No, this triangle is NOT a right angle.

Step-by-step explanation:

The known fact is that the largest number is our hypotenuse. The other two numbers can go on either side.

A square plus B square equal C square is our equation

Let's plug in the numbers: 15^2+5^2=16^2

Now we solve.

Once we solve our squares and add them together, we get 250=256. Since these two number are not equal to each other, this triangle is NOT a right angle

a tank in the shape of a hemisphere has a diameter of 6 feet. if the liquid that fills the tank has a density of 53.3 pounds per cubic foot, what is the total weight of the liquid in the tank, to the nearest full pound?

Answers

The total weight of the liquid in the tank, to the nearest full pound, is calculated to be 3,012 pounds.

The volume of a hemisphere with diameter 6 feet is (2/3) x π x (6/2)³ = 56.55 cubic feet.

The weight of the liquid in the tank can be found by multiplying the volume of the liquid by its density:

Weight = Volume x Density = 56.55 x 53.3 = 3,012.32 pounds.

Rounding this to the nearest full pound gives a total weight of 3,012 pounds. Therefore, the total weight of the liquid in the tank is 3,012 pounds (to the nearest full pound).

Suppose an earthquake can be felt up to 76 miles from its epicenter. You are located at a point 65 miles west and 40 miles south of the epicenter. Do you feel the earthquake?

Answers

The distance between your location and the epicenter is just slightly larger than the maximum distance that the earthquake can be felt (76 miles), so you would be able to feel the earthquake.

What is triangle?

A triangle is a polygon with three sides and three angles. The sum of the angles in a triangle is always 180 degrees. There are different types of triangles such as equilateral, isosceles, scalene, right-angled, obtuse-angled, and acute-angled triangles. Triangles are used in geometry and other fields of mathematics to solve problems related to areas, angles, and side lengths.

Here,

Yes, you feel the earthquake.

To see why, imagine drawing a circle around the epicenter with a radius of 76 miles. This circle represents the maximum distance that the earthquake can be felt. Then, draw a line from the epicenter to your location. This line represents the distance between you and the epicenter.

To determine whether you feel the earthquake, we need to calculate the distance between your location and the epicenter using the Pythagorean theorem:

distance = √(65² + 40²)

distance ≈ 76.06 miles

The total surface area of each figure are:

1)  2,557.3 yd²

2) 601.02 m₂

3) 3782.5 mm²

4)750 in²

How to find the total surface area?

1) The total surface area of a cylinder is:

2πrh + 2πr².

where:

r is radius

h is height

Thus:

TSA = 2π(11 * 26) + 2π(11)²

TSA = 2π(286) + 2π(121)

TSA = 2π(407)

TSA = 2,557.3 yd²

2) The total surface area is:

2(¹/₂ * 9 * 11.12) + (16 * 15) + (16 * 12) + (9 * 16)

= 25.02 + 240 + 192 + 144

= 601.02 m₂

3) The total surface area of a cylinder is:

2πrh + 2πr².

where:

r is radius

h is height

Thus:

TSA = 2π(14 * 29) + 2π(14)²

TSA = 2π(406) + 2π(196)

TSA = 2π(602)

TSA = 3782.5 mm²

4) The total surface area of the pyramid is:

TSA = (15 * 8) + (21 * 17) + (21 * 15) + (8 * 21)

Harrison expanded the square flower garden in his backyard. He made one side 3 feet longer and the other side 6 feet longer. The expanded rectangular flower garden has an area of 148 square feet. Use the drop-down menus to write an equation to model this situation

Answers

The equation to model the situation given in the question is (x+3)(x+6) = 148.

Let's assume that the original length and width of the square flower garden were "x". When Harrison expanded the garden, the new length became "x+3" and the new width became "x+6".

