Given a roll 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.
PLS RESPOND ASAP I NEED THE ANSWER PLSSSS
Answers
Answer:
124.8 Inches
Step-By-Step
1/2 0.835 Inches = 0.4175
r = 0.4175
h = 0.077
A=2πrh+2πr^2
A=2π(0.4175)(0.077)+2π(0.4175^2)
A = 3.12
Nickel = 5 Cents
$2 = 200 Cents
200 / 5 = 40
(3.12)(40) = 124.8 In
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

Answer:
x = 158
Step-by-step explanation:
Given
885 = 5(x + 19) ← divide both sides by 5
177 = x + 19 ( subtract 19 from both sides )
158 = x
Answer: x=158

classify the polynomial according to its degree and number of terms 3x^2+8x
Answers
Answer:
Classifying Polynomials
Polynomials can be classified two different ways - by the number of terms and by their degree.
1. Number of terms.
A monomial has just one term. For example, 4x2 .Remember that a term contains both the variable(s) and its coefficient (the number in front of it.) So the is just one term.
A binomial has two terms. For example: 5x2 -4x
A trinomial has three terms. For example: 3y2+5y-2
Any polynomial with four or more terms is just called a polynomial. For example: 2y5+ 7y3- 5y2+9y-2
Practice classifying these polynomials by the number of terms:
1. 5y
2. 3x2-3x+1
3. 5y-10
4. 8xy
5. 3x4+x2-5x+9
Answers: 1) Monomial 2) Trinomial 3) Binomial 4) Monomial 5) Polynomial
2. Degree. The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).
Examples:
5x2-2x+1 The highest exponent is the 2 so this is a 2nd degree trinomial.
3x4+4x2The highest exponent is the 4 so this is a 4th degree binomial.
8x-1 While it appears there is no exponent, the x has an understood exponent of 1; therefore, this is a 1st degree binomial.
5 There is no variable at all. Therefore, this is a 0 degree monomial. It is 0 degree because x0=1. So technically, 5 could be written as 5x0.
3x2y5 Since both variables are part of the same term, we must add their exponents together to determine the degree. 2+5=7 so this is a 7th degree monomial.
Classify these polynomials by their degree.

Show that the credit card number
4306 0912 4887 1457 is valid/invalid.
Explain how you know.
Answers
Step 1b. For a card with an odd number of digits (e.g., American Express), double alternating digits starting with the second digit in the sequence.
Step 2. If the doubling resulted in a number with two digits, add them together to get a single digit number
Step 3. Now go back to the original credit number and replace the digits that you doubled with the new value — either the doubled value, or the doubled value with the digits added together — and add it all up.
Step 4. Check to see if the sum is evenly divisible by 10 (you can simply look to see whether or not it ends with a zero).
If the card number does not pass this check, then it is not a valid number. If, on the other hand, it does pass, then it may be a valid number with valid credit report.

Step-by-step explanation:
Using the sine ratio in the right triangle
sin50° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{200}{x}[/tex] ( multiply both sides by x )
x × sin50° = 200 ( divide both sides by sin50° )
x = [tex]\frac{200}{sin50}[/tex] ≈ 261 ft ( to the nearest foot )
x ≈ 261 ft

Answer:
=13/3
Step-by-step explanation:
1. Distribute
3+2(4−6)=8+1
3+8−12=8+1
2. Combine like terms
3+8−12=8+1
11−12=8+1
3. Add 12 to both sides of the equation
11−12=8+1
11−12+12=8+1+12
4. Simplify
11=8+13
5. Subtract 8x from both sides of the equation
11=8+13
11−8=8+13−8
6. Simplify
3=13
7. Divide both sides of the equation by the same term
3=13
3x÷3=13÷3
8. Simplify
If you cancel terms that are in both the numerator and denominator you will get:
=13/3

Can someone please help me with math
Answers
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 6 , then
y = 6x + c ← is the partial equation
To find c substitute (2, 19) into the partial equation
19 = 12 + c ⇒ c = 19 - 12 = 7
y = 6x + 7 → B
Answer:
B. y = 6x + 7
Step-by-step explanation:
Since the equation in slope: intercept form, y = mx + b, identify the slope of the line as the coefficient next to the variable x
y = 6x + 7, m = 6
Use the given slope and point to substitute into the point-slope formula
[tex]y - y1 = m (x-x1)[/tex]
Slope: intercept form:
y = 6x + 7
Point-slope form:
y - 19 = 6 (x - 2)

If y varies directly as x and y = 5.5 when x = 11, find x when y = 3.5
0 x = 7
O x = 6
O x = 1.75
O x = 1.25
Answers
Answer:
x=7
Step-by-step explanation:
y=mx
5.5=m×11
5.5÷11=m
m=1/2
y=mx
3.5=1/2×x
3.5÷1/2=x
x=7
Answer:
x =7
Step-by-step explanation:
The direct variation equation is y = kx, where k is the constant of proportionality.
If y = 5.5 when x = 11, we can write 5.5 = 11k, which, when solved for k, yields k = 0.5.
Then the direct variation equation in this case is y = 0.5x.
If y = 3.5, what is x? y = 0.5x becomes 3.5 = 0.5x, yielding x = 7
