Answer:

2.7 hours

Step-by-step explanation:

Assuming that each percentage is worth the same amount of time. Then we can use the Rule of three since this is a ratio problem and we are given three values and a variable which is the amount of time that the battery lasts at 15%. This variable is represented by the letter x. To solve this we simply multiply the diagonal values and divide by the last remaining value which gives us the value of the variable like so...

100%  <====>  18 hours

 15%   <====>  x hours

(15 * 18) / 100 = 2.7 hours

Finally, we can see that 15% charge on the phone will last 2.7 hours

Not sure is there supposed to be a pic?

Step-by-step explanation:

Answer: A(t) = (6.4 ft^2/min)*t

Step-by-step explanation:

We know that Emily paints at a constant rate, and she can paint 32 ft^2 in 5 minutes.

Then if we take the quotient of these two quantities, we will find the amount she can paint in one minute, this is:

32ft^2/5min = (32/5) ft^2/min = 6.4 ft^2/min.

Then if she paints for t minutes, the area that she can cover can be written as:

A(t) = (6.4 ft^2/min)*t

This is the linear equation we wanted to find.

The value of the equation is A = 7,45,10,305 and the remainder is 0

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first number be p = 12345

Let the second number be q = 54321

Now , A = ( p x q ) / 9

Substituting the values in the equation , we get

A = ( 12345 x 54321 ) / 9

On simplifying the equation , we get

A = 67,05,92,745 / 9

On further simplification , we get

A = 7,45,10,305

And , the remainder of the equation is 0

Therefore , the value of A is 7,45,10,305

Hence , the equation is A = 7,45,10,305 and the remainder is zero

Answer:

The number of enrollments increased by 5%.

Step-by-step explanation:

Given that:

Number of students at the beginning of the year = 480

Number of students at the end of the year = 504

Change = 504 - 480 = 24

This indicates increase.

Percent of change = [tex]\frac{Change}{Old\ number\ of\ students}*100[/tex]

Percent of change = [tex]\frac{24}{480}*100[/tex]

Percent of change = 5%

Hence,

The number of enrollments increased by 5%.

Answer:

The answer is below

Step-by-step explanation:

Let x represent the number of hours of dog walking. Taylor charges $15 for the first hour and $10 for each additional hour. Therefore:

Let g(x) represent how much Taylor charges. Hence:

g(x) = 15   for 0 ≤ x ≤ 1

g(x) = 15 + 10(x - 1) = 15 + 10x - 10 = 10x + 5   for x > 1

g(x) can be represented by the piecewise function:

[tex]g(x)=\left \{ {{15\ \ \ \ \ \ for\ 0\leq x\leq 1} \atop {10x+5\ \ for\ x>1}} \right.[/tex]

Lucy charges f(x) is modeled by the piecewise function:

[tex]f(x)=\left \{ {{20x\ \ \ \ \ \ for\ 0\leq x\leq 2} \atop {10x\ \ \ for\ 0< x< 4}} \right.[/tex]

Therefore the charge for walking a dog for 2.5 hours by either Taylor or Lucy is:

For Taylor; f(2.5) = 10(2.5) + 5 = $30

For Lucy; g(2.5) = 10(2.5) = $25

Therefore Taylor charges more by walking a dog for 2.5 hours. Taylors charge is $5 more than Lucy charge ($30 - $25).

Answer:

(a) the number of 100W light bulbs is 11

(b) the daily cost of 2000 kW is $4,800

Step-by-step explanation:

charge of energy consumption up to 20 kWh = $0.05/kWh

charge of energy consumption above 20 kWh = $0.10/kWh

(a) number of 100 W light bulbs that can be run continuously for less than $10 per week

Total energy consumed by 100 W in 1 week = (0.1 kW) x (7 x 24 h)

                                                                          = 16.8 kWh

Charge associated with this consumption = $0.05/kWh

let the number of 100 W light bulbs = n

[tex]n(\frac{\$ 0.05}{kWh} \times 16.8 kWh) = \$10\\\\n(0.84) = 10\\\\n = \frac{10}{0.84} \\\\n = 11.9[/tex]

Since 0.9 is not a whole number, the number of 100 W light bulbs is 11.

(b) if 2000 kW is used continuously

total energy consumption = 2000 kW x 24 h = 48,000 kWh

The daily cost is calculated as;

[tex]= \frac{\$0.10 }{kWh} \ \times \ 48,000 kWh\\\\= \$ 4,800[/tex]

A particular electric utility charges customers different rates depending on their daily rate of energy consumption :

(a) the number of 100W light bulbs is 11

(b) the daily cost of 2000 kW is $4,800

Given :

Charge of energy consumption up to 20 kWh = $0.05/kWh

Charge of energy consumption above 20 kWh = $0.10/kWh(

Part a)

Number of 100 W light bulbs that can be run continuously for less than $10 per week

Charge associated with this consumption = $0.05/kWh

Let the number of 100 W light bulbs = n[tex]n\left(\frac{\$0.05}{kWh}\cdot16.8kWh\right)=\$10\\n\left(0.84\right)=10\\n=\frac{10}{0.84}\\n=11.9[/tex]

Since 0.9 is not a whole number.

Thus, the number of 100 W light bulbs is 11.

Part b)

2000 kW is used continuously

Total energy consumption = 2000 kW x 24 h

Total energy consumption  = 48,000 kWh

The daily cost is calculated by:

[tex]\frac{\$0.10}{kWh}\cdot48000\ kWh

Daily cost=\$4800[/tex]

Answer:

There are 151,200 possible license plates.

Step-by-step explanation:

The order in which the digits are positioned is important(for example, 012345 is a different plate than 102345). No repeat digits are allowed, which means that we use the permutations formula to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

In this question:

There are 10 possible digits(from 0 to 9).

The plate has 6 slots.

So

[tex]P_{(10,6)} = \frac{10!}{(10-6)!} = 151200[/tex]

There are 151,200 possible license plates.

Answer: 28 p is the cost of one crayon.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

Marcin buys 7 rulers and 15 crayons for £7.

A ruler costs 12p more than a crayon.

now,

To solve this problem we're going to use an equation.

First let's write down the information that we do know.

Let's use (r) for ruler and (c) for crayon.

So 7 rulers and 15 crayons cost £7 (or 700 pennies)

--> 7r + 15c = 700

But we also know that r = c +12

So we can substitute c + 12 into the first equation where r is at the moment.

7(c+12) + 15c = 700

Now let's expand the brackets.

We multiply 7 by c to get 7c

and 7x12 t0 get 84

7c + 84 +15c = 700

22c + 84 = 700

Here I'm going to take 84 away from both sides.

22c = 616

616 divided by 22 is 28

so c = 28

hence, Each crayon therefore costs 28p.