The area of a rectangle is given by the formula A = L × W, where A is the area, L is the length, and W is the width. Therefore, the area of the expanded rectangular flower garden is:

A = (x+3)(x+6)

We know that the area of the expanded rectangular flower garden is 148 square feet. So we can set up an equation:

(x+3)(x+6) = 148

{When we solve this equation using the quadratic formula we get x values:

x ≈ 8.2 and x ≈ -17.2 but we know x is the side of the garden so it cannot be negative, therefore, x = 8.2 unit}

This is the equation that models the situation described in the problem.

Therefore, the equation to model this situation is (x+3)(x+6) = 148.

Answers

Given a sample of 36 male mosquitos of a species with a mean lifespan of 8.88 days and a standard deviation of 6.66 days, the probability of the sample mean lifespan exceeding 10 days is approximately 0.14. So, the correct choice is option B is P ( x ˉ > 10 ) ≈ 0. 14 P( x ˉ >10)≈0. 14P, left parenthesis, x, with, \bar, on top, is greater than, 10, right parenthesis, approximately equals, 0, point, 14.

The sampling distribution of the mean lifespan is approximately normal due to the Central Limit Theorem.

The standard error of the mean is 6.66 / sqrt(36) = 1.11. The z-score for a sample mean of 10 is (10 - 8.88) / 1.11 = 1.08. Using a standard normal distribution table or calculator, the probability of a z-score greater than 1.08 is approximately 0.14.

a cab was involved in a hit and run accident at night. two cab companies, the green and the blue, operate in the city. 85% of the cabs in the city are green and 15% are blue. a witness identified the cab as blue. the court tested the reliability of the witness under the same circumstances that existed on the night of the accident and concluded that the witness correctly identified each one of the two colors 80% of the time and failed 20% of the time. what is the probability that the cab involved in the accident was blue rather than green knowing that this witness identified it as blue?

Answers

From Bayes' Theorem, an events related to involved in a hit and run accident at night. The required probability that the blue cab involved in accident rather than green as well as witness also identified it as blue cab is equals to the 0.41 or 41% .

Bayes' Theorem states that the conditional probability of an event, is based on the occurrence of another event, is equal to the likelihood of the second event the first event multiplied by the probability of the first event. According to scenario, it is found that a cab was involved in a hit and run accident at night. Number of cab companies operates in city = 2 ( blue and green)

Probability that green cab involved in accident, P(G) = 85% = 0.85

Probability that blue cab involved in accident, P( B) = 15% = 0.15

Now, the cab which is identified by witness was a blue cab and after identification court also tested the witness's credibility. Here, probability that witness is correct to identification a blue cab = P(W/B) = 0.80

Probability that witness is wrong to identify the blue cab = P(W/G)

= 0.20

Using the Baye's theorem, Probability that accident was caused by blue cab provided witness identifies is, [tex]P( B/W) = \frac{ P(B ∩W )}{ P( W)} = \frac{ P( B) P( W/B)}{ P( W)} \\ [/tex]

Total Probability, P(W) = P(B)P(W/B) + P(G)P(W/G)

= 0.15 × 0.8 + 0.85 × 0.2 = 1.2 + 1.7 = 2.9

P(B/W) = (0.15 × 0.8)/2.9

= 1.2/2.9 = 0.41 = 41%

Hence, required probability value is 41%.

17. Kade has $40 in savings and wants to purchase a video game console that costs $250 plus
8.25% sales tax. Kade wants to wait until he has enough in savings to cover the purchase. If Kade
saves $50 each week, what is the minimum number of weeks Kade should wait before making his
purchase?
A. 3 weeks
B. 4 weeks
C. 5 weeks
D. 7 weeks

Answers

The minimum number of weeks Kade should wait before making his purchase is 5 weeks.

Given that, Kade has $40 as his saving, and he wants to buy a video game console that costs $250 plus 8.25% sales tax.

He saves $50 each week to buy the same, we need to find the number weeks in which he can buy the game,

Total cost of the game = 250 + 250 × 8.25%

= 250 + 250 × 0.0825

= 250 + 20.625

= 270.625

Hence, he needs to save = $270.625 - $40 = $230.625

Let the number of weeks be x,

∴ 50x = 230.625

x = 4.61 ≈ 5

Hence, the minimum number of weeks Kade should wait before making his purchase is 5 weeks.

