You need to draw the triangle DEF with a right angle at E. Angle D = 40 and DE = 100 m. Once you have marked up your triangle, you can use cosine to find DF.
1: ----> 2:00
2: ----> 4:45
3: -----> 2:15
4: -----> 4:41
5: -----> 16:15
Since 8 students take both, that leaves only 4 students who take Algebra I alone.
Likewise since 8 students take both, that leaves 10 who only take Algebra 2
So out of the 60, twenty two are taking either Alg I Alg Ii or both.
That leaves 38 people who are not taking either.
b. 38
You can set this up using a 2 circle venn diagram. Just be sure to put the 8 who take both in first.
Answer:x=3
Step-by-step explanation:
-5x=-15
divide by -5
x=3
Answer:
L: 110 W: 90
Step-by-step explanation:
110 + 110 + 90 + 90=400 (perimeter)
110 x 90 =9900 (new area that is greater than the original)
ding ding.
also this was not worth only five pts man LOL
