A plumber has a 2-meter length of pipe. He needs to cut it into sections that are 10 centimeters long. How many sections will he be able to cut? (I will give brainliest if you answer first)

Answers

Answer:

20 - 10 cm sections can be cut from a pipe of original length 2 m

Step-by-step explanation:

Convert 2 meters to cm:  

2 m       100 cm

------ * ---------------- = 200 cm

  1             1 m

Next, divide this 200 cm total length by (10 cm/section) to determine the number of sections:

200 cm

--------------------- = 20 sections

10 cm/section

20 - 10 cm sections can be cut from a pipe of original length 2 m

To pass her test, Tori needs to answer at least 65% of the questions correct. If there were 60
questions and she got 42 correct, did she pass? All work MUST be shown to justify your
answer.

Answers

1) change 65% to a decimal = .65

2) .65 • 60 = 37.2 questions need to be right

3) since she got 42 correct, that is greater than 37.2, so she passed.

OR

1) 42/60 = 0.7

2) 0.7 to a percent = 70%

3) since she got a 70% on the test, she passed.

Step-by-step explanation:

To obtain score of 80% on entire exam means the student have to answer

(80/100)×80 = 64 correct answers

Student have already answered 75% of the first 60 questions correctly meaning

(75/100)×60=45 correct answers from first 60 questions

Remaining correct answers s/he have to answer

64-45=19

So from remaining 20 questions s/he have to answer 19 correct questions that is

20 × (x/100) = 19

x = 19 ×(100/20)

x = 95%

Find the volume of a prism with a length of 4.5 inches, width of 5 inches, and a height that is one third of the length.

Answers

Answer:

33.75

Step-by-step explanation:

Formula: Width · Height · Length

Substitute with known values: 5 · height · 4.5

Find Length: Since the height is one third of the length, we need to divide the length by three → 4.5 ÷ 3 = 1.5

Know we know that the height is 1.5.

Substitute Known Height: 5 · 1.5 · 4.5

Simplify: 5 · 1.5 · 4.5  = 33.75

Chelsea buys a shirt and shoes at the store with the coupon. The price of the shirt before the discount is $22, and her total discount is $18.55. Write an equation to find a price of the shoes before the discount.
(THE COUPON IS IN THE PIC)

​

Answers

Answer: add 22 with $18.55  divide 50%

Step-by-step explanation:

As per linear equation, the equation to find the price of the shoe is: (11 + 0.5x) = 18.55.

The price of the shoe before discount is $15.1.

What is a linear equation?

"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, 'x' is a variable, 'A' is a coefficient and 'B' is constant."

Given, the price of the shirt before the discount is $22.

Let, the price of the shirt before the discount is $x.

Now, total price of the shirt and shoe $(22 + x).

Now, the total discount on shirt and shoe is

= $(22 + x) × 50%

= $(22 + x) × 0.5

= $(11 + 0.5x)

Now, (11 + 0.5x) = 18.55

⇒ 0.5x = 18.55 - 11

⇒ x = 7.55 ÷ 0.5

⇒ x = 15.10

Therefore, the price of the shoe before discount is $15.1.
