A customer uses a 50% coupon good toward any household cleaning product. if the customer's purchase consists of the items below,

Vlad [161]

Here is the answer to the given problem above. Given the list of items above, since the 50% coupon only applies to any household cleaning product, this coupon will only apply to the carpet shampoo which has a price of $6.90. So 50% of this would be $3.45. So the rest of the prices of the other items would remain the same. So to sum it all, the total bill would be $8.50, without the sales tax. So we add the sales tax for this and the total would be this: $9.0525. The tax for this of 6.5% tax is 0.5525. Hope this answers your question. Have a great day!

What is the volume of this right cone?

defon

Question:

What is the volume of this right cone?

40π cm³

300π cm³

400π cm³

480π cm³

The image of the cone is attached below:

Answer:

Option c: 400π cm³

Explanation:

It is given that a right cone with radius = 10 cm , height = 12 cm and lateral height 15.6 cm

To determine the volume of the right cone, let us substitute these values in the formula,

$V=\frac{1}{3} \pi r^{2} h$

Thus, we get,

$V=\frac{1}{3} \pi (10)^{2}(12)$

Multiplying the terms,

$V=\frac{1}{3} \pi (1200)$

Dividing by 3, we get,

$V=400 \pi$

Thus, the volume of the cone is 400π cm³

Hence, Option c is the correct answer.

Answer:

0.1289

Step-by-step explanation:

Given that two companies have sent representatives to an industry conference.

The first company sent 12 representatives and the second company sent 20 representatives

Selecting any 22 out of these 32 can be done in $32C22 ==\frac{32!}{(22!(32−22)!)} \\= 64512240$

Favourable outcomes = No of ways of selecting 10 from I and 12 from II

= $12C10(20C12) =66(125970) \\=8314020$

Probability required = $\frac{8314020}{64512240} \\=0.1289$
