Answers

Answer:

Option B. 1

Step-by-step explanation:

We have to find the value of P(3, 0)

We have to find the value of given permutation $^(3)P_(0)$

Since we know $^(a)P_(b)=(a!)/((a-b)!)$

Here a = 3

b = 0

$^(3)P_(0)=(3!)/((3-0)!)$

$=(3!)/(3!)=1$

Therefore, option B. 1 is the answer.

$_(3)P_(0) = (3!)/((3 - 0)!)$
$_(3)P_(0) = (3!)/(3!)$
$_(3)P_(0) = (3 * 2 * 1)/(3 * 2 * 1)$
$_(3)P_(0) = 1$

The answer is B.

You want to leave a nice tip on a $36 meal. So you decide to add 20% to the bill. How much is the total bill?

Answers

Answer:

43.20

Step-by-step explanation:

First find the tip

36 * 20 %

36 * .2

7.20

Then add the tip to the amount of the meal

36+7.20

43.20

You went to have a meal which costs $36, and maybe becoming very delighted with the taste and service of the food centre, you decided to add a tip.

$20\%$ of the total meal.

So, First we need to find the tip by multiplying the percentage with the cost of meal

Tip:

$20\% \: of \: 36$

$(20)/(100) * 36$

$(1)/(5) * 36$

$7.2$

Now, we have got the amount of money we decided to give as a tip. And, we are already having the cost of meal. So, total money paid:

$36 + 7.2$

$\boxed{ 43.2}$

This is our required answer.

How would you measure the volume of a cardboard shoebox

Answers

-- Measure the length of the box.
-- Measure the width of the box.
-- Measure the height of the box.
-- Make sure all 3 measurements are in the same units.

-- Multiply (length) x (width).

-- Take that answer and multiply it by (height).

-- You now have the volume of the box.

A circle with a CENTER 0 has a diameter of 16 cm. Points m and n are placed on the circle so that m/_MON =270. find the length of the intercepted arc of MN use 3.14 for pia. 21.4
b. 28.3
c. 32.5
d. 37.7

Answers

ok so remember
if x=degrees then the measure of the arc is
x/360=arclegnth/circumference
(if you understna that the angle's fraction out of 1 whole=arc's fraction out of circumference, you can use that info to make your own formula)
so
find circumference
c=pid
c=3.14*16
c=50.24

so
270/360=x/50.24
3/4=x/50.24
multiply both sides by (4*50.24)
150.72=4x
divide both sides by 4
39.68
round
37.7
