ycow [4]

Answer:

Correct answer = 20 miles

Step-by-step explanation:

The mistake she made was that she made was that she  multiplied the amount with 3 instead of dividing it.

The incorrect way -

$60 = 3 × 60 = 90 (Her multiplication is also incorrect as 3 × 60 = 180)

Corrected method -

$60 = \frac{60}{3} = 20 miles

Ms. Winter is organizing a march where people will walk in equal rows. She wants to have more than 611 people in the
Flauer [41]

Answer:

<h3>D.  p2 + 27p > 770</h3>

Step-by-step explanation:

Ms. Winter wants to have 27 more rows than people in each row.

The number of people in each row is represented by p.

The number of rows is represented by p + 27.

Ms. Winter wants to have more than 770 people in the march.

To find the total number of people in the march, find the product of the rows and the people in each row.

Set up an inequality to represent the situation.

p(p + 27) > 770

p2 + 27p > 770

An object oscillates 4 feet from its minimum height to its maximum height. The object is back at the maximum height every 3 seco
bulgar [2K]

Answer:

y=2\text{cos}((\frac{2\pi}{3})t)

Step-by-step explanation:

We have been given that an object oscillates 4 feet from its minimum height to its maximum height. The object is back at the maximum height every 3 seconds. We are asked to find the cosine function that can be used to model the height of the object.

We know that standard form of cosine function is y = A\cdot \text{cos}(Bt-C)+D, where,

|A| = Amplitude,

Period = \frac{2\pi}{|B|},

C = Phase shift,

D = Vertical shift.

Since distance between maximum and minimum is 4, therefore, amplitude will be half of it, that is, A = 2.

Since objects gets back to its maximum value in every 3 seconds, therefore, period of the function is 3 seconds. We know that period is given by \frac{2\pi}{|B|}, therefore, we can write \frac{2\pi}{|B|}=3, therefore, B = \frac{2\pi}{3}.

We haven't been given any information about phase and mid-line, we can assume the values of C and D to be zero .

Therefore, our function required function would be y=2\text{cos}((\frac{2\pi}{3})t).

. Where does the line y = 3x + 5 cross the y-axis?
Leto [7]

Answer: at 5

Step-by-step explanation: the 3 is the slope and the 5 is the y intercept. The y-intercept corresponds to the value of 5 when the x value is equal to 0

There are 52 weeks in a year, and you work 40 hours a week how much do you need to make an hour to make $60,000 a year?
sammy [17]
First you need to multiply 52 x 40 = 2080
then you need to divide 2080 from 60,000.
The answer will be 60000/2080 is approximately $28.85
