Answer:

7x  + 9/10  ft

Step-by-step explanation:

To find the perimeter of a triangle, add the lengths of the three sides

P = 2x + 1/5  +  4x + 1/2  + x+ 1/ 5

Combine like terms

P = 7x + 2/5 +1/2

Get a common denominator

P = 7x + 2/5(2/2) + 1/2 * (5/5)

   = 7x + 4/10 + 5/10

   = 7x  + 9/10

Answer:

Step-by-step explanation: π = 3.142

r = 10 cm

Area of the circle = 3.142 × 10²

Area = 3.142 × 100

Area = 314.2 cm²

The area of the required circle would be 149.590 cm² which is a radius of 6.9 cm.

The area of the circle is equal to the product of the square of the radius of the circle and pi.

A = πr²

where 'r' is the radius of the circle

We have been given that the radius of a circle is 6.9 cm.

So here r = 6.9 cm

the area of a circle = πr²

the area of a circle = π(6.9)²     [take π = 3.142]

the area of a circle = (3.142)(47.61)

the area of a circle = 149.590 cm²

Hence, the area of the required circle would be 149.590 cm².

Answer:

14.1 =x

Step-by-step explanation:

Since this is right triangle, we can use trig functions

sin theta = opp/ hypotenuse

sin 42 = x /21

21 sin 42 = x

14.05174273 =x

Rounding to the nearest tenth

14.1 =x

Answer:

x = 14.1 (Rounded to the nearest tenths)

Step-by-step explanation:

Since the opposite side of the angle given needs to be found out and hypotenuse, Sin ratio would be used;

Sin(42) = \(\frac{x}{21}\)

=> Now multiply 21 on both sides of =, in order to isolate x;

Sin(42) * 21 = x

14.1 = x

Answer:

Step-by-step explanation:

Item 1:

Discount = Original price - discount price

             = 22.50 - 13.50

             = $ 9

Discount percentage = \(\frac{9}{22.50}*100\\\\\)

                                   = 40%

Discount percentage = 40%

Tax = 14.31 - 13.50 = $0.81

Tax% = \(\frac{0.81}{13.50}*100\\\\\)  = 6%

Tax percentage = 6%

Item 2:

Tax = 6% of 16.20

      = 0.06 * 16.20

      = 0.972

Tax = $ 0.97

Total price (including tax )= 16.20 + 0.97 = $ 17.17

         x = $ 17.17

Item 3:

Discount  = 40% of 32.50

                        = 0.4 * 32.50

                        = $ 13

y =  32.50 -13

y = $ 19. 50

Tax = 6% of 19.50

       = 0.06 * 19.50

       = 1.17

z = 1.17 + 19.50

Z  =$ 20.67

Based on the text, the primary source of primate endangerment today is habitat destruction.

Habitat destruction is considered the primary source of primate endangerment based on various factors mentioned in the text. Primates, like many other species, heavily rely on their natural habitats for survival, including food, shelter, and breeding. However, human activities such as deforestation, urbanization, and land conversion for agriculture or infrastructure development have significantly reduced and fragmented primate habitats.

Habitat destruction leads to the loss of critical resources and disrupts the ecological balance necessary for primate populations to thrive. As their habitats shrink, primates face increased competition for limited resources, reduced access to food and water sources, and decreased opportunities for successful reproduction and rearing of offspring. This loss of habitat also exposes primates to increased vulnerability to predation, disease transmission, and human-wildlife conflicts.

Step-by-step explanation:

The probability that an individual has a total cholesterol level between 200 and 250 is calculated to be approximately 0.5020 or 50.2%.

To solve this problem, we need to find the z-scores corresponding to the lower and upper bounds of the cholesterol range, and then find the area under the normal distribution curve between these z-scores.

