Answer 1

They are right triangles so you can use the Pythagorean theorem.

A = sqrt(5^2+3^2)

A = sqrt(25+9)

A = sqrt(34) (exact answer)

As a decimal it would be: 5.8

B = 45 = sqrt( 20^2 + b^2)

B^2 = 45^2-20^2

B^2 = 2025-400

B^2 = 1625

B = sqrt(1625)

B = 5sqrt(65) exact answer

As a decimal : 40.3

Answer 2

Answer:

Side length A is 5.8cm

Side length B is 40.3cm

Step-by-step explanation:

To find A:

5^2+3^2=34

square root of 34= 5.83...

round to 5.8

To find B:

45^2-20^2= 1625

square root of 1625= 40.3112...

round to 40.3

quart and pint

Answers

Answer:

3 pints or 1.5 quarts

Step-by-step explanation:

1 quart has 2 pints, so each pitcher holds 4 pints -- 12 pints all together. So 15-12 = 3 pints that will not fit into the pitchers. 3 pints is equal to 1.5 quarts!

A box contains 12 cereal bars. The empty box weighs
1.75 oz. The box and the bars weigh 18.55 oz. what is the weight of each cereal bar?

please answer asap!!!

Answers

Answer:

1.4oz

Step-by-step explanation:

You subtract the weight of the box and the bars with the empty box. Then divide the answer you got from that, with 12 and you get your answer.

The weight of each cereal bar is 1.4 oz.

What is an equation?

"It is a statement which consists of equal symbol between two mathematical expressions."

For given example,

Let 'x' be the weight of single cereal bar.

A box contains 12 cereal bars.

The empty box weighs 1.75 oz.

The box and the bars weigh 18.55 oz.

This means the the total weight of the box is:

total weight = weight of the empty box + weight of 12 cereal bars

So, we get an equation,

⇒ 18.55 = 1.75 + ('x' × 12)

We solve above equation to find the weight of each cereal bar.

⇒ 18.55 = 1.75 + 12x

⇒ 12x = 16.8

⇒ x = (16.8)/12

⇒ x = 1.4 oz.

Therefore, the weight of each cereal bar is 1.4 oz.

How many 1/9's in 31

Answers

There are a total of 279 1/9s in 31.

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.

To find out how many 1/9's are in 31, you can divide 31 by 1/9.

This can be simplified by converting the division of a fraction to multiplication with its reciprocal:

31 ÷ (1/9) = 31 × (9/1)

Simplifying the expression on the right side gives:

31 × 9 = 279

So there are 279, 1/9's in 31.
