By using the similar triangles principle, the height of the building is found to be 132 meters. We find this by setting up a proportion between the known ratios of the pole's height to its shadow and solving for the building's height.
Explanation:We can solve the problem using similar triangles. The ratio of the height of the pole to its shadow is the same as the ratio of the height of the building to its shadow. Since the height of the pole is 6m and its shadow is 10m, we have the ratio of the height to the shadow for the pole as 6/10 or 3/5.
This ratio will be equal to the ratio of the height of the building (which we'll call h) to the shadow of the building (220 m), so we can write the proportion as:
3/5 = h/220
Now we solve for h:
3/220 = h/5
h = (3/5) × 220
h = (3 × 44)
h = 132m
So the height of the building is 132m.

castor collects only baseball and football cards. He has 40 baseball cards and 10 football cards. Which decimal best show the part of his entire card collection represented by his baseball cards
Answer: His baseball cards can be represented as 0.8 of the entire collection
Step-by-step explanation: Castor has 40 baseball cards and 10 football cards. Therefore his total number of cards is given as 40 + 10 which is 50.
The fraction of his cards which are baseball cards only is calculated as
Baseball cards = 40/50
Baseball cards = 4/5
Converting 4/5 to a decimal (which can equally be done with a calculator) gives you 0.8
Hence, the part of his entire card collection that can be represented by baseball cards is 0.8

Cathy has 39 coins, which are either nickels or quarters. If she has $4.95, how many nickel coinsdoes she have? _____ nickels
Answer: 24 nickels
Step-by-step explanation:
1. n= nickels
q=quarters
2. n+q=39
.05n+.25q=4.95
3. n=39-q (Replace n with what n is equal to in the other equation) .05(39-q)+.25q=4.95
4. Solve for q: (.05x39)+(.05x-q)+.25q=4.95
5. 1.95-.05q+.25q=4.95 (Combine like terms)
6. 1.95+(-.05q+.25q)=4.95
7. 1.95+0.2q=4.95
8. Move 1.95 to the other side of equal sign by subtracting it from both sides. 0.2q=3
3/0.2= 15... so quarters=15
So if you look back at the other equation it says n+q=39. So, 39-15=24. There is 24 nickels.

It costs $5 to get into the fair and then costs $3 for every ride I go on.
I spent a total of $26. Write an equation that could be used to show
the number rides, r, that I went on.
Final answer:
To find the number of rides that you went on at the fair given the total cost, $26, and the cost per ride, $3, you can use the equation $26 = $5 + $3r. Solving for r, you find that you went on 7 rides.
Explanation:
To write an equation that shows the number of rides, r, that you went on, we need to consider the total cost you spent and the cost per ride.
The cost to enter the fair is $5, and for every ride you go on, it costs $3. So, the equation would be:
Total Cost = Cost to Enter + Cost per Ride x Number of Rides
In this case, you spent a total of $26. Plugging in the values, we get:
$26 = $5 + $3r
Now, we can solve for r by isolating the variable:
$26 - $5 = $3r
$21 = $3r
To find the number of rides, divide both sides by $3:
r = $21/$3
r = 7
Therefore, you went on 7 rides at the fair.

A unicycle wheel has a diameter of 25 inches. How many inches will the unicycle travel in 4 revolutions?
Use T = 3.14 and round your answer to the nearest
hundredth of an inch
Answer:
The distance travelled was 314 inches.
Step-by-step explanation:
In order to calculate the distance that the unicycle will travel in 4 revolutions we first need to know the length of it's wheel, this is calculated by using the formula bellow:
length = 2*pi*r
Where r is the radius of the wheel that is equal to r = d/2
length = 2*pi*(d/2) = 2*3.14*(25/2) = 3.14*25 = 78.5 inches
If the wheel made 4 complete revolutions then the distance travelled was 4 times the length of it's wheels. We have:
distance = 4*length = 4*78.5 = 314 inches
The distance travelled was 314 inches.

