Answer:

This is an equilateral triangle, meaning that all sides and all angles are equal, as shown through the three equal side lengths, so all you have to do is find what makes all three angles the same number!

A triangle has 180 degrees, and this one has 3 equal angles because it has 3 equal sides, so 180/3 is 60 degrees!

So C. 60 degrees is your answer!!

Hope this helps!

Since all of the sides of the triangle are equal, we know we are dealing with an equilateral triangle. An equilateral triangle has equal sides and all of its angles are equal as well. We also know that a triangle's angles add up to 180°. Therefore, if we were to divide 180° evenly between the three equal angles, we would discover that each angle measures 60°. Your answer is C.

Answer:

The sample size must be approximately 1067 to get a margin of error of 0.03.

Step-by-step explanation:

We are given the following in the question:

Margin of error = 0.03

Significance level = 5%

Margin of error =

$z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

Since, no prior proportions are given, we take

$\hat{p} = 0.5$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

Putting values, we get,

$0.03 = 1.96\sqrt{\dfrac{0.5(1-0.5)}{n}}\\\\\sqrt{n} = \dfrac{1.96\times 0.5}{0.03}\\\\\\sqrt{n} = 32.67\\n = 1067.3289\approx 1067$

Thus, the sample size must be approximately 1067 to get a margin of error of 0.03.

Noah and Lin are making paper cones to hold popcorn to hand out at parent math night. They want the cones to hold 9 cubic inches

Answer:

So, The possible values of h and r are

1. r = 3 , h = 3

2. r = 1, h = 27

3. r = 2, h = 6.75

Step-by-step explanation:

P.S - The exact ques is -

As we know that Volume of cone , V = $\frac{1}{3}\pi r^{2}h$

As given,

V = $9\pi$

⇒ $\frac{1}{3}\pi r^{2}h = 9\pi \\ \frac{1}{3} r^{2}h = 9 \\r^{2}h = 27$

So,

The possible values of h and r are

1. r = 3 , h = 3

2. r = 1, h = 27

3. r = 2, h = 6.75

In Case I-

When r = 3, h = 3

(3)² ×3 = 9×3 = 27

Satisfied

Case II-

r = 1, h = 27

(1)²×27 = 1×27 = 27

Satisfied

Case III-

r = 2, h = 6.75

(2)²×6.75 = 4×6.75 = 27

Satisfied

What is -0.18 as a fraction in simplest form.

Radda [10]

The answer is, 9/50
0.18 = 0.18/1
0.18/1 x 100/100 = 18/100
18/100 divided by 2/2 = 9/50
In conclusion the answer is 9/50.
Hopefully that helped! :)

The temperature outside dropped 13 F in in 7 hours. The final temperature was -2 F. What was the starting temperature?

butalik [34]

the final temperature was -2 F, and that reflects a drop of 13 units, so

-2------0------------------------------------------------------+11.
