A.V=[tex]\frac{2}{3}\\[/tex](pi)(r²)
B.V=[tex]\frac{4}{3}\\[/tex](pi)(r³)
C.V=[tex]\frac{1}{3}\\[/tex](pi)(r³)
D.V=[tex]\frac{1}{3}\\[/tex](pi)(r²)
Answer:
B
Step-by-step explanation:
Assume the radius is r so the diameter is 2r
Height=2*d=2(2r)=4r since the diameter is twice the radius
Volume of cone=1/3 * pi*r^2*h
= 1/3 * pi*r^2*(4r)
=4/3 *pi *r^3
So B
Answer: B
h=2d
r=d/2
so h in terms of r is;
h=4r
V=pi*r^2*h/3
V=pi*r^2*4r/3=pi*4r^3/3=4/3(pi)(r^3)

y=7x+10 is the equation of a regression line in a scatter plot where x is the number of hours after a store opened and y is the total number of customers that have entered the store.
1. What does the slope of 6.9 mean in the correct context?
2. According to the regression equation, how many customers have entered the store after 5 hours? (Show all of your work)
Answer:
Step-by-step explanation:
Slope is an average. In this particular context, the slope of 6.9 (or 7) means that an average of 7 people entered the store every hour.
If x is the number of hours the store is open and we are told to find the number of customers that have entered the store after 5 hours, we fill in the equation as follows:
y = 7(5) + 10 and
y = 35 + 10 so
y = 45.
If you use 6.9 instead of 7:
y = 6.9(5) + 10 and
y = 34.5 + 10 so
y = 45.5
Since you can't count a half of a person, using 7 instead of 6.9 makes more sense.

The perimeter of a rectangle can be found using the equation P = 2L + 2W, where P is the perimeter, L is the length, and W is the width of the rectangle. Can the perimeter of the rectangle be 64 units when its width is 11 units and its length is 20 units?
A.No. If the length is 20 and the width is 11, the perimeter is P = 20 + 22 = 42, not 64.
B.No. If the length is 20 and the width is 11, the perimeter is P = 40 + 22 = 62, not 64.
C.Yes. If the perimeter is 64 units and the width is 11 units, then P + W is greater than D.40.
Yes. If the perimeter is 64 units and the width is 11 units, then P + W is less than 40.
Answer:
B: No
Step-by-step explanation:
P = 2L + 2W. If L = 20 and W = 11, then P = 2(20) + 2(11), or 62. This matches Answer B.
Answer: The correct option is
(B) No. If the length is 20 and the width is 11, the perimeter is P = 40 + 22 = 62, not 64.
Step-by-step explanation: Given that the perimeter of a rectangle can be found using the equation P = 2L + 2W, where P is the perimeter, L is the length, and W is the width of the rectangle.
We are to check whether the perimeter of the rectangle can be 64 units when its width is 11 units and its length is 20 units.
According to the given information, we have
Length, L = 20 units, width, W = 11 units and Perimeter, P = 64 units.
We have
[tex]P\\\\=2L+2W\\\\=2\times20+2\times11\\\\=40+22\\\\=62\neq64.[/tex]
Therefore, if length is 20 units and width is 11 units, then perimeter P = 40 + 22 = 62 units, not 64.
Thus, the answer is NO.
Thus, option (B) is CORRECT.

From the diagram diagram; [tex]\angle BAC=(x+6)\degree[/tex] and [tex]\angle ABD=2x\degree[/tex].
The opposite sides of a rhombus are parallel.The diagonals act as transversals. Therefore the co-interior angles will add up to 180 degrees.The pair of co-interior angles are [tex]\angle BAD[/tex] and [tex]\angle ABC[/tex].
Also the diagonals of a rhombus bisect corner angles.
This implies that:
[tex]\angle BAD=2(\angle BAC)\implies \angle BAD=2(x+6)\degree[/tex].
[tex]\angle ABC=2(\angle ABD)\implies \angle ABC=2(2x)\degree[/tex].
The co-interior angles are supplementary so we form the equation:
[tex]\angle BAD+\angle ABC=180\degree[/tex]
[tex]\implies 2(x+6)\degree+2(2x)\degree=180\degree[/tex]
Expand the parenthesis to get:
[tex]\implies 2x+12+4x=180\degree[/tex]
Group the similar terms:
[tex]\implies 2x+4x=180-12[/tex]
Simplify
[tex]\implies 6x=168[/tex]
Divide both sides by 6.
[tex]\implies \frac{6x}{6}=\frac{168}{6}[/tex]
[tex]\therefore x=28[/tex]

Given: △ABC is equilateral. The radius of each circle is r. Find: AB
Answer:
2r (1 + √3)
Step-by-step explanation:
Circle O₁ is tangent to AB. Let's call the point of intersection point D. If we draw a radius from the center O₁ to D, we know this forms a right angle.
△ABC is an equilateral triangle, so we know m∠A = 60°. If we draw a line from A to O₁, we know that bisects the angle, so m∠DAO₁ = 30°.
So △DAO₁ is a 30-60-90 triangle. We can find the length AD:
AD = r √3
Now on the other side, circle O₃ is tangent to AB. Let's call the point of intersection point E. We know it's the same triangle we found earlier, so:
EB = r √3
And finally, we can draw a rectangle connecting O₁, O₃, E, and D. The distance between O₁ and O₃ is 2r, so:
DE = 2r.
Therefore:
AB = r√3 + 2r + r√3
AB = 2r√3 + 2r
AB = 2r (1 + √3)
Here's a graph showing the steps. Hopefully this helps, let me know if you have questions!

