A rectangle or prism with a volume of three cubic units is filled with Cubes with side length of one for a few how many 1/4 unit does it take to fill the prism
Answer:
192 cubes.
Step-by-step explanation:
The volume of each cube = (side)³ = (1/4)³ = 1/64 units ³
Next is to find how many cubes are needed to fill the prism.
The number of cubes that will fill the prism :
Vol. of prism / Vol. of cube = 3 / [tex]\frac{1}{64}[/tex]
=192 cubes.
Therefore, it takes 192 cubes to fill the prism.
A farmer has 3000 feet of fencing to use on a new enclosure. The new enclosure will go up against existing fencing so one side does not need additional fencing. If the farmer wants to subdivide the enclosure to have 3 pens, what is the maximum total area the farmer can enclose?
Answer:
375000 ft^2
Step-by-step explanation:
From the statement that we have that it would be 1 time the length and 2 times the width because one side is not necessary and also we must take into account that it would be divided by 3 equal enclosures therefore we will use 1000 feet (3000/3) so Therefore, the perimeter would be equal to:
1000 = l + 2 * w
we solve for w:
l = 1000 - 2 * w
Also the area is equal to:
A = w * l
replacing:
A = w * (1000 - 2 * w)
A = 1000 * w - 2 * w ^ 2
We derive:
A '= 1000 - 4 * w
Let's equal 0:
1000 - 4 * w = 0
w = 1000/4
w = 250
replacing and we calculate l:
l = 1000 - 2 * 250
l = 500
A = 250 * 500
A = 15,000 ft ^ 2
Which means that for each subdivision the maximum area would be 125000 square feet and the total would be:
125000 * 3 = 375000 ft ^ 2
Somebody, please help me!! I will mark the brainiest
Answer:
65 = <JKL
Step-by-step explanation:
There are two expressions that represent the same thing.
The diagram shows that <JKL = 45 + x
The question states that JKL = 3x + 5
The two expressions must be equal since they represent the same thing.
3x + 5 = x + 45
Subtract 5 from both sides
3x + 5 - 5 = x + 45 - 5
3x = x + 40 Subtract x from both sides
3x - x = x - x + 40
2x = 40 Divide by 2
2x/2 = 40/2
x = 20
So x + 45 = 20 + 45 = 65
or
3x + 5 = 3*20 + 5 = 60 + 5 = 65

the base of the ladder to the wall.)
х
2x
The top of the ladder is
feet higher now.
Answer:
3.2 ft
Step-by-step explanation:
The initial distance from the base of the ladder to the wall is:
[tex]20^2=16^2+d^2\\d=12\ ft[/tex]
After moving the ladder, the distance from the base to the wall is 12 - 2x while the height of the ladder is 16 + x. The distance x is given by:
[tex]20^2 = (12-2x)^2+(16+x)^2\\400 = 144-48x+4x^2+256+32x+x^2\\5x^2-16x=0\\5x=16\\x=3.2\ ft[/tex]
Therefore, the top of the ladder is 3.2 ft higher now.

The measure of angle 1 is (10 x + 8) degrees and the measure of angle 3 is (12 x minus 10) degrees. what is the measure of angle 2 in degrees?
Answer:
82 degrees
Step-by-step explanation:
First set 10x+8 equal to 12x-10 to find that the variable is equal to 9. Then solve for 10(9)+8 which equals 98. Since angle 1 is supplementary to angle two and supplementary angles add up to 180 degrees, subtract 98 from 180 to find that your answer is 82 degrees.

