If an iceberg has a mass of 1800 kg and a volume of 19000 m3, what
is its density?

Answers

Answer:

≈0.0947 kg/m^3

Step-by-step explanation:

p = density

m = mass

v = volume

Formula for density :

p = m/v

We know the mass and volume, so we can simply substitute our values into the equation:

p = m/v

p = 1800kg / 19000 m^3

p = ≈0.0947 kg/m^3

What strategy would be the best to solve this problem? Ann-Marie bought apples. She kept one-third for herself and gave the rest to 4 friends. Each friend got 2 apples. How many apples did Ann-Marie buy? A. guess, check and revise B. work backwards C. use a formula D. look for patterns

Answers

Answer:

D. Look for patterns

Step-by-step explanation:

To solve :

Assume number of apples bought = x

Fraction kept = 1/3 of x

Fraction shared = (x - x/3) = (3x - x) /3 = 2x/3

Number of people who shared (2x/3) = 4 with each getting 2

Total number shared = 4 * 2 = 8

Fraction shared = total shared

2x/3 = 8

Multiply both sides by 3

(2x/3) * 3 = 8 * 3

2x = 24

x = 12

Hence, Anne-Marie purchased 12 apples

Andrea is shopping for items for her pet sitting business because the store is having a sale where everything in the store is 5% off. Andrea buys a cat carrier for $39.99 and a cat tower for $19.99. She has a coupon for an additional 15% off on the cat tower. Before tax, Andrea estimates that her total, after discounts, will be about $54. Determine if Andrea has estimated correctly.

Answers

Given:
cat carrier : 39.99
cat tower: 19.99
1st discount : 5%
2nd discount: 15% - cat tower

39.99 * 5% = 1.99
39.99 - 1.99 = 38

19.99 * (5% + 15%) = 19.99 * 20% = 3.99
19.99 - 3.99 = 16

38 + 16 = 54

Andrea estimated correctly.

Answer:

A. Yes, Andrea has estimated correctly

the median is truly the middle of the data set. But the mean describes the average i want you to decide so i wont get this wrong. Thus, is the mean more important than the median according to this information?

Solve the following equation: 6y – 20 = 2y – 4.A. y = 3
B. y = 16
C. y = 4
D. y = 2

Answers

6y - 20 = 2y - 4

Add 20 on both sides

6y - 20 + 20 = 2y - 4 + 20
6y = 2y - 4 + 20
6y = 2y + 16

Subtract 2y on both sides.

6y - 2y = 2y - 2y + 16
6y - 2y = 16
4y = 16

Divide 4 on both sides.

4y/4 = 16/4
y = 16/4

y = 4.

Your final answer is C. y = 4.

6y-20 =2y-4

ans: y=4

hope it would help
