve for the variables.
x + y = 49 becomes x = 49 - y. Substitute it.
2(49-y) + 5y = 125
98 - 2y + 5y = 125
98 + 3y = 125
3y = 27
y = 9
Substitute y = 9 back into the equation x = 49 - y to find x.
x = 49 - 9
x = 40
