Hoi..
1/6 gallon all u need to do is divide
I assume the sentences:
"23 employees speak German; 29 speak French; 33 speak Spanish"
mean these speak ONLY the respective languages other than English.
Then the calculations boil down to those who speak ONLY two languages, noting that 8 speak French, German and Spanish, which need to be subtracted from
1. French and Spanish: 43-8=35 (speak only two foreign languages)
2. German and French: 38-8=30 (speak only two foreign languages)
3. German and Spanish: 48-8=40 (speak only two foreign languages).
Now We add up the total number of employees:
zero foreign language = 7
one foreign language = 23+29+33=85
two foreign languages = 30+35+40=105
three foreign languages=8
Total =7+85+105+8=205
(a) Percentage of employees who speak at least one foreign lanugage = (85+105+8)/205=198/205=.966=96.6%
(b) Percentage of employees who speak at least two foreign lanugages = (105+8)/205=113/205=.551=55.1%
Answer: 3
1/4 of an hour is equal to 15 minutes
15 / 5 = 3 - five minute segments
The sum of the angles of 4-sided shapes is 360°
To find the missing angle, you can do this:
x + 92° + 47° + 82° = 360° Add 92, 47, and 82 together
x + 221° = 360° Subtract 221 on both sides to get "x" by itself
x + 221° - 221° = 360° - 221°
x = 139° Your answer is the 4th option
