The length of a rectangle is twice its width.
If the perimeter of the rectangle is 54 yd, find its length and width.

Answers

Answer 1

Answer:

Length 18 yds, Width 9 yds

Step-by-step explanation:

2x + 2x + x + x = 54

Combine like terms

6x = 54

Divide both sides by 6

x = 9

Plug 9 into equation above

2(9) + 2(9) + 9 + 9 =

18 + 18 + 18 = 54

What is Percentage?

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

8 2/3% into decimal.

So, 8 2/3%

= 26/3 %

= 26 /3 x 100

= 8.6666667 x 100

=866.6777

Find an equation of a line that has a slope 7 and passes through the point 3,11

Answers

You’re given that m=7 (slope is 7), so setup the slope-intercept form with that info: y = 7x + b.

Now you need to find b. Plug in (3,11) for x and y, x=3 and y=11.

11 = 7*3 + b

Notice the only variable left is b, so you’ll find b this way.

11 = 21 + b and then subtract 21 from both sides:

11 - 21 = b

-10 = b

Plug that back into the equation and you have y = 7x -10

What shape is always created in graphing the addition of two vectors?

Answers

Answer: Parallelogram

You could use the parallelogram rule to add the vectors, or you could use the tip-to-tail method (your textbook might call it the "head to tail method" but it's the same idea).

An example of the parallelogram method is shown below with adding the vector u = (-4,4) in red to the vector v = (8,2) in blue to get the vector w = (4,6) in green. The green resultant vector is one of the diagonals of the parallelogram

Side note: The other diagonal is either u-v or v-u depending on your reference point.

Answers

Answer:

18.5°, 55.5°, 106°

Step-by-step explanation:

Given:

B = 3AC = 6A - 5

Since the sum of three interior angles is 180°, solve for A:

A + B + C = 180A + 3A + 6A - 5 = 18010A = 185A = 18.5°

Find B and C:

B = 3*18.5 = 55.5°C = 6*18.5 - 5 = 106°

A motorboat travels 448 kilometers in 8 hours going upstream and 440 kilometers in 5 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?

Answers

9514 1404 393

Answer:

boat: 72 km/hcurrent: 16 km/h

Step-by-step explanation:

The speed difference between boat and current is the upstream rate:

  (448 km)/(8 h) = 56 km/h

The sum of speeds of boat and current is the downstream rate:

  (440 km)/(5 h) = 88 km/h

The rate of the boat is half the sum of these:

  (56 +88)/2 = 72 . . . km/h

The rate of the current is half their difference:

  (88 -56)/2 = 16 . . . km/h

The rate of the boat is 72 km/h; the rate of the current is 16 km/h.

Inverse for f(x)=1/2x+3

Answers

Answer: [tex]f^{-1}(x)=2x-6[/tex]

Step-by-step explanation:

To find the inverse, we want to switch the y with x and x with y. Once we do that, we solve for y.

[tex]y=\frac{1}{2}x+3[/tex]        [switch x and y]

[tex]x=\frac{1}{2}y+3[/tex]        [subtract both sides by 3]

[tex]x-3=\frac{1}{2} y[/tex]        [multiply both sides by 2]

[tex]y=2x-6[/tex]

Now, we know that  [tex]f^{-1}(x)=2x-6[/tex].

Answers

Answer: The length of LK is 40.

Step-by-step explanation:

LK = 6x+10

KM = 2x+8

LM = 58

so

LM = LK + KM

or, 58 = 6x+10+2x+8

or, 58 = 8x + 18

or, 58-18 = 8x

or, 8x = 40

so, x = 5

now

LK = 6x + 10

     = 6*5+10

     = 30 +10

     = 40
