Write 93/50 as a percentage.
elena55 [62]
Answer: 186%

To get this simply divide 93 into 50 (you will get 1.86 which you can convert to the percentage 186%). An even easier way is to multiply 93 by two (186) since 50% times 2 is 100%. Hope this helps!

A bowling alley has a fixed base cost and charges a variable per game rate. It costs $20.50 for five games and 28.50 for nine ga
lbvjy [14]


As ordered pairs ( g , C ) where g is the number of games and C is the cost

( 5, 20.50) and ( 9, 28.50)

the slope M = ( 28.50 - 20.50 ) / (9-5)

= 8/4

= 2

So the slope M=$2 per game

Using (5, 20.50)
The intercept B = y - m* g
= 20.50 - 2 * 5
= 20.50 - 10
= 10.50

So the fixed base cost, or FLAT RATE is $10.50.
That is if they played ZER0 games, they still have
to pay $10.50 just to get in.

The linear function is C (g) = 2*g + 10.50

Two cruise ships depart from the same harbor. SeabournOdysseydeparts at 8 AM, and travels due south2 mph faster than the northbo
yan [13]

The traveling speed of each ship is :

  • Ship A = 24 mph
  • Ship A = 24 mphShip B = 26 mph

Distance apart at 12:00 noon = 176 miles

Recall :

Distance = speed × time

Ship A :

Departure time = 9AM

Speed = s

Travel time = 12 - 9 = 3 hrs

Distance covered = 3 × s = 3s

Ship B :

Departure time = 8AM

Speed = 2+s

Travel time = 12 - 8 = 4 hours

Distance = 2+s(4) = 8 + 4s

Distance apart = 3s + (8 + 4s)

176 = 3s + 8 + 4s

176 = 7s + 8

176 - 8 = 7s

168 = 7s

s = 168 / 7

s = 24

Ship A speed = s = 24mph

Ship B speed = s + 2 = 26 mph
