the sum of 12+12
12+12 is an even
number?
Answer:
An even number is a number that can be divided into two equal halves.
Also even numbers end in one of these digits: 0, 2, 4, 6, or 8
12 + 12 + 12 + 12 = 48
48 with the digit 8
48 divided in half gives two equal halves:
48/2 = 24
The number 24 can be added twice to check that the answer is correct:
24 + 24 = 48
So to summarize:
The sum of 12 + 12 + 12 + 12 is an even number because it can be equally divided in two halves and it ends in the digit 8.

Find the volume of a pyramid with a square base, where the perimeter of the base is
15.8 ft and the height of the pyramid is 20.4 ft. Round your answer to the nearest
tenth of a cubic foot.
(It’s on deltamath)
The volume of the given pyramid is 106.1 cubic foot.
To Find the Volume of a pyramid with a square base
Given:
The perimeter of the base is 15.8 feet
The base of the pyramid is square given of side say L .
Thus, from the formula of perimeter of square,
⇒ 4*L = 15.8 feet
∴ L = 3.95 feet
Now the base area of the pyramid is [tex]L^{2}[/tex] as it is a square .
∴ Base area = 3.95*3.95 square feet
= 15.6025 square foot
Now, formula for volume of the pyramid
= 1/3 * base area * height
⇒ Volume = 1/3 * 15.6025 * 20.4 cubic foot
∴ Volume = 106.097 cubic foot
Thus volume of the given pyramid is 106.1 cubic foot rounded off to nearest tenth.

Complete Question:
The scatter plot shows the number of oranges picked, in hundreds, in relation to the number of lemons harvested, in hundreds, by several farmers. According to the plot, which value is the best estimate of the correlation coefficient of the data?
A.-0.2
B. -0.9
C. 0.9
D. 0.2
*See attachment for the scatter plot
Answer:
C. 0.9
Step-by-step explanation:
If we take a good look at the scatter plot in the attachment showing numbers if oranges picked in relation to number of lemons harvested, we can infer that there's a strong positive correlation between both variables.
Thus, both variables are moving in the same direction. As one variable increases, the other variable increases. Also, the data points represented on the plot seem clustered close to the line rather than farther away.
This will suggest a positive correlation coefficient that is closer to 1.
From the options given above, the best estimate of the correlation coefficient would be 0.9.
The answer is C. 0.9

make x the subject of the formula a=b(1-x)
Answer:
x = -(a - b)/b
Step-by-step explanation:
Solve for x:
a = b (1 - x)
a = b (1 - x) is equivalent to b (1 - x) = a:
b (1 - x) = a
Divide both sides by b:
1 - x = a/b
Subtract 1 from both sides:
-x = (a - b)/b
Multiply both sides by -1:
Answer: x = -(a - b)/b
the tires of a tractor are 5.25 feet tall. what measure would help to find how many feet the tractor will travel in 1 rotation
and how many feet would it travel
Answer:
16.485 feet
Step-by-step explanation:
Given that tire is 5.25 feet tall
any circular shape is as tall as its diameter.
we can say that diameter of tire is 5.25 feet.
in one rotation tire will start from one point of tire and reach it again.
it is like on a circle moving from on one point and then reaching to same point.
and we know that distance covered on moving on the point of circle is equal to circumference.
Thus, measure of circumference would help to find how many feet the tractor will travel in 1 rotation.
circumference of circle is given by [tex]\pi D[/tex]
where D is the diameter of circle.
we will us 3.14 as value of [tex]\pi[/tex]
thus, circumference of circle is[tex]\pi * 5.25 = 3.14*5.25 = 16.485[/tex]
Hence, tractor would travel 16.485 feet in one rotation.
At my apartment I have a closet with 250 ft3 worth of space. If each of my spherical cannonballs have a radius of .75 feet, how many can I fit in my closet?
Answer:
141
Step-by-step explanation:
We need to first find the volume of the cannonballs and then, divide the volume of the closet by the volume of the cannonballs.
The radius of the spherical cannonball is 0.75 feet.
The volume of a sphere is:
[tex]V = \frac{4}{3} \pi r^3[/tex]
where r = radius
Therefore, the volume of the cannonballs is:
[tex]V = \frac{4}{3} * \pi * 0.75^3\\\\V = 1.77 ft^3[/tex]
Therefore, the number of cannonballs that can fit the closet is:
250 / 1.77 = 141.24
Since the number is a maximum and it must be a whole number, the number of cannonballs that can fit the closet is 141.

