Each of four test scores in Connie’s class is to be weighted equally. On the first three tests, Connie scored 80%, 90% and 95%. What percent must she score on her fourth test to have an overall average of exactly 90%?

Answers

Answer 1

Answer:

95%is the answer

Step-by-step explanation:

Answer 2

Answer:

95%

Step-by-step explanation:

We can use the balancing method to do this.. first what is the total below 90?

The total is 10% because 90-80 which was the only percentage below 90 is 10%. Then, what is the total above 90?

The total is 5% because the only percentage above 90 is 95 and 95-90 is 5%

Now we use the balancing method to get from 5-10.

Using the balancing method we get 95%

What is a word problem?

A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

For the given situation,

Harold cut 18 and a half inches off a rope that was 60 inches long.

Let the remaining length of the rope be x.

This can be written as,

⇒ [tex]x=60-18.5[/tex]

⇒ [tex]x=41.5[/tex]

Hence we can conclude that the length of the remaining rope is 41.5 inches.
