Electric utility poles in the form of right cylinders are made out of wood that costs $25.46 per cubic foot. Calculate the cost of a utility pole with a diameter of 1.5 ft and a height of 30 ft. Round your answer to the nearest cent.

Answers

Answer 1

Answer:

$1349.75

Step-by-step explanation:

Use the equation for volume of a cylinder - pi * radius^2 * height

Halve the diameter to find the radius - 1.5 / 2 = 0.75 ft

Find the volume of the cylinder - pi * 0.75^2 * 30 = 53.0143760293 cubic feet or ft^3

Multiply volume by cost per cubic foot - 53.014... * 25.46 = 1349.746013706

Round to nearest cent = $1349.75

500ml of milk for 60p
4 litres for £3.20
Which bottle is better value for money?

Answers

Answer:

4 liters for £3.20

Step-by-step explanation:

we want to maximize quantity for each unit of money spent. if we use mL and p, we want to maximize mL/p

500 mL = 60 p

divide both sides by 60p to get a mL/p value

500 mL/60 p = 50/6 p ≈ 8.3 mL per pence

4 L = £3.20

note:

1000 mL = 1L

divide both sides by 1 L/ 1000 mL

1000 mL / 1 L = 1

1 L / 1000 mL = 1

100 p = £1

divide both sides by 100p / £1

100p / £1 = 1 = £1 / 100p

convert everything to the same units (mL and p) to accurately compare

4 L = £3.20

4L  = 4L * 1 = 4L * 1000 mL / 1 L = 4000 mL. Note that we have two options to choose from -- 1000 mL / 1 L and 1 L / 1000 mL. We choose the first one here because we want the 4L to cancel out with the 1 L

£3.20 = £3.20 * 1 = £3.20  * 100p / £1 = 320 p. note we put the £1 on the bottom so the euros cancel out.

thus,

4 L = £3.20

= 4000 mL = 320p

divide both sides by 320p to get a mL / p value

4000 mL / 320 p = 12.5 mL/p

8.3 mL per pence in the first one

12.5 mL per pence in the second one

the second one has a higher mL per pence, so that is a better value

B. 35.13 in2
C. 70.26 in2
D. 49,26 in2

Answers

Answer:

C 70.26 in2

Step-by-step explanation:

6 = D

R = D/2

R = 3

A = 3.14 x 3 x 3

A = 3.14 x 9

A = 28.26

The area of the triangle is

A = 6 x 7

A = 42

So

1. The measure of 2G is 82º. What is the
measure of its supplement?

Answers

A supplement adds to 180°, or a straight line..

So the supplement is 98°

Answer:

98º

Step-by-step explanation:

Since a supplementary angle is 2 angles which equal 180 degrees we would have this angle and 1 more angle that add up to 180:

[tex]82+x=180[/tex]

subtract 82 from both sides

[tex]x=98[/tex]

The answer to this expression is [tex]\frac{13x-6}{6}[/tex], or [tex]\frac{13x}{6} - 1[/tex].

Step-by-step explanation:

The given problem is [tex]\displaystyle \frac{2x}{3}+\frac{(3)x-2}{2}[/tex] .

Let's start by finding common denominators for the fractions so that we can add them. The simplest common denominator is 6; we multiply [tex]\frac{2x}{3}[/tex] by [tex]\frac{2}{2}[/tex] and [tex]\frac{3x-2}{2}[/tex] by [tex]\frac{3}{3}[/tex].

[tex]\displaystyle \frac{2x}{3} \times \frac{2}{2} =\frac{4x}{6}[/tex][tex]\displaystyle \frac{3x-2}{2} \times \frac{3}{3} = \frac{3(3x-2)}{6} = \frac{9x-6}{6}[/tex]

Now, since the fractions have common denominators, we can add them together.

[tex]\displaystyle \frac{4x}{6} + \frac{9x-6}{6} = \frac{13x-6}{6}[/tex]

The answer to this expression is [tex]\frac{13x-6}{6}[/tex], or [tex]\frac{13x}{6} - 1[/tex].

Given that the sine of a certain angle is 513, and that the angle lies in quadrant 1 of the coordinate plane, what is the tangent of the angle?

Answers

The question is an illustration of trigonometry ratio, and the tangent of the angle is 12/13

How to determine the tangent of the angle?

Let the angle be x.

The sine of the angle is given as:

sin(x) = 5/13

The sine of an angle is calculated using:

sin(x) = opposite/hypotenuse

By Pythagoras theorem, we have:

Hypotenuse^2 = Adjacent^2 +Opposite^2

This gives

13^2 = Adjacent^2 + 5^2

Rewrite as:

Adjacent^2 = 13^2 - 5^2

Evaluate

Adjacent^2 = 144

Take the square root of both sides

Adjacent = 12

The tangent is then calculated using

tan(x) = Adjacent/Hypotenuse

So, we have:

tan(x) = 12/13

Hence, the tangent of the angle is 12/13
