use the distributive property
Answer: each guest gets 4.19 cm²
Step-by-step explanation:
The cake is a circle. The area which he cuts for himself is a sector with a central angle of 120 degrees. The formula for determining the area of a sector is expressed as
Area of sector = θ/360 × πr²
Where
θ represents the central angle
π is a constant whose value is 3.14
r represents the radius of the circle.
From the diagram,
r = 4cm
Therefore, area of the cake that he cut for himself is
120/360 × 3.14 × 4²
= 16.75 cm²
The total area of the cake is
3.14 × 4² = 50.24 cm²
Therefore, the rest of the cake is
50.24 - 16.75 = 33.49 cm²
The amount that each guest gets would be
33.49/8 = 4.19 cm²
Answer:
Step-by-step explanation:
eq. of line parallel to AB is y=2x+a
if it passes through (3,-2) then
-2=2×3+a
a=-2-6=-8
y=2x-8
use this formula Sn=n/2[2a+(n-1)d]
here,d=a2-a1 and n= no. Of terms
Step-by-step explanation:
S8=8/2[2(1)+(8-1)2]
S8=64
The human body has about 5.5 liters of blood
3 deciliters is about 0.3 liters
so 5.5/0.3=18.33333
so she could fill 18 and 1/3 glasses before she died
wait
oooooh, she has a supply of blood other than her own, nvm, I should read better
1 decileter is 1/10 of a liter
so 3/10 of a liter per glass
6 of those 2 liter bottles
so total is 6*2=12 liters
so
3/10 times number of glasses=12
times both sides by 10/3
number of glasses=120/3
number of glasses=40
can fill 40 glasses with the blood she is supplied (not including her own)
