Answer:

∠ CEA = 61°

Step-by-step explanation:

The measure of a chord- chord angle is half the sum of the measures of the arcs intercepted by the angle and its vertical angle, thus

∠ CEA = \(\frac{1}{2}\)(AC + BD) = 0.5(87 + 35)° = 0.5 × 122° = 61°

The spinner has a total of 6 possible outcomes, and each outcome has a different probability of occurring. To find the probability of an outcome, we divide the number of ways that outcome can occur by the total number of possible outcomes.

The possible outcomes and their frequencies are:

2 appears once

6 appears twice

8 appears three times

Therefore, the probabilities of the different outcomes are:

P(2) = 1/6 = 0.1667 or approximately 16.67%

P(5) = 0/6 = 0 or 0%

P(6) = 2/6 = 0.3333 or approximately 33.33%

P(8) = 3/6 = 0.5 or 50%

Note that the sum of all the probabilities must equal 1, since one of the outcomes must occur. In this case, 0.1667 + 0 + 0.3333 + 0.5 = 1, so we can be confident that we have calculated the probabilities correctly.

Probability is a branch of mathematics that deals with the study of random events and their outcomes. It is concerned with predicting the likelihood of a particular event occurring based on the available information.

In probability, an event is a set of outcomes, and the probability of an event is a number between 0 and 1 that indicates the likelihood of the event occurring. A probability of 0 means that the event is impossible, while a probability of 1 means that the event is certain.

In order to calculate probabilities, we need to identify the possible outcomes of an event and determine how likely each outcome is. The sum of the probabilities of all possible outcomes must always equal 1.

In the example given, the spinner has six possible outcomes, and each outcome has a different probability of occurring. By dividing the number of ways each outcome can occur by the total number of possible outcomes, we can calculate the probability of each outcome.

Probability is used in many fields, including statistics, finance, and science. It is an important tool for decision-making and risk analysis, and it can help us to make predictions about future events based on past data.

Answer:

228

Step-by-step explanation:

[Formulas Below]

Surface area means the sum of all the shapes on the figure, which means we have to calculate each area of the shapes on the triangular right prism and add them up. To calculate the triangles, we plug in 6 and 5 and get 15. Since there are 2 triangles, we multiply it by 2. Next, we have to find the areas of the rectangles. 11 * 6.5 = 71.5 (There are two of them so you multiply by 2), and 11 * 5 = 55. Finally, we add all of these up. 15 * 2 + 71.5 * 2 + 55 = 30 + 55 + 143 = 228. The surface area is 228.

Area of Triangle = (Length * Height)/2

Area of Rectangle = Length * Width

The total distances you traveled to reach your destination on each day of your three-day trip are as follows:

a) Day 1 = 40 miles

b) Day 2 = 30 miles

c) Day 3 = 11 miles.

The total distances are determined using proportions.

Proportion refers to the fractional value of the whole number or quantity.

a) Day 1:

The fractional distance traveled = ⁵/₈

The remaining distance to travel = 15 miles

15 miles = ³/₈ (1 - ⁵/₈)

Proportionately, the total distance = 40 miles (15 ÷ ³/₈)

b) Day 2:

The distance traveled = 18 miles

The remaining distance to travel = ²/₅

The distance traveled = ³/₅ (1 - ²/₅)

³/₅ = 18 miles

Proportionately, the total distance = 30 miles (18 ÷ ³/₅)

c) Day 3:

The distance traveled = ⁵/₁₁

The distance to travel = 6 miles

The distance to travel in fractions = ⁶/₁₁ (1 - ⁵/₁₁)

Proportionately, if 6 miles = ⁶/₁₁, the total distance = 11 miles (6 ÷ ⁶/₁₁)

Answer:

The value of y is \(-1.33...\)

Step-by-step explanation:

WKT, the given equation is  \(\frac{-1}{2} =\frac{3}{8} y\)

Here, y is a variable.

Now, to solve the equation,

we need to multiply \(\frac{8}{3}\)  on both sides of the given equation, in order to get the values of y.

That is, \(\frac{-1}{2}\) × \(\frac{8}{3} =\frac{8}{3}\) × \(\frac{3}{8} y\)

⇒\(-\frac{1}{2}\) × \(\frac{8}{3}= y\)

⇒\(-\frac{8}{6}=y\)

⇒\(y=-\frac{4}{3}\)

or \(y=-1.333\)

Therefore, the value of y is \(-1.33...\).

Answer:

The other possible angles would be 90º (Right tringles always have a 90º angle) and 50º

Step-by-step explanation:

To find the 3rd angle (the 50º one) all tringles angles add up to 180º. Since you already have 40º and 90º

you would subtract those from 180.

180º - 40º - 90º = 50º

Answer:

5

Step-by-step explanation:

When multiplied we get 52,145.83413. If we count, we see that five numbers are to the right of the decimal place.

Answer:

1) width = 10 + 2x

length = 20 + 2x

2) area = (10 + 2x)(20 + 2x)

= 4(5 + x)(10 + x)

3) 4(5 + x)(10 + x) = 600

(5 + x)(10 + x) = 150

50 + 15x + x^2 = 150

x^2 + 15x - 100 = 0

(x - 5)(x + 20) = 0

x = 5 feet

The width of the walkway is 5 feet.

Answer:

To find the scalar value, simply choose one side of D and one did of D’ and divide them to find the scalar. We can verify that we have the correct scalar by performing this division on each related edge. Below I will do D to D’ represented like D/D’:

4.8 / 1.2 = 4

5.2 / 1.3 = 4

3.6 / x = 4

Knowing that the scaling for each edge is 4, we can solve for x.

3.6 / 3 = x

1.2=x

So we know the edges for D are 4.8, 5.2, and 3.6 respectively to D’ scaled by 1/4. So we can determine that the edges for D’ are 1.2, 1.3, and 1.2 respectively to D scaled by 4.

So if we go D’ to D, we scale by 4. If we go D to D’, we scale by 1/4.
