Answer:
10 miles per 1/4 hour
40 miles per hour
Step-by-step explanation:
Given that:
A car travels 20 miles in 1/2 hour
Miles traveled per hour :
(20 * 2) / 1 = 40 miles per hour
Mile traveled in 1/4 hour :
Distance = speed * time
Distance = 40 mph * 1/4 = 10 miles per 1/4 hour
Car traveling 30 miles in 3/4 hours
(30 * 4) /3 = 120 / 3 = 40 miles per hour
Distance = 40 mph * 1/4 = 10 miles per 1/4 hour
Answer:
r - 12 = 74
Step-by-step explanation:
The difference between his height with 12 would signify subtraction with 12, and that difference is 74. Meaning, his height, minus 12, would equal 74.
3.60$ x (100%+10%)
=3.60$ x 110%
=3.60$ x 1.1
=3.96$ for a gallon of milk 5 years from now.
So if there are 8 bricks in a column, what we can say is, how many 8's will equal 32?
So basically,
8(?) = 32
And then if you divide both sides by 8, you get ? = 4.
So there are 4 bricks in each row.
Answer:
(negative infinity, 2)
Step-by-step explanation:
The two functions are given by f(x) = x - 3 and g(x) = - 0.5x
So, (f - g)(x) = x - 3 - ( - 0.5x) = 1.5x - 3
Then, for (f - g)(x) to be negative (1.5x - 3) < 0
⇒ 1.5x < 3
⇒ x < 2
Therefore, the interval will be (negative infinity, 2) for which the function (f - g)(x) will be negative. (Answer)
