Since there are 3 and assuming that they're the same size each radius is 1.5, as is the radius of the base of the cylinder. So you have to figure out the volume of one of the balls and multiply it by three. Formula: (4/3) * pi * radius^3. The volume of all three is 42.42. Then you need to find the volume of the cylinder. formula: pi * h * r^2. So it is 63.62. You now take this measure and subtract the volume of the three balls: 21.2in^3. To find the percentage, take 21.2/63.62. Then multiply by 100. The answer is 33.32, so your final answer is A.

Lilly has read seven-eighths of her book and is on page 147. How many pages does lilly have left to read?
lara [203]

Answer:

21

Step-by-step explanation:

Since Lilly has read 7/8 of her book (aka 147 pages), divide 147 by 7 and you get 21.

This means 1/8=21

Since she has read 7/8 of the book, and the full book is 8/8, 8/8-7/8= 1/8

Meaning she has 1/8 of the book left to read.

As said before, 1/8 =21

Thus, she has 21 pages left to read.

Please answer the question and please answer correctly... I really need help
Mekhanik [1.2K]

Answer:

The treatment decays by half each week.

Step-by-step explanation:

The decay function is given by:

y=a(1-r)^{t}

Here,

<em>y</em> = final value

<em>a</em> = initial value

<em>r</em> = decay rate

<em>t </em>= time

The decay function for one medications to treat dogs for fleas is:

F(x)=4\cdot (\frac{1}{2})^{w}

Here the decay rate is:

1-r=\frac{1}{2}\\\\r=1-\frac{1}{2}\\\\r=\frac{1}{2}

The treatment decays by half each week.
