Maggie wants to have a 94 average in science class. Her last 5 test grades were 95, 98, 89, 92, and 94. What score does Maggie need to get on her last science test in order to have a 94 as her final average?

A - 94
B - 95
C - 96
D - 97

C. 96

Step-by-step explanation:

95 + 98 + 89 + 92 + 94 + 96 = 564

564/6 = 94

C.) 96

Step-by-step explanation:

First of all, to find the average you need to add up the values given then divide the total by the number of values. Since we already have some of the values given which are 95, 98, 89, 92, and 94, we're going to add them up. Once you add them, you should get a total of 468. Now, we add another value that is in the answer choices because we're figuring out what Maggie needs to score on her science test to get a 94 as her final. We then would add 94 to the total which should give us 562. Next, we divide 562 by however many values we have which is 6. Once the total is divided by 6, the quotient should be 93.666 As you can see, it doesn't give us 94, thus making A not the correct answer. You will continue to do this with the other answer choice questions until you get 94.

Here is a less wordy way to find the

1.) Add up the values given

2.) Pick an answer choice and add the value to the total

3.) Divide by however many values are there

4.) Continue this until you find the correct answer

95 + 98 + 89 + 92 + 94 = 468

Pick an answer choice

468 + 96 = 564

Count the total values, including the answer choice

564 ÷ 6 = 94

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
