Answer:

1) ven diagram #1

2)160

3) 420

4)16

Step-by-step explanation:

1) lets make a ratio table:

(look at image below, sorry for the horrible writing)

the original ratios are 18 and 17, and 18+17=35 35 is the number of students who play either or both sports. 30 is the number who play either sport:

so 35-30=5

5 students play both sports:

18-5=13(baseball)

17-5=12(basketball)

2) add up all the students who do band or sports and subtract from the total number of students

89/464+215/464= 304/464 students play in band or orchestra or both, to find the number of students who dont:

464-304=160

3) 630/1000+420/1000=1050/1000

1050/1000-210/1000=840/1000

840/1000-420/100=420/1000

420 ppl use brand p

4) 15+9=24

40-24=16

16 ppl

hope this helps!

In the diagram below, GH is parallel to DE . If GH is 3 more than EH FH=10, and DE=12 find the length of EH. Figures are not nec

Answer: 5

Step-by-step explanation:

Since $\overline{GH} \parallel \overline{DE}$ , by the corresponding angles theorem, $\angle FGH \cong \angle FDE, \angle FHG \cong \angle FED$ . This means $\triangle FGH \sim \triangle FDE$ by AA.

As corresponding sides of similar triangles are proportional,

$\frac{10}{x+3}=\frac{10+x}{12}\\(10)(12)=(10+x)(x+3)\\120=x^{2}+13x+30\\x^{2}+13x-90=0\\(x+18)(x-5)=0\\x=-18, 5$
However, as distance must be positive, we consider the positive solution, x=5.
