Answer:

neither

Step-by-step explanation:

exponent means to multiply the number which has the exponent on it to itself like if 2 has the exponent 3 then that means 2 x 2 x 2

please make me the brainliest!

Elena is correct. Because the number 28 is smaller and above the number two, that means it is the exponent. The exponent, or the power, tells you how many times you multiply the number by itself. For example 2 to the 3rd power or 2 with a small 3 above it would be 2 x 2 x 2 which is 8 instead of 2 x 3 which is 6. I hope this helped you and good luck!

A) 24 cm2
B) 16 cm2
C) 40 cm2
D) 18 cm2

Answers

Answer:

C) 40 cm²

Step-by-step explanation:

area of top triangle = 1/2 x 8 x 6 = 24 cm²

area of bottom triangle = 1/2 x 8 x 4 = 16 cm²

24 cm² + 16 cm² = 40 cm²

C would be the answer this is the correct answer because it makes most sense and also that’s correct because

The area of the top is :1/2x8x6=24 cm
Next!!

The area of the bottom is:1/2x8x4=16cm
Next!!
24 cm +16 cm = 40cm

Brenda pours laundry detergent from a bottle into the cap and then into the washing machine. Every time she fills the cap, the amount of detergent in the bottle changes by -0.26 liters. She fills the cap 3 1/4 times in all. John has a different bottle of detergent that is the same size. Every time he fills his cap, the amount of detergent in his bottle changes by -0.21 liters. He fills his cap 2 5/6 times in all. What was the total change for Brenda's bottle? What was the total change for John's bottle? Write as a decimal.

Answers

Brenda’s Bottle answer:

3 1/4 = 13/4 in improper fraction form.

13/4*-0.26 = -0.845. This is the difference in the change.

John’s Bottle answer:

2 5/6 = 17/6 in improper form

17/6*-0.21 = -0.595 in difference.

Answers

Answer:

Step-by-step explanation:

Part 1

$6.84 + $4.88 + $8.32 + $4.98 = $25.02

The total cost of the steaks comes to $25.02.

Part 2

2 × 20 = 40

40 - 25.02 = 14.98

1.25 is 5% of 25.02

14.98 - 1.25 = 13.73

The family gets $13.73 back in change.

Part 3

6.84 ÷ 12 = 0.57

4.88 ÷ 8 = 0.61

8.32 ÷ 16 = 0.52

4.98 ÷ 6 = 0.83

Part 4

0.83 - 0.52 = 0.31

They should buy larger steaks to share because the larger steaks are $0.31 cheaper than the smaller steaks.

1. the total cost is $25.02

You have to add all the cost of the family had which is $6.84+$4.88+$8.32+$4.98

2.they would get $13.73 back

I got it by the $25.02 from the last one and add with tax which was 5% so I then in total of $26.271 and since this is money I rounded it up to $26.27. After I got that I subtracted the $40 since they use 2 $20. $40-$26.27=$13.73

3. I think it would be the estimate of 0.60 per ounce

I got that by dividing the total cost and the all the ounces which I got the estimate of 0.60

4. I think they should order the larger steaks than the smaller steaks to share since it would be for one family.

I am sorry if one of them are wrong but I hope this could help you.
