Group of answer choices
Yes, they both have a volume of 339.12 inches cubed.
No, the right circular cylinder has a volume of 339.12 inches cubed and the oblique cylinder has a volume of 1 comma 356.48 inches cubed.
No, the right circular cylinder has a volume of 1 comma 356.48 inches cubedand the oblique cylinder has a volume of 339.12 inches cubed.
Yes, they both have a volume of 1 comma 356.48 inches cubed.
Answer:
Yes, they both have a volume of 339.12 inches cubed.
Step-by-step explanation:
To calculate the volume of an oblique cylinder is very simple, we must multiply π (Pi = ~ 3.14) by the radius to the power of two and then multiply by the height. In this case the height forms a 90 degree angle from the opposite base to the position of the base, but outside of it.
Volume = π × Radius² × Height
The formula for the volume of a regular cylinder or an oblique cylinder is the same, if we imagine a stack of poker chips (forming a cylinder), even when we tilt the chips to one side (forming an oblique cylinder) the volume remains the same.
Now using this information, we must find the volumes of both cylinders.
For the oblique cylinder:
Given
Using the formula,
The volume would be 339.29 m³
Now solving for the other cylinder:
V=πr²h=π·32·12≈339.29201
Rounded, the answer would be 33.29 m³
This therefore proves that they both have the same volume.

8t −15 = 32t

Step-by-step explanation:

Group the terms then subtract:
=>8t-32t=15
=>-24t=15
Divide both sides by -24:
[tex] \implies \rm \cfrac{ - 24t}{ - 24} = \cfrac{15}{ - 24} [/tex]
[tex] \rm \implies \: t = \cfrac{ - 5}{8} [/tex]

Answer:

Step-by-step explanation:
The number of dollars more is the price of 8 bottles of Brand B than the price of 8 bottles of Brand A oil is:
$ 48
Step-by-step explanation:
Brand A--

The function that represents the relation between the price of the bottles and the number of bottles is:
y=11x
Brand B--
Also, the price of the bottles depending on the number of bottles is:
Y=17x
According to Brand A the price of 8 bottles is: y=11×8=$ 88
and according to Brand B the price of 8 bottles is: y=17×8= $ 136
Also, the difference in the price of Brand B to that of Brand A for 8 bottles is:
$ 136-$ 88
= $ 48

There are no choices. The question stated choose the polynomial which means it should have choices.
Correct me if I'm wrong though. Hope you won't be offended.
Answer:
Please read explanation... it always helps... trust me...
Step-by-step explanation:
alrighty sooo....
when a polynomial is written in standard form that means that the exponents are in order from greatest to least.... (i hope that isn't confusing....)
here is an example:
x^6 + x^5 + x^2 + 23 --> this polynomial is in standard form because the exponents are in order from least to greatest..... 6 then 5 then 2 then 1

What is the equation of a line that has an x-intercept of 5 and a slope of 4?
Answer:
y=4x-20
Explanation:
Since we already have a slope, all we need to do is just find the y-intercept. To do this we can make an XY t-chart.
Using the chart we can see that for every x that decreases, a y decreases 4 times. So if we subtract 5 from x, we will multiply 5 times y. Note that this graph is increasing so the y-intercept is negative. -5 · 4 = -20
X | Y
6 | 4

Which of the following represents the translation of R (-3, 4) along the vector

Pls help lol
By applying concepts of linear algebra, the point P'(x, y) = (-3, 4) represents the translation of P(x, y) = (-3, 4) along the vectors <7, -6> and <-1, 3>.
How to determine the resulting point by applying translations
Translations are a kind of rigid transformation. A transformation is rigid if and only if Euclidean distances are conserved. By linear algebra, an image as a consequence of consecutive translations is described by the following formula:
[tex]P' (x,y) = P(x,y) + \left(\sum\limits_{i=1}^{n}x_{i}, \sum\limits_{i=1}^{n}y_{i}\right)[/tex] (1)
Where:
P(x, y) - Original pointP'(x, y) - Image[tex]\left(\sum\limits_{i=1}^{n}x_{i}, \sum\limits_{i=1}^{n}y_{i}\right)[/tex] - Net translation vectorNow we proceed to determine the image of the given point:
P'(x, y) = (-3, 4) + (7, -6) + (-1, 3)
P'(x, y) = (-3 + 7 - 1, 4 - 6 + 3)
P'(x, y) = (3, 1)
By applying concepts of linear algebra, the point P'(x, y) = (-3, 4) represents the translation of P(x, y) = (-3, 4) along the vectors <7, -6> and <-1, 3>.

