1/2 gallons of water rush down the slide each seconds.

For the given question-

Rate of running water = 1 half gallon every 3 seconds.

Rate of running water = 1 1/2 = 3/2 gallon every 3 seconds.

It means-

In every 3 seconds ----> 3/2 gallons water flows.

Thus for 1 sec, divide both side by 3.

Answer:

56

Step-by-step explanation:

Take two points as far apart on the line (for maximum accuracy), preferably on grid points, and then calculate the vertical difference divided by the horizontal difference.

So (4, 224) and (0,0) are on the line, and (224-0)/(4-0) = 56

Taking into account the definition of a system of linear equations, Finally, the investor owns 80 and 120 shares of Stock A and B respectively.

A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

A solution to a system is an assignment of values to the unknowns that makes each of the equations true. Solving a system means finding all the solutions of the system.

In this case, a system of linear equations must be proposed taking into account that:

You know:

The system of equations to be solved is:

A + B= 200

9.50A +27B= 4000

There are several methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.

In this case, isolating the variable "A" from the first equation you get:

A= 200 - B

Substituting the expression in the second equation:

9.50× (200 - B) +27B= 4000

Solving:

9.50×200 - 9.50B +27B= 4000

1900 - 9.50B +27B= 4000

- 9.50B +27B= 4000 - 1900

17.5B= 2100

B= 2100÷ 17.5

B= 120

Substituting this value in the expression A=200 - B you get:

A= 200 - 120

A= 80

Finally, the investor owns 80 shares of Stock A and 120 shares of Stock B.

The largest value less than 500 that the arithmetic progressions have in common = 479

In this question, we have been the arithmetic progressions {2,5,8,11, . . .} and {3,10,17,24, . . .}

We need to find the largest value less than 500 that they have in common.

We know that the formula for the n-th term of arithmetic progression is: an = a + (n – 1)d

For arithmetic progression {2,5,8,11, . . .}

a_m = 2 + (m - 1)3

For arithmetic progression {3,10,17,24, . . .}

a_n = 3 + (n - 1)7

if we solve for m, n then m =160 and n =69

2 + (160 -1)*3 = 479  which is the 160th term in the arithmetic progression {2,5,8,11, . . .}

3 + (69 - 1)*7  =479 which is the 69th term in the arithmetic progression {3,10,17,24, . . .}

The length of the guy wire will be equal to 27.78 feet.

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Given that Janelys places a 5-foot tall pole to support the guy wire. After placing the pole, Janelys measures the distance from the stake to the pole to be 14 ft. She then measures the distance from the pole to the tower to be 24 ft.

The length of the wire will be calculated as,

L² = 24² + 14²

L² = 576 + 196

L² = 772

L = √772

L = 27.78 ft

For the given question-

The formula for the linear velocity is given as;

Linear density; μ = mass/length

Put the values,

μ = 4.5 x 10⁻³/0.6

μ = 7.5 x 10⁻³ kg/m

The formula for the fundamental frequency is;

F = (1/2L)√(T/ μ)      

F = (1/2x0.6)√(765/ 7.5 x 10⁻³)      

F = 266.14 hz

The number of loops  is;

n = f'/f

n = 16000/266.14

We will see that the odd functions were f(x) = x5 - 3*x3 + 2*x and f(x) = 1/x since only those were true under the specified circumstances.

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a connection between inputs in which each input is connected to precisely one output. The most basic definition is that a function is a collection of ordered pairs of items, which in our instance will be numbers, but they may also be anything else, and which have the feature that their initial members are all distinct from one another. The relationship between the input or domain and the output or range is known as the function rule. If and only if there is a single value in the range for each domain value, a relation is a function.

Here,

A function is odd,

f(-x) = -f(x) for every value of x in its domain.

1) f(x) = x^3 - x^2

f(-x) = (-x)^3 - (-x)^2

= -x^3 - x^2

f(-x) ≠ -f(x)

This function is not odd.

2) f(x) = x^5 - 3*x^3 + 2*x

f(-x) = (-x)^5 - 3*(-x)^3 + 2*(-x)

= -x^5 + 3*x^3 - 2*x = -f(x)

This function is odd.

3) f(x) = 4x + 9

f(-x) = 4*(-x) + 9

= -4*x + 9

-f(x) = -( 4*x + 9)

= -4*x - 9

f(-x) ≠ -f(x)

This function is not odd.

Because only these were true under the specified circumstances, we will find that the odd functions are f(x) = x^5 - 3*x^3 + 2*x and f(x) = 1/x.

Step-by-step explanation:

sum of all angles of a triangle equal 180 degrees

so we can add all these angles together and set it equal to 180

53+(8p+10)+(2p+17)=180

hopes this helps please mark brainliest

Answer:

a)   53° + (8p + 10)° + (2p + 17)° = 180°

      p = 10

b)   53°, 90° and 37°

Step-by-step explanation:

Interior angles of a triangle sum to 180°.

Therefore, to find the value of p, equal the sum of the given angles to 180°, then solve for p.

⇒ 53° + (8p + 10)° + (2p + 17)° = 180°

⇒ 53 + 8p + 10 + 2p + 17 = 180

⇒ 8p + 2p + 53 + 10 + 17 = 180

⇒ 10p + 80 = 180

⇒ 10p + 80 - 80 = 180 - 80

⇒ 10p = 100

⇒ 10p ÷ 10 = 100 ÷ 10

⇒ p = 10

To find the measure of the angles, substitute the found value of p into the expression for each angle:

⇒ (8p + 10)° = (8(10) + 10)° = (80 + 10)° = 90°

⇒ (2p + 17)° = (2(10) + 17)° =  (20 + 17)° = 37°

Therefore, the measures of the three angles are:

The two boats will be 120 miles apart in five hours.

We need to find the time at which the boats will be 120 miles apart from each other.

It has been given that the total distance is 120 miles.

Now, let's take up the following assumptions in order to arrive at the time taken by two boats to cover the requisite distance:-

Let x= distance traveled by boat 1 at 10 miles per hour.

Let y= distance traveled by boat 2 at 14 miles per hour.

Thus, x+y=120(given)------(i) [That is, distance travelled by boat 1+ Distance travelled by boat 2= Total Distance]

Let t denote the time factor,

then, Boat 1 will travel x miles in T hours, and the Boat 2 will travel y miles in T hours.

We know, Distance= Rate * Time

Thus,  we can say, x= 10*T---------------(ii)

                               y=14*T-----------------(iii)

Adding equations ii and iii, we get

x+y=24T----------------(iv)

Now, subtracting equation (iv) from (i), we get

24T-120=0

24T= 120

thus, we get t=5

Hence, the time taken by two boats, to be 120 miles apart is five hours.

Given that the test's p-value is 0.0562>0.05, there is enough data to conclude that the machines' manufacturer should perform a new calibration.

A statistic employed in statistical hypothesis testing is known as a test statistic. A test statistic, which can be thought of as a numerical summary of a data set that condenses the data into a single value that can be used to conduct the hypothesis test, is how a hypothesis test is commonly expressed.

Here,

x=4.88 cm

μ=5 cm

σ=0.44 cm

n=49

The test statistic,

=(4.88-5)/(0.44/7)

z=-1.909

The p-value of the test is the probability that the sample mean is different by at least 4.88 - 5 = 0.12 from the target value, which is P(|z| > -1.909), which is 2 multiplied by the p-value of z = -1.909

At z=-1.909, p-value=0.0281
