What is the surface area of the right cone below?

Answers

Answer:

176π [tex]units^{2}[/tex]

Step-by-step explanation:

SA = B + LA  where B is the area of the base (circle) and LA is the lateral area

LA = radius of the circle times the slant height

    = 8π(14) = 112π

B = [tex]8^{2} \pi[/tex] = 64π

SA = 112π + 64π = 176π

The surface area of the right cone is 176π square units.

How to calculate the surface area of a composite figure?

Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, cone etc.

When some shape comes which isn't standard figure, then we find its area by slicing it (virtually, like by drawing lines) in standard shapes. Then we calculate those composing shapes' area and sum them all.

Thus, we have:

[tex]\text{Area of composite figure} = \sum (\text{Area of composing figures})[/tex]

That ∑ sign shows "sum"

We are given that;

The surface area of a right cone is given by the formula:

Surface area=πr(r+l)

where r is the radius of the base and l is the slant height of the cone12.

In this case, r=8 and l=14, so we can plug these values into the formula and simplify:

Surface area=π×8(8+14)

Surface area=π×8×22

Surface area=176π

Therefore, the surface area will be 176π square units.

Which of the following points satisfies the linear inequality below? Select all correct answers.
5x + 2y 26
Select all that apply:
(0,5)
(3,1)
(3,-4)
(-4,1)

Answers

Answer:

All points satisfy the inequality

Step-by-step explanation:

Given

[tex]5x + 2y \le 26[/tex]

Required

Select all points that satisfy the above inequality

[tex](a)\ (0,5)[/tex]

This implies that

[tex]x = 0; y = 5[/tex]

So, we have:

[tex]5x + 2y \le 26[/tex]

[tex]5 * 0 + 2 * 5 \le 26[/tex]

[tex]0 + 10 \le 26[/tex]

[tex]10 \le 26[/tex]

This satisfy the inequality

[tex](b)\ (3,1)[/tex]

This implies that

[tex]x = 3;\ y =1[/tex]

So, we have:

[tex]5x + 2y \le 26[/tex]

[tex]5 * 3 + 2 * 1 \le 26[/tex]

[tex]15 + 2 \le 26[/tex]

[tex]17 \le 26[/tex]

This satisfy the inequality

[tex](c)\ (3,-4)[/tex]

This implies that:

[tex]x = 3; y-4[/tex]

So, we have:

[tex]5x + 2y \le 26[/tex]

[tex]5 * 3 + 2 * -4 \le 26[/tex]

[tex]15 -8 \le 26[/tex]

[tex]7 \le 26[/tex]

This satisfy the inequality

[tex](d)\ (-4,1)[/tex]

This implies that:

[tex]x = -4; y =1[/tex]

So, we have:

[tex]5x + 2y \le 26[/tex]

[tex]5 * -4 + 2 *1 \le 26[/tex]

[tex]-20 + 2 \le 26[/tex]

A grocer wants to mix two kinds of coffee. One kind sells for $0.85 per pound, and the other sells for $2.70
per pound. He wants to mix a total of 21 pounds and sell it for $0.95 per pound. How many pounds of
each kind should he use in the new mix? (Round off the answers to the nearest hundredth.)

Answers

Answer:

x = $0.85 per pound = 19.85 pounds

y = $2.70 per pound = 1.14 pounds

Step-by-step explanation:

Let

x = $0.85 per pound

y = $2.70 per pound

x + y = 21 (1)

0.85x + 2.70y = 19.95 (2)

From (1)

x = 21 - y

Substitute x = 21 - y into (2)

0.85x + 2.70y = 19.95 (2)

0.85(21 - y) + 2.70y = 19.95

17.85 - 0.85y + 2.70y = 19.95

- 0.85y + 2.70y = 19.95 - 17.85

1.85y = 2.1

y = 2.1 / 1.85

y = 1.14

Substitute y = 1.14 into (2)

0.85x + 2.70y = 19.95

0.85x + 2.70(1.14) = 19.95

0.85x + 3.078 = 19.95

0.85x = 19.95 - 3.078

0.85x = 16.872

x = 16.872 / 0.85

x = 19.85

x = $0.85 per pound = 19.85 pounds

y = $2.70 per pound = 1.14 pounds

A solid figure is composed of a cube and a pyramid as shown. What is the volume

Answers

Answer:

288 in^3

Step-by-step explanation:

1) find the volume of the cube

V = side^3 = 6^3 = 216 in^3

2) find the base surface of the pyramid:

base surface = side^2 = 6^2 = 36 in^2

3) find the height of the pyramid:

height of the solid - height of the cube = 12 - 6 = 6 in

4) find the volume of the pyramid:

V = (base area x height) / 3 = (36 x 6)/3 = 72 in^3

5) add up the two volumes

V = 216 + 72 = 288 in^3

The perimeter of a triangle is 29. One side of a triangle is 5 less than twice the side of the shortest length. The third side is 6 more than the shortest side. What are the lengths of the triangle?

Answers

Answer:

7, 9, 13

Step-by-step explanation:

Let the sides of the triangle be a, b and c.

We have:

P = a + b + c = 29a = 2b - 5c = b + 6

Substitute values and solve for b:

2b - 5 + b + b + 6 = 294b + 1 = 294b = 28b = 7

Find a and c:

a = 2*7 - 5 = 14 - 5 = 9c = 7 + 6 = 13

The sides are: 7, 9, 13

The volume of a cuboid is 176cm
The length is 11 cm and the width is 20mm
Work out the height of the cuboid in cm.

Answers

Answer:

.08cm or 0.08cm

Step-by-step explanation:

First of all, we can see that 20mm is in millimeters, not centimeters.

If we convert the ones in centimeters to millimeters, it will result in decimals, which I want to avoid, but you could also do it that way.

There are 10 mm in 1 cm, so I multiply all of the values in cm by 10.

So now, we have that the volume is 1760mm, the length is 110mm, and the width is 20mm.

The formula for the volume of a cuboid is: [tex]w*l*h = volume[/tex]

We have the width, length, and volume, so let's plug it in.

[tex]20*110*h=1760[/tex]

To solve for h:

1. Multiply 20 and 100

[tex]2200*h=1760[/tex]

2. Divide both sides by 2200

[tex]h = 1760/2200[/tex]

3. Divide right side

h = 0.8

Keep in mind that this is in millimeters. In centimeters, it would be .08

A new pair of shoes is advertised for $110. The sales tax is 7.5%. What is the total cost of the shoes?

Answers

Answer:

Step-by-step explanation

If the tax is in percent, divide the tax rate by 100. You do this by moving the decimal point two spaces to the left. In this, there's 7.5/100 = 0.0

Find the tax value by multiplying tax rate by the item value:

tax = 110 × 0.075

Amelia invested $9,800 in an account paying an interest rate of 4 3 4 4 4 3 ​ % compounded continuously. After 20 years, how much more money would Amelia have in her account than Melanie, to the nearest dollar?

Answers

After 20 years, the amount of Money Amelia would have more than Melanie would be $181,551.37.

What is the future value of Melanie's account?

The formula for calculating future value:

FV = P (1 + r) nm

FV = Future value P = Present value R = interest rate = 4 1/2 ÷ 4 = 1.125%m = number of compounding = 4N = number of years

9800(1 + 0.0125)^80 = 23,983.29

What is the future value of the amount in Amelia's account?

the formula for calculating future value when there is continuous compounding is : A x e^r x N

Where:

A= amount e = 2.7182818 N = number of years r = interest rate

9800 e^0.0475 x 20 = 205,534.66

Difference = 205,534.66 - 23,983.29 = $181,551.37
