Why can’t one of the names be PNM, or MPN for the plane? But MNP can? What’s the difference, and why?
Savatey [412]

The names PNM and MPN are perfectly valid. The order of the letters doesn't matter. In fact, there are 6 ways to name this plane if we just use the 3 letters. If we include "plane Z", then there are 7 total ways to name the plane.

For some reason, your teacher wants P to be the third letter as s/he mentioned MNP and NMP. But again, the order doesn't matter.

URGENT HOMEWORK HELP!!
DedPeter [7]

Answer:

A

Step-by-step explanation:

The common difference is simply the constant we add/subtract each time. In this case, the common difference is 3/2 as can be seen from the recursive formula. In other words, each new n will be 3/2 larger than the previous.

The answer is A.

Help ASAP!!! Savings Account.Christine Chu borrowed $4500 from a bank at a simple interest rate of 2.5% for one year.
nydimaria [60]

Answer: $112.50 ; $4612.5

Step-by-step explanation:

a) Determine how much interest Christine paid at the end of 1 year.

This will be:

Simple interest = PRT/100

where

P = principal = $4500

R = rate = 2.5%

T = time = 1 year

Interest = (4500 × 2.5 × 1)/100

= 11250/100

= $112.50

b) Determine the total amount Christine will repay the bank at the end of 1 year.

Total amount = Principal + Interest

= $4500 + $112.50

= $4612.5

Factor each expression 30+10x-40y
Sergio039 [100]
Hello!

To factor you find the biggest number they can be divided by

The biggest number that all the number can be divided by is 10

You put that outside parenthesis

10()

Divide the expression by 10

3 + x - 4y

Put the two together

10(3 + x + 4y)

Hope this helps!

If the area of a circle is 20.4 units squared, what is the radius?
dmitriy555 [2]

Answer:

r = 2.55

Step-by-step explanation:

The formula for finding the radius of a circle using the area is r = √A/π

with the r being the radius. the A being the area, and the π being pi (we'll use 3.14).

So the equation should look like this:

r = √(20.4/3.14)

Find the quotient of 20.4/3.14 and round to the nearest tenth

r = √6.5

Find the square root and round to the nearest hundredth

r = 2.55
