A veterinarian uses weights in kilograms to figure out what dosages of medicines to prescribe for animals. For every 10 kilograms, there are 22 pounds.
1. Calculate each animal’s weight in kilograms. Explain or show your reasoning. If you get stuck, consider drawing a double number line or table.
a) Fido the Labrador weighs 88 pounds.
b) Spot the Beagle weighs 33 pounds.
c) Bella the Chihuahua weighs 5 1/2 pounds.
2. A certain medication says it can only be given to animals over 25 kilograms. How much is this in pounds?

The answer is in the image 

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

The answer is in the image 

tip=18% of 75.45

     =18/100 * 75.45 = $13.581

Tip = $13.581

Volume of rectangular prism=length * width * height

Given,

length=3/8cm

breadth=5/8cm

height=7/8cm

therefore volume=(3/8)*(5/8)*(7/8)

                           =105/512 cm3

The solution is given below

The answer is in the image 

Cost of 6 gallons =$15

Cost of 1 gallon =15/6

                           =$2.5

Cost of 7 gallons=$2.5 * 7

                           =$17.5

Different mustangs that can be created are = 5 * 3 * 2

                                                                      = 30

30 different mustangs can be created

Given eq k = 10t-19

Given t = -7

k = 10*(-7) - 19

  = -70 -19

   =-89
