Last year there were 120 campers at camp sleep-a-way. This year they will expect 150.By what percentage did the campers increase?
Answer:
[tex]\%Increase = 25\%[/tex]
Step-by-step explanation:
Given
[tex]Last\ Year = 120[/tex]
[tex]This\ Year = 150[/tex]
Required
Determine the percentage increase
This is calculated as thus:
[tex]\%Increase = \frac{This\ Year - Last\ Year}{Last\ Year} * 100\%[/tex]
[tex]\%Increase = \frac{150 - 120}{120} * 100\%[/tex]
[tex]\%Increase = \frac{30}{120} * 100\%[/tex]
[tex]\%Increase = 0.25 * 100\%[/tex]
[tex]\%Increase = 25\%[/tex]

which equation has n=18 as a solution
A. 14+n=29
B. 6n=3
C. 25=n-7
D n/2=9
Answer:
D n/2 = 9
Step-by-step explanation:
14 + (18) = 32 not 29
6(18)= 108 NOT 3
18 - 7 = 11 NOT 25
The only answer is D because 18 divided by 2 = 9

Step-by-step explanation:
A 2000 gallon fish aquarium can be filled by water flowing at a constant rate in 10 hours. When a decorativve rock is placed in the aquarium, it can be filled in 9.5 hours. Find the volume of the rock in cubic feet
Answer:
The volume of the rock is 13.368 cubic feet.
Step-by-step explanation:
The volume of the rock ([tex]V_{r}[/tex]), measured in gallons, is equal to the volume of the fish aquarium without the decorative rock ([tex]V'[/tex]) minus the volume of the fish aquarium with the decorative rock ([tex]V''[/tex]), both measured in gallons.
Since the water flow is at constant rate, the volume of the rock is expressed by the following equation:
[tex]V_{r} = V' - V''[/tex]
[tex]V_{r} = \dot V \cdot (\Delta t_{1}-\Delta t_{2})[/tex] (1)
Where:
[tex]\dot V[/tex] - Flow rate, measured in gallons per hour.
[tex]\Delta t_{1}[/tex] - Filling time of the fish aquarium without the decorative rock, measured in hours.
[tex]\Delta t_{2}[/tex] - Filling time of the fish aquarium with the decorative rock, measured in hours.
And the flow rate is:
[tex]\dot V = \frac{2000\,gal}{10\,h}[/tex]
[tex]\dot V = 200\,\frac{gal}{h}[/tex]
The flow rate is 200 gallons per hour.
If we know that [tex]\dot V = 200\,\frac{gal}{h}[/tex], [tex]\Delta t_{1} = 10\,h[/tex] and [tex]\Delta t_{2} = 9.5\,h[/tex], then the volume of the rock is:
[tex]V_{r} = \left(200\,\frac{gal}{h}\right)\cdot (10\,h-9.5\,h)[/tex]
[tex]V_{r} = 100\,gal[/tex]
[tex]V_{r} = 13.368\,ft^{3}[/tex]
The volume of the rock is 13.368 cubic feet.
Brenda is deciding between two landscaping companies for her place of business. Company A charges $25 per hour and a $300 equipment fee. Company B charges $50 per hour and a $150 equipment fee. Let AA represent the amount Company A would charge for tt hours of landscaping, and let BB represent the amount Company B would charge for tt hours of landscaping. Write an equation for each situation. Determine the interval of hours, t,t, for which Company A is cheaper than Company B.
Answer:
1/6 hours
Step-by-step explanation:
Given data
Company A charges
$25 per hour and a $300 equipment fee
let the number of hours be t
and the total charges be A
A=25+300t----------------1
Company B charges $50 per hour and a $150 equipment fee.
let the number of hours be t
and the total charges be B
y=50+150t----------------2
Equate 1 and 2 we have
25+300t= 50+150t
300t-150t= 50-25
150t= 25
divide both sides by 150
t= 25/150
t=1/6 hours

-8 divided by -5 in fraction form
Answer:
8 / 5
Step-by-step explanation:
-8 / -5 = 8 * -1 / 5 * -1 = 8 / 5
Thank, 5 star, and brainliest if helpful
The fraction (-8)/(-5) simplifies to 8/5 which represents that the quotient is 8 units for every 5 units.
To divide -8 by -5 in fraction form, we can write it as (-8)/(-5). When dividing two negative numbers, the negative signs cancel out, resulting in a positive quotient. So (-8)/(-5) is equal to 8/5.
When we divide -8 by -5, we subtract -5 from -8 repeatedly until we can no longer subtract without going below zero.
This happens after one subtraction, resulting in a quotient of 1.
However, since both numbers are negative, the quotient is positive.
Therefore, (-8)/(-5) simplifies to 8/5.
In fraction form, 8/5 represents the result of dividing -8 by -5, indicating that the quotient is 8 units for every 5 units.

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
a is a leg b is another leg c is the hypotenuseStep-by-step explanation:
Step 1: Identify Variables
Leg a = 9
Leg b = 3
Hypotenuse c = x
Step 2: Solve for x
Substitute [PT]: 9² + 3² = x²Rearrange: x² = 9² + 3²Exponents: x² = 81 + 9Add: x² = 90Isolate x: x = 3√10To find the value of x we can apply Pythagoras theorem in this right angled triangle.
So let's apply!
[tex]{ \boxed{ \sf{ \mapsto {Hypotenuse}^{2} ={Base }^{2} +{Perpendicular }^{2} }}}[/tex]
[tex] \sf{ : \implies {x}^{2} = {9}^{2} + {3}^{2} }[/tex]
[tex] \sf{ : \implies {x}^{2} = 81 + 9 }[/tex]
[tex] \sf{ : \implies {x}^{2} = 90 }[/tex]
[tex] \sf{ : \implies {x} = \sqrt{2 \times 3 \times 3 \times 5} }[/tex]

It means the polygon is similar.
Similar polygons have the same shape but different sizes.
Thus, the given two polygons will have their corresponding sides are in proportion.
so
AB/AE = FG/FK
here
AB = 4, AE = x, FG = 8, FK = 10
so substituting AB = 4, AE = x, FG = 8, FK = 10
4/x = 8/10
8 × x = 4 × 10
8x = 40
divide both sides by 8
8x/8 = 40/8
x = 5
Therefore, the value of x = 5

Answer:
4 horses
Step-by-step explanation:
There are 2 elephants and 4 horses on one side. On the other, there are 12 horses. You can cancel 4 horses so now it's 2 elephants and 8 horses. To get the first side (2 elephants) to turn into one elephant, you need to divide by 2. So now, it is 1 elephant = 4 horses.
Answer:
4
Step-by-step explanation:
4 because you can write the problem as 2e+4h=12h then you subtract 4h from both sides and get 2e=8h then you divide by 2 to get e=4 so one elephant is as strong as 4 horses
h=horses
e=elephant

The roller coaster has a mass of 600 kg and has a potential energy of 46,000J. What is the height of the roller coaster car?
Answer:
The height of the roller coaster car is: h = 7.8 m
Step-by-step explanation:
Given
Mass m = 600 kg
Potential Energy P.E = 46,000J
To determine
Height h = ?
Using the formula
P.E = mgh
Here:
m is the massg is the gravitational acceleration (9.8 m/s²)h is the heightso substituting m = 600 kg, P.E = 46,000J, and g = 9.8
P.E = mgh
46000 = 600 × 9.8 × h
h = 46000 / 5880
h = 7.8 m
Therefore, the height of the roller coaster car is: h = 7.8 m
