Set up a system of equations

Answer: r = 45°

Step-by-step explanation:

All triangles angles add up to 180 degrees.

With that said we can use the given information and create an equation to solve.

55° + 80° + r = 180°

Lets solve for r.

55° + 80° + r = 180°

first lets combine like terms.

135° + r = 180°

now lets subtract 143° from both sides

135° + r = 180°

-135°       -135°

r = 45°

10 to the 9th power is 10 times 10 to the 8th power.

The rate at which water is being pumped into the tank is 11,760 cm3/min.

          V = (1/3)πr2h

          Using similar triangles:

          (r / 2) = (2 / 6)

          r = 2/3 * 4r = 8/3 cm

          dV / dt = (πr2 / 3)dh / dt

         dV / dt = pump rate - leak rate

      = pump rate - 10,500 cm3/mindh / dt

      = 20 cm/minr = 8/3 cm

        pump rate - 10,500 = (π(8/3)2 / 3) * 20pump rate - 10,500

     = 2114.67pump rate

     = 11,760 cm3/min

Therefore, the rate at which water is being pumped into the tank is 11,760 cm3/min.

It represents a relationship between two sets of numbers in which each input has exactly one output. A function can be expressed symbolically, graphically, or verbally and is used to model real-world phenomena, solve equations, and make predictions in various fields of study.

According to the given information

To find g(-7) and f(-7), we need to substitute -7 for y in the function g(y) = -2ᵇ - 4b + 13 and x in the function f(x) = -2x² - 4x + 13.

g(-7) = -2⁻⁷ - 4⁻⁷ + 13

The correct equation for the hanger balance is:= w = 2

How to balance equations?

The hanger balance equation is typically used in physics experiments to determine the weight of an object by comparing it to known weights on the other side of a balance. The equation is based on the principle of equilibrium, which states that the sum of the forces acting on an object must be zero for it to remain stationary.

The correct equation for the hanger balance is:

w = 2

This equation simply states that the weight of the object being measured (represented by "w") is equal to a known weight of 2 units. This indicates that the object being measured has a weight of 2 units.

The other equations provided, such as "6 = w + 2" and "6 = w - 2", do not accurately represent the hanger balance equation because they do not take into account the known weight on the other side of the balance. In order to determine the weight of an object using a hanger balance, it is necessary to have a known weight on the other side of the balance to compare it to.

In summary, the correct equation for the hanger balance is w = 2, which represents the weight of the object being measured as 2 units.

Answer:

2/5 or 0.4, which is also equivalent to a 40% chance.

Step-by-step explanation:

To determine the theoretical probability of drawing a prime number from the numbers 2 through 16, we need to first identify the prime numbers in this range. The prime numbers between 2 and 16 are 2, 3, 5, 7, 11, and 13.

There are a total of 15 numbers in the hat, and 6 of them are prime. Therefore, the probability of drawing a prime number can be calculated as:

Probability of drawing a prime number = Number of favorable outcomes / Total number of possible outcomes

Number of favorable outcomes = 6 (since there are 6 prime numbers in the range of 2 through 16)

Total number of possible outcomes = 15 (since there are 15 numbers in the hat)

So, the probability of drawing a prime number is:

Probability of drawing a prime number = 6 / 15

Simplifying this fraction by dividing both numerator and denominator by 3, we get:

Probability of drawing a prime number = 2 / 5

Therefore, the theoretical probability of drawing a prime number from the numbers 2 through 16 is 2/5 or 0.4, which is also equivalent to a 40% chance.

If the sample size is large and the probability of success is not too close to 0 or 1, using the normal distribution to approximate the binomial probability will generally give a more accurate answer than using the binomial tables. However, if the sample size is small or the probability of success is very close to 0 or 1, using the binomial tables may be more accurate.

If the sample size is large (typically, n ≥ 30) and suppose that the probability of success (p) is not too close to 0 or 1, then we can use the normal distribution. As it gives more approximate value to the binomial probability which will generally give a more accurate answer than using the binomial tables.

