Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as Hernando and Rachel's solution are not provided. So, I will just solve the question directly.
Given
[tex]2mp-6p+27-9m[/tex]
Required
Factor
[tex]2mp-6p+27-9m[/tex]
Group into 2
[tex]2mp-6p+27-9m = [2mp-6p]+[27-9m][/tex]
Factor each group
[tex]2mp-6p+27-9m = 2p[m-3]+9[3-m][/tex]
Rewrite 3 - m as -(m-3)
So, we have:
[tex]2mp-6p+27-9m = 2p[m-3]-9[m-3][/tex]
Factor out m - 3
[tex]2mp-6p+27-9m = [2p-9][m-3][/tex]

A new business borrows $320,000 at a yearly simple interest rate of 7%. The total
amount the company repays for the loan and interest is $678,400. How long did it
take to pay off the loan?
Interest = (principal)(rate in decimal)(time in years)
1 = (p) (0) (t)
1. Read the word problem and circle and label the
interest, principal, rate, and time in years given in
the problem.
2. Underline the question(s)
3. Make any conversions needed for example:
a. Percent into decimals
b.
Months into years
4. Write down the simple interest formula
5 Plug in the known variables into the interest formula
6. Solve for the unknown
7. Answer the questions using complete sentences
and question stem
Answer:
16 years
Step-by-step explanation:
Annual interest payment is 7% * 320k = 22,400
Total interest is 678400-320000=358400
358400/22400=16

coterminal angles
HELP what is the coterminal angle for -230° in the range of (0,360°)
Answer:
The coterminal angle of -230º is 130º.
Step-by-step explanation:
Coterminal angles are those whose sides start and end at the same point, therefore sharing a common side. To obtain the coterminal angle of a negative angle, 360º must be added to the value of said negative angle. Therefore, the coterminal angle of -230º arises from the following calculation:
-230 + 360 = X
130 = X
Therefore, the coterminal angle of -230º is 130º.
Anna shops in an international store. A t-shirt with a tag price P420 is marked “save 20%.” How much will Anna have to pay for the t-shirt if she were to buy it?
Given:
Marked price of t-shirt = 420
Discount rate = 20%
To find:
The price of the t-shirt after discount.
Solution:
The price of the t-shirt after discount is 20% of less than the marked price of it.
Price of the t-shirt after discount = Marked price - 20% of Marked price
= [tex]420-\dfrac{20}{100}\times 420[/tex]
= [tex]420-84[/tex]
= [tex]336[/tex]
Therefore, the price of the t-shirt after discount is P336.

Answer:
[tex]\frac{1}{736}[/tex]
Step-by-step explanation:
This is a simple exponential function (or arithmetic sequence) of
f(x) = 23(2)^x
Since this is fraction 5, x = 5
f(5) = 23(2)^5
f(5) = 23(32)
f(5) = 736
The answer is [tex]\frac{1}{736}[/tex]
find the value of x in this image
Answer:
x = 39
Step-by-step explanation:
Its an isosceles triangle, so,
angle A = angle C = 2x
Sum of angles in a triangle = 180, which is why when you add x - 15 , 2x and 2x its equal to 180.
Now you have a linear equation. Solve it to find the value of x.
A shirt originally cost $41.10, but it is on sale for $36.99. What is the percentage decrease of the price of the shirt? If necessary, round to the nearest percent. A. 10% B. 90% C. 11% D. 8%
Answer:
10%
Step-by-step explanation:
The first step is to calculate the decrease
Original price= $41.10
New price= $36.99
= 41.10-36.99
= 4.11
4.11/41.10 × 100
= 0.1×100
= 10%
Hence the percentage decrease is 10%

The bases in a softball diamond are located at the corners of a 3600 ft^2 square. How far is a throw from second base to home plate
Answer:
84.85 ft
Step-by-step explanation:
Given that the sides are 3600 feets
Hence, side 1 = 3600 ; side = 3600 (since it is a square)
The distance, d from second base to Home plate is the length of the diagonal, which can be obtained using Pythagoras :
d² = s1² + s2²
s1², s2² = 3600
Hence,
d = sqrt(3600 +. 3600)
d = sqrt(7200)
d = 84.85 ft
