If a triangle weighs 1 gram, how much does a square weigh? Can you find another pair of values that makes the hanger balance?

Answers

square weigh = x

x + x + x + 1 + 1 = x + 1 + 1 + 1 + 1 + 1

3x + 2 = x + 5

3x - x = 5 - 2

2x = 3

x = 3/2

x = 1,5

Anwser: 1,5 gram

The weight of square from the given figure is 1.5 grams.

Given that, a triangle weighs 1 gram.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the weight of each square is x grams.

Now, x+x+x+1+1 = x+1+1+1+1+1

⇒ 3x + 2 = x + 5

⇒ 3x - x = 5 - 2

⇒ 2x = 3

⇒ x = 3/2

⇒ x = 1.5 gram

Therefore, the weight of square from the given figure is 1.5 grams.

What was the mean Deviation of the number of pets?

A-1.02
B-1.053
C-1.087
D-1.12

Answers

C is the answer .....

The mean deviation of the number of pets Ramiro surveyed as shown in the table attached below is: D. 1.12

To find the mean deviation of the number of pets, the following steps would be taken:

Find the mean, which is sum of each frequency and score (fx) divided by the total number of pets. [tex]\mathbf{(\frac{\sum fx}{n} )}[/tex]Subtract the mean from each score, [tex]\mathbf{( x - \bar x)}[/tex]Sum the deviations together and divide by total number of pets.The formula for the mean deviation is given as: [tex]\mathbf{\frac{\sum f* |x - \bar x|}{n} }[/tex]

Mean deviation as solved in the table attached in the image below would be:

[tex]\mathbf{\frac{33.6}{30} = 1.12}[/tex]

Therefore, the mean deviation of the number of pets Ramiro surveyed as shown in the table attached below is: D. 1.12

The copy shop charges a $5 set-up fee for each copying job and $0.05 per page. 1. Jaylyn takes a 10-page report to the copy shop to be photocopied. How much will that job cost Jaylyn? It would cost Jaylyn (put the money sign in your answer or it will be wrong)

Answers

it will cost jaylyn $5.50 to print her 10-page report.

y = 0.05x + 5, and we can substitute x for 10. there are ten pages, and each page costs 5 cents, so we multiply 0.05 x 10. the final answer is 0.5, and once we add the set-up fee ($5) the total is $5.5.

so, 5.5 = 0.05(10) + 5.
It will cost one dollar
