Naddik [55]

Answer:

Least to greatest: 2, 3, 1

Step-by-step explanation:

Square root of 8 over 2 is about 1.41 which makes it the least value

2 is obviously equal to 2 which puts it in the middle

Square root of 7 is about 2.64 which makes it the greatest value

The object below was made by placing a cone on top of a cylinder. The base of the cone is congruent to the base of the cylinder.

Ber [7]

Answer:

Part 1) The volume of the object is $32\pi\ cm^{3}$ or $100.48\ cm^{3}$

Part 2) see the procedure

Step-by-step explanation:

The picture of the question in the attached figure

Part 1) What is the volume, in cubic centimeters, of the object?

we know that

The volume of the object is equal to the volume of the cylinder plus the volume of the cone

Find the volume of the cone

The volume of the cone is equal to

$V=\frac{1}{3}\pi r^{2} h$

we have

$r=4/2=2\ cm$ -----> the radius is half the diameter

$h=3\ cm$

substitute the values

$V=\frac{1}{3}\pi (2^{2})(3)=4\pi\ cm^{3}$

Find the volume of the cylinder

The volume of the cylinder is equal to

$V=\pi r^{2} h$

we have

$r=4/2=2\ cm$ -----> the radius is half the diameter

$h=(10-3)=7\ cm$

substitute the values

$V=\pi (2^{2})(7)=28\pi\ cm^{3}$

Part 2) Then explain how you found the volume of the total shape

The volume of the total shape is equal to the volume of the cylinder plus the volume of the cone

$4\pi\ cm^{3}+28\pi\ cm^{3}=32\pi\ cm^{3}$ ------> exact value

Find the approximate value of the volume

assume

$\pi=3.14$

$32(3.14)=100.48\ cm^{3}$

If 3/4 of the library books are fiction and 5/7 are paperback what fraction of the books are fiction and paperback

Bess [88]

Answer:

15/38

Step-by-step explanation:

assuming the fraction of paperback in the fiction category is also 5/7, the fraction of the books which are fiction and paperback would just be the 2 fractions multiplied together.

(3,1) m=0 In standard form

diamong [38]

0x + y = 1 is the standard form of (3, 1) with m = 0

Solution:

We have been given a point and slope of an equation and have been asked to write it in the standard form.

The standard form of a line is in the form Ax + By = C where A is a positive integer, and B, and C are integers. The standard form of a line is just another way of writing the equation of a line.

The given point is (3,1) and the slope is 0

To write in standard form we will first write it in point slope form and then rearrange it into a standard from.

The point slope form of line is given as:

$y-y_{1}=m\left(x-x_{1}\right)$

Where "m" is the slope of the line

Here in this problem, $m = 0 , x_1 = 3 and y_1 = 1$

y - 1 = 0(x - 3)

y - 1 = 0

y = 1

since the above equation doesn’t have an ‘x’ term we convert into a standard form as follows:

0x + y = 1

This is the standard form for the given point and slope of a line.
