Answer:

-$5.50>x>$20

Elena has more than -$5.50 but less than $20.

Step-by-step explanation:

Ok, so the question says that Elena has -$5.50 in her account. That means that she owes someone ( the bank) $5.50.

Elena then mows the lawn which may have paid off her debt. But we don't know that for sure.

All they give us is that Elena has less than $20 in her bank account.

So your answer may look like this:

-$5.50>x>$20

Elena has more than -$5.50 but less than $20.

Answer:

Part A: 4,300 ≥ 2500 + 0.12s

Part B: Less than or equal to $15,000

Part C: In the image

Step-by-step explanation:

For Part A: The total needs to be at least 4,300. So 4,300 is greater than or equal to how much she earns. 2,500 is the base pay, and it is added to 0.12s, which represents 12% of sales (s).

For Part B:

Using the inequality, solve for s

4,300 ≥ 2500 + 0.12s

Subtract 2500 from both sides

1800 ≥ 0.12s

Now divide both sides by 0.12 to isolate s

15000 ≥ s

So sales must be less than or equal to 15000.

Part C:

Suppose $24,000 is deposited into an account paying 7.25% interest, which is compoundedcontinuouslyHow much money will be in the

ozzi

Answer:

$49560

Explanations:

The amount deposited is the principal

The principal, P = $24,000

Interest rate, r = 7.25% = 7.25/100 = 0.0725

Time, t = 10 years

Since the interest is compounded continuously, the amounte^ formula is given as:

$A\text{ = P}\times\text{e}^{rt}$

Substitute P = 24000, r = 0.0725, and t = 10 into the formula above:

$\begin{gathered} A\text{ = 24000}\times e^{0.0725(10)} \\ A\text{ = 24000}\times e^{0.725} \\ A\text{ = }24000\text{ }\times\text{ }2.065 \\ A\text{ = }49560 \end{gathered}$

$49560 will be in the account after 10 years if no withdrawal or deposit is made

You are making an umbrella that is shaped like a regular octagonal pyramid.

guajiro [1.7K]

Answer:

80 ft²

Step-by-step explanation:

From the diagram

The umbrella has a total of 8 triangle.

Applying

A = 8(bh)/2

A = 4bh...................... Equation 2

Where A = Amount of fabric, b = base of one of the triangle in the octagonal pyramid, h = height of the triangle.

From the diagram,

Given: b = 4 ft, h = 5 ft

Substitute these values into equation 2

A = 4×4×5

A = 80 ft²
