17. The variable "a" represents the age of the child
18. The variable "A" represents the adult dosage
19. The prescribed dosage of the medicine for the 6-year-old child is 60 milligrams.
Work: C=6/(6+12)·180
C=6/(18)·180
C=60
Answer:
40 mph
Step-by-step explanation:
If the speed increased by 20%, now the speed is 120% of the original speed.
48 mph is 120%, so dividing by 6 will get 8 which is 20%.
If 8 is 20%, you can multiply it by 5 to get 40, which is 100%. This means 40 mph is the original speed.
Hope this helps!
The volume of a cone is V=(1/3)(area of the base)(height)= (1/3)(pi*r^2)(h)
r^2= (d/2)^2 = (d^2)/4. Given: V= 301.44cm^3 and h= 18cm.
r^2= V/[(1/3)(pi)(h)]
r^2= 3V/(pi)(h)
(d^2)/4= 3(301.44)/(3.14)(18)
d^2= 12(301.44)/(3.14)(18)
d^2= 63.967
d= 7.997
d~= 8cm.
Answer:
Step-by-step explanation:
Mr Thomas earns 18.80 per hour for the first 40 hours of work in a week. This means that the total amount that he earned in the first
40 hours of work would be
40 × 18.8 = $752
He earns 1 and a half times and that amount per hour for each hour he works over 40 hours in a week. This amount per hour would be
1.5 × 18.8 = $28.2
Last week, Mr Thomas worked 45.5 hours. The extra hours that he worked is 45.5 - 40 = 5.5 hours.
Amount earned for 5.5 hours is
5.5 × 28.2 = $155.1
Total amount that Mr Thomas earned is
752 + 155.1 = $907.1
