Lara can read 10 chapters in 4 hours.
At this rate, she can read half that many chapters in half the time.
So she reads 5 chapters in 2 hours.
So Lara reads 10 chapters in 4 hours,
+ 10 chapters in 4 more hours,
+ 5 chapters in 2 more hours.
That's 25 chapters in total, and 10 hours in total, ya? :)
1/2 divide by 5= 1/10
1/4 divide by 5= 1/20 so 1/10 is also 2/20+1/20=3/20
so the answer is 3/20 of a pizza
hope this helped and plz leave a thank you
The answer to this question is d
Answer:
Step-by-step explanation:
m∠2 = 52° [Alternate interior angles]
m∠1 + m∠2 = 180° [Linear pair of angles are supplementary]
m∠1 = 180° - 52°
m∠1 = 128°
m∠3 = 47° [Alternate interior angles]
m∠5 + 52° + 47° = 180° [Sum of linear angles is 180°]
m∠5 = 180° - 99°
= 81°
m∠4 + 47° = 180° [Sum of consecutive interior angles is 180°]
m∠4 = 180° - 47°
m∠4 = 137°
The formula for the surface area of a cylinder is:
2<span>π</span><span>r</span><span>h </span><span>+ </span><span>2</span><span>π</span><span>r^</span><span>2
If we substitute in the measurements that we know, you get:
2</span><span>
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
(3.5) (14) + 2</span><span>
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
(3.5)^2
If we simplify this expression, we get:
98</span><span>
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
+ 24.5</span><span>
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
If you simplify once more, you get
122.5</span><span>
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
or </span><span>≈ 384.85
Therefore, the surface area is 122.5</span>
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
or about 384.85<span>
