What is the probability that I will randomly pick a 2, put it back, then randomly pick a 4?

Answers

Answer: [tex]\frac{1}{9}[/tex]

Step-by-step explanation:

The probability that you get a 2 is [tex]\frac{4}{52}[/tex] and that simplifies into [tex]\frac{1}{3}[/tex]. It is the same probability that you get a 4 because you put the 2 back. [tex]\frac{1}{3}[/tex] x [tex]\frac{1}{3}[/tex] = [tex]\frac{1}{9}[/tex],

If you bump into somebody with the same force, how come only one of the people gets knocked down? Please give a detailed response I will be marking brainliest.

Answers

Answer:

It actually depends.

If person A bumps person B, it is most likely that person B will fall due to the fact that it is unexpected. Person B hasn't prepared her/his body for the impact so person B will fall.

If person A and person B both run and bump each other, both of them will fall due to the impact.

A carpenter had a board that was 2 yard long. He used 18 inches on a project. How many feet long was the board when he was done?

2 1/2 feet

4 1/2 feet

3 3/4 feet

1 1/4 feet

Answers

Answer:

4 1/2 ft

Step-by-step explanation:

1 yard = 36 inches

2 yards = 2 × 1 yard = 2 × 36 inches = 72 inches

The board started with a length of 72 inches.

He used 18 inches.

72 in. - 18 in. = 54 in.

He has 54 in. left.

Now we convert 54 in. to ft.

1 ft = 12 in.

54 in. × (1 ft)/(12 in.) = 4.5 ft = 4 1/2 ft

Answer:

Well the reason only one of gets knocked down is because even though you hit each other with the same force the other person might be lighter than you so the weight of you or the person you bumped into effects who gets pushed down

A rectangle’s perimeter is 28 meters and its area is 46 square meters. How long is its
longest side, in meters?

Answers

Answer:

I'm not sure but I think that it is 10.5

Step-by-step explanation:

The longest side is 8.73 meters long

Given that area of rectangle is 48 square meters and perimeter is 28 meters, we need to find the longest side length

What is perimeter and area of a rectangle?

Perimeter = 2(L+B)

Area=L×B

2(L+B)=28

L+B=14....(1)

LB=46....(2)

L=46/B (From2)

Put the value of L in (1)

46/B+B=14

B^2-14B+8=0

By solving above equation we get B=8.73

substitute value of B in 1

L+8.73=14

L=5.27

Therefore longest side in meters is 8.73

PLSSS HELPPPP MEEEEEE I NEED HELP HOENSTLYY I DONT UNDETRSTAND THIS

Answers

Step-by-step explanation:

Hey so ok, Ill explain this the best I can.

So you see the 10/2 (10/2 is the fraction just you cant type it in that way)

So 10/2 is litterally 10÷2, which is 5 just imagine that the line inbetween is a division symbol, and it goes from top to bottom, so for example 5/2 would be 5÷2... NOT 2÷5

With this said, to simplify 10/2, just divide the numerator, (Top) by the denominator (bottom) so --> 10÷2 = 5,

so Wednesday would equal 5 (and 5 is the same as 5/1 because 5÷1=5)

Do the same for Thursday 18÷3 = 6

So Thursday would equal 6 (and 6 is the same as 6/1 because 6÷1=6)

and since 6 > 5, (aka 6/1 > 5/1) She ran a longer distance per mile on Thursday, therefore she ran faster on Thursday.
