Answer:
[tex] r = 6\sqrt{3} [/tex]
Step-by-step explanation:
Area of the shaded section = θ/360*πr²
Area = 15π m²
θ = 360° - 310° = 50°
r = ??
If in the values into the equation and solve for r
15π = 50/360 × π × r²
[tex] 15 \pi = \frac{5 * \pi * r^2}{36} [/tex]
Multiply both sides by 36
[tex] 15 \pi * 36 = \frac{5\pi * r^2}{36}*36 [/tex]
[tex] 540 \pi = 5\pi * r^2[/tex]
Divide both sides by 5π
[tex] \frac{540 \pi}{5\pi} = \frac{5\pi * r^2}{5\pi} [/tex]
[tex] 108 = r^2 [/tex]
[tex] r = \sqrt{108} [/tex]
[tex] r = \sqrt{36*3} [/tex]
[tex] r = 6\sqrt{3} [/tex]

Use the graph to write the explicit rule of the arithmetic sequence
Answers
Answer:
It would be b.
Step-by-step explanation:
Plug in the numbers and try it out yourself. I did it and got b
The explicit rule of the arithmetic sequence is fₙ = 3 + 2(n-1) which is correct option(B).
What is arithmetic sequence?
An arithmetic sequence is defined as an arrangement of numbers which is particular order.
What is graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
According to the graph, we get the sequence
3, 5, 7, 9, ...
Here,
a₁ = 3 is the first element.
An arithmetic sequence has a constant difference 'd' and is defined by
fₙ = a₁ + (n-1)d
computing the differences of all the adjacent terms
5 - 3 = 2, 7 - 5 = 2, 9 - 7 = 2
The difference between all the adjacent terms is the same and equal to
d =2
substituting a₁ = 3 and d = -2 in the nth term of the sequence
fₙ = a₁ + d(n-1)
fₙ = 3 + 2(n-1)
Hence, the explicit rule of the arithmetic sequence is fₙ = 3 + 2(n-1).

Find the equation of the circle centered at $(1,-4)$ with radius 3.
Write your equation in the form "$(x - h)^2 + (y - k)^2 = r^2$".
Answers
Answer:
[tex](x-1)^2+(y+4)^2=9[/tex]
Step-by-step explanation:
The equation of a circle is given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where (h, k) is the center and r is the radius.
The center of the circle is (1, -4).
And the radius is 3.
Substitute:
[tex](x-(1))^2+(y-(-4))^2=(3)^2[/tex]

Answers
Answer:
112.5 divided by 15=7.5
112.5 divided by 15=7.5 equation is true answer.
Given option are:
15 divided by 112.5 = 7.5
15 ÷ 112.5 = 0.1333
This option is wrong.
15 divided by 112.5 = 75
15 ÷ 112.5 = 0.1333
This option is wrong.
112.5 divided by 15 = 7.5
112.5 ÷ 15 = 7.5.
This option is right.
112.5 divided by 15 = 75.
112.5 ÷ 15 = 7.5.
This option is wrong.

What is −3/4x−1/3+7/8x−1/2 written in simplest form?
Answers
Answer:
I love algebra anyways
The ans is in the picture with the steps how i got it
(hope this helps can i plz have brainlist :D hehe)
Step-by-step explanation:
The simplest form of expression - 3/4x - 1/3 + 7/8x - 1/2 is,
⇒ x/8 - 5/6
The given expression is,
⇒ - 3/4x - 1/3 + 7/8x - 1/2
Now, We can simplify the expression by combining like terms as,
⇒ - 3/4x - 1/3 + 7/8x - 1/2
⇒ - 3/4 x + 7/8x - 1/3 - 1/2
⇒ - 6/8x + 7/8x - 1/3 - 1/2
⇒ (- 6 + 7)x/8 - (1/3 + 1/2)
⇒ x/8 - (3 + 2)/6
⇒ x/8 - 5/6
Therefore, The simplest form of expression - 3/4x - 1/3 + 7/8x - 1/2 is,
⇒ x/8 - 5/6

Ruchi travelled 149 cm 415 in a week How much distance did she travel in a day
Answers
Answer:
171.85 cm
Step-by-step explanation:
Given data
We are given that the distance = 149 cm 415in
Let us mark the units uniform by converting inches to cm
1 inches = 2.54cm
415 inches= x cm
cross multiply
x= 415*2.54
x= 1054.1 cm
Hence the total distance in cm is 1054.1+149= 1203cm
If in 7 days he travels 1203cm
in 1 day he will travel x cm
cross multiply
7x= 1203
divide both sides by 7
x= 1203/7
x= 171.85 cm
