Find the sum of the first 48 terms of the following series, to the nearest integer.
6, 9,12,...
6,9,12
Answer:
3,672
Step-by-step explanation:
Given the sequence 6, 9, 12...
The sequence is an arithmetic sequence
first term a = 6
common difference d = 9 - 6 = 12 - 9 = 3
number of terms n = 48
Sn = n/2[2a+(n-1)d]
Substitute the given values
S48 = 48/2[2(6)+(48-1)(3)]
S48 = 24(12+(3*47))
S48 = 24(12+141)
S48 = 24(153)
S48 = 3,672
Hence the sum of the first 48terms is 3,672
Need help ASAP please
Answer:
because the length is 4 feet more than the width
=> the length is x + 4 (feet)
because the base has an area of 21 square feet
=> x(x + 4) = 21
<=> x² + 4x = 21

area of shaded sector =
area of unshaded sector =
Answer:
Area of the unshaded sector = 113.4 sq units
Area of the shaded sector = 200.6 sq units
Step-by-step explanation:
First let us calculate the area of the circle
Area of the circle = πr²
radius r = 10units
Area of the circle = π(10)²
Area of the circle = π(100)
Area of the circle = 3.14(100)
Area of the circle = 314 sq. units
Area of a sector = theta/360 * πr²
Area of the unshaded sector = 130/360 * 314
Area of the unshaded sector = 13/36 * 314
Area of the unshaded sector = 113.389 sq units
Area of the unshaded sector = 113.4 sq units
Area of the shaded sector = Area of circle - Area of the unshaded sector
Area of the shaded sector = 314 - 113.89
Area of the shaded sector = 200.6sq. units

find the area of the figure. use 3.14 for pi <3
Answer:
23.13m^2
Step-by-step explanation:
We'll use 3.14 for pi as instructed.
We can rearrange the figure to one square and 2 full circles.
Area of the square is 3m*3m = 9m^2
Area of a single full circle is pi*1.5m*1.5m = pi*2.25m^2 = 3.14*2.25m^2 = 7.065m^2
Full area = 9m^2 + 2*7.065m^2 = 9m^2 + 14.13m^2 = 23.13m^2
Answer:
23.14

Find the area of a regular decagon with a perimeter of 60 ft.
Answer:
Area of a regular decagon with a perimeter of 60 ft. = 277 squared ft
Step-by-step explanation:
Decagon has 10 sides So 60/10 = 6 (each side = 6ft )
The sum of the interior angles of a decagon is 1 440 degrees.
There are 10 equal isosceles triangles of base angles 72 degrees in a decagon
Each isosceles triangle can subdivided into 2 right-angled triangles with height h and base length = (6/2) = 3 cm and base angle 72 degrees.
Height of right-angled triangle h = 3 tan 72 ft.
Area of 1 right-angled triangle = (1/2)(3)(3 tan 72) = 13.85 squared ft
Area of decagon = 20 right-angled triangles = 277 squared ft

Piper signed up for a streaming music service where there's a fixed cost for monthly
membership and a cost per song downloaded. Her total cost per month is given by
the equation c =
0.5x + 2.99, where x represents the number of songs she
downloads and c represents the total cost, in dollars and cents. What could the
number 0.5 represent in the equation?
Answer:
I think the answer is 0.5 rate/number of songs she downloads. Sorry if I am wrong
Step-by-step explanation:
0.5x means that 0.5 is our rate and the question states that x represents the number of songs she downloads
Which of the following is a solution to the system of
equations?
4 + y = -x
y = 2x - 10
Answer:
x=3, y= -6
Step-by-step explanation:
make 4+y= -x as equation (1) and make y=2x-10 as equation (2, then you must find a third equation either from equation (1)or (2). If you choose to find equation (3) from (2) it will be y=2x-10 , then substitute equation (3) from (1) because you can't choose (2) , then it will be 4+(2x-10)= -x
the answer will be x =2
substitute x from equation (3)
y=2x-10
y=2 (2)-10
y= -6

What is the approximate volume of the pyramid?
9514 1404 393
Answer:
6300 m³
Step-by-step explanation:
The volume of the pyramid is given by the formula ...
V = 1/3s²h
where s is the side length of the square base, and h is the height.
V = 1/3(30 m)²(21 m) = 6300 m³
The approximate volume of the pyramid is 6300 m³.
