Answer:
2 1/4 cups of bleach
Step-by-step explanation:
4.5/10=0.45
0.45×5=2.25
Answer:
Problems like this all have the same solution method.
If you have n letters, you start with n!. Then you divide by k! for each distinct set of k letters.
This is purely mechanical. E.g., if you have
AAAAABBBBCCC
DEFGHIJKLMNOP
there are 25 letters, and groups of 5 4 and 3
The answer is 25! / (5! 4! 3!). See, all you need to do is count the letters and then count how many times any letters are repeated. Then you can just write down the answer.
Once you know that, these problems are really, really easy.

The distance of the ball from the foot of the tower is : 35.18m
The ball would be moved 57.2m away from the foot of the tower for the Angle of elevation to be halved.
<h3>What is angle of elevation?</h3>
Angle of elevation is the angle formed between the horizontal and the line of view from the vertical.
Analysis:
The height of the tower and the distance of the ball from the foot of the tower form a right angle triangle.
so we use trigonometry.
a) let distance of the ball from foot of tower be x.
so that, tan 52 = 45/x
x = 45/tan52
x = 45/1.279 = 35.18m
b) let the distance of the ball in the new position from the foot of the tower be y.
if the angle of elevation is halved, then new angle is 52/2 = 26°
tan 26 = 45/y
y = 45/tan26 = 45/0.487 = 92.4m
distance moved from old position to new position = 92.4 - 35.18 = 57.2m
In conclusion, the distance of the ball from the foot of the tower and the distance the ball should move to make its elevation 26° are 35.18m and 57.2m respectively.

Answer: the excess skin is surgically removed
Step-by-step explanation:
This problem can be solved with a proportion. We know that 8% of the population is the 368,000 and we want to find the whole population.
To make the proportion, let P be the population. Left side of the equals is the group we know, right side is the whole state, the top is the portions, the bottom are the populations.
We can't have percents in the proportions, so let's convert them to fractions or decimals. Percent means "per 100". So 8% = 8 per 100 = 8 / 100 = 0.08 Similarly, 100% = 100 per 100 = 100/100 = 1
Now we cross multiply to solve.
(0.08)(P) = (1)(368000)
0.08P = 368000
P = 368000/0.08 <-- divide both sides by 0.08
P = 4600000
Thus, Indiana has a population (that's aged 5 years or older) of 4,600,000.
