[tex]60*0.5=30min\\2.\\60*0.1=6min\\\\3.\\60*0.75=45min[/tex]
Answer:
50% of 60 minutes is 30,
10% of 60 minutes is 6,
75% of 60 minutes is 45.
Step-by-step explanation:
50 is half of 100 so 30 would be half of 60.
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.

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
planes X and Y are perpendicular. Points A,E,F and G are points only in plane X. Points R and S are points in both planes X and Y. Lines EA and FG are parallel.
Based on this information, which pair of lines, together, could be perpendicular to RS? Select two options.
EA
ER
EF
FG
FS
Answer:
FG
Step-by-step explanation:
I did this on my computer
The pair of the line together, could be perpendicular to RS should be considered as the EA and FG.
What is perpendicular?In terms of elementary geometry, two geometric objects should be considered as the perpendicular when they intersect at a right angle. A line is treated to be perpendicular to another line in the case when the two lines intersect at a right angle.
Therefore, The pair of the line together, could be perpendicular to RS should be considered as the EA and FG.

Think about whether these ordered pairs represent a function. Then use the drop-
down menus to complete the statement about the ordered pairs.
(-2,4), (5,6), (0,1), (8, – 7), (9,1)
Answer: All x-coordinates are different, so this relation is a function.
Having the same y value more than once is not a problem for a function.
"This (does not/does) represents a function because different (x values/y values) can have the same (x values/y values)."

Given that n is an interger and that n>1 prove algebraically that n^2-(n-2)^2-2 is always an even number
Answer and Step-by-step explanation:
If n is assumed to be an even number, then obviously the expression will be even because the square of an even number is even and subtracting 2 from an even number makes it remain an even number. Therefore, let's assume n is not an even number, then n = 2x + 1 where x > 0. We have:
(2x + 1)² – (2x + 1 – 2)² – 2 = (2x + 1)² – (2x – 1)² – 2 = 4x² + 4x + 1 – (4x² – 4x + 1) – 2 = 4x² + 4x + 1 – 4x² + 4x – 1 – 2 = 8x – 2 = 2(4x – 1). Since the product is a multiple of 2, then the expression is even if n is odd. Therefore the expression is always even.

The local supermarket is having a holiday special on lollipops. The rainbow lollipops, x, cost $2 and the blue lollipops, y, cost $1. At the end of the day, the supermarket sold a total of 185 lollipops with a total profit of $320. Given the system of equations below, find the solution and what it means in context to the situation. 2x+y=320 y=-x+185 *
Answer:
135 rainbow lollipops were sold ($270) and 50 blue lollipops were sold ($50).
Step-b-step explanation:
Cost of rainbow lollipops: 2
Cost of blue lollipops: 1
2x + y = 320
x + y = 185, y = 185 - x
Solve with substitution:
2x + (185 - x) = 320
x = 135
y = 50
