the function f(h)=2d+4.3 relates the h height of the water in a function on a calculator and use the graph to find the height of the water when the pipe has a diameter of 1.5 inches.
Answers
Answer:
The height of water is 7.3 inches, when diameter of pipe is 1.5 inches.
Step-by-step explanation:
We are given the following information in the question:
[tex]f(h) = 2d + 4.3[/tex]
where f(h) is a function for height of water and d is the diameter of pipe in inches.
We have to calculate height of water when d = 1.5 inches.
Putting d = 1.5 in the above equation, we get:
[tex]f(h) = (2\times 1.50)+ 4.3 = 7.3[/tex]
Hence, the height of water is 7.3 inches, when diameter of pipe is 1.5 inches.
The attached image shows the graph for the given equation.

42 students and 6 faculty members at Byrd Middle school chose to retake their school pics .these #'s represent 1/12 of the students and 1/6 of the fuculty .what is the combined # of students and faculty members
Answers
Let s = # of students and f = # of faculty. We want to find s + f.
(1/12)s = 42. Mult. both sides by 12, we get s = 504.
(1/6)f = 6. Mult. both sides by 6, we get f = 36.
Then the total # of faculty and students combined is 504+36 = 540 (ans.)

A rectangular swimming pool has a volume of 2160 cubic feet. Water is being added to pool at a rate of about 20 cubic feet per minute. Use an equation in point-slope form to determine about how long it will take to fill the pool completely if there were already about 1200 gallons of water in the pool. Use the fact that 1 cubic foot of space holds about 7.5 gallons of water.
Answers
-> there is already 160 cubic ft. of water
y=20x+160
-> this is the equation
2160=20x+160
2000=20x
100=x
you need 100 cubic ft. more to finish filling the pool

At maximum height, v = 0, we assume [tex]g = 32 ft/s^2[/tex] then we have:
[tex]0=u^2-2(32)(49)\\ \\u^2=3,136\\ \\ u= \sqrt{3,136} =56[/tex]
Therefore, the minimum speed that the stone should be thrown so as to reach a height of 49 feet is 56 feet per second.

What is 69,000 rounded to the nearest hundred?
To round to the nearest hundred, you need to know whether the number next to hundred's place is greater than 5 or lesser than 5. If its greater than 5, you need to round up. If its lesser than 5, you need to round down.
69,000 → The number 0 is in the hundred's place. Zero has no value so thus you will be rounding down.
69,000 ≈ 69,000.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
Total puppies= 15
Puppies who opened their eyes = 11
let the number of puppies who have not open-end their eyes be c.
so, puppies have their eyes closed
c= 15 - 11

What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given,
Amount or money you earn at your job varies directly with the number of hours you work
One can earn $21.75 for 3 hours
We need to find how many hours taken to earn $145.
To find this we form an equation.
Let x be the number of hours to earn 145
21.75/3=145/x
Apply cross multiplication
21.75x=3×145
21.75x=435
Divide both sides by 21.75
x=20
Hence, it took 20 hours to earn $145.

For the moment let [tex]\displaystyle{ \cos\theta= \frac{8}{17} [/tex] (we make it positive since we are modeling using a triangle.)
Using the Pythagorean theorem, the length of the side opposite to angle [tex]\theta[/tex] is found to be 15 units.
We can see that the sine of theta is [tex]\displaystyle{ \sin\theta= \frac{opposite \ side}{hypotenuse}= \frac{15}{17} [/tex].
In the third quadrant, both sine and cosine of an angle are negative, so the actual values of the sine and cosine of theta are, eventually:
[tex]\displaystyle{ \sin\theta=- \frac{15}{17} [/tex], [tex]\displaystyle{ \cos\theta=- \frac{8}{17} [/tex].
Recall the double-angle identities (formulas):
[tex]\sin 2\theta=2\sin\theta\cos\theta[/tex], [tex]\cos2\theta=cos^2(\theta)-sin^2(\theta)[/tex].
Using these identities and the ratios found above, we have:
[tex]\displaystyle{ \cos2\theta=cos^2(\theta)-sin^2(\theta)=(- \frac{8}{17})^2-(- \frac{15}{17})^2=\frac{64}{289}-\frac{225}{289}=\frac{-161}{289}[/tex]
Similarly, applying the double angle formula for the sine we have:
[tex]\displaystyle{ \sin 2\theta=2\sin\theta\cos\theta=2\cdot(- \frac{8}{17})(- \frac{15}{17})=\frac{240}{289}[/tex]
[tex]\displaystyle{ \tan2\theta= \frac{\sin 2\theta}{\cos 2\theta}= \frac{\frac{240}{289}}{\frac{-161}{289}}= -\frac{240}{161} [/tex]
Answer:
[tex]\displaystyle{\cos2\theta=\frac{-161}{289}[/tex]
[tex]\displaystyle{ \tan2\theta= -\frac{240}{161}[/tex]

A change in x of 2 from one row to the next gives a change in y of 6. For example, changing x from -3 to -1 gives a change in y from -8 to -2. Then the slope is
... slope = ∆y/∆x = 6/2 = 3 . . . . . the coefficient of x
Now, you can pick any row of the table to determine what the intercept value must be. For example, choosing x = 1, we have
... 4 = 3×1 + intercept
... 1 = intercept . . . . . . . subtract 3 from both sides of the equation
Now, you know your equation is
... y = 3x + 1
_____
Since this is a linear equation, the y-intercept at x=0 will be halfway betweeen the value of y at x=-1 and the value of y at x=1. That is (-2+4)/2 = 1, in agreement with our calculation above.

_____ ---------
total 52
answer: 36/52
The probability that a card randomly drawn from a well-shuffled 52-card deck is not a spade or a king is approximately 0.846 or 44 out of 52.
Explanation:In a well-shuffled deck of 52 cards, there are four spades and four kings. Therefore, there are 4 + 4 = 8 cards that could be a spade or a king. The probability that a randomly chosen card is a spade or king can be calculated as the number of favorable outcomes divided by the total number of outcomes. So, the probability is 8/52 or approximately 0.154.
However, the question asks for the probability that the card is not a spade or king. To find this, we calculate 1 minus the probability of drawing a spade or king. Therefore, the probability that a card randomly drawn from a well shuffle deck is not a spade or a king is 1 - 0.154 = 0.846 or 44/52.
