Total area is 102.3 yd²
Step-by-step explanation:
Total area = area of the parallelogram + area of the right triangle
Calculate the area of the parallelogram.
Base = 11 yd, Height = 6.2 yd
⇒ Area of the parallelogram = Base × Height = 11 × 6.2 = 68.2 yd²
Calculate the area of the right triangle.
Height = 6.2 yd, Base = 11 yd (Since opposite sides of a parallelogram are equal)
⇒ Area of the triangle = 1/2 × base × height = 1/2 × 11 × 6.2 = 34.1 yd²
Calculate the total area.
⇒ Total area = 68.2 + 34.1 = 102.3 yd²
Answer:
25.12
Step-by-step explanation:
The circumference of the circle is : 2 × pi × r
Diameter = 8 feet
Radius= diameter / 2
r = 8 / 2
r= 4
Therefore
The circumference is :
= 2 × pi × r
= 2× 3.14 × 4
=25.12

Answer:
12 hours
Step-by-step explanation:
First to solve this problem, let's look at what we are dealing with here. It says that Ali made $126 for 9 hours of work.
Let's set that up into a fraction so it's easier to look at.
money/time = 126/9
Now that we have that set up let's look at our other piece of information.
It asks for how many hours would Ali have to work in order to make $168 so let's figure that out.
In order to find out the number of hours, let's first find our unit rate which can be simply found by dividing our given money/time.
126/9 = 14.
This means that for every 1 hour, there will be 14 dollars earned.
Now that we know that, let's look for how many hours it take to earn $168.
In order to do that simply see how many times 14 goes into 168 (division) and that way you can see how many hours it will take to earn $168.
168/14 = 12 hours.
Answer:
0.0791
Step-by-step explanation:
student forgets iClicker device with probability 1/4 each time she attends a class.
She sets out with her iClicker device to attend 5 different classes
A - forget device
A' - do not forget device
P(A) = 1/4
P(A') = 3/4
If she arrives home without her iClicker device (after attending 5 classes), what is the probability (to 3 SIGNIFICANT figures) that she left it in the 5th class?
So, she will not forget in 1st class AND not forget in 2nd class AND not forget in 3rd class AND not forget in 4th class AND will forget in 5th class, so:
1st 2nd 3rd 4th 5th
3/4 3/4 3/4 3/4 1/4 = 0.0791
