How do we calculate 25% of 300
Natali5045456 [20]
25% is equal to \frac{1}{4}. To get 25% of 300, we multiply 300 by either 0.25 or \frac{1}{4}. This gives us (300)( \frac{1}{4}) =  \frac{300}{4}  =  \frac{150}{2} = 75

H(t)=2t-2 <br> g(t)=t-1 <br> find h(g(2))
Crazy boy [7]
T = 2

To find this, follow these steps.

First, you need to find g(2):

t-1
2-1
1

Therefore 1 is your first answer. Then you input that answer into h(t).

2(t) - 2
2(2) - 2
4 - 2
2

Thus, 2 is your final answer.

A 5-gallon bucket is full of pure water. Suppose we begin dumping salt into the bucket at a rate of 1/4 pounds per minute. Also,
Tatiana [17]

Answer and explanation:

1. In one minute, there would be zero pounds of salt in the bucket because there's 0.25 pounds of salt in one minute and 0.5 gallons of water leaves the bucket in same minute, eliminating the 0.25 pounds of salt.

2. In ten minutes there would be zero pounds of salt because theres 0.25×10= 2.5 pounds of salt and 0.5×10=5 gallons of water would leave the bucket, eliminating the salt.

3. In 60 minutes there would still be zero salt because water leaves the bucket more than salt enters

4. Zero salt too after bucket leaks

5. Zero salt

What is 7/2 divided by 49/4?
ruslelena [56]

Answer:

\frac{2}{7}

Step-by-step explanation:

\frac{7}{2} ÷ \frac{49}{4} needs to be flipped and multiplied.

It will become \frac{7}{2} · \frac{4}{49}.

Simplify the fractions by replacing 7 with 1 and 49 with 7, since 7 is 1/7 of 49. Then, turn the 2 into a 1 and the 4 into a 2, since 2 is half of 4.

You will be left with 1 · \frac{2}{7}, which equals \frac{2}{7}
