Answer:
You increase each term inside the parentheses by -1 in order to subtract each term, since the subtraction is the additive inverse
Answer:
3/2
Step-by-step explanation:
3/4÷1/2=3/2
Do you have a better graph I could see
Answer:
377 square centimeters
Step-by-step explanation:
Formula: h(2×pi×radius) I know there's a second part but I'm doing this first.
First find the radius, in the problem it says a diameter of 10cm
Divide 10 by 2 to find the radius = 5
I'm going to use 3.14 as Pi
7(2×3.14×5)
7(31.4) = 219.8
Next part, solving for the 2 circles
Formula: 2×pi×radius²
2×3.14×5²
solve 5² first (5×5) = 25
2×3.14×25 is 157
add 219.8 and 157 = 376.8 round to 377
Answer: 377 square centimeters
Answer:
x = 25
Step-by-step explanation:
Assuming Angle A, B and C are angles in a triangle.
∠A + ∠B + ∠C = 180º
(2x - 20) + (120) + (x + 5) = 180
2x - 20 + 120 + x + 5 = 180
3x + 105 = 180
3x = 75
x = 25
