Answer: Comment: From the explanations below,
2x + y = 10
-6x = 3y + 7 had an infinite solution, while y = 14 -2x
6x + 3y = 42 has a fictitious solution, so also equation
2x + y = 17
-6x = 3y - 51.
Step-by-step explanation:
A one to one function is a function which matches <em>exactly one </em>x value with <em>exactly one </em>y value. The fancy term for this is an <em>injective function</em>.
Answer:
C) 60.
Step-by-step explanation:
Okay, I do math a little bit different than other kids... No worries though, its still correct.
First, find out how many times five can be put into a hundred. You should have gotten 20.
Now, we can use the twenty we got. Multiply 20 by the ratio of the boys. So 20 * 3 = 60.
Girls would be
20 * 2 = 40.
Those two numbers add up to a hundred so its all good. ^-^
Hope I helped!!
Answer: 8
Step-by-step explanation:
we know the area of a circle is
A=π r²
50.24= 3.14* r²
50.24/3.14=r^2
16=r^2
r=sqrt 16=4
diameter is 2r=2*4=8
Mean is the average. To find the average of any set of numbers, you add up the numbers and divide that sum by the number of numbers you added. Here when you add the numbers together you get 365. Because there were 10 numbers there, divide 365 by 10 to get 36.5, or B
