9 buses of students, teachers and parents went on a field trip. if 5 of the buses held 63 people each and other buses held 54 people each how many people went in all

The swimming pool will contain 482 gallons of water after 6 hours.

To find out how many gallons of water the pool will contain after 6 hours, we can use the formula: Volume = initial volume + rate of change * time. In this case, the initial volume is 500 gallons, the rate of change is -3 gallons per hour, and the time is 6 hours.

Using the formula, we have: Volume = 500 + (-3 * 6) = 500 - 18 = 482 gallons.

Therefore, the pool will contain 482 gallons of water after 6 hours.

Answer:

3,5,6,7,9

These are the answers

Answer:

Option D.

Step-by-step explanation:

The given expression is [tex](5.5\times 10^{-6})-(3.7\times 10^{-7} )[/tex]

We have to write it in the simplified form.

[tex](5.5\times 10^{-6})-(3.7\times 10^{-7} )[/tex]

= [tex](5.5\times 10^{-6})-(0.37\times 10^{-6} )[/tex]

= (5.5 - 0.37)×[tex]10^{-6}[/tex]

= 5.13×[tex]10^{-6}[/tex]

Option D will be the answer.

Answer:

[tex]\frac{1}{2^{10}}=2^{-10}[/tex]

Step-by-step explanation:

[tex]\frac{1}{1024}[/tex]

To get the expression with negative exponent , we need to convert the number 1024 in exponential form

[tex]1024= 2^5 \cdot 2^5= 2^{10}[/tex]

Replace the denominator by 2^10

[tex]\frac{1}{2^{10}}[/tex]

Now we apply exponential property

[tex]\frac{1}{a^m} =a^{-m}[/tex]

[tex]\frac{1}{2^{10}}=2^{-10}[/tex]

negative exponent other than -1 is [tex]\frac{1}{2^{10}}=2^{-10}[/tex]

The annual interest rate is 6% and this can be determined by using the formula of simple interest and also by using the given data.

Given :

The formula of the simple interest can be used in order to determine the annual interest rate.

The formula of the simple interest is given by:

A = P(1 + rt)

where A is the final amount, P is the principal amount, r is the rate of interest, and t is the time in years.

Now, substitute the values of the known terms in the above formula.

520 + 156 = 520(1 + 5r)

Simplify the above expression in order to determine the value of 'r'.

676 = 520(1 + 5r)

1.3 = (1 + 5r)

0.3 = 5r

r = 0.06

Now, multiply by 100 in order to determine the percentage.

r = 0.06 [tex]\times[/tex] 100

r = 6%

So, the annual interest rate is 6%.

The  Statement 3: "There are exactly 30 more girls than boys". is absolutely true.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

The ratio of the number of boys to the number of girls at Liam's school is 4:5 and there are 270 students at his school.

4x + 5x = 270

9x = 270

x= 30

Then, Total boys = 4(30) = 120

Total girls = 5(30) = 150

We can see that Clearly, (Number of girls) > (Number of boys)

Difference =  (Total girls) - (Total boys)

= 150-120

= 30

Hence, The  Statement 3: "There are exactly 30 more girls than boys". is absolutely true.

Answer:

[tex]\frac{5}{6}[/tex] pound of turkey you purchase for 10 dollars

Step-by-step explanation:

Unit rate defined as the rates are expressed as a quantity 1 such as 3 meter per second or 4 miles per hour.

As per the statement:

If you can buy 1⁄3 of a pound of turkey for 4 dollars

by definition of unit rate we have;

[tex]\text{Unit rate per dollars} = \frac{\frac{1}{3} }{4} = \frac{1}{12}[/tex] pound of turkey.

We have to find how much can you purchase for 10 dollars.

[tex]\text{Weight of turkey for 10 dollars} = \text{Unit rate per dollars} \times 10[/tex]

⇒[tex]\text{Weight of turkey for 10 dollars}=\frac{1}{12} \times 10 = \frac{5}{6}[/tex] pound

Therefore, [tex]\frac{5}{6}[/tex] pound of turkey you purchase for 10 dollars
