I can't answer the question without the example provided, but here are some steps to solve it.
Basic info-
Circumference (C)
3.14 is used for pi π= 3.14
The line halfway of the circle is the radius(r)
The line through the circle is the diameter(d)
Formulas:
C= 2πr

Carter needs to remove sod in his yard to build three flower beds. One bed will be a rectangle which measures 2.5 m by 6 m. Another bed will be a semicircle which has a diameter of 6 m. The other bed will be a quarter circle with a radius of 4 m.
Answers
Answer:
[tex]Area = 41.714[/tex][tex]m^2[/tex]
Step-by-step explanation:
Given
Rectangle:
[tex]Length = 2.5m[/tex]
[tex]Width = 6m[/tex]
Semicircle
[tex]Diameter = 6m[/tex]
Quarter circle
[tex]Radius = 4m[/tex]
Required
The square meters of sod will Carter remove [Missing information]
To do this, we simply calculate the area of each flower beds.
For the rectangle:
[tex]A_1= Length * Width[/tex]
[tex]A_1= 2.5m * 6m[/tex]
[tex]A_1= 15m^2[/tex]
For the semicircle
[tex]A_2 = \frac{1}{2}\pi r^2[/tex]
Where
[tex]r=\frac{6}{2} = 3[/tex]
So:
[tex]A_2 = \frac{1}{2} *\frac{22}{7} * 3^2[/tex]
[tex]A_2 = \frac{1}{2} *\frac{22}{7} * 9[/tex]
[tex]A_2 = \frac{1*22*9}{2*7}[/tex]
[tex]A_2 = \frac{198}{14}[/tex]
[tex]A_2 = 14.143[/tex]
For the quarter circle
[tex]A_3 = \frac{1}{4}\pi r^2[/tex]
[tex]A_3 = \frac{1}{4} * \frac{22}{7} * 4^2[/tex]
[tex]A_3 = \frac{22}{7} * 4[/tex]
[tex]A_3 = \frac{88}{7}[/tex]
[tex]A_3 = 12.571[/tex]
Total area is:
[tex]Area = A_1 + A_2 + A_3[/tex]
[tex]Area = 15 + 14.143 + 12.571[/tex]
[tex]Area = 41.714[/tex][tex]m^2[/tex]
Is y=10-2/x a liner or nonlinear equation?
Answers
Answer:
Non-Linear
Step-by-step explanation:
In linear equations, the variable 'x' shouldn't be in the denominator of a fraction. It will not form a straight line when graphed.
See picture below.
Hope this helps!
y=10-2/x is a non linear equation
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.
The given equation is y=10-2/x
The x variable is in the denominator.
The given equation is not in the form of the linear equation y=mx+b.
and when we graph this equation we do not get a straight line.
Hence, y=10-2/x is a non linear equation

THREE NUMBERS BEHIND THE DECIMAL PT
Answers
Answer:
Step-by-step explanation:
4). This is an exponential function.
5). Let the equation of this function is,
f(x) = a(b)ˣ
Since, two points (-1, 4) and (0, 6) are lying on the graph of the function,
For (-1, 4),
4 = a(b)⁻¹
4 = [tex]\frac{a}{b}[/tex] --------(1)
For (0, 6),
6 = a(b)⁰
a = 6
From equation (1),
4 = [tex]\frac{6}{b}[/tex]
b = [tex]\frac{6}{4}[/tex] = 1.5
Therefore, equation of the function will be,
f(x) = 6(1.5)ˣ
6). Now the value of f(-4) will be,
f(-4) = 6(1.5)⁻⁴

LA
Maths
Answers
Answer:
x = 17
Step-by-step explanation:
Here, we want to find the value of x
mathematically, the mean is the sum of the numbers divided by the count of the numbers
The count of the numbers is 5
So we have;
(16 + 14 + x + 23 + 20)/5 = 18
73 + x = 5(18)
73 + x = 90
x = 90-73
x = 17
Akshay purchased goods costing ₹5,00,000 and sold at 20% profit on cost. Calculate the selling price of goods.
Answers
Answer:
the selling price of the goods is ₹6,00,000
Step-by-step explanation:
The computation of the selling price of the goods are shown below:
As we know that
Selling price = Cost price + profit
= 5,00,000 + 5,00,000 × 0.20
= 5,00,000 + 1,00,000
= ₹6,00,000
Hence, the selling price of the goods is ₹6,00,000
If x + y = 12 and x = 2y, then x=
Answers
The value of x is equal to 8.
Given the following equation;
[tex]x + y = 12[/tex] .....equation 1
[tex]x = 2y[/tex] .....equation 2
To find the value of x, we would solve the system of equations by using the substitution method to determine the value of y;
Substituting eqn 2 into eqn 1, we have;
[tex]2y + y = 12[/tex]
[tex]3y = 12\\\\y = \frac{12}{3}[/tex]
y = 4
Next, we would solve for the value of x;
From equation 2;
[tex]x = 2y\\\\x = 2(4)[/tex]
x = 8
Therefore, the value of x is equal to 8.

Eric can run 4 miles in 56 minutes. how many miles does Eric run if he runs for 42 minutes?
Answers
Answer:
3 miles
Step-by-step explanation:
y(x) = total minutes
y = total miles
x = the time in minutes it take erica to run a mile
4x = 56
x = 56/4
x = 14
so it takes her 14 minutes to run one mile
plug 14 into x
y(14) = 42
42/14 = 3 miles

Adult movie tickets cost $8 each. Children pay $5 for a ticket. For one movie, 90 total tickets were sold for a total of $525. Which system of equations can be used to find the number of each type of ticket, adult, a, and children, c, that were sold?
A. a + c = 90 8a + 5c = 525
B. a + c = 525 8a + 5c = 90
C. a + c = 90 5a + 8C = 525
D. a + c = 525 5a + 8C = 90
Answers
Answer: A
Step-by-step explanation:
I had this question on my test yesterday lol
The system of equation will be ". a + c = 90 8a + 5c = 525"
Let the number of adults tickets be represented by a
Let the number of children tickets be represented by c.
Since 90 total tickets were sold, this can be represented by the equation:
a + c = 90
Since adult movie tickets cost $8 each while the children pay $5 for a ticket, and total cost spent is $525, this will be:
8a + 5c = 525
Therefore, the correct option is A.
