The length of the walkway is 24 ft, and you will need 24 stones to cover it.
What is the length of the walkway?
The length of the walkway will be equivalent to the hypotenuse of a right triangle with cathetus of 23ft and 18ft, so we can use the Pythagorean theorem to get it:
L^2 =(23fy)^2 + (18ft)^2
L = √( (23fy)^2 + (18ft)^2 ) = 23.77ft
The walkway is 23.77 ft long.
Rounding to the nearest foot, the length is 24 ft.
b) If each stone covers 1 ft, then you will need 24 stones.

You randomly pull two bills, what is the probability that they are both $20?
Answer:
Depends on the pool you are pulling them from.
There are currently 11 different denomination accessible.
That would be 1 out of 11.
But considering that 4 of those bills are uncommon, the odds become 1 out of 7
Then to pull 2 of the same would mean you multiply 1/11 by 1/11 = 1/121
for the 1/7 it would become 1/49

Find the radius
Volume= 250π³in
Answer:
Volume for a cylinder in this case is
V=˜ πr^2h
So R being radius
H being height
V being volume.
We know the volume is 250π
The height is given in the diagram which is 10.
Plug in the infromation into the formula.
250π = πr^2*10
Simplify and solve for r (radius).
Let’s divide by π on both sides
250 = r^2 * 10
Divide by 10 to get rid of 10
25 = r^2
√25 = r
√25 = 5
The radius is 5
The equation of a line is y = 3 - 4x What is the y-intercept of the line?
help :')
Answer:
y-intercept is 3
The point where the line intercepts the y-axis is (0, 3)
Step-by-step explanation:
Slope-intercept form of a linear equation: [tex]y=mx+b[/tex]
(where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept)
Given equation of line: [tex]y=3-4x[/tex]
Rearrange: [tex]y=-4x+3[/tex]
Therefore, the slope of the line is -4 and the y-intercept is 3.
FYI the line intercepts the y-axis when x = 0, so you can input x = 0 into the equation to find y ⇒ (0, 3)
Answer:
The y-intercept of the line is 3.
Step-by-step explanation:
Formula: y = mx + b
y = 3 - 4x
y = -4x + 3
On the formula, "b" means y-intercept. Therefore, the y-intercept of the line is 3.
A store offers discounts on lunch-size chip bags when buying larger quantities. The graph below represents the total cost, in dollars, for the number of bags purchased.
What is the difference in the price per bag for 150 bags versus 50 bags?
The difference in the price per bag for 150 bags versus 50 bags is $0.15 per bag.
What is the difference in the price of the bags?If 150 bags on the x axis is traced to the y axis, the price of the bag is $38.
If 50 bags on the x axis is traced to the y axis, the price of the bag is $20.
Price per bag:
150 bags = 38 / 150 = $0.25
50 bags = $20 / 50 = $0.4
The difference = $0.4 $0.25 = $0.15

After making repairs, a swimming pool owner is going to refill the pool with water. The pool's dimensions are 18\times40\times618×40×6 feet, with each cubic foot equivalent to 2.642.64 gallons, and the cost of water \$0.005$0.005 per gallon. To the nearest dollar, what is the estimated cost of filling the pool?
Answer:
$57
Step-by-step explanation:
I'll assume the pool's dimensions are 18 x 40 x 6.
The total volume is (18 x 40 x 6) = 4320 ft^3.
Use the conversion factor (2.64 gallons/1 ft^3) to find the gallons of water in a full pool. Full pool, cool.
Water (gal) = (4320 ft^3)*(2.64gallons/ft^3) = 11,405 gallons
At $0.005/gal, this would cost (11,405 gallons)*($0.005/gal) = $57.02
$57 to the nearest dollar.
Find the area of each figure. Round your answer to the nearest tenth
Answer:
62
Step-by-step explanation:
step 1: find the height of half the yellow coloured triangle (right angled triangle). remember that the angle formed at the center is always 36° for a pentagon.
tan36° = opposite/ adjacent
tan36° = 3/h (h for height)
h × ( tan36°) = 3
h = 3 / tan36°
h = 4.13
step 2: calculate area of the right angled triangle
Area = 1/2 × b × h
= 1/2 × 3 × 4.13
= 6.195
step 3: calculate the area of a Pentagon
a Pentagon can be divided into ten right angled
triangle
6.195 × 10
total area = 61.95
rounded off = 62

What is the circumference of a circle with a radius of 3.6 units,I don’t really know how to do this because I’m new to this kind of math.
Answer:
22.608 units
Step-by-step explanation:
Basically, the circumference of a circle is the distance around a circle, sort of like the perimeter of a figure. It has a unique formula which is [tex]C=2\pi r[/tex] where [tex]r[/tex] is the radius, which is the distance between the circle and its center. Using our given information, we can find the circumference:
[tex]C=2\pi r\\C=2(3.14)(3.6)\\C=22.608[/tex]
Therefore, the circumference of a circle with a radius of 3.6 units is 22.608 units.
Answer:
Circumference is...
22.608Step-by-step explanation:
Multiply the radius by 2 to get the diameter.
Multiply the result by π, or 3.14 for an estimation.
That's it; you found the circumference of the circle.

A library has an aquarium in the shape of a rectangular prism. The base is 6 ft by 2.5 ft. The height is 4 ft. How many square feet of glass was used to build the aquarium?
Step-by-step explanation:
Solve the problem step by step.
First,
Base area: 6 * 2.5 = 15
Then,
The area of the two smallersides:
2.5 * 4 = 10
10 * 2 = 20
After that,
The area of the two larger sides:
6 * 4 = 24
24 * 2 = 48
After all of the calculations, you add all of the sums up:
15+20+48
Which equals 83.
The equation form for this problem would be:
(6*2.5) + 2(2.5*4) + 2(6*4) = 83
Hope this helps and it wasn't too confusing!

The relative frequency of Event A in an experiment is 20%. If the experiment is performed 40 times, how many times should you expect Event A to occur?
Enter your answer as a number, like this: 42
Step-by-step explanation:
look at a die, for example.
the probabilty to roll a 6 is 1/6 (if all numbers truly have the same probability due to a perfectly balanced die).
so, you expect as a mean value that you have to roll the die 6 times to get one 6.
now in our general example :
20% = 1/5
so, we expect event A to happen once as a mean value every 5 attempts.
now we do 40 attempts. that means 8×5 sets of attempts.
and we therefore expect to see event A 8 times.
