Assume you know that a hot-air balloon is currently inflated with a certain amount of air and that the amount is a percent of the total amount required to inflate the balloon. Explain how you would determine the total amount of air required to inflate the balloon.

Answers

Answer 1

Answer:

Percent air is calculated as:

Percent air = Current amount/Total amount *100

Solve for total amount of air:

Total amount  = Current amount / Percent air * 100

Substitute the values in hand to get the answer

If c=g-4f, find trinomial that represents C when F=2x^2-5 and G=5x^2+x-3

Answers

Answer:

c = -3x² + x + 17

Step-by-step explanation:

c = g - 4f

f = 2x² - 5

g = 5x² + x - 3

c = (5x² + x - 3) - 4(2x² - 5)

c = 5x² + x - 3 - 8x² + 20

c = -3x² + x + 17

Circle theorems please help

Answers

Answer:

n = 28°

Step-by-step explanation:

The angle at the centre is twice the angle on the circle subtended on the same arc.

Also angles subtended on the same arc are congruent , thus

m = n

Then

35 + m = [tex]\frac{1}{2}[/tex] (98 + n ) ← multiply both sides by 2 to clear the fraction

70 + 2m = 98 + n , but since m = n, then

70 + 2m = 98 + m ( subtract m from both sides )

70 + m = 98 ( subtract 70 from both sides )

m = 14 and n = 28

A large aquarium should contain 10,000 liters of water when it is filled correctly. Fish will get sick if the aquarium gets down to 4,000 liters or less. One day over the weekend, there is an accident, and the tank cracks in 4 places, causing water to empty out of the aquarium at a rate of 20.5 liters per hour. The aquarium workers did not catch the leaks until 2 days later. How much water was left in the tank when the aquarium workers finally caught the leak? Based on the level of water, were fish sick?

Answers

Answer:

9016 litres left

Step-by-step explanation:

The fish were not sick.

You would multiply 20.5 by 48 which is the amount of hours in 2 days then subtract that amount from 10000 to see how much is left

Sal places $500 in a retirement account that offers a return of 3.5% compounded annually . He will not deposit or withdraw any money from the account . Which function represents f(t) , the amount of money in the account after years a f(t) = 500 * (0.035) ^ t c. F(t) = 500 + 0.035t f(t) = 500 * (1.035) ^ t d. F(t) = 500 + 1.035t

Answers

Answer:

f(t) = 500 * (1.035) ^ t

Step-by-step explanation:

A = p(1 + r/n)^nt

Where

A = future value = ?

P = principal = $500

r = interest rate = 3.5% = 0.035

n = number of periods = 1

t = number of years = t

A = p(1 + r/n)^nt

= 500(1 + 0.035/1)^1*t

= 500(1 + 0.035) ^t

= 500( 1.035)^t

= 500 * (1.035)^t

f(t) = 500 * (1.035) ^ t

Bertha deposited $1000 into a retirement account when she was 18. How much will Bertha have in this account after 50 years at a yearly simple interest rate of 7.5%?

Answers

Answer:

$4750

Step-by-step explanation:

Simple interest is the interest calculated on the principal at a given rate for a time period.

The simple interest formula is given as,

SI = P x R x T / 100

P = principal

R = rate

T = time

Amount = SI + P

The amount Bertha will have in his account after 50 years is $4750.

What is simple interest?

Simple interest is the interest calculated on the principal at a given rate for a time period.

The simple interest formula is given as,

SI = P x R x T / 100

P = principal

R = rate

T = time

We have,

P = $1000

T = 50

R = 7.5%

A = SI + P

SI = (1000 x 7.5 x 50) / 100

SI = 1000 X 7.5 X 50 / 1000

SI = $3750

A = SI + P

A = 3750 + 1000

A = $4750

Thus,

The amount Bertha will have in his account after 50 years is $4750.

The y intercept is where the line crosses the y axis which in this example is at (0, 2). The y intercept is 2. The slope can be found by plugging in the x and y values of any 2 points on the line into the equation: y2 - y1 / x2- x1:

y2 - y1 / x2- x1

Grace rakes leaves everyday for one week. She fills the same number of bags with leaves on each of the 5 weekdays. She fills 11 bags over the weekend. At the end of the week, Grace has filled a total of 26 bags. She wants to know how many bags she filled each weekday.

Answers

Answer:

3 bags per weekday

Step-by-step explanation:

Total bags of leaves at the end of the week = 26 bags

Bags of leaves she fills over the weekend = 11 bags

Bags of leaves she fills during weekdays = x bags

Total bags of leaves at the end of the week = Bags of leaves she fills over the weekend + Bags of leaves she fills during weekdays

26 = 11 + x

Subtract 11 from both sides

26 - 11 = 11 - 11 + x

15 = x

x = 15 bags

If she fills the same number of bags with leaves on each of the 5 weekdays.

how many bags she filled each weekday.

Bags she filled each weekday = Total Bags of leaves she fills during weekdays / 5 weekdays

= 15 bags / 5 weekdays

= 3 bags per weekday

Answer:

3

Step-by-step explanation:

1. Bags filled on weekdays + bags filled on weekends = total bags filled

2. 5b + 11 = 26

3. Isolate variable (subtract 11 from both sides) = 5b=15

4. Divide both sides by 5 = 15/5 = 3

5. How many bags does Grace fill each weekday? = 3

He then randomly selected the pieces he needed, assembled on rifle, and fired it. popularized in America when Eli Whitney used them to assemble muskets in the first years of the 19th century, allowed comparatively unskilled workers to manufacture vast quantities of arms rapidly and at lower expense, and made repair and replacement of parts exponentially simpler.

On a certain hot​ summer's 439 day, people used the public swimming pool. The daily prices are $1.75 for children and $2.50 for adults. The receipts for admission totaled $1021.00 How many children and how many adults swam at the public pool that​ day?

Answers

Answer:102 children and 337 adults swam at the publice pool that da

Step-by-step explanation:

let the number of children be x

and

the number of adults be y

such that the total number of people who came to use the public swimming pool be expressed as

x + y = 439----- Equation 1

and price  for swimming be expressed as

1.75x + 2.50y =1021----- Equation 2

Step 2

x + y = 439----- Equation 1

1.75x + 2.50y =1021----- Equation 2

First make x the subject formulae and put in equation 2

x= 439-y

1.75 (430-y) + 2.50y = 1021

Solving gives

768.25-1.75y+2.50y=1021

2.50y-1.75y=1021-768.25

0.75y=252.75

y =252.75/0.75  

y=337

To find x, put the value of y = 337 in equation 1

x+y= 439

x= 439-337

x=102

Therefore 102 children and 337 adults swam at the public pool that day
