A picture frame is shaped like a rectangle whose perimeter is 140 cm. The length is 4 times as long as the width. Find the length and the width.​

Answers

Answer 1

Answer:

L= 56cm

W= 14cm

Step-by-step explanation:

Given data

Perimeter of the frame= 140cm

Let the width be

W=x cm

Length= 4x

We know that

P= 2L+2W

subsitute

140= 2(4x)+2(x)

140 = 8x+2x

140= 10x

Divide both sides by 10

x= 140/10

x= 14cm

The length is

L= 4(14)

L= 56cm

Find the slope of the line passing through the points and ( -6, -5 ) and (4, 4)

Answers

Answer:

Slope: 9/10

Step-by-step explanation:

We need to find the slope of the line that passes through the coordinates given.

To find the slope, we would use the slope formula: m = y2-y1/x2-x1

Plug in your coordinates and solve:

m = 4-(-5)/4-(-6)

m = 4+5/4+6

m = 9/10

Since we can't simplify further, the slope of the line would be 9/10.

Simplify by combining like terms: 3x - 5 + 12x - 10

What is the sum of the greatest and least numbers below:

Answers

Answer:

1/6

Step-by-step explanation:

Step 1: Make remaining mixed numbers improper fractions:

8 1/5 = ((8*5)+1)/5 = 41/5

-8 2/5 = -((8*5)+2)/5 = -42/5

Step 2: Order fractions from least to greatest:

-26/3 <- Least

-42/5

-54/7

41/5

53/6 <- Greatest

Step 3: Find the sum of the least and greatest fractions:

Given: -26/3+53/6

Make equivalent fractions: -52/6+53/6

Rearrange: 53/6-52/6

Evaluate: (53-52)/6 = 1/6

Therefore, the sum of the greatest and least numbers is 1/6

8.20= 8 1/5. -2 2/5= -8.4. -26/3= -8.6. -54/7=- 7.71. 53/6=8.8
53/6, 8 2/5 ,8 1/5, -54/7, -2 2/5, -26/3

John needs a computer for his summer class. The computer costs 385 but since he is still in school, he gets a 30% discount. What is the total amount he will spend on his computer?

Answers

Answer:

269.50, you could search it up

The total amount that he will spend on his computer will be $269.5.

What is the percentage?

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

For his summer course, John has to have a computer. Since he is still enrolled in school, he receives a 30% discount off the computer's $385 price.

The amount of discount is calculated as,

⇒ 0.30 x 385

⇒ 115.5

Then the amount spent on the computer is calculated as,

⇒ 385 - 115.5

⇒ 269.5

The total amount that he will spend on his computer will be $269.5.
