A picture frame is 9 inches long and 6 inches wide. It can display a picture 6 inches long and 4 inches wide. What is the area of the picture frame?

Answers

Answer 1

Answer:

Answer:

30 inches squared

Step-by-step explanation:

First, find the area of the entire frame using length times height. 9*6 is 54 inches squared. Then, find the area of the middle space the same way. 6*4 is 24 inches squared. Lastly, subtract the middle from the entire frame's area. 54-24 is 30 inches squared.

Answer 2

Answer:

Answer:

30 in^2

Step-by-step explanation:

Frame

Length = 9

Width = 6

9 * 6 = 54in^2 (Multiply to get 54)

Picture

Length = 6

Width = 4

6*4 = 24in^2 ( Multiply to get 24 )

54 - 24 = 30in^2 ( Minus 24 from 54 to get 30)

Formula l*w

It's length times width NOT length times hight like the other person said

Twenty four(24) minus 1/3

Answers

23 and 2/3
you have 24 and you are taking away 1/3 of a whole
1/3 is equal to .333333333 repeating, as a decimal
therefore 1/3 is less than 1
you are taking away 1/3 of 1 away from 24
1 is equal to 3/3
take away 1/3 and you are left with 2/3
3/3-1/3=2/3
2/3 + 23 (the number that you did not touch)
and you are left with 23 2/3

What is the simplified form of the following expression?

Answers

Part a) $((4)/(7) )^(3)$

$((4)/(7) )^(3) =(4^(3))/(7^(3))= (64)/(343)$

therefore

the answer part a) is equal to

$(64)/(343)$

Part b) $(6xyz)/(2xz)$

$(6xyz)/(2xz)= ((2xz)(3y))/(2xz) = 3y$

therefore

the answer Part b) is equal to

$3y$

(4/7)^3=.1865

6xyz/2xz simplifies to 3y

John needs to make a scale drawing of his school building for art class. If the building is 256.25 meters long, and John scales it down using a ratio of 25 meters to 1 inch, how long will the building be in the sketch?My question is what do I start with first. Divide, multiply. and what numbers. My math is on line and I have not worked math problems in 30 years

Answers

Each 25 meter will be represented by a segment of 1 inch length. So for example a length of 250 meters, is drawn as 10 in on paper.

So first we need to know how many 25 meters are there in 256.25 meters, so we need to divide 256.25 meters by 25 meters which is 10.25.

This means we will draw 10.25 in.

at Mary's party 4/8 of the guest had chocolate ice cream and 3/8 of the guest had strawberry ice cream . what fraction of the ice cream was either chocolate or strawberry

Answers

7/8 because you add 4/8 and 3/8 together which is equal to 7/8.

7/8 I believe, as 4/8 had chocolate ice cream and 3/8 had strawberry and we don't know what the remaining 1/8 had, so just add who had strawberry and who had chocolate together and that will give you the probability.

Kira needs 3,000 milligrams of zinc for a science experiment. Which expression can be used to determine how many grams of zinc she needs? A. 1000 ÷ 3000
B. 1000 × 3000
C. 3000 ÷ 1000
D. 3000 × 100

Answers

We know $1000\;mg=1\;g$ . Therefore, 3000 mg of Zinc is equivalent to

$(3000\;mg)/(1000) =3000/1000=3\;g$ .

Thus the correct answer is (C).

C is the correct answer.
