Answer:

y = 6, RS = 35 and ST = 17

Step-by-step explanation:

Given that,

RS = 5y+5

ST = 2y+5

RT = 52

If we consider a number line,

RT = RS + ST

52 = 5y+5 + 2y+5

52 = 7y + 10

7y = 52-10

7y = 42

y = 6

RS = 5y+5

= 5(6)+5

= 35

ST = 2y+5

= 2(6) +5

= 17

Hence, this is the required solution.

Answer:

Expected value would be $ 0.896

Step-by-step explanation:

Given,

The price of the lottery ticket = $44800000,

Also, the probability of winning the grand prize = .000000020,

Thus, the expected value of the lottery ticket = value of the lottery ticket × probability of getting the lottery ticket

= 44800000 × .000000020

= $0.896

Note : value of lottery ticket = prize amount - cost of each ticket,

Here the cost price of a ticket is not given,

That's why we did not consider it.

Billy the friendly Robot uses 50 N of force to lift a box 2 meters in the air. How much work did Billy perform?
padilas [110]

Answer:

0.04

Step-by-step explanation:

Set it up like this: 50N=2.

you want to leave "N" by itself on one side of the equal sign so divide 50N by 50 and your are left with "N". You also have to divide 50 by 2 on the other side of the equal sign. now you have N=2÷50.

2÷50= 0.04!
