Answer:
(6)=120°
(10)=72°
(20)=36°
Step-by-step explanation:
(n-2)×180°
(6-2)×180°=720°
6÷720°=120°
10÷720°=72°
20÷720°=36°
Consider two circular swimming pools. Pool A has a radius of 24 feet, and Pool B has a diameter of 14.82 meters. Complete the description for which pool has a greater circumference. Round to the nearest hundredth for each circumference. 1 foot ≈ 0.305 meters The diameter of Pool A is meters. So, the diameter of Pool (select) is greater, and the circumference is (select) by meters.
Answer:
The diameter of Pool A is 14.64 meters. So, the diameter of Pool B is greater, and the circumference is greater by 0.56 meters.
Step-by-step explanation:
Identify the diameter of Pool A.
d = 2r
d = 2(24) Substitute 24 for r.
d = 48 ft
Convert from feet to meters. Use the ratio of 1 foot to 0.305 meters. Round to the nearest hundredth.
48 × 0.305 = 14.64
The diameter of Pool A is about 14.64 meters.
Use the formula to find the circumference of Pool A.
C = πd
C = π(14.64) Substitute 14.64 for d.
C ≈ 3.14(14.64) Substitute 3.14 for π.
C ≈ 45.97 Multiply.
The circumference of Pool A is about 45.97 feet.
Identify the diameter of Pool B.
d = 14.82 m
The diameter of Pool B is 14.82 meters.
Use the formula to find the circumference of Pool B.
C = πd
C = π(14.82) Substitute 14.82 for d.
C ≈ 3.14(14.82) Substitute 3.14 for π.
C ≈ 46.53 Multiply.
The circumference of Pool B is about 46.53 feet.
The circumference of Pool B is greater than the circumference of Pool A.
Find how much greater the circumference of Pool B is compared to the circumference of Pool A.
46.53 − 45.97 = 0.56
The circumference of Pool B is greater than the circumference of Pool A by about 0.56 meters.
30 POINTS IF ANSWERED QUICKLY!!! The contractor in charge of the roofing project is trying to make the job the most cost effective for the homeowners. In order to cut back on the cost of supplies, he decides that a ceiling in the garage is not necessary. In other words, there will not be a barrier built between the garage and the roof. In two or more complete sentences, explain how these changes affect the model for the area of the roof's entire surface.
Answer:
Step-by-step explanation:
This will increase the roofs area by the garages area because, if the contractor does not put a roof to the garage then the garage can be considered part of the roof. This means that the roof's area is the normal area of the roof plus the area of the garage

Express 130 and 325 as the sum of two squares in two different ways.
Answer:
3^2 + 11^2 = 130
7^2 + 9^2 = 130
---
1^2 + 18^2 = 325
6^2 + 17^2 = 325
Step-by-step explanation:
We want to express 130 and 325 as the sum of two squares in two different ways.
Then, we want to find two integers a and b such that:
a^2 + b^2 = 130
There is not an analytical way to do this, we just need to try with different integers.
Let's start with 130.
So we start by defining a as a really small integer, for example 1, and try to find b.
1^2 + b^2 = 130
b^2 = 130 - 1
b^2 = √129 = 11.3
This is not an integer, so let's try with another value of a.
a = 2
2^2 + b^2 = 130
4 + b^2 = 130
b^2 = 130 - 4
b = √126 = 11.2
This can be discarded again.
Now let's try with a = 3
3^2 + b^2 = 130
9 + b^2 = 130
b^2 = 130 - 9
b = √121 = 11
Nice.
So we can express 130 as:
3^2 + 11^2 = 130
Now let's find another pair.
In the same way, we can see that for a = 7 we get:
7^2 + b^2 = 130
42 + b^2 = 130
b^2 = 130 - 49
b = √81 = 9
Then we can write:
7^2 + 9^2 = 130
Now for 325:
With the same reasoning than before, we want to find two integers such that:
a^2 + b^2 = 325
Then we start evaluating a by the smallest values:
a = 1
1^2 + b^2 = 325
b^2 = 325 - 1 = 324
b = √324 = 18
Then we can write 325 as:
1^2 + 18^2 = 325
Now to find the next pair we need to keep testing values for a, we will get for a = 6:
6^2 + b^2 = 325
36 + b^2 = 325
b^2 = 325 - 36 = 289
b = √289 = 17
Then we can write:
6^2 + 17^2 = 325.
The Petri dish shown has no lid. What is the surface area of the outside of the Petri dish? Round to the nearest tenth. A cylindrical-shaped Petri dish with a radius of 50 millimeters and a height of 15 millimeters.
Answer:
12566.4 mm²
Step-by-step explanation:
The Petri dish shown has no lid. What is the surface area of the outside of the Petri dish? Round to the nearest tenth. A cylindrical-shaped Petri dish with a radius of 50 millimeters and a height of 15 millimeters.
TSA = Total Surface Area
CSA = Curved Surface Area
TSA of open cylinder = CSA of cylinder + area of base or top
= 2πrh + πr²
= πr(2h + r)
From the above question:
r = 50mm
h = 15mm
Hence,
= π × 50 (2 × 15 + 50)
= π × 50 (30 + 50)
= π × 50(80)
= π × 4000
= 12566.370614mm²
Approximately = 12566.4 mm²
The Surface Area of the petri dish with no lid = 12566.4 mm²

Answer:
x = 5, y = 2.5
Step-by-step explanation:
Because the original image is scaling down 4, it means all of the values of the shape will be scaled down, or divided by 4.
20, which divided by 4, will make x equal 5.
10, which divided by 4, will make y equal 2.5

It is customary to leave a 15% tip for a waiter/waitress. Suppose your meal costs $22.50, What would you tip the wait person? How much totalwould you pay for the meal?
Answer:
$25.88
Step-by-step explanation:
Given data
Cost of meal= $22.50
Tip= 15%
Let us find 15% of $22.50
=15/100*22.50
=0.15*22.50
=3.375
Hence the amount you would pay in total is
=3.375+22.5
=$25.88

Mr. drew rides his motorcycle with a constant speed of 72 mi/hr. How far can he travel in 2 ½ hours?
Answer:
180
Step-by-step explanation:
take 72+72 +36 to get your answer .
Answer:
180 miles
Step-by-step explanation:
Assuming that the speed of the motorcycle is constant, the following equation, ([tex]speed * time = distance[/tex]) can be used to find the distance that a vehicle traveled when one is given the time and speed at which the vehicle operates. Substitute in these values, and solve,
[tex](72)*(2\frac{1}{2})\\\\= 72 * \frac{5}{2}\\\\= 180[/tex]

What is the value of x? Show me how you got that answer.
Answer:
x = 3
Step-by-step explanation:
The angle measuring 5x and the angle measuring 165° are a linear pair, so they are supplementary. Their measures add to 180°.
5x + 165 = 180
5x = 15
x = 3
El autobús mide 33,5 pies de largo. El tren de la ciudad es 45,9 pies más largo que el autobús. ¿Cuánto dura el tren de la ciudad
Respuesta:
79.4 pies
Explicación paso a paso:
Dado que :
Longitud del autobús = 33,5 pies
Longitud del tren = 45,9 pies más largo que el autobús
Por lo tanto, la longitud del tren es igual a:
Longitud del bus + 45,9 pies
33,5 pies + 45,9 pies
Longitud del tren = 79,4 pies
