Elizabeth swims 50 feet in ten seconds. Jesse swims 110 feet in 20 seconds.
Reagan swims 160 feet in half a minute. Who swims fastest?

Answers

Answer 1

Answer: Jesse

Step-by-step explanation:

Elizabeth - 50f/10s

Jesse - 55f/10s

Reagan - 53.3333333/10s

Jesse is the fastest

Answer 2

Answer:

I think that Jessie swam the fastest

Step-by-step explanation:

Jessie swam the fastest bc Reagan only swims 160 feet in half a minute and 110 is less than 160 and 20 + 20 =40 so if Jessies swimming speed and time was multiplied by 2, she would still swim faster!

if zaeirr has 10 dogs and lamarr has 2 dogs how many more dogs does zaeirr have than lamarr?

Answers

Answer: 8

Step-by-step explanation:

For this problem, we would have to subtract the larger number of dogs by the smaller number of dogs. Zaierr has 10 dogs, and Lamarr has 2 dogs. We would have to subtract the number 10 by the number 2 to get our answer.

10 subtracted by 2 is equal to the number 8.

The answer to our question is 8.

10-2 = 8

So Zaeirr has 8 more dogs

A museum has an aquarium in the shape of a right rectangular prism that is 22.9m long, 7.5m wide and 4.6m high. What is the volume, rounded to the nearest cubic meter, of the aquarium?

Answers

Answer: The volume of the aquarium = 790 cubic meters

Step-by-step explanation:

Volume of rectangular prism = length x width x height

Given: An aquarium is in the shape of a right rectangular prism that is 22.9m long, 7.5m wide and 4.6m high.

Volume = [tex]22.9\times7.5\times4.6[/tex]

i.e. Volume = 790.05 cubic meters

i.e. Volume ≈ 790 cubic meters  (rounded to the nearest cubic meter)

Hence, the volume of the aquarium = 790 cubic meters (approx)

Answers

Answer:

x = 14,838

Step-by-step explanation:

equation is

x + 2,496 = 17,344

x = 17,344-2,496

x = 14,838

hope it helps you ☺️

The value of x when the sum of a number x and 2,496 is 17,344 should be considered as the 14,838.

Calculation of the value of x:

Since The sum of a number x and 2,496 is 17,344

will give brainliest to right answer please help!! 15 points -A sample of a radioactive isotope had an initial mass of 370 mg
in the year 2000 and decays exponentially over time. A
measurement in the year 2008 found that the sample's mass
had decayed to 110 mg. What would be the expected mass of the
sample in the year 2017, to the nearest whole number?

Answers

Answer:

78 mg

Step-by-step explanation:

370 mg - 110 mg = 260 mg (amount decayed in the 8 total years)

260 mg ÷ 8 years = 32.5 mg decayed per year

32.5 × 9 years (years between 2008 and 2017) = 292.5 mg

370 mg - 292.5 mg = 77.5 mg, rounded to 78 mg

the expected mass of the sample in the year 2017, to the nearest whole number is 0.

What is the formula for exponential growth and exponential decaying function?

The formula for exponential growth is y = y₀.e^(kt).

The formula for exponential decay is y = y₀.e^(-kt).

Given, Initial mass(y₀) = 370 mg.

After 8 years (t = 8) the mass decayed to y₈ = 110 mg.

∴ 110 = 370.e^(-8k).

e^(-8k) = 3.36.

lne^(-8k). = ln(3.36).

- 8k = 1.28.

k = - 1.28/8.

k = - 1.6.

Now expected mass of the sample in 2017 which in 9 years from 2008 will be,

y = 110.e^(-1.6×9).

y = 110.e^(-14.4).

y = 110/e^(14.4).

y = (110/1794074.78).

y = 6.13^(-5) mg.

y = 0.0000613 mg.

x is 30° and y is 20°.

Step-by-step explanation:

In an equilateral triangle all the angles form 60°.

1) 2x = 60

x = 60/2

x = 30°.

2) 3y = 60

y = 60/3

y = 20°.

x is 30° and y is 20°.

Answer:

y=20

x=30

Step-by-step explanation:

All the angles in an equilateral triangle is equal to 60 degrees. Knowing this, we can set up the following equations:

3y=60

2x=60

3y=60

Divide both sides by 3

3y/3=60/3

y=20

2x=60

Divide both sides by 2

2x/2=60/2

x=30
