Luis has $12 and wants to buy 6.6 pounds of apples. Apples cost $1.80 per pound. Luis rounded each value and estimated that he does not have enough money to cover the cost of the apples before sales tax is applied. Which best explains how his estimate relates to the actual product?
Because each value rounds up, his estimate is higher than the actual product. He might have enough money to buy the apples.

Answer:

  A. Because each value rounds up, his estimate is higher than the actual product. He might have enough money to buy the apples.

Step-by-step explanation:

You want to know how Luis's estimate that $12 is not enough money to buy 6.6 pounds of apples at $1.80 per pound relates to the actual product. Luis rounded each value up.

Estimate

By rounding each value up before multiplying them, Luis arrived at a product that is higher than the actual product. This means ...

  A.  Because each value rounds up, his estimate is higher than the actual product. He might have enough money to buy the apples.

Figure ABCD is shown on the coordinate plane. Suppose a graphic designer wants to dilate the figure so that the resulting image has a smaller area than figure ABCD. Describe a way the designer can achieve this type of dilation.

Answers

Answer:

Step-by-step explanation:

If the dilated image is smaller than the original, then 0<k<1.

Meaning the scale factor is less than one, but greater than zero.

You would mulitply each coordinate by this scale factor - to obtain the coordinates of the dilated figure.

Let's choose   [tex]\frac{1}2}[/tex].

In the original figure Point A = (-4,3) dilating by [tex]\frac{1}{2}[/tex] results in A' being (-2, 1.5).  When you multiply each cooordinate (-4,3) by one half.

Applying the scale factor of one half to the other coordinates - yields these results.

Point B (4,3) becomes Point B' (2, 1.5)

Point C (-4,-4) becomes Point C' (-2,-2).

Point D (4, -4) becomes Point D' (2,-2)

A company has recently been hiring new employees. Today the company has 32% more employees than it did a year ago. If there are currently 29,700 employees, how many employees did the company have a year ago?

Answers

the company a  year ago had "x" employees, which oddly enough is the 100%.

now, today they have 32% more  than that, well, 100% + 32% = 132%, and we know that's 29,700 employees

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x & 100\\ 29700& 132 \end{array} \implies \cfrac{x}{29700}~~=~~\cfrac{100}{132} \\\\\\ \cfrac{ x }{ 29700 } ~~=~~ \cfrac{ 25 }{ 33 }\implies 33x=742500\implies x=\cfrac{742500}{33}\implies x=22500[/tex]
