Answer:

Time = 500 seconds  or 8.333 minutes

Step-by-step explanation:

Time = Distance/Speed

Speed of light = 3 x 10^8 meters/second

Distance=1.5 X 10^11 meters

Time = 1.5 X 10^11 meters/3 x 10^8 meters/second

We solve using the scientific notation. When 8 is taken to the top it is subtracted from 11 ( the base 10 is the same -- laws of exponents)

Dividing 1.5  by 3 gives 0.5 .

Time = 1.5 X 10^(11- 8) meters/3 meters/second

Time = 0.5 X 10^3 seconds

Time = 500 seconds

Dividng seconds with 60 will give minutes

Time= 500/60 = 8.333 minutes

Answer: a. -$12.71

b. $36.93

Step-by-step explanation:

Given data:

No of loss = 31

No of wins = 33

•Had to complete the question first,

Given that the price of the ticket at the beginning of the season = $49.64

the ticket price decrease = $0.41 for every loss

Solution:

a) The cost of the ticket decreases by $0.41 for every game loss.

Change in cost = -$0.41 × number of losses

= -$0.41 × 31

= -$12.71

b) The cost of a ticket for the next game given they have 31 losses is:

Cost of ticket = Initial cost of ticket + change in cost

= $49.64 - $12.71

= $36.93

Answer:

The answer is 166

Step-by-step explanation:

How you find the answer is easy, you just divide 3,000 by 18. So it will look like this: 3,000/18. Then, once you have that, put the equation into a calculator and you get 166.

The number of liters in a day is 4 liters.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, 3000 milliliters in 18 hours.

Here, in 1 hour number of milliliters

= 3000/18

= 166.7

We know that, 1 day = 24 hours

So, the number of milliliters in 24 hours is

166.7×24

= 4000.8 milliliters

As we know that, 1 liter = 1000 milliliters

Now, 4000.8 milliliters = 4000.8/1000

= 4.0008 liters

≈ 4 liters

Therefore, the number of liters in a day is 4 liters.

[tex]6z + 7 = 8z - 9[/tex]

[tex]8z - 9 = 6z + 7[/tex]

Add sides 9

[tex]8z - 9 + 9 = 6z + 7 + 9[/tex]

[tex]8z = 6z + 16[/tex]

Subtract sides 6z

[tex] - 6z + 8z = - 6z + 6z + 16[/tex]

[tex]2z = 16[/tex]

Divide sides by 2

[tex] \frac{2z}{2} = \frac{16}{2} \\ [/tex]

[tex]z = 8[/tex]

Thus ;

[tex]NP = 8z - 9[/tex]

[tex]NP = 8(8) - 9[/tex]

[tex]NP = 64 - 9[/tex]

[tex]NP = 64 - 4 - 5[/tex]

[tex]NP = 60 - 5[/tex]

[tex]NP = 55[/tex]

Answer: Sure,

Step-by-step explanation:

The form ax^2 + bx + c = 0 is called standard form of a quadratic equation. Before solving a quadratic equation using the Quadratic Formula, it's vital that you be sure the equation is in this form. If you don't, you might use the wrong values for a, b, or c, and then the formula will give incorrect solutions.

Answer: That is standard form.

[tex]\large\boxed{AB = 32.60 in}[/tex]

Find the length of AB by finding the length of its base:

We can use sine to solve for the length of the Hypotenuse of the triangle located in the base:

sin  = O / H

sin 50° = 24 / H

h * sin 50° = 24 ----> h = 24 / (sin 50°)

h ≈ 31.33 in

Use the Pythagorean Theorem to solve for the length of the diagonal since we have solved for the base of the triangle:

c² = a² + b²

c² = 31.33² + 9²

c² = 1062.57

c ≈ 32.60 in

AB = 32.60 in

Answer:

x=4

Step-by-step explanation:

Answer:

67.4

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. (x - 3)(x + 7) = 0

  By zero product property,

  (x - 3) = 0 ⇒ x = 3

  (x + 7) = 0 ⇒ x = -7

2. (2x + 6)(x - 7) = 0

   2(x + 3)(x - 7) = 0

   By zero product property,

   (x + 3) = 0 ⇒ x = -3

   (x - 7) = 0 ⇒ x = 7

3). (4x - 2)(x + 4) = 0

   2(2x - 1)(x + 4) = 0

   (2x - 1) = 0 ⇒ x = [tex]\frac{1}{2}[/tex]

   (x + 4) = 0 ⇒ x = -4

4. (5x - 1)(3x + 9) = 0

   3(5x - 1)(x + 3) = 0

   By zero product property,

   (5x - 1) = 0 ⇒ x = [tex]\frac{1}{5}[/tex]

   (x + 3) = 0 ⇒ x = -3

5. (x - 8)(x + 2) = 0

   By zero product property,

   (x - 8) = 0 ⇒ x = 8

   (x + 2) = 0 ⇒ x = -2

Answer:

49.5 meters of linen were left after the sale.

Step-by-step explanation:

Given that there are 100 meters of linen

And 15.75, 22.50 and 12.25 meters are sold.

This means that the sold linen has to be added  to find the total linen sold.

And then the quantity of sold linen will be subtracted from 100 to find the meters of linen left.

[tex]Total\ linen\ sold = 15.75+22.50+12.25 = 50.5\ meters[/tex]

Left linen will be:

[tex]=100-50.5 = 49.5[/tex]

Hence,

49.5 meters of linen were left after the sale.

Answer:

the difference is seven and the next answer should be 25 because 18+7=25

Answer:

25

Step-by-step explanation:

In order to find the answer to this question you must find the rule that the sequence goes by and then add.

You can see that it adds seven in order for it to reach four and then add's seven again to reach eleven meaning the rule of this sequence is plus seven.

So now just add:

[tex]18+7=25[/tex]

[tex]=25[/tex]
