A = Pert
Answers
Answer:
32 years
Step-by-step explanation:
fist find how much of 6750 is 6.25%
6750 * .0625 = 421.875
then use trial and error until u get the number u want
421.875 * 10 = 4218.75 + 6750 = 1096875 NO
421.875 * 20 = 84375 + 6750 = 151875 NO
421.875 * 30 = 12656.25 + 6750 = 19406.25 NO
421.875 * 31 = 13078.125 + 6750 = 19828.125 NO
421.875 * 32 = 13500 + 6750 = 20250 YES

"The difference between the circumference and diameter of a wheel is 18cm. Find the radius of the wheel. Use 3.14 for Pi. Round to the nearest tenth."
Answers
Answer:
[tex]4.2\ \text{cm}[/tex]
Step-by-step explanation:
d = Diameter of wheel
The difference between the circumference and diameter of a wheel is 18 cm.
[tex]2\pi r-d=18\\\Rightarrow \pi d-d=18\\\Rightarrow d(\pi-1)=18\\\Rightarrow d=\dfrac{18}{\pi -1}\\\Rightarrow d=\dfrac{18}{3.14-1}\\\Rightarrow d=8.41\ \text{cm}[/tex]
The diameter of the wheel is 8.41 cm so the radius will be [tex]\dfrac{8.41}{2}=4.205\approx 4.2\ \text{cm}[/tex].

Factoring Explanations Classwork
Directions:
For the following problems, you need to explain what method of factoring you will use and explain all the steps in English words. Do your best to format the math answers. *Some are much easier than others!*
Below are two examples:
Example #1: Factor 18x^2-200y^2 completely.
Answer: For this problem, we will use the difference of squares method.
First, we will factor out the greatest common factor which is 2.
2(9x^2-100y^2 )
Second, we must determine what a and b is.
a=√(〖9x〗^2 )=3x
b=√(〖100y〗^2 )=10y
Third, we put our answer in the form (a+b)(a-b), making sure to include the GCF 2.
Answer: 2(3x+10y)(3x-10y)
Example #2: Factor 2x^2-7x-15 completely.
Answer: For this problem, we will use the X method.
There is no GCF, so we will draw an x and put a*c on top (-30) and b on bottom (-7)
-10 and 3 multiply to get -30 and add to get -7.
Second, we split up the equation to now be this:
2x^2-10x+3x-15
Third, we group it together and factor out the GCF from each group.
(2x^2-10x)+(3x-15)
2x(x-5)+3(x-5)
Fourth and Last, we re-group it together to get our final answer.
Answer: (2x+3)(x-5)

A population of wolves in a county is represented by the
equation P(t) = 80(0.98)', where t is the number of years
since 1998. What is the percent decrease of wolves per year?
Answers
Answer:
P(t)=80(0.98)t P ( t ) = 80 ( 0.98 ) t , where t is the number of years since 1998 Step-by-step explanation:
P(t)=80(0.98)t P ( t ) = 80 ( 0.98 ) t , where t is the number of years since 1998
The percent decrease of wolves per year is 2%.
To understand more, check below explanation.
Percentage decrease :A population of wolves in a county is represented by the equation,
[tex]P(t)=80(0.98)^{t}[/tex]
where t is the number of years.
Let us consider that, 1998 is base year. so that, t = 0
[tex]P(0)=80[/tex]
Population of wolves in 1999, substitute t=1
[tex]P(1)=80*0.98=78.4[/tex]
the percent decrease of wolves per year is computed as;
[tex]=\frac{80-78.4}{80} *100\\\\=\frac{1.6}{100}*100\\ \\=0.02*100=2\%[/tex]
The percent decrease of wolves per year is 2%.

Answer:
$3
Step-by-step explanation:
Since he’s leaving a 20% tip, we need 20% of 15.
To solve, multiply 20/100 (20%) by 15:
20/100*15 = 300/100 = 3
He will leave a $3 tip.
Answer:
$3
Step-by-step explanation:
To solve this problem, first, one must convert the percent of the tip to decimal form. This can be done by dividing the percent by 100. Then one will multiply this value by the total bill.
20% * 15
= 0.2 * 15

Step-by-step explanation:
Suppose demand d for a company's product at cost x is predicted by the
function d(x)=0.36x + 810, and that the price p that the company can charge
for the product is given by p(x) = x+14. Find the company's revenue function.
Answers
Answer:
0.36x ² + 815.04x + 11,340
Step-by-step explanation:
Revenue = price × quantity
p(x) = x+14
d(x) = 0.36x + 810
Revenue = price × quantity
= (x + 14) * (0.36x + 810)
= 0.36x² + 810x + 5.04x + 11,340
= 0.36x ² + 815.04x + 11,340
Company's revenue = 0.36x ² + 815.04x + 11,340
