Answer:

90pi

Step-by-step explanation:

SA = pi r l +B

we know the radius is 5

We need to find the slant height using the Pythagorean theorem

a^2+b^2 = c^2

5^2+12^2 = l^2

25+144= l^2

169 = l^2

Taking the square root of each side

sqrt(169) = sqrt(l^2)

13 = l

B is the area of the base

B = pi r^2 = pi (5)^2 = 25 pi

SA = pi r l +B  = pi (5)*13 + 25pi

                       =65pi +25pi = 90pi

Answer:

90 pi

Step-by-step explanation:

Just in case the other answer was confusing. Just put it in, and it marked it right. 90 is the answer

SA= 90

Answer:

(-11, -7)

Step-by-step explanation:

The original point is (-9,-2)

The transformation you have to do is (x-2 , y-5)

This makes it so that you move the original point 2 units to the left (as a negative sign in the x value is towards the left side where the negative units are) and 5 units downwards (as a negative sign in the y value is on the negative side of the y-axis which is down)

So, your final answer would be (-9-2,-2-5) which is (-11,-7)

Answer:

15

Step-by-step explanation:

Multiply: 25x.60=15

The reason why you multiply 25 times .60 is because you need to change the percentage to a decimal. The way you change you from a percentage to a decimal is by moving the decimal twice to the left.

So, 60%=.60

Answer:

10

Step-by-step explanation:

take your total and multiply it by the percentage.

40 × .75 = 30. he attended 30 meetings. take your total and subtract your new value.

40 - 30 = 10 meetings not attended

Answer:

16 is correct

Step-by-step explanation:

Answer:

x=1.25 and y=-5.5

Step-by-step explanation:

2x+y=-8, 2x=-y-8 or 4x=-2y-16. Plug this value in the second equation, we have - 2y-16-2y=6, y=-5.5. Plugging this in any equation we have, x=1.25

Answer:

x = 13 cm

Step-by-step explanation:

The figure given is a square.

Area of the given square (A) = 169 cm²

Formula for area of a square is:

A = s²

Where,

s = x

Thus:

169 = x²

Take the square root of both sides

√169 = √x²

13 = x

x = 13 cm

Answer:

Sin 60=y/46

y=39.8

-39.8^2+46^2=x^2

X=23

So y=39.8 and x=23

Answer:

I think it is the first one NOQ AND MLJ

Answer:

Then it is just a matter of plugging in the values into the formula. For example, if one base is 6 cm long, the other is 10 cm long and the height is 4 cm, the area is then (6 + 10) / 2 x 4 = 16 / 2 x 4 = 8 x 4 = 32 cm 2 (32 square centimeters).

Answer:

2(21/pi)=d

Step-by-step explanation:

The formula for a circumference is C=2(pi)(r) in this case we know our circumference is 42 meters so 42=2(pi)(r), we must leave our radius by itself so we divide by 2 to get 21=pi(r) we then also divide by pi which will get us 21/pi=r and we know that the diameter is double of the radius so we just double which will then be 2(21/pi)=d

Answer:

20, 20, 21, 22, 23, 23, 24, 24, 25, 25, 26, 26

Step-by-step explanation:

median (middle number) is (23 + 24) / 2 = 47/2 = 23.5 <== median

Q1 = (21 + 22) / 2 = 43/2 = 21.5 <== lower quartile

Q3 = (25 + 25) / 2 = 50/2 = 25 <== upper quartile

Answer:

  1/8

Step-by-step explanation:

To find out, divide 1/3 by 8/3.

  (1/3)/(8/3) = 1/8

8/3 goes into 1/3 exactly 1/8 times.

__

There are (at least) two ways to divide fractions.

1. "invert and multiply" (A.K.A. "swap dot")

  [tex]\dfrac{1}{3}\div\dfrac{8}{3}=\dfrac{1}{3}\cdot\dfrac{3}{8}=\dfrac{1\cdot3}{3\cdot8}=\boxed{\dfrac{1}{8}}[/tex]

__

2. Drop common denominators.

  [tex]\dfrac{1}{3}\div\dfrac{8}{3}=1\div8=\boxed{\dfrac{1}{8}}[/tex]

Answer:

1296

Step-by-step explanation:

9 x 144

A square foot is a unit of area. It is the size of a square that is one foot on a side. It is 144 square inches, 1/9th of a square yard, or approximately 0.093 square meters.

A square inch is a unit of area. It is the size of a square that is one inch on a side. It is 1/144th of a square foot, or exactly 6.4516 square centimeters.

So, 9 x 144 = 1296
