Opposite rays connected at their endpoint form a line. A line is continuous infinitely in both directions.
Answer:
12. C. 40 more students chose baseball than basketball
20. 500 total flowers
Step-by-step explanation:
12. To find the number of students that chose baseball, we multiply 25% by 800 students surveyed. First we have to convert 25% to a decimal = 0.25
800 x 0.25 = 200 students chose baseball.
Then, for basketball, 20% of students chose that, so 20% = 0.20
800 x 0.2 = 160 students chose basketball
200-160 = 40 more students chose baseball than basketball
----------------------------
20. I don't know what your "magic sentence" looks like. You can set this up as a ratio, where x is the total number of flowers, and the 56% is a fraction of 56/100
280/x = 56/100
then cross multiply
28,000 = 56x
divide by 56
x = 500
Check the math: 500 x 0.56 = 280
If you want to tell me what your teacher's "magic sentence" looks like in the comments, I can try to fill it in with/for you.
Answer: The equation shall be
8 = 4W
Step-by-step explanation: The perimeter has been given as 46 feet, whereas the length and the width are not yet given. But the clue we have states that “the length is 19 feet longer than the width,” which means, if the width is W then the length shall be 19 plus W. We can express the dimensions as;
Length = 19 + W
Width = W
We can now express the perimeter as follows;
Perimeter = 2(L + W)
46 = 2(19 + W + W)
46 = 2(19 + 2W)
46 = 38 + 4W
Subtract 38 from both sides of the equation
8 = 4W
Answer:
Not possible
Step-by-step explanation:
The notation (f °g)(-2) means f(g(-2)). You will substitute -2 into g(x) then substitute the value or equation that results into f(x).
g(-2) = √x - 16 = √-2 - 16
This is not possible because the value of -2 cannot be found in a square root. Square roots do not compute real roots for negative numbers.
