The sum of three consecutive integers is greater than 66. What is the smallest possible product of the largest and smallest of t
AysviL [449]

Answer:

528

Step-by-step explanation:

So naturally at first sight for this question we would think -->

Oh 3 consecutive integers = 66 --> 66/3 = 22 (n-1), (n+1) so --> 21, 22, and 23.

But no. At second look it is the sum of 3 consecutive integers is greater than 66. So we find the next possible pair since it says smallest possible product.

We get the set (22, 23, 24). => Multiply the least and greatest integers together respectively 22 and 24 which amounts to => 528

And thus, we have out answer of 528

Hope this helps!

You want to buy an item that costs $100. Which of these is the most cost-effective choice for buying the item?. a. using a paid
Paraphin [41]

<u>Answer</u>

c. buying it at a 10 percent discount without sales tax.


<u>Explanation</u>

We are going to compare the 3 choices and then determine the most cost effective.

<em>a. using a paid membership card to buy it at a 10 percent discount.</em>

10% of $100 = 10/100×100 = $10

cost = $100 - $10 = $90

On top of this $90 there is the charges of the membership card.

<em> b. buying it online at a 10 percent discount with a $5 shipping charge.</em>

100%-10% = 90%

90% of 100 = $90

Cost: $90 + $5 = $95

<em>c. buying it at a 10 percent discount without sales tax.</em>

100% - 10% = 90%

90/100 × 100 = $90. This is the must cost effective method since there is no other cost involved.

Reuben bought a desktop computer and a laptop computer. Before finance charges, the laptop cost $150 more than the desktop. He p
cupoosta [38]
Same case as Pablo's, more or less.

a = price for the desktop

b = price for the laptop

we know the laptop is 150 bucks more than the desktop,  b = a + 150.

how much is 7% of a?  (7/100) * a, 0.07a.

how much is 9.5% of b?  (9.5/100) * b, 0.095b.

total interests for the financing add up to 303, 0.07a + 0.095b = 303.

\bf \begin{cases}&#10;\boxed{b}=a+150\\&#10;0.07a+0.095b=303\\&#10;----------\\&#10;0.07a+0.095\left(\boxed{a+150}  \right)=303&#10;\end{cases}&#10;\\\\\\&#10;0.07a+0.095a+14.25=303\implies 0.165a=288.75&#10;\\\\\\&#10;a=\cfrac{288.75}{0.165}\implies a=1750

how much was it for the laptop?  well b = a + 150.

When a transversal is perpendicular to two parallel lines, all the angles formed measure 90°. Explain why.
kotykmax [81]
When two parallel lines are cut by a transversal, due to the natures of the different relationships among the angles, all of them will be either equal to the measure of the first angle or equal to that angle subtracted from 180.  If the transversal is perpendicular to the parallel lines, forms a right angle, then both the angle given and the angle subtracted from 180 will be 90.  This means all of the angles will be 90.
