The number of  used games consoles is 9 and the number of new game consoles is 5

Here we use the Linear equation method to solve the problem. Since we don't know the number games, represent them with variables x and y.

Now for two linear equations according to the conditions as given in the problem. Solve the equations for the values of both x and y by using the substitution method.

Here we have

An electronics store sells used game consoles for $79.00 and new ones for $149.00

Let 'x' and 'y' be the number of used and new game consoles respectively

Cost of 'x' used games consoles = 79x

Cost of 'y' new game consoles = 149y

Given total profit =$ 1456    

=> 79x + 149y = 1456 ----- (1)

The total number of game consoles = 14

=> x + y = 14

=> x = 14 - y ---- (2)

Substitute (2) in (1)

=> 79(14 - y)  + 149y = 1456

=> 1104 - 79y + 149y = 1456

=> 70y = 350

=> y = 5

From (2) => x = 14 - 5 = 9

Therefore,

The number of  used games consoles is 9 and the number of new game consoles is 5

If y*=y1/2(y2+1) then -3(16* - 9*) = -10.5y1(y2 + 1), called polynomial.

A polynomial is an expression that consists of variables, numbers, and operations (like addition, subtraction, multiplication, and division). It is similar to a mathematical equation, but instead of an equals sign, it uses coefficients and variables in a power form. The power of a polynomial is determined by the highest power of the variables in the expression.

For example, if the polynomial is x2 + 5x + 2, then the power is 2. Polynomials are used in many areas of mathematics, such as calculus, algebra, and number theory.

If y*= y1/2(y2+1) then -3(16* - 9*)

= -3(16(y1/2(y2 + 1)) - 9(y1/2(y2 + 1)))

= -3(8y1(y2 + 1) - 4.5y1(y2 + 1))

= -3(3.5y1(y2 + 1))

= -10.5y1(y2 + 1)

In this problem, 16* is equal to 16(y1/2(y2 + 1)) and 9* is equal to 9(y1/2(y2 + 1)). When -3 is multiplied to 16* - 9*, the result is -3 times the difference of 16* and 9*. The expression then simplifies to -10.5y1(y2 + 1).

The geometric mean of two numbers is the square root of their product. Hence, the geometric mean 'a' of 2 and 1/4 is approximately equal to 0.70710678118.

Recall that the geometric mean of two numbers is the square root of their product. This means that we need to multiply the two numbers (2 and 1/4) and then take the square root of the result.

Multiply 2 and 1/4:

2 × 1/4 = 1/2

Take the square root of the result:

a = √(1/2)

Simplify the square root:

a = √(1/2) = √(1)/√(2) = 1/√(2)

Rationalize the denominator by multiplying the top and bottom by √(2):

a = (1/√(2)) × (√(2)/√(2)) = √(2)/2

Approximate the result to a desired level of accuracy, if necessary. In this case, rounding to 11 decimal places gives:

a ≈ 0.70710678118

Therefore, the geometric mean 'a' of 2 and 1/4 is approximately equal to 0.70710678118

the equation of the line will be 5y = 7x -7. Option c is correct.

A linear equation is an algebraic equation of the form y = mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given, a linear equation that passes through the points (5,0) and (0, -7)

The slope-intercept form of the equation of a line

where m is the slope

b is the y-intercept

since, slope = (y - y')/(x -x')

In our case,

slope = (-7 -0)/(0-5)

slope = 7/5

b = -7

thus,

the equation of the line will be:

In the given question, the rocket will hit the ground in 7 seconds. The width of the rectangle is 3 cm. Kirk makes the wall in 5.5 hours. The student needs 97 marks.

The relation between the height and the time of the toy rocket has been given in the question as,

h = -4.9t²+33.6t + 4.9

where,

h= height of the rocket after getting launched

t= time after which the rocket has been launched

So, if we have to calculate how much time the rocket takes to reach the ground,

we have to take h=0 (at ground).

So, the equation becomes

0 = -4.9t²+33.6t + 4.9

Now, the roots of this equation will give the time at which the rocket will hit the ground.

So, after calculating we get

t = -0.1428 sec

or

t = 7 sec

since negative time is not possible,

the time at which the rocket will hit the ground is 7 seconds.

The length of the rectangle is = 5b-7 cm

Hence, the area is = b(5b-7) = 24

Hence, the width comes out to be = 3 cm

Kirk would be able to make the wall in 5.5 hours. This is because Jeff can make it one hour earlier than him i.e., K-1 hours. So, we get -

= (K-1) + K = 10

= 2K = 11

= K = 5.5 hours

Viola has covered a horizontal distance of 199.7 meters when driving 200 meters up a hill that makes an angle of 3 degrees with the horizontal.

Viola drives 200 meters up a hill that makes an angle of 3 degrees with the horizontal. To find the horizontal distance she covered, we can use the cosine formula:

Cos(θ) = adjacent/hypotenuse

In this case, the adjacent side is the horizontal distance we are trying to find, the hypotenuse is the distance she drove (200 meters), and the angle is 3 degrees. Plugging in these values, we get:

Cos(3º) = adjacent/200

Rearranging the equation to solve for the adjacent side, we get:

adjacent = 200*cos(3)

Using a calculator, we find that cos(3) is approximately 0.9986. Multiplying this by 200 gives us:

adjacent = 199.72

Therefore, the horizontal distance that Viola covered is approximately 199.72 meters.

Therefore, the equations that represent circles with a diameter of 12 units and a center on the y-axis are: x² + (y - 3)²=36 and x² + (y + 8)²=36.

In mathematics, an equation is a statement that asserts the equality of two expressions. It consists of two expressions separated by an equals sign (=). The expression on the left side of the equals sign is called the left-hand side (LHS), and the expression on the right side of the equals sign is called the right-hand side (RHS). Solving an equation means finding the value of the variable that makes the equation true. I

Here,

A circle with diameter 12 units and center on the y-axis has its center at (0, c), where c is a constant. The radius of the circle is half the diameter, which is 6 units.

The equation of a circle with center (0, c) and radius r is given by:

x² + (y - c)² = r²

Substituting r = 6 and simplifying, we get:

x² + (y - c)² = 36

If Kennedi has half a bag of dog food left and she has 5 puppies to feed, then each puppy will receive 1/5th of the remaining dog food.

To calculate this, you can divide the remaining dog food (which is half a bag) by the number of puppies (which is 5):

1/2 bag of dog food ÷ 5 puppies = 1/10 bag of dog food per puppy
