Answer:
Sian would receive 20 Pounds while Abigail would receive 10 Pounds.
Step-by-step explanation:
Given that Sian is twice as old as her sister Abigail, it means that if Abigail's age is T years then Sian's age would be 2T years.
If they divide 30 pounds in the ratio of their ages, the ratio of their ages will be
T : 2T (Ratio of Abigail's gae to Sian's age)
The amount received by Abigail
= T/(T + 2T) × 30
= T/3T × 30
= 1/3 × 30
= 10 Pounds
The amount received by Sian
= 2T/(T + 2T) × 30
= 2T/3T × 30
= 2/3 × 30
= 20 Pounds
The height of the pyramid is 45 feet.
Using the formula
v= volumn
a= base area
h=height
V=A x h/3
Solving for h
h=3V
A=3X600/40=45ft
To find height, First, square the base area to find the bottom area. Then, divide the known extent by way of the bottom location. finally, multiply the obtained quotient with the height of three to get the pyramid height.
The peak of a rectangular-primarily based pyramid the usage of your expertise of algebra. H = V / (L x W) / three
