Christopher just found beautiful yarn for 20% off. He can make one scarf from 2/3 of a ball. If Christopher buys 12 balls of yarn, how many scarves can he make?

Answers

Answer 1

Answer:

Answer: There are 18 scarves which he can make.

Step-by-step explanation:

Since we have given that

Number of balls Christopher bought = 12

From $(2)/(3)$ of a ball, he can make 1 scarf.

So, from 12 balls , number of scarves he can make is given by

$\frac{\text{Number of balls }}{\text{Number of balls to make 1 scarf}}\n\n=(12)/((2)/(3))\n\n\n=(12* 3)/(2)\n\n=(36)/(2)\n\n=18$

Hence, there are 18 scarves which he can make.

Answer 2

Answer: He can make 18 scarves.

Multiplying numerators and denominators to get the LCD in all fraction denominators

= 38−21×24×2

Then rewriting the equation with the equivalent fractions

= 38−428

With like denominators we can operate on just the numerators

= 3−4 2/8

=−39/ 8

Simplifying the answer

= − 39/8

= − 4 7/8

4x + 10= 2x - 6

Answers

4x + 10= 2x - 6
Subtract 2x on both sides

4x - 2x + 10 = 2x - 2x - 6

4x - 2x + 10 = -6

2x + 10 = -6

Subtract 10 on both sides

2x + 10 - 10 = -6 - 10

2x = -6 - 10

2x = -16

x = -8

If a sequence is defined recursively by f(0) = 2 andf(n +1) = -2f(n) + 3 for n ≥ 0, then f(2) is equal to

Answers

If you would like to know how much is f(2), you can calculate this using the following steps:

f(0) = 2
f(n+1) = - 2 * f(n) + 3
f(1) = - 2 * f(0) + 3 = - 2 * 2 + 3 = - 4 + 3 = - 1
f(2) = - 2 * f(1) + 3 = - 2 * (-1) + 3 = 2 + 3 = 5

The correct result would be f(2) = 5.

This box has the same length , width, and height as the 2 basketballs. Which expression gives the volume of the empty space encircling the basketballs inside the box?

Answers

Answer:

$4,608(6- \pi)\ cm^(3)$

Step-by-step explanation:

we know that

The volume of the empty space encircling the basketballs inside the box is equal to the volume of the box minus the volume of the two basketball inside the box

The volume of the box is equal to

$V=LWH$

in this problem we have

$L=2*24=48\ cm$

$W=24\ cm$

$H=24\ cm$

substitute

$V=48*24*24=27,648\ cm^(3)$

The volume of the two basketball inside the box is equal to

$V=2*(4)/(3) \pi r^(3)$

n this problem we have

$r=24/2=12\ cm$

substitute

$V=(8)/(3) \pi 12^(3)$

$V=4,608 \pi\ cm^(3)$

The expression is equal to

$(27,648-4,608 \pi)\ cm^(3)$

$4,608(6- \pi)\ cm^(3)$
