Answer: each base angle in an isosceles right triangle measures 45 degrees.

Step-by-step explanation:

In an isosceles right triangle, two sides have equal lengths, and one angle is a right angle (90 degrees).

Since it is an isosceles triangle, the two base angles (the angles opposite the equal sides) must be congruent, meaning they have the same measure.

To find the measure of each base angle, we can use the fact that the sum of the angles in a triangle is 180 degrees.

Let's denote the measure of each base angle as "x". Then, the sum of the three angles in the triangle can be expressed as:

x + x + 90 = 180

Simplifying the equation:

2x + 90 = 180

Subtracting 90 from both sides:

2x = 90

Dividing both sides by 2:

x = 45

The distance of Satellite B from the Earth is approximately 4915.71 kilometers.

To determine the distance of Satellite B from the Earth, we can use the concept of similar triangles.

Let's break down the problem step by step:

We have a triangle formed by Satellite A, Satellite B, and the center of the Earth.

Let's call the center of the Earth point O, Satellite A point A, and Satellite B point B.

Since Satellite A orbits closer to the Earth, its distance from the center of the Earth is equal to the radius of the Earth plus the distance from Satellite A to Satellite B.

Let's call this distance OA.

OA = Radius of the Earth + Distance from Satellite A to Satellite B

OA = 6371 km + 21185.5 km

OA = 27556.5 km

Now, we need to find the distance of Satellite B from the Earth. Let's call this distance OB.

We know that OA and OB form a triangle, and they are parallel to the side AB.

Since the triangle formed by OA, OB, and AB is similar to the triangle formed by OA, AB, and the radius of the Earth, we can set up a proportion to find OB.

OA / AB = Radius of the Earth / OB

OB = (Radius of the Earth x AB) / OA

OB = (6371 km x 21185.5 km) / 27556.5 km

OB ≈ 4915.71 km

Therefore, the distance of Satellite B from the Earth is approximately 4915.71 kilometers.

The reason that is NOT typically used in a proof is two angles being congruent. Option C.

Among the options A, B, C, and D, the reason that is NOT typically used in a proof is option C: two angles being congruent.

Congruence is a fundamental concept in geometry that refers to the equality of shape and size. When two angles are congruent, it means they have the same measure. While congruence is an important concept used in geometric proofs, it is typically not used as a standalone reason in a proof.

In geometric proofs, various properties, theorems, and postulates are used to establish relationships and make deductions. Let's briefly discuss the other options:

A. Definition of supplementary angles: This is a valid reason that is commonly used in proofs involving supplementary angles. The definition states that if the sum of two angles is 180 degrees, they are considered supplementary.

B. Substitution property: The substitution property is a logical property used in algebraic proofs. It allows us to replace one expression with another expression that is equal to it. This property is often employed when simplifying equations or substituting known values.

D. Parallel lines: The concept of parallel lines is frequently utilized in geometric proofs, particularly in proving angles and angle relationships. Properties such as alternate interior angles, corresponding angles, and vertical angles are established based on the parallel lines. Option C is correct.

Step-by-step explanation:

The cumulative frequency to be used in solving the 28th percentile is 16.

Cumulative frequency is described as  the total of a frequency and all frequencies in a frequency distribution until a certain defined class interval.

we add up the frequencies until we reach or exceed 28% of the total data set in order to find the cumulative frequency for the 28th percentile.

Total frequency = 4 + 9 + 16 + 10 + 9 + 2 = 50

28th percentile = (28/100) * Total frequency

28th percentile = (28/100) * 50 = 14

We start from the beginning of the distribution and add up the frequencies until we reach or exceed 14 so as to find the cumulative frequency.

In conclusion, and with reference to the given data set we notice that the cumulative frequency exceeds 14 at the 91-120 minute interval = 16.

Step-by-step explanation:

The equation representing the given sentence would be:

42 = 23 + j

Here, the variable "j" represents Janelle's age.

The scale factor of the dilation is 4.

We are given that;

The equation of line −11x=4y+4

Now,

The center of dilation is the origin (0, 0). The line given by −11x = 4y + 4 can be rewritten as y = −11/4 x − 1. This means that it passes through the points (0, −1) and (−4, 0). The image of the line after dilation is given by −11x − 4y = 16, which can be rewritten as y = −11/4 x − 4. This means that it passes through the points (0, −4) and (−16, 0).

To find the scale factor, we can use any pair of corresponding points. For example, let’s use (0, −1) and (0, −4). The distance from the center of dilation to (0, −1) is 1 unit. The distance from the center of dilation to (0, −4) is 4 units. Therefore, the scale factor is 4/1 = 4.

The total volume of the 21 bowling balls is 6048π cubic inches.

We have,

To find the total volume of the 21 bowling balls, we first need to calculate the volume of a single ball and then multiply it by the number of balls.

The volume of a sphere can be calculated using the formula:

V = (4/3) x π x r³

where V is the volume and r is the radius of the sphere.

Given that the diameter of the bowling ball is 12 inches, the radius can be calculated as half of the diameter:

r = 12/2 = 6 inches

Now we can calculate the volume of a single ball:

V_ball = (4/3) x π x (6³) = (4/3) x π x 216 = 288π cubic inches

Since there are 21 balls, we can calculate the total volume by multiplying the volume of a single ball by the number of balls:

Total volume = 21 x 288π = 6048π cubic inches

The restriction of a function f is when the domain of f is limited to a subset of its original domain.

