Answer:

The correct answer is B. 20,000

Step-by-step explanation:

To determine the man's total monthly salary, we can set up a simple equation using the given information. Let's denote the total monthly salary as "x."

According to the information provided, 33% of the man's monthly salary is equal to Birr 6600. We can express this relationship mathematically as:

0.33x = 6600

To solve for "x," we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 0.33:

x = 6600 / 0.33

Evaluating the right side of the equation gives:

x ≈ 20,000

Therefore, the man's total monthly salary is approximately Birr 20,000.

Hence, the correct answer is B. 20,000.

Answer:

220

Step-by-step explanation:

Multiply 15 times 10 =150

150+70=220

Hope this helps :)

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

Explanation:

After 10 weeks, he'll deposit a total of 15*10 = 150 dollars on top of the $70 already in the account. This means the grand total is 150+70 = 220 dollars

If you need to use algebra, then an algebraic expression you can use is 70+15x where x is the number of weeks. Replace x with 10 and you'll end up with 70+15*10 = 70+150 = 220. It's effectively the same idea and steps as the previous paragraph, but now we're involving a variable.

To find the area of Kim's bedspread, we first need to calculate the radius of her circular bed. Since the diameter is 7 feet, the radius is half of that, which is 3.5 feet. The area of Kim's bedspread is approximately 86.59 square feet.

Next, we need to calculate the total width of the bedspread. We know that it hangs over the side 1 3/4 feet all the way around, which means the total width of the bedspread is:

1 3/4 feet + 1 3/4 feet = 3 1/2 feet

Now we can calculate the total diameter of the bed and the bedspread. It is:

7 feet + 3 1/2 feet + 3 1/2 feet = 14 feet

Finally, we can calculate the area of the bedspread using the formula for the area of a circle:

Area = π x radius^2

Plugging in our values, we get:

Area = π x 3.5^2
Area = 38.48 square feet

Therefore, the area of Kim's bedspread is approximately 38.48 square feet.

To find the area of Kim's bedspread, we first need to find the diameter of the bedspread, which includes the bed and the overhanging part.

1. Find the total overhang on the diameter:
Since the bedspread hangs over the side 1 3/4 feet all the way around, we need to add this overhang twice (once for each side of the diameter).
Total overhang = 1 3/4 + 1 3/4 = 3 1/2 feet

2. Find the diameter of the bedspread:
Diameter of the bed = 7 feet
Diameter of the bedspread = Diameter of the bed + Total overhang = 7 + 3 1/2 = 10 1/2 feet

3. Find the radius of the bedspread:
Radius of the bedspread = Diameter of the bedspread / 2 = 10 1/2 / 2 = 5 1/4 feet

4. Find the area of the bedspread:
Use the formula for the area of a circle, which is A = πr², where A is the area and r is the radius.
A = π * (5 1/4)²
A ≈ 3.14 * (5.25)²
A ≈ 3.14 * 27.5625
A ≈ 86.590625

So, the area of Kim's bedspread is approximately 86.59 square feet.

The claim that two situations are similar, despite major differences being ignored and only minor similarities being emphasized, is a fallacy known as false analogy.

False analogy is a logical fallacy that occurs when two situations are compared based on minor similarities while ignoring significant differences. It involves drawing an invalid or weak comparison between two unrelated or dissimilar things. In this fallacy, the person making the claim assumes that because two situations share some superficial similarities, they must be similar in all aspects. However, this overlooks the fundamental differences that make the situations distinct.

For example, if someone argues that banning the use of plastic bags in a city is similar to banning the use of cars, based solely on the fact that both involve restricting a common item, they would be committing a false analogy. While there may be minor similarities between the two situations, such as the concept of imposing restrictions, there are major differences in terms of environmental impact, necessity, and alternatives. Ignoring these significant differences leads to an invalid comparison and can result in flawed reasoning.

In conclusion, false analogy occurs when two situations are deemed similar based on minor similarities while disregarding major differences. It is essential to carefully evaluate the relevant factors and understand the nuances of each situation before drawing comparisons to ensure logical and valid arguments.

To be at least 50% sure of knowing the identity of at least one of the missing cards, you need to remove and look at 46 cards from the deck.

To understand this reasoning, let's consider the worst-case scenario. Initially, when you haven't removed any cards, there are 52 possible cards that could be missing. As you start removing cards, the number of possible missing cards decreases. For each card you remove, the probability of it being one of the missing cards increases.

In the worst-case scenario, the missing cards are the last three cards remaining in the deck after you've removed 49 cards. At this point, you have narrowed down the possible missing cards to just three. Now, removing one more card guarantees that you will know the identity of at least one of the missing cards because you have eliminated all other possibilities.

Therefore, to be at least 50% sure of knowing the identity of at least one of the missing cards, you need to remove and look at 46 cards (49 cards removed initially, leaving three possible missing cards, and then one additional card to determine the identity).

By the time you have removed 46 cards, there is a high probability that you have encountered one of the missing cards, thus meeting the requirement of being at least 50% sure of its identity.

Assuming that the account earns the interest as simple interest, to calculate the amount Mrs. Martin will have after 18 months, you have to use the following formula:

Where

A is the accrued amount

P is the principal amount

r is the interest rate expressed as a decimal number

t is the time expressed as years

She deposited $2300, this is the principal amount.

The interest rate of the account is 1.5%, to express it as a decimal value you have to divide it by 100

To express the time in "years" you have to divide the given months by 12

Now that all values are expressed in their corresponding units, you can calculate the final balance in her account as:

After 18 months she will have $2351.75 in her account.

Step-by-step explanation:

1%2F5n + 51%2F5 = 302%2F5 - 1%2F6n

make the 3rd term an improper fraction

multiply equation by 30, cancel the denominators, resulting in:

6n + 6(51) = 6(152) - 5n

6n + 306 = 912 - 5n

6n + 5n = 912 - 306