Answer:
[tex]sin\theta_1 = \dfrac{\sqrt{217}}{19}[/tex]
Step-by-step explanation:
It is given that:
[tex]cos\theta_1 = -\dfrac{12}{19}[/tex]
And we have to find the value of [tex]sin\theta_1 = ?[/tex]
As per trigonometric identities, the relation between [tex]sin\theta\ and \ cos\theta[/tex] can represented as:
[tex]sin^2\theta + cos^2\theta = 1[/tex]
Putting [tex]\theta_1[/tex] in place of [tex]\theta[/tex] Because we are given
[tex]sin^2\theta_1 + cos^2\theta_1 = 1[/tex]
Putting value of cosine:
[tex]cos\theta_1 = -\dfrac{12}{19}[/tex]
[tex]sin^2\theta_1 + (\dfrac{12}{19})^2 = 1\\\Rightarrow sin^2\theta_1 + \dfrac{144}{361} = 1\\\Rightarrow sin^2\theta_1 = 1-\dfrac{144}{361}\\\Rightarrow sin^2\theta_1 = \dfrac{361-144}{361}\\\Rightarrow sin^2\theta_1 = \dfrac{217}{361}\\\Rightarrow sin\theta_1 = +\sqrt{\dfrac{217}{361}}, -\sqrt{\dfrac{217}{361}}\\\Rightarrow sin\theta_1 = +\dfrac{\sqrt{217}}{19}, -\dfrac{\sqrt{217}}{19}[/tex]
It is given that [tex]\theta_1[/tex] is in 2nd quadrant and value of sine is always positive in 2nd quadrant. So, the answer is.
[tex]\Rightarrow sin\theta_1 = \dfrac{\sqrt{217}}{19}[/tex]

-a+(-b) where a= 6.05 and b= 3.611
Answer:
-9.661
Step-by-step explanation:
In the given equation, a and b are negative. The values of a and b are given. If you insert the values into the given formula, the values become negative because of "-" in front of the a and b values.
-a + (-b) = -6.05 + (-3.611)
Because the second value is negative, the plus sign references to adding BOTH negative values together so it is just the same as saying:
-6.05 - 3.611
This gives you -9.661
Hope this helps!

Graph:
Answer: D . No association
Step-by-step explanation:
The relationship between two variable is called correlation.
When two variables has positive correlation ( When one variable increases by increasing the other) then it reprsesents Positive linear association .When two variables has negative correlation ( When one variable decreases by increasing the other) then it reprsesents Negative linear association .When two variables in which change in one variable does not correspond with constant change in the other variable, then it represents Nonlinear association.If two variables are not interdependent such that if one increasing then there is no proportional change in the other variable, then we say there is no correlation.Hence, the correct option is D. No association.
Hi There. (Choice D) Is The Right Answer.
Step-by-step explanation:
Which equation is equivalent to the following?
4x^2 + 4y^2 +16x – 24y = 34
Please answer it:(
Answer:
The correct answer is the third expression.
Step-by-step explanation:
We have the following equation:
[tex]4*x^2 + 4*y^2 + 16*x - 24*y = 34[/tex]
Let's organize it by variables, putting together the ones that have the same letter or no letter at all. We have:
[tex]4*x^2 + 16*x + 4*y^2 - 24*y = 34[/tex]
We can extract the common factor on the left side by dividing them by 4, we have:
[tex]4*(x^2 + 4*x) + 4*(y^2 - 6*y) = 34[/tex]
We need to complete the squares on the parenthesis without changing the value of the equation, to do that we will sum the proper values inside the parenthesis and those multiplied by four on the other side of the equation, we have:
[tex]4*(x^2 + 4*x + 4) + 4*(y^2 - 6*y + 9) = 34 + 16 + 36\\4*(x + 2)^2 + 4*(y - 3)^2 = 86[/tex]
The correct answer is the third expression.

Two hikers start a trip from a camp walking 15 miles due east. They turn north and walk 17 miles to a large pond. How far is the pond from base camp to the nearest tenth of a miles.
Answer:
22.7 miles
Step-by-step explanation:
The hikers start walking 15 miles due east and then they turn north and walk 17 miles to a large pond.
The shape of their journey can be represented as a right angled triangle, shown below.
To find the distance between the pond and the base camp, we need to find the hypotenuse of the triangle.
We can do this by using Pythagoras theorem:
[tex]hyp^2 = a^2 + b^2[/tex]
where a and b are the other two sides of the triangle. Therefore:
[tex]hyp^2 = 15^2 + 17^2\\\\hyp^2 = 514\\\\hyp = \sqrt{5`4} \\\\hyp = 22.7 miles[/tex]
The pond is 22.7 miles far from the base camp.