Sammie’s Deli sells sandwiches that can be made with the ingredients listed on the board below. What is the probability that a customer will choose a sandwich on white bread with ham and either provolone or American cheese?
A- 1/6
B- 1/3
C- 1/4
D- 1/2

Answers

the probability of a customer choosing a sandwich on white bread with ham and either provolone or American cheese is 6/36, which simplifies to 1/6. Thus, option A is correct.

What is the probability?

There are 3 bread options, 4 meat options, and 3 cheese options listed on the board, which gives us a total of  [tex]3 \times 4 \times 3 = 36[/tex] possible sandwich combinations.

There are two cheese options that meet this criteria, so we can create two different sandwiches: one with provolone and one with American cheese.

Each of these sandwiches can be made in [tex]3 \times 1 \times 1 = 3[/tex] ways, as there are 3 bread options but only one option each for the ham and cheese. So, the total number of sandwich combinations that meet our criteria is [tex]2 \times 3 = 6.[/tex]

Therefore, the probability of a customer choosing a sandwich on white bread with ham and either provolone or American cheese is 6/36, which simplifies to   [tex]1/6[/tex].

What is the chord of a circle?

In Mathematics and Geometry, the chord of a circle can be defined as a line segment that typically join any two (2) points on a circle. This ultimately implies that, a chord simply refers to the section of the line that is used for connecting two (2) separate points on a circle such as line GF.

What is a secant line?

In Mathematics and Geometry, a secant line can be defined as a type of line that intersects the edge of a circle twice i.e it goes through the interior of the circle twice and intersects its boundary twice such as line HF.

In conclusion, a tangent line is a type of line that lies outside of a circle and intersects the edge of a circle exactly once i.e it touches the outside of the circle only once such as line GJ.

An aircraft (at Z) is spotted by two observers (at X and Y) who are L = 1850 feet apart. As the airplane
passes over the line joining them, each observer takes a sighting of the angle of elevation to the plane,
as indicated in the figure. If A=25°, and B=25°, how high is the airplane?

Answers

Answer: We can use trigonometry to solve this problem. Let's call the height of the airplane H, and let's call the distance from observer X to the airplane D. Then the distance from observer Y to the airplane is L - D.

From the point of view of observer X, we can write:

tan(A) = H / D

tan(25°) = H / D

From the point of view of observer Y, we can write:

tan(B) = H / (L - D)

tan(25°) = H / (L - D)

We now have two equations with two unknowns (H and D). We can solve for one of the unknowns in terms of the other, and then substitute that expression into the other equation to eliminate one of the unknowns.

Let's solve the first equation for D:

D = H / tan(25°)

Substituting this expression for D into the second equation, we get:

tan(25°) = H / (L - H / tan(25°))

Multiplying both sides by (L - H / tan(25°)), we get:

tan(25°) (L - H / tan(25°)) = H

Expanding the left-hand side, we get:

tan(25°) L - H = H tan^2(25°)

Adding H to both sides, we get:

tan(25°) L = H (1 + tan^2(25°))

Dividing both sides by (1 + tan^2(25°)), we get:

H = (tan(25°) L) / (1 + tan^2(25°))

Now we can substitute this expression for H into the equation D = H / tan(25°) to get:

D = ((tan(25°) L) / (1 + tan^2(25°))) / tan(25°)

Simplifying, we get:

D = L / (1 + tan^2(25°))

Now that we know the distance D, we can use the equation tan(A) = H / D to find H:

tan(25°) = H / D

H = D tan(25°)

Substituting D = L / (1 + tan^2(25°)), we get:

H = (L / (1 + tan^2(25°))) tan(25°)

Plugging in the given values L = 1850 feet and A = B = 25°, we get:

H = (1850 / (1 + tan^2(25°))) tan(25°)

H ≈ 697.3 feet

Therefore, the airplane is about 697.3 feet high.
