Which is greater: 25% of 15 or 15% of 25? Explain your reasoning using mathematical evidence or visual models.

Answer:

7 x 1 = 7

Step-by-step explanation:

This is correct because Associative property of Multiplication means that you can change the grouping of the numbers and it will not affect the answer.

Answer:

The first question is 699.

The second question is 82.875.

Step-by-step explanation:

To find the are of the floor, we would take the volume formula for the rectangular prism and do it reversed.

V = l*w*h

2,097 = l*w*3

Divied by 3

699 = l*w

Since the area of a floor is l*w, we have found the area of the floor already.

699 feet^2

8 1/2 is 8.5. 3 1/4 is 3.25 To find the volume of a rectangular prism, it is l*w*h

3*8.5*3.25 = 82.875

Answer:

Area of floor= 699 sq ft

Volume of prism = 82 7/8 cubic ft.

Step-by-step explanation:

QUESTION 1

Given:

Volume of rectangular storage room = 2097 ft³

hieght of the storage room= 3ft

To find:

The area of rectangular floor = ?

Solution:

[tex]Volume \: of \: room = Area \: of \: floor \times height \: of \: room \\ 2097 = Area \: of \: floor \times 3 \\ Area \: of \: floor = \frac{2097}{3} \frac{ {ft}^{3} }{ft} \\ Area \: of \: floor = \cancel\frac{2097}{3} \cancel\frac{ {ft}^{3} }{ft} = 699 \: {ft}^{2} \\ \fbox{Area \: of \: floor = \: 699 \: sq.ft. }[/tex]

QUESTION 2

Given:

Length of rectangular prism l = 3 ft

width of rectangular prism w= 3 1/4 ft

Height of rectangular prism h= 8 1/2 ft

To find:

Volume of rectangular prism =?

Solution:

[tex]Volume \: of \: rectangular \: prism= l \times w \times h \\ Volume \: of \: rectangular \: prism = 3 \times (3 \frac{1}{4} ) \times (8 \frac{1}{2} ) \\ Volume \: of \: rectangular \: prism = 3 \times ( \frac{4 \times 3 + 1}{4} ) \times \frac{8 \times 2 + 1}{2} \\ Volume \: of \: rectangular \: prism = 3 \times \frac{13}{4} \times \frac{17}{2} \\ Volume \: of \: rectangular \: prism = \frac{663}{8} \\Volume \: of \: rectangular \: prism = 82 \frac{7}{8} \: cubic \: ft[/tex]

Answer: $55.00

Step-by-step explanation:

5.75 x 5 = 28.75
2.00 x 5 = 10.00

3.25 x 5 = 16.25

28.75 + 10.00 + 16.25 = 50.00

Answer:

15900 because 212x75=15900

Step-by-step explanation:

The actual width, w, of the island is 22.5 inches if the width in the drawing is 2.5 inches.

The actual width can be determined by multiplying the width with the scale factor.

Given that:

[tex]\mathbf{\dfrac{1.5}{1}=\dfrac{x}{6}}[/tex]

[tex]\mathbf{\dfrac{1.5}{1} \times 6=x}[/tex]

x = 9

If the width of the drawing is 2.5 inches, the actual width of the island is:

= scale factor × width of the drawing

= 9 × 2.5 inches

= 22.5 inches.

Answer:

25x^2 - 20x + 4

Hey there!

(5x - 2)^2

= (5x - 2)(5x - 2)

The answer is a

2/3=4/6 qhen you use butterfly method you get 12 for each 2×6=12 and 4×3

same for 6/9and 8/12 you use butter fly method to get 72 for each 6×12=72 and 8×9=72

Answer:

first of all what you have to do is to use a method called distribute property when you see this type of questions and multiply for example 3 times 6f and getting an answer of 18f and then finally you just multiply 3 times 8 and the answer is 24 so basically the answer should be 18f+24 and hope this helps and can you also tell me the answer choices and if it was correct or not and thanks for helping you.

Step-by-step explanation:

Answer:

18f+24

Step-by-step explanation:

Use the Distributive Property of Multiplication...

3 x 6f = 18f (note; when multiplying a number by a veriable, just add the variable to the product).

3 x 8 = 24

answer: 18f+24

Answer:

Group 1: 2x, -4x, 25x

Group 2: -3y, y

Group 3: 10, -6, 100

Group 4: -6x^2, 5x^2

Step-by-step explanation:

In eac group they are the ones that can be combined together, you cannot combine numbers from diffrent groups because they are not like terms.

Answer:

Percent Change

[tex]\sf percent\:change=\dfrac{final\:value-initial\:value}{initial\:value} \times 100[/tex]

[tex]\sf \implies \textsf{percent change from 1845-1846}=\dfrac{148-118}{118} \times 100=25.4 \%[/tex]

[tex]\sf \implies \textsf{percent change from 1846-1847}=\dfrac{139-148}{148} \times 100=-6.1 \%[/tex]

[tex]\sf \implies \textsf{percent change from 1847-1848}=\dfrac{151-139}{139} \times 100=8.6 \%[/tex]

Step-by-step explanation:

factoring out [tex]\frac{1}{10}[/tex] from [tex]\frac{1}{10}x[/tex] leaves 1x which can be written as just x. factoring [tex]\frac{1}{10}[/tex] from [tex]\frac{9}{10}[/tex] gives you just 9.

so [tex]\frac{1}{10} (x-9)[/tex].
