Answer:
233445.54 gallons
Step-by-step explanation:
Given data
Diameter= 15m
Radius= 7.5m
Height= 5m
Let us first find the volume
the volume of a cylinder is given as
V= πr^2h
substitute
V= 3.142*7.5^2*5
V= 3.142*56.25*5
V=883.6875 m^3
Hence the volume in gallons is
233445.54 gallons (from conversion tables)
If there are 19 questions and each question has 4 answers, what is the probability she will answer at least one question correctly?
Answer:
0.9958
Step-by-step explanation:
P(being correct) = 1/4 = 0.25
Hence, p = 0.25
n = 19
P(x ≥ 1) = p(x = 1) + p(x = 2) +... + p(x = 19)
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
However, to save computation time, we could use a calculator :
Using a calculator,
P(x ≥ 1) = 0.99577
P(x ≥ 1) = 0.9958

Answer:
Were you looking for the x and y intercepts? The question is very misleading.
If you were the x intercepts are (4-√2,0), (4+√2,0)
And the y intercept is (0,−14)

Answer:
[tex]x=4-\sqrt{2}[/tex] or [tex]x=4+\sqrt{2}[/tex]
Step-by-step explanation:
Plug in given values of a, b, and c into the quadratic formula and solve for x:
[tex]x=\frac{-b±\sqrt{b^{2}-4ac } }{2a}[/tex]
[tex]x=\frac{-8±\sqrt{8^{2}-4(-1)(-14) } }{2(-1)}[/tex]
[tex]x=\frac{-8±\sqrt{64-56 } }{-2}[/tex]
[tex]x=\frac{-8±\sqrt{8} }{-2}[/tex]
[tex]x=\frac{-8±2\sqrt{2} }{-2}[/tex]
[tex]x=4±-\sqrt{2}[/tex]
Therefore, the roots are [tex]x=4-\sqrt{2}[/tex] or [tex]x=4+\sqrt{2}[/tex]

Answer:
[tex]\frac{x^{2} }{3600} - \frac{y^{2} }{121} = 1[/tex]
Step-by-step explanation:
Since the hyperbola opens left and right with a center at the origin, then
[tex]\frac{x^{2} }{^{2} } - \frac{y^{2} }{b^{2} } = 1[/tex]
In the graph a = 60 and b = 11
So
[tex]\frac{x^{2} }{60^{2} } - \frac{y^{2} }{11^{2} } = 1[/tex].
[tex]\frac{x^{2} }{3600} - \frac{y^{2} }{121} = 1[/tex]

Constant of proportionality=
Answer:
The constant of proportionality between 'y' and 'x' in the graph is 0.75
Step-by-step explanation:
The constant of proportionality is the constant ratio between two quantities that are directly proportional.
When two quantities are directly proportional, then a percentage increase in one of the quantities will result in an equal percentage increase in the other quantity, and the two quantities are therefore, increasing at the same rate to each other
From the graph we have;
When x = 0, y = 0, all graphs of directly proportional relationships have x = 0 when y = 0
However;
When x = 2, y = 1.5
When there is an 100% increase, we have;
When x = 2 + 100/100 ×2 = 4, y = 1.5 + + 100/100 ×1.5 =3
Therefore, when x = 4, y = 3
The constant of proportionality = The ratio between each 'y' and 'x' value
∴ The constant of proportionality = y/x = 1.5/2 = 3/4 = 0.75
Therefore;
The constant of proportionality between 'y' and 'x' in the graph = 0.75.

Mrs. Ortiz measured the outside temperature at noon as -2°F. Later that
day, she measured the temperature as -5°F. Write an inequality that
correctly compares -2 and -5. Then explain the meaning of the inequality
for the situation. 6.NS.7, 6.NS.7b
Answer:
-2°F>-5°F
Step-by-step explanation:
-2°F is greater than -5°F
This also means the first time Mrs. Ortiz measured the outside tempurature it was hotter than the second time she measured it.

I really need help on this
Answer:
I think the answer is 4800.
Step-by-step explanation:
Usually people would use 1/10 or anything like that, but here 3/7 was used. in order to find 10 percent you would divide by 10, correct, well I did the same with 7. (because you must find 1/7) The question was 3/7, so I multiplied 1400 by 3, and my answer was 4800. (sorry if this wasn't understandable, im the the best at explaining things)

()) There are two cubes. The first cube has a volume of 1,000 cubic units. The second cube is smaller than the first, with sides only half as long. What is the volume of the second cube? D) cubic units Submit
Answer:
125 units^3
Step-by-step explanation:
Volume is l*w*h = V. A cube has all equal sides so wecan divide 1000 by 3 and get our side lengths.
You then divide the sides by 2 because the question says the second cubes sides are half the size
5*5*5 = 125
The volume of the second cube is 125 units³.
What is volume?In mathematics, ‘Volume’ is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.
Given that a cube has volume 1000 units³ and another smaller cube has smaller volume has side only half as long.
We need to find the volume of the second cube,
So, let the side of the first cube be x,
We know that the volume of a cube = side³
Therefore,
x³ = 1000
x = ∛1000
x = 10 units
Therefore, the second cube will have a side of 10/2 = 5 units
Volume of second cube = 5³ = 125 units³.
Hence the volume of the second cube is 125 units³.
