Using proportions, it is found that the actual cost of each pineapple is of $2.12

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

A proportion is a fraction of a total amount.

In this problem, considering that the waste factor is of 15%, the<em> </em>total price<em> </em>should be of:

P = 0.85 x $14.95 = $12.7075.

For a case of 6 pineapples, hence the price of each is given by:

Pp = $12.7075/6 = $2.12.

The actual cost of each pineapple with a waste factor of 15% is $12.71

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

The cost of one case of fresh pineapples is $14.95 and the calculated waste factor is 15 percent. Hence:

Actual cost = 14.95 - 15% of 14.95 = $12.71

The actual cost of each pineapple with a waste factor of 15% is $12.71

PLS QUICK I ONLY HAVE 2 HOURS

UNO [17]

Answer:

Step-by-step explanation:

As you can observe from the pattern, the numerator gets multiplied by 4 every increase in the sequence.

So , clearly, the 5th term will be = $\frac{64*4}{5} =\frac{256}{5}$

and the 6th term will be = $\frac{256*4}{5} =\frac{1024}{5}$

Therefore , D will be the answer.

A copy machine makes 28 copies per minute. How many copies does it make in 3 minutes and 45 seconds?

lina2011 [118]

<u>Convert minutes and seconds to minutes:</u>
$\text{3 mins 45 seconds} \longrightarrow 3 \dfrac{3}{4} \text{mins}$

<u>FInd 3 3/4 mins:</u>
$\text{1 min} \longrightarrow 28 \text{ copies}$

$3 \dfrac{3}{4} \text{ min} \longrightarrow 28 \times 3\dfrac{3}{4} \text{ copies}$

$3 \dfrac{3}{4} \text{ min} \longrightarrow 28 \times \dfrac{15}{4} \text{ copies}$

$3 \dfrac{3}{4} \text{ min} \longrightarrow 105 \text{ copies}$

Answer: It can make 105 copies.

An artist builds a sculpture out of metal and wood that weighs 14.9 kilograms. 3/4 of this weight is metal and the rest is wood.

Troyanec [42]

Answer:

Given is a sculpture that is built up of metal and wood, and the weight of this sculpture is 14.9 kilograms.

It says that three-fourth of the total weight is metal and says to find the weight of wooden part.

We can find the weight of metal part and then subtract it from the total weight to calculate the answer.

Total weight = 14.9 kilograms.

Metal part = three-fourth of total weight =

Wooden part = 14.9 - 11.175 = 3.725 kilograms.

Hence, the wooden part is 3.725 kilograms.
