A water tank already contains 56 gallons of water in Baxter begins to fill it. water flows into the tank at a rate of 8 gallons per minute. write a linear equation to model this situation. Find the volume of the water in the sink 5 minutes after Baxter begins filling the tank.

Answers

Answer:

Equation: y = 8x + 56

After 5 minutes, the volume of the water was 96 gallons

Step-by-step explanation:

Use y = mx + b to create the linear equation, where m is the slope and b is the y intercept.

Since the water flows in at 8 gallons per minute, 8 will be the slope. The variable x will represent the number of minutes.

There are already 56 gallons of water in the tank, so b will be 56.

Plug in these values into the equation:

y = 8x + 56

So, the linear equation is y = 8x + 56

Using this, plug in 5 as x to find the volume of the water in the sink after 5 minutes:

y = 8x + 56

y = 8(5) + 56

y = 40 + 56

y = 96

So, after 5 minutes, the volume of the water was 96 gallons

It’s the third choice... the volume of the cylinder is greater than the cone by about 25

Volume of a cone = pi r square * height over 3
= pi * 4square *12/3=201.1

Volume of a cylinder = pi radius squared * height
= pi 3 square *8 = 226.2

226.2-201.1= 25.1

Which is an example of a quadratic function whose axis of symmetry is to the right of the y-axis?
A. y=-x2 - 2x + 1

Answers

Answer:

a.

Step-by-step explanation:

imagine a graph that you see, the x-axis has to be positive for it to be on the right side of the y-axis so the value of the y axis can be positive or negative and then you substitute for a positive number, in this case, into the x axis and then you would solve for every answer choice to see if it's right or not if it is accurate.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS - Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We need to Subtract 0.25 subtracted from 5

We know that 0.25 x 20 = 5

so, the subtraction is;

5 - 0.25 = 4.75

What is this question?

It’s 2/3. This is because 1/15 is 3/45 because 3 is the number of eclairs. So then (2x+6)+x=45-3. 3x+6=42. 3x=36. x=12. Humbug=2x+6. 2(12)+6=30. So the probability is 30/45, which can be reduced to 2/3. I hope this makes sense.

A particle is moving with the given data. Find the position of the particle. a(t) = t2 − 2t + 9, s(0) = 0, s(1) = 20

Answers

Answer:

Position of the particle is 20.

Step-by-step explanation:

Position function is integration of velocity function.

Velocity function is integration of acceleration function.

So, let's integrate the given a(t) to get v(t)

If we integrate v(t) then we get s(t)

It is given the values of s(0) =0 and s(1)=20

So, position of the particle is difference of 20, 0. That's 20-0 =20.

Answer:

x = 28.9

Step-by-step explanation:

tan = [tex]\frac{opposite}{adjacent}[/tex]

⇒ tan 48 = [tex]\frac{26}{x}[/tex]

(tan of 48 is 1.11)

⇒ 1.11 = [tex]\frac{26}{x}[/tex]

multiply 26 on both sides

⇒ 1.11 x 26 = [tex]\frac{26}{x}[/tex] x 26

⇒ 28.86 = x

round to the nearest tenth

⇒ 28.86 = 28.9

The total cost C dollars, that a shop charges to print T shirts C = 45 + 7n , is the number of shirts ordered. Coach Dell paid 206 fo order T the track team, How Tshirts did Coach Dell order?

Answers

Answer:

i think the answer is 23

Step-by-step explanation:

well the equation says c=45+7n so the total cost is 206 . i subtracted 45 from 206 leaving me with 161 then i divided that by 7 leaving me with 23

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The total cost of n T-shirt is C = 45 + 7n.

The number of T-shirt coach Dell ordered for the team is 23 T-shirts.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Total cost:

C = 45 + 7n

n = number of shirts.

Now,

Dell paid $206.

This means,

206 = 45 + 7n

Subtract 45 on both sides.

206 - 45 = 7n

161 = 7n

Divide both sides by 7.

n = 161/7

n = 23

The number of shirts is 23  if the cost of the paid is $206.

Thus,

The number of T-shirt coach Dell ordered for the team is 23 T-shirts.

A new motorcycle has a value of $8000 every year is value decreased by $500 which function can be used to find why the value of motorcycle in X years?

Answers

f(x) = 500x-8000

500 times the number of years (x), subtracted by the original price (8000)

The function for the value of the motorcycle after x years are;

y = 8000 - 500x

y = -500x + 8000

What is a function?

A function is a relationship between inputs where each input is related to exactly one output.

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have given that new motorcycle has a value of $8,000. Every year its value decreases by $500.

Now, we have y = amount of the motorcycle

x = number of years

The function for the value of the motorcycle after x years.

y = 8000 - 500x

y = -500x + 8000

Thus,

y = 8000 - 500x

y = -500x + 8000
