y=6
Answer:
75% (Letter grade = C)
Step-by-step explanation:
- 15 ÷ 20 = 0.75
- Multiply by 100: 0.75 × 100 = 75
- So, your grade was a 75% (letter grade = C)
Answer:
(a, 0)
Step-by-step explanation:
As S is on the x-axis, its y-coordinate will be zero.
And since this is a right trapezoid, ∠QPS and ∠PSR are right angles, so S and R will have the same x-coordinate, which is a.
Therefore, the coordinate of Point S is (a, 0)
Answer:
489.84 m²
Step-by-step explanation:
Area of one 2d circle: πr² ⇒ π6² ⇒ 36π ≈ 113.04 (using 3.14 for pi)
Area of both 2d circles: 113.04 + 113.04 =226.08 m²
Now we have to find the width of the rectangle, which is equal to the circumference of either circle:
Width of rectangle: 2πr ⇒ 2π6 = 12π ≈ 37.68 (using 3.14 for pi)
We can find the area of the rectangle now, since the length was given
Area of rectangle: 37.68· 7= 263.76 m²
Surface Area: 263.76+226.08= 489.84m²
Hopefully this helps!
