Julie sees a ride that spins 10 turns each minute. She says it will spin 40 turns in 4 minutes. Is Julie correct? Explain.

Answers

Answer:

yes

Step-by-step explanation:

1 minute = 10 turns

4 minutes = 40 turns

• This is direct proportion. As one side increases by a value so must the other. In this case 1 min has become 4 mins. This has been multiplied by 4. So 10 must be multiplied by 4 too. 4 × 10 = 40 turns.

Answer: Yes she is correct

A pack of 50 sheets of paper costs $1.10. What is the cost per
sheet of paper? Did you multiply or divide to find your answer?
a. $0.022, divide c. $55, multiply
b. $0.022, multiply d. $55, divide

Answers

Answer: Choice A

$0.022, divide

======================================================

Work Shown:

50 sheets = 1.10 dollars

50/50 sheets = 1.10/50 dollars

1 sheet = 0.022 dollars

In the second step, I divided both sides by 50 to get the "50 sheets" to turn into "1 sheet". The result of 0.022 dollars is equivalent to 2.2 cents; so the unit cost is a little over 2 cents per sheet.

A is going to be your answer for this question .

Based on the lesson, identify the first operation needed to solve the equation.
11 x+3=3
A. subtraction
B. division
C. addition
D. multiplication

Answers

Answer:

Subtraction

Step-by-step explanation:

Since you have 11x + 3 = 3, you need to get rid of the +3. To do that, you need to do the ooposite of what the sign says which in this case is addition. The opposite of addition is subtraction.

Akio has 27 blankets and 18 flashlights to use in emergency relief kits for communities in need. He will put the same number of blankets and the same number of flashlights in each kit. He wants to use all the blankets and flashlights. What is the greatest number of emergency relief kits Akio can make?

Answers

Answer:

6

Step-by-step explanation:

The answer Is 6

Answer:

9

Step-by-step explanation:

We can make an equation out of this

So if he has 27 blankets, and 18 flashlights, he will need to divide evenly amongst the kits.
The equation would be

z=x+y, where x is the amount of blankets, and y is the amount of flashlights.

to find this, we need to find what 27 is divisible by, and what 18 is divisible by.

27 - 27, 9 , 3, 1

18 - 18, 9, 6, 2, 3, 1

Now, 18 and 27 are both divisible by 9

18/9=2

27/9=3

So we can make a total of 9 emergency kits, with each kit having 3 blankets and 2 flashlights

Hope this helps!!^^

Answer: Question 1: For season 1 it is 1,10 for the grid and for season 2 it is 2,8 Question 2: 29, is 14 in the gap to 38 and the rest count by 2s or 10s.

and the season 3 is 3,7

See more below......

Step-by-step explanation:

Question 1: Use a coordinate grid to answer the question.

Coordinate grid is a rectangular plane where the intersection of horizontal and vertical lines forms a grid network.

Question 2: Is you count by 2s or 10s.

2s are you add 2 to get the next number.

10s are counting multiple groups of 10 in a faster way.

What are the characteristics of the graph of the inequality x < 4.5 ?

The ray will move to the left.
It will use a closed circle.
It will use an open circle.
The ray will move to the right.

Answers

Answer:

The ray will move to the left and it will use an open circle.

Step-by-step explanation:

The ray will move to the left because x < 4.5 is the same thing as -∞<x<4.5,

It will be a open circle because x is not less than or equal to 4.5, it is this: x is less than 4.5.

Describe and correct the error a student made when graphing the linear equation y = - 6.

Answers

Answer:

The error is in computing the y intercept. It should be at (0, -6) not (0, 6)

Step-by-step explanation:

The equation of the line is

[tex]-\frac{3}{4} x - 6[/tex]

y intercept is at point x = 0

When x = 0,

[tex]y = -\frac{3}{4} x - 6\\\\y = 0 - 6 \\\\y = -6[/tex]

So y intercept is at point (0, -6)

If we plot a second point 3 units down and 4 units right we should get the point 0 + 4, -6 - 3) = (4, -9)

Plugging this into the original correct equation satisfies the equation

[tex]y = -\frac{3}{4} x - 6\\\\y = -\frac{3}{4} (4) - 6 \\\\y = -3 -6 = -9 \\\\[/tex]

So we can see that the line does pass through (4, -9)

Answers

Answer: 40

Step-by-step explanation:

4 x (x)/4 = 10 x 4 (4 ÷ 4 = 1, so they'll cancel out)

10 x 4 x 1 = 40

Step-by-step explanation:

so, the whole thing starts out as

x/4 = 10

the next 2 steps are written by your teacher :

multiply both sides now by 4

4 × x/4 = 10 × 4

on the left side (as your teacher stroke through)

4 / 4 = 1

leaving x all by itself.

on the right side

10 × 4 = 40

and you get

x = 40

and there is your result.
