Next time, the rabbit from the previous problem start at 10 where on the number line can he be after the same three jumps?

Previous problem : A rabbit started at point 0 and made 3 jumps: a jump of 4 units, then a jump of 2 units, and then a jump of 1 unit. We do not know the direction of either jump. What are all the possible numbers can this rabbit be now?

Answers

It should be noted that since the rabbit from the previous problem started at 10, it would be at 17 units on the number line after the same three jumps.

What is a number line?

A number line is a type of graph with a graduated straight line which comprises both positive and negative numerical values. From the previous problem, the total distance covered by the rabbit is given by:

Total distance = 4 units + 2 units + 1 unit

Total distance = 7 units.

Since the second point is at 10 units and the open circle arrow points to the right of the number line, the rabbit would cover 7 more distance from this point:

Total distance = 10 units + 7 units

Total distance = 17 units.

Enzo is buying wallpaper. He can choose one colour, one texture and one thickness for his wallpaper. At his local DIY store, Enzo can choose from 27 different colours 14 different textures. The total number of options available to enzo for his wallpaper is 2268. Work out the number of different wallpaper thicknesses that enzo can choose from.

Answers

Answer:

6 different wallpapers

Step-by-step explanation:

Given

[tex]Colours = 27[/tex]

[tex]Textures = 14[/tex]

[tex]Total = 2268[/tex]

Required

Determine the number of different wallpapers he can choose from

From the question, he can choose 1 from 27 colors;

The number of ways is:

[tex]Colours = ^{27}C_1 = \frac{27!}{(27 - 1)!*1!} = \frac{27!}{26!*1!} = = \frac{27*26!}{26!*1} = 27[/tex]

From the question, he can choose 1 from 14 textures;

The number of ways is:

[tex]Textures = ^{14}C_1 = \frac{14!}{(14 - 1)!*1!} = \frac{14!}{13!*1!} = \frac{14*13!}{13!*1} = 14[/tex]

Assume the total number of wallpapers is x and he can only select 1.

The number of ways of selection is:

[tex]Wallpapers = ^{x}C_1 = \frac{x!}{(x - 1)!*1!} = \frac{x* (x - 1)!}{(x - 1)!*1!} = x[/tex]

So, the total selection is:

[tex]Colours * Textures * Wallpapers = Total[/tex]

[tex]27 * 14* x= 2268[/tex]

[tex]378* x= 2268[/tex]

Divide both sides by 378

[tex]\frac{378* x}{378}= \frac{2268}{378}[/tex]

[tex]x= \frac{2268}{378}[/tex]

[tex]x= 6[/tex]

Hence, the number of different wallpaper is 6

Alto and Brian both ordered the same size pizzas and Marco's Pizza;

however, they ordered different toppings. Marco's charges an additional

fee for toppings, but all toppings cost the same. Alto got pepperoni,

banana peppers, and black olives on his pizza for a cost of $15.74. Brian

order mushrooms and eggplant of his pizza and paid $14.49. Using this

information, write an equation for the cost of a pizza, C, as a function of

the toppings, t, ordered. *Hint: slope intercept form and you will need the

slope formula

Answers

Answer:

Cost of pizza = 1.25x + 11.99

Step-by-step explanation:

Since Toppings cost the same and the pizza orders are of same size :

Alto ordered for 3 Toppings + pizza = 15.74

Brian ordered for 2 toppings + pizza = 14.49

Hence the cost per topping and pizza could be found :

Cost per topping :

15.74 - 14.49 = 1.25

Hence, slope = 1.25

The intercept, c represents the cost of pizza alone :

Cost of pizza + 2 Toppings = 14.49

Cost per topping = 1.25

Cost of pizza = 14.49 - 2(1.25)

Cost of pizza = 14.49 - 2.50 = 11.99

Expressing in slope - intercept form :

y = mx + c

m = slope ; c = intercept

Cost of pizza = 1.25x + 11.99

A plant currently measures 5.5 inches tall and will grow at a rate of 1 inch per week. Andrew wants to graph this information for his Science Fair project. If x represents the number of weeks and y represents the height of the plant, which choice below correctly describes the y-intercept in this relationship?
(5.5, 0)

(0,1)

(0, 5.5)

(1, 5.5)

Answers

Answer:

0, 5.5

Step-by-step explanation:

when they ask for a y-intercept, x is always zero, so now we eliminate two of the answers, and we will only have (0, 1) or (0, 5.5). At the beginning of the question it said a plant is currently at 5.5, so it started as 5.5 (0, 5.5)

so THE ANSWER IS  (0, 5.5)
