It's helpful because let's say you have $3.23 and you need to give someone $1.00 then you would need to subtract then what way you will know what you need to do and how many money u have left

Its a lot easier to do 1.200 - .200. Than to do 1.248- .239. How I see it, estimating always gives you something to fall back on or to help see if your exact answer is accurate

Carlos didn't earn enough for the last apartment he was looking at, so he is still searching. He found one that costs $625 per m

tresset_1 [31]

Answer:

$1875

Step-by-step explanation:

Given the information:

An apartment costs: $625 per month
They require that the cost of rent be no greater that a third of his monthly income
The must earn at least 3 times the cost of his rent

=> the smallest amount of money that Carlos needs to make per month to be approved to move in:

= 3 times of $625

= 3*$625

= $1875

because 625 is exactly 1/3 of $1875

Hope it will find you well.

Tamika ran 120 meters in 21.6 seconds. Enrique ran 120 meters in 22.4

Alexus [3.1K]

Tamika ran the fastest time at 21.6 seconds in 120 meters because the faster you run the less time you have on your timer.

Gekata [30.6K]

Answer:

m < b = 76

jay beats terry at table tennis 3 out of 5 games. what is the experimental probability that terry will win their next game

lozanna [386]

Answer:

The experimental probability that terry will win their next game is $\frac{2}{5}$

Step-by-step explanation:

While theoretical probability is the ratio of the number of favourable outcomes to the total number of outcomes, the experimental probability is the ratio of number of times the event is occurring to the total number of trials of the experiment.

Out of 5 games jay wins 3

Now the experimental probability that terry will win their next game

= 1 - Probability of Jay winning the game----------------------(1)

Probability of Jay winning the game = $\frac{\text{number of occurrences of the event}}{\text{total number of trials made}}$

=> $\frac{3}{5}$ ----------------------------------------------------(2)

Substituting (2) in (1)

=> 1 - $\frac{3}{5}$

=> $\frac{5-3}{5}$

=> $\frac{2}{5}$
