ANTONII [103]

Answer:

$50\ games$

Step-by-step explanation:

Let

x-----> the total number of games the team played this year

Using proportion

$\frac{32\%}{16}=\frac{100\%}{x}\\ \\x=16*100/32\\ \\x=50\ games$

Will somebody please answer this question? I'm stuck and in a bit of a hurry. A surfboard shaper has to limit the cost of develo

ikadub [295]

Answer:

≥ 420 boards

Step-by-step explanation:

Write the required relation between cost per board and "x" (the number of boards that must be sold).

143 + 30240/x ≤ 215 . . . . . . . note that the first term is <em>not</em> 143x

Subtract 143

30240/x ≤ 72

Multiply by x/72. This is a positive number because x is a positive number.

30240/72 ≤ x

420 ≤ x

At least 420 surfboards must be sold to limit the final cost per board to $215.

Find the area of each shaded region. give your answer as a completely simplified exact value in terms of pi. (no approximates)

frez [133]

Answer:

52 $\pi$

Step-by-step explanation:

We see that the radius of the big circle is 8m, and we see that the it is also the diameter of the second smallest circle. We also see that this diameter is split into two equal parts, and since the entire length is 8, each part will be 4. So what we need to do is find the area of each circle.

First we can start by finding the area of the smallest circle. The radius of this circle will be 4/2, 2. So the area of this circle will be $\pi$ $r^{2}$ , and in this case 4 $\pi$ .

Then we need to find the area of the bigger shaded portion, which will be the area of the big circle, minus the area of the smaller white circle.

First, lets find the are of the big circle, which again, will be $\pi$ $r^{2}$ . This time, we plug in a radius of 8, and we get 64 $\pi$ .

Next we find the area of the smaller white circle, again $\pi$ $r^{2}$ . We use a radius of 4 this time, giving us an area of 16 $\pi$ .

Now we subtract the two values we found previously to find the area of the just the bigger shaded portion. That value will be 64 $\pi$ -16 $\pi$ , which is 48 $\pi$

We then take 48 $\pi$ , and we add the small shaded portion, which had an area of 4 $\pi$ , and we add them, giving us a total of 52 $\pi$ .

Hope this helped.
