Answer: the answer would be 24 = m
Step-by-step explanation:
I got that answer be dividing both 2.5 and 15 and figured out that 1 hour equals 6 mile so that would make it so that it is 24
In mathematical expression, the equation then becomes 7 - 2n = 5
The next procedure is to find the unknown.
1. 7 - 2n = 5
2. -2n = 5 - 7
3. -2n = -2
4. n = -2/-2
5. n = 1
Check:
Substitute n = 1
7 - 2 (1) = 5
7-2 = 5
5=5
60 seconds = 1 minute
60/15 = 4
12 hops in 15 seconds is the same as
4 * 12 hops in 4 * 15 seconds, or
48 hops in 60 seconds, and since 60 sec = 1 min, it equals
48 hops per minute.
Answer:
The measure of ∠D = (Q) = 28.81
Step-by-step explanation:
Tan(Q) = perpendicular/ base
In this case perpendicular is BC and base is DC
BC =25 DC = 45
Tan(Q) = BC/DC
Tan(Q) = 25/ 45
Tan(Q) = 5/ 9
(Q) = tan^ -1 (0.55)
(Q) = 28.81
