If the diameter of the smaller circle is 3.5cm, that means the radius is 1.75cm.
The area of the smaller circle is π × 1.75², which is ≈ <span>9.62112750162.
The diameter of the larger circle is 12.5 cm, so the radius would be half that, which is 6.25cm. The area of the larger circle would be </span>π × 6.25², which is ≈ <span>122.718463031.
So now that we know the area of the larger circle and the smaller circle, we can find the area of the shaded region by subtracting the area of the smaller circle from the area of the larger circle, which is basically just </span>122.718463031 - 9.62112750162, which is = 113.097336. The closest answer here is 113.04, hence the answer is 113.04cm².
If 18 inches is 20% less than the original length of the snake, then you can say that it is 80% of the original length. 18 inches ÷ 80% = 0.225, which would be 1% of the original snake. Now that you have 1%, all you need to do is multiply by 100 to get 100%, which is 22.5 inches, which is answer D. I hope this helps!
3 * N = 1
The multiplicative inverse is just the reciprocal of the number. The reciprocal is just " flipping " the number. So the reciprocal of 3 (or 3/1) is 1/3. And any time u multiply a number by its multiplicative inverse (reciprocal), the result is 1
3 * 1/3 = 3/3 = 1.....so N is ur multiplicative inverse
I have to make certain assumptions about what you mean here by your
3 ≤ 4 + 3 x / 2 ≤ 2: <span>3 ≤ 4 + 3x/2 ≤ 2. Is that correct or not?
If correct, let's elim. the fractions by mult. all 3 terms of this inequality by 2:
2(</span> 3 ≤ 4 + 3x/2 ≤ 2) => 6 ≤ 8 + 3x ≤ 4
Now subtract 8 from all three terms:
6-8 ≤ 8-8 + 3x/2 ≤ 2-8, or -2 ≤ 3x ≤ 4-8, or -2 ≤ 3x ≤ -4
Isolating x: -2/3 ≤ x ≤ -4/3
There's a basic problem here: -2/3 is not ≤ -4/3.
Please double check to ensure that you have copied down the original problem exactly as it was given.
