Answer:
b=7/33 c= 14/33
Step-by-step explanation:
Repeat all 21 they are repeating decimals
for b its 100x-x=21.21 repeating the 21 -0.21 repeating the 21 = 100x-1x=(21+0.21)-0.21= (100-1)x=21+0.21-0.21 [ stop repeating the 21's up to here] and 99x=21+0 = 99x=21 = 99x/99=21/99 both 99's cancel leaving 3x7 divided by 3x33 = x= cancel both 3's leaving 7 over 33 This should help you learn to solve c good luck

Given that n is an interger and that n>1 prove algebraically that n^2-(n-2)^2-2 is always an even number
Answers
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 *
Answers
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
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
Answers
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.

The value of x = 5
Step-by-step explanation:
Given
ABCDE ~ FGHJK
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
