Emilio is pickling tomatillos with his grandfather. The tomatillos are approximately
spheres with a diameter of 6 cm. The pickling jar they are using has a diameter of
8 cm and a height of 21 cm. The jar can hold 3 tomatillos.
The jar can hold a total of three tomatoes at a time.
What is volume?
Volume is the amount of space occupied by a three dimensional shape or object.
The tomatoes is spherical with a diameter of 6 cm (radius = 6/2 = 3cm), hence:
Volume of tomatoes = (4/3) * π * radius³ = (4/3) * π * 4³ = 268 cm³
The jar is cylinder with diameter of 8 cm (radius = 8/2 = 4) and a height of 21 cm, hence:
Volume of jar = π * radius² * height = π * 4² * 21 = 1055.6 cm³
Amount of tomatoes that can be contained in jar = 1055.6 cm³ / 268 cm³ = 3.9
The jar can hold a total of three tomatoes at a time.

There are 13 boys and 10 girls in the classroom. What is the ratio of boys to girls?
A 10 to 13
B 13 to 10
C 23 to 13
D 23 to 10
Answer:
13 to 10
Step-by-step explanation:
13 boys, 10 girls
13:10
The ratio of boys to girls in the classroom is 13:10
hence option B is correct
According too the given situation
The number of boys in the classroom = 13
The number of girls in the classroom = 10
Ratio is a quantitative relationship between two numbers showing a comparable form of magnitudes of both the numbers/quantities.
Let "a" and "b" be two numbers then the Ratio of "a" and "b" is shown as formulated in equation (1)
[tex]\rm r = a:b ........(1)[/tex]
The ratio of two numbers can be found out in simplest form by dividing these two numbers such that the division results in positive natural numbers for both the quantities.
So we can conclude that the ratio of boys to girls in the classroom are
[tex]\rm \dfrac{Boys }{Girls } =\dfrac{13}{10} \\\\Boys : Girls = 13:10 \\[/tex]
So we can conclude that the ratio of boys to girls in the classroom is 13:10
hence option B is correct

H2+2h-120
The first 2 (one after H) is square
Answer:
(h + 12)(h - 10)
Step-by-step explanation:
Assuming you require to factor the expression
Given
h² + 2h - 120
Consider the factors of the constant term (- 120) which sum to give the coefficient of the h- term (+ 2)
The factors are + 12 and - 10 , since
12 × - 10 = - 120 and 12 - 10 = + 2 , thus
h² + 2h - 120 = (h + 12)(h - 10) ← in factored form

Identify 3 solutions to the system of inequalities .. hurry up please
Answer:
The solutions to this system of inequalities are included in this inequality:
5/3x - 4 < y < 1/4x - 4
Here are an example of 3 solutions:
(-1,-5), (-2,-6), (-4,-8)
In rectangle EFGH, EH I FG and EH crosses the y-axis at (0.-2). If the equation of the line containing FG is x + 3y = 12, write the equation of the line containing EH in slope- intercept form. Show your work to justify your answer.
Answer:
y = (-1/3)x - 2
Step-by-step explanation:
First we should put the equation for FG into slope intercept form, which is y = mx + b. For this step, just solve for the y in the equation, which should be y = (-1/3)x + 4.
Next, since we know that FG and EH are parallel, their slopes must also be the same. We also know the (0, -2) is a point on EH, and also happens to be the y-intercept. Therefore, we can plug it back into the slope intercept equation and get y = (-1/3)x - 2, since the m is the same and the -2 is just the y-intercept given in the problem.

The formula for distance traveled d is d=rt, where r is the average speed of the object and t is time traveled. if an object travels 30 meters in 20 seconds, what is its speed?
Answer:
1.5 meters per second.
Step-by-step explanation:
Distance formula:
d = rt
where d = distance, r = average speed and t = time traveled.
They told us that an object travels 30 meters in 20 seconds.
So we can say d = 30 and t = 20
if you put these values back into the distance formula you get:
d = rt
30 = r times 20
30 = 20 r
So now we want to find what "r" (average speed) is.
Divide both sides by 20.
20 r = 30
r = = 1.5 meters per second.

If n = 440 and ^p(p-hat) = 0.1, construct a 99% confidence interval. Give your answers to three decimals. Please list formulas in excel used if possible
___ < p < ___
====================================================
Explanation:
The spreadsheet is shown below.
In cell B6, the formula used is the NORMINV function to get the z critical value. The name is the result of putting the words "NORM" and "INV" together, which refers to the inverse normal.
It's used to find the value of k in P(-k < Z < k) = 0.99, which in this case is roughly k = 2.576 so the z critical value is roughly z = 2.576
What you type in specifically is [tex]=\text{NORMINV}( (1-0.99)/2, 0, 1)[/tex]
The (1-0.99)/2 portion ensures that we get the alpha/2 value which in this case is 0.005
The 0,1 at the end refers to the mean and standard deviation respectively of the standard normal Z distribution.
The output of that NORMINV function is then made positive and then you'd round to 3 decimal places.
So that's how we can get excel to display z = 2.576
----------
The margin of error E formula is
E = z*sqrt(phat*(1-phat)/n)
which doesn't need an excel function to get the job done, though of course excel can handle it just fine. You'd type in the formula as shown, but be sure to reference the correct cells.
Once E is calculated, we compute the following
L = phat - EU = phat + Ewhich are the lower (L) and upper (U) bounds of the confidence interval.
The results are L = 0.063 and U = 0.137
That confidence interval can be written in the form (0.063, 0.137) which is equivalent to saying 0.063 < p < 0.137
In triangle ABC, M is the midpoint of AB. Let D be the point on BC such that AD bisects angle BAC, and let the perpendicular bisector of AB intersect AD at E. If AB = 44, AC = 30, and ME = 10, then find the area of triangle ACE.
Help Please!
The area of Triangle ACE from the given diagram is; 150 sq.units
What is the area of the triangle?We are given;
AB = 44
AC = 30
ME = 10
Now, to find the area of triangle ACE, we need to know the length KE where K is the midpoint of AC.
Now, since AD bisects angle BAC. This means that ∠KEA = ∠MEA.
By ASA Congruence Postulate, we can say that; ΔAEK ≅ AEM
Thus, we can say that KE = ME = 10
Formula for area of triangle is;
A = ¹/₂ * base * height
where;
base = AC = 30
Height = KE = 10
Thus;
A = ¹/₂ * 30 * 10
A = 150

How many theorems are there for circles? And what are they?
Find the value of x that will make A||B
Answer:
x=12
Step-by-step explanation:
Because the angles labeled 5x and 4x+12 ate opposite exterior angles, they are congruent. This means that we can set up the following equation:
5x=4x+12
Subtracting 4x from both sides, we have:
X=12
Answer:
x = 12
Step-by-step explanation:
When two parallel lines are intersected by a transversal, the alternate exterior angles are congruent.
5x = 4x + 12
Subtract 4x from both sides,
5x - 4x = 4x - 4x + 12
x = 12
