Answer:
0.50
Step-by-step explanation:
Do the opposite of addition
So 1.25 - 0.75
Speed = distance / time
Speed = 182.4 / 3
Speed = 60.8 miles per hour.
Answer: Interval E
Step-by-step explanation:
I took the test and it is Interval E cause the line is decreasing/going down
Answer:
Step-by-step explanation:
slant height l =√(20²+(9/2)²)=√(400+81/4)=√(1681/4)=41/2
slant surface area=πrl
base area=πr²
Total surface area=πr²+πrl=πr(r+l)=π×(9/2)(9/2+41/2)=π×(9/2)×50/2=225π/2
=225×3.14/2
=225×1.57
=353.25 mm²
In the picture, it is a semicircle, so you have to remember to divide the area by 2.
The diameter of the circle is 18, so the radius is 9. Using the formula, I'll find the area.
9²π=81π= 254.34÷2= 127.17
Now finding the radius actually help, because that semicircle's height is its radius, which is 9.
18 ×9 = 162
Now I'm going to find the shaded area.
162 - 127.17 = 34.83 mm²
