Tell how much each person gets when they share equally.



6 people share 12 muffins.

Answer:

x² + 6x + 9

Step-by-step explanation:

(x + 3)² = (x + 3)(x + 3)

Each term in the second factor is multiplied by each term in the first factor , that is

x(x + 3) + 3(x + 3) ← distribute parenthesis

= x² + 3x + 3x + 9 ← collect like terms

= x² + 6x + 9

Answer:

In y = kx, where k is the constant of proportionality.

Answer:

k is the constant

Step-by-step explanation:

Direct variation is simply explained as when a number is directly proportional to another number. For example, when 8 is directly proportional to 4 then it will result to

=> 8= k4, where k is the constant

=> divide both sides by 4 to get k

=> k= 2

D: PQ is congruent to QR

Step-by-step explanation:

In a rectangle, there are a few statements that are always true. Opposite sides are congruent and parallel and all angles meet at 90 degrees. However, adjacent sides (sides that are touching/share a vertex) are not necessarily congruent. They can be; if they are then that rectangle is a square. Nevertheless, if adjacent sides are not congruent, then it is still a rectangle, so long as they meet at a right angle.

This is the required answer!

Answer:

-21

Step-by-step explanation:

the y intercept is when x=0.

you can see that this is a linear equation where each increase in x results in  an increase of 4 onto the y value.

so if when x=1, y=-17, subtract 4 to find what y equals when x is 0.

-17 -4=-21

The expected number of female children in a family with three children is 1.5.

The correct option is B.

We have to determine

What is the expected number of female children in a family with three children?

Probability is defined as the sum of all observations and the number of observations.

The expected value of female children= Probability of female children x Total number of children.

A child can be male or female, so there are 2 combinations, the favorable outcome is female.

The probability of female children = 1/2.

Therefore,

The expected number of female children in a family with three children is;

[tex]= \dfrac{1}{2}\times 3\\\\=1.5[/tex]

Hence, The expected number of female children in a family with three children is 1.5.

Answer:

x=13.243568

Step-by-step explanation:

1000=58.3x+227.9

Step 1: Flip the equation.

58.3x+227.9=1000

Step 2: Subtract 227.9 from both sides.

58.3x+227.9=1000

         −227.9   −227.9

58.3x=772.1

Step 3: Divide both sides by 58.3

58.3x/58.3 = 772.1/58.3

x=13.243568

This is wrong because the difference of x and 4.5 that is (x- 4.5) is negative two times that is -2(x -4.5). Then the correct option is C.

BODMAS rule means for the Bracket, Order, Division, Multiplication, Addition, and Subtraction.

Emma read the statement "the quotient of six and a number, x, is the same as negative two times the difference of x and 4. 5. " She translated it as shown below.

[tex]\rm 6 x = -2 x - 4. 5[/tex]

This is wrong because the difference of x and 4.5 that is (x- 4.5) is negative two times that is -2(x -4.5).

Thus, She should have used parentheses to show that Negative 2 is multiplied by (x minus 4. 5). Then the correct option is C.

Step-by-step explanation:

I think you mean the circles

x² + y² = 4

(x - 2)² + (y - 2)² = 4

Notice that both have radius 2, but the first one is centered at the origin (0, 0) while the second one is centered at (2, 2). The two circles intersect at the points (2, 0) and (0, 2), which means the bounded region between them is contained entirely in the first quadrant.

If we solve both equations above for y, we would find two solutions in each case:

x² + y² = 4   ⇒   y = ± √(4 - x²)

(x - 2)² + (y - 2)² = 4   ⇒   y = 2 ± √(4 - (x - 2)²)

The positive/negative root corresponds to the upper/lower semicircle the make up the full circle. The semicircles we're interested in are

y = + √(4 - x²)

y = 2 - √(4 - (x - 2)²)

that is, the upper half of the circle centered at the origin, and the lower half of the circle centered at (2, 2).

So, in standard Cartesian coordinates, the bounded region (call it R) is the set

[tex]R = \left\{(x, y) : 0 \le x \le 2 \text{ and } 2-\sqrt{4-(x-2)^2} \le y \le \sqrt{4-x^2} \right\}[/tex]

and the area is given by the double integral

The horizontal velocity of the cannonball is released at an angle of 20˚ at a velocity of 12m/s is 11.276 m/s.

Velocity is the rate of change of position with respect to time. It is a scalar quantity.

We know that the velocity is a scalar quantity therefore, it can be divided into two components such that the first component is the vertical component which is equal to the (V sinθ), while the other component is the horizontal component(V cosθ), where V is the velocity and θ is the angle of the velocity from the positive x-axis.

Now, in order to calculate the horizontal velocity of the cannonball we can write,

[tex]\rm V_x = V\ Cos\theta[/tex]

[tex]V_x = 12 (Cos\ 20^o)\\\\V_x = 11.276\rm\ m/s[/tex]

Hence, the horizontal velocity of the cannonball is released at an angle of 20˚ at a velocity of 12m/s is 11.276 m/s.

11. It will take about 26 minutes to install a singular tile.

12. It will take about 10 more minutes to install a light than it does to install a cable.

Step-by-step explanation:

11. Since installing 15 new tiles took a total of 390 minutes and each tile took the same amount of time, you can divide the total amount of time by the number of tiles.

390/15= 26 minutes

It will take about 26 minutes to install a single tile.

12. By looking at the chart it can be assumed that installing a light takes about 22 minutes since it is in the middle of 20 and 24 minutes. Installing a cable only takes 12 minutes.

22-12= 10 minutes

It takes about 10 minutes longer to install a light than it does a cable.

It took about 26 minutes to install a single tile and 10 minutes longer to install a light than it does a cable.

Answer:

$31950

Step-by-step explanation:

We multiply 30,000 by .065 to get 1950. We ad them together to get $31,950. :)

Answer:

$31,950 dollars

Step-by-step explanation:

Given the following question:
Initial price of the car is $30,000...
The car has an increase tax of 6.5% (which means 6.5% of the initial price of the car is the sales tax.)

In order to find the total cost of the car, we need to find 6.5% of $30,000 and then add that number to the initial price to have the answer.

[tex]\frac{6.5\times30000}{100} =6.5\times30000=19500\div100=1950[/tex]
[tex]30000+1950=31950[/tex]

Therefore, the car has the total cost (including tax) of "$31,950 dollars."
