Answer:
1. 180
2. 300
3. 480
Step-by-step explanation:
1. Since 30% of 600 (or 0.3 * 600) = 180, the 1st blank is 180.
2. 50% of 600 (also easy to just think of one half {1/2}) = 300
3. Because 180 + 300 = 480
hope this helps:)
640 divided by 5 is 128, therefore it’s 128 calories
In the case that you presented, the ratio is
50/100 = (x1)^2 / (x2)^2
1/2 = (x1)^2 / (x2)^2
x1 : x2 = 1 : √2
^2 means squared
Answer:
5.5
Step-by-step explanation:
y = 0.5x + 5
Use the slope-intercept form to find the slope and y-intercept.
Slope: 0.5
y-intercept: 5
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding values.
To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y.
y = 0.5(0) + 5
y = 5
To graph the y intercept using the equation of the line, plug in 1 for the x variable and solve for y.
y = 0.5(1) + 5
y = 5.5
Which means when x is 0, y intercept at 5 and when x is 1 y intercept at 5.5. Graph the line using the slope and the y-intercept, or the points.
This tells us, in practical terms, that, for every one unit that the x-variable increases (that is, moves over to the right), the y-variable increases (that is, goes up) by 50% of a unit.
Answer:
The answer is B
Step-by-step explanation:
2x+2y =10 and y= -x +5
These are not in the same form so thats the first step
2x+2y=10
we minus 2x from both side which turns into
2y=-2x+10 (the variable always comes first)
Secon step is to divide 2 from the y to everything so 2y divided by 2 = y
-2 divided by 2 is -x and 2 divided by 10 is 5 and now you have the same equations which leads to infinite
y=-x+5
