Answer:

36.5

Step-by-step explanation:

255.5/7 = 36.5

Answer:

See answers below

Step-by-step explanation:

1) Given the simultaneous equation;

-2x + 2y = 2 .... 1  * 2

4x –4y= 4...2 * 1

____________

-4x + 4y = 4 .... 1

4x –4y= 4...2

Add both equations

4y-4y = 4-4

0y = 0

y = 0/0

Let x = k

Substitute x = k into 1

From 1: -2x + 2y = 2

-x+y = 1

-k + y = 1

y = 1+k

Hence the solution to the system of equation (x, y) is (k, 1 + k) where k is any integer.

The presence of k shows that the equation has many solutions since k can take any value

2) Let a box of popcorn be x

Let the cost of a drink be y

If a customer at a concession stand bought 2 boxes of popcorn and 3 drinks for $12, then;

2x + 3y = 12 ... 1

Also, if another customer bought 3 boxes of popcorn and 5 drinks for $19, then;

3x + 5y = 19 ...2

Solve 1 and 2 simultaneously

2x + 3y = 12 ... 1  * 3

3x + 5y = 19 ...2  * 2

_________________

6x + 9y = 36  

6x + 10y = 38

Subtract

9y - 10y = 36 - 38

-y = -2

y = 2

Recall that 2x + 3y = 12

2x + 3(2) = 12

2x + 6 = 12

2x = 12-6

2x = 6

x = 6/2

x= 3

Hence a box of popcorn cost $3 and a drink cost $2

Here is the full question

There are seven nickels and seven dimes in your pocket. You randomly pick a coin out of your pocket and place it on a counter. Then you randomly pick another coin. Find the probability that both coins are nickels.

Because there is no replacement, after you pick the first coin, the number of coins in your pocket becomes 13 and the number of nickels in your pocket becomes 6

probability that both coins are nickels = probability that the first coin is a nickel x probability second coin is a nickel

Answer:

Step-by-step explanation:

Determine the perpendicular bisector of AB:

Slope of AB = (12-6)/(4-14) = -0.6

Midpoint of AB: ((4+14)/2, (12+6)/2) = (9, 9)

Perpendicular bisector: y = -0.6x + 14.4

Determine the perpendicular bisector of AC:

Slope of AC = (12-2)/(4+6) = 1

Midpoint of AC: ((4-6)/2, (12+2)/2) = (-1, 7)

Perpendicular bisector: y = x + 8

Circumcenter is the intersection of the perpendicular bisectors.

x + 8 = -0.6x + 14.4

1.6x = 6.4

x = 4

y = x + 8 = 12

Answer:

Yes

Step-by-step explanation:

It is given that a prism is built that have a volume of 36.

Now if the prism is rebuild with either centimeter cubes or the inch cubes or foot cubes will have the same volume of 36 as the volume here is constant. The centimeter cubes used to build the prism will be smaller in size and will require more of the cubes to build the cube for a volume of 36.

Similarly, if we take inch cubes or the foot cubes, to build a prism having a volume of 36, we need to take less number of the cubes accordingly.

Step-by-step explanation:

Answer: 10 miles

Step-by-step explanation:

You can set this up as an equation where x will represent the number of miles charged. So if we know how much the pick up fee is, how much it is per mile and the total charge we can set up the equation as follows:

3.20 + 3x = 33.20

If we solve for x we will find out how many miles she traveled. So to do so we need to get x on one side and the other numbers on the other side of the equal sign. So to begin we'll subtract 3.20 from both sides:

3x = 30.00

and then divide both sides by 3:

x = 10

So she traveled 10 miles.

The Taxi ride was 10 miles.

An equation is an expression that shows the relationship between two or more numbers and variables.

We can set an equation where x will represent the number of miles charged. So, the total charge we can set up the equation as follows:

3.20 + 3x = 33.20

If we solve for x we will find out the miles she traveled.

Then subtract 3.20 from both sides:

3x = 30.00

then divide both sides by 3;

x = 10

Therefore, she traveled 10 miles.

Answer:

Step-by-step explanation:

Using the sine ratio in the right triangle

sin? = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{13}{17}[/tex] , then

? = [tex]sin^{-1}[/tex] ([tex]\frac{13}{17}[/tex] ) ≈ 49.9° ( to the nearest tenth )

Using the cosine ratio in the right triangle

Answer:

New price of the ball after discount = $16.65

Step-by-step explanation:

Selling price of the soccer ball = $45

Discount labeled on the ball = 63% off

Therefore, selling price after the discount = Original selling price - %discount

= $45 - (63% of $45)

= $45 - $28.35

= $16.65

New price of the ball after discount = $16.65

Answer:

8°

Step-by-step explanation:

The sum of the measures of the exterior angles of a any polygon = 360.

So,  x + 2x + 4x + 5x + 6x + 8x + 9x + 10x = 360

        45x = 360

            x = 8°

The measure of the smallest exterior angle would be equal to 8°

In geometry, a Octagon is a eight - sided polygon. For a [n] sided polygon -

According to the question, we have - A Octagon and the measures of the exterior angles of an octagon are x°, 2x°, 4x°, 5x°, 6x°, 8x°, 9x° and 10x°.

The sum of the exterior angles of the octagon will be 360°.

Therefore, we can write -

x + 2x + 4x + 5x + 6x + 8x + 9x + 10x = 360°

45x = 360°

x = 360/45

x = 8

The smallest exterior angle would be equal to [x]° = 8°

Therefore, the measure of the smallest exterior angle would be equal to 8°
