Plz help me with this question

Answer: 9= -1.5 or -3/2

               10= -11/6 or 1.8333

                11= -10.9

                 12= 3.535

                   13= Town A is -3.33 Town B is -3 2/5, 2/5= .44, so town B is colder, as it is -3.44

                     14= I'm not sure about number 14, sorry about that

9.

Explanation: So for question 9, you need to find the LCD (Least common denominator) so you list out the multiples of 8 and 4, when doing so, you find out that 8 is the LCD of both, since 8 is both a multiple of itself and of 4.

So, to get the answer, you do 4 * 2 and anything you do to the denominator (bottom number), you do to the nominator (top number).

So now you have -8/3/8 +6/2/8 then you just add the nominators and whole numbers like normal. You get, -2/1/8 (Remember you are adding a positive number to a negative number.)

Answer: -2/1/8

10.

Explanation: Same process as question 9.

Answer: -4/1/12

11.

Explanation: Read -7.3 out loud, it would be negative seven and 3 tenths, that makes it easy to convert as a fraction. It would be -7/3/10. Do the same for the other number, and you have -3/6/10, then you just add. You get -10/9/10.

Answer: -10/9/10

12.

Explanation: Same process as question 11. (You're in the thousandths now.) You get 3/535/1000. Reduce.

Answer: 3/107/200

13.

Explanation: You have 2 options here, to convert the decimal into a fraction, or to convert the fraction into a decimal, I'll be changing the fraction into a decimal, you wanna write it as a 10 as a denominator, so to get to 10 you multiply the denominator by 2, and anything you do to the denominator, you do to the nominator. So, -3/2/5 as a decimal is: -3.4, then you go ahead and compare them and you can see that the temperature in town A is colder.

Answer: The temperature in town A is colder.

14.

Explanation: For this one, you just subtract or add the amount to 7number. The dates don't matter, just telling you to do it in that order.

60.68 + 75.50 = 136.18

136.18 - 25.16 = 111.02

111.02 - 82.05 = 28.97

28.97 + 59.95 = 88.92

Answer: $88.92

Answer:

$150

Step-by-step explanation:

ok, so first you want to create your equations. let s=shirts, and p=pants. 4s+3p=159, and 3s+2p=113. next you want to get one variable in each equation to be the same. I multiplied the first by 2 and the second by 3 to make the ps the same. now we subtract our equations. (9s+6p=339) - (8s+6p=318) this gives you s=21. Now we put that in to solve for p, it doesnt matter which of the 4 equations. 4(8)+3p=159 = 3p=127 = p=42 1/3. now we just multiply them to find the cost of 5 of each. which is the answer above.

Answer:

y = x⁴- 5x² + 4

y = x(x + 3)(x - 2)

Step-by-step explanation:

1). y = x⁴- 5x² + 4

      = x⁴- 4x² - x² + 4

      = x²(x² - 4) - 1(x²- 4)

   y = (x² - 1)(x² - 4)

   y = (x - 1)(x + 1)(x - 2)(x + 2)

  Therefore, zeros of this polynomial are,

   x = -2, -1, 1, 2

   From the given graphs, first graph has the zeros (x-intercepts) as x = -2, -1, 1, 2.

   So the graph (1) represents the polynomial → y = x⁴- 5x² + 4

2). Second graph shows the x-intercepts at x = -3, 0, 2

   Since, y = x(x + 3)(x - 2) is the polynomial with x intercepts at x = -3, 0, 2

   Therefore, y = x(x + 3)(x - 2) represents the second graph.

Answer:

when x = -5 y is -48

when x is -1 y is -8

when x is 0 y is 2

when x is 1 y is 12

Answer:

The answer would be B. 12 + 6n is greater than or equal to 30, so n is less than or equal to 3.

explanation:

I'm bad with explaining things, but I'll try my best to explain why this is the right answer.

12 + 6n ≥ 30, so n ≤ 3

let's start with the 12 at the beginning of the inequality, Annie already has $12, so the 12 in the inequality shows the amount of money she already has being added to the $6 per hour of babysitting she needs to do (n).

Now for the + 6n, the plus is there to show that the $12 Annie already has is being added to the 6n. The 6n then represents the $6 Annie makes each hour and the n represents how many hours she needs to babysit in order to get $30. The 6 is being multiplied by the amount of hours she needs to babysit to show how much money Annie would make. Then you add on the $12 she already has.

Annie then needs at least $30, but if she makes more than $30 then she will simply have more money than needed, therefore you use the greater than or equal to sign to show that she can have more money than just $30 after working.

I hope this helps, and sorry if my explanation is hard to understand lol.

Answer:

B

Step-by-step explanation:

The number line shows that x must be greater than or equal to 0 and less than but not equal to 3. This means that the only answer that does not reflect this is 0<x<3, because again, x must be greater than or equal to 0. Not just greater than.

Answer:

✔ 3r > 34

✔ r > 11.3

✔ The squirrel ran faster than 11.3 feet per second.

Step-by-step explanation:

1. The Squirrel's speed is 3r > 34

2. The solution of the inequality is r > 11.3

3. The interpretation is: The squirrel ran faster than 11.3 feet per second.

Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

A squirrel runs across a road in 3 seconds.

The road was more than 34 feet wide.

1. The Squirrel's speed is

3r > 34

2. The solution of the inequality is

r > 34/3

r > 11.3

3. The interpretation is: The squirrel ran faster than 11.3 feet per second.

Answer:

2.665 ounces approximately or .1665625 pounds

Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

principal = $5,000

interest rate = 2.3%

account A: compound monthly for 10 years

account B: compound continuously for 10 years

account A: compound monthly for 10 years

A = P (1 + r/12)^ r*t

 = $5,000 (1 + .023/12)^ 12(10)

= $6,291.6

account B: compound continuously for 10 years

FVn = PV * e^r*t

      = $5,000 * e ⁽⁰ ⁰²³ˣ¹⁰⁾

      = $6,293

Gregory may chose account B. (but the difference is only $1.40)

Gregory may choose account B.

Given that,

Based on the above information, the calculation is as follows:

[tex]A = P (1 + r\div 12)^ {r\times t} \\\\= $5,000 (1 + .023\div 12)^ {12(10)}[/tex]

= $6,291.6

[tex]FVn = PV \times e^{r\times t}\\\\ = $5,000 \times e^ {0.023\times 10}[/tex]

= $6,293

Therefore we can conclude that Gregory may choose account B.
