Answer: 3.66 pints of blue paint.
Step-by-step explanation:
She used 2/5 of the total number of pints to paint white.
That number in pints is:
= 2/5 * 6.1
= 2.44 pints of white
The number of pints used to paint blue is therefore:
= 6.1 - 2.44
= 3.66 pints of blue paint.
Counting in 10s is faster than counting in ones because counting in 10s gets you to larger numbers faster because you are going by larger numbers.
Answer:
If the exam has 10 questions, the probability will be 0,0078
Step-by-step explanation:
To get the probability equally likely of having the question right we use the following formula
P=# of possibilities that meet the condition / #of equally likely possibilities.
Each question has the following probability of being right.
P=1/2
In this case, we considered 10 questions as the total exam. So, we have to get 7 questions right to pass the exam (70%).
To get the probability of several independent events occurring together, we just multiply the probability of the all the events.
P(passing the exam)=1/2*1/2*1/2*1/2*1/2*1/2*1/2=0,0078
Answer:
8 cylinders
Step-by-step explanation:
The surface area of a cylinder is given by the formula ...
A = 2πr(r +l) . . . . . for radius r and length l
__
The cylinders Rufus has each have an area of ...
A = 2π(5 cm)(5 cm +4 cm) = 90π cm² ≈ 282.74 cm²
That means 2500 cm² of paint will cover ...
2500 cm²/(282.74 cm²/cylinder) ≈ 8.84 cylinders
Rufus has enough paint to cover 8 cylinders completely.
