Answer:
576 cm³
Step-by-step explanation:
Radius = Diameter ÷ 2
8 ÷ 2 = 4
4² = 16
Using 3 for pi, 16 x 3 = 48
48 x 12 = 576
therefore each gift has a volume of 576 cm ³
The volume of tye cylinder is therefore 576cm³
The volume of a cylinderThe formula for calculating the volume of the cylinder
V = πr²h
Given the following parameters
r = 4cm
h = 12cm
How to calculate the volume of the cylinder?The volume of the cylinder will be:
V = 3(4)²(12)
V = 3(16)(12)
V = 576cm³
Hence the volume of a cylinder is 576cm³

Danielle poured 3/4 gallon of water from a 7/8 gallon bucket.How much water is left in the bucket?
Answer:
1/8
Step-by-step explanation:
3/4 = 6/8 after you multiply top and bottom by 2
Subtract 3/4 from 7/8 and we get
7/8 - 3/4 = 7/8 - 6/8 = (7-6)/8 = 1/8
There is 1/8 of a gallon left

A passenger jet can fly 1290 miles in three hours with a tail wind but only 1230 miles in three hours into a Herman. Find the speed of the jet in still air and the speed of the wind
The speed of the plane is 420 miles per hour and the speed of the wind is 10 miles per hour.
Answer:
I only know English, so that's perfect :P
Step-by-step explanation:
I'm going to guess... that "Herman" is really "headwind" and that this jet is flying into ( headwind) and with ( tailwind) the same wind... so the same velocity wind ( note I used the physics term velocity for the speed of the wind b/c the wind also has to have a direction... and we are saying it's direction and it's speed are constant)
so take the difference of the two distances... 1290 - 1230 = 60
we now know... that the difference in distance traveled is 60 miles, so 1/2 of that is what's gained or lost , by a tailwind or a headwind, so 30 miles is gained or last flying into the wind or with the wind.
also this is in 3 hours , how convenient, 30 / 3 = 10
the wind is 10 MPH
there fore.... the jet could fly 1260 miles in 3 hours with out any wind or
d = rt where d= distance , r= rate ( think speed) and t = time ( of course [ofc] )
1260 = r * 3 hours
420 = r
the jets speed is 420 MPH

An occupational safety officer for a large company is conducting a study to investigate back problems in office workers who use a computer for most of the workday. The study will
investigate the difference in back problems for workers who stand and workers who sit. A group of 68 volunteers have agreed to participate in the nine-month study. Half the group
is randomly assigned to work while standing, and the other half is assigned to work while sitting. At the end of the study, the mean number of back problems between the two
groups will be calculated. The officer will use the results to estimate the difference in the mean number of back problems between those who work while standing and those who
work while sitting
Which of the following is an appropriate inference procedure for the study?
Answer:
Answer is E
Step-by-step explanation:
did the test, also person who answered before was wrong
Considering the situation described, the appropriate test is given by:
E) A two sample t-interval for difference between population means.
When to use the t-distribution and the z-distribution?If we have the standard deviation for the sample, the t-distribution is used.If we have the standard deviation for the population, the z-distribution is used.In this problem, we will have the data from the sample, hence it is a t-test. We will compare the population means of the two groups, hence a two-sample t-interval is used, and option E is correct.

At a part-time summer job, Luiz earn $10.10 per hour. Which equation can be used to find how many
hours he must work to earn $232.30?
A. 232.30x - 10.10
B. 10.10x - 232.30
C. 10.10+ x - 232.30
D. x - 10.10+232.30
Answer:
I would say it is B
Step-by-step explanation:
Because to find the value of x, you would need to divided 232.30 by 10.10, you have to use the opposite for algebra so the opposite is multiplication.
one integer is 6 more than another. their product is 216. find the integers.
Answer:
-18 and -12
Or, 18 and 12
Step-by-step explanation:
Let the integers be 'a' & 'a + 6'.
Their product = 216
=> a x (a + 6) = 216
=> a² + 6a = 216
=> a² + 6a - 216 = 0
=> a² + (18 - 12)a - 216 = 0
=> a² + 18a - 12a - 216 = 0
=> a(a + 18) - 12(a + 18) = 0
=> (a + 18)(a - 12) = 0
=> a = - 18 or a = 12
Integers are: -18 and -18+6 = -12
Or, 12 and 12 + 6 = 18

Some steps are shown in converting the following conic inequality from general form to standard form. Complete the conversion and identify the shape, key feature, and which ordered pair is part of the solution set.
Answer:
hyperbola with a solid line boundary
(4, -2)
(0, -4)
Step-by-step explanation:
Took one for the team Edge 2021
The shape of the given equation is hyperbola with solid line boundary, key feature i.e. the center is at (4, -2), and ordered pair is (0, -4) and the standard form will be [tex]\frac{(x-4)^2}{9} -\frac{(y+2)^2}{4} \leq1[/tex] .
What is conic section ?Conic section is a curve obtained by the intersection of the surface of a cone with a plane.
we have,
[tex]4x^2-32x-9y^2-36y-8\leq 0[/tex]
And,
The general form of a Conic Section is,
[tex]Ax^2+Bxy+Cy^2+Dx+Ey+F=0[/tex]
And,
The Standard form of a is,
[tex]\frac{(x-h)^2}{a^2} +\frac{(y-k)^2}{b^2} =1[/tex]
So,
Now,
[tex]4x^2-32x-9y^2-36y-8\leq 0[/tex]
Then,
[tex]4x^2-32x-9y^2-36y\leq8[/tex]
Now, taking common,
[tex]4(x^2-8x)-9(y^2+4y)\leq8[/tex]
Now,
Adding 64 and subtracting 36 to both sides ,
We get,
[tex]4(x^2-8x+16)-9(y^2+4y+4)\leq8+64-36[/tex]
Now,
factor the perfect square,
i.e.
[tex]x^2-8x+16=(x-4)^2[/tex]
Now,
[tex]y^2+4y+4=(y+2)^2[/tex]
Now,
[tex]4(x-4)^2-9(y+2)^2\leq36[/tex]
Now,
Divide both sides by 36,
i.e.
[tex]\frac{4(x-4)^2}{36} -\frac{9(y+2)^2}{36} \leq\frac{36}{36}[/tex]
We get,
[tex]\frac{(x-4)^2}{9} -\frac{(y+2)^2}{4} \leq1[/tex]
So, this is the standard form of the given cubic inequality.
Hence, we can say that the shape of the given equation is hyperbola with solid line boundary, key feature i.e. the center is at (4, -2), and ordered pair is (0, -4) and the standard form will be [tex]\frac{(x-4)^2}{9} -\frac{(y+2)^2}{4} \leq1[/tex] .
