Two thousand nine hundred twenty-nine and eight hundred seventy-four thousandths
Answer:
Part a) 2.36 quarts
Part b) 47.2%
Step-by-step explanation:
Let
x ---> percentage of the resulting mixture that is antifreeze
Remember that
we know that
3 quarts of a solution multiplied by 0.22 (percentage in decimal form) plus 2 quarts of a solution multiplied by 0.85 (percentage in decimal form), must be equal to 5 quarts of a solution multiplied by x (percentage of the resulting mixture)
so
The linear equation that represent this situation is
solve for x
Convert to percentage
therefore
The percentage of the resulting mixture that is antifreeze is 47.2%
To find out how many quarts of antifreeze are in the resulting mixture, multiply the total quarts of the resulting mixture by the percentage in decimal form
Answer:
The choice that matches the graph of the function as is defined to us is:
Graph A.
Step-by-step explanation:
We are given a function f(x) as:
f(x)= 2x if x < 3
and 4 if x ≥ 3
This means that in the region (-∞,3) the graph of a function is a straight line that passes through the origin and has a open circle at x=3.
and in the region [3,∞) the graph is a straight horizontal line i.e. y=4.
Hence, the graph of this function is:
Graph A.
I think 300 kelvins is greater
To get the ratio we have to put into numerator number of girls and into denominator number of boys. Then simplify it
It also can be denoted as 4:5