Find the measures of two angles, one positive and one negative, that are coterminal with the given angle. 254°
Answer: 614° and -106°
Step-by-step explanation:
You have this angle in degrees:
254°
Then, in order to find the measure of a positive angle conterminal with the given angle in degrees (254°), you need to add 360 degrees. Therefore, the measure of the positive angle is:
[tex]254\°+360\°=614\°[/tex]
Now, to find the measure of a negative angle coterminal with the given angle in degrees (254°), you need to subtract 360 degrees. Therefore, this is:
[tex]254\°-360\°=-106\°[/tex]
A rancher wants to fence in an area of 1,000,000 square feet in a rectangular field and then divide it in half with a fence down the middle parallel to one side. Find a function that models the amount of fencing in terms of the width of the field, w, where w is the measurement of the fence down the middle of the field.
Answer:
f(w) = 3w + 2,000,000/w
Step-by-step explanation:
We know that the area of a rectangle is the product of its length and width:
A = LW
Filling in the given values lets us write an expression for the length of the field.
1,000,000 = Lw
L = 1,000,000/w
Since there are 3 fences of length w and two of length L, the total perimeter fence length is the sum ...
f(w) = 3w + 2(1,000,000)/w
Combining the constants, we have a function for the perimeter fence length in terms of the width of the field:
f(w) = 3w +2,000,000/w
Final answer:
The function that models the amount of fencing required for a 1,000,000 square foot rectangular field divided in half by a fence is F(w) = 3w + 2,000,000 / w. This represents the total length of fencing as a function of the width w.
Explanation:
The student is asking for a function that models the amount of fencing required for a rectangular field with an area of 1,000,000 square feet, which is then divided in half by a fence parallel to the width, w. To begin, let's denote the length of the field as L and the width as w. Since the area of the rectangle is given by L multiplied by w, and we know that the area is 1,000,000 square feet, we can express the length L in terms of w as L = 1,000,000 / w.
Now, total fencing required would be the perimeter of the rectangle plus the additional fence dividing it in half. The perimeter is calculated as 2w + 2L. Therefore, the total fencing F in feet would be F(w) = 2w + 2L + w.
Substituting L with 1,000,000 / w, the function becomes F(w) = 2w + 2(1,000,000 / w) + w = 3w + 2,000,000 / w. This function represents the total length of fencing needed in terms of the width w of the field.

The volume of a pyramid is one-third of the volume of a prism with the same base area and height, yielding the formula V = (1/3)Bh for the volume of a pyramid.
Explanation:When comparing the volume of a prism and a pyramid with the same base and height, the volume of a pyramid is one-third of the volume of the prism. Therefore, the formula for the volume of a prism is V = Bh, where B is the base area and h is the height. Applying this to the pyramid, the pyramid's volume becomes V = (1/3)Bh. This formula tells us that the volume of a pyramid is equal to one-third of the product of the area of its base and its height.

Step-by-step explanation:
a: 70°
Reason: a is supplementary to the angle that measures 110°, so 180° - 110° = 70°
b: 55°
Reason: b is vertical to the angle between 100° and 25° (which add up to 125°) and since all of those angles added together have to equal 180°, then the unidentified angle between 100° and 25° = 55°. b is vertical to that angle so b = 55°
c: 25°
Reason: c is vertical the angle measuring 25° so c = 25° also.

131°
151
Answer:
29°
Step-by-step explanation:
Angles 1 and 8 are alternate exterior angles where a transversal crosses parallel lines, so are congruent.
m∠1 = m∠8
3x+25 = 4x-17
42 = m . . . . . . . . add 17-3x
Then the measure of ∠1 is 3·42 +25 = 151 (degrees), and the measure of its supplement, ∠2 is ...
m∠2 = 180° -151° = 29°
Lisa has $150 at most to spend on clothes. She wants to buy a pair of jeans for $58 and will spend the rest on t-shirts that cost $14 each. (5 points each) 2. Create an inequality to represent the number of t-shirts that Lisa can purchase. You can create a visual model in a paint program if that helps. Make sure you explain what the variable represents in your inequality
The inequality used in this situation will be 14x + 58 < 150.
What is inequality?The word inequality means a mathematical expression in which the sides are not equal to each other.
Let the no. of T-shirts Lisa can buy be = X
Cost of each T-shirt = $14
No. of jeans she bought = 1
Cost of jeans = $58
Total money she has = $150
Hence, the inequality will be 14X + 58 < 150.

Lisa can spend a maximum of $92 on T-shirts after buying jeans, and with each T-shirt costing $14, she can buy up to 6 T-shirts as represented by the inequality 14t <= $92, where t is the number of T-shirts.
Explanation:To create an inequality representing the number of T-shirts Lisa can purchase, let's define the variable t to represent the number of T-shirts. Lisa has $150 to spend, and she wants to buy a pair of jeans for $58, leaving $150 - $58 = $92 for T-shirts. Each T-shirt costs $14, so if Lisa buys t T-shirts, the cost for the T-shirts is 14t. The inequality to represent the maximum number of T-shirts Lisa can buy is 14t ≤ $92.
Now, to solve for t, we divide both sides of the inequality by 14: t ≤ $92 / $14, which simplifies to t ≤ 6.57. Since Lisa cannot buy a fraction of a T-shirt, the maximum number of T-shirts she can buy is 6.
