Mathematics
1 answer:
Evgen [1.6K]3 years ago

Answer:

AB = 16

Step-by-step explanation:

The perimeter is the sum of all 5 sides of the pentagon

Sum the 5 sides, equate to 69 and solve for x

12 + 3x + 10 + x + 3 + 2x + 2 = 69

6x + 27 = 69 ( subtract 27 from both sides )

6x = 42 ( divide both sides by 6 )

x = 7

AB = 2x + 2 = (2 × 7) + 2 = 14 + 2 = 16

Aaron the car wash owner had 228 quarters and 120 dimes.

<h3>Equation</h3>

An equation is an expression used to show the relationship between two or more variables and numbers.

Let x represent the number of quarters and y represent the number of dimes. Hence:

x = 90% of y + y

x = (0.9y) + y

x - 1.9y = 0   (1)

Also:

0.25x + 0.1y = 69   (2)

From both equations:

x = 228, y = 120

Aaron the car wash owner had 228 quarters and 120 dimes.

Answer:

  • Keep plugging in the points and see the ones that work, for example, (-1,7)
  • y=5x+12\\(7)=5(-1)+12\\7=7 true, so select it
  • Keep doing that for the rest of them , some like (3,15) won't work so you just have to keep testing each point.

Ryobi Limited sold a set of saws to Ace Hardware. The list price was $3,800. Ryobi offered a chain discount of 8/3/1. What's the
laila [671]

Answer:  Option 'B' is correct.

Our net price will be $3357.21.

Explanation:

Since we have given that

The list price of set of saws = $3800

There are 3 successive discounts :

8%,3%,1%

So, if we apply first for 8% discount our new price becomes,

3800\times \frac{100-8}{100}=3800\times 0.92=\$3496

Now, if we apply 3% on our deducted price , our new price becomes ,

3496\times \frac{100-3}{100}=3496\times 0.97=\$3391.12

Now, we'll apply for 1% on our new deducted price , our net price becomes,

3391.12\times \frac{100-1}{100}=3391.12\times 0.99=\$3357.21

Hence, our net price will be $3357.21.

Therefore, Option 'B' is correct.