(rounding) 0.46. whats the nearest tenth?
Answer:
0.5
Step-by-step explanation:
4 is in the tenths place and 6 is in the hundredths place
Since the digit in the hundredths place (6) is greater than or equal to 5, add 1 to the digit in the tenths place (4)
1 + 4 = 5, so the digit in the tenths place becomes 5
The digit in the hundredths place is dropped
0.46 rounded to the nearest tenth (one decimal place) = 0.5

rose is making trail mix bags for her hiking club. she will use 20 ounces of walnuts, 11.1 ounces of almonds, and 15.4 ounces of cashews. this amount makes 25 bags of trail mix. how many ounces are in each bag? (please have explanation and answer)
Answer: 1.86 oz. per bag
Step-by-step explanation: First we add the amount of ounces from each ingredient. 20+11.1+15.4 = 46.5
Then we divide by 25 to find out how many ounces per bag. 46.5/25=1.86
Answer:
2.15 ounces
Step-by-step explanation:
The total ounces of nuts in the bag is calculated as:
20 ounces of walnuts + 11.1 ounces of almonds + 24.8 ounces of cashews = 55.9 ounces.
From the question we are told that these amounts make 26 bags.
The number of ounces that are in each bag is calculated as:
26 bags = 55.9 ounces
1 bag = x ounces
Cross Multiply
26 bags × x ounces = 1 bag × 55.9 ounces
x ounces = 1 bag × 55.9 ounces/26 bags
x ounces = 2.15 ounces
Therefore, there are 1.94 ounces in each bag

Answer:
g(-3) = 23
Step-by-step explanation:
This question is telling us that x = -3. Knowing this, we can plug x into the equation and solve to find g(-3).
[tex]g(-3) = 3(-3)^{2} -4[/tex]
[tex]g(-3) =3(9)-4[/tex] Square -3 to get 9
[tex]g(-3) = 27-4[/tex] Multiply 9 by 3 to get 27
[tex]g(-3) = 23[/tex] Subtract 4 from 27 to get 23
Thus, g(-3) is equal to 23.

Identify the amount (a) and the growth factor (b) in each exponential function. Break B into (1+r) where the rate of growth. Give r as a percentage.
y=1.07 (1.96)x
a
b=
r(as a percentage)
Answer:
a = 1.07
b = 1.96
r = 96%
Step-by-step explanation:
In an exponential function, modeled by f(x) = a(b)ˣ, a is the initial value and b is the growth factor. If we apply this formula to the given function y = 1.07(1.96)ˣ, we can see that the initial value, a, is 1.07, and the growth factor, b, is 1.96.
Now, to break down b, 1.96, into a rate, you simply set it equal to the problem’s given (1 + r) equation to find the rate.
1.96 = 1 + r
So r = .96
Now, we just have to convert .96 into a percentage to get a growth rate of 96%.

Step-by-step explanation:
your a. is wrong.
so, we need to do both.
a.
you did not really read carefully. DE = 4x and not 4.
DE = 4x does not mean x = 4. absolutely not.
so, you cannot just use x=4 in the first triangle.
but you are right, AB and DE correlate between the 2 congruent triangles.
therefore
3x + 6 = 4x
6 = x
so, AB = 3x + 6 = 3×6 + 6 = 18 + 6 = 24 ft
b.
congruent means that the sides and the angles are the same between the 2 triangles.
so,
6y + 12 = 8y + 2
12 = 2y + 2
10 = 2y
y = 5
so, the angle EDF is
8y + 2 = 8×5 + 2 = 40 + 2 = 42°
