"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].

Rope packaged in 80-foot lengths

of rope are needed for the job, how
many packages of rope are needed?
(A) 4
(B) 5
(C) 6
(D) 7
(E) 28
Answers
Answer:
it would be 5
Step-by-step explanation:
any of the answer could have really worked (not 4 since that gives you less then what is needed) but in the end it would have been 5 because 5 leaves you with only 5.33 feet of rope left
80* any one of the four numbers (ex: 5) = your answer that you got (ex: 400)
then you divide that number by 28 (ex: 33.33) and if you want to go the extra mile then do the number that you got by dividing 28 minis the number of rope pieces needed
the whole thing >
80* 5 = 400
400/28 = 33.33
33.33- 28 = 5.33

Answers
Explanation:
X^3 stays the same because there are no other cubed numbers in the problem
Next you combine the x^2s
The x^2s are +3x^2 and +2x^2
Since they are both positive, you add them: 3x^2 + 2x^2 = 5x^2
Next you do the x values
-x and +6x, also known as 6x - x = 5x
Lastly, you just add in the -2 and get:

A cylinder has a volume of 36 cubic inches. What is the volume of a cone if it has the same radius and height as the cylinder?
Answers
Answer:
12 cubic inches
Step-by-step explanation:
volume of a cylinder= pi*r2*height
but we are given 36 as cylinder volume.
Therefore , 36 = pi*r2* height
r2*height = 36/pi, let call this equation 1
volume of a cone = pi*r2*height/3;
but from equation 1, r2*height =36/pi, substituting this value in volume of cone.
volume of cone= pi*(36/pi)/3 = 12 cubic inches

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

Answer:

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
= 3
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%.
