Find the area of the square
Find the area of the circle
Subtract the area of the circle from the area of the square.
area of square = 10 x 10 = 100 sq. Cm
Area of circle = pi x r ^2 = 3.14 x 5^2 = 78.5 sq. Cm
area of shard region = 100 - 78.5 = 21.5 cm^2
The area of it is 78.5cm²
You can find the area of a circle by using the formula: pi • radius squared
In this case, the question states to use 3.14 for pi so our equation would look like:
3.14 • 5 • 5 (5 squared is same as 5 times5)
And that is how you get 78.5cm²

A 45-45-90 triangle is a special type of isosceles right triangle that has angle measures of 45°, 45°, and 90°. Every 45-45-90 triangle has the same ratio of side lengths. If the legs of a 45-45-90 triangle are a, write an expression for the length of the hypotenuse.
Answers
Answer:
[tex]a\sqrt{2} =h[/tex]
Step-by-step explanation:
The expression for the length of the hypotenuse is 2x.
Where x is any positive integer.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
An isosceles right triangle has angle measures of 45°, 45°, and 90°.
This means,
Two sides opposite to the equal angles are equal.
Now,
Equal sides = M
Hypotenuse sides = N
Now,
Every 45-45-90 triangle has the same ratio of side lengths.
This means,
Angles ratio:
45 : 45 : 90 = 1 : 1 : 2
Similarly,
Sides ratio:
M : M : N = 1x : 1x : 2x
Thus,
The expression for the length of the hypotenuse is 2x.
Where x is any positive integer.

The base of the exponential function is 3.
How to identify the base?Here we have the graph of an exponential function of the form:
f(x) = b^x
We want to find the value of b.
Remember that any number with an exponent of 1 is equal to the number:
a^1 = a
Then, we will have:
f(1) = b^1 = b
If you look at the graph, you can see that when x = 1, the function is equal to 3.
Then:
f(1) = 3 = b
From this, we can conclude that the base is equal to 3.

Original price $69.80 with a 15% discount, what is the new price.
Answers
Answer:
$59.33
Step-by-step explanation:
To begin, let's start with what we know
Item = 69.80
Discount = 15% or 0.15
So, let's put it into this formula
New Price = Item ( 1 - Discount) Note: P is the final price
= 69.80 ( 1 - 0.15)
= 69.80 ( 0.85 )
= 59.33
The new price is $59.33.
If you have any questions, please let me know in the comments. If you could mark this answer as the brainliest, I would greatly appreciate it!
Answer:
$59.33
Step-by-step explanation:
To find the new price, we need to know what is 15% of 69.80, and then subtract the result from 69.80. To find the percent, we multiply the number by the percent using decimals for the percent. 15% is 0.15, so we multiply 69.80 * 0.15 = 10.47
Next, subtract 10.47 from 69.80.
69.80 - 10.47 = 59.33
The new price is 59.33.
Another method is that since 69.80 is 100 percent, then the new price will be 100% - 15% = 85%. Multiply the 85 percent by 69.80, and find your answer.
0.85 * 69.80 = 59.33

In how many different ways can a committee with 2 members, be chosen from a group of 4 people?
Answers
Answer:
Step-by-step explanation:
We need 2 people out of a group of 4
Let's take a random person, and another to group with the random person we picked. We can group them with 3 different people ( 3 ways )
Now, repeat again, and pick a person to group with the person who is grouped with the first person (except the first person themself) (2 ways)
And repeat again, you will group them with the last person.
So in total, you have 3 + 2 + 1 = 6 ways to pick 2 people from a group of 4.

A bus leaves a bus station at 9:00 am and travels on the Eastbound Highway. A second bus leaves the same bus station 45 minutes later and travels in the same direction on the same highway at a speed of 20 kilometers per hour faster than the first bus. The second bus catches up with the first bus at 12:00. How fast was each bus traveling? (Include units in your answer. ) A. [3 pts) Define variables to represent the unknowns and setup the necessary equations to answer the question
Answers
The speed of the first bus is 60 km/h while the speed of the second bus is 80 km/h.
SpeedSpeed is the rate of change of distance with time. It is given by:
Speed = distance / time
Let a represent the speed of the first bus, and b represent the speed of the second bus.
b = a + 20
At 12:00, t = 3 hours, hence:
a = d/3
d = 3a
Also:
b = d/2.25
d = 2.25b
3a = 2.25b
3a = 2.25(a + 20)
a = 60
b = 60 + 20 = 80
The speed of the first bus is 60 km/h while the speed of the second bus is 80 km/h.
