Xander needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items.
Slav-nsk [51]

Answer:

x ≥ 56

Step-by-step explanation:

The whole problem will have to equal at least 120. If Xander has already collected 64, then he has a certain number of cans, x, remaining to collect. Since the problem is saying he needs "at least 120" then x and 64 must have a sum of at least 120. Thus you set up the problem like:

x + 64 ≥ 120

You can solve this simply by subtracting 64 from both sides.

x + (64-64) ≥ (120-64)

That would leave us with the answer:

x ≥ 54

Hope this helps!

help me find the volume and area of this figure step by step pleasefyi the answer key my teacher gave me says that the surface a
alisha [4.7K]

The volume of the shape

We have a cylinder that is cut into two. Its external radius is 5ft, while its internal radius is 4ft.

External radius = internal radius + thickness

\begin{gathered} \text{External radius = 4ft + 1ft } \\ =\text{  5ft} \end{gathered}

Internal radius = 4ft (given)

Recall that the volume(V) of a full cylinder is:

V\text{ = }\pi r^2h

Since the cylinder is cut into two, the volume(V) is:

V\text{ = }\frac{\pi r^2h}{2}

height (h) = 12ft (given)

The volume of the shape:

\begin{gathered} =\text{ Volume of cylinder with a radius of 5ft - Volume of cylinder with a radius of 4ft} \\ =\text{ }\frac{\pi\text{ }\times5^2\text{ }\times\text{ 12}}{2}\text{ - }\frac{\pi\text{ }\times4^2\text{ }\times\text{ 12}}{2} \\ =\text{ 471.239 - }301.593 \\ =169.65ft^3 \end{gathered}

What is the degree measure of angle bac? Round to the nearest whole degree
podryga [215]

The answer would be 70 degrees.

In order to find this answer, we must first look at the cos value of an angle. The unknown angle here gives us an adjacent side of 3.4 and a hypotenuse of 10. Thus, we can use the following with cos.

Cos(A) = 3.4/10 or Cos(A) = .34

As a result, we can then use the arccos function to find the answer.

acrcos(.34) = A

70.12 = A

Then when we round, we'd get 70.
