Jackie wants to keep her total work time under 20 hours, so we can set up a rough inequality right away:

(work time in hours) < 20

Now, it's going to take here 1/2 = 0.5 hours to finish each necklace, an 1 hour to finish each bracelet, so if she's making x necklaces, it'll take her 0.5x hours to make all of them, and if she's making y bracelets, it'll take her 1y = y hours to finish those. Putting the two together, it'll take her 0.5x + y hours altogether to make the necklaces and bracelets. Putting that together with our first inequality, we get the final inequality

0.5x + y < 20

Find the ratio of the volume of one sphere to the volume of the right cylinder

yarga [219]

Answer:

Step-by-step explanation:

Let $r$ be the radius of one sphere.

Volume of sphere is $V=\frac{4}{3}\pi r^3$

Since radius is r, the height of the cylinder will be $4r$

Also, the cylinder has the same radius as the sphere: $r$

Volume of Cylinder is $V=\pi r^2 h$

Plugging in the values we get: $V=\pi (r)^{2}(4r)=4\pi r^3$

Ratio of volume of 1 sphere to volume of cylinder is:

$\frac{\frac{4}{3}\pi r^3}{4\pi r^3}=\frac{\frac{4}{3}}{4}=\frac{4}{3}*\frac{1}{4}=\frac{1}{3}$

The ratio is 1:3

Answer choice B is right.

Lou has a solid clay brick in the shape of a rectangular prism with a length of 8 inches, a width of 3.5 inches, and a height of

Rzqust [24]

The weight of solid clay brick is 66.465 ounces, if solid brick with a length of 8 inches, a width of 3.5 inches, and a height of 2.25 inches and the clay weighs 1.055 ounces per cubic inch.

Step-by-step explanation:

The given is,

A solid clay brick in the shape of a rectangular prism.

A length of 8 inches, a width of 3.5 inches, and a height of 2.25 inches.

The clay weighs 1.055 ounces per cubic

Step:1

Formula for volume of rectangular prism,

$Volume, V= whl$ ...................(1)

Where, w - Width of the rectangular prism

h - Height of rectangular prism

l - Length of rectangular prism

From the given,

w = 3.5 inches

h = 2.25 inches

l = 8 inches

Equation (1) becomes,

$= (3.5)(2.25)(8)$

$= (7.875)(8)$

$= 63$

Volume, V = 63 cubic inches

Step:2

Weight of brick = Volume of brick × Weight per cubic inch

$= (63) (1.055)$

= 66.465 ounces

Weight of brick = 66.465 ounces

Result:

The weight of solid clay brick is 66.465 ounces, if solid brick with a length of 8 inches, a width of 3.5 inches, and a height of 2.25 inches and the clay weighs 1.055 ounces per cubic inch.
