G=number of words on george's page
b=number of words on bill's page
c=number of words on charlie's page
george has 2 times as many as bill's age
g=2b
bills contains 50 less than charlie
b=c-50
if each person can type 70 words per minute, after 1 minute (that is an additional 70 words for each person)
the difference between twice nmber of words on bill's page and the number of words on charlie's page is 220
so
that is after increase of 70 words
2(b+70)-(c+70)=220
and
b=c-50
subsittute
2(c-50+70)-(c+70)=220
2(c+20)-c-70=220
2c+40-c-70=220
c-30=220
c=250
charlie had 250 initially
b=c-50
b=250-50
b=200
bill had words 200 initially
who cares about george
Answer:
3
Step-by-step explanation:
15+ _ x 5
15 divided by 5 = 3
3 x 5= 15
C because The Prime Factorization is: 5 x 5, which is the same thing as 5^2.

Answer:
distance of diver 1 from the shark ≈ 18.88 m
Step-by-step explanation:
The illustration forms a triangle. The base of the triangle which is their distance apart is given as 30 m . The known angle of the triangle are 52° and 39°. To find the unknown side we subtract the sum of 52° and 39° from 180°. Note that the total angle in a triangle is 180°.
Therefore,
180 - (52 + 39) = 180 - 91 = 89
°. Now the three angle of the triangles are 52°, 39° and 89°.
Using the law of sine we can find the distance of the diver 1 from the shark.
let a = distance of the first diver to the shark.
a/sin 39° = 30/sin 89°
cross multiply
a sin 89° = 30 sin 39°
divide both sides by sin 89°
a = 30 sin 39°/sin 89°
a = 30 × 0.62932039105
/sin 89°
a = 18.8796117315
/0.99984769515
a = 18.8824876258
a ≈ 18.88 m
