Answer:

7.5

Step-by-step explanation:

W -- X -- Y ----- Z

We are given that :

Given this we want to find XZ

XZ consists of XY and YZ so we must find the length of the individual segments.

Finding YZ

Here, we know that YZ = WY as y is the midpoint of WZ. If WY = 5 then YZ also = 5

Finding XY

Given that WY = 5 and that X is a midpoint of WY we know that the segments WX and XY = WY and are congruent.
In other words we can say that 2XY = WY

==> WY = 5

2XY = 5

==> divide both sides by 2

XY = 2.5

Finding XZ

Again, XY + YZ = XZ

We have XY = 2.5 and YZ = 5

Hence, 2.5 + 5 = XZ

XZ = 7.5

Answer:

XZ = 7.5

Step-by-step explanation:

A drawing is sometimes very helpful.

Start by drawing a segment with endpoints W and Z.

   +--------------------------------------------+

   W                                                  Z

Y is the midpoint of WZ. Draw point Y in between W and Z and the same distance from both W and Z.

    +---------------------+--------------------+

   W                        Y                       Z

X is the midpoint of WY. Draw X between W and Y, and the same distance to W and Y.

   +----------+----------+--------------------+

   W          X           Y                       Z

Because of the midpoints, we know that:

WX = XY

WY = YZ

WY = 5

WX and XY are each half of WY, so WX = XY = 5/2 = 2.5

WY = YZ = 5

XZ = XY + YZ

XZ = 2.5 + 5

XZ = 7.5

Maya drove on the mountains for her trip. Due to traffic, her average rate of miles per hour was faster at the time of coming back to her home than going on her trip. Thus, The distance between where she lives and the mountains is

288 miles .

Let's consider that Maya live x miles from the mountains.

Let her rate to mountains be y miles/h.

we have given that

Driveing time taken by Maya going from home to trip location= 9 hours due to traffic

total return time taken by her = 4 hours

average rate = 40 miles/hour

Using rate formula,

Rate = distance/time

=> distance (d) = rate (r) × time (t)

so, x/y = 9

=> x=9y --(1)

Return trip 4 hours then rate = y+40

=> x/(y+40) =4 --(2)

using Substitution method, x= 3 substitute in (2)

=> 9y/(y+40)=4

=> 9y=4y+160

=> 9y-4y=160

=> 5y=160

=> y= 160/5

=> y=32

Now, x=9y

x=9×32= 288 miles

Hence, distance to the mountain is 288 miles.

The solution of the system of equations:

y = x + 422

y + 4  =x

is the point (-88, -46)

Here we have the system of equations:

y = x + 42

2y + 4  =x

To solve the system, we can replace the first equation into the second one:

2*(x + 42) + 4 = x

2x + 84 + 4 = x

2x + 88 = x

2x - x = -88

x = -88

And the value of y is:

y = x + 42

y = -88 + 42 = -46

The solution is the point (-88, -46).

The linear equation written in the slope-intercept form is:

y = -x - 5

A linear equation can be written in the slope-intercept form as:

y = m*x + b

Where m is the slope and b is the y-intercept.

Particularly, if the line passes through the points (x₁, y₁) and (x₂, y₂) then the slope of the line is written as:

m = (y₂ - y₁)/(x₂ - x₁)

Here we can use the first two points on the table (or any you want) to find the slope:

(-1, -4) and (3, -8)

m = (-8 + 4)/(3 + 1) = -1

The slope is -1, so the line is something like:

y = -x + b

To find the value of b we can use another of the points on the table, if we use (7, -12) then we must have:

-12 = -7 + b

-12 + 7 = b

-5 = b

On solving the given  question, we got that -  the polynomial function of lowest degree with rational real coefficients is [tex]= > P(x) = 3x^{2} - 21x + 30[/tex]

Polynomial equations are those created using variables, exponents, and coefficients. The higher exponent, known as the equation's degree, can have a variety of exponents. By factoring polynomials based on the degree and variables in the equation, we can solve them.

We are aware that the lowest degree polynomial function, denoted by p(x), has the following properties:

[tex]= > P(x) = c(x - a)(x - b)\\[/tex]

The leading coefficient is 3, the roots are 5, and the roots are 2, respectively.

Therefore, the lowest degree polynomial with the aforementioned characteristics is:

[tex]= > P(x) = 3(x - 5)(x - 2))\\= > P(x) = 3(x^{2} - 7x + 10)\\= > P(x) = 3x^{2} - 21x + 30\\[/tex]

x^2 + y^2 = z^2 is the pythagorean theorem.

If you divide the large triangle into two separate ones, with sides 7, 4 and 0.5y, you can use the pythagorean theorem to figure out 0.5y. So:

7^2 = 4^2 +(0.5y)^2

Answer: He spent 3 hours as a cashier and 6 hours as a lifeguard

Step-by-step explanation:

First, you figure out his time as a cashier; 12($ per hour) x 3(hours working) = $36. Then, since it states he spent twice as many hours being a lifeguard, you double his hours when figuring out his time as a lifeguard; 18($ per hour) x 6(hours working) = $108. Add up both of your totals, $108 + $36 = $144.

Answer:

Step-by-step explanation:

The line segments joining the given points are not parallel.

In order to find the slope of a line, calculate the angle it makes with x axis as a reference. Then its slope can be determined by taking tan ratio of that angle.

Given that,

The first segment is joined from (3, -3) to (3, 9).

And, the second segment is joined from (-5, 12) to (1, 0).

In order for the segments to be parallel, their slope must be equal.

The slopes of both the segments can be found as,

First segment,

Slope = (3 - 3)/(-3 - 9)

          = 0/-12

          = 0

Second segment,

Slope = (-5 - 1)/(12 - 0)

          = -6/12

          = -1/2

Since slopes of the segments are not equal, they are not parallel.

Hence, the given line segments are not parallel.

The percentage of his tip compared to the cost of the iced coffee drink is 17.57%.

Percentage is defined as part of a whole expressed in hundredths or out of 100. It is usually written with the symbol "%".

To determine the percentage, we must first determine the proportion of the amount of the tip compared to the cost of the drink he purchased by dividing the two values. After that, multiply the answer by 100.

percentage = (amount of the tip/cost of the iced coffee drink) x 100

percentage = ($1/$5.69) x 100

percentage = 0.175747 x 100

percentage = 17.57%

Answer:

The ratio of mangos to grapes is 2:7.

Step-by-step explanation:

The original ratio of mangos to grapes would be 4:14. When it says mangos to grapes, it means mangos first, then grapes. If it said grapes to mangos, the grapes would go first. But, in this case the mangos go first. Now, we don't worry about the strawberries because it says to find the ratio of mangos to grapes, which is 4:14. Now, it says to simplify it to the simplest form. So, we can do this by dividing both numbers by the same number down as far as they can go as a whole number (a number without a decimal):

4 ÷ 2 = 2

14 ÷ 2 = 7

So, this is as far as we can go. So, our final answer is 2:7.
