My name is Ann [436]

Answer:

Amount each friend pays for the gift = $20

Step-by-step explanation:

Market price of a gift = $70

The store manager takes $10 off the market price.

Marked down amount = $10

New cost price = Marked price - Marked down amount $=\$70-\$10=\$60$

The cost of the gift is divided among three friends.

This means that the cost of gift which is $60 is divided by three to get each one's contribution in the gift.

∴ Amount each friend pays for the gift $=\frac{60}{3}=\$20$

This sequence seems to apply -9, +13, +6 repeatedly.

Monet measures the diameter of an Oreo and finds that each cookie is 1.75 inches across. Using Monet's measurement, calculate th

Anon25 [30]

Answer:

5.495 inches.

Step-by-step explanation:

We have been given that Monet measures the diameter of an Oreo and finds that each cookie is 1.75 inches across. We are asked to find the circumference of an Oreo.

We know that circumference of circle is equal to $2\pi r$ , where r represents radius of circle.

We also know that diameter is 2 times radius.

$D=2r$

Upon substituting $2r=\text{ 1.75 in}$ , we will get:

$\text{The circumference of an Oreo}=\text{ 1.75 in}\times \pi$

Using 3.14 as an estimation for π, we will get:

$\text{The circumference of an Oreo}=\text{ 1.75 in}\times 3.14$

$\text{The circumference of an Oreo}=5.495\text{ in}$

Therefore, the circumference of an Oreo would be 5.495 inches.
