Answer:
20 people
Step-by-step explanation:
Let x be the number of people initially. We can find the amount each of them has to pay at first
2 / x
But when 10 people walk away, the remaining (x - 10) has to pay 10 cents more to get the same total of $2. This would means
From here we can perform cross multiplication
Multiply both sides by 10x:
x = 20 or x = -10
Since x can only be positive we will pick x = 20
9514 1404 393
Answer:
(d) 25°
Step-by-step explanation:
Each diagonal represents a transversal between parallel lines. Alternate interior angles are congruent, so ...
∠BDC ≅ ∠DBA = 25°
So 70.52 and 13.27
so 13.27 is what percent of 70.52
percent means parts out of 100
what percent of 70.52
'of' can be tranlated to mutiply
13.27=x% times 70.52
13.27=x/100 times 70.52
13.27=70.52x/100
13.27=0.7052x
divide both side by 0.7052
18.82
the answer is 18.8%
the easy way is
to find percent assume 70.27=100
so x/100=
13.27/70.52 then multiply by 100=0.18817 multipliy 100
18.817=round 18.8%
answer is 18.8%
