Three people are kayaking. They all started at the same point and rowed in the same direction for 20 minutes. Laura rowed 7/8 mile
Daniel rowed 1/2 mile
Annabelle rowed 1/4 mile
Part A:
Did Laura row a distance greater than, less than, or equal to the combined distance of Daniel and Annabelle?

Answers

We can make everything have the same denominator so we can add, subtract, and compare them:

The common denominator between 2, 4, and 8, is 8.

7/8 = 7/8

1/2 = 4/8

1/4 = 2/8

The question is if Laura rowed more, less, or the same to the combined distance of Daniel and Annabelle:

Laura : 7/8

Daniel: 4/8

Annabelle: 2/8

4/8 + 2/8 = 6/8

So Daniel and Annabelle's distance combined is 6/8, which is less than Laura's:

7/8 > 6/8.

This means that Laura rowed more than Daniel and Annabelle.

On Serena's tenth birthday,her mom was 3 times Serena's age.How old will Serena and her mom be when her mom's age times 0.5 will equal Serena's age?

Answers

Serena 10th birthday means she was 10 and her mom was 3 times as old which is 30. They are 20 years apart so 0.5 or 1/2 her mom's age will be Serenas age when her mom is 40 and she is 20

Answer:

15 yrs

Step-by-step explanation:

10 x 3 = 30

30 x 0.5 = 15.0

A cylinder is full at 471 cm³ and has a radius of 5 cm. It currently contains 314 cm³ of water.What is the difference between the height of the water in the full cylinder and the height when 314 cm³ of water remains in the cylinder?”

Use 3.14 to approximate pi.

Answers

The answer is 2 cm

Step 1. Calculate the height of full cylinder (h1 = ?)
Step 2. Calculate the height of cylinder that contains 314 cm³ of water (h2 = ?)
Step 3. Find the difference between the height of the water in the full cylinder and the height when 314 cm³ of water (h1 - h2 = ?)

The volume (V) of the cylinder with radius r and height h is:
V = π * r² * h
So, h = V / (π * r²)

Step 1.
h1 = ?

V1 = 471 cm³
r = 5 cm
π = 3.14

h1 = V1 / (π * r²)
h1 = 471 / (3.14 * 5²)
h1 = 471 / (3.14 * 25)
h1 = 471 / 78.5
h1 = 6 cm

Step 2.
h2 = ?

V2 = 314 cm³
r = 5 cm
π = 3.14

h2 = V2 / (π * r²)
h2 = 314 / (3.14 * 5²)
h2 = 314 / (3.14 * 25)
h2 = 314 / 78.5
h2 = 4 cm

Step 3.
h1 - h2 = 6 - 4 = 2 cm

polynomial that represents a difference in cubes.

x³ - 64 = 0
x³ = 64
∛x³ = ∛64
x = 4

Correct Steps for factoring the polynomial 5x³ - 40
5(x³ - 8)
5((x)³ - (2)³)
5(x - 2)(x² + 2x + 4)

To check:
5(x - 2)(x² + 2x + 4)
(5x - 10) (x² + 2x + 4)
5x(x² + 2x + 4) - 10(x² + 2x + 4)
5x³ + 10x² + 20x - 10x² - 20x - 40
5x³ + 10x² - 10x² + 20x - 20x - 40
5x³ - 40

Difference of cubes: a³ - b³

A) x³ - 64 = x³ - 4³

In B, 4 is not a cube number.

In C, this is the sum of a cubes. 8x³ + 27 = (2x)³ = 3³

In D, 4 is not a cube number.

Your answer is A.

Question #6

5x³ - 40
5[x³ - 8]
5[x³ - 2³]

Note: x³ - y³ = (x-y)(x² + xy + b²)

5[(x-2)(x² + 2x + 2²)]
5[(x-2)(x² + 2x + 4)]

Your answer is B.

how do i do 1 only? i honestly don't know what to do. first one answer is brainliest. oh and if you mind plz send me the answer for 1 b and c.thx

Answers

Since they all have the same denominator you add them, first you can add the whole numbers,
2+1+3=6
1/3+2/3= 3/3 or 1
Plus 3/3 or 1
So, now you have 2+1+3+1+1
The answer is 8
