Answer:

$1000

Step-by-step explanation:

We are given that,

Price of concrete = 0.02 dollars per pound

Tax rate on concrete = 0.03 per pound

Thus, the total cost of the concrete = 0.02 + 0.03 = 0.05 dollars per pound

Since, we know,

1 pound = 0.0005 tons

As, Cost of 1 pound = $0.05

i.e. Cost of 0.0005 tons = $0.05

Then, cost of 1 ton = \frac{0.5}{0.0005} = $1000.

Hence, the cost Tommy needs to pay is $1000.

There are 3 feet in 1 yard. This is equivalent to 12 feet in 4 yards. Which proportion can be used to represent this?
Troyanec [42]

Proportion which can be used to represent equivalency of 3 feet in 1 yard and 12 feet in 4 yard is 3 : 1 : : 12 : 4

<h3><u>Solution:</u></h3>

Given that

There are 3 feet in one yard  

And there are 12 feet in 4 yard  

Number of feet in one yard = 3 that is feet  : yard = 3 : 1  

Number of feet in 4 yards = 12 that is feet : yard = 12 : 4  

And 3 feet in 1 yard is equivalent to 12 feet in 4 yards means

\frac{3}{1}=\frac{12}{4}

That is 3 : 1 : : 12 : 4

A proportion is statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a : b = c : d

Hence proportion which can be used to represent equivalency of 3 feet in 1 yard and 12 feet in 4 yard is 3 : 1 :: 12 : 4
