The slope of the line passing through the pairs of points (0, 7), and (0, −8) is not defined.

Here,

We have to find the slope of the line passing through the pairs of points (0, 7), and (0, −8).

What is slope of the line?

A measure of its steepness is called slope of line.

Now,

The points are (0, 7) and (0, -8)

Hence, Slope of the line is calculate as;

[tex]m = \frac{y_{2} -y_{1} }{x_{2}-x_{1} }[/tex]

[tex]m = \frac{-8 -7 }{0}-0 } = \frac{-15}{0}[/tex]

Which is undefined.

Hence, The slope of the line passing through the pairs of points (0, 7), and (0, −8) is not defined.

b= 81 degrees

Explanation:

A straight line is 180 degrees.

180 - 99 = 81

All the angles combined should be equal to 360, forming a circle.

In order to find angle b, we have to know what supplementary angles.

Supplementary angles are two angles that add up to 180°, or in other words, a straight line.

Angle b and the 99 degree angle are supplementary due to them creating a straight line when combined, so they add up to 180°.

To find angle b, subtract 99 degrees from 180.

180 - 99 = 81

Angle b is equal to 81 degrees.

When comparing these two sets of number, the first set is harder to find the different as you need to borrow from a column. For instance, when you start subtracting in the 10s place, you cannot take 40 away from 30.

Whereas in the second set, comparing the numbers is easy. They have the same 100s value and the same 10s value. You are simply comparing the 1s place.

Answer:

First, if we compare 645 and 738, the difference is significant, because those number have different units, different tenths and different hundreds.

However, if we compara 645 and 649, the difference isn't significant, because they have the same hundreds, the same tenths, but different units.

So, in terms of comparing numbers as such, we can tell that the difference in each comparison is about units, tenth and hundreds difference.

From this different comparison, the difference operation (subtraction) is also different, because it's not the same to subtract 645 from 738 than from 649, the difference is higher.

Final answer:

The length of the base of the square pyramid is calculated by rearranging the volume formula v = 1/3bh to solve for b, finding the base area, and then taking the square root to find the side length. With the given volume of 24 cm³ and height of 2 cm, the side length of the base is 6 cm. Therefore, the correct answer is C.

Explanation:

The student is asking how to find the length of the base of a square pyramid given its volume and height. The volume of a pyramid is given by the formula v = 1/3bh, where v is the volume, b is the area of the base, and h is the height. Since the pyramid is square, the area of the base (b) is equal to one side of the square base squared. With a volume (v) of 24 cm³ and a height (h) of 2 cm, we can substitute the values into the formula and solve for the base area b.

To find the side length of the base, we take the square root of the base area. Using the provided formula and values, we get:

v = 24 cm³

h = 2 cm

b = (3×v)/h = (3×24 cm³)/2 cm = 36 cm²

The side length of the base (l) is the square root of the base area: l = √b = √36 cm² = 6 cm. Therefore, the correct answer is C. 6 cm.

To find the balance at the beginning of the month, add the initial deposit and subtract the total transactions from the end of the month balance.

To find the balance at the beginning of the month, we need to subtract the total transactions from the end of the month balance. First, we need to find the total transactions by adding up all the transactions in Mr. Copley's checkbook. Then, we subtract the total transactions from the end of the month balance, $1473.61, and add the initial deposit of $75 that is not shown in his checkbook. This will give us the balance at the beginning of the month.

The balance at the beginning of the month is the result of the previous steps.

We can find the midpoint by using the two given coordinates and finding the average between them.

We will find the average between the x coordinates and the y coordinates.

We are given these two coordinates of line segment QR: (-3, 14) and (7, 5). Find the midpoint by finding the average (or mean) between the x coordinates (-3 and 7), and the y coordinates (14 and 5).

Find the average by adding up the two coordinates then dividing the answer you get by 2 (because you added two numbers).

x coordinates average: -3 + 7 = 4, 4/2 = 2; their average is 2

y coordinates average: 14 + 5 = 19, 19/2 = 9.5; their average is 9.5 (or 19/2)

Take the two averages and put them together so your answer is: the coordinate of the midpoint of line segment QR is (2, 19/2).

5(2x +8) = -8x + 4

Use distributive property:

10x +40 = -8x + 4

Subtract 40 from each side:

10x = -8x -36

Add 8x to each side:

18x = -36

Divide both sides by 18:

x = -36 / 18

x = -2

The number is -2

A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions. A heterogeneous mixture consists of visibly different substances or phases. The three phases or states of matter are gas, liquid, and solid.

Final answer:

A mixture is heterogeneous if it has a non-uniform composition, wherein the individual components can often be seen or separated. A mixture is homogeneous if it is uniform throughout, where the components are evenly distributed and cannot be visually distinguished. Examining the uniformity of the mixture's composition allows for differentiation between the two types.

Explanation:

To tell if a mixture is homogeneous or heterogeneous, one must first understand the definitions of these terms. A heterogeneous mixture has a composition that is not uniform throughout. Examples include trail mix, salad, and blood. These mixtures often allow the individual substances within them to be seen or separated by simple means, such as filtration or inspection.

In contrast, a homogeneous mixture is uniform in composition throughout the sample. Examples include air, simple syrup, and seawater. For instance, when salt is dissolved in water to create a saline solution, it is a homogeneous mixture because the salt is evenly distributed throughout the water and no longer visible as a separate substance.

Distinguishing between these two types of mixtures involves examining the uniformity of the mixture's composition. If different samples of the mixture have different compositions, or if the individual parts can be seen, it is heterogeneous. If it is uniform and the components cannot be visually separated, then it is homogeneous.

Answer:

A. 6 for apex

Step-by-step explanation:

The measure of ∠ A is 50°

A triangle is a polygon with three sides having three vertices. The angle formed inside the triangle is equal to 180 degrees.

Given that a triangle ABC, and angle B and C are 100° and 30° respectively,

According to angles sum property of a triangle, we have,

∠ A + ∠ B + ∠ C = 180°

∠ A = 180° - (100° + 30°)

∠ A = 180° - 130°

∠ A = 50°

Hence, the value of angle A is 50°
