Mary Moneypenny went to her bank each week and opened a club account. She deposited $21.75 per time period. If she made 12 deposits before interest was credited, how much would she have deposited before interest was credited?

Answers

Answer:

The $261 Mary deposited before interest was credited .

Step-by-step explanation:

As given

Mary Moneypenny went to her bank each week and opened a club account. She deposited $21.75 per time period.

She deposited $21.75 per time period.

If she made 12 deposits before interest was credited.

Than

Mary deposited before interest was credited = 21.75 × 12

                                                                           = $ 261

Therefore the $261 Mary deposited before interest was credited .

lets see step by step,
she goes 12 times to the bank and made a deposit of $21.75 each time, therefore she have deposited:

deposit = 12*21.75 = $261

that is the amount she deposited before receiving any interest.

You answer is the second

Answer:

B: x = -y+6

Step-by-step explanation:

Since y = x+6:

Bring x and y to their opposite sides:

What temperature is 15 degrees lower than seven degrees Celsius and how would you work it out

Answers

The question is asking us to find the temperature which  is 15 degrees lower than seven degrees Celsius.

The mathematical symbol used for lower than is a subtraction sign that is -.

15 lower than 7 degree = 7-15 = -8.

7 and 15 have opposite sign so will  be subtracted .The answer will take the sign of the bigger number.

The  temperature that  is 15 degrees lower than seven degrees Celsius is -8°C

To figure this out, subtract 15 from 7 and you get –8. So your answer is -8˚ C.

Hope that helps:)

Which type of species from above is more likely to be an invasive species? Why?

Answers

Answer: Here's my answer

Step-by-step explanation:

To determine which type of species is more likely to be an invasive species, we need to consider certain characteristics and factors that contribute to invasiveness. While the question does not provide specific options or types of species, I can provide you with some general information about invasive species to help you understand which characteristics make a species more likely to be invasive.

1. Fast growth and reproduction: Invasive species often have a rapid growth rate and reproduce quickly, allowing them to outcompete native species for resources. This can lead to a decline in biodiversity and disrupt ecosystem balance.

2. Lack of natural predators or diseases: Invasive species may have evolved in a different habitat where they are not naturally controlled by predators, parasites, or diseases. This lack of natural checks and balances can allow invasive species to thrive and spread rapidly in new environments.

3. Ability to adapt to new environments: Invasive species are typically able to adapt and survive in a wide range of environmental conditions. They can tolerate different climates, soil types, or water conditions, which allows them to establish and thrive in new areas.

4. High reproductive capacity and dispersal mechanisms: Invasive species often have efficient mechanisms for dispersal, such as producing large numbers of seeds, having long-distance dispersal methods (e.g., wind, water, or hitchhiking on animals), or having a strong ability to reproduce vegetatively (e.g., through runners, rhizomes, or fragmentation).

5. Competitive advantage over native species: Invasive species may possess traits that give them a competitive edge over native species. This could include traits such as rapid growth, efficient resource utilization, allelopathy (the ability to release chemicals that inhibit the growth of other plants), or resistance to herbivores.

It's important to note that the likelihood of a species being invasive can also depend on the specific ecosystem and context. Some species may be invasive in one region but not in another due to differences in environmental conditions and the presence of natural controls.

To determine which specific species from the given options is more likely to be invasive, we would need additional information about their characteristics, native range, and ecological impact.

For her semester project, an art student was required to complete an oil painting that was at least 5 square feet in area. If the student wanted to make a painting that was 3 3/4feet wide, what is the minimum height (in feet) that it could be?

Answers

The area of the figure would have to be:
Height × Width

The minimum area would be:
5×5=25 square ft.

To find the minimum height,we devide the area by it's width.

If the painting is 3 3/4 feet wide,the minimum height would have to be:
25÷3 3/4
=25/3×3/4
=25/4 or 6 1/4 ft.

Thus the answer would be:25/4 or 6 1/4 ft.

Hope it helps!

The minimum height would be roughly 1.67 feet.
