Answers

Answer:

If youre trying to see which is cheaper, the local forklift would cost $1376.94 after tax. The other forklift would cost $1413.36.

Step-by-step explanation: Hope that helped

The cost after the sale will be $1376.94 and $1413.36.

What is the percentage?

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

You manage a warehouse and need to replace a forklift.

A local retailer sells the model you want for $1,299 plus a 6% sales tax. Then the cost after the sale will be

⇒ (1 + 0.06) x 1299

⇒ $1376.94

A store located just over the state line sells the same model for $1,359 plus a 4% sales tax. Then the cost after the sale will be

⇒ (1 + 0.04) x 1359

⇒ $1413.36

Answers

Answer: Option 'D' is correct.

Explanation:

We are required to find that length of sides which cannot be sides of triangle,

As we know that " Sum of two sides is always greater than the third side "

So, 21 m, 6 m, 10 m cannot be the length of any triangle as it does not satisfy the above mentioned postulate .

Answer:

C

Step-by-step explanation:

It is C because if you multiply each number on the left by 250 and then add 500, you will get the number on the right.

4 x 250 = 1000 + 500 = 1500

8 x 250 = 2000 + 500 = 2500

10 x 250 = 2500 + 500 = 3000

13 x 250 = 3250 + 500 = 3750
