7. Solve. 4(s – 3) = 2s + 6
Answer:
s=9
B twice the force with which it was fired.
C one half the force with which it was fired.
D the same amount of force with which it was fired.
E one quarter the force with which it was fired.
Answer:
A zero, since no force is necessary to keep it moving
Step-by-step explanation:
Since, the space is friction less, the force exerted by the gun will be enough to keep the ball going. There will not be any depreciation in the initial force. Hence, the ball continues to move forward without any impediment.
Hence, the correct answer is
A zero, since no force is necessary to keep it moving
Answer:
y = 7
Step-by-step explanation:
0.3y+0.6 = 9.7 - y
0.3y+y = 9.7 -0.6
1.3y = 9.1
y= 7
sorry it had an error
Answer:
y = 5x + 20
Step-by-step explanation:
Answer:
Y=5x+20
Because 20 is a fee that is in constant value and shouldn't be correlated with the amount of months using the subscription. 5 is the amount charged every month you keep the subscription. Y is outcome of cost, and x is the amount of months.
Answer:
Options B,C and E are correct choices.
Step-by-step explanation:
We are asked to find correct answers for the given box and whisker plots.
Let us our options one by one.
A. This option is false as lowest value for children's cereals is 30 and highest value for adults is 35.
B. This option is correct. We can see our upper value for combined range will be 60 and lower value will be 5 and range is upper value- lower value.
C. Since we know that we can find spread of data by its range.
So option C is correct indeed.
D. This options is false because for adults mean and median are different while for children mean and median are same.
E. We can see that median for children's cereals is 45 and it is about 12 for adults.
We can see that . So median amount of sugar in children's cereals is 3 times as much as the median amount of sugar in adult's cereals.
Therefore, options B,C and E are correct choices.
A. 746
B. 608
C. 365
D. 296
