Answer:
n = 6
Step-by-step explanation:
Two intersecting chords. The product of the parts of one chord is equal to the product of the parts of the other chord, that is
7(n + 4) = 5(n + 8) ← distribute parenthesis on both sides
7n + 28 = 5n + 40 ( subtract 5n from both sides )
2n + 28 = 40 ( subtract 28 from both sides )
2n = 12 ( divide both sides by 2 )
n = 6

Answer:
Diana approximately had 128 cards
Step-by-step explanation:
Let n be the number of cards Diana had. She knows that
- there are 17 kings among n cards
- 4 kings among 30 cards
Write a proportion:
Cross multiply:
Ok, angle C = 90
D = ? E = 32
Because angle E = 32 the angle inside the bigger triangle is the same size.
( They are the size because they have joint beginnings.)
So, 90 + 32 = 122
And, 180 - 122 = 58
Answer:
she ate 3/20 of the pie
Explanation:
lets say there are 10 slices.
if she ate 1 slice, then darryl ate 2, then Emily ate 3. That is only 5 total slices.
So what if she ate 2? Darryl ate 4, Emily ate 6. That still doesn't work
But if she ate 1.5 slices, then darryl ate 3, then Emily ate 5.5
1.5+5.5=7
7+3=10
so she ate 1.5 slices out of ten. But 1.5/10 cant be a fraction, so you can make it 15/100 and then simplify it 3/20. :)
