zachary has coins of the coins 3/6 are nickles, 2/6 dimes, rest are quarters. What is the ratio of zacharies nickles, to dimes t

lesya692 [45]

Answer:

The ratio of zacharies nickels to dimes to quarters is <u>3 : 2 : 1</u>.

Step-by-step explanation:

Given:

Zachary has coins of the coins 3/6 are nickels, 2/6 dimes, rest are quarters.

Now, to get the ratio of zacharies nickels, to dimes to quarters.

So, as given dimes and nickels we find the quarters to get the ratio:

$\frac{3}{6} -\frac{2}{6}=\frac{3-2}{6} =\frac{1}{6}$ .

Thus, the quarters are 1/6.

Now, getting the ratio of the coins:

Nickels = 3/6 × 6 = 3

Dimes = 2/6 × 6 = 2

Quarters = 1/6 × 6 = 1

<em>Nickels : Dimes : Quarters = 3 : 2 : 1.</em>

Therefore, the ratio of zacharies nickels to dimes to quarters is 3 : 2 : 1.

Alicia wants to cover a footrest in the shape of a rectangular prism with cotton fabric. The footrest is 14 inches by 11 inches

kati45 [8]

Answer:

Since the footrest measures 1.54 square yards, Alice will not be able to cover it completely.

Step-by-step explanation:

Since Alicia wants to cover a footrest in the shape of a rectangular prism with cotton fabric, and the footrest is 14 inches by 11 inches by 13 inches while she has 1 square yard of fabric, to determine if she can she completly cover the footrest the following calculation must be performed:

1 square yard = 1296 square inches

14 x 11 x 13 = X

154 x 13 = X

2.002 = X

2.002 / 1.296 = 1.54

Thus, since the footrest measures 1.54 square yards, Alice will not be able to cover it completely.

In-s [12.5K]

The 3D prism that produced the cross-section of a triangle is a triangular prism.

<h3>How to describe the 3D prism?</h3>

From the given figure, we can see that the cross-section is a triangle

One of the faces of a triangular prism is a triangle.

This means that when the triangular prism is cut vertically, a triangle face is created

Hence, the 3D prism that produced the cross-section of a triangle is a triangular prism.
