C = circumference.
D = diameter

C = $\pi$ X D
C = 8[tex] \pi [tex]

To the nearest tenth, what is the distance between the points (1, –2, 5) and (0, 7, –4)?

Eduardwww [97]

Answer:

The distance is $12.8\ units$

Step-by-step explanation:

we know that

The formula to calculate the distance between two points is equal to

$d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2}+(z2-z1)^{2}}$

we have

$A(1,-2,5)\\B(0,7,-4)$

substitute the values

$d=\sqrt{(0-1)^{2}+(7+2)^{2}+(-4-5)^{2}}$

$d=\sqrt{(-1)^{2}+(9)^{2}+(-9)^{2}}$

$d=\sqrt{1+81+81}$

$d=\sqrt{163}\ units$

$d=12.8\ units$

The amount a tree grows in one month is directly proportional to the amount of water it is given. When a tree is giving 21 gallo

mr_godi [17]

Answer:

k = 0.381cm/gallon

Step-by-step explanation:

Let the amount a tree grows in one month be x

Let amount of water it is given be y

If the amount a tree grows in one month is directly proportional to the amount of water it is given, then;

x ∝ y

x = ky

k is the constant of proportionality

k = x/y

Given

x = 8cm

y = 21 gallons

k = 8/21

k = 0.381cm/gallon

Answer:

3. B. 128

4. B. 50.24

Step-by-step explanation:

3. The Books

The numbers of the problem make it quite easy.

We can easily figure out how many books will be stacked in each dimension of the trunk.

Length:

Books: 10 inches

Trunk: 40 iinches.

How may books can you fit lengthwise in the trunk? 40 / 10 = 4

We then to the same for the width:

Books: 6 inches

Trunk: 24 inches

How many books can you stack wide-wise in the trunk? 26/4 = 4

And then the height:

Books: 2.5 inches

Trunk: 20 inches

How many books stacked in height? 20 / 2.5 = 8

So, we can saw the trunk is 4 books long, by 4 books wide by 8 books thick... so, the number of books you can fit in that trunk is:

B = 4 * 4 * 8 = 128

4. Tomato juice

First, we have to find the volume of that big can...

Since it's a cylinder, its volume is calculated by:

V = π * r² * h and we have everything we need:

V = 3.14 * 4² * 12 = 192 * 3.14 = 602.88 cu in

We know a cup of tomato juice takes 12 cu inches...

So, how many cups of juice fit in that can?

C = 602.88 cu in / 12 cu in/cup = 50.24 cups
