Answer:
32%
Step-by-step explanation:
50% of the first solution is HCL, so it has
80 ml x 50% = 80 ml x 0.5 = 40 ml of HCL
Similarly the second solution has 20% of HCL, so
120 ml x 20% = 120 ml x 0.2 = 24 ml of HCL
The combined solution will have 40 ml + 24 ml = 64 ml of HCL.
The total volume of the 2 solutions is 80 ml + 120 ml = 200 ml.
We can now calculate the concentration of HCL in the mixed solution, by dividing the volume of HCL by the total volume of the solution,
64 ml / 200 ml = 0.32 = 32%

The graph of a function f is given use the graph to estimate all the local maximum and minimum values as a function and the value of x at which each occurs then the intervals the function is increasing and the function is decreasing I figured out the increasing is negative 9 and 0 and 6 and infinity
Answer:
The function f is graphed.
f is an even function as it has U- form.
As per the graph there is one local maximum at (0, 4) and one local minimum at (6, 1).
The global minimum is (-9, -2) and the global maximum is infinity.
The minimum and maximums are the borders of the increasing or decreasing intervals.
Intervals when the function is increasing:
(-9, 0] and [6, +∞)Intervals when the function is decreasing:

Answer:
$104.56
Step-by-step explanation:
The computation of the cost of the road trip as follows:
The total number of gallons required is
= 568 ÷ 21 miles
= 27.05 gallons.
Now
the cost of one gallon is
= 3.79 × 1.02
= $3.8658
So, the cost of the road trip is
= 27.05 × 3.8658
= $104.56

Answer:
13 hours at Job B, and 17 hours at Job A.
Step-by-step explanation:
13×7.20= 93.60
17×5.90=100.30
100.30+93.60= 193.90

Step-by-step explanation:
It depends.
If x and y are Whole Numbers, it would be 14<y+x<31.
If x and y are Real Numbers, including decimals and fractions, it would be 13<y+x<32
Since it doesn’t specify, it’s probably the latter.

Find the cos of angle T....
Answer:
C = 24/25
Step-by-step explanation:
Recall, CAH.
Thus:
Cos T = adjacent/hypotenuse
Reference angle = T
Adjacent = 24
Hypotenuse = 25
Therefore,
Cos T = 24/25
Sonya makes a pattern of values for x and a pattern of values for y. Which
ordered pair continues the patterns and has an x-value of 6?
Answer: (6, 9)
Step-by-step explanation:
We have the pairs:
x y
0 0
2 3
4 6
These can be written as points (0, 0), (2, 3) and (4, 6)
This seems to be a linear relationship:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
In the cases where the point (0, 0) belongs to the graph, we have a proportional relationship, which is written as:
y = k*x
In this case we have that point, then this is a proportional relationship.
Now we could just replace the values of one of the points (not the (0,0) point) in the equation in order to find the value of x.
If we use the point (2, 3) we get:
y = 3
x = 2
then:
3 = k*2
3/2 = k
Then the relationship is:
y = (3/2)*x
Now we want to know the ordered pair such that x = 6, then we just eed to replace x by 6 in the above equation:
y = (3/2)*6 = 9
Then we have x = 6 and y = 9
The correct option is (6, 9)

if i walk 120 meters per minute slower than i cycle. my cycling speed is 3 times faster than my walking. What is my walking speed. meters per minute
Answer:
His walking speed is 60 meters per minute.
Step-by-step explanation:
Given that the person walks 120 meters per minute slower than he cycles, and his cycling speed is 3 times faster than his walking, in order to known his walking speed in meter per minute, the following logical reasoning has to be made:
The person walks 120 meters per minute slower than he rides a bicycle, and in turn, rides a bicycle three times faster than he walks. Therefore, those 120 meters per minute is 2/3 of his speed on a bicycle, which makes up the remaining third with the speed at which he walks. Thus, since 120/2 is 60, and 60 x 3 is 180, the person walks at 60 meters per minute, and bicycles at 180 meters per minute.
