2. negative ten raised to the fourth power divided by four raised to the tenth power)
3. four raised to the third power divided by ten raised to the fourth power)
4. negative four raised to the third power divided by ten raised to the fourth power)

Answers

Answer 1

The expression that is equivalent to the given expression (10^−2 • 4^5)^−2 is 10^(4) • 4^(−10)

How to determine the expression that is equivalent to the given expression?

The expression is given as

(10−2 • 45)−2

Rewrite the above expression properly as follows:

(10^−2 • 4^5)^−2

Apply the power rule of indices

So, we have

(10^−2 • 4^5)^−2 = 10^(−2 * −2) • 4^(−2 * 5)

Evaluate the product of powers

So, we have

(10^−2 • 4^5)^−2 = 10^(4) • 4^(−10)

Hence, the expression that is equivalent to the given expression (10^−2 • 4^5)^−2 is 10^(4) • 4^(−10)

What is the scale factor that was used to create WH

Answers

Answer:

The scale factor is 4/3

Step-by-step explanation:

Let x = the scale factor

15x = 20  Divide both sides by 15

x =20/15  Which simplifies to 4/3

The scale factor that was used to create WH will be 4/3.

What is the scale factor?

The scale factor is defined as the proportion of the new image's size to that of the previous image decision-making. Dilation is the process of increasing the size of an object while maintaining its shape. Depending on the scale factor, the object's size can be increased or decreased.

Given that BF is dilated to create WH. The center of dilation is point A where BF=15, WH=20

The scale factor will be calculated as below:-

Let x = the scale factor

15x = 20  

Divide both sides by 15

x =20/15  

Which simplifies to 4/3.

x = 4 / 3

Therefore, the scale factor that was used to create WH will be 4/3.

Step-by-step explanation:

Students were asked how they travel to
school. 37% of the students said they
travel by train.
Of these, 24% live more than seven miles
from their school. What percentage of the
students travel over seven miles to school
by train? Give your answer to 2 d.p.

Answers

the percentage of the students travel over seven miles to school by train is 9 %.

Let the total number of students be represented by variable x

now, 37 % of them travel by train.

So, we get that:

By train = 37 % of x

By train = 37 / 100 (x)

By train = 0.37 x

Now, 24 % of them lives 7 miles away from the school.

So, 7 miles away = 24 % of 0.37 x

= 24 / 100 ( 0.37 x )

= 0.24 ( 0.37 x)

= 0.09 x

In percentage:

= 9 %

Therefore, we get that, the percentage of the students travel over seven miles to school by train is 9 %.

Answers

The roses that Leanna cut in her front yard is 28 roses.

How to calculate the value?

From the information, she uses one quarter of her roses to make a bouquet of a dozen flowers. Therefore, the total flowers will be:

= 12 ÷ 1/4

= 12 × 4

= 48 flowers

Since she cuts some roses in her front garden and another 20 in her back garden, the number that she cut in the front garden will be:

Stop light A changes color every 45 seconds and Stop light B changes color every 80 seconds. Both Stop lights just changed. After how many seconds will the stoplights change color at the same time?

Answers

The stoplights will change color after 720 seconds. at the same time again.

Given: Stoplights A and B alternate between changing colors every 45 and 80 seconds, respectively.

One copy of each of the unique components and the common factor make up the Least Common Multiple (LCM).

The least common multiple of 45 and 80 is the amount of seconds before they change color simultaneously once more.

Since 80 = 5 x 2 x 2 x 2 and 45 = 5 x 3 x 3 respectively

A least common multiple of 45 and 80 is equal to 2x2x2x2x3x3x5 = 720.

Answers

the salesperson will be paid $ 844.2 for the one pickup they sell for $ 18,760 as 4.5 % commission is theirs.

We are given that the selling price of a pick up item is given as:

Selling price = $ 18,760

Now, it is also given that, on every sale, the salesperson gain a commission of 4.5 % as their pay.

The money they get paid for one pick up that they sell will be calculated by finding the percentage. So, we get that:

Money = 4.5 % of $ 18,760

Money = 4.5 / 100 × $ 18,760

Money = 0.045 × $ 18,760

Money =  $ 844.2

Therefore, we get that, the salesperson will be paid $ 844.2 for the one pickup they sell for $ 18,760 as 4.5 % commission is theirs.

Using the average rate of change concept, we have that:

The rate of the height is of 9.5 feet per minute.The table with a rate of -3 is given by: A 2-column table with 4 rows. Column 1 is labeled x with entries negative 22, negative 21, negative 20, negative 19. Column 2 is labeled y with entries 2, negative 1, negative 4, negative 7.

What is the average rate of change of a function?

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

For item 1, when the time in minutes changes by 1, the height changes by 9.5 units, hence the rate is given by:

r = 9.5/1 = 9.5 feet per minute.

For item 2, we want a table with a rate of -3, hence, when the first column changes by 1, the second column should always change by -3, hence the table is:

A 2-column table with 4 rows. Column 1 is labeled x with entries negative 22, negative 21, negative 20, negative 19. Column 2 is labeled y with entries 2, negative 1, negative 4, negative 7.

In this system we have a geometrical system formed by two right triangles with a common hypotenuse. Right triangles are triangles where one of its internal angles are right angles and the sum of the measures of the internal angles within a triangle equals 180°. Then, this geometrical system can be modelled by using the following linear equations:

A company makes pencils. they sell each pencil for $10.
Their revenue is represented by R= 10x
The cost to make the pencils is $3 each with a one time start up cost of $5000.
Their cost is represented by C= 3X+5000

1.Find the profit, P, (P=R-C) when the company sells 1000 pens.
2. Find the number of pens they need to sell to break even ( when R=C)

Answers

We have the profit fomula:

P = R - C

= $10.x - ($3.x + 1000)

= $7.x - 1000

1. If the company sells 1000 pens:

P = $7 . 1000 - $1000

= $6000

2. If they want to break even:

P at least = 0

Assume P = 0

=> $7.x - $1000 = 0

=> x = 1000/7 ≈ 142,86

So if they want to break even, they have to sell at least 143 pens

What time does the shipment arrive in Dallas (GMT -6) , if it departs Edmonton (GMT -7) at 14:45 p.m. on Thursday? United Airlines has a 3 hour 45 minutes flight.

Answers

At 17:30 the shipment arrive in Dallas (GMT -6) , if it departs Edmonton (GMT -7) at 14:45 p.m. on Thursday.

                   

The time difference of two zone is -7-(-6) = -1

The shipment departs at 14:45 pm

flight took time = 3:45 min

adding the time = 14:45 + 3:45

                           = 18:30

So it arrived at Dallas at 18:30 according to Edmonton (GMT -7)

It arrived in Dallas according to Dallas (GMT -6) = 18:30 - 1 hour

                                                                                = 17:30

What is time zone?                    

A time zone is a region where everyone adheres to the same standard time for social, business, and legal activities.

Coordinated Universal Time (UTC), which ranges from UTC12:00 to UTC+14:00, is used to determine all time zones. Most zones have full hour offsets, but some, like those in India, South Australia, and Nepal, have additional offsets of 30 or 45 minutes.
