Answer: 400

Step-by-step explanation:

By solving a system of equations we will see that the charge on the first city was $5,000, and on the second city, $4,000.

Let's define the variables:

We know that:

C₂ = C₁ - $1000

And we also know that the total tax is $455, then we can write:

0.035*C₁ + 0.07*C₂ = $455

(this says that the total tax is $455)

So we have a system of equations:

C₂ = C₁ - $1000

0.035*C₁ + 0.07*C₂ = $455

We can replace the first one into the second to get:

0.035*C₁ + 0.07*(C₁ - $1000) = $455

0.105*C₁ - $70 = $455

C₁ = ($455 + $70)/0.105 = $5,000

And:

C₂ = C₁ - $1000 = $5,000 - $1,000 = $4,000

The charge in the first city is $5,000 and in the second city was $4,000.

The equation of the line that goes through the point (1, -1) and has a slope of 5 is y = 5x - 6

The linear equation of a line is represented as follows:

y = mx + b

where

Therefore, the line passes through (1, -1) and has a slope of 5.

Using the model y = mx + b,

y = 5x + b

let's find b using (1, -1)

- 1 = 5(1) + b

-1 - 5 = b

b = -6

Therefore, the equation of the line that goes through the point (1, -1) and has a slope of 5 is y = 5x - 6

Answer:

y=5x-1

Step-by-step explanation:

Slope is represented as m. y-intercept is represented as b. And ordered pairs are written in the form x,y. So you ignore the first 1 in your ordered pairs and just look at the second one because the second one represents the y-intercept.

Answer:

x = 4, y = 2

Step-by-step explanation:

y = 6 - x

y = x - 2

Substitute the value for y in the first equation into the second.

So we get:

6 - x = x - 2

-x - x = -2 -6

-2x = -8

x = 4

Plug this into second equation:

y = 4 - 2 = 2.

Check these results in equation 1:

y = 6 - x

2 = 6 - 4 = 2

- so correct.

The probability that Aiko drives without seeing a red light is the likelihood of not seeing the red light

The odds against Aiko driving to work without seeing a red light is 7 : 1

The probability of not having to stop at a red light is given as:

P(Not Stop) = 0.125

The probability that he would stop at a traffic light is calculated using:

P(Stop) = 1  - 0.125

Evaluate

P(Stop) = 0.875

The odds against Aiko driving to work without seeing a red light is calculated using:

Odd = P(Stop) : P(Not stop)

So, we have:

Odd = 0.875 : 0.125

Simplify

Odd = 7 : 1

Hence, the odds against Aiko driving to work without seeing a red light is 7 : 1

Answer:

90 boxes

Step-by-step explanation:

you will have to divide the total amount you have by the groups they will go into. in this case it is 5400/60 = 90

Answer:

radius r = 12 m

height h = 5 m

slant height s = 13 m

volume V = 753.982237 m ³

lateral surface area L = 490.088454 m²

base surface area B = 452.389342 m²

total surface area A = 942.477796 m²

The total surface area of cone is 942 cm².

Total surface area is the sum of the area of the circular base and the area of the curved part of the cone.

The total surface area of a cone is the sum of the area of the base and the lateral area:

  SA = πr² + πrl

where, r is radius

           l is slant height

Now, for finding the slant height of the given cone is

         l² = r² + h²

         l² = 12² + 5²

         l² = 144 + 25

        l² = 169

        l = 13 cm

Now, SA = π X 12² + π X 12 X 13

              = 144π + 156π

              = 300π

              = 300 X 3.14

              = 942 cm²

Thus, the total surface area of cone is 942 cm².

Answer:

Since the vertex is the tallest or shortest point on the graph, the vertex would be 8 since 8 is the tallest point. So it would be B. 8

Step-by-step explanation:

Answer:

(0, 4 )

Step-by-step explanation:

5x + 2y = 8 → (1)

- 4x + 10y = 40 → (2)

multiplying (1) by - 5 and adding to (2) will eliminate y

- 25x - 10y = - 40 → (3)

add (2) and (3) term by term to eliminate y

- 29x = 0 , then

x = 0

substitute x = 0 into (1) and solve for y

5(0) + 2y = 8

0 + 2y = 8

2y = 8 ( divide both sides by 2 )

y = 4

solution is (0, 4 )

Geometric sequence formula:  [tex]a_n=ar^{n-1}[/tex]

Given:

Find common ratio (r):

[tex]\begin{aligned}\implies \dfrac{a_{28}}{a_{23}} =\dfrac{ar^{27}}{ar^{22}} & =\dfrac{24}{16}\\ \implies r^5 & =\dfrac32\\ \implies r & = \sqrt[5]{\frac32} \end{aligned}[/tex]

Find initial term (a):

[tex]\implies ar^{22}=16[/tex]

[tex]\implies a(\sqrt[5]{\frac32} )^{22}=16[/tex]

[tex]\implies a(\frac32} )^{\frac{22}{5}}=16[/tex]

[tex]\implies a=\dfrac{16}{(\frac32)^{\frac{22}{5}}}[/tex]

Find the 43rd term:

[tex]\implies a_{43}=ar^{42}[/tex]

[tex]\implies a_{43}= \left(\dfrac{16}{(\frac32)^{\frac{22}{5}}}\right)(\sqrt[5]{\frac32} )^{42}[/tex]

[tex]\implies a_{43}=16 \cdot (\frac32)^{-\frac{22}{5}} \cdot (\frac32)^{\frac{42}{5}}[/tex]

[tex]\implies a_{43}=16 \cdot (\frac32)^4[/tex]

[tex]\implies a_{43}=16 \cdot \left(\dfrac{3^4}{2^4}\right)[/tex]

Choice J

[tex]-8 + (-7) = -7-8[/tex]

Answer:

The answer is Option J

Step-by-step explanation:

(-8) + (-7) = (-8) – 7 = (-15)

(F) (-8) – (-7) = (-8) + 7 = (-1)

(G) (-8) + 7 = (-1)

(H) (-7) – (-8) = (-7) + 8 = 1

(J) (-7) – 8 = (-15)

Thus, Option (J) has the same value as (-8) + (-7).

The total remaining bank balance in the account of Omar after reducing all the debit and adding the paycheck is $761.25.

The money which is paid from an account is called the debit amount and the money which is paid into an account is called the credit amount.

To know the remaining balance of the account, all the debit amount is subtracted from it and all the credit amount is added to it.

The data given in the table is,

Pharmacy       - $15.20-Debited

Rent                - $425.00-Debited

Dinner             - $22.30-Debited

Movie Ticket  - $26.70-Debited

Pay Check     - $1015.50-Credited

Initial Balance- $219.80

The initial balance is $219.80, and a paycheck of $1015.50 is credited to his account. Thus, the total balance in his account without any debit is,

[tex]\rm A_i=1015.50+219.80\\\\A_i=1253.30[/tex]

The total amount debited from their account of Omar is,

[tex]\rm A_d=15.20+425+22.30+26.70\\\\A_d=474.05[/tex]

Thus, the total remaining amount in his account is,

[tex]\rm A= 1253.3-474.05\\\\A=761.25[/tex]

Hence, the total remaining bank balance in the account of Omar after reducing all the debit and adding the paycheck is $761.25.
