Roy Made A Pizza That Is 12 Inches In Diameter. He Knows He Can Eat About 84.8 In, At What Angle Should (2024)

Mathematics High School

Answers

Answer 1

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

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

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.

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 =

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)
