Referring to the figure, the circle shown is drawn on grids. Find
A ÷ r and A ÷ r2.
a. 18.8, 4.6 c. 7.9, 3
b. 19.8, 4.9 d. 15.8, 3.2

Answer:

1. A=80. wl=a that is the same as 10x8=80

2.A=17. 4·8.52=17

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:

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.

Answer:

300

Step-by-step explanation:

Let the total students be x.

Students absent for two or more = 32%

(on adding percentage of both 2 and 3 or more)

32/100x = 96

X = (96*100)/32

X = 300

Answer:

the answer is 2

Step-by-step explanation:

x= 2

Answer:

-13

Step-by-step explanation:

You cant subtract so do the opposite

A shipment of 1.5 pounds of moonstone crystals was divided into 6 equal bags. Each bag would weigh 0.25 pounds, which is the same as 4.0 pounds.

To solve this problem, we can use the following equation:

total weight / number of bags = weight of each bag

In this case, the total weight is 1.5 pounds and the number of bags is 6. So, the weight of each bag is:

1.5 pounds / 6 bags = 0.25 pounds per bag

Since 0.25 pounds is the same as 4.0 pounds, each bag would weigh 4.0 pounds.

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.

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.

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.

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.

Therefore, Question 1 and Question 2 are correct.

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)

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

Answer: Option A is the correct answer

Step-by-step explanation: I took the test and got it right

The total weight of the two animals is 1.19 x 10³ lbs. So the correct option is B.

Given approximate weights of the two animals are as:

1. 5.12 x 10² lbs

2. 6.8 x 10² lbs

We need to find the total weight of the two animals.

Step 1: Add the weights together:

5.12 x 10² lbs + 6.8 x 10² lbs

Step 2: Perform the addition:

(5.12 + 6.8) x 10² lbs

11.92 x 10² lbs

Step 3: Express the result in scientific notation with the correct number of significant digits:

The first number, 11.92, has three significant digits. To maintain three significant digits in the final answer, we can express it as 11.9 (rounding to the nearest tenth) and adjust the exponent accordingly:

11.9 x 10² lbs

This matches option 2 from your provided answers:

2. 1.19 x 10³ lbs.

So, the correct answer is: 1.19 x 10³ lbs.
