the radius is 2.5 all you had to do was divide 5 by 2 lol

Answer:

2.5

Step-by-step explanation:

The radius is any line from the middle of the circle to the end of the circle. The diameter is a chord which is a line going from any end of the circle to the other end but the diameter crosses though the point which is in the middle.

So, you split the diameter in half. 5/2 = 2.5

Un metro cúbico equivale a 1000 litros de capacidad y un decímetro cúbico a un litro ¿Cuántos litros cabrán en una piscina de 12,5 metros cúbicos?

Answers

Answer:

12,500 liters

Step-by-step explanation:

Given that

One cubic meter = 1000 liters

One cubic decimeter = 1 liter

We need to find out the number of liters fit in a 12.5 cubic meter

So

As it is mentioned that

One cubic meter = 1000 liters

So for 12.5 cubic meter

The number of liters would be

= 1000 × 12.5

= 12,500 liters

Kelly's team won 85% of the games they played in a season. The team lost 12 games. How many games did Kelly's win in the season?

Answers

Answer:

68 games

Step-by-step explanation:

Given data

out of 100%

they lost 15%

Let the total game played be x

so

15/100*x= 12

0.15x= 12

x= 12/0.15

x= 80 games

the total games played is 80

Hence the games won

=total games-games lost

=80-12

=68 games

Which of the following functions would give the population Plt) as a function
of t, in years, given that the initial population is 2,500 and that the population
is growing at an annual rate of 4%?
(1) P(t)=2500(0.96)
(3) P(t)=2,500(1.04)
(2) P(t)=(1.04) +2,500
(4) P(t)= 1.04t +2,500

Answers

Answer:

[tex]P(t)=2500(1.04)^t[/tex]

Step-by-step explanation:

None of your proposed answers has an exponent t.

Here's the logic behind the answer:

Year 0: pop. = 2500

Year 1:  pop. = 2500(1.04)  That is 104% of the previous year's pop.

Year 2: pop. = 2500(1.04)(1.04) = 2500(1.04)^2

Year 3: pop. = 2500(1.04)^2 x (1.04) = 2500(1.04)^3

See the pattern?  The exponent matches the year number.

Al cine paraíso fueron el sábado 1.350 espectadores y el domingo 1.120 cuánto se recaudo si cada entrada costaba 540?

Answers

Answer:

1,333,800

Step-by-step explanation:

Spectators on Saturday = 1,350

Spectators on Sunday = 1,120

Total spectators = 1,350 + 1,120 = 2,470

Price per ticket = 540

So, we can calculate the total amount collected by using following formula,

Total amount collected = Total spectators × Price per ticket

By putting value, we get

= 2,470 × 540

= 1,333,800

Answer: The answer is 280 ft.

Step-by-step explanation:

divide the green area into a triangle and a rectangle so it's easier to calculate. Then find the area of the rectangle by multiplying 14 times 16. That should get you 224. Then, find the area of the tringle by multiplying 14 times 18, times 1/2. That will get you 56. If you add 56 to 224, that gets you 280.

Marcus is rolling a number cube with sides labelled 1 to 6 .find the probability it will show 10​

Total sides of cube die = 6

Find:

Probability of getting number 10

Computation:

Total number of cube = 1, 2, 3, 4, 5, 6

Favorable outcome for 10 = 0

Probability of an event = Favorable outcome / Number of outcomes

Probability of getting number 10 = 0 / 6

Probability of getting number 10  = 0