This is because the normal distribution provides a more precise approximation of the binomial distribution as the sample size increases.

However, if the the probability of success is very close to 0 or 1 or sample size is small then using the binomial tables to calculate the probability directly may be more accurate.

A confounding variable is any variable that influences the dependent variable or response variable and is also

correlated with the independent variable. Because it is difficult to determine which variable is causing changes in the

dependent variable, it is also known as a confounding variable.

In other words, a confounding variable is a variable that can affect the dependent variable in an experiment, making it

impossible to determine the relationship between the independent variable and the dependent variable.

Therefore, when a confounding variable is present in an experiment, one cannot tell whether the results were due to

Answer:

Therefore, the time for the return trip is:

≈ 5.306 seconds

Step-by-step explanation:

Let's start by finding the speed of the boat. We know that the boat travels 400m at a constant speed, so we can use the formula:

Speed = Distance / Time

Speed = 400m / Time (for one-way trip)

Let's assume that the time for the one-way trip is t. Then we can rewrite the speed formula as:

Speed = 400m / t

Now let's find the time for the return trip. We know that the boat travels the same route at the same speed for 2 minutes, which is equivalent to 120 seconds. This means that the distance traveled on the way back is:

Distance = Speed x Time

Distance = (400m / t) x 120 seconds

Distance = 48000m / t

We also know that when Pilar increases the boat's speed by 10 m/min, the return trip is 60 seconds faster. This means that the time for the return trip is:

t - 60 seconds

Using the same formula as before, the distance traveled on the return trip is:

Distance = (400m / (t + 1/2)) x (t - 60) seconds

Distance = (400m / (t + 1/2)) x (t - 60/60) minutes

Distance = 400m x (t - 60/60) / (t + 1/2) minutes

Now we know that the distance traveled on the way back is equal to the distance traveled on the way there:

48000m / t = 400m x (t - 60/60) / (t + 1/2)

Simplifying this equation, we get:

48 / t = 4 x (t - 1/3) / (t + 1/2)

Multiplying both sides by (t + 1/2), we get:

48(t + 1/2) / t = 4(t - 1/3)

Simplifying this equation, we get:

96 / t = 4t - 4/3

Multiplying both sides by t, we get:

96 = 4t^2 - 4/3t

Multiplying both sides by 3, we get:

288 = 12t^2 - 4t

Rearranging this equation, we get

12t^2 - 4t - 288 = 0

Dividing both sides by 4, we get:

3t^2 - t - 72 = 0

Using the quadratic formula, we can solve for t:

t = [1 ± sqrt(1 + 4(3)(72))] / 6

t = [1 ± sqrt(865)] / 6

Since t must be positive, we take the positive root:

t ≈ 6.366

Therefore, the time for the return trip is:

t - 60 seconds ≈ 6.366 - 60 seconds ≈ 5.306 seconds

The length of the pole is approximately 412.7 feet.

What is the tangent function?

The tangent function is a mathematical function that relates the ratio of the length of the side opposite to an acute angle in a right triangle to the length of the adjacent side. It is defined as the ratio of the sine of the angle to the cosine of the angle.

We can solve this problem using trigonometry. Let's call the length of the pole "x". We can then use the tangent function to relate the angle that the pole makes with the vertical to the length of the shadow cast by the pole.

The tangent of the angle between the pole and the vertical is equal to the opposite side (length of the shadow) divided by the adjacent side (length of the pole).

tan(7°) = opposite / adjacent

tan(7°) = 49 / x

We can solve for x by multiplying both sides by x and then dividing both sides by tan(7°):

x = 49 / tan(7°)

Now we know the length of the pole is:

x = 49 / tan(7°) = 412.7 ft (rounded to one decimal place)

Therefore, the length of the pole is approximately 412.7 feet.