First, we calculate the z-score for 200:

z1 = (200 - 219) / 41.6 = -0.455

Next, we calculate the z-score for 250:

z2 = (250 - 219) / 41.6 = 0.746

Now we can use a standard normal distribution table or calculator to find the area between these two z-scores:

P(-0.455 < Z < 0.746) ≈ 0.5020

This means that the probability that an individual has a total cholesterol level between 200 and 250 is approximately 0.5020 or 50.2% (rounded to one decimal place).

Answer: The given vector can be expressed as a linear combination of u, v, and w as (14, 9, 14) = u - v + 3w.

Question: Express the following as a linear combination of u =(3, 1,6), v = (1.-1.4) and w=(8,3,8). (14, 9, 14) = ____ u- _____ v+ _____

Current Progress: To express the given vector as a linear combination of u, v, and w, we need to find scalars a, b, and c such that (14, 9, 14) = a*u + b*v + c*w.

Step 1: Write the equation in component form:
(14, 9, 14) = (3a + b + 8c, a - b + 3c, 6a + 4b + 8c)

Step 2: Equate the corresponding components and solve for a, b, and c:
3a + b + 8c = 14
a - b + 3c = 9
6a + 4b + 8c = 14

Step 3: Solve the system of equations using any method (substitution, elimination, etc.). One possible solution is a = 1, b = -1, and c = 3.

Step 4: Plug the values of a, b, and c back into the linear combination equation:
(14, 9, 14) = 1*u + (-1)*v + 3*w

Step 5: Simplify the equation:
(14, 9, 14) = u - v + 3w

Answer: The given vector can be expressed as a linear combination of u, v, and w as (14, 9, 14) = u - v + 3w.

This means that there is a 65.54% probability that a student in ECO 20150 will get a 72 or higher on the final exam.

To calculate the probability that a student gets a 72 on the final exam, we need to find the area under the normal distribution curve from 72 to infinity. We can use the standard normal distribution table (also known as the Z-table) to find this probability.

First, we need to convert the raw score of 72 to a Z-score. The Z-score tells us how many standard deviations a raw score is above or below the mean. To convert a raw score to a Z-score, we use the following formula:

Z = (X - μ) / σ

Where X is the raw score, μ is the mean, and σ is the standard deviation.

Plugging in the values from the problem, we get:

Z = (72 - 67) / 11 = 0.45

Now that we have the Z-score, we can look it up in the standard normal distribution table to find the probability. The probability is the area under the curve from the Z-score to infinity. In this case, the probability is 0.6554, or about 65.54%.

Chen burned 9,912 calories in total from swimming last month.

The quantity of energy that may be used as fuel by our bodies comes in the form of calories, which are a unit of measurement.

By measuring the quantity of heat energy emitted when the meal or drink is burned in a calorimeter, one may quantify the number of calories in various foods and beverages.

We know that Chen burns 354 calories in 1 hour of swimming. So, to find out how many calories he burned in 28 hours, we need to multiply 354 by 28:

Calories burned in 28 hours = 354 calories/hour × 28 hours

= 9,912 calories

This is because isosceles triangle having two sides that are equal in length, and have 50° angle, which is acute angle, that is less than 90°. This state that the remaining angle in the triangle must also be acute triangle, as the sum of all angles in a triangle must equal 180°.

This means that the remaining angle must be 80° (i.e. 180 - 50 = 80). An isosceles triangle is triangle consisting of  two sides of equal length and two angles of equal measure.

The percentage of the original area of wetlands currently left in the United States is approximately 50%.

Wetlands are regions of land where the soil is continually or intermittently soaked with water. Wetlands have a particular hydrology, soil, and vegetation mix that results in specialised ecosystems that offer a variety of ecological functions.

There are many different types of habitats where wetlands can be found, such as coastal locations, interior regions, and high-altitude mountain regions. They come in a variety of shapes, such as marshes, swamps, bogs, fens, and estuaries, and can be freshwater, brackish, or saline.

Wetlands are significant for several reasons. For species, such as migrating birds, amphibians, and fish, they offer crucial habitats. They also aid in removing contaminants from water, lessen the effects of flooding, and give people access to recreational activities. Wetlands are crucial for carbon sequestration as well.
