Answer:
5cmStep-by-step explanation:
From the questions;
1cm represents 200km on the map
If the length of distance between the cities is 1000km, the distnce on the map will be say x;
x cm = 1000 km
Divide both equations;
1/x = 200/1000
Cross multiply;
200x = 1 * 1000
200x = 1000
x = 1000/2000
x = 5cm
Hence the length on the map that represents the distance between the two cities is 5cm
Find the area of a 60 degree sector with radius 10.
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 certain computer can perform 105 calculations per second. How many calculations can it perform in 10
seconds? Write your final answer in exponential form.
The number of calculations that a computer can perform in 10 seconds is 1050.
The exponential form of 1050 is 1.05 × 10³
Given,
The number of calculations that a computer can perform per second = 105
We have to find the number of calculations can it perform in 10 seconds.
That is,
Number calculations in 10 seconds = Number of calculations per second × 10
Number of calculations in 10 seconds = 105 × 10
Number of calculations in 10 seconds = 1050
That is, the number of calculations that a computer can perform in 10 seconds is 1050.
The exponential form of 1050 is 1.05 × 10³

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

Find m< RQS . How can do I solve this
Step-by-step explanation:
6x° = (2x + 3)° + 77° (Exterior angle of a triangle = sum of two interior angle )
6x = 2x + 3 +77
subtract 2x from both sides
6x - 2x = 2x - 2x + 3 + 77
4x = 3 + 77
4x = 80
therefore:
x = 20°
angle PQR = 120°
angle RSQ = 43 i.e [(2 x 20) + 3)]

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

Given the line
[tex]y=-x+2[/tex]
We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
here
m is the slope and b is the intercept
Thus, the slope = -1
We know that the parallel lines have the same. Thus, the slope of the parallel line is: -1
Using point-slope of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = -1 and the point (4, 0)
[tex]y-0 = -1 (x-4)[/tex]
Writing in the slope-intercept form
[tex]y = -x+4[/tex]
Thus, the slope-intercept form of the equation of the line equation parallel to y=-x+ 2 will be:
[tex]y = -x+4[/tex]8)
Note: Your line is a little bit unclear. But, I am assuming the

Given the assumed line
y = -x-1
We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
here
m is the slope and b is the intercept
Thus, the slope = m = -1
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = -1
perpendicular slope = – 1/m = -1/-1 = 1
Using point-slope of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = 1 and the point (4, 3)
[tex]y - 3 = 1 (x-4)[/tex]

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

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)
