Answer: A=448+196pi, P=60+14pi
Step-by-step explanation:
I'm assuming that the figures which appear to be semicircles are semicircles and that the quadrilateral is a rectangle.
The perimeter is 16 + 16 + 28 + (28/2)(pi)= 60+14pi
area is area of rectangle + area of semicircle
= (16)(28)+(pi)(14)(14)=448+196pi

In this question, we're trying to find the probability of it being cloudy and raining.
In this case, we know that:
- Probability of it being cloudy is 30%
- Probability of it raining is 25% (this is necessarily not needed)
- If it's cloud, the probability of it raining is 45%
With the information above, we can find the probability.
We know that from a 100% scale, the chance of it being cloudy is 30%.
We know that if it's cloudy, the chances of raining is 45%
To find the probability of it being cloudy and raining, we would multiply 0.3 (30%) by 0.45 (45%)
Solve:
Your answer would be C). 13.5%

Answer:
84%
Step-by-step explanation:
Henry completed a total of 50 questions. From these 50 he predicted 36 were right and this means he also predicted that 14 were wrong (50-36 = 14). From these predictions 5 out of 36 from the ones that he predicted were right were actually wrong and 3 of the 14 questions (14-11 = 3) he predicted were wrong were actually right. Meaning in total he wrongly predicted 8 questions which means he predicted 42 correctly ...
42 / 50 = 0.84 = 84%
Therefore, Henry's prediction accuracy is 84%
110 students are going on a trip, and each student needs one water bottle.
So we multiple 110 students* 1 water bottle each to get 110 water bottles are needed for all the students.
There are 6 water bottles in a pack- and we need 110 water bottles.
So divide the number of water bottles needed by the amount in a pack.
110/6= 18 1/3
We need 18 packs a little bit more- so we round 18 up because we can't buy 1/3 of a pack or have students go thirsty.
So we need 19 packs of water for the students on the trip.
