Speed is the change in distance of a body with respect to time.
Speed = Distance/Time
If the library made a copy of leslie's 3 page essay in just 1/10 of a minute, this means that she made 3 pages in (1/10 * 60)secs i.e 6secs
To get the speed, we need to calculate the amount of page of essay that are produced in a minute (60secs).
If 3 page essay = 6secs
x page essay = 60 secs
cross multiply
3*60 = 6x
180 = 6x
x = 180/6
x = 30
This shows that 30 page essays are produced in just a minute. Hence the speed of the copy machine is 30page essay/min.

You want to rent a car. The cost is $120 per day. You are allowed 100 miles per day--but any mileage above that amount will cost $0.35 per mile. You rent the car for 5 days, and drive 925 miles. The car gets 25 miles to the gallon, and a gallon of gas costs $4.
pls help im so confused
Answer:
600$ rent for 5 days,
around 185 miles a day, meaning you are paying 0.35$x85=29.75 extra a day.
adding up to 120 a day+29.75=149.75 a day.
149.75x5=748.75 for 5 days not including gas prices.
925/25=185 gallons of gas. 4 dollars per gallon, meaning that 185x4=740 extra dollars in gas
748.75+740=1488.75$ for the entire trip.
1488.75

Area = length x width
area of files = 30 x 20 = 600 square feet
area of unmoved field = 16 x 26 = 416 square feet
area that was mowed = 600 - 416 = 184 square feet
answer: 184 square feet
Answer:
184 ft
Step-by-step explanation:
so, for this, the key is the smaller dimentions on the inside, they are the area of the smaller inner rectangle (416 ft) and the bigger dimentions on the outside, are for the entire rectangle including the mowed area (600 ft), but you dont know the exact value of the mowed area, so you would simply subtract the areas (600-416=184) and that number, 184, is the area of the mowed area that you didnt know.

Find the volume of the cylinder. Explain or show your reasoning. All measurements are in centimeters
Answer:
200π cm³ (in term of π)
628 cm³ (when define π = 3.14)
Step-by-step explanation:
Given:
radius of circular base = 5height = 8Volume of Cylinder:
[tex]\displaystyle \large{V=\pi r^2h}[/tex]
If you notice, the volume of cylinder is area of circular base * height.
Input given information in the formula:
[tex]\displaystyle \large{V=\pi \cdot 5^2 \cdot 8}[/tex]
Evaluate:
[tex]\displaystyle \large{V=\pi \cdot 25 \cdot 8}\\\displaystyle \large{V=200 \pi}[/tex]
Since all measurements are in centimeters. Therefore, our unit is cm³ since we are finding volume which is three-dimensional.
Fact
cm is used for one-dimensional measurement such as line.cm² is used for two-dimensional measurement such as area.cm³ is used for three-dimensional measurement such as volume.However, you didn’t specific which π value/digit should we use so I’ll only put both solutions in where first being in term of π and second being 3.14.
Therefore, the volume is:

What is the mean for this list of numbers 4,8,12,13
Answer:

In order to find the mean you must add all of the values together and then divide by the number of numbers. 4 + 8 + 12 + 13 = 37
Now we divide: 37 ÷ 4 = 9.25
So the mean is 9.25

15-9 to find a^2, 4 is b^2, and then pythagorean thereoum, a^2+b^2=c^2.
Answer:
Step-by-step explanation:
The base of the triangle used to solve for x (Pythagorean Theorem) is 15 - 9 = 7
The height of the right triangle is 4 so now you have enought to solve for x
Givens
a = 7
b = 4
c = x
Equation
x^2 = b^2 + a^2
Solution
x^2 = 7^2 + 4^2
x^2 = 49 + 16
x^2 = 65 Take the square root of both sides
√x^2 = √65
Answer x = √65

necessary to make an umbrella?
1) volume of a sphere
2) surface area of a sphere
3) volume of a hemisphere
4) surface area of a hemisphere

Answer:
A. The student earned $18 for cleaning out his neighbor's garage.
Step-by-step explanation:
Since given that A student spent $18 for a haircut this week and asking for Which event, when combined with the student spending $18, will result in the student having $0 remaining
Thus, we know that spending is negative because we are using it so it -18
Base on the given answer choice below we can infer that
earned = +
Paid = -
Purchased = -
Gave = -
The only way to make it back with a $0 is to add $18
Thus the answer is A. The student earned $18 for cleaning out his neighbor's garage.

In the figure, AC = BC. Find the value of b.
Since AC = BC, we can say that this triangle is isoceles (at C)
In an isoceles triangle, the two angles that does not belong to the top angle (which in this case is C) is equal to each other.
Now, we can find the sum of the 2 missing angles : 180 - 52 = 128.
And since they are equal, we can find b : 128 : 2 = 64/

The following three shapes are based only on squares, semicircles, and quarter circles. Find the perimeter and the area of each shaded part.
Answer:
Step-by-step explanation:
The total shaded area = area of the square - area of a circle
= 9^2 - π * 4.5^2
= 17.3827
The 2 shaded parts both have area 8.69 unit^2 ( to nearest hundred)
Perimeter:
The perimeter of the top shaded part
= AB + 1/2 circmference of the circle
= 9 + 1/2 * 2 π r
= 9 + 14.137
= 23.14 units ( to nearest hundredth)
The bottom part has the same perimeter.
Answer:
area: 17.38 cm²perimeter: 46.27 cmStep-by-step explanation:
You want the perimeter and area of the part of a 9 cm square remaining after a semicircle is removed from two opposite sides.
AreaThe shaded area is the area of the 9 cm square less the area of a 9 cm circle. That area is ...
A = s² - π(s/2)² = s²(1 -π/4) . . . . . where s is the side length of the square
A = (9 cm)²(1 -π/4) ≈ 17.38 cm²
The area is about 17.38 cm².
PerimeterThe perimeter is the circumference of the circle plus two sides of the square.
P = C +2s
P = πs +2s = s(π+2)
P = (9 cm)(π+2) ≈ 46.27 cm
The perimeter is about 46.27 cm.
