Suzanne can put up 20 feet of fencing in 64 minutes. How many minutes will it take her to put up 35 feet of fencing?

Answers

Answer:

112 minutes

Step-by-step explanation:

Suzanne can put up 20 feet of fencing in 64 minutes.

We need to find minutes it will take to put up 35 feet of fencing.

20 feet = 64 minutes

1 feet = (64/20) minutes

For 35 feet,

[tex]35\ feet=\dfrac{64}{20}\times 35\\\\=112\ minutes[/tex]

So, it will take 112 minutes to put up 35 feet of fencing.

Ahmad went on a bicycle tour. In the first two hours , he averaged 12 km/h; but in the next three hours he averaged 8 km/h;. A)Calculate the total distance covered b) , calculate his average speed for the whole journey

Answers

Answer: See explanation

Step-by-step explanation:

We are informed that Ahmad averaged 12 km/h in the first 2 hours. Total distance for the first 2 hours = 12km × 2 = 24km.

In the next three hours he averaged 8 km/h. The total distance for the next 3 hours = 8km × 3 = 24 km

A) Calculate the total distance covered.

This will be the distance covered for the 5 hours. This will be:

= 24km + 24km

B. Calculate his average speed for the whole journey.

This will be:

= Total distance covered / Total time taken

= 48km / 5

= 9.6 km/hour

Zach wants to buy a skateboard that costs $85. He currently has $15 saved. Zach plans to save d, dollars to have enough to buy the skateboard. Which equation represents the amount of money Zach still needs to buy the skateboard? *

Answers

Answer:

85 = 15 + d

d = 70

Step-by-step explanation:

Cost of a skateboard = $85

Zach savings = $15

Amount needed more to save = $d

Which equation represents the amount of money Zach still needs to buy the skateboard?

Total cost = available savings + more savings

85 = 15 + d

85 - 15 = d

70 = d

d = 70

Baba Yaga lost her broom somewhere between her hut and Bald Mountain, and wants to get it back. She calculates that with a tailwind of 2 km/h, she can fly from her hut to Bald Mountain in 6 hours. Baba Yaga starts her trip, finds her broom 40 km before Bald Mountain, and turns around and flies home. The entire journey takes 9 hours. Find the speed Baba Yaga flies in quiet weather (with no tailwind or headwind).

Answers

Answer:

The speed with which Baba Yaga flies in quiet weather (with no tailwind or headwind) is approximately 2.9 km/h

Step-by-step explanation:

In the question, we have;

The speed of the tailwind = 2 km/h

The time it takes Baba Yaga to the Bald Mountain = 6 hours

The location where Baba Yaga finds her broom = 40 km before Bald Mountain

The duration of the entire journey = 9 hours

Let 'v' represent the speed with which Baba Yaga flies in quiet weather (with no tailwind or headwind), we get;

(v + 2) × t = (v - 2) × (t - 9)

v·t + 2·t = v·t - 9·v - 2·t + 18

2·t = 18 - 9·v - 2·t

4·t = 18 - 9·v

t = 4.5 - 2.25·v

(v + 2) × 6 = (v - 2) × (t - 9) + 40

6·v + 12 = (v - 2) × (4.5 - 2.25·v - 9) + 40

6·v + 12 = (v - 2) × (-2.25·v - 4.5) + 40

With a graphing calculator, we have;

6·v + 12 + 2.5·v² - 0.5·v - 9 - 40 = 0

5·v² + 11·v - 74 = 0

Using the quadratic formula

v = (-11 ± √(11² - 4·5×(-74)))/(2·5)

v ≈ 2.9, or v ≈ -5.1

Therefore;

The speed with which Baba Yaga flies in quiet weather (with no tailwind or headwind), v ≈ 2.9 km/h

Write an equation for each line. A graph. Line k. Line m. Line p. Line r.

Answers

Answer:

line k:  y = x + 4

line m:  y = -2x + 4

line p:  y = -6

line r:  x = 1

Step-by-step explanation:

The equation for each line considering the graph is line k:  y = x + 4, line m:  y = -2x + 4, line p:  y = -6, line r:  x = 1

What is a line?

An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.

Calculate the slopes of the lines as shown below,

[tex]m = y_2 - y_1 / x_2 - x_1[/tex]

For line k, m = 0 - (-4) / -4 -0

m = -1

Thus, the equation of a line having slope -1 and coordinates (0, 4) can be written as,

[tex]y-y_1 = m(x- x_1 )[/tex]

y - 4 = -1(x-0)

y -4 = -x

y = -x + 4

Similarly, write the equation for lines m, p, and r,

line m:  y = -2x + 4

line p:  y = -6

line r:  x = 1
