Find the area of the shaded region. Round to the nearest hundredth where
necessary. Show work
Answer:
look at the picture i have sent
The area of the shaded region is 192.325 m².
What is area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.
We have,
Outer radius = 21/2 = 10.5 m
Inner radius = 10.5 - 3.5 = 7 m
So, Area of shaded region
= π( R² - r²)
= 3.14 (10.5² - 7²)
= 3.14 (110.25 - 49)
= 192.325 m²

D. 35 units2
SUBMIT
Answer:
the answer is c or 45pie Units
Step-by-step explanation:
The surface area of the right cone is,
⇒ SA = 45π units²
What is mean by Multiplication?The multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
We have to given that;
Radius of cone (r) = 3 units
Slant height of cone (l) = 12 units
Now, We know that;
The formula that is used to calculate the surface area of a cone is;
⇒ SA = πrl + πr²
Hence, We can substitute all the values we get;
⇒ SA = πrl + πr²
⇒ SA = π × 3 × 12 + π × (3)²
⇒ SA = 36π + 9π
⇒ SA = 45π units²
Thus, The surface area of the right cone is,
⇒ SA = 45π units²

Answer:
There are 60 hockey cards (1/4 of 240)
Step-by-step explanation:
1/3 of 240 is 80
1/6 of 240 is 40
1/4 of 240 is 60
80+40+60 = 180
240 - 180 = 60

PQ is tangent to the circle and m
Answer:
x = 78°
Step-by-step explanation:
m<P = 12°
Since PQ is tangent to the circle at point Q, therefore m<Q = 90° (tangent theorem)
x + m<P + m<Q = 180° (sum of triangle theorem)
Substitute
x + 12° + 90° = 180°
x + 102° = 180°
Subtract 102° from each side
x = 180° - 102°
x = 78°

The amount of money in an account may increase due to rising stock prices and decrease due to falling stock prices. Marco is studying the change in the amount of money in two accounts, A and B, over time.
The amount f(x), in dollars, in account A after x years is represented by the function below:
f(x) = 10,125(1.83)x
Part A: Is the amount of money in account A increasing or decreasing and by what percentage per year? Justify your answer. (5 points)
Part B: The table below shows the amount g(r), in dollars, of money in account B after r years:
r (number of years) 1 2 3 4
g(r) (amount in dollars) 9,638 18,794.10 36,648.50 71,464.58
Which account recorded a greater percentage change in amount of money over the previous year? Justify your answer. (5 points)
Answer:
It looks like your first account increases linearly,
unless you have a typo and meant:
f(x) = 10,125(1.83)^x
the second
exponential and can be written as
g(r) = 9,638(1.95)^r
clearly g(r) has a higher percentage change since 1.95 > 1.83
a more interesting question might have been: When will the amount be the same?
10,125(1.83)^x = 9,638(1.95)^x
10,125(1.83)^x = 9,638(1.95)^x
(1.83)^x = .951901...(1.95)^x
take log of both sides and use log rules
xlog1.83 = log .951901... + log 1.95
x(log 1.83 - log 1.95) = log .951901...
x = .776..
check:
f(.776..) = 10,125(1.83)^.776.. = 1618410
g(.776..) = 9,638(1.95)^.776... = 16184.10

Which of the following is a graph of y < x + 3?
For each ordered pair, determine whether it is a solution to 2x - 5y=11.
Is it a solution?
(x, y)
(3, -1)
(-7,-5)
(-9,4)
(4,2)
Answer:
(3, -1)
Step-by-step explanation:
The solution of the equation are (3, -1) and (-7, -5).
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have Equation, 2x- 5y= 11.
To check each ordered pair is the solution of equation then we have put the value of x and y one by one in the given equation.
1. x =3 and y= -1
2(3)- 5(-1)
= 6 + 5
= 11
2. x= -7 and y=-5
= 2(-7) - 5(-5)
= -14 + 25
= 11
3. x= -9 and y= 4
= 2(-9)-5(4)
= -18 - 20
= -38
4. x = 4 and y= 2
= 2(4) - 5(2)
= 8 - 10
= -2
Thus, the solution of the equation are (3, -1) and (-7, -5).

A triangle has sides with lengths 17, 12, and 9. Is the triangle right, acute, or obtuse?
Question 1 options:
A)
Can't be determined
B)
Obtuse
C)
Right
D)
Acute
Answer:
b) obtuse
Step-by-step explanation:
If this is a right triangle the hypotenuse would be
c² = 9² + 12²
c² = 81 + 144
c² = 225
c = √225
c = 15
Since the third side is 17 which is longer than 15
the triangle is obtuse
Answer:
obtuse
