you roll a fair number cube twice. What is the probability of rolling two 3's if the first roll is a 5? Expain

1 answer:

6 0

Well if you row the 1st time and get a 5 and only get to role 2 times the probability of rowing two 3's is half because if you get 1 3 outta 2 rolls that's the 50% chance but lets not for get the 1/6 chance of getting a 3 in the 1st place hope this helps

9. A rectangle has a width that is 2 feet longer than four times the length. What is the length of the rectangle

Bad White [126]

Answer:

6 feet

Step-by-step explanation:

Perimeter = 2L + 2W

Since you know the perimeter is 64 feet, you would plug that into the perimeter side.

64 = 2L + 2W

You also know the width is 2 feet longer than 4 times the length.

64 = 2L + 2(2 + 4L) ----> Multiply 2 * 2 and 2 * 4l

64 = 2L + 4 + 8L ----> Subtract 4 from each side

-4 -4

60 = 2L + 8l ----> add these two

60 = 10L

/10 /10 -----> divide by 10 on each side

6 = L

Now that we know the length, find the width.

64 = 2(6) + 2(2 + 4(6)) -----> multiply 2 * 6 and 4 * 6

64 = 12 + 2(2 + 24) -------> add 24 and 2

64 = 12 + 2(26) -------> multiply 2 and 26

Before you go any further, you now know that the width is 26 feet. Continue solving.

64 = 12 + 52

64 = 64

Everything checks out.

The length is 6 feet and the width is 26 feet.

hree vertices of a triangle are located at A (4, 3), B (2, 1), and C (3, 4). Which shows the correct graph of the vertices? A. A

bagirrra123 [75]

Answer: Choice A

Point A is plotted 4 units to the right and 3 units above the origin. Point B is plotted 2 units to the right of and 1 unit above the origin. Point C is plotted 3 units to the right and 4 units above the origin

====================================================

Explanation:

The point A(4,3) means we start at the origin and move 4 units to the right and 3 units up. The x and y axis are separate number lines to mark a location

B(2,1) means we move 2 units to the right and 1 unit up

C(3,4) means we move 3 units to the right and 4 units up

Each time we plot a new point, we always start at the origin.
