Meteor Crater, located near Flagstaff, Arizona, is a circular
crater with a circumference of 2.32 miles. What is the
approximate diameter of the crater?

Answers

Answer:

The approximate diameter of the crater is 0.74 mile.

Step-by-step explanation:

Circumference of a circle(C)=2*π*r(radius of the circle)

2.32 miles=2π*r

or, r=2.32 miles/2π

So, r=0.369 mile

Then,

d=2r

d=2*0.369 mile

So, d= 0.74 mile

Explain why the formula A = 1/2 ( bh ) works for finding the area of a triangle

Answers

Answer: It works because a triangle is half of a square and when you divide by two it helps because It is half of a square, the base x height works well because since we do base times height for parallelograms and it works the same for a triangle since this it is a parallelogram this is why A=1/2( bh ) works for finding the area of a triangle. let me if this helped or not.

A box contains 512 grams of cereal. one serving is 56 grams. how many servings of cereal dose the box contain? GETS BRAINLIEST

Answers

Answer:

the answer is 9.14 so that means about nine servings of cereal

Step-by-step explanation:

you you divide 512 and 56 and you get a total of 9.14

A box contains 512 grams of cereal.

one serving of cereal = 56

So, The number of servings of cereal contained in the box can be calculated by dividing the total of grams over one serving of cereal

∴ The number of servings = 512/56 and all the calculations done correctly would be the right answer

So, The correct answer is 9 8/56. Hope this helps!

13.At the Finch School bake sale, donuts sell
for $2 each muffins sell for $3 each. A
combined total of 104 donuts and muffins
are sold, resulting in $243 in sales. Which
of the following statements must be true?
a. 69 more muffins were sold than donuts.
b. 34 more muffins were sold than donuts.
c. 34 more donuts were sold than muffins.
d. 69 more donuts were sold than muffins.

Answers

Answer:

Step-by-step explanation:

create a system of equations:

d + m = 104

2d + 3m = 243

now use substitution method based on 'd = 104 - m'

2(104 - m) + 3m = 243

208 - 2m + 3m = 243

208 + m = 243

m = 35

So, 35 muffins and 69 donuts were sold.

This is 34 more donuts than muffins.

Nya wants to buy a sweater that had an original price of $50. The sweater is now discounted 15% and the sales tax rate is 6%. How much will Nya pay for the sweater? Round to the nearest cent (hundredths place). *

Answers

Answer:

$45.05

Step-by-step explanation:

Sale price of sweater is (1.00 - 0.15)($50), or 0.85($50) = $42.50. Nya has to pay 6% sales tax on this $42.50. Thus, the final amount due is

(1.00 + 0.06)($2.50) = $45.05

Answer:

46.42

Step-by-step explanation:

First step is to find the discount

Discount = original price * discount rate

= 55 * 20%

= 55*.20

=11

Take the discount from the original price and that is the new price

new price = original price - discount

= 55-11

=44

Now we need to find the tax

tax = new price * tax rate

= 44 * 5.5%

= 44 * .055

=2.42

The final price is the new price plus the tax

final price = new price + tax

= 44+2.42

=46.42

Therefore, Nya will pay $46.42 for the sweater if she buys it.

D. 735.25 cubic inches.

Step-by-step explanation:

Well hello there! My name is Lunako, and I'm here to help you out.

What we need to do:

Firstly, do you remember the formula for finding the volume of the sphere? Yep, it's 4π(r³/3)! I'll substitute r for 5.6 -- which is 11.2 divided by 2, but you knew that already right? -- and π for 3.14 -- I'm doing that for relative ease.

4(3.14) * (5.6³/3) {Firstly we need to need find the cube of 5.6. That would be 175.616. Let me show the work for that: 5.6 * 5.6 = 25 + 3 + 3 + 0.36 = 31.36; 31.36 * 5.6 = 150 + 5 + 1.5 + 0.3 + 18 + 0.6 + 0.18 + 0.036 = 155 + 1.8 + 18.6 + 0.216 = 156.8 + 18.816 = 175.616}

4(3.14) * (175.616/3) {Now divide 175.616 by 3 to get 58.5387 (rounded to 54 places).}

4(3.14) * 58.5387 {Now onto the left sides. 3.14 quadrupled is 12.56.}

12.56 * 58.5387 {Now for the last step: Multiplying 12.56 by 58.5387. The work for that is shown in the picture. You should get 735.246072.}

735.246072 in³ {While this is the answer, we need to round it to two decimal places, like in the answer choices. 6 is greater then 5, so round up to 735.25.}

735.25 in³ {And with that this problem is solved.}

The Answer:

The volume of the sphere is 735.25 cubic inches, which is D.
