El perímetro de una circunferencia es de 40π cm, y tiene un ángulo de 130°. Calcula el área del sector de dicha circunferencia.
Answer:
Area of sector = 144.4π cm²
Step-by-step explanation:
Given:
Perimeter of circle = 40π cm
Given angle = 130°
Find:
Area of sector
Computation:
Perimeter of circle = 2πr
⇒ 40π = 2πr
⇒ 40 = 2r
⇒ Radius r = 40 / 2
Radius r = 20 cm
Area of sector = [θ/360][π][r]²
⇒ Area of sector = [130/360][π][20]²
⇒ Area of sector = [0.361][π][400]
Area of sector = 144.4π cm²

Answer:
416 mi
Step-by-step explanation:
In order to find the surface area, you must find the area of each square. There are a total of 6 that make up the prism.
Remember to find the area it is length x width
9 x 8 = 72 which is the area for 4 of the squares. 2 on the side and 2 on the bottomLastly for the last 2 squares to find the area you multiply 8 x 8 = 64In total, you will add 72+72+72+72+64+64 which equals 416Maria says that the solutions of the inequality are y.

The answer is 9.1 or if you don't want a decimal then, 9.
Step-by-step explanation:
10% ?
___ ___
100 91
First:
you make them into fractions (hint: 100 is ALWAYS the denominator of your percent)
Second:
You multiply 10 and 91 which gives you 910
Third:
910
___
100
You put the fractions like this and cross out the two zeros to get this:
91
__
10
Lastly you divide 91 and 10 which gives you 9.1 and if you don'y want a decimal then round it to the nearest whole number which gives you 9.
Hope this helps!! =3

Shirts are on sale for 30% off. The original price of one shirt is $15. What is the total cost, in dollars, of 2 of these shirts at the sale price, including a 7% sales tax?
Answer:
I pretty sure the answer is $22.47
Step-by-step explanation:
15+15=30-30%=21+7%=22.47
Answer:
Hi ! The answer to your question would be $23.54
Step-by-step explanation:
30% off of $15 would bring you to $10.50, if you add $10.50 twice u would get $21. The 7% sales tax would be $2.54, adding that to $21 you get $23.54
12x−5y=−20 y=x+4 x=x=x, equals y=y=y, equals
Answer:
The solution is (0, 4)
Step-by-step explanation:
Please pay attention to the first two equations and drop the last two:
12x−5y=−20 y=x+4 x=x=x, equals y=y=y should ideally be:
12x−5y=−20
y=x+4
Let's find x. Substitute x + 4 for y in the first equation, obtaining:
12x - 5(x + 4) = -20
Carrying out the indicated multiplication, we get:
12x - 5x - 20 = -20, or 7x = 0
If x = 0 then y must be 0 + 4, or 4.
The solution is (0, 4)
Answer:x=0 y=4

Isaac paid $81 for a new surfboard. The amount paid was 60% of his total savings. How much money did he have in his savings before buying the surfboard?
Answer:
$135
Step-by-step explanation:
Given data
Amount paid for new surfboard= $81
Percentage of the savings paid= 60%
Let the amount of the savings be x
Hence
60% of x= 81
60/100*x= 81
0.6x=81
x= 81/0.6
x=$135
Hence his savings was $135

WORK!!!
60 mm
14 in
SOT
Answer:
A=630 in^2
Step-by-step explanation:
Triangles: there are two equal triangles so we can treat them as one rectangle
A = 15 * 14 = 210
Rectangle:
A=30 * 14 = 420
A_total = 210 + 420 = 630 in^2
The perimeter of a rectangle is 16x – 6. If the length is
5x + 2, what is the width?
Answer:
3x + 1
Step-by-step explanation:
5x + 2 × 2 = 10x + 4
do this take 16x - 6
you get 6x + 2
then divide by 2 to get the answer 3x+1
Answer:
w = 3x - 5
Step-by-step explanation:
Perimeter of a rectangle formula:
P = 2(l + w)
16x - 6 = 2(5x + 2 + w)
16x - 6 = 10x + 4 + 2w
2w = 16x - 6 - 10x - 4
2w = 6x - 10
w = 3x - 5
