The length of a rectangle is 3 cm longer than its width.
If the perimeter of the rectangle is 42 cm, find its area.

Answers

Answer:

108 cm²

Step-by-step explanation:

Area of a rectangle, A = length, l × width, w

Perimeter of a rectangle = (2 × length) + (2 × width)

42 cm = 2l + 2w

but length = w + 3cm

42 cm = 2(w + 3cm) + 2w

42 cm = 2w + 6cm + 2w

42 cm = 6cm + 4w

4w = (42 - 6) cm

4w = 36 cm

》w = 9cm

》l = w + 3cm = 9cm + 3cm

l = 12 cm

Area = 12 × 9 = 108 cm²

The answer is
(Simplify your answer.)

Answers

a= 9/11 and b=7/10

now,

ab = (9/11)×(7/10)

=63/110.......

the value of ab is 63/110 when a = 9/11 and b = 7/10

What is Simplification?

Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.

Given, the values of a and b are 9/11 and 7/10 respectively

thus,

ab = 9/11 * 7/10

simplifying it

ab = 63/110

Therefore, the value of ab is 63/110 when a = 9/11 and b = 7/10

Answer:

  A

Step-by-step explanation:

It is generally useful to look at the answer choices. Here, we observe that all of them have y with a positive coefficient on the left side of the inequality. This makes it relatively easy to choose the set of inequalities that matches the graph.

The shading is below the solid line and above the two dashed lines. This means we are looking for a set of inequalities that looks like ...

  ay + ( ) ≤ ( ) . . . . . shading below a solid line

  y + ( ) > ( ) . . . . . . shading above a dashed line

  y + ( ) > ( )

The only set of inequalities with these relationships is choice A.

Jim washes 2/3 of his car with 1/2 a bottle of soap. What fraction of the soap will he use to clean his entire car?​

Answers

Answer:

if he uses 1/2 for 2/3, then you can divide 2/3 and 1.2 by 2 to get the remaining soap needed to complete the wash

so to clean the last 1/3 of the car, he`ll use 1/4 of the remaining soap

the entire car needs 3/4 of a bottle of soap

Step-by-step explanation:

Since the angles form 180 degrees, it will be what the equation is equal to.

Make the equation:

8r + 5 + 5r + 6 = 180

Combine like terms:

8r + 5 + 5r + 6 = 180

13r + 5 + 6 = 180

13r + 11 = 180

Solve:

13r + 11 = 180
