Answer:
Therefore,
The area of the sector is 15.09 unit².
Step-by-step explanation:
Given:
Circle with,
radius = r = 6 unit
central angle = θ = 48°
pi = 3.143
To Find:
Area of sector = ?
Solution:
If 'θ' is in degree the area of sector is given as
Substituting the values we get
rounded to nearest hundredth
Therefore,
The area of the sector is 15.09 unit².

Answer:
B, x=3 y=5
Step-by-step explanation:
x=-7+2y
3y+2x=21
Substitute the x into the other equation
3y+2(-7+2y)=21
y=5
Now put the value into a desired equation
x=-7+2(5)
x=3.
The answer is x=3 and y=5
I hope this helped!
Work only with the second equation at the beginning. Solve for x for it.
7x - 2x = 3 Combine the left hand side.
5x = 3 Divide by 5
5x/5 = 3/5 Do the division
x = 3/5 = 0.6
==============
Now work with the top equation.
3(0.6) + 5y = 13 Multiply on the left.
1.8 + 5y = 13 Subtract 1.8 from both sides.
1.8 - 1.8 + 5y = 13 - 1.8 Do the subtraction
5y = 11.2 Divide by 5
5y/5 = 11.2/5
y = 2.24 Answer
Answer:
N=0.019666a-0.983284 or
A = 50.85n + 50
Step-by-step explanation:
Let's solve for n.
a = 50 + 50.85n
Step 1: Flip the equation.
50.85n + 50 = a
Step 2: Add -50 to both sides.
50.85n+50+-50=a+-50
50.85n n = a - 50
Step 3: Divide both sides by 50.85.
50.85n
50.85
=
a-50
50.85
n=0.019666a-0.983284
Let's solve for a.
a = 50 + 50.85n
