Answers

Answer:

65 mph

Step-by-step explanation:

To find the unit rate (miles per hour), we can use the equation

[tex]r=\frac{d}{t}[/tex]

Where

r=rate (miles per hour)

d=distance (in miles)

t=time (in hours)

Using the given information, we can plug in

[tex]d=97\frac{1}{2}[/tex]

[tex]t=\frac{3}{2}[/tex]

So, our equation is

[tex]r=\frac{97.5}{1.5}[/tex]

When we divide 97.5 and 1.5, we get

[tex]65[/tex]

So,

[tex]r=65[/tex]

In conclusion, the rate (miles per hour) is 65 mph.

amogus =X^6 thats why u should vote kanye ty.

Answer:

A. both coordinates are positive.

Step-by-step explanation:

I'm attaching a picture. The lower right quadrant/quarter is where x is positive and y is negative. When you "reflect over the y axis" it's mirroring the position by flipping it above the y axis.

In my picture, I used the example of a filled in dot in the lower right quadrant at +2 x, and -2 y. Right above that, in the upper right quadrant, there's an unfilled circle at +2 x, and +2 y. The second point is the first after being "reflected over the y axis." X stays the same, but the y goes from negative to positive.

I hope this helps. Please ask me if it's still confusing.

Mr. Garcia worked 160 hours based off of what is given in the explanation above the table.

Mrs. Garcia works 24 hours a week and there are four weeks in a month. 24 x 4 = 96 hours.

To find the total hours they worked, you add both amounts together. 160 + 96 = 256 hours.

So then, you take their total expenses which is $4,295 and divide it by how many hours they work together to get the average of how much they should get paid to meet their budget standard. $4,295/256 = $16.78

5 2,430
Complete each of the 2 activities for this Task.
Activity 1 of 2
Write an equation where y represents the number of rabbits in x years.






Activity 2 of 2
A second population of 10 rabbits is placed in a second enclosed wildlife ranch and doubles each year.



Select all statements that are TRUE when comparing the equation of the second group of rabbits to the first group.

A.
The base of the exponent will change from 3 to 2.

B.
The function will become quadratic.

C.
The y-intercept will change.

D.
The second population will increase less rapidly.

Answers

Answer:

C

Step-by-step explanation:

First, we have to find the equation that will give the rabbit population as a function of time and the initial population.

The equation we need turns out to be Population = a0 x 3y  where a0 is the initial population and y is the number of years,

To find the rabbit population when a0 = 30 and y =3, use the equation to get Population = 30 x 33 = 810.  

You can now find the difference in the number of rabbits at year 3 for the different starting populations.

Cole is building a model rocket in science class. He selects the rocket parts from a set of solid cylinders and cones made from metal. Cole wants to build a rocket with the dimensions shown. For safety purposes, the maximum lift-off weight of each rocket is 10 pounds. Will Cole’s rocket meet the requirement for launch?

Part A
What will be the total length of the assembled rocket? Explain how you found your answer.
Part B
What is the approximate volume of the rocket. Use 3.14 for π. Explain.
Part C
If Cole’s rocket parts are made of aluminum weighing 0.006 pound per cubic centimeter, will Cole be able to launch his rocket? Explain.

Answers

A.

30 since 25 + 5 = 30

The maximum lift-off weight of each rocket is 10 pounds thus, Cole’s rocket doesn't meet the requirement for launch.

What is the volume of a cylinder?

The volume of the cylinder is the product of the height, pie, and square of the radius.

The volume of the cylinder = [tex]\pi r^{2} h[/tex]

Part A

The total length of the assembled rocket will be the length of the cone and the cylinder.

Height of the cone

[tex]\sqrt{l^{2} -r^{2} } \\\\\sqrt{5^{2} -4^{2} } \\[/tex] = 3 cm

The total length of the assembled rocket  = 25 + 3 = 28cm

Part B

The volume of the rocket is the combined volume of the cone and cylinder.

=  [tex]\pi r^{2} h[/tex] + 1/3[tex]\pi r^{2} h[/tex]

= 4/3 [tex]\pi r^{2} h[/tex]

=  4/3 × 3.14 × 16 × 28

= 1875.62 cubic cm

To convert cm into pound

1875.62 cubic cm = 4.135 pound

Part C

If Cole’s rocket parts are made of aluminum weighing 0.006 pounds per cubic centimeter.

Then 1875.62 cubic cm × 0.006

= 11.253

For safety purposes, the maximum lift-off weight of each rocket is 10 pounds. but Cole’s rocket doesn't meet the requirement for launch.

Answer:

x = 20

Step-by-step explanation:

Use Pythagorean Theorem to solve for x:

a^2 + b^2 = c^2

Plug in given values if a = 12, b = 16, and c = x (x is hypotenuse)

12^2 + 16^2 = x^2

(12*12) + (16*16) = x^2

144 + 256 = x^2

400 = x^2

Take square root of both sides to solve for x

sqrt(400) = sqrt(x^2)

20 = x or x = 20
