Celine is 28, celines age is 4 more than 1/3 of drakes age. How old is drake?

Answers

Answer:

Step-by-step explanation:

C = 28

C = 4 + 1/3 D

This means that

28 = 4 + 1/3 D

Subtract 4 from both sides.

24 = 1/3 D

Then to get rid of the fraction, multiply both sides by 3

72 = D

Therefore Drake is 72.

Answer:

72

To determine the number of deer in a forest, a forest ranger tags 280 and releases them back into the forest. Later, 405 deer are caught, out of which 45 of them are tagged. About how many deer are in the forest?

Answers

Answer:

640

Step-by-step explanation:

405-45= 360

360+280=640

Answer:

2520 deer

Step-by-step explanation:

Given

Tagged deer = 280Caught deer = 405Tagged among caught = 45

The ratio of the tagged deer vs total

45 ⇔ 405280 ⇔ x

Solving by cross-multiplication

45x = 405*280x = 405*280/45x = 2520

So there are about 2520 deer in the forest

Name an irrational number ( in radical form ) located between 7 and 8. Explain your answer.

Answers

Answer:

[tex]\sqrt{59}[/tex]

Step-by-step explanation:

7^2 is 49 and 8^2 is 64, which means the square root of any number between 49 and 64 (exclusive) will be in between 7 and 8, and it's also going to be irrational, because it's not a perfect square.

One number between 49 and 64 is 59, so [tex]\sqrt{59}[/tex] is an irrational number between 7 and 8

Marissa has a goal of shooting exactly 400 three–pointers during her basketball practice every week. She has already shot 105 of them over the first two days of practice. Write an equation to represent how many three–pointers (t) Marissa has to average over the next 5 days to reach her goal.

Answers

Answer: 5t = 400-105

Step-by-step explanation:

Let t= Number of three–pointers Marissa has to average over the next 5 days to reach her goal. .

Goal = 400 three–pointers every week.

Marissa has already shot  = 105 three–pointers

Remaining shots to achieve target (5t) = Goal - (Marissa has already shot)

i.e. 5t = 400-105  (required equation)

⇒ 5t = 295

⇒ t = 59

hence, she need to make 59 shots per day for next 5 days.

The other is the Base

and the last one is perpendicular

Step-by-step explanation:directly

opposite the right angle is The HYPOTENUESE

Answer:  Hypotenuse

For any triangle, the longest side is always opposite the largest angle. The largest angle of a right triangle is always the 90 degree angle. If you had any larger angle, then the triangle wouldn't be a right triangle and instead it would be obtuse.

In a right triangle, the longest side is given the special name hypotenuse. The other sides of a right triangle are called the legs.

find the compound interest
on Rs 4000 for 30 months at 10% per annum​

Answers

Answer:

Rs. 1076.23

Step-by-step explanation:

The compound interest is given by the formula;

A=P(1+r/n  )^nt

where

A= amount at the elapse of the period

P= principal amount = Rs=4000

r=rate of interest=10% =0.1

n=number of times the interest is applied per time period= 1

t=number of time periods elapsed = 30 months = 30/12 = 2.5 years

Applying the formula;

A=P(1+r/n  )^nt

A=4000( 1+ 0.1/1)^1*2.5

A=4000(1.1)^2.5

A=4000 * 1.2691

A=Rs. 5076.24

Compound interest  will be : 5076.24-4000 = Rs. 1076.23

John has a soup recipe that calls for two 14.5-ounce cans of chicken broth. The recipe serves 4 people. He wants to increase the recipe to serve it to a party of 28 people. If John buys chicken broth in 1-quart containers, how many containers does he need?

Answers

Answer:

  6 11/32

Step-by-step explanation:

The two cans of broth used in the recipe total 2·14.5 oz = 29 oz. The number of people John wants to serve is 28/4 = 7 times the number served by one recipe. So, the amount of broth needed is ...

  (29 oz)·7 = 203 oz

Each quart container of broth holds 32 oz, so John will need ...

  (203 oz)/(32 oz/container) = 6 11/32 containers

John needs 6 11/32 containers of broth.

_____

If John must buy the broth, he must buy 7 containers. he will have 21/32 of a container left over after making his soup.
