The radius of a. circular garden is 15 feet. About how much fencing will be needed to enclose the garden?
Answer:
94.2 ft of fencing
Step-by-step explanation:
To answer this, find the circumference, C, of the garden, using the circumference formula C = 2(pi)r.
Here, with r = 15 ft, we get C = 2(3.14)(15 ft) = 94.2 ft of fencing will enclose this garden.

Step-by-step explanation:
A standard number cube, labeled numbers 1-6 on each side, is rolled three times. Mary says the chance of rolling a 2 all three times is 1/8. But John disagrees and says the probability for rolling a 2 all three times is 1/216. Who calculated the correct probability or rolling a 2 the three times the n number cube is rolled? Show work to justify your reasoning.
Answer: john answer it correctly

Answer:
9) 379.94 mm2
10)19.625 ft2
Step-by-step explanation:
a=(pi)r2
a=3.14(11 mm2)
a=3.14(121 mm2)
a=3.14*121 mm2
a=379.94 mm2
a=(pi)r2
a=3.14(2.5 ft2)
a=3.14(6.25 ft2)
a=3.14*6.25ft2
a=19.625 ft2
Answer:
(I don't know where to round the numbers to, so I'll just put the full areas)
The answer to 9. is: 380.132711 mm², and the answer to 10. is: 19.6349541 ft².
Step-by-step explanation:
The formula for the area of a circle is A = πr². (A = area, π = pi, r = radius.) When you substitute the variables in the formula for the values of question #9, you get A = π(11)². (It's 11 because the radius is half of the diameter, which in this case is 22 mm.) And when you substitute the variables for the values of question #10, you get A = π(2.5)². And from there, you just finish the equations. Hope this helps :)

What is the first error Zoe made in her proof?
a. Zoe used an invalid reason to justify the congruence of a pair of sides or angles
b. Zoe only established some of the necessary conditions for a congruence criterion.
c. Zoe established all necessary conditions, but then used an inappropriate congruence criterion.
d. Zoe used a criterion that does not guarantee congruence
iui
Answer:
a
Step-by-step explanation:
To prove congruence
1 ∠ A ≅ ∠ C → given
2 ∠ DEA ≅ ∠ BEC → vertically opposite angles
3. AE ≅ EC → given
We then have 2 angles and the included side ( side between the 2 angles )
congruent in both triangles, thus Δ AED ≅ Δ CEB ( ASA postulate )
Zoes' error was in assuming ∠ DEA ≅ ∠ BEC was given
Zoe used an invalid reason to justify the congruence of a pair of sides or angles.
Option a is correct.
From given diagram it is observed that,
Line segment AD and CB are parallel and AC is transversal line. So that alternate angles A and C are equal.
[tex]\angle A=\angle C[/tex]
When two lines intersect at any point then vertically opposite angles are equal.
So that, [tex]\angle DEA=\angle BEC[/tex]
Given that , [tex]AE=EC[/tex]
The Angle-Side-Angle Postulate (ASA) states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.
Hence, both triangles are congruent to each other.

A company estimates that 0.1% of their products will fail after the original warranty period but within 2 years of the purchase, with a replacement cost of $350. If they offer a 2 year extended warranty for $28, what is the company's expected value of each warranty sold?
Answer:
The expected gain per warranty is $27.65, crazy stuff
Step-by-step explanation:
If the estimate is right, there is a 0.1% probability for each extended warranty that the company has to shell out $350 (we disregard the situation where the replacement fails too, because there is no info that lets us deal with that).
This brings us to cost for the company equal to 0.1%*$350 per warranty sold.
0.1%*$350 = 0.001*$350 = $0.35
And the company gets $28 for each warranty sold, hence they earn
$28 - $0.35 = $27.65
on average.

Can the theoretical probability of the cup landing on its side be calculated based on the information given?
Answer:
If given enough information yes
Step-by-step explanation:
If you were given the weight and the distibution of the weight and the elasticity of the cup, as well as the trajectory of the cup and the force it was thrown at, and the proportions of the cup, its shape, where it's landing, etc. You could give a definitive probability. For example, If there is more weight at the bottom of the cup it might be less probable to land on it's side

Answer:
0.54 or 54%
Step-by-step explanation:
P( 1st but not second) = P(1st) - P(1st and Second) = 0.4 - 0.28 = 0.12 = 12%
P( 2nd but not first) = P(2nd) - P(1st and Second) = 0.7 - 0.28 = 0.42 = 42%
Probability of 1 of them (exactly one) = P( 1st but not second) + P( 2nd but not first) = 0.12 (12%) + 0.42 (42%) = 0.54 or also 54%.

Under her cell phone plan, Savannah pays a flat cost of $37.50 per month and $3 per
gigabyte. She wants to keep her bill at $51.90 per month. Which equation or tape
diagram could be used to represent the context if g represents the number of
gigabytes of data Savannah can use while staying within her budget?
Answer:
(51.90 - 37.50) / 3 = G
14.40 / 3 = G
4.8 = G
Savannah will be able to use 4 gigabytes to stay within her budget.
Step-by-step explanation:
Given that under her cell phone plan, Savannah pays a flat cost of $ 37.50 per month and $ 3 per gigabyte, and she wants to keep her bill at $ 51.90 per month, to determine which equation or tape diagram could be used to represent the context if g represents the number of gigabytes of data Savannah can use while staying within her budget, the following calculation should be performed:
(51.90 - 37.50) / 3 = G
14.40 / 3 = G
4.8 = G
Therefore, Savannah will be able to use 4 gigabytes to stay within her budget.
find the area of the shaded region to the nearest tenth
Answer:
Area of shaded region = 13.07 unit² (Approx.)
Step-by-step explanation:
Given:
Given shaded region is a segment
Radius of circle = 12
Given angle = 60°
Find:
Area of shaded region
Computation:
Area of shaded region = Area of segment
Area of segment = (θ/360)(π)(r²) - (1/2)(sinθ)(r²)
Area of segment = (60/360)(22/7)(12²) - (1/2)(sin60)(12²)
Area of segment = (0.1667)(3.14)(144) - (0.5)(0.866)(144)
Area of segment = (75.42) - (62.35)
Area of segment = 13.07 unit²
Area of shaded region = 13.07 unit² (Approx.)
