Answer:
Perimeter = 9700 cm
Step-by-step explanation:
Dimensions of sides are;
12, 2x, 12, 5, 5, circumference of semi circle
Now, the semi circle has a radius of 7. Thus, the diameter = 7 × 2 = 14
We see that x is the diameter. Thus, x = 14
Thus; base of trapezium that is 2x = 2 × 14 = 28
Also, circumference of semi circle = 2πr = 2π × 7 = 44
Thus;
Perimeter of shape = 12 + 2(14) + 12 + 5 + 5 + 44
Perimeter = 97 m
Converting to cm, we multiply by 100 to get;
Perimeter = 97 × 100 cm
Perimeter = 9700 cm
Answer: 0.0081
Step-by-step explanation:
Let X be the number of rafts.
Given : The mean number of rafts floating :
rafts per day .
Then , for 7 days the number of rafts =
rafts per day .
The formula to calculate the Poisson distribution is given by :_

Now, the probability that they will have to wait more than a week is given by :-

Hence, the required probability : 0.0081
Answer:
y + 12
Step-by-step explanation:
1. remove parentheses.
10 + 2 + y
2.collect like terms.
y + ( 10 + 2)
3. simplify.
y + 12
Therefor, the answer is. y + 12
15% off means the sale price is 85% of the original price.
Divide the sale price by the percent of original price:
3825/0.85 = 4,500
answer : £4,500
I think the answer is he payed $3.40
