Answer:
Cutting angle in radian θ = 3π / 2
Step-by-step explanation:
Given:
Diameter of pizza = 12 inch
He can eat = 84.8 inch²
Find:
Cutting angle in radian
Computation:
Radius of pizza = Diameter of pizza / 2
Radius of pizza = 12 / 2
Radius of pizza = 6 inch
Area of sector = [θ/360][πr²]
Area of sector = [θ/360][(π)(6)²]
84.8 = [θ/360][(π)(36)]
θ = 270°
θ = 270[π/180]
θ = 27π / 18
Cutting angle in radian θ = 3π / 2

RLLY HOPE THIS HELPS QUICK ANSWER TRYING Q.8
Answer:
k = -6
p = 1
Step-by-step explanation:
You can start by distributing:
8k - 6 = 6k + 18 + 6k
Next, you can combine like terms on the right side:
8k - 6 = 12k + 18
Now, you can subtract 8k from both sides to combine the terms with k:
-6 = 4k + 18
And subtract 18 from both sides to isolate the k-term:
-24 = 4k
Lastly, divide by 4 to get k.
k = -6
You can start by distributing -8:
-8 - 32p + 7p = -25 - 8p
Then combine the like terms in the left side:
-25p - 8 = -25 - 8p
Next, add 25p to both sides to combine the p-terms:
- 8 = -25 + 17p
And add 25 to isolate p:
17 = 17p
Divide by 17 to get the answer:
p = 1

Nine students can make a poster in 10 hours how many students join them so that they can all together make this poster in six hours
Answers
Answer:
there is not enough information
Answer:
If 9 students make the poster in 10 hours
Then it would take 1 student 90 hours to make 1 poster
Therefore you do 90 hours/6hours to get 15
So you'd need 15 students to make the poster in 6 hours
Which means 6 more students would need to join them

Is knowing the coordinates of the vertex of a parabola enough to determine the domain and range? a. No: we would have no information about the domain. c. Yes: if the vertex is at (m,n), then the domain is all reals and the range is y ≤ n. b. No: we would need to know if the vertex is a minimum or a maximum. d. Yes: if the vertex is at (m,n), then the domain is all reals and the range is y ≥ n.

A piece of land was worth $63,710.1 last year. This year, the cost of land has increased by 12%. How much is the land worth now? Round to the nearest whole number.
Answers
Answer:
$71,355
Step-by-step explanation:
The value of the land was 100% of the value of the land.
The value went up by 12%. 100% + 12% = 112%. Now the value of the land is 112% of the original value.
112% of $63,710.1 = 1.12 × $63,710.1 = $71,355

The restaurant manager wants to find how much they are spending for pies and cakes. Last week they payed 204$ for 12 pies and 8 cakes
Answers
Answer: See explanation
Step-by-step explanation:
Your question isn't complete and I couldn't get the exact question online but let's reframe it and solve it.
The restaurant manager wants to find how much they are spending for pies and cakes. Last week they payed 204$ for 12 pies and 8 cakes. This week, they paid $129 for 5 pies and 7 cakes.
Let's say the cost of pies is x
Let's say the cost of cake is y.
We'll then use the information given to make an equation which will be:
Last week they payed 204$ for 12 pies and 8 cakes. This will be:
12x + 8y = 204........ i
This week, they paid $129 or 5 pies and 7 cakes. This will be:
5x + 7y = 129 ........... ii
Therefore,
12x + 8y = 204........ i
5x + 7y = 129 .......... ii
Multiply equation i by 5
Multiply equation ii by 12
60x + 40y = 1020 ....... iii
60x + 84y = 1548 ........ iv
Subtract iii from iv.
44y = 528
y = 528/44
y = 12
The cost of cake is $12.
From equation i,
12x + 8y = 204
12x + 8(12) = 204
12x + 96 = 204
12x = 204 - 96
12x = 108
x = 108/12
x = 9
The cost of pies is $9.

question 4, plz help ( radius is 6.8)
Answers
Answer:
A) 145.3 cm^2
Step-by-step explanation:
The formula for the area of a circle is A = π r^2
So to find the area we would plug the radius of 6.8 into the formula
Area = π (6.8)^2
Area = (3.14) (6.8)^2
Area = 145.27
Area = 145.3

The formula to calculate arc length when central angle is in degrees =
Arc length = θ/360 × 2πr
r = radius = 1
θ = 81°
Hence:
Arc length in π =
= 81/360 × 2 × π × 1
= 162π/360
= 9π/20
Therefore, the arc length = 9π/20

What is the product of the complex numbers below?
(3-9i)(6-i)
Answers
Answer:
(9-57i)
Step-by-step explanation:
We need to find the product of the given complex number i.e.
(3-9i)(6-i)
It can be solved as follows :
(3-9i)(6-i) = 3(6) +3(-i) +(-9i)(6) + 9i(i)
= 18-3i-54i+9i²
We know that, i² = -1
So,
= 18-3i-54i+9(-1)
= 18-57i-9
= 9-57i
So, the product of the given complex number is (9-57i).
You start at (6, 7). You move right 3 units. Where do you end?
Answers
Answer:
(9, 7) is where you would end
Step-by-step explanation:
We know that;
x-value = 6
y-value = 7
We also know that by moving 3 units right u will add 3 to the x-value, therefore;
Final x-value = 6 + 3 = 9
Final y-value = 7 (there is no change)
Final coordinates: (9, 7)
