Given:
Required:
To find the probability that the dart land will be in the shaded region.
Explanation:
Area of the circle is given by the formula:
Where r = radius
Thus the area of the circular region
The area of the square is given by the formula:
Thus the area of the given square
The probability of an event is given by the formula:
The probability that the dart land will be in the shaded region
Thus probability
Final answer:
Thus the probability that the dart land will be in the shaded region is 0.349.
Let the number of hamburgers = h
Let the number of cheeseburgers = c
Now we translate the given information into equations.
"combined total of 770 [ham]burgers and cheeseburgers"
h + c = 770
<span>"there were 70 more cheeseburger sold than hamburgers"
</span><span>
</span><span>c = h + 70
</span><span>
</span><span>
</span><span>Our system of equations is
</span><span>
</span><span>
</span><span />h + c = 770
c = h + 70
The second equation is already solved for c, so we replace c of the first equation with h + 70.
h + h + 70 = 770
2h + 70 = 770
2h = 700
h = 350
Answer: 350 hamburgers were sold on Monday.
There are enough information's already given in the question. Based on those information's that answer can be easily deduced.
Radius of the sphere = 8 units
Then
Surface area of the sphere = 4 *pi * r^2
= 4 * pi * (8)^2
= 4 * pi * 64
= 256pi
I hope that this answer has come to your help.
Question
The exchange rate at the post office is £1=€1.17 how many euros will you get for £280
Answer:
<h2>
327.6 €</h2>
Step-by-step explanation:
you can solve with an equation
1£ : 1.17€ = 280£ : x
1 : 1.17 = 280 : x
x = 1.17 * 280 : 1
x = 327.6
-------------------
check
1 : 1.17 = 280 : 327.6
0.85 = 0.85
the answer is good
------------------------------------
or you can simpy solve with a multiplication
280 * 1.17 = 327.6
Sine wave with amplitude 0.25
Period is 4/3
h(t) = 0.25Sin((2Pi/4/3)t) = 0.25Sin((3Pi/2)t)
