The rectangle shown has a perimeter of 56 cm and the given area. Its length is 8 times more than three times its width. Write and solve a system of equations to find the dimensions of the rectangle.

Answers

Answer 1

Answer:

Dimensions of rectangle = 23 cm x 5 cm

Step-by-step explanation:

Equations we can form

Perimeter of 56 cm

⇒ 2L + 2W = 56

⇒ L + W = 28

Length is 8 more than 3 times its width

⇒ L = 3W + 8

Substitute in previous equation

⇒ 3W + 8 + W = 28

⇒ 4W = 20

⇒ W = 5 cm

⇒ L = 28 - 5 = 23 cm

Hey there!

First, let's convert 4 into a fraction: 4/1

Now, multiply fractions:

1/4*4/1=1

is 1 greater than 4? of course not.

let's try Option B:

5/6*4/1

5 times 4 and 6 times 1

20/6

reduce the fraction

10/3

or

3+1/3 (less than 4)

Is it Option C? Let's try/

3/2*4/1

3 times 4 and 2 times 1

12/2

6

and 6 is greater than 4. Bingo!

How about Option D?

9/10*4/1

9 times 4 and 10 times 1

36/10

18/5

Hence, the answer is

Select all the situations where knowing the volume of an object would be more useful than knowing its surface area.

A. Measuring the amount of gasoline left in the tank of a tractor.

B. Packing a box with watermelons for shipping.

C. Filling an aquarium with buckets of water.

D. Charging a company for ad space on your race car.

E. Determining the amount of paint needed to paint a barn.

F. Determining the monetary value of a piece of gold jewelry.

G. Deciding how much wrapping paper a gift will need.

Answers

Answer:

The answers are A, B, C, and probably F

Step-by-step explanation:

Volume is how much space an object takes up, while surface area is how much space is on the surface of the object. In option A, we are measuring how much gas can fit in a tank, so volume is used. B and C are also dealing with filling a container. Options D, E, and G are measuring the surface area because they are asking how much of something is needed to cover the surface of a car, barn, and gift. In option F, assuming that the jewelry is pure gold, not just a metal with a gold coating, volume is used.

Hope this helps!

Mr. Sanko downloaded 34 more songs than Mrs. Sanko downloaded. Together they downloaded 220 songs. How many songs did each download?
Let X=Mr. Sanko and Y=Mrs. Sanko

a. Mr. Sanko downloaded 127 songs.
Mrs. Sanko downloaded 93 songs.
b. Mr. Sanko downloaded 93 songs.
Mrs. Sanko downloaded 127 songs.
c. They downloaded the same amount of songs.

Part b: Type the two equations for this situation:

Answers

Short Answer part 1: A
Short Answer part 2: 34+y=x and x+y=220

Explanation: Mr. S (x) downloaded 34 more songs than Mrs. S (y), and so the amount of songs that mr downloaded is equal to the amount of songs Mrs downloaded plus 34. ((34+y=x))

If you add together the amount of songs that mr (x) and Mrs (y) downloaded you will get ((x+y=220)).

Because mr’s (x) songs are equal to ((34+y)), you can substitute the value of x in for x in the equation ((x+y=220)), thus creating the equation ((34+y+y=220)).

Simplify ((34+y+y=220)) by first combining like terms, and then solving for y. When you solve for y, you will find that ((y=93)).

If you plug that value into ((34+y=x)), you will find the equation ((34+93=x)).

Solve for x.

((x=127))

Mr. Sanko (x) downloaded 127 songs, giving you the answer a.

Answers

Step-by-step explanation:

For rounded values, the minimum value they could have been rounded from is the given value less half its least-significant digit.

That means the minimums are ...

  a: 340 ⇒ 340 -5 = 335

  b: 49.8 ⇒ 49.8 -0.05 = 49.75

Then the minimum product would be ...

vertically stretched by a factor of 2, then translated
4 units left and 1 unit down

Answers

A vertical stretch of scale factor 2, followed by a translation of 4 units left and 1 unit down is written as:

g(x) = 2*f(x + 4) - 1

How to write the given transformation?

For a general function f(x), a vertical stretch of scale factor K is written as:

g(x) = K*f(x).

Horizontal translation:

For a general function f(x), a horizontal translation of N units is written as:

g(x) = f(x + N).

If N is positive, the shift is to the left.If N is negative, the shift is to the right.

Vertical translation:

For a general function f(x), a vertical translation of N units is written as:

g(x) = f(x) + N.

If N is positive, the shift is upwards.If N is negative, the shift is downwards.

So, if we start with a function f(x) and we stretch it vertically with a scale factor of 2, we get:

g(x) = 2*f(x)

Then we translate it 4 units left:

g(x) = 2*f(x + 4)

Then we translate 1 unit down:

g(x) = 2*f(x + 4) - 1

This is the equation for the transformation.
