Rob's first four test scores are 80, 85, 100 and 85. What does he have to score on the last test in order to have a test average of 90?

Answers

Answer:

100

Step-by-step explanation:

85 +80+100+85+x(the unknown),/the number of numbers ie 5

350+x/5=90

350+x=90 * 5

350+x=450

x=450-350

x=100

The score on the last test in order to have a test average of 90 is 100.

Given that, Rob's first four test scores are 80, 85, 100 and 85.

We need to find the score on the last test in order to have a test average of 90.

What is an average?

By definition, an average is the arithmetic mean of the sum of all the values divided by the total number of values in a given set. An average is calculated for those sets of values which are more or less the same. The term average describes the numeric value that represents a large amount of data. An average can be derived by calculating the ratio of the sum of all the values to the number of units or values.

Let the score on the last test be x.

Now, average=(80+85+100+85+x)/5 =90

⇒350+x=450

⇒x=100

Therefore, the score on the last test in order to have a test average of 90 is 100.

A central angle of a circle measures π/3 radians.The length of the minor arc intercepted by this central angle is 7 inches. Find the length of the radius of the circle.

Answers

9514 1404 393

Answer:

  6.68 in

Step-by-step explanation:

The length of an arc is given by ...

  s = rθ . . . . θ in radians

Then the radius is ...

  r = s/θ

  r = (7 in)/(π/3) = 21/π in ≈ 6.6845 in

The radius of the circle is about 6.68 inches.

Answer:

Solution :-

Angle of circle = π/3 r

Length of minor arc = 7 in

Now

We know that

Radius = Length/Angle

Radius = 7/(π/3)

Radius = 7/π × 3

Radius = 21/π
