Answer:
25
Step-by-step explanation:
The median of a trapezoid equals one half of the sum of the bases
AC is a median and EB and DF are the bases.
hence AC = 1/2(EB + DF)
We are given that EB = 13 and that AC = 19. And we need to find DF
To do so we plug in what we are given and solve for DF
AC = 1/2(EB + DF)
AC = 19, EB = 13
19 = 1/2(13 + DF)
Now solve for DF
* Multiply both sides by 2*
19 * 2 = 38
1/2(13 + DF) * 2 ( the 1/2 and 2 cancel out and we're left with 13 + DF )
We then have 38 = 13 + DF
* Subtract 13 from both sides *
38 - 13 = 13 - 13 + DF
We get that DF = 25
You need 20 oz. of punch with 3 parts ginger ale and 2 parts HI-C. So the end result will have 5 parts. To find out how many ounces are in each part, just divide the total (20) by the number of parts (5):
20 / 5 = 4
There will be 4 ounces per part.
First, solve for the amount of ginger ale. The problem says the punch is 3 parts ginger ale, so just multiply the number of parts by the amount in each part:
(3)(4) = 12
The punch will have 12 ounces of ginger ale.
Next, solve for the amount of HI-C. The problem says the punch is 2 parts HI-C, so just multiply the number of parts by the amount in each part:
(2)(4) = 8
The punch will have 8 ounces of HI-C.
Hope this helps!
Answer:
10 m / minute
Step-by-step explanation:
Starting position = North ; back to North gives a Displacement of 0 ; the from that position to 900 m south gives a final Displacement of 900
Displacement / time
Displacement = 900
Time = 9 minutes
900 / 9
= 10 m / minute
