Marie is purchasing a $108,000 home with a 30 year ortgage at 5.25%. What is her monthly principal and interest payment

schepotkina [342]

Answer:

Monthly interest rate is r=0,004375

Monthly principal c=590,625

Step-by-step explanation:

Monthly interest payment rate :

$r=\frac{5.25}{12}:100=0,0004375$

Now, we need to find monthly principal payment : $c=\frac{rP}{1-(1+r)^{-N}}$

Use this rule : $N=30*12=360$

P=108000

r=0,004375

$c=\frac{0.004375*108000}{1-(1+0.004375)^{-360}} =\frac{472.5}{0.8}=590,625$

If the dimensions of the following cylinder are quadrupled, what will be the volume of the new similar cylinder?

Alik [6]

Answer: First option is correct.

Explanation:

Since we have given that

Radius = 11 inches

Height = 14 inches

Now, according to question, we have mentioned that all the dimensions of the cylinder is to be quadrupled i.e. four times.

Then,

Radius is given by

$4\times 11=44 inches$

Height is given by

$14\times 4=56\ inches$

As we know the formula for " Volume of cylinder ":

$V=\pi r^2h\\\\V=3.14\times 44\times 44\times 56=340426.24\ in^3$

Hence, our volume of new similar cylinder is 340426.24 cubic in.

Therefore, First option is correct.

Which equation could be used to solve this problem? The sum of two consecutive odd integers is 24. Let n represent the first int

USPshnik [31]

If n is the first integer, then n+2 is the second one. The equation for the sum can be written as
n + (n+2) = 24 . . . . . . this equation can be used to solve the problem

2n = 22 . . . . . . . . . . . simplify, subtract 2
n = 11

The integers are 11 and 13.

_____
I like to solve problems like this by looking at the average of the integers. Here, it is 24/2 = 12. The consecutive odd integers whose average is 12 are 11 and 13.

What is the difference in medians of the two box plots? de27a97d-2652-45fd-92f8-2f37a2ac7b09?W=400&h=400

Veronika [31]

*see attachment for the diagram of the two box plots referred to here.

Answer:

2 inches

Step-by-step explanation:

The median of a box plot is the data value that lies exactly where the vertical line divides the box into two.

Therefore:

Median for Class 1 = 17 inches

Median for class 2 = 15 inches

The difference in the medians of both box plots = 17 - 15 = 2 inches
