Compute the estimated cost of the ending inventory, assuming the gross profit rate is 35%.

Answers

The estimated cost of the ending inventory, assuming the gross profit rate is 35% is; $11250

How to find Estimated Cost?

Let us first calculate the gross profit;

Gross Profit = Sales * Profit%

Gross Profit = 395000 * 35%

Gross Profit = $138250

Cost of goods sold = Sales - Gross Profit

Cost of goods sold = 395000 - 138250

Cost of goods sold = $256750

Cost of ending inventory = Cost of goods available for sale - Cost of goods sold

Cost of ending inventory = 268000 - 256750

Cost of ending inventory = $11250

Multiply through by x - 3

Then factor the result

4*(x - 3) / (x - 3) = x*(x - 3)

4 = x * (x - 3 )                          Remove the brackets

4 = x^2 - 3x                            Subtract 4 from both sides

Answer: Radius = 10.48 cm

Step-by-Step Solution:

Radius (r) = ?
Area (A) = πr² = 345 sq. cm

Therefore,
πr² = 345
3.14 * r² = 345
r² = 345/3.14
r² = 109.87
r = √109.87

Answers

Based on the statistics from the worldwide health organization, the percentage change in those living with the disease is 19.7% and the change in those who have died is 70%.

This shows that the disease is getting worse and not being treated effectively.

What do the statistics on the disease show?

The number of those living with the disease went from 71 million to 40 million:

= (85 - 71) / 71

= 19.7% increase

The percent change in those who have died is:

= (6.8 - 4) / 4

= 70% increase

This shows that the measures being implemented against the disease are not working because both the number of people who have the disease and have died from it has increased.

The system of inequalities of the graph is (a) y > x² + 2x - 3 and y > 2x + 3

How to determine the inequalities?

The complete question requires that we determine the system of inequalities of the graph (the graph is attached)

Going by the list of options, the equation of the quadratic curve is:

y = x² + 2x - 3

From the graph, we can see that:

The curve uses a dotted lineThe upper part is shaded

The above means that the inequality is greater than i.e. >

So, we have:

y > x² + 2x - 3

The above eliminates options (b) and (c)

From the graph, we can see that the straight line has a positive slope, a dotted line and the upper part is shaded.

The linear inequality in option (a) has the above characteristics.

So, the inequality is:

y > 2x + 3

Hence, the system of inequalities of the graph is (a) y > x² + 2x - 3 and y > 2x + 3

There is a 45% chance of snow on Friday. Thereis a 78% chance that I will go sledding if it snows. What is the probability that I will go
sledding?

Answers

Answer:

35.1% chance of going sledding

Step-by-step explanation:

45% chance of snow on Friday

Convert percentage to decimal form (divide by 100)

45% = 0.45

78% chance of sledding if it snows

Convert percentage to decimal form (divide by 100) to multiply

78% = 0.78

Multiply to find the probability of both occurring

0.78 * 0.45 = 0.351

Convert back into a percentage (multiply by 100)

0.351 = 35.1% chance of sledding
