Please someone help me with this!

Mathematics
1 answer:
Olenka [21]3 years ago
3 0

Answer:

<u>Please read the answer below.</u>

Step-by-step explanation:

<u>Question 2. 25% of what number is 30?</u>

25% - Whole 30, 50% Whole 60, 75% Whole 90, 100% Whole 120

<u>Question 3. What operation did you use the find the whole?</u>

In the previous question, I found the whole, adding 30 to the previous value.

For example, I added 30 to 30 and calculate 60. To 60 then i added 30 to get 90 and added 30 to get 120 because in this question, all the 4 parts were exactly the same size (30).

<u>Question 4. What are you multiplying/dividing? Do you use the percent or something else?</u>

In the specific case of question 2, I noticed that the size of the parts were exactly the same, using it for calculating the whole. If 1 part out of 4 is 30, then 2 parts or 50% are 60, 3 parts or 75% are 90 and then 4 parts of 100% are the whole I'm being asked, in this case, 120.

What is the length and the width of a rectangle with perimeter of 48 inches if its length is 7 inches longer than its width.
sattari [20]

Answer:

Length and the width of the rectangle is 15.5 inches and 8.5 inches respectively.

Step-by-step explanation:

Given:

Length = 7 inches + Width

=> P = 48 inches

=> L = (7 + W) inches............. (1)

Perimeter 'P' is the sum of all sides of the rectangle 2 (L + W)

∴ 48 inches = 2 (L + W) .................(2)

Substitute for L in equation (2)

∴ 48 inches = 2 [(7 + W) + W]

48 = 2[7 + 2W]

48 = 14 +4W

48 - 14 = 4W

34 = 4W

W = 8.5 inches

Recall that: Length, L = (7 + W)

∴ L = (7 + 8.5)

L = 15.5 inches
