Blank 2: __________________


PLEASE DONT ANSWER IDK OR SOMETHING LIKE THAT JUST FOR POINTS PLEASE!

Answers

Answer 1

Answer:

Elena's running speed is 5 miles/hour

Explanation:

The speed is defined as the covered distance per unit time

In the problem, we have:

The distance covered is the length (circumference) of the circular track which is given as  of a mile.

We are also given that she completes each lap (she completes  of a mile) in  of an hour

To get her speed, we will divide the distance covered by the time taken to cover this distance

This is done as follows:

speed =  miles/hour

This means that:

Elena can run 5 miles each hour

Let f(x)=7x+5 and g(x)=x-1. If h(x)=f(g(x)), then what is the inverse of h(x)

Answers

i dont really know how to explain it so i just solved it (the answer is boxed) but i hope this helps !
ANSWER: x= 6/7

EXPLANATION:

Subtract 5 from both sides (7x+5-5=-1-5)
Simplify= (7x=-6)
Divide both sides by 7 (7x divide by 7 -6 disguised by 7)
Simplify (x= -6/7) x equals negative six over seven

The perimeter of a rectangle is less than 10 inches. The length is x and the width is x − 5. If the solution is x < 5, then the length is less than 5. Is this a viable solution?

1. viable
2. non-viable

Answers

Answer:

Yes and No. The length must be less than 5.

But there is a practical limit to how the width is calculated.

So No.. This solution is not completely viable.

Step-by-step explanation:

If the length is almost 4, for example, the width must be between a bit more than 0 and less than or equal to 1. Using x<5 -5 to compute the width is not viable.

Ramiro did a survey of the number of pets owned by his classmates, with the following result

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

Hanna says you cannot represent the fraction One-fourth on the number line.

A number line going from 0 to 1 with 8 equal spaces between 0 and 1.

Which statement best explains Hanna’s thinking?
Hanna is correct. The space between consecutive integers is divided into eight parts and not four. You cannot represent One-fourth on the line.
Hanna is correct. The number line stops at 1, and you need to be able to have 4 on the graph to graph One-fourth.
Hanna is not correct. You can graph One-fourth if you extend the number line to 4.
Hanna is not correct. The fraction One-fourth is equal to 2/8, so you can graph it on the second tick mark to the right of zero.

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 is a expression? What is a mathematical equation?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Andre who drank 1.5 liters of water he brought. He drank 80% of his entire hike.

Assume that he drank [x] liters of water. Then -

x = 80% of 1.5 liters

x = (80/100) x 1.5

x = 8/10 x 1.5

x = 1.2 liters

Therefore, Andre drank 1.2 liters out of 1.5 liters of water.
