Answer:

the answer is 77

Step-by-step explanation:

a= b+c/2

78+76/2 = 77

Answer:

we have two equations:

2*x + y = 20

y = a + 18/x - 3

We want to find the values of a such that the graphs of the equations do not intersect.

The first step is to isolate y in the first equation.

now we get:

y = 20 - 2*x

Then we have the system of equations:

y = 20 - 2*x

y = a + 18/x - 3

If the line intersects the curve at a point (x, y), then at that point both functions have the same value of y, then:

20 - 2*x = y = a + 18/x- 3

We want to find a value of such that this does not happen.

Let's solve that equation and see what we can find.

20 - 2*x =  a + 18/x - 3

20 + 3 = a + 18/x + 2*x

23 = a + 18/x + 2*x

(23 - a) = 18/x + 2*x

if we multiply all values by x, we get:

(23 - a)*x = 18 + 2*x^2

Then we have a quadratic equation, we can write this as:

2*x^2 - (23 - a)*x + 18 = 0

Now, remember that if the determinant of the quadratic function is smaller than zero, then the function does not have any real solution, then we need to find a such that the determinant of this quadratic equation is smaller than zero.

Remember that for a quadratic equation:

a*x^2 + b*x + c = 0 is:

b^2 - 4*a*c

In this case, the determinant is:

(-(23 - a))^2 - 4*2*18

(23 - a)^2 - 144

And this must be smaller than zero, then:

(23 - a)^2 - 144 < 0

23^2 - 2*23*a + a^2 - 144 < 0

529 - 46*a + a^2 - 144 < 0

a^2 - 46*a + 385 < 0

Notice that the function has a positive leading coefficient, then the arms of the function go upwards, then the region of the function that is smaller than zero is the values of a that are between both roots of a.

Then we need to solve:

a^2 - 46*a + 385 = 0

We can use the Bhaskara's equation to find the roots, the roots are given by:

[tex]a = \frac{-(-46) +- \sqrt{(-46)^2 - 4*1*385} }{2*1} = \frac{46 +-24}{2}[/tex]

Then the two roots are:

a₁ = (46 + 24)/2 = 35

a₂ = (46 - 24)/2 = 11

Then for all the values of a suc that:

11 < a < 35

The line does not intersect the curve.

Answer:

0.40m/s^2

Step-by-step explanation:

Given data

Mass= 133.5kg

Force F= 54.5N

The expression for the force acting is

F=ma

substitute

54.5=133.5*a

]Divide both sides by 133.5

a= 54.5/133.5

a= 0.40 m/s^2

Hence the acceleration is 0.40m/s^2

Step-by-step explanation:

The points form a right triangle. The circumcenter is the midpoint of the hypotenuse of a right triangle. Here, that is the midpoint of AC:

  O = (A +C)/2

  O = ((1, 1) +(10, 8))/2 = (11, 9)/2 = (5.5, 4.5)

The circumcenter is (5.5, 4.5).

Answer:70

Step-by-step explanation:

The cost of booking was $100 as obtained by the length of the show.

A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.

Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.

An example of a non-linear function is a quadratic function.

From the given information the two linear equations can be formed as,

30x + 40 and 35x + 30.

The cost would be the same when we'll equate these two equations.

30x + 40 = 35x + 30.

30x - 35x = 30 - 40.

- 5x = - 10.

5x = 10.

x = 10/5.

x = 2, So at two hours the cost would be the same and the total cost is,

$30(2) + 40.

$60 + 40.

= $100.

The total cost will cost be the same at each shop for 60 pictures.

Word problems are often described verbally as instances where a problem exists and one or more questions are posed, the solutions to which can be found by applying mathematical operations to the numerical information provided in the problem statement.

Let for x number of picture, the total cost will cost be the same at each shop.

Total cost of x number of picture on Photos fast shop = $ (2.50 + 0.05x)

Total cost of x number of picture on Photos quick shop =  $ (3.70 + 0.03x)

according to the question:

(2.50 + 0.05x) = (3.70 + 0.03x)

0.05x - 0.03x = 3.70 - 2.50

0.02x = 1.20

x = 1.20 ÷ 0.02

x = 60

Hence, for 60 number of picture, the total cost will cost be the same at each shop.

  slope: 9/5

  graph: C

Step-by-step explanation:

In a proportional relationship, the slope is the ratio of y to x. Here, that is ...

  slope = y/x = 9/5

__

The graph of a proportional relationship goes through the origin. (eliminates graph B)

For this relationship, y is greater than x. (eliminates graph A)

The appropriate graph for y = 9/5x is graph C.

Answer:

22 cubes are formed.

Step-by-step explanation:

Given that,

The diameter of the cylinder, d = 14 cm

Height of the cylinder, h = 49 cm

The side of the cube, a = 7 cm

Let there are n cubes formed. So,

[tex]n=\dfrac{\text{volume of cylinder}}{\text{side of cube}^3}\\\\=\dfrac{\pi r^2 h}{a^3}\\\\=\dfrac{\dfrac{22}{7}\times (7)^2 \times 49}{(7)^3}\\\\n=22[/tex]

Hence, there are 22 cubes that are formed.

Answer:

Coefficient. For example, in the term -3x, -3 serves as the coefficient of x.

The number in front of a variable or term is called a coefficient.

The coefficient represents the numerical factor by which the variable or term is multiplied. In an algebraic expression, the coefficient is the number that appears directly in front of the variable.

For example, in the expression 5x, the coefficient of x is 5. Similarly, in the expression 3y², the coefficient of y² is 3. The coefficient helps determine the magnitude or scale of the variable or term within the expression.

Therefore, the number in front of a variable or term is called a coefficient.

16498 + 7568 = 24066.So, the correct answer is 24066 To find 7568 more than 16498, we can perform the following calculation:

16498 + 7568 = 24066.

We can perform sum via many ways:

Place value: This approach adds numbers by using their place values. For instance, we would arrange the numbers according to their decimal places and add each place value column separately to get the sum of 23 and 45. 68 would be the total.

Comparable to place value addition, but with the integers arranged in columns, is the column addition technique. For adding higher numbers, this can be useful. For instance, we would arrange the numbers in columns and add each column separately to equal 234 + 567. 801 would be the total.

Mental addition: To add numbers quickly, utilize this technique. For instance, we may consider about 23 as 20 + 3 and 45 as 40 to add 23 and 45.
