What is the area of a circle with a radius of 7 cm? (Use 3.14 for Pi and round to the nearest tenth.)
38.5 centimeters squared
44.0 centimeters squared
150.0 centimeters squared
153.9 centimeters squared

Answer:

e

Step-by-step explanation:

Answer:

1. c

2. c

Step-by-step explanation:

1. subract 8 from both sides to get b/-4=-3

multiply both sides by -4 to isolate b

you get b=12

2. combine like terms 3c-4=-8+2c

add 4 to both sides: 3c = -4+2c

subtract 2c from both sides

c=-4

Answer: 50

Step-by-step explanation:

5/9 (f-32) if f = 122 you take 122 and subtract 32 because of order of operations and now you have 5/9 (90) and then you multiply 5/9 times 90 and you get 50

Answer:

D

Step-by-step explanation:

So when looking at this problem, its important to note that your X is your horizontal axis, and your Y is your vertical axis. So when moving left or right, you want to look at the x, so generally adding to X moves the point to the right, and subtracting from x moves the graph to the left. So for X, because you are looking at moving 1 unit to the right, you are going to want to add 1 (x+1), Then since y is your vertical axis, this will be your up or down factor. So its very similar if you are adding to y, you are moving up, but if you are subtracting from y, you are moving down.  Therefore your final answer will be (x+1, y-4)

Step-by-step explanation:

Answer:

20

Step-by-step explanation:

Step-by-step explanation:

step 1. V = LWH. L = length. W = width. H = height.

step 2. V = (912)(312)(612) = 174,140,928 in^3.

The volume of Maria's new fish tank is 174,140,928 cubic inch.

It is required to find  the volume of Maria's new fish tank.

In geometry, a cuboid is a solid shape or a three-dimensional shape. A convex polyhedron that is bounded by six rectangular faces with eight vertices and twelve edges is called a cuboid.

Given :

Maria has a new fish tank for her goldfish.

The fish tank is in the shape of cuboid.

length=912 inches

width=312 inches

Height=612 inches

Part A

The formula of volume of her new fish tank

Volume=length ×width × height.

Part B

Volume=length ×width × height.

By the use of formula we have,

V = (912) ×(312) ×(612)

V= 174,140,928 cubic inch.

Therefore, the volume of Maria's new fish tank is 174,140,928 cubic inch.

Answer: 160 songs.

Step-by-step explanation:

75% hip hop music   -    120 songs

100% all music          -     x songs

Let's write the proportion:

[tex]\dfrac{120}{75} =\dfrac{x}{100} \\\\75x=120 \cdot 100\\75x=12000\\75x : 75 = 12000 : 75\\x = 160[/tex]

Thus, Landon have 160 songs in his music library.

Answer:

There are 10 counters in the bag and you want the 4

As their is only one for the probability is

1/10

There are now 9 counters left in the bag.

You only want the even ones , which are 2 6 8 and 10 ( four has been taken out)

There are only four even counters in the bag of nine counters so the probability is

4/9

As you want both of these to occur, you need to multiply them

1/10 x 4/9 = 49/90

Step-by-step explanation:

The probability of getting a multiple of 3 both times is 2/30.

The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.

Given:

We are randomly picking two numbers from 1-10.

Multiple of 3 between 1 and 10 are 3, 6, 9.

To find the probability:

Here, we are considering the that the numbers are chosen without replacement.

The probability of getting a multiple of 3 both times,

= 3/10 x 2/9

= 6/90

= 2/30

Therefore, the probability is 2/30.

Determine the radius of a circle. ...

Substitute this value to the formula for circumference: C = 2 * π * R = 2 * π * 14 = 87.9646 cm .

You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm² .
