Answer:

<X =48

<Y =96

<Z = 36

Step-by-step explanation:

The three angles of a triangle add to 180 degrees

3.2n + 6.4n +2.4n = 180

Combine like terms

12n = 180

Divide each side by 12

12n/12 =180/12

n =15

<X = 3.2 n = 3.2 *15 =48

<Y = 6.4 n = 3.2 * 15 =96

<Z = 2.4 n = 2.4 * 15 =36

Answer:

<X = 48°

<Y = 96°

<Z = 36°

Step-by-step explanation:

<X +<Y+<Z = 180

3.2n + 6.4n + 2.4n = 180

12n = 180

n = 15

<X = 3.2(15) = 48

<Y = 6.4(15) = 96

<Z = 2.4(15) = 36

Answer:

$- \frac{71}{4}$

Step-by-step explanation:

$- 7 \frac{1}{10} \div \frac{2}{5}$

$= - \frac{71}{10} \times \frac{5}{2}$

$= - \frac{71}{2} \times \frac{1}{2}$

$= - \frac{71}{4}$

This makes no sense, help pls

stiv31 [10]

Please mark me branliest!

**Answer**

16 if you want exact, 20 if you want a little over.

**Explanation**

So check this... it's $50 per student that attends the camp, right?

(Nod if you're with me.)

The dude buys 5 dozen donuts for 16 days. 50 x 16 = 800

5 dozen is the same as 50 donuts.

You multiply to get the total amount of donuts he buys in the total days (16).

Each 10 donuts costs 10 dollars.

If the dude buys 800 donuts it cost him $800.

And it costs 50 dollars for someone to go to camp.

So you divide 800/50 = 16 students

Now the problem says "In order to break even" I'm not sure what that means. But I'm assuming it doesn't want 16 then, because the price of 16 students would be the same (even) as the price of donuts that Mr. Brook buys. In that case it would be 20.

You are very welcome!!

The figures below are made out of circles, semicircles, quarter circles, and a square. Find the area and the perimeter of each f

WITCHER [35]

Answer:

Part 1) $A=36(\pi-2)\ cm^2$

Part 2) $P=6(\pi+2\sqrt{2})\ cm$

Step-by-step explanation:

The picture of the question in the attached figure

Part 1) Find the area

we know that

The area of the shape is equal to the area of a quarter of circle minus the area of an isosceles right triangle

$A=\frac{1}{4}\pi r^{2}-\frac{1}{2}(b)(h)$

we have that the base and the height of triangle is equal to the radius of the circle

$r=12\ cm\\b=12\ cm\\h=12\ cm$

substitute

$A=\frac{1}{4}\pi (12)^{2}-\frac{1}{2}(12)(12)\\A=(36\pi-72)\ cm^2$

simplify

Factor 36

$A=36(\pi-2)\ cm^2$

Part 2) Find the perimeter

The perimeter of the figure is equal to the circumference of a quarter of circle plus the hypotenuse of the right triangle

The circumference of a quarter of circle is equal to

$C=\frac{1}{4}(2\pi r)=\frac{1}{2}\pi r$

substitute the given values

$C=\frac{1}{2}\pi (12)\\C=6\pi\ cm$

Applying the Pythagorean Theorem

The hypotenuse of right triangle is equal to

$AC=\sqrt{12^2+12^2}\\AC=\sqrt{288}\ cm$

simplify

$AC=12\sqrt{2}\ cm$

Find the perimeter

$P=(6\pi+12\sqrt{2})\ cm$

simplify

Factor 6

$P=6(\pi+2\sqrt{2})\ cm$
