Eric is preparing for a regional swim meet that is a month away. He swims the same distance and clocks his best time on several different days. He plots the best time (in minutes) he swam each day as his y-variable and the day he swam it as his x-variable. When he plots his times and finds a line of best fit, he gets the equation y=−0.03x+3.45.
If Eric continues to practice, what will be his approximate best time on the 15th day?

A jar contains n nickels and d dimes. There are 20 coins in the jar, and the total value of the coins is $1.50. How many nickels and how many dimes are in the jar?
The jar contains ___ nickels and ___ dimes.
Answer:
The jar contains 10 nickels and 10 dimes. Another answer is that the jar contains 4 nickels and 13 dimes.
Step-by-step explanation:
1 nickels = 5 cents
1 dime = 10 cents
1st answer
10 nickels = $0.50
10 dimes = $1.00
So 10 nickels + 10 dimes = $1.50
2nd answer
13 dimes = $1.30
4 nickels = $0.20
So 13 dimes + 4 nickels = $1.50
-4(1 - 8n) - 4(8n + 4)

What is the solution to the system of equations?
2x+y=11
1/2x-5y=8
please help!!!
Answer: ( x,y ) = ( 96/43, 152/43 )
Step-by-step explanation:
Answer: ( x,y ) = ( 96/43, 152/43 )
Step-by-step explanation:
rewrite the expression
2x + y=8
11 1/2 x X - 5y=8
mixed fraction btw.
simplify
2x + y =8
23x - 10y = 16
multiply both sides
20x + 10y = 80
23x - 10y = 16
eliminate one variable by adding the equations
43x =96
divide both sides
x = 96/43
substitute the value of x
2 x 96/43 + y = 8
solve the equation
y = 152/43
a possible solution is
( x,y ) = ( 96/43, 152/43 )
check solution
simplify
8 = 8 = 8
the ordered paired is a solution!
final answer: ( x,y ) = ( 96/43, 152/43 )
Which expression is equivalent to 12a⁻⁴ b³c⁸/3a⁻² b⁹c⁻²
for all values of a, b, and c where the expression is defined?
To simplify the expression, we can use the laws of exponents:
12a⁻⁴ b³c⁸ / 3a⁻² b⁹c⁻²
= (12/3) (a⁻⁴ / a⁻²) (b³ / b⁹) (c⁸ / c⁻²)
= 4 (a⁻⁴+2) (b³-9) (c⁸+2)
= 4a⁻² b⁻⁶ c¹⁰
Therefore, the expression is equivalent to 4a⁻² b⁻⁶ c¹⁰ for all values of a, b, and c where the expression is defined.

The blue portion of the American flag is known as the union. Using the measurements in the diagram, determine if the rectangle enclosing the union is similar to the rectangle enclosing the entire flag.
They are not similar.
The dimensions of the Union are 3'x5'.
The dimensions of the overall flag are 9-1/2'x5'.
Hope this helps ^^
The rectangle enclosing the union is not similar to the rectangle enclosing the entire flag.
Given that the flag's union portion has dimensions = 18.24 in and 13 in, whereas the entire flag has the dimension = 3.8 ft and 2 ft,
We need to check if the rectangle enclosing the union is similar to the rectangle enclosing the entire flag.
To determine if the rectangle enclosing the union portion of the flag is similar to the rectangle enclosing the entire flag, we can compare their aspect ratios.
The aspect ratio of a rectangle is calculated by dividing its longer side by its shorter side.
In this case, for the union portion of the flag, the longer side is 18.24 inches, and the shorter side is 13 inches.
Thus, the aspect ratio of the union rectangle is:
Aspect ratio of union rectangle = 18.24 in / 13 in ≈ 1.403
For the entire flag, the longer side is 3.8 feet (which is equivalent to 45.6 inches) and the shorter side is 2 feet (which is equivalent to 24 inches). Therefore, the aspect ratio of the rectangle enclosing the entire flag is:
Aspect ratio of entire flag rectangle = 45.6 in / 24 in ≈ 1.9
Since the aspect ratios of the two rectangles are different (1.403 vs. 1.9), we can conclude that the rectangle enclosing the union portion of the flag is not similar to the rectangle enclosing the entire flag.
