Julio is running in a 13.1-mile race. There are water stops every 2.75 miles along the route from the beginning of the race.
What is the distance between the last water stop and the end of the race? Enter your answer in the box.

Answers

Answer:

The distance between the last water shop and the end of the race is 2.1 miles

Step-by-step explanation:

Keep on adding 2.75 until you get the number 11 or you can just multiply 2.75 by 4 and get 11. Subtract 11 from 13.1 and you will get 2.1 miles.

There is a graph image below.

answer pleaseeeeeeeeeeeeeeeee

Answers

You can answer this by plugging in the x values given in the chart.

For example let’s look at the first column where x is given to equal -1
If we know that x=-1 then we can substitute that for x in the given equation y= 3x+2 so now it looks like
y=3(-1)+2

The 3 and the -1 are spectated only by parenthesis meaning they are multiplied. So now it look like this:
y=-3+2
Now just add these terms together
y=-1
Now you know what goes in the y box under -1.
You can repeat this for each x value.

Let’s do one more, the box that has 0 In it. Remember this means x=0 so 0 can be put anywhere in the equation you see x.
Y=3(0)+2
Anything times 0 is zero
So you just have: y=0+2
So y=2
This would go in the box under the 0.

On Monday, the temperature was 43°F. On Tuesday, the temperature increased 6°F. On Wednesday, the temperature decreased 13°F. Which integer represents the overall change in temperature from Monday to Wednesday?

Answers

Answer:c Thursday

Step-by-step explanation:

If on Monday, the temperature was 43°F. On Tuesday, the temperature increased by 6°F the overall change in temperature from Monday to Wednesday will be  24°F.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.

It is given that on Monday, the temperature was 43°F. On Tuesday, the temperature increased by 6°F. On Wednesday, the temperature decreased by 13°F.

The overall change in temperature from Monday to Wednesday is found as,

=  43°F  + 6°F  - 13°F

= 24 °F

Thus, if on Monday, the temperature was 43°F. On Tuesday, the temperature increased by 6°F the overall change in temperature from Monday to Wednesday will be  24°F.

The property tax on a $60,000 home is $1,500. At this rate what will the property tax be on a home worth $75,000?

Answers

Answer:

The answer is $1,875

Step-by-step explanation:

1. I just divided $60,000 by 2 and $1,500 by 2 and got $30,000:$750

2. I realized I needed to do more so I divided again and got $15,000:$375. Next I added it to the question $60,000 + $15,000 = $75,000

3. So then $1,500 + $375 = $1,875

4. $75,000:$1,875

If f(x)=2x^3+4x^2, find f(-3)

Answers

Answer:

f(-3) = -18

Step-by-step explanation:

f(x)=2x^3+4x^2, find f(-3); let's rewrite

f(x) = 2[tex]x^{3}[/tex] + 4[tex]x^{2}[/tex]; substitute -3 for x

f(-3) = 2[tex](-3)^{3}[/tex] + 4[tex](-3)^{2}[/tex]; do the exponents

f(-3) = 2(-27) + 4(9); multiply and add

f(-3) = -54 + 36 = -18

The value of the function  f(x) = 2x³ + 4x² at f(-3) is - 18.

What is a function?

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given, A function f(x) = 2x³ + 4x².

Now, The value of the function f(-3) can be obtained by replacing

x with - 3.

Therefore, f(-3) = 2(-3)³ + 4(-3)².

f(-3) = 2×-27 + 4×9.

f(-3) = - 54 + 36.

f(-3) = - 18.

Jerry purchases a used sofa for $275. He cleans and reupholsters the sofa to make it look brand new. After all the improvements, Jerry sells the sofa for 40% more than what he originally purchased it for. What was the profit Jerry made after selling the sofa?

Answers

Answer:

$110

Step-by-step explanation:

Step one:

we are told that  the cost of the sofa is $275

also, he sells it for 40% more of the cost price

let us find 40% of $275

=40/100*275

=0.4*275

=110

=$110

Step two:

This means that the selling price is 275+110

=$385

profit = selling price- cost price

profit=385-275

profit=$110

4. John is packing books into boxes. Each box can hold either 15 small books or 8
large books. He needs to pack at least 35 boxes and at least 350 books, Write a
system of linear inequalities to represent the situation

Answers

Answer:

Your system of inequalities is:

x + y ≥ 35

15x + 8y ≥ 350

Step-by-step explanation:

Let x = number of boxes of small books and let y = number of boxes of large books.

 Since John needs to pack at least 35 boxes:

 (number of boxes of small books) + (number of boxes of large books) (is at least) 35

x + y ≥ 35

Since John needs to pack at least 350 books:

 (number of small books packed) + (number of large books packed) (is at least) 350

(number of small books per box)(number of boxes of small books) + (number of large books per box)(number of boxes of small books) ≥ 350

15x + 8y ≥ 350

determine the vertex of y=4(x-25)2+ 91

Answers

Answer:

             (25, 91)

Step-by-step explanation:

y = a(x - h)² + k        ← vertex form of  the equation of the parabola with vertex (h, k)

So y = 4(x - 25)² + 91  means:

a = 4

x - 25 = x - h    ⇒  - 25 = - h  ⇒  h = 25

+ 91 = + k     ⇒    k = 91

Therefore vertex is:
