If there are 40 children aged twelve and under and x of them are under three years old, 40 - x aged three twelve years old. From the 92 people that where taken by the company on whale watching trips, 52 are over twelve years old. The equation that best show the total cost, C is
                                (40 - x)(36) + (52)(48) = C
Rearranging the equation gives,
                                       x = 40 - ((C - 2496)/ 36)

The perimeter of the rectangle below is 114 units. Find the length of side PQ.
Anna35 [415]

Answer:

PQ=36

Step-by-step explanation:

o=114

PQ I named a because it was easier for me and SP I named b.

o=2(a+b)

114=2(3x+3+2x-1)

114=6x+6+4x-2

114=10x+4

10x=114-4

10x=110/:10

x=11

a=3*11+3

a=33+3

a=36

Barry's family drove 843 miles to see his grandparents. On the first day, they drove 483 mi. On the second day, how long did it
IrinaVladis [17]

Answer:

on the second day it took them 6 hours to get to their grandparents' house

Step-by-step explanation:

First we have to calculate how many miles they had to drive the second day

For this we have to subtract from the total miles the number of miles they drove the first day

843 mi - 483 mi = 360 mi

To calculate the time it takes we have to divide the distance it has to travel by the average velocity at which they travel

v = 60 mi/h

d = 360 mi

t = d/v

t = 360(mi) / 60(mi/h)

t = 6 h

on the second day it took them 6 hours to get to their grandparents' house

Celine has a bottle that contains 20% of milk and the rest water. The bottle has 1 liter of water. Part A: Write an equation in
Alexxx [7]
Percentage of milk PM
Liters of milk LM
Liters of water W
Total number of liters TL
W/100*PM = LM
W+LM =TL

Proof
1 liter / 100 = 10 milliliters
10 ml * 20 = 200 milliliters
200 ml + 1000 ml = 1200 ml
1.2 liters is the total amount of liters.
