Bob is reading a 445 page book. He has already read 157 pages. If he reads 24 pages a day, how long will it take him to finish t
Sever21 [200]

Answer:

12 days

Step-by-step explanation:

Set up an equation with y = mx + b, where m is the rate and b is the y-intercept (starting value)

Let x represent how many days it takes and y represent how many pages he read:

445 = 24x + 157

Solve for x:

288 = 24x

12 = x

So, it will take him 12 days to finish the book

Tom has 2 1/2 times as many cards as Harry. Together they have 98 cards. How many cards do they each have?
USPshnik [31]

Answer:

Tom has 70 cards, and Harry has 28 cards.

Step-by-step explanation:

Let h = number of cards Harry has.

Then the number of cards Tom has is 2 1/2 * h = 2.5h.

Together they have 2.5h + h = 3.5h number of cards.

Together they have 98 cards.

3.5h = 98

h = 98/3.5

h = 28

Harry has 28 cards.

Tom has 2.5h = 2.5 * 28 = 70

Answer: Tom has 70 cards, and Harry has 28 cards.

soldier1979 [14.2K]
--------------------------------------------------------
Find Radius :
--------------------------------------------------------
Base area = πr²
169π = πr²
r² = 169
r = √169
r = 13 cm

--------------------------------------------------------
Find height :
--------------------------------------------------------
Height = 13 + 4
Height = 17 cm

--------------------------------------------------------
Find Volume :
--------------------------------------------------------
Volume = πr²h
Volume = π(13)²(17)
Volume = 9025.8 cm³

--------------------------------------------------------
Answer: Volume = 9025.8 cm³
