The value of z is found by dividing y by x, which results in  z =\(-\frac{16}{63}$\)

To solve for z, we can use the equation \($x\cdot z = y$\). We know that \($x = \frac{7}{8}$\) and \($y = -\frac{2}{9}$\),

Therefore, we can enter these values into the equation as substitutes:

\($\frac{7}{8} \cdot z = -\frac{2}{9}$\)

Next, In order to separate z, we must divide both sides of the equation by \($\frac{7}{8}$\):

\($z = \frac{-\frac{2}{9}}{\frac{7}{8}}$\)

To divide by\($\frac{7}{8}$\), The fraction can be rotated, then multiplied by its reciprocal, which is \($\frac{8}{7}$\)

\($z = \frac{-\frac{2}{9}}{\frac{7}{8}} \cdot \frac{8}{7}$\)

The fraction on the right can be made simpler as follows:

\($z = -\frac{2}{9} \cdot \frac{8}{7} = -\frac{16}{63}$\)

So, The value of z is found by dividing y by x, which results in  z =\(-\frac{16}{63}$\)

Answer:

the second answer is right

Step-by-step explanation:

while it is true that W=25/8, the definition itself (25/8) makes it a rational number (= a ratio of 2 integer numbers). so, in total, the first answer is therefore wrong.

X=pi, and pi is a typical example of an irrational number. so, this second answer is correct.

sqrt(10) < 3.16666666666...

so, Y=sqrt(10) and not 3.166666666..., so the third answer is already wrong there.

and consequently, Z=3.166666... and not sqrt(10), so the fourth answer is therefore also wrong.

If the scale factor is 3/4. Then the perimeter of the original triangle will be 66.67 units.

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.

A triangle with a perimeter of 50 units is the image of a triangle that was dilated by a scale factor of 3/4.

Then the perimeter of the preimage, the original triangle, before its

The dimensions of a horizontal cross-section will vary depending on the specific shape or object being considered.

To determine the dimensions of a horizontal cross-section, we need more specific information about the object or shape in question.

A horizontal cross-section refers to a slice or cut made parallel to the horizontal plane.

The dimensions of a horizontal cross-section will depend on the shape or object being sliced. For example, if we have a rectangular prism, a horizontal cross-section would result in a rectangle.

The dimensions of this rectangle would be equal to the dimensions of the corresponding face of the prism.

If we have a cylindrical object, a horizontal cross-section would result in a circle. The dimensions of this circle would be determined by the radius or diameter of the cylinder.

It is essential to provide more information about the shape or object to determine its corresponding horizontal cross-section dimensions.

To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.

The constant of proportionality for the relationship of millimeters of rainwater to time in hours is 48 millimeter/hour.

Given that the measuring tool captures rain falling at a constant.The table shows the height of rainwater in the measuring tool and the number of minutes it rains as shown in attached image.

A ratio is a mathematical comparison between two numbers. In proportion, if two given sets of numbers increase or decrease by the same ratio then the given ratios are said to be proportional.

Now we will calculate the proportion by using the formula

Ratio=(r₂-r₁)/(t₂-t₁)

Here, r₁=4, r₂=8, t₁=5, t₂=10

So, r₂-r₁=8-4=4 and

t₂-t₁=10-5=5

Now, we will convert the time from min to hour by dividing it with 60, we get

t₂-t₁=5/60

Substitute this value in above equation, we get

Ratio=4/(5/60)

Ratio=(4×60)/5

Ratio=4×12

Ratio=48 mm/hr

Hence, the constant of proportionality for the relationship of millimeters of rainwater to time in hours by using the given table is 48 mm/hr.

Answer:

Step-by-step explanation:

When the coloured water evaporates and condenses on the inside of the top cup, there is no colour in the water on the inside surface of the cup.

As water molecules in the air cool, they slow down and combine into tiny droplets of liquid water. This process is called condensation. This happens when water molecules in the air touch the outside of a cold mug exposed to air.

Water vapour in the air is extracted by several techniques, such as cooling the air below the dew point, exposing the air to a desiccant, using membranes that allow only water vapour to pass, collecting the mist, or pressurizing the air. I can do it.

Common examples are water forming on the outside of a cold mug, or moisture forming on a car window on a cool night.

Answer:

y=2/3x-7

Step-by-step explanation:

The slope intercept formula is

y=mx+b

(m) is the slope (rate of change)

(b) is the y intercept (where the line crosses the y axis [vertical])

We need to find the slope and the y intercept. First we will find the slope.

The formula for slope is y1-y2/x1-x2

In and ordered pair the first value is the (x) and the second is the (y).

(x, y)

We take the (y) of one of the given points and subtract the (y) of the second given point, then divide it by the (x) of one of the given points and the (x) of the other given point.

5-(-1)/8-4

Simplify.

5-(-1) =5+1= 6

8-4=4

6/4 Simplify

3/2 is our slope.

Now we apply out new slope into our y=mx+b

y=3/2x+b

Now we need to find the (b) which is the y intercept.

To do this we need to use one of our given points, you can choose either but for this I'll use (4, -1).

In this ordered pair 4 is the (x) and -1 is the (y)

So replace (y) with -1 and (x) with 4

-1=3/2(4)+b

Now solve as usual.

-1=6+b

subtract 6 from each side

-7=b

b=-7

Put our (m) and (b) into our formula.

y=2/3x-7 is our equation.

Answer:

Step-by-step explanation:

Let y represent the amount of money earned, and x the number of cars they wash. Then

y = 5x

Why? Each car wash costs $5. So no car washes means no earnings; 1 car wash earns $5; 2 washes earn $10; 3 washes earn $15, and so on, so that x car washes generate $5x.

2. No matter how many cars they end up washing, they will have spent $75 to set up the operation, so you subtract 75 from the equation is part (1).

3. Taking into account the setup cost of $75, the profit they make is given by

y = 5x - 75

Answer:

x = 35

Step-by-step explanation:

The sum of the exterior angles of a polygon = 360°

Then

1 exterior angle = 360° ÷ 8 = 45° , so

x + 10 = 45 ( subtract 10 from both sides )

x = 35

The value of x for the octagon considering the value of the exterior angle is; x = 35°

The sum of the exterior angles of a regular polygon is 360°

Now, we are told that the measure of an exterior angle of a regular polygon is (x + 10)°. Thus;

For an octagon, we have;

8(x + 10)° = 360°

8x + 80 = 360

8x = 360 - 80

8x = 280

x = 280/8

x = 35°

Thus, the value of x for the interior angle is 35°.

The green triangle represents the image triangle.

Step-by-step explanation:

We know that when we reflect a point across the y-axis, the y-coordinate remains the same but the x-coordinate reveres its sign.

Thus,

The rule of reflection of the point P(x, y) across the y-axis is:

P(x, y) → P'(-x, y)

In the attached figure, let the coordinates of the triangle are:

Using the rule of reflection across the y-axis:

P(x, y) → P'(-x, y)
