The time needed to travel the entire distance is given as follows:

1.27 minutes.

Before obtaining the time, we need to obtain the entire distance.

The distance is the perimeter of the rectangle, which is the sum of all the outer side lengths of the right triangle.

The sides of the right triangle are given as follows:

40 yards and 70 yards.

Applying the Pythagorean Theorem, the length of the hypotenuse is given as follows:

h² = 40² + 70²

[tex]\sqrt{40^2 + 70^2}[/tex]

h = 80.6 yards.

Then the total distance is given as follows:

40 + 70 + 80.6 = 190.6 yards.

The time is given by the division of the distance by the velocity of 150 yards per minute, hence:

t = 190.6/150

t = 1.27 minutes.

Step-by-step explanation:

The number of students surveyed: 53 + 46 = 99 students
The number of student having both: 99 - 87 = 12 students

Answer:

Let's call the total amount of the lottery winnings x.

If Kelly took one half of the earnings, then she took 1/2x and Toey took 1/2x as well.

Toey spent 1/4 of his earnings, so he spent 1/4*(1/2x) = 1/8x

So Joey spent 1/8 of the total lottery winnings.

To graph the system of equations 3x - 2y = 4 and 3x + 2y = 8, we first need to solve for the value of x and y.

To solve for x and y, we can use the first equation 3x - 2y = 4,

3x - 2y = 4

y = (3x/2) - 2

we can substitute this value of y into the second equation 3x + 2y = 8

3x + 2(3x/2 - 2) = 8

3x + 3x - 4 = 8

6x = 12

x = 2

Now we can substitute the value of x into the first equation to find the value of y

3(2) - 2y = 4

6 - 2y = 4

-2y = -2

y = 1

so the point of intersection is (2,1)

In order to graph the system of equations, we can plot the point of intersection (2,1) and then use the slope-intercept form of the equations to graph the lines.

The slope-intercept form of the first equation is y = (3/2)x - 2

The slope-intercept form of the second equation is y = (1/2)x + 4

So, the lines have a slope of 3/2 and 1/2 respectively.

We can now plot these lines on the coordinate plane, with the point of intersection (2,1) being the point where the lines cross.

The graph of the system of equations is the two lines crossing at the point (2,1)

The x-intercept of the equation y=-13x+234 is (18,0).

The point slope form is used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point.

The equation of the point slope form is: (y - y₁) = m(x - x₁)

where, (x, y) is a random point on the line and m is the slope of the line.

1) From the give table, we have (18, 0) and (15, 39).

Here, slope(m) = (39-0)/(15-18)

m= -13

2) Substitute m= -13 and (x₁, y₁)=(18, 0) in point slope form, we get

(y-0)= -13(x-18)

y=-13x+234

To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.

x-intercept(s): (18,0)

y-intercept(s): (0,234)

Therefore, the x-intercept of the equation y=-13x+234 is (18,0).

A worker's starting wage at this job is $13.5.

$31.70 per hour can be expected after 7 years of experience.

What is the system of equations?

System of equations, also known as simultaneous equations, Two or more equations to be solved together in algebra (i.e., the solution must satisfy all the equations in the system). The number of equations must equal the number of unknowns for a system to have a unique solution.

Given that a worker earns $16.10 per hour with 1 year of experience.

The other worker earns $21.30 per hour with 3 years of experience.

The model that represents the wages of a worker is

y = ax + b

Where x is the number of years of experience, and y is total wages.

Now putting x =1 and y = 16.10 in y = ax + b:

16.10 = a + b .....(i)

Now putting x =3 and y = 21.30 in y = ax + b:

21.30 = 3a + b .....(ii)

Subtract equation (ii) from equation (i)

3a + b =21.30

a + b = 16.10

(-)  (-)    (-)

__________

2a = 5.2

a = 2.6

Putting a = 2.6 in equation (i)

16.10 = 2.6 + b

b = 16.10 - 2.60

b = 13.5

The model is y = 2.6x + 13.5

A worker's starting wage is $13.5 at this job.

Putting x = 7  in y = 2.6x + 13.5:

y = 2.6×7 + 13.5

Answer:

z = -8/3 - 5i

Step-by-step explanation:

Sorry, I don't know what a ti-84 calculator is.

But, I can solve this question normally.

Let the real part of z be x and the imaginary part be y.

z = x + iy

|z| = √(x²+y²)

z + |z| = x + iy + √(x²+y²) = 3 - 5i

Now, y has to be -5 as |z| is a real number so the only component affecting i is y. Therefore, y = -5.

Now, lets figure out the real part.

Cancel out imaginary part.

x + √(x² + 25) = 3

3 - x = √(x² + 25)

squaring on both sides,

9 + x² - 6x = x² + 25

6x = -16

x = -8/3

Hence the required complex number is -8/3 - 5i

When the number of blue frogs increased by 60% and the number of green frogs decreased by 60%, the percentage of the overall increase is solved to be 60%

Assuming the number of blue frogs and the number of green frogs are equal and = y

Increasing the percentage of each by 60%, the factor for percentage increase by 60% is 1.6

hence 1.6y + 1.6y = 3.2y

percentage change

= change in price / original price * 100

Using circle theorems, the value of x in the cyclic quadrilateral is 6 units

A cyclic quadrilateral is a four-sided shape whose vertices all lie on the same circle. This means that all four angles of the quadrilateral are equal to one another.

This is further explained by circle theorem which is a branch of mathematics that deals with the properties of circles and their relationships with other shapes. It is based on the fact that all points on a circle are equidistant from the center of the circle. Circle theorem has many applications, such as finding the area of a circle, calculating the circumference of a circle, and even determining the angles of a triangle formed by three points on a circle.

In this given problem, to find the value of x, we have to use proportions or ratios of the sides given.

The shape of the ABCD is a rhombus. The diagonals are not equal to each other.

What is the 2-dimensional shape?

A two-dimensional shape with horizontal and vertical axes is known as a 2d shape (x-axis and y-axis). Two-dimensional shapes have only length and width. There is no thickness or height to these shapes.

Given the vertices of ABCD are  A(-3,0), B (1,5), C(-3,10) and D(-7,5).

The formula distance between points (x₁, y₁) and (x₂, y₂) is √[(x₂ - x₁)² + (y₂ - y₁)²].

The distance between A and B is √[(1 - (-3))²+(5 - 0)²] = √(4²+5²) = 6.4

The distance between B and C is √[(-3 - 1)²+(10 - 5)²] = √(4²+5²) = 6.4

The distance between C and D is √[(-7 - (-3))²+(5 - 10)²] = √(4²+5²) = 6.4

The distance between A and D is √[(-7 - (-3))²+(5 - 0)²] = √(4²+5²) = 6.4

The distance between A and C is √[(-3 - (-3))²+(10 - 0)²] = √(10²) = 10

The distance between B and D is √[(-7 - 1)²+(5 - 5)²] = √(8²) = 8

The slope of a line passes through the points (x₁, y₁) and (x₂, y₂) is (y₂ - y₁)/(x₂ - x₁).

The slope of AB is (5-0)/(1-(-3))=5/4

The slope of BC is (10-5)/(-3-1)=-5/4

The slope of CD is (5-10)/(-7-(-3))=5/4

The slope of AD is (5-0)/(-7-(-3))=-5/4

The number of vertices of the quadrilateral is 4.

Thus it is either a square or rectangle or rhombus or parallelogram.

Since the length of all sides is equal thus it is either a square or rhombus.

Since the diagonals are not equal it is a rhombus.
