We have that
(3√8)/(4√6)
we know that
√8---------> √(2³)-----> 2√2
so
(3√8)/(4√6)=(3*[2√2])/(4√6)---> 6√2/(4√6)
√6=√(2*3)---> √2*√3
6√2/(4√6)=6√2/(4√2*√3)----> 6/(4√3)----> 6/(4√3)*(√3/√3)-----> 6√3/(4*3)----> √3/2
the answer is
√3/2
Volume of the shampoo bottle
V = πr²h
Substituting,
V = π(2 in)²(7 in) = 87.9 in³ ≈ 88 in³
Volume of the suitcase,
Convert all dimensions to inches by multiplying by 12.
length = 36 in ; width = 24 in ; height = 12 in
Multiply the given dimensions,
V = (36 in)(24 in)(12 in) = 10,368 in³
Dividing the two calculated values will give us an answer of 117.82 or approximately 117 bottles.
The mistake done is described in letter A because as much as possible we want to overestimate the volume of the shampoo as its value becomes the divisor.
Answer:
the correct answer is A
Step-by-step explanation:
Answer:5/3 litres of paint is needed for 1 door.
Step-by-step explanation:
All the doors that Maren is painting are of the same size.
She used 3 liters of paint to cover 1 4/5 doors. Converting 1 4/5 into improper fraction, it becomes 9/5.
Let the number of litres of paint needed to paint 1 door would be x. Therefore
3 litres = 9/5 doors
x litres = 1 door
Crossmultiplying, it becomes
3 × 1 = x × 9/5
3 = 9x/5
9x = 3 × 5 = 15
x = 15/9 = 5/3 litres
R = d/2 = 10
common area = (2/3)πr^2 - (rt(3)/2)r^2
