Answer:

Car A: Initial Charge = 20

Car B: Initial Charge = 30

Car A: Rate = 5

Car B: Rate = 0

At 2 miles, their charges will be the same

Step-by-step explanation:

Given

Car A

[tex]Base\ Charge = \$20[/tex]

[tex]Rate = \$5[/tex] per mile

Car B

[tex]Base\ Charge = \$30[/tex]

Solving (a): The initial charge

First, we get the  linear equation that represents both car's charges.

Represent number of miles with m.

So, the charges is:

Car A

[tex]A = Base\ Charge + Rate * m[/tex]

[tex]A = 20 + 5 * m[/tex]

[tex]A = 20 + 5m[/tex]

Set m to 0 to get the initial charge:

[tex]A = 20 + 5*0[/tex]

[tex]A=20[/tex]

and

[tex]Rate = 5[/tex]

Car B:

[tex]B = Base\ Charge + 0 * m[/tex] i.e. Rate is 0

[tex]B = 30+ 0 * m[/tex]

[tex]B = 30[/tex]

So:

[tex]Initial = 30[/tex] and [tex]Rate = 0[/tex]

Solving (b): When their charge wil be equal.

To do this, we set:

[tex]A = B[/tex]

[tex]20 + 5m = 30[/tex]

[tex]5m = 30- 20[/tex]

[tex]5m = 10[/tex]

[tex]m = 2[/tex]

At 2 miles, their charges will be equal

Answer:

UCL (X-bar) = X mean+ (A2 x R-bar)

LCL (X-bar) = X mean -(A2 x R-bar)

Center line = Mean

A2 for sample size of 10 = 0.308

X mean = 45.343019

R bar = Average of range = 0.0076382

UCL (X-bar) =45.343019+(0.308*0.0076382) = 45.3453715656 grams

LCL (X-bar) = 45.343019-(0.308*0.0076382) = 45.3406664344 grams

Center line = Mean = 45.343019

Answer:

Option B = 25.5 ft

Step-by-step explanation:

Circumference = 80 ft

C = 2πr

80 = 2 * (22/7) * r

80 = (44/ 7) *  r

So, Radius (r) = 80 * (7/44)

        = 12.72 Feet

--> Diameter = 2r = 2 * 12.72    

= 25.45 Feet

Therefore, Answer = Option B = 25.5 Feet (Round off)

oh wait I'm bad - ignore this first answer lol - I didn't read the part that says cutting 4 in. squares off the corners

Here's my previous one if you wanna see it though:

Answer:

A = 1280 in²

Step-by-step explanation:  

We know that the volume of a cube is A = a³, where a is the length of one of the edges.  

So, to find a:  

a³ = 4096

a = ∛4096  

a = 16 in

Now, we need to find the surface area of the square on the cube, where:

A = 6a², because we are making a box (that is empty inside).  

However, we need to change the formula to:

A = 5a², because the problem says that there is no top (so there are only 5 squares)

A = 5(16)²

A = 1280 in²

For the given triangle the statement that is true for length x is -

x < 9

What are triangles?

Triangles are a particular sort of polygon in geometry that have three sides and three vertices. Three straight sides make up the two-dimensional figure shown here. An example of a 3-sided polygon is a triangle. The total of a triangle's three angles equals 180 degrees. One plane completely encloses the triangle.

The length of 1 side is = 5 units

The length of second side is = 4 units

A key geometrical concept that connects the lengths of a triangle's sides is the triangle inequality theorem.

It stipulates that the length of the remaining side must be greater than the sum of the lengths of any two sides of a triangle.

The triangle inequality theorem can be written out as follows if a, b, and c are the lengths of a triangle's sides:

b + c > a

a + c > b

b + a > c

Since the sum for the given triangle is 5 + 4 = 9

So, the third side must be less than 9.

Therefore, the inequality is x < 9.

Answer:

(-1,5)

Step-by-step explanation:

Solve the following system:

2 y + x = 9 | (equation 1)

2 y + 3 x = 7 | (equation 2)  

Subtract equation 2 from equation 1:

( 2 y + x ) - ( 2 y + 3 x ) = 9 - 7

- 2 x = 2

x = - 1

Substitute into question 1:

2 y - 1 = 9

y = 5

Answer: x = -1 , y = 5

Step-by-step explanation:

You need to find the highest common factor (2 in this case).

When the word factorise is mentioned that means there has to be brackets in your answer.

Answer:

13.4%

Step-by-step explanation:

First year:

$10,000*6% = $600

New balance = $10,600

Second Year:

$10,600*7% = $742

$10,600+ $742 = $11,342

Total Return:

Final Balance - Initial balance

$11,342 - $10,000 = $1,342

$10,000*x ÷ $1,342

x = $1,342/$10,000

x = 0.1342

0.134 = 13.4%
