Select one:
a. 209
b. 52.3
c. 188
d. 314
Answer:
(b) 52.3
Step-by-step explanation:
Given that,
Radius, r = 10
Angle, [tex]\theta=60^{\circ}[/tex]
We need to find the area of the sector. The formula for the area of the sector is given by :
[tex]A=\dfrac{\theta}{360}\pi r^2\\\\=\dfrac{60}{360}\times \dfrac{22}{7}\times (10)^2\\\\=52.3\ \text{unit}^2[/tex]
Hence, the correct option is (b).
A box has length 8 feet, width 4 feet, and height 3 inches. Find the volume of the box in cubic feet and in cubic inches.
The volume of a box in cubic inches = 13,824 cubic inches
The volume of a box in cubic feet = 8 cubic feet
What is the Volume of a box?The volume of a box = (length)(width)(height).
Give the following:
Length of the box = 8 feet
Width of the box = 4 feet
Height of the box = 3 inches
Convert the length and width to inches (1 foot = 12 inches)
Length of the box = 8 feet = (8)(12) = 96 inches
Width of the box = 4 feet = (4)(12) = 48 inches
Height of the box = 3 inches = 3/12 = 0.25 ft
The volume of a box in cubic inches = (96)(48)(3) = 13,824 cubic inches
The volume of a box in cubic feet = (8)(4)(0.25) = 8 cubic feet

The cost of taxi ride is 5 dollars plus 50 cents per mile write an algebraic expression that models the cost of taxi ride m miles
f(m) = 5 + 0.5m is the algebraic expression that models the cost of taxi ride.
Here, we are given that the cost of taxi ride is 5 dollars plus 50 cents per mile.
This means that-
the fixed cost = $5
variable cost = 50 cents per mile = $0.5 per mile
Let the number of miles travelled be m
then the variable cost will be = $0.5m
The total cost is given as-
total cost = fixed cost + variable cost
total cost = 5 + 0.5m
⇒ f(m) = 5 + 0.5m
here, m = miles travelled
and f(m) = total cost of the taxi ride
Hence, f(m) = 5 + 0.5m is the algebraic expression that models the cost of taxi ride.

Jennifer invests $7,000 in an account for 12 years that pays compound interest
annually. She uses the expression P(1 + r) to find the total value of the account.
What will be the total value of the account after 12 years if the interest rate is 1.6%?
Answer:
The rule is P(1+r%) power of time (T) so you're gonna apply the number to the rule
Step-by-step explanation:
P=7000
r=1.6%
T=12
7000 x (1+r%) power of T
(1+1.6%) power of 12 = 1.20983040
so when we calculate 7000 x (1+1.6%) power of 12
the answer will be = 8468.812846

The range of the graph is all real numbers greater than or equal to 0.
The domain of the graph is all real numbers greater than or equal to 0.
The range and domain of the graph are the same.
The domain of the graph is all real numbers.
Answer:
The domain of the graph is all real numbers.
Step-by-step explanation:
The equation that is set for this problem is y = |x+2| − 4. When finding the domain and range of this function, the domain and range is:
Domain: (−∞,∞), {x|x∈ℝ} ⇒ (The domain (x-values) is all real numbers
Range: [−4,∞), {y|y≥−4} ⇒ (The range (y-values) need to be greater than or equal to −4)

What are the two equations to set up to solve the equation |2x−3|=11
The two equations to set up to solve |2x−3|=11 are 2x − 3 = 11 and 2x − 3 = -11
Hence, option C)2x − 3 = 11 and 2x − 3 = -11 is the correct answer.
What are the two equations to set up to solve the equation |2x−3|=11?Given the equation in the question;
| 2x − 3 | = 11
To solve the equation, we have to remove the absolute value term and this will create the a ± on the right side of the equation.
Note that; |x| = ±x
Hence;
| 2x − 3 | = 11
2x − 3 = ±11
The solution of the equation is the result of both the positive and negative portions of the of the solution.
2x − 3 = 11 and 2x − 3 = -11
Therefore, the two equations to set up to solve |2x−3|=11 are 2x − 3 = 11 and 2x − 3 = -11

What is the midpoint?The mid point of the line is defined as the center point of any line it means that the distance of this point is same from the one end and to the other end.
Given that:-
The midpoint between two points is (-16 12). of one endpoint is (-24 8) then the other is (-8,The formula for calculating the midpoint of the line for the y coordinate will be:-
Ym= ( y1 + y2 ) / 2

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 ,
Total number of members in the relay team = 3 members
Total distance covered by the 3 members of the relay team = 3/8 miles
Now the equation will be ,
The distance ran by each member of the team =
Total distance covered by the 3 members of the relay team / Total number of members in the relay team
So , The distance ran by each member of the team = ( 3/8 ) / 3
= 3/8 x 1/3
= 1/8 miles
Therefore , the distance ran by each member of the team is 1/8 miles
And , taking the sum of each person's distance , we get
1/8 + 1/8 + 1/8 = 3/8
which is the total distance covered by the 3 members
Hence , The distance ran by each person in the relay team is 1/8 miles
