Step-by-step explanation:
Find the area of all shaded regions. Give your answer as a completely simplified exact value in terms of pi. (no approximations)
To find the area of the shaded region, you first use the equation A = πr²
The radius of the circle is 9 cm. So A = π(9²)
A = 3.14 (81)
A = 254.34 (entire circle)
The entire circle is 360°
and 4.5 of the 80°'s will equal 360°
254.34 ÷ 4.5 = 56.52
ANSWER: 56.52 cm²
Answer:
56.55 cm^2
Step-by-step explanation:
Since a circle is 360 degrees and the piece is 80 degrees, the shaded area is 4.5 of the total area of the circle (9/2). Find the area of the circle:
[tex]\pi r^{2}[/tex]
[tex]\pi 9^{2}[/tex]
[tex]\pi 81[/tex]
[tex]254.47/4.5[/tex]
56.55 cm^2

Stephanie put $80 in her bank account when she was 5
years old. The bank gave her a simple interest rate of 2.1%.
Does she have enough money to buy a TV for $1,000 after
leaving her money in the bank for ten years?
Answer:
Mynd44
Step-by-step explanation:
Here, we want to check if the amount of money saved is enough to
by a tv
Mathematically, we have the simple interest formula as follows;
I = PRT/100
I = (80 * 2.1*10)/100
I = 1680/1000 = 1.68
Hence, she will not have enough

Answer:
2/3
Step-by-step explanation:
Consider the line with a slope of -1 through the point (-1,3).What is the y-intercept (b) of the line
Answer:
y = -x + 2
Step-by-step explanation:
slope = -1 ; (-1 , 3)
Equation: y - y1 = m (x - x1)
y - 3 = (-1)(x -[-1])
y - 3 = (-1) (x + 1)
y - 3 = -x - 1
y = -x - 1 + 3
y = -x + 2
Answer:
y=-x+2

A recommendation for wheelchair ramps is that the rise-to-run ratio be no greater than 1:12. This ensures that the ramps are navigable by people in wheelchairs. If a business needs to install a concrete ramp to the entrance of their building, which is 12 inches off the ground, how long should the ramp be and how far out horizontally on the ground will it protrude from the building? Give answers in feet and inches, such as 5 feet, 4 inches. What percent grade is the ramp?
Answer:
a. 12 feet b. 12 feet 0.5 inches c. 8.33 %
Step-by-step explanation:
a. How far out horizontally on the ground will it protrude from the building?
Since the rise to run ratio is 1:12 and the building is 12 inches off the ground, let x be the horizontal distance the ramp protrudes.
So, by ratios rise/run = 1/12 = 12/x
1/12 = 12/x
x = 12 × 12
x = 144 inches
Since 12 inches = 1 foot, 144 inches = 144 × 1 inch = 144 × 1 foot/12 inches = 12 feet
b. How long should the ramp be?
The length of the ramp, L is gotten from Pythagoras' theorem since the ramp is a right-angled triangle with sides 12 inches and 144 inches respectively.
So, L = √(12² + 144²)
= √[12² + (12² × 12²)]
= 12√(1 + 144)
= 12√145
= 12 × 12.042
= 144.5 inches
Since 12 inches = 1 foot, 144.5 inches = 144 × 1 inch + 0.5 inches = 144 × 1 foot/12 inches + 0.5 inches = 12 feet 0.5 inches
c. What percent grade is the ramp?
The percentage grade of the ramp = rise/run × 100 %
= 12 inches/144 inches × 100 %
= 1/12 × 100 %
= 0.0833 × 100 %
= 8.33 %

A) 1/3 cake
B)1/6 cake
C) 1/9 cake
D) 1/12 cake
Answer:
1/9
Step-by-step explanation:
Divide 1/3 divided by 3 (1/9)
Keep, Change, Flip
(Keep the first fraction, change the division sign to multiplication sign, flip the last fraction)
The equation would be
1/3*1/3=1/9

4x+3y=5
2x+3y=1
x=?
y=?
Answer:
x = 2, and y = -1. Point form: (2, -1)
Step-by-step explanation:
You solve the system of equations, by solving for one variable, and then subsitiute that variable into the other equation.
The value of x = 2
The value of y = -1
What is an 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.
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.
Given data ,
Let the first equation be = A
Let the second equation be = B
Now , we have two equations
4x + 3y = 5 be equation (1)
2x + 3y = 1 be equation (2)
Now , on simplifying the equations , we get
Subtracting equation (2) from equation (1) , we get
2x = 4
Divide by 2 on both sides , we get
x = 2
Substitute the value of x in equation (1) , we get
4 ( 2 ) + 3y = 5
8 + 3y = 5
Subtract 8 on both sides , we get
3y = -3
Divide by 3 on both sides , we get
y = -1
Therefore , the value of x and y is 2 and -1 respectively
Hence , The value of x = 2
The value of y = -1
