Answer:
Dave is 27. His brother is 18.
Step-by-step explanation:
Dave is 9 years older than his brother, so if his brother is 18, he is 27. If you doubled the brother's age (18) you would get 36. Then you subtract 36 by 9 and get 27. <3
Answer:
Nirmala can use the lamp for 31.66 hours before it runs out of oil.
Step-by-step explanation:
From the graph,
Take any two points, let say
(15, 25)
(25, 10)
The equation of line in slope-intercept form
Putting and any point, let say (25, 10), to find the y-intercept 'b'
So the equation of line will be:
In order to find how long Nirmala can use the lamp before it runs out of oil, we need to find x-intercept which can be obtained by putting y = 0, and solve for x, as duration lies on x-axis.
so
Putting y = 0
Therefore, Nirmala can use the lamp for 31.66 hours before it runs out of oil.
414.335 because of a calculator
Answer:
24
Step-by-step explanation:
1. First, let's find the common ratio between the sides we know.
2. The number 4 is the scale factor, so we multiply 6 by 4 to get the missing side length.
Therefore, the missing side length is 24.
Step-by-step explanation:
From the given table it is obvious that 162 is the largest number of the given numbers which corresponds to 45° angle.
So, he should kick the football at 45° angle for maximum distance.
