Answer:

After 7 weeks from now you will have ​$185 in your bank​ account.

Step-by-step explanation:

We are given that you have ​$70 in your bank account. Each week you plan to deposit ​$7 from your allowance and ​$10 from your paycheck. The equation b = 70 + ​(10 + 7​)w gives the amount b in your account after w weeks.

The equation is given by;

b = 70 + (10 + 7)w

Now, in the question, it is given that you have ​$185 in your bank​ account, that means;

$185 = $70 + $17w

Finding the value of w(weeks);

$17w = $185 - $70

$17w = $115

w = [tex]\frac{\$115}{\$17}[/tex]

w = 6.76 weeks or 7 weeks (approx).

Hence, after 7 weeks from now you will have ​$185 in your bank​ account.

Answer:

x = 3

Step-by-step explanation:

Step 1: Write equation

3x - 10 + 4x = -2(x - 4) + 9

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

3(3) - 10 + 4(3) = -2(3 - 4) + 9

9 - 10 + 12 = -2(-1) + 9

-1 + 12 = 2 + 9

11 = 11

Answer:

The probability  is  [tex]P( p  >  0.585) =  0.044565  [/tex]

Step-by-step explanation:

From the question we are told that

   The population proportion is p =  0.50

   The sample size is n = 100

Gnerally the mean of the sampling distribution is  

          [tex]\mu_x =  0.50[/tex]

Generally the standard deviation of the sampling distribution is  

              [tex]\sigma  =  \sqrt{\frac{p(1- p)}{n} }[/tex]

=>            [tex]\sigma  =  \sqrt{\frac{0.5 (1- 0.5)}{100} }[/tex]

=>            [tex]\sigma  =0.05[/tex]

Generally the approximate probability that the cable company will keep the shopping channel

[tex]P( p  >  0.585) =  P(\frac{p- \mu_{x}}{\sigma }  > \frac{0.585 - 0.50}{0.05} )[/tex]

Generally  [tex]\frac{p- \mu_{x}}{\sigma } = Z (The  \  standardized \  value  \  of  p )[/tex]

=>  [tex]P( p  >  0.585) =  P(Z > 1.7 )[/tex]

From the z-table the probability of  (Z > 1.7 ) is  

       [tex]P(Z > 1.7 ) = 0.044565[/tex]

So [tex]P( p  >  0.585) =  0.044565  [/tex]

Answer:

The line on the right, closest to 1.

Step-by-step explanation:

We know since it is four thirds, that it is more than 1. That shows us it'll be at least on or over the 1 point.

Then we have one third, there's three points. Put it on the first point leading to 2.

Answer:

x = 2

Step-by-step explanation:

Step 1: Write equation

6 - 7x = 7x - 9x - 4

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

6 - 7(2) = 7(2) - 9(2) - 4

6 - 14 = 14 - 18 - 4

-8 = -4 - 4

-8 = -8

Answer:

168 cubic in.

Step-by-step explanation:

Volume of a rectangular pyramid: (l × w × h) / 3 or × 1/3.

Volume: (7 × 8 × 9) / 3

(504) /3

V = 168 cubic in.

Answer:III/ 0.98

Step-by-step explanation: if you multiply a number by a decimal (not like 1.55, since that would increase the value since there is a whole) it will decrease.

Answer:

0.98

Step-by-step explanation:

because if you do 6 x 0.98 you get 5.88

Answer:

3(x+4)=36 is the same as 3x+12=36

If 3x+12=36, that means x=8

36-12= 24

Step-by-step explanation:

Answer:

a exactly one

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given the equations:

4c-d = f  ....... 1

d = c-e....... 2

f = d + e....... 3

Substitute 2 into 1

4c -(c-e) = f

4c -c + e =f

3c + e = f ......4

Substitute equation 3 into 4:

3c+e = d+e

subtract e from both sides

3c+e-e = d+e-e

3c = c (Proved)

Answer:

83

Step-by-step explanation:

All sides of a triangle combined equal 180 so you would add the values you have and then subtract it from 180

Step-by-step explanation:

We know that:-

All angles of a triangle sum up to give 180°.

So, According to Question,

[tex]20 + 87 + x = 180[/tex]

[tex]107 + x = 180[/tex]

[tex]x = 180 - 107[/tex]

[tex]x = 73[/tex]

So, x = 73° is the answer.

Hope it helps :)
