If u see circle make 360° as a whole
So 45 ° is 1/8th of the entire angle
If u find whole area of a circle= pi×r^2
r=4 ft
A= 16π
So divide it by 8
A= 2π feet^2
The width would be 22. Add 18+18 to get both of the sides for height which is 36z Then, subtract that from 58 which equals 22.
Answer:
1.x=0, –10
2.x=3, 4
Step-by-step explanation:
1.
x(x+10)=0===> x=0, –10
2.
x²–3x–4x+12===> x²–7x+12=0
(x–3)(x‐4)=0====> x=3, 4
Answer:
Number of boys in the class is (2/2+3)*25=(2/5)*25=10
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
To find what the number is, we can put the given information into an equation. We know that the number minus 6 equals -11. Lets use the variable x to represent the number. This would be the resulting equation:
x - 6 = -11
So now we solve for x to find our solution.
x - 6 = -11
Add 6 to both sides.
x = -5
So the answer would be B, -5.
