ONE EIGHTH OF TONYS BOOKS ARE MYSTERY BOOKS. HE HAS 3 BOOKS. HOW MANY BOOKS DOES TONY HAVE IN ALL

Mathematics
1 answer:
LekaFEV [45]2 years ago

Answer:  If he has 3 mystery books, and those are 1/8 of his whole collection, he has 24 books.

Step-by-step explanation:

3 = 1/8 × x

multiply both sides by the reciprocal of 1/8 which is 8/1 ("flipped fraction")

8 × 3 = 8/1(1/8) x  <em>When you multiply a fraction by its reciprocal, it produces 1, so it "cancels" in the multiplication</em>

<em>24 = x </em>

<em>This may seem complicated, but understanding the process will help you solve more complicated questions like this in the future, I hope.</em>

Answer:

x = 11

Step-by-step explanation:

Raising both sides to the fifth power, we get:

27(x - 2) = 3⁵

x - 2 = 3⁵ / 27

x - 2 = 3⁵ / 3³

x - 2 = 3⁽⁵⁻³⁾ = 3² = 9

x = 11

I NEED HELP PLSSSSSSSS
AVprozaik [17]

Answer:

X >>>>> Y

–1 >>>> 16

0 >>>>> 8

1 >>>>> 4

2 >>>>> 2

3 >>>>> 1

Step-by-step explanation:

From the question given above,

y = 8 × (½)ˣ

When x = –1, y =?

y = 8 × (½)ˣ

y = 8 × (½)¯¹

y = 8 × 2

y = 16

When x = 1, y =?

y = 8 × (½)ˣ

y = 8 × (½)¹

y = 8 × ½

y = 4

When x = 2, y =?

y = 8 × (½)ˣ

y = 8 × (½)²

y = 8 × ¼

y = 2

When x = 3, y =?

y = 8 × (½)ˣ

y = 8 × (½)³

y = 8 × ⅛

y = 1

SUMMARY:

X >>>>> Y

–1 >>>> 16

0 >>>>> 8

1 >>>>> 4

2 >>>>> 2

3 >>>>> 1

What is the interquartile for this set of data? 11,19,35,42,60,72,80,85,88
exis [7]

Answer:

55.5

Step-by-step explanation:

find the median - in this case it's 60

then group the upper and lower halves of the data:

(11, 19, 35, 42) 60 (72, 80, 85, 88)

now we find the medians of those sets:

35 + 19/2 = 54/2 =27

80 + 85/2 = 165/2 = 82.5

then subtract those two medians to find the interquartile:

82.5 - 27 = 55.5