A. The boxes weigh the same amount.
B. Box B weighs 0.10 of a kilogram more
than Box A.
Box A weighs 0.15 of a kilogram more
than Box B.
D. Box B weighs 0.21 of a kilogram more
than Box A.
Box A, weighing 212.04 kilograms, is 0.04 kilograms heavier than Box B, which weighs 212 kilograms. The difference in weight is due to differing volume and density.
Explanation:The question is asking us to compare the weight of two boxes, Box A and Box B. Box A weighs 212.04 kilograms and Box B weighs 212 kilograms. To compare the weights, we subtract the weight of Box B from that of Box A: 212.04 kg - 212 kg = 0.04 kg. Therefore, the correct statement is: Box A weighs 0.04 of a kilogram more than Box B.

What are the lateral area and the surface area of the cone shown below? Round the answers to the nearest tenth. The figure is not drawn to scale.
A. LA = 615.8 ft2; SA = 1,803.3 ft2
B. LA = 615.8 ft2; SA = 3,166.7 ft2
C. LA = 1,187.5 ft2; SA = 1,803.3 ft2
D. LA = 1,187.5 ft2; SA = 3,166.7 ft2
Given:
The radius of the cone = 14 ft
The slant height of the cone = 27 ft
To find the lateral surface area and the total surface area of the given cone.
Formula
The lateral surface area of the cone is
[tex]LSA = \pi rl[/tex] and
The total surface area of the cone is
[tex]TSA = \pi r^{2} + \pi r l[/tex]
where,
r be the radius and
l be the slant height of the cone.
Now
Taking r = 14 and l = 27 we get
[tex]LSA = \pi (14)(27)[/tex] sq ft
or, [tex]LSA = 1187.5[/tex] sq ft
Again,
[tex]TSA = \pi(14^2)+\pi (14)(27)[/tex] sq ft
or,[tex]TSA = 1803.3[/tex] sq ft
Hence,
The lateral surface area of the cone is 1187.5 sq ft and the total surface area of the cone is 1803.3 sq ft. Option C.
Gavin and Jim win some money and share it in the ratio 5:2. Gavin gets £39 more than Jim. How much did they get altogether?
Final answer:
To find the total amount of money Gavin and Jim got all together, we need to solve the equation 5x = x + £39, where x represents the amount Jim received. The total amount is £58.50.
Explanation:
To find the total amount of money that Gavin and Jim got altogether, we need to first determine the amounts they each received. Let's say the amount Jim received is represented as 'x'. According to the ratio of 5:2, Gavin received 5 times the amount Jim received, so Gavin received 5x.
We're given that Gavin gets £39 more than Jim, so we can set up the equation: 5x = x + £39. Simplifying this equation, we get 4x = £39. Dividing both sides by 4, we find that x = £9.75.
Now, we can calculate the total amount they got altogether by adding the amounts Jim and Gavin received: £9.75 + 5(£9.75) = £9.75 + £48.75 = £58.50.
A man wants to beautify his front yard by planting four 20−foot-tall palm trees alongside his house. Each tree will need a cylindrical hole that is 34 inches in diameter and 28 inches deep to accommodate the roots. His trash hauler will only take away the excess dirt if it is in rectangular bags that are 2 feet by 1.5 feet by four feet. However, the man can only fill the bags one third of the way or they will be too heavy for him to move. How many bags will he have to buy so he can put all the dirt out for pickup?
He have to buy 4 bags to put all the dirt at once.
Step-by-step explanation:
Radius = 17 inches
Height = 28 inches
Volume of dirt from the cylindrical hole = π(r x r) h
= π(17 x 17) 28
= (3.14) (289) 28
= 25408.88 cubic inches
1 foot = 12 inches
Volume of dirt the bag can hold= 24 x 18 x 48
= 20736 cubic inches of dirt
The man fills only one third of the bag.
The volume of dirt the man fills = (1/3)20736
= 6912 cubic inches
Total bags = 25408.88/6912
= 3.69
= appx. 4 bags
He have to buy 4 bags to put all the dirt at once.
