To make everything easier, it's best to turn the mixed numbers into improper fractions.

24 * 8 = 192 + 3/8 = 195/8

4 * 8 = 32 + 7/8 = 39/8

The question asks how many 39/8-inch long pieces the worker cut from a 195/8-inch long board, meaning we have to divide.

195 / 39 = 5

The worker cut the board into 5 pieces.

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.

Find the value of k given that the line through (k,2) and (7,0) is perpendicular to the line y=x-28/5

Tanzania [10]

Y = x - 28/5. The slope here is 1. A perpendicular line will have a negative reciprocal slope. So our perpendicular line will have a slope of -1.

slope = (y2 - y1) / (x2 - x1)
(k,2)....x1 = k and y1 = 2
(7,0)...x2 = 7 and y2 = 0
sub
slope = (0 - 2) / (7 - k)
slope = -2 / ?......now if we want the slope to be -1..that means the number where the question mark is has to be 2....for that to happen, k has to be 5...because 7 - 5 = 2.

so ur answer is : k = 5
