Area= π • r^2

Diameter= 10 ÷ 2
Radius= 5

Area= π • 5^2
Area= 25π

Answer is Area= 25π

or 25 • π = 78.54= Area

A bag contains 8 red marbles, 3 blue marbles, and 1 green marble. Find P(not blue). a. 9 c. One-fourth b. Four-thirds d. three-f
gayaneshka [121]

In order to find the probability of drawing a marble that is NOT BLUE, we must find the ratio of non-blue marbles to the total amount of marbles

Let's count how many marbles total there are first

8 red + 3 blue + 1 green = 12 marbles total

Now, how many marbles are there that <u>ARE NOT BLUE </u>

8 red + 1 green = 9 marbles <u>THAT ARE NOT BLUE </u>

Now<em> let's create a ratio</em> to find a probility

9/12

This can be simplified to 3/4 by taking out the common factor of 3

Your answer is D! "three-fourths"

Are the lines parallel, perpendicular, or neither? One line through the points (3, 2) and (6, 8), and another line through the p
Temka [501]

Answer:

Parallel.

Step-by-step explanation:

Let's find the slope of each line.

One through the points (3,2) and (6,8):-

Slope = rise / run = (8-2)/(6-3)

=  6/3 = 2

The other line:-

Slope =  (6-2)(2-0)

= 4/2 = 2

The slopes are the same so the 2 lines are parallel.

A rectangular metal plate is measured to be 7.6cm long and 3.1cm wide, both correct to one decimal place.
ElenaW [278]

Answer:

We know that the rectangular plate has measures of:

length = 7.6 ± 0.05 cm

width = 3.1 ± 0.05 cm

(the error is 0.05cm because we know that both measures are correct to one decimal place)

First, the upper bound of the length is equal to the measure of the length plus the error, this is:

L = 7.6 cm + 0.05 cm = 7.65 cm

The upper bound of the area is the area calculated when we use the upper bound of the length and the upper bound of the widht.

Remember that the area for a rectangle of length L and width W, is:

A = W*L

Then the upper bound of the area is:

A = (7.6cm + 0.05cm)*(3.1cm + 0.05cm) = 10.8 cm^2
