C. Because it uses the communitive property and moves the parenthesis around the -3. but all the other signs stay the same.

For each boat he sells, Mick earns $149 in

zavuch27 [327]

Answer: c = 149 + 0.02p

Step-by-step explanation:

From the question,

P = purchase price of the boat

C = Mick's commission

From the scenario in the question, the commission earned by Mick will be:

c = 149 + (2% × p)

c = 149 + (0.02p)

c = 149 + 0.02p

Jada added two like fractions and then wrote the answer in simplest form. The answer was 1/3. One of the addends was 3/12 . What

miss Akunina [59]

Step-by-step explanation:

The two like fractions can be set as x and y (just to use two variables).

One of them is $\frac{3}{12}$ , though, so we can set one of the variables equal to that value (I'm just going to make $y=\frac{3}{12}$ , it doesn't matter which variable you use).

We also know that adding the two variables gives us $\frac{1}{3}$ so now we can make an equation.

$x+y=\frac{1}{3} \\x+\frac{3}{12} =\frac{1}{3} \\x=\frac{1}{3} -\frac{3}{12} \\x=\frac{4}{12} -\frac{3}{12} \\x=\frac{1}{12}$

Answer:

$\frac{1}{12}$

Mrac [35]

Answer:

Step-by-step explanation:

Buys for $45 and increased the price by 120%

The new price is (45*120)/ 100 = $54

$370 /$54 ≈ 6.8

The owner must buy at least 7 jackets.

7*54 = $378

378 > 370

In a hat, you have index cards with the numbers 1 through 10 written on them. Find how many of the 10 possible numbers you can p

AURORKA [14]

8,5.7,1,3,2,4,6 is the correct order

Step-by-step explanation:

1. There are 10 numbers from 1 to 10 , thus there are 10 possible outcomes.

Determine the number of favourable outcomes for each event:

Number greater than 0 : 10 favourable outcomes ( 1,2,3,4,5,6,7,8,9,10)

Even number : 5 favourable outcomes ( 2,4,6,8,10)

Number is at least 2 : 9 favourable outcomes ( 2,3,4,5,6,7,8,9,10)

Number is at most 0 : 0 favourable outcomes ( as none of the integers from 1 to 10 are at most 0 )

Number is divisible by 3 : 3 favourable outcomes ( 3, 6,9)

Number is divisible by 5 : 2 favourable outcomes ( 5, 10)

Prime number : 4 favourable outcomes ( 2, 3, 5, 7 )

Number less than the greatest prime number : 6 favourable outcomes ( 1, 2,3,4,5,6 as 7 is the greatest prime number from the numbers of 1 to 10 )

2. The more favourable outcomes correspond with an event, the more likely the event is to happen. Thus the number is at most 0 is the least likely and the number greater than 0 is the most likely.

Let us then number the events from least likely to most likely:

Number greater than 0: 8

Even number: 5

Number is at least 2: 7

Number is at most 0:1

Number is divisible by 3: 3

Number is divisible by 5: 2

Prime number 4

Number less than the greatest prime number: 6

So the order is 8,5.7,1,3,2,4,6
