Answer:

They will meet in 2.25 hours or 2 hours 15 minutes

Step-by-step explanation:

At any point in time;

distance = speed * time

Let the number of hours at which they meet be x

In x hours, the distance traveled by Karen will be 59 * x = 59x miles

In same x hours, the distance traveled by Ricardo will be 65 * x = 65x miles

Since they are traveling in opposite directions, the distance traveled at that time by Karen will be less than what Ricardo has traveled since he is traveling at a greater speed

However, the sum of whatever they have traveled will be equal to the distance between them

thus;

59x + 65x = 279

124x = 279

x = 279/124

x = 2.25 hours

Step-by-step explanation:

The total cost of the tent is 409.86

------------------------------------------------------

explanation:

230×0.65=149.50

230+149.50=379.50×.08=30.36

379.50+30.36=409.86

(Hope this helps :) )

============================================================

Explanation:

65% = 65/100 = 0.65

65% of 230 = 0.65*230 = 149.50

When applying markup, the store increases the cost by $149.50 to get the retail price of 230+149.50 = 379.50, which is the price the customer sees. This is the price before tax.

As a shortcut, we can say 1.65*230 = 379.50 because 1.65 = 1 + 0.65 = 100% + 65%. So 1.65 effectively means "increase the value by 65%"

Similarly, the multiplier 1.08 means "increase by 8%". The cost after tax would be 1.08*379.50 = 409.86 which is the answer

----------

As an even quicker shortcut, we can do both increases at once to say:

1.65*1.08*230 = 409.86

The order of multiplication doesn't matter. The two multipliers 1.65 and 1.08 can be combined into 1.65*1.08 = 1.782 which represents a 78.2% increase overall. After the mark up and tax are considered, the jump from $230 to $409.86 is 78.2%

We can apply the percent change formula to confirm this

A = old value = 230

B = new value = 409.86

C = percent change

C = [ (B-A)/A ] * 100%

C = [ (409.86-230)/230 ] * 100%

C = 0.782 * 100%

C = 78.2%

So it might be tempting to say 65% + 8% = 73%, but as you can see above, that calculation is not true.

Answer: AC/EA = AB/DA

Step-by-step explanation:

Answer:

P = 131 degrees

Step-by-step explanation:

We know that the sum of the interior angles of a triangle is 180 degrees

The exterior angles shown form a straight line with the corresponding interior angle

So the two interior angles can be calculated

The sum of two angles on a straight line is 180 degrees

By subtracting the exterior angles from 180, we can get the two interior angles which we can add to the angle at P to give 180

Thus;

P + (180-162) + (180-149) = 180

P + 18 + 31 = 180

P = 180-31-18

P = 131

Answer:

32 years

Step-by-step explanation:

Given data

Principal= $5

Rate= 5%

FInal amount= $25

Time=???

Applying the compound interest formula for time

t= ln(A/P)/r

t= ln(25/5)/0.05

t= ln(5)/0.05

t= 1.60/0.05

t= 35 years

Hence the time is 32 years

The answers of questions given are explained .

Revenue is the money generated from normal business operations, calculated as the average sales price times the number of units sold. It is the top line (or gross income) figure from which costs are subtracted to determine net income. Revenue is also known as sales on the income statement.

Total Revenue = Number of Units Sold X Cost Per Unit

According to the question

a> The company wants to reduce total expenses to $1,300.

Then expenses would i cut is from

Rent expenses as all other expenses are very important but we can try to lower out rent expenses by $1,300.

b>After the decision the impact will be on profit is

It will increase our profit by $1,300 as

Profit = Sales - Expenses  

c>if the company increases prices 20%

i.e

If price will be increases then revenue will also increase by 20%

As  Total Revenue = Number of Units Sold X Cost Per Unit

Therefore ,

Total Revenue = 356500 * 1.2

                         = 427800

d> If the cost of supplies (inputs) decreases,

The impact on profit is it will increase

as if cost of supplies decreases that is it will decrease the supplies expenses also which will cost in less expense and higher profit .

e> If the supply of a product goes down,

It will lower the revenue or sales also

as Total Revenue = Number of Units Sold X Cost Per Unit  

But if supply of a product goes down and price per unit  increase it will maintain the sales or revenue  .

Hence, The answers of questions given are explained .

Answer:

C

Step-by-step explanation:

This method is the best because it will survey the customers under one condition : every 10. If the store gets a lot of customers, then this should be easier to do. The rest are mostly dependent on what they do and that influences the survey. However, C makes it so that every 10 people are surveyed.

Step-by-step explanation:

Answer:

A = $560.00

Step-by-step explanation:

I = A - P = $60.00

Formula:

[tex]A = P(1 + rt)[/tex]

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year.

Solving our equation:

A = 500(1 + (0.06 × 2)) = 560

A = $560.00

The total amount accrued on a principal of $500.00 at a rate of 6% per year for 2 years is $560.00.

2x² + 6x + 15 = 0

Step-by-step explanation:

Given quadratic equation is,

-2x² - 6x = 15

We have to convert this equation in the standard form of the quadratic equation,

ax² + bx + c = 0

(-2x² - 6x) = 15

-2x² - 6x - 15 = 0

2x² + 6x + 15 = 0

expanded:

y = sin(4x)*sin(4x)*cos(3x)

need to use the product rule and chain rule

look at individual derivatives, use chain rule

d/dx sin(4x) = 4cos(4x)

d/dx cos(3x) = -3sin(3x)

put it together using product rule

dy/dx = 4cos(4x)*sin(4x)*cos(3x) + 4cos(4x)*sin(4x)*cos(3x) - 3sin(3x)*sin(4x)*sin(4x)

simplify

dy/dx = 8cos(4x)*sin(4x)*cos(3x) - 3sin(3x)*sin2(4x)

answer is A.

Step-by-step explanation:

Dave + 6 friends = 7 friends in total

84 ÷ 7 = 12

Each friend paid $12

Each of them paid $12 for the Meal.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

We have,

Dave and 6 friends went to dinner.

Total amount of meal= $84

So, each of them paid

= 84/ 7

= 12

Thus, each of them paid $12.
