Answer:

y=40

Step-by-step explanation:

x   y

9   15

24  y

9/24=15/y

24*15=9y

360=9y

40=y

Therefore, 40 is correct.

If x and y are proportional, when x=24 we get y=40. Therefore, option (3) is the correct answer.

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".

Given that, in a proportional relationship when x=9 we know that y=15.

If x is directly varies to y we get

x∝y

x=ky

Now, 9=15k

k=9/15

k=3/5

So, equation is x=3/5y

When x=24, we get

24=3/5y

24×5=3y

y=40

Therefore, option (3) is the correct answer.

Answer:

Interes= [Principal*(1+tasa de interes)^x] - Principal

Step-by-step explanation:

Dada la siguiente información:

Principal= $1,000

Tasa de interes= 3% anual = (0.03/12)= 0.0025 mensual

Número de periodos= x

Para calcular el interés ganado, hay que usa la formula siguiente:

Interes= [Principal*(1+tasa de interes)^x] - Principal

Por ejemplo, para 6 meses:

Interes= [1,000*(1.0025^6)] - 1,000

Interes= $15.09

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

has a ratio of 6 to 1

Answer:

B is the correct answer

Answer: you are correct. The answer is the first option and if you don't believe me look at my explanation.

Step-by-step explanation: Since a ratio can also be written as a fraction, 3:12 = 3/12. So what you do is simplify 3/12 to get 1/4 which equals 1:4.

Answer:

a. y= -1221x+19820

b. For every year the car value decreases $1,221.

c. $11,273

Step-by-step explanation:

a. (y2-y1)/ (x2-x1)

(16157-17378)/(3-2)= -1221

For the y-intercept you would just add 1221 twice to the value of the 2 year old car, get the value of 0 years.

c. -1221(7) +19820 =$11,273

Answer:

1. Amount of rain is the explanatory variable and yield of corn is the response variable.

Step-by-step explanation:

Explanatory Variable is the causal variable, which effects the other variable.

Response Variable is the resultant variable, which is effected by the other variable.

In this case, amount of rain effects the yield of corn (bushels per acre).

So, Amount of rain being causal effecting variable - is Explanatory Variable. Corn yield, being resultantly effected variable - is Response Variable.

Answer:

$0

Step-by-step explanation:

Given that:

Preparation and sowing cost = $240,000

Cost of harvest after a year = $93,200

Worth of crop = $350,000

Interest rate (r) = 7% = 0.07

Net present value of Investment :

[(worth - Cost after 1 year) / (1 + r)] - initial investment cost

[(350,000 - 93,200) ÷ (1 + 0.07)] - 240,000

[256,800 / 1.07] - 240,000

$240,000 - $240,000

= $0

Answer:

m<1

Step-by-step explanation:

If the expression is in the form of [tex]ax^2+bx+c[/tex], then the condition for having 2 different real roots is

[tex]b^2-4ac>0\cdots(i)[/tex].

The given expression is [tex]x^2-2x+m[/tex].

Here, a=1, b=-2 and c=m.

So, by using equation (i),

[tex](-2)^2-4(1)(m)>0[/tex]

[tex]\Rightarrow 4-4m>0[/tex]

[tex]\Rightarrow 4m<4[/tex]

[tex]\Rightarrow m<4/4[/tex]

[tex]\Rightarrow m<1[/tex].

Hence, the condition for the expression [tex]x^2-2x+m[/tex] to have two different real roots is m<1.

Answer:

x= 3/2   and  4

Step-by-step explanation:

Use this method to solve;

First get the multiples of   12:    -1, -12   -2, -6    -3, -4 (we use negatives, because we need a positive 12, and a negative 11).

Next, set it up like this:  (2x - )   (x-  ).

Then plug in (2x-3)  and (x -4), and use rainbow to double check.

Then take 2x-3=0    and   x -4 =0 to get x.

2x-3=0, add 3 to both sides, leaving you with 2x=3, then divide by 2 to get x alone which leaves x= 3/2, could use 1.5 or 1 (1/2) too.

Then do the same with x-4=0, add 4 to both sides leaving x= 4.

Answers are x= 3/2   and 4.

1. 1/2 divided by 4 = 1/8 or 8.

2. 1 3/4 divided by 1/8 = 7/32.

Answer:

m∠R = 69

Step-by-step explanation:

m∠R + m∠S + m∠T = 180       {Angle sum property of triangle}

5x - 11 + 3x - 3 +  3x + 18 = 180

5x + 3x + 3x - 11 - 3 + 18 = 180     {Combine like terms}

                     11x  +4      = 180

                                 11x = 180 - 4

                                 11x = 176

                                    x = 176/11

x = 16

m∠R = 5x - 11

        = 5*16 - 11

        = 80 - 11

m∠R = 69
