Answer:

a). Distance round one loop = 141.37 meters

b). Distance covered = 3534.29 meters

Step-by-step explanation:

Diameter of the given track = 45 meters

a). Distance round one loop of the track = circumference of the circle

    Circumference of a circle = π × (Diameter)

                                               = π × (45)

                                               = 141.37 meters

b). Distance covered by going around the track 25 times = 25 × distance in one loop of the track

    = 25 × 141.37

    = 3534.29 meters

what does is the c ? c + 13 = -17

Answers

Step-by-step explanation:

c + 13 = - 17

c = - 17 - 13

Therefore c = -30

Hope it will help :)

Answer:

c is equal to negative thirty.

Step-by-step explanation:

You can find out what c is by subtracting 13 from both sides of the equation:

c + 13 = -17

c + 13 - 13 = -17 - 13

c + 0 = -30

c = -30

You buy a total of 50 turkey burgers and veggie burgers for $90. You pay $2 per
turkey burger and $1.50
per veggie burger. WRITE and SOLVE a system of
linear equations to find the number y of veggie burgers that you buy.

Answers

Answer: There are 20 veggie burgers.

There are two ways you can solve this:

Let x represent turkey burger and y for veggie burger.

2x + 1.50y = 90
x + y = 50

Work:
-2(x + y = 50)
-2x + -2y = -100

2x + 1.50y = 90 << Add like terms
+ -2x + -2y = -100
______________
-0.50y = -10 << Solve for y
y = 20

____________________________

Let x represent turkey burger and y for veggie burger.

2x + 1.50y = 90
x + y = 50 << Solve for x

x = 50 - y << Plug in y for 2x + 1.50y = 90

2(50 - y) + 1.50y = 90
100 - 2y + 1.50y = 90
-0.50y = -10
y = 20




The number of 20 veggie burger, you bought.

What is the system of equations?

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

You buy a total of 50 turkey burgers and veggie burgers for $90.

You pay $2 per turkey burger and $1.50 per veggie burger.

Let x represents the turkey burger and y represents the veggie burger.

So, the system of equations,

x + y = 50   equation 1

2x + 1.5y = 90    equation 2

Substituting the value of x from the equation 1 to the equation 2,

100 - 2y + 1.5y = 90

y = 20

Then x = 30

Therefore, 20 veggie burgers you bought.

To find:

The coefficient of x in the given expression.

Solution:

Coefficient of a variable is the product of a number and other variables multiplying the variable in an algebraic expression.

In the given expression the number and variables other than x are -9, y² and z.

So, coefficient of x is

[tex]-9\times y^2\times z=-9y^2z[/tex]

Therefore, the correct option is (d).

Show that the two shorter sides in triangle A have the same length as the two shorter sides in triangle B

Answers

Answer:

Step-by-step explanation:

a). Let the unknown side of triangle A = x cm

And unknown side of triangle B = y cm

By applying Pythagoras theorem in triangle A,

13² = 12² + x²

x² = 169 - 144

x² = 25 ⇒ x = 5 cm

By applying Pythagoras theorem in triangle B,

y² = 5² + 12²

y² = 25 + 144

y = √169

y = 13 cm

Therefore, smaller sides of these triangles measure 5 cm and 12 cm and they are same in measure.

b). Since, corresponding sides of both the triangles are congruent,

By SSS property of congruence, both the triangles will be congruent.

A line with a negative slope intersects a horizontal line 3 units above the x-axis. Select each point that can not be the intersection of the two lines.

Answers

Step-by-step explanation:

Since both lines intersect each other 3 units above the x-axis, the y-value of the point of intersection must be 3.

Looking at the options, (-3, 5), (3, -2) and (0, -3) are all invalid points.

The points that can not be the intersection points are:

(-3, 5), (3, -2), and (0, -3)

Options B, C, and D are the correct answer.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

A line with a negative slope intersects a horizontal line 3 units above the x-axis.

This means,

The y-coordinate will be 3.

The y-intercept is y = 3.

The points of intersection will have the following form,

= (x, 3)

Thus,

(-3, 5), (3, -2), and (0, -3) can not be the intersection points.

Third Screenshot

A nonlinear function is a function that does not have a straight line graph. All linear functions are linear, except for Quadratic and up. Every polynomial function with the degree greater than one wont be a linear.

Fourth Screenshot

[tex]y = x + 3[/tex]

If we change the constant from 3 to 5 then we would get

[tex]y = x + 5[/tex]

The graph would shift up 2 units.

Last Screenshot

The second and third graph both are function. We can tell by doing a line test. Simply draw a vertical line first. Then we check if the line intercepts the graph more than a point or not.

If the line intercepts more than a point then it is not a function.

If the line intercepts only a point then it is a function.
