The area will be
2500(1-5.25/100)^15
=1113km2 (nearest square kilometer)

SVEN [57.7K]

<u><em>Answer:</em></u>

Radius of the ball is approximately 6.5 cm to the nearest tenth

<u><em>Explanation:</em></u>

The ball has the shape of a sphere

<u>Surface area of a sphere can be calculated using the following rule:</u>

Surface area of sphere = 4πr² square units

<u>In the given problem, we have:</u>

Surface area of the ball = 531 cm²

<u>Substitute with the area in the above equation and solve for the radius as follows:</u>

$531 = 4\pi r^2\\ r^2=\frac{531}{4\pi } = 42.255 \\ \\ r=\sqrt{42.255}=6.5004 cm$ which is approximately 6.5 cm to the nearest tenth

Hope this helps :)

An interior painter is painting a wall that is 8 feet by 14 feet. He needs to determine how much paint he will need for the job.

So if you do 8x14=112 is the area. So 112 divided by 40= 2.8. He will need 2.8 pints of paint.

Komok [63]

Answer:

i think the answer is (B)

Step-by-step explanation:

The y value of a point where a vertical line intersects a graph represents an output for that input x value. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output.

5m + 3 ( 8m +7 ) +4^2<br><br> Can someone help me

Pie

Answer:

29m+37?

Step-by-step explanation:

<em>Pemdas</em>

5m+3(8m+7)+4^2

Parentheses first: 5m+24m+21+4^2

Exponents next: 5m+24m+21+16

No multiplication or division so addition is last:

29m+37

These two can't add together because one has a variable.

Two dice are numbered 1,2,3,4,5,6 and 1,1,2,2,3,3 respectively. They are rolled and

Alexxx [7]

Answer:

P(2) = 1/18

P(3) = 1/9

P(4) = 1/6

P(5) = 1/6

P(6) = 1/6

P(7) = 1/6

P(8) = 1/9

P(9) = 1/18

Step-by-step explanation:

Each die has six possible outcomes, so both dice together have 6*6 = 36 outcomes:

(1,1), (1,1), (1,2), (1,2), (1,3), (1,3),

(2,1), (2,1), (2,2), (2,2), (2,3), (2,3),

(3,1), (3,1), (3,2), (3,2), (3,3), (3,3),

(4,1), (4,1), (4,2), (4,2), (4,3), (4,3),

(5,1), (5,1), (5,2), (5,2), (5,3), (5,3),

(6,1), (6,1), (6,2), (6,2), (6,3), (6,3).

The sum of the values for each outcome is:

2, 2, 3, 3, 4, 4,

3, 3, 4, 4, 5, 5,

4, 4, 5, 5, 6, 6,

5, 5, 6, 6, 7, 7,

6, 6, 7, 7, 8, 8,

7, 7, 8, 8, 9, 9.

To find the probability of each sum, we just need to divide the number of times this sum appears over the total number of possibilities (36), so we have:

P(2) = 2/36 = 1/18

P(3) = 4/36 = 1/9

P(4) = 6/36 = 1/6

P(5) = 6/36 = 1/6

P(6) = 6/36 = 1/6

P(7) = 6/36 = 1/6

P(8) = 4/36 = 1/9

P(9) = 2/36 = 1/18
