WILL MARK BRAINLIEST PLS HELP. Fill in the table by following the rules provided for each backpack.

Answers

Answer:

See complete answer

Step-by-step explanation:

Backpack 2 is 2x, 2y, so double each number:

(0,2) = (0, 4)

(8,2) = (16, 4)

(6,5) = (12, 10)

(2,5) = (4, 10)

(0,2) = (0,4)

Backpack 3 is x + 8, y - 2 so add 8 to x and subtract 2 from y:

(0,2) = (8, 0)

(8,2) = (16, 0)

(6,5) = (14, 3)

(2,5) = (10, 3)

(0,2) = (8, 0)

Backpack 4 is x, 2y, so keep the same x and multiply y * 2

(0,2) = (0, 4)

(8,2) = (8, 4)

(6,5) = (6, 10)

(2,5) = (2, 10)

(0,2) = (0,4)

Simplify each expression involving signed numbers.

-7 – 2 =
12 + (-4) =
-8(-6) =

18/-3=

Answers

Answer:

-5 , 8 , 48 , -6

Step-by-step explanation:

-7- -2 = -5

This complies with the rule that 2 negatives make a positive.

12 + (-4) = 8

You just ignore the brackets.

-8(-6) = 48

The -8 next to the bracket with no symbol means you need to multiply, and again 2 negatives make a positive.

18/-3 = -6

As the 18 is not negative, but -3 is, the answer is also a negative because one negative and one positive make a negative!

Hope this helps and have a good day!

About 71% of Earth’s surface is covered in water.

Question 1
Part A

If Earth's surface area is about 196,900,000 square miles, about how many square miles are covered in water?

Enter the correct answer in the box.
Part B

About what percent of Earth’s surface is not covered in water? How many square miles is this?

Enter the correct answers in the boxes.

Answers

Answer:

A. 139,799,000 square miles

B. 57,101,000 square miles

Step-by-step explanation:

71% ÷ 100 = 0.71

0.71 x 196,900,000 = 139,799,000

100 - 71 = 29

29 ÷ 100 = 0.29

0.29 x 196,900,000 = 57,101,000

another way; knowledge of A

196,900,000 - 139,799,000

= 57,101,000

Read the passage about Ötzi the Iceman.

Half an hour after Ötzi dined, the killer came along and shot him in the back from a distance of almost 100 feet. The arrow went under his left armpit . . . a wound that would have been quickly fatal and probably not treatable even in modern times, especially where it happened. By the angle of the wound, he was either shot from below and behind, or he had been bent forward when he was hit from above and behind.

During a sale, a store offered a 15% discount on a TV that originally sold for $900. After the sale, the discounted price of the TV was marked up by 15%. To the nearest whole number, what percent of the original price was the price after markup?

Answers

Answer: 98%

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

Explanation:

The customer saves 15%, but still pays the remaining 85%. The two percentages add to 100%.

85% of $900 = 0.85*900 = 765

After the 15% discount is applied, the customer would pay $765

---------

Then after the sale, the price is marked up by 15%

This means we'll multiply by 1.15 to indicate a 15% increase

1.15*765 = 879.75

Notice that we don't get back to the original price (900) even though we increased by the same percentage as before. This is because 15% of a smaller number is a smaller amount; ie we have a smaller increase compared to the decrease earlier.

---------

Afterwards, divide the value 879.75 over the original price of $900

879.75/900 = 0.9775

Move the decimal point two spots to the right to end up with 97.75%

That percentage rounds to 98% when rounding to the nearest whole percent.

Pete wants to buy a new gaming controller that is on sale. The controller costs $105 and is on sale for 35% off. If the sales tax is 10.1%, how much will he pay for the controller?

The final price is: $_________

Answers

Answer:

The final Price is: $75.14

Step-by-step explanation:

you first have to do -=- which means /105=35%/100

then you would do 105x35=3675/100=36.75

then Subtract 105-36.75=68.25.

The next step is to do -=- /68.25=10.1%/100

you would multiply 68.25 and 10.1 and get 689.325 the you would divided that by 100 and get 6.89325 then you would add 68.25 and 6.89325 and get 75.14.
