Question 2

Mathematics

Answer:

Part A: OC. 16π square inches

Part B: OC. 36π square inches

Step-by-step explanation:

<u>Part A:</u>

Given

Diameter of circular picture = d = 8 inches

We need to find the radius first to find the area

So,

Rdius = r = d/2 = 8/2 = 4 inches

Area = \pi r^2\\= \pi *(4)^2\\= 16\pi\ square\ inches

Therefore, option C is the correct answer..

<u>Part B: </u>

As two inches frame is added around the picture, the diameter will become 8+4 =12 inches

The new radius will be:

r = 12/2 = 6

So,

Area\ with\ frame = \pi r^2\\=\pi *(6)^2\\=36\pi\ square inches

Therefore, option C is correct ..

You discover that you are over serving a dish because customers keep taking a third of it home. If the dish requires 4 ingredien
devlian [24]

Answer:

4 parts

Step-by-step explanation:

If the total number of parts is 12 and you want to reduce the dish to two-thirds its current size, the number of parts that will be reduced is (1 - 2/3) = 1/3

To reduce 1/3 of the 12 parts, you need to multiply 12 by 1/3 to know how many parts is that:

12 * 1/3 = 12/3 = 4

You need to subtract 4 parts. If you have 4 ingredients, you can remove 1 part of each, so each ingredient now will have 2 parts.

Which property would allow you to use mental computation to simplify the problem 27 + 15 + 3 + 5? additive identity additive inv
Fofino [41]

Answer:

Commutative Property

Step-by-step explanation:

Additive Identity: If you add a real number to zero or add zero to a real number, then you get the same real number back.

Additive Inverse: When you add the same number but reversed sign, you get 0.

Commutative Property: a + b = b + a

Addition distributive property: a(b+ c) = ab + ac.

In this case, we use the commutative property:

27 + 15 + 3 + 5 = 27 + 3 + 15 + 5.

We know that 27 + 3 = 30 and 15 + 5 = 20, so we get 50 quickly using mental math.
