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 1

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 2

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

Step-by-step explanation:

Please help me with the questions please ASAP

Answers

Answer:

x = 20

Step-by-step explanation:

You can solve this problem using similar triangles; you know the triangles are similar due to the AAA property because of the Corresponding Angles Theorem.

To find x, you need to identify what sides 8 and x correspond to:

8 corresponds to 14 (6 + 8)

x corresponds to (x + 15)

Now, you need to find the scale factor by dividing 14 by 8:

14 ÷ 8 = 7/4

At this point, you can write and solve an equation for x:

7/4x = x + 15

3/4x = 15 (subtract x from both sides)

x = 20 (multiply both sides by 3/4)

Value of x in isosceles triangle

Answers

Answer:

Step-by-step explanation:

By the Pythagorean Theorem

[tex]52=x^2+16\\ \\ x^2=52-16\\ \\ x^2=36\\ \\ x=\sqrt{36}\\ \\ x=6[/tex]

From the picture we see that the base is 8. The vertical line representing the length of x cuts the base into two equal parts. Knowing this fact allows us to use the Pythagorean Theorem.

(leg)^2 + (leg)^2 = (hypotenuse)^2

(4)^2 + (x)^2 = [sqrt{52}]^2

16 + x^2 = 52

x^2 = 52 - 16

x^2 = 36

sqrt{x^2} = sqrt{36}

x = -6 and x = 6.

We reject x = -6 because length is never negative.

Answer: x = 6

whar are the formulae of - sin , tan , cosec, cos​

Answers

Answer:

Now, the formulas for other trigonometry ratios are: Cot θ = 1/tan θ = Adjacent side/ Side opposite = AB/BC. Sec θ = 1/Cos θ = Hypotenuse / Adjacent side = AC / AB. Cosec θ = 1/Sin θ = Hypotenuse / Side opposite = AC /BC

Sin=Opposite/Hypotenuse

Cosec=Hypotenuse/Opposite
Cos=Adjacent/Hypotenuse

Since ab similar to we than you can do 20 divide by two so that would give you 10 and if you divid 4 by 2 that you give 2 the top is 2 and bottom 8 or 6

Answer:

AB=5

Step-by-step explanation:

Triangle TAB is similar to triangle TWE. This can be proven through AA congruency. Because line AB is parallel to line segment WE, angle TAB is congruent to angle TWE (corresponding angles) and angle TEW is congruent to angle TEW(corresponding angles). Now, having proved that triangle TAB is similar to triangle TWE, we know that similar triangles have proportional sides. We can do [tex]\frac{TB}{AB} = \frac{TE}{WE}[/tex], plug in values for [tex]\frac{4}{AB} = \frac{16}{20}[/tex]  , simplify   [tex]\frac{4}{AB} = \frac{4}{5}[/tex], both fractions have a four in the numerator and must be equal to each other so AB=5.

Answers

It's a good idea to get into the habit of

using parenthses when substituting

numbers in for variables.

Since x = -4 and y = -2, 5x - y is 5(-4) - (-2).

Now, 5(-4) is -20 and minus a negative 2

can be thought of as plus a positive 2.

So we have (-20) + (+2) which equals -18.

Tickets for the amusement park cost $36 each. Which expression can be used to find the cost, in dollars, of k tickets for the amusement park?

Answers

Answer:  36k or 36 * k

Step-by-step explanation:

Each ticket costs $36 each and there are k tickets to b purchased.

To find the cost, you need to multiply the cost of one ticket by the total number of tickets which is k:

= 36 * k

That is the relevant equation.

For instance, assume k is 5. The cost of 5 tickets would be:

= 36 * k

= 36 * 5
