Answer:

93

Step-by-step explanation:

The mean of a list of numbers is the sum of the numbers divided by the count of the numbers in the list.

In this case, representing the eighth score with x, the mean is (611+x)/8

Solving for the mean:

88=(611+x)/8

Multiply both sides by 8

8*88=611+x

704=611+x

704-611=x

x=93

The radius of a wheel is 21m.how much distance will it covers when it rotates 5 times?​
mrs_skeptik [129]

Answer:

Distance = 660 meters

Step-by-step explanation:

Given the following data;

Radius, r = 21 m

Number of revolutions = 5 times

To find the distance covered;

The distance covered in one revolution is given by the circumference of a circle.

Mathematically, circumfeence of a circle is equal to;

C = 2πr

Substituting into the formula, we have;

C = 2 * 22/7 * 21

C = 44 * 3

C = 132 meters

Next, we find the distance covered;

Distance = Circumference * Number of revolutions

Distance = 132 * 5

Distance = 660 meters

Write the equation - 3x + 2y = 7 in slope-intercept form.
VikaD [51]

Answer:

The answer is :

y =  \frac{3}{2} x +  \frac{7}{2}

Step-by-step explanation:

Given that the slope-intercept form is represented by y = mx + b. So you have to rearrange the equation :

- 3x + 2y = 7

2y = 3x + 7

y =  \frac{3}{2} x +  \frac{7}{2}

Since BC is parallel to DE, triangles ABC and ADE are similar. What are the lengths of the unknown sides?
polet [3.4K]

Answer:

Since we have BC ║ DE, we know that:

AB/AD = BC/DE

12/(12 + 4) = BC/12

12/16 = BC/12

BC = (12 · 12)/16 = 9 (in)

Applying the pythagorean, we have:

AB² + BC² = AC²

12² + 9²     = AC²

225           = AC²

AC             = √225 = 15 (in)

Using the information about the parallel lines again, we have:

AC/CE = AB/BD

15/CE = 12/4

CE = (15 · 4)/12 = 5 (in)

So the answer is B
