There's a lot of ways to solve this and get the same answer. No matter what, you definitely need to convert feet an yards.

Starting with what you know, one balloon needs 2.5 feet of ribbon.

You also know that three feet make a yard.

Your final answer asks for yards of ribbon for 18 balloons.

So, some ways to solve would be:

1. Multiply 2.5 by 18. That would end up being 45 feet for 18 balloons. You want yards. Yards are bigger than feet, and so you would want to divide. 45 divided by 3 is 15 yards for 18 balloons.

You could also do:

2. Convert first. 2.5 feet would be not a whole number of yards, but you would do 2.5 divided by 3. It would be a decimal ( you could find out in a calculator ) then, multiply by 18 for the number of balloons and you get 15 yards for 18 balloons.

The answer would ultimately be 15.

What is the area of the rhombus in simplest radical form? The figure is not drawn to scale.
Tanya [424]

The area of the Rhombus is 162√3 sq.unit , Option A is the correct answer.

<h3>What is a Rhombus ?</h3>

A rhombus is a polygon , which has four equal sides , its diagonal bisect each other at 90 degree.

Let x be the half of the other diagonal.

tan 60 = x / 9

x = 9 tan 60

x = 9√3

Area of the Rhombus = (d1 * d2 /2 )

d1 and d2 are the length of the diagonal.

Area of the Rhombus = (9*2)(2 *9√3)/2

Area of the Rhombus =162√3 sq.unit

An experience bricklayer can construct a small wall in 3 hours. An apprentice can complete the job in 5 hours. Find how long it
Over [174]

Answer:

Step-by-step explanation:

If the bricklayer can construct the wall in its entirety in 3 hours, then he can get 1/3 of the job done in an hour.

If the apprentice can get the whole job done in 5 hours, then he can get 1/5 of the job done in an hour. If they both work together on said job, the equation is

\frac{1}{3}+\frac{1}{5}=\frac{1}{x} and now we solve for x. Multiply everything by the LCM to get rid of the fractions. That would be 15x:

15x(\frac{1}{3}+\frac{1}{5}=\frac{1}{x}) and doing that gives us

5x + 3x = 15 and

8x = 15 so

x = 1.875 hours which is 1 7/8 hours which is also 1 hour and 52 1/2 minutes.

What are scale drawings? can you give an example?
Alecsey [184]
Scale Drawings are drawings that are used to show the true size of something.
Scale drawings are most commonly used in maps, or in large scale drawings. These show the scale of something. It may show that 1cm is equivalent to 1km, which would allow someone to measure the map to see how far the distance it. It also allows a map to be made smaller, and less detailed- making it often easier to read.
Hope this helps :)
