Describe how to simplify the expression (3^-6)/(3^-4). Answers: Divide the bases and then add the exponents. Keep the base the same and then add the exponents. Multiply the bases and then subtract the exponents. Keep the base the same and then subtract the exponents.

Answer 1

Answer:

Answer:

Last option: Keep the base the same and then subtract the exponents.

Step-by-step explanation:

There is a property called "Quotient of power property".

This property states that if you need to divide two powers with the same base, you must keep the same base and subtract the exponents:

$(a^m)/(a^n)=a^((m-n))$

Then, you need to apply this property to the expression $((3^(-6)))/((3^(-4)))$ to simplify it.

Therefore, you get that the expression simplified is:

$3^((-6-(-4)))=3^((-6+4))=3^(-2)$

Trey read 10 pages in 25 minutes at at this rate how many pages will he read and 45 minutes

Answers

Trey will read 18 pages in 45 minutes.

This is because he read 2.5 pages a minute. 25/10 = 2.5
so if we 45/2.5 = 18

10 pages per 25 min. and now there is 45. Divide 45 by 25 and get 1.8, so not multiply 10 by 1.8 : 10 • 1.8 = 18. Trey reads 18 pages in 45 minutes. Hoped I helped!

Is 7 3/4 or 7 9/16 bigger

Answers

7 3/4 is bigger because when you multiply the numerator and denominator it is 7 12/16 and 12 is bigger then 9

7 and 3/4 is bigger.

The decimal for it would be 7.75
The decimal for 7 9/16 would be 7.5625

Each adult paid 75 cents and each student paid 50 cents at the schoot play. A total of 750 attended. How many adults attended if the receipts totaled $437.50?

Answers

Answer:

250 adults

Step-by-step explanation:

With the information of the problem we have a system of two linear equations:

$x+y=750$

$0.75x+0.50y=437.50$

Where x represent the quantity of adults and y represent the student. Solving the first equation for x we have:

$x+y=750\nx=750-y$

Using this result in the second equation:

$0.75x+0.50y=437.50\n0.75(750-y)+0.50y=437.50\n562.5-0.75y+0.50y=437.50\n-0.25y=437.50-562.5\n-0.25y=-125\n0.25y=125\ny=(125)/(0.25)\ny=500$

With this result we know that we have 500 students, using the result of y in the first equation we will find the answer for x then:

$x+y=750\nx+500=750\nx=750-500\nx=250$

Then the we have 250 adults.

You estimate that a baby pig weighs 20 pounds. The actual weight of the baby pig is 16 pounds. Find the percent error

Answers

Answer:

Percentage error is 25%.

Step-by-step explanation:

Given : Estimated weighs of a baby pig = 20 pounds

Actual weight of the baby pig = 16 pounds

To find : The percentage error

Solution : Formula to find percentage error

$\frac{\text{Estimated weight}- \text{Actual weight}}{\text{Actual weight}}* 100$

Putting values in formula,

$=(20-16)/(16)* 100$

$=(4)/(16)* 100$

$=(1)/(4)* 100$

$=25%$

Therefore, Percentage error is 25%.

Your estimate of the baby pig's weight is 2 pounds. However the actual weight of it is only 16 pounds.
Let's solve for the percentage error of this.
=> 20 - 16 = 4 pounds
=> 4 / 16 = 0.25
=> 0.25 * 100% = 25%
Thus, you added 25% of the baby pig's weight

An object moves backwards from where it starts 100 meters in 20 seconds. What is the velocity of the object? Select one:

5 m/s2

-5 m/s

5 m/s

- 5 m/s2

Answers

5m/s

The formula to find the velocity is distance/time.

So 100/20 is 5m/s.
It’s not 5m/s2 because this is the unit for acceleration.
And it’s not negative because it is not possible for the velocity to be negative.
