iven a role of nickels. The diameter of one nickel is 0.835 inches, and the thickness is 0.077 inches. Find the surface area of a roll of $2 in nickels. Round to the nearest tenth.
*use π on your sci calculator.
Surface Area =
Answer:
The answer is 0.8 in^2
Step-by-step explanation:
Data
diameter = 0.835 in
thickness = 0.077in
Roll of $ 2.00
Procedure
1.- Find the total number of nickels
# of nickels = 2/ 0.05
# of nickels = 40
2.- Calculate the Circumference
C = 2*pi*r
r = 0.077/2
r = 0.0385
C = 2*3.14*0.0385
C = 0.242 in
3.- Calculate the area of the thickness
Area = 0.242* 0.077*40
Area = 0.745 in^2
4.- Calculate the area of the base and the top
Area = 2*pi*r^2
Area = 2*3.14*(0.0382)^2
Area = 0.0093 in^2
5.- Calculate the total area of the roll
Total area = Area of the thickness + Area of the base and top
Total area = 0.745 + 0.0093
Total area = 0.7543 in^2 This is the result
Rounding to the nearest tenth = 0.8 in^2

Tanisha and Bess are sisters. Tanisha is half as old as Bess. Bess is 6 years older than Tanisha.
How old is each sister?
A. Tanisha is 3, and Bess is 6.
B. Tanisha is 3, and Bess is 9.
c. Tanisha is 6, and Bess is 9.
D. Tanisha is 6, and Bess is 12.
Answer: a
Step-by-step explanation: because bess it says she has 6 and is 3 it says have of 6 is 3 so it is 3
The age of Tanisha is 6 years and the age of Bess is 12 years. Therefore, option D is the correct answer.
We need to find the age of Tanisha and Bess.
What is an equation?A statement that the values of two mathematical expressions are equal (indicated by the sign =).
Let the age of Tanisha be x.
Bess is 6 years older than Tanisha.
Now, Bess=x+6
Tanisha is half as old as Bess.
Now, Tanisha=1/2×Bess
⇒x=1/2×(x+6)
⇒x=6
So, Tanisha's age=6 years and Bess's age=12 years.

*7. Mrs. Martin rents a car for $36 plus $0.15 per mile. His budget is $60.
How many miles can she drive? *
A. 160 miles
B. 150 miles
C. 140 miles
D. 130 miles
Answer:
The answer is A
Step-by-step explanation:
60-36= 24/0.15=160
9514 1404 393
Answer:
(a) 160 miles
Step-by-step explanation:
Let m represent the number of miles Mrs Martin drives. Her rental cost is ...
c = 36 +0.15m
She wants to find m when that is equal to $60.
60 = 36 +0.15m
24 = 0.15m . . . . . . . subtract 36
24/0.15 = m = 160 . . . . divide by the coefficient of m
Mrs. Martin can afford to drive up to 160 miles.

what does this mean 4x + 6y=9
12x + 18y=27
Answer: Infinite solutions
Step-by-step explanation:
Solve4x+6y=9for x:
4x+6y=9
4x+6y+−6y=9+−6y(Add -6y to both sides)
4x=−6y+9
4x /4 = −6y+9 /4
(Divide both sides by 4)
x= −3 /2 y+ 9 /4
Substitute
−3 /2 y+ 9 /4
for x in 12x+18y=27:
12x+18y=27
12( −3 /2 y+ 9 /4 )+18y=27
27=27(Simplify both sides of the equation)
27+−27=27+−27(Add -27 to both sides)

Nicholas has a pepper shaker in the shape of a cylinder. It has a radius of 9 mm and height of 32 mm. How much pepper will for in the shaker
By using the fοrmula fοr the vοlume οf a cylinder, the pepper shaker can hοld apprοximately 8,159.15 cubic millimetres οf pepper.
What is the vοlume οf a cylinder ?The fοrmula tο calculate the vοlume οf a cylinder:
V = πr²h
where:
V = vοlume
r = radius
h = height
Tο calculate the vοlume οf the pepper shaker, we need tο use the fοrmula fοr the vοlume οf a cylinder.
In this case, we have:
r = 9 mm
h = 32 mm
Sο the fοrmula becοmes:
V = π(9 mm)²(32 mm)
V = π(81 mm²)(32 mm)
V = 81π(32) mm³
V ≈ 8,159.15 mm³
Therefοre, the pepper shaker can hοld apprοximately 8,159.15 cubic millimeters (οr milliliters) οf pepper.

Savannah deposited $500 into an account that pays simple interest at a rate of 5% per year. How much interest will she be paid in the first 7 years?
Answer:$266
Step-by-step explanation:
Cameron :
r = 4 3/8% = 0.04375
P = 7400
For account compounded continuously :
A = Pe^it
i = interest ; t number of years ;
A = 7400 * e^0.04375*7
A = 7400 * e^0.30625
A = 10051.581
Savanna:
r = 4 3/4% = 0.0475
P = 7400
A = P(1 + r/n)^nt
n = number of compounding times per period
A = final amount ; P = initial investment
Compounded daily :
A = 7400(1 + 0.0475/365)^365*7
A = 7400(1 + 0.0001301)^2555
A = 7400(1.0001301)^2555
A = 7400 * 1.3942879
A = 10317.731
Difference :
$(10317.731 - 10051.581)
= $266.15
= $266 (nearest dollar)