solve for p
Answer:
p = - 5i or p = 5i
Step-by-step explanation:
Noting [tex]\sqrt{-1}[/tex] = i
Given
p² = - 25 ( take the square root of both sides )
p = ± [tex]\sqrt{-25}[/tex] = ± [tex]\sqrt{25(-1)}[/tex] = ± 5i
Thus
p = - 5i or p = 5i
Because p squared is equal to -25, the square root of -25 is equal to p.
Because of this, finding the square root of -25 will give us our answer.
[tex]\sqrt{-25}[/tex] = 5i
Therefore, p = 5i or p = [tex]\sqrt{-25}[/tex].

a) Find the modal class interval.
f(x)=4x+1 and g(x)=x^2-5 find f+g (x)
Answer & Step-by-step explanation:
When we see (f + g)(x), it means that we are adding together f(x) and g(x).
f(x) = 4x + 1
g(x) = x² - 5
(f + g)(x) = (4x + 1) + (x² - 5)
Combine like terms and make sure x² is in the front of the expression so you are following the rules of exponents when in standard form.
(f + g)(x) = x² + 4x - 4
So, (f + g)(x) equals x² + 4x - 4

Answer:
x° = ∠OBR = ∠ABC (base angles of a cyclic isosceles trapezoid)
Step-by-step explanation:
APRB form a cyclic trapezoid
∠APO = x° (Base angle of an isosceles triangle)
∠OPR = ∠ORP (Base angle of an isosceles triangle)
∠ORB = ∠OBR (Base angle of an isosceles triangle)
∠APO + ∠OPR + ∠OBR = 180° (Sum of opposite angles in a cyclic quadrilateral)
Similarly;
∠ORB + ∠ORP + x° = 180°
Since ∠APO = x° ∠ORB = ∠OBR and ∠OPR = ∠ORP we put
We also have;
∠OPR = ∠AOP = ∠BOR (Alternate interior angles of parallel lines)
Hence 2·x° + ∠AOP = 180° (Sum of angles in a triangle) = 2·∠OBR + ∠BOR
Therefore, 2·x° = 2·∠OBR, x° = ∠OBR = ∠ABC.

The length of a rectangular swimming pool is p m and its width is q m. It is given that the length of the swimming pool is twice its width. If the perimeter of the swimming pool is 150 m, find the values of p and q.
(**please use the simultaneous linear equations in two variables to solve this question)
**if you have answer this question I will choose you to be the brainlest answer**
Answer: q = 25 m, p = 50 m
Step-by-step explanation:
p is the length, and q is the width.Since the length is twice as long as the width, we can come up with the equation: p = 2qSince the perimeter is 150, we can also come up with this formula since the perimeter is all sides added together: 2p + 2q = 150Since we have two equations, we can just plug them into each other. First, let's substitute the 2q in the second equation with p that is defined in the first equation: 2p + p = 150If we simplify that, we get: 3p = 150Now we know that p = 50 m.Now, if you plug in 50 into the first equation you get: 50 = 2q.Next, just simplify, and you know that q = 25 m.Therefore, p = 50 m, q = 25 m.What is MZM

Answer: m√M = 98°
Step-by-step explanation:
x + x + 6 + 3x - 16 = 180
5x - 10 = 180
5x = 180 + 10
x = 190 / 5 = 38
m√M = 3x - 16
= 3(38) - 16
= 98°
Answer:
m<M = 98 deg
Step-by-step explanation:
Theorem
The sum of the measures of the angles of a triangle is 180 degrees.
Now we set the sum of the measures of the angles equal to 180 and solve for x.
3x - 16 + x + 6 + x = 180
5x - 10 = 180
5x = 190
x = 38
Now that we know x, we substitute x with 38 in the expression for the measure of angle M.
m<M = 3x - 16
m<M = 3(38) - 16
m<M = 114 - 16
m<M = 98

Xavier can work no more than 40 hours in a week. He has already worked 24 hours this week. What is the maximum number of 8-hour days Xavier can work for the rest of the week?
Answer:
He can work a maximum of 2 8-hour days for the remainder of the week
Step-by-step explanation:
Firstly, from the question, we are made to know that the maximum work hours is 40 hours.
Now, we know that he has already worked 24 hours this week, the number of hours remains to work will be 40-24 = 16 hours
Now, given that his working hour is 8-hours per day, we want to know the number of days he has to work for the remainder of the week
Mathematically, that would be 16 hours divided by 8-hours days
