0.248 rounded to the nearest tenth is 0.2 because 4 comes after and if there is a number after the number that you are rounding that is less than 5, you keep the number and do not change it.
Answer:
A=1/2bh
A=1/2(2)(4)
A=1/2(8)
A=4
Step-by-step explanation:
Area is 4units²
Average speed for the entire trip, both ways, is
(Total distance) divided by (total time) .
We don't know the distance from his house to the gift store,
and we don't know how long it took him to get back.
We'll need to calculate these.
-- On the trip TO the store, it took him 50 minutes, at 6 mph.
-- 50 minutes is 5/6 of an hour.
-- Traveling at 6 mph for 5/6 of an hour, he covered 5 miles.
-- The gift store is 5 miles from his house.
-- The total trip both ways was 10 miles.
-- On the way BACK home from the store, he moved at 12 mph.
-- Going 5 miles at 12 mph, it takes (5/12 hour) = 25 minutes.
Now we have everything we need.
Distance:
Going: 5 miles
Returning: 5 miles
Total 10 miles
Time:
Going: 50 minutes
Returning: 25 minutes
Total: 75 minutes = 1.25 hours
Average speed for the whole trip =
(total distance) / (total time)
= (10 miles) / (1.25 hours)
= (10 / 1.25) miles/hours
= 8 miles per hour
Answer:
D = -1, -1, 2, 5
R = 0, 2, 3, 7
✅It is NOT A FUNCTION
Step-by-step explanation:
D (Domain) = input values (x-values)
D = -1, -1, 2, 5
R (Range) = output values
R = 0, 2, 3, 7
✅It is not a function because an x-value, -1, has two different y-values, 7 and 2, assigned to it.
Answer:
9 ft and 9 inches
Step-by-step explanation:
there are 12 inches in a foot
1ft = 12in
2ft = 24 in
3ft = 36 in
4ft = 48
and so on
9 ft = 108 inches which is the closes to 117.
So we have 9 ft
subtract 117 from 108, which is 9 inches left over
