Find the distance between each pair of points. Round to the tenths place.

Answers

Answer:

12.0

Step-by-step explanation:

Given the two points shown on the graph above, assuming 1 unit = 1 box, the coordinates of the two points are: (2, 7) and (-6, -2)

Use the distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_2)^2} [/tex], to find the distance between points (2, 7) and (-6, -2)

Let,

[tex] (2, 7) = (x_1, y_1) [/tex]

[tex] (-6, -2) = (x_2, y_2) [/tex]

[tex] d = \sqrt{(-6 - 2)^2 + (-2 - 7)^2} [/tex]

[tex] d = \sqrt{(-8)^2 + (-9)^2} [/tex]

[tex] d = \sqrt{64 + 81} = \sqrt{145} = 12.0 units [/tex] (nearest tenth)

Answer:

q = 5/6

Step-by-step explanation:

First, we distribute.

16q - 10 = 4q

Then, we combine like terms.

-10 = 4q - 16q

-10 = -12q

Finally, we divide -12 on both sides.

5/6 = q, or q = 5/6

A survey showed that 4 out of 5 students own a bicycle. Based on this result, how many of the 800 students in a school own a bicycle? Use any strategy to solve.

Answers

Answer:

640 students

Step-by-step explanation:

We are told in the question that 4 out of every 5 students owns a bicycle

This also means , out of every 5 students only 1 does not have bicycle

Then we have a ratio of 4 : 1

This means a fraction of 4/5 students own a bicycle in a school

Based on this result, how many of the 800 students in a school own a bicycle?

This calculated as:

4/5 × 800

= 640 students

Therefore, 640 students out of 800 students own a bicycle

Answers

Answer:

The low is -13 degrees Fahrenheit. The high is 109.4 or 109 2/5 degrees Fahrenheit.

Step-by-step explanation:

To get the low you plug -25 in for C(Celsius) and then you solve for F. First you can multiply both sides by nine. Second you need to distribute the 5, and this will give you 5F-160. Next add 160 to both sides, and now you should have, -65 = 5F. And finally you divide both sides by five to get a final answer of F = -13. To get the high follow these steps again, except this time plug in 43 for C.

0.7 (3s + 4)-1.1s = 7.9

Answers

Answer:

s = 5.1

Step-by-step explanation:

[tex]0.7 (3s + 4)-1.1s = 7.9\\[/tex]

Multiply both sides of the equation by 10

[tex]0.7\left(3s+4\right)\cdot \:10-1.1s\cdot \:10=7.9\cdot \:10\\\\= 7\left(3s+4\right)-11s=79\\[/tex]

Expand

[tex]\mathrm{Expand\:}7\left(3s+4\right)-11s:\\\quad 10s+28[/tex]

Subtract 28 from both sides

[tex]10s+28-28=79-28[/tex]

Simplify

[tex]10s=51[/tex]

Divide both sides of the equation by 10

[tex]\frac{10s}{10}=\frac{51}{10}[/tex]

Simplify

[tex]s=\frac{51}{10}\\\\Decimal = 5.1[/tex]

First multiply 0.7 by (3s+4) to get 2.1s + 2.8 and then add the 1.1s to the 2.1s and that should leave you with 1s+2.8 now you should have 1s + 2.8 = 7.9, you want to take 2.8 from both sides to bring it over to the 7.9 to make it look like 1s = 7.9 - 2.8 so now go ahead and have the 7.9 and the 2.8 subtract so you should end up with 1s = 5.1 so now you want to divide both sides by 1 and the 1s would cancel out into s and the 5.1 stays the same so now you have s = 5.1, you can always check this answer by seeing that it works so here is how you do that. Plug in your number, so you have
0.7 (3 * 5.1+4) - 1.1 * 5.1 = 7.9
here is your verification, 0.7 multiplied by all the numbers in the parentheses (3 * 5.1+4) would get you with 10.71 + 28 and you have - 1.1 * 5.1 = 7.9 so now just add the 10.71 to the 2.8 to get 13.51 and multiply the 1.1 by the 5.1 to get 5.61 and subtract the two to get 7.9 and that’s 7.9 = 7.9 so I hope this was helpful!! ^_^

Answers

Answer:

100cm^3

Step-by-step explanation:

The volume of any cube or cuboid is calculate by simply multiplying the length by the width by the height.

So if our length is 10cm, our width is 5cm and our height is 2cm, then our volume is 10x5x2=100cm^3 (cubic centimeters-unit for volume.)

Step-by-step explanation:

37.03/2.3 = 16.1

Answer:

[tex]\boxed{\bold{\huge{\boxed{16.1}}}}[/tex]

Step-by-step explanation:

Let the first number be x and the second number be y

So, the condition is:

[tex]x * y = 37.03[/tex]

Given that x = 2.3

[tex]2.3 * y = 37.03[/tex]

Dividing both sides by 2.3

[tex]y = \frac{37.03}{2.3}[/tex]

[tex]y = 16.1[/tex]

Kaya rented a limousine for prom. The company charges a cleaning fee of $100 and an hourly rate of $45. Her total cost for the night was $437.50. For how many hours did Kaya rent the limousine?

Answers

Answer:

Number of hours= 7.5

Step-by-step explanation:

Giving the following information:

The company charges a cleaning fee of $100 and an hourly rate of $45.

Her total cost for the night was $437.50

First, we need to structure the total cost formula:

Total cost= 100 + 45*x

x= number of hours

437.5= 100 + 45x

337.5/45= x

x= 7.5

Number of hours= 7.5

Answer:

Kaya rented the limo for about 7.5 hours
