hw: 3/2hrs = 3×30 = 90mins
chores: 1/2hr = 1×30 = 30mins
sleep: 17/2hrs = 17×30 = 510mins
90+30+510=630mins=10.5hrs/day
Answer:
Step-by-step explanation:
Since the shaded area is above the line and the line is solid, you will use the greater-than-or-equal-to sign.
Not to mention inequalities still have a slope and y-intercept. (In this case, the y-intercept will be -5, since the line crosses the y-axis at that point, and the slope will be -2 because the line is going down 2 units and to the right 1 unit.)
Hope this helps :)
add 12.7 on both sides. i chose the bigger number to get rid of negatives
-3.6b + 5.5 = 6.1b
get b by itself by adding 3.6b to both sides
5.5 = 9.7b
the answer would be 5.5/9.7 = b
you can simply if need 0.567=b
Answer:
The force on the book is 250N.
Step-by-step explanation:
Newton's second law states that the equation for the force is:
In which m is the mass, in kilograms, and a is the acceleration, in m/s². F is the force measured in N.
In this question:
So
The force on the book is 250N.
