If a solid has a density of 4.0 g/cm^3, what volume provides 24 g of that<br> solid? Show work.
Troyanec [42]
<h3>Answer: 6 cm^3</h3>

This is the same as saying 6 cubic cm

====================================================

Work Shown:

d = density = 4 g/cm^3

m = mass = 24 g

v = volume = unknown

--------------

d = m/v

4 = 24/v

4v = 24 .... multiply both sides by v

v = 24/4 .... divide both sides by 4

v = 6 cm^3

A rectangular yoga mat has a perimeter of 179 inches. The width of the mat is eight less than half the length. Find the width, i
lianna [129]

Answer:

The width is 24.5in

Step-by-step explanation:

The perimeter of the rectangular yoga mat can be found using the formula;

P=2l+2w.

\Rightarrow 179=2l+2w...(1).

It was given that the width of the mat is eight less than half the length.

w=\frac{1}{2}l-8...(2)

We put equation (2) into equation (1) to get;

179=2l+2(\frac{1}{2}l-8).

\Rightarrow 179=2l+l-16.

\Rightarrow 179+16=2l+l.

\Rightarrow 3l=195

Divide both sides by 3;

l=65

We put l=65 into equation 2 to get;

w=\frac{1}{2}\times65-8

w=32.5-8

w=24.5in

Matthew had exactly 20 pennies in his pocket. Five were Canadian pennies and the rest were U.S. Pennies. If he took 1 penny out
Lemur [1.5K]

Answer:

1/4

This is also same as 0.25

Step-by-step explanation:

Probability is the ratio of the number of possible outcomes to the total outcome.

Given that there are 20 pennies and 5 were Canadian pennies, this means that the number of American  pennies

= 20 - 5

= 15

If one penny is taken out of his pocket at random, the probability or odds that it would be a Canadian penny P(C)

= 5/20

= 1/4 (To the lowest term)

= 0.25 ( in decimal)
