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

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.

Answer:

They bought 2 pounds of ground beef and 16 pounds of ground chicken.

Step-by-step explanation:

Let b be the beef, and c be the chicken:

b + c = 18, the pounds of beef and the pounds of chicken added equal 18 pounds

4b + 2c = 40, the beef costs 4 dollars per pound and the chicken costs 2 dollars per pound. They add up to 40 dollars total.

Use the equation b + c = 18 and subtract c from both sides to get b = 18 - c. We replace this equation with b in 4b + 2c = 40 to get 4(18 - c) + 2c = 40 because b is 18 - c.

Now we solve for c:

4(18 - c) + 2c = 40

Simplify:

72 - 4c + 2c = 40

Combine Like Terms:

72 - 2c = 40

subtract 72 from both sides:

-2c = -32

Divide Both Sides by 2:

-c = -16

Make the Equation Positive:

c = 16

Okay cool, now we know that they bought 16 pounds of chicken, to find out how much beef the bought, replace c by 16 in b + c = 18 to get b + 16 = 18

b + 16 = 18

Subtract 16 from both sides:

b = 2, they bought 2 pounds of beef

To check, replace c with 16 and b with 2 in 4b + 2c = 40 to get

4(2) + 2(16) = 40

Multiply:

8 + 32 = 40

40 = 40

The equation is true

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

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.