The restriction of a function f can be demonstrated by considering a function f: R -> R, where R represents the set of real numbers.

Let u say f(x) = x^2. Now, if we restrict the domain of f to the interval [0, 5], the new function becomes f restricted: [0, 5] -> R and its expression would be f restricted(x) = x^2 for x in the interval [0, 5].

This means that the function f restricted only takes inputs from the interval [0, 5] and behaves the same way as the original function within that interval.

Step-by-step explanation:

The numbers -7, -5, -3, 3, -1, and 1 can be arranged into three pairs with the same total (-7, 7), (-5, 5), (-3, 3), (-1, 1).

To arrange the numbers -7, -5, -3, 3, -1, and 1 into three pairs with the same total, we need to find a combination of pairs that will give us the same sum for each pair.

Let's start by examining the numbers:

-7, -5, -3, 3, -1, 1

To find pairs with the same total, we can start by pairing the numbers with their additive inverses (numbers that sum to zero). In this case, -7 and 7, -5 and 5, -3 and 3 can be paired up. This leaves us with -1 and 1.

We have three pairs now: (-7, 7), (-5, 5), (-3, 3). However, we still have -1 and 1 remaining. To make the sum of the pairs equal, we can pair -1 with 7 and 1 with -5.

The three pairs with the same total are:

(-7, 7), (-5, 5), (-3, 3), (-1, 1).

Each pair sums up to zero, resulting in the same total for each pair. For example, (-7 + 7 = 0), (-5 + 5 = 0), and so on.

Therefore, the numbers -7, -5, -3, 3, -1, and 1 can be arranged into three pairs with the same total:

(-7, 7), (-5, 5), (-3, 3), (-1, 1).

It will take John approximately 2.69 hours to paint the room alone.

Let's denote the individual rates of John, Rick, and Molli as J, R, and M, respectively. We are given the following information:

John, Rick, and Molli can paint the room together in 5 hours.

Molli alone can paint the room in 14 hours.

Rick alone can paint the room in 10 hours.

To find the equation comparing the group rate to the sum of the individual rates, we can use the concept of work done. The amount of work required to paint the room is the same, regardless of who is doing the work.

The equation can be expressed as:

1/5 = 1/J + 1/R + 1/M

Now, let's substitute the given information into the equation. We know that:

M = 14 (since Molli can paint the room alone in 14 hours)

R = 10 (since Rick can paint the room alone in 10 hours)

Substituting these values, the equation becomes:

1/5 = 1/J + 1/10 + 1/14

To solve for J, we can find the least common denominator (LCD) of 10 and 14, which is 70:

14J + 7J + 5J = 70

26J = 70

J = 70/26

J ≈ 2.69

For an item with a marked price of Rs. 26,600 and a 10% discount, the discount price is Rs. 2,660. Therefore, the customer will pay Rs. 23,940 after applying the discount.

To calculate the amount of discount on an item with a marked price of Rs. 26,600 and a discount percentage of 10%, we can follow a simple formula.

First, let's calculate the discount amount. The discount percentage is 10%, which means we can find the discount amount by multiplying the marked price by the discount percentage:

Discount amount = Marked price × Discount percentage

= Rs. 26,600 × 10/100

= Rs. 2,660

So, the discount amount for the item is Rs. 2,660.

Now, let's understand what this means. A discount is a reduction in the original price of an item. In this case, the discount amount of Rs. 2,660 is the amount by which the price of the item is reduced. Therefore, after applying the discount, the customer would only need to pay Rs. 26,600 - Rs. 2,660 = Rs. 23,940.

It's important to note that the discount amount is not the final price the customer pays. The final price is the marked price minus the discount amount. So, in this scenario, the customer will receive a discount of Rs. 2,660, and they will pay Rs. 23,940 for the item.

Understanding how discounts work can be helpful when making purchasing decisions or comparing prices. It allows customers to evaluate the value they are receiving and make informed choices based on their budget and preferences.

Given statement solution is :- The area (A) of the base of the cylinder, you need to use the formula for the area of a circle, which is A = [tex]πr^2[/tex], where π is approximately 3.14 and r is the radius of the base.

To calculate the area (A) of the base of the cylinder, you need to use the formula for the area of a circle, which is A = [tex]πr^2[/tex], where π is approximately 3.14 and r is the radius of the base.

Given that the radius (r) is 10 cm, the area of the base (ABase) can be calculated as follows:

ABase =[tex]πr^2[/tex]

ABase = 3.14 * [tex](10 cm)^2[/tex]

ABase = 3.14 * [tex]100 cm^2[/tex]

ABase = 314 [tex]cm^2[/tex]

The area of the base is [tex]314 cm^2.[/tex]

To calculate the volume (V) of the cylinder, you need to multiply the area of the base (ABase) by the height (h):

We have to calculate how many weeks it will take both crews to complete the tunnel.

585 feet have already been dug from the south end. So, the total tunnel length that needs to be dug is 7605 - 585 = 7020.

Now, let's assume that both the crews continue to work at their respective rate of A = 58 ft/week and B = 59 ft/week.

Therefore, total tunnel length that needs to be dug in weeks = (7020 ft) / (A + B)
