The right triangle BCD have the following solution:

a). The opposite side to the angle D is BC and the adjacent side is DC

b). sin D = 0.55

c). D = 33°

d). B = 57°

Considering the angle D for right triangle BCD, the side opposite the angle D is BD which is also equal to 11 cm, and the side adjacent to the angle D is DC.

sin D = 11/20 {opposite/hypotenuse}

sin D = 0.55 to the nearest tenth

D = sin⁻¹(0.55)

D = 33.3670

D = 33 to the nearest degree

angle B = 180 - (90 + 33) {sum of interior angles of a triangle}

angle B = 57°.

Therefore, the right triangle BCD have the following solution:

a). The opposite side to the angle D is BC and the adjacent side is DC

b). sin D = 0.55

7 liters = 7000 milliliters

Answer:

It depends on the context of the problem and the interpretation of the ratio represented by the point (7, 8).

If we interpret the point (7, 8) as representing the ratio 7:8, then Adela's claim is incorrect. Adding the same number to both coordinates of the point would change the value of the ratio. For example, adding 1 to both coordinates would give the point (8, 9), which represents the ratio 8:9, which is not equivalent to 7:8.

However, if we interpret the point (7, 8) as representing a different type of ratio, such as the ratio of the distances from the point to two fixed points or the ratio of the areas of two shapes, then it may be possible to find an equivalent ratio by adding the same number to both coordinates of the point. In this case, Adela's claim could be correct.

Without more information about the context and interpretation of the ratio represented by the point (7, 8), it is difficult to determine the correctness of Adela's claim.

The area of the sector formed by angle DFE is approximately 3.29 square feet.

What is area of the sector?

To find the area of a sector of a circle, we need to know the central angle that defines the sector and the radius of the circle. We can then use the formula:

Area of sector = (central angle / 360 degrees) x π x (radius)²

In this case, we are given that the radius of the circle is 4 feet and the central angle that defines the sector is 75 degrees. Therefore, the area of the sector can be calculated as:

Area of sector = (75 / 360) x π x (4)²

= (0.2083) x π x 16

= 3.29 square feet (rounded to the nearest hundredth)

Therefore, the area of the sector formed by angle DFE is approximately 3.29 square feet.

If triangle ABC has points A(2, -4) B(-3, 1) C(-2, -6) and you perform the following transformations, B' would be located at B' (3, -4).

In Mathematics, a translation is a type of rigid transformation which is used in moving every point of an object in the same direction, as well as for the same distance.

By applying a reflection over the y-axis to the coordinate of the given point B (-3, 1), we have the following coordinates:

Coordinate B = (-3, 1)   →  Coordinate B' = (-(-3), 1) = (3, 1).

Next, we would apply a rotation of 90° clockwise as follows;

(x, y)                               →            (y, -x)

Coordinate B' = (3, 1) → Coordinate B' = (1, (-3)) = (1, -3)

Lastly, we would apply a translation (x + 2, y - 1) as follows:

Coordinate B' = (1, -3) → (1 + 2, -3 - 1) = B' (3, -4).

Answer:

Step-by-step explanation:

Let the amount invested by A, B, and C be denoted by a, b, and c respectively.

From the given information,

a + b + c = 60000 ---(1)

a + c = 2b ---(2)

a + b = 3c ---(3)

Multiplying equation (2) by 3 and equation (3) by 2, we get:

3a + 3c = 6b

2a + 2b = 6c

Adding these two equations, we get:

5a + 5b + 5c = 0

a + b + c = 0

This is not possible as the sum of the investments cannot be zero. Therefore, there must be an error in the problem statement.

Without further information or correction, it is not possible to find the share of B in the profit.

Comparing the numerator 9 < 15 thus, 9/10 is less than 3/2.

A multiple of the denominators of two or more fractions can be used as a common denominator to add, subtract, or compare the fractions. As fractions with dissimilar denominators cannot be added together or directly compared, they must be changed into comparable fractions with the same denominator. We must determine the least common multiple (LCM) of the fraction denominators in order to determine a common denominator. The lowest number that is a multiple of both denominators is known as the LCM. Once we have the common denominator, we may multiply the numerator and denominator by the same factor to change each fraction to an equal fraction with the same denominator.

The two values are 9/10 and 3/2.

Taking the LCM we have:

9/ 10 and 15/10

b.To sketch the budget line, we can plot the points (0, I/8), (I/4, 0), and (5I/16, 3I/16) on a graph.

c.The lowest price of books that Lizzy will substitute for Milo is $6.

A budget line is a graphical representation of all possible combinations of two goods that can be purchased with a limited amount of income or resources. It shows the various combinations of two goods that a consumer can afford to buy with a given income and the prices of the two goods.

In the given question,

a. The equation of Lizzy's budget line can be written as:

4M + 8B + 20(20)S + 20(40)J = I

where M is the number of tins of Milo, B is the number of books, S is the number of pairs of shoes, J is the number of pairs of jeans, and I is the total income or budget.

Interpretation: This equation represents all the possible combinations of Milo, books, shoes, and jeans that Lizzy can buy with her given income. It shows that she has to choose between buying more of one good and less of the other goods depending on their prices and her budget.

b. To sketch the budget line, we need to solve the equation for one of the variables. Let's solve for B:

4M + 8B = I - 20(20)S - 20(40)J

B = (1/2)I - 40S - 40J - 2M

What is budget line?

A budget line is a graphical representation of the limits of a consumer's purchasing power, given their income and the prices of goods and services. It shows all the possible combinations of two goods that a consumer can purchase with a given income, while spending all of their available resources.

a. The equation of Lizzy's budget line can be written as:

4M + 8B + 20(20)S + 20(40)J = I

where M is the number of tins of Milo, B is the number of books, S is the number of pairs of shoes, J is the number of pairs of jeans, and I is the total income or budget.

This equation shows that the maximum number of books that Lizzy can buy depends on her income (I), the prices of shoes (S) and jeans (J), and the number of tins of Milo (M) she buys. The slope of the budget line is -4, which means that for every 1 unit increase in the number of books, Lizzy has to give up 4 units of Milo.

To sketch the budget line, we can plot the points (0, I/8), (I/4, 0), and (5I/16, 3I/16) on a graph, where the x-axis represents the number of tins of Milo (M) and the y-axis represents the number of books (B). Then, we can draw a straight line connecting these points to represent Lizzy's budget line.

c. Let's assume that the lowest price of books that Lizzy will substitute for Milo is P dollars. Then, the new budget line can be written as:

4M + P(2/3)B + 20(20)S + 20(40)J = I

What is probability?

By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1.

There are two ways this can happen: either he selects an apple first and then an orange, or he selects an orange first and then an apple. We can compute the probability of each of these events separately and then add them together.

First, let's consider the probability that Preston selects an apple first and then an orange. The probability of selecting an apple first is 4/11, and then the probability of selecting an orange from the remaining 10 fruits (which includes 3 apples and 6 oranges) is 6/10. So the probability of this event is (4/11) * (6/10) = 24/110.

This can be simplified by dividing the numerator and denominator by 2:

48/110 = 24/55

So the probability that Preston selects an apple and an orange is 24/55. Therefore, the answer is m + n = 24 + 55 = 79.
