Identify the angle pair from the diagram above: <2 and <7
Answer:
2 and 7 are alternate exterior anglesStep-by-step explanation:
Alternate exterior angles are angles that are on different sides of the transversal and on the outside of the parallel lines. There is a theorem that says that alternate exterior angles are congruent if two parallel lines are cut by a transversal.

How do you solve for X?
Answer:
<L+<M+<N=180
<NLM and <XLN are supplementary meaning their angle measure add to 180.
therefore,44+46+L=180
90+L=180
l=90
If l=90 then the <NLX is also 90 since they are supplementary angles
therefore, 3x+42=90
3x=48
x=16

A circle is graphed on a coordinate grid. Its center is at (3, 4), and the circle passes through point (3, 1). What is the approximate area, in square units, of the circle? (Use 3.14 for π.)
Answer:
it is either 18.84 or 31.40
Step-by-step explanation:
just do it in your head
The area of the circle is 28.26 square units
The center of the circle is given as:
[tex](a,b) = (3,4)[/tex]The circle passes through the following point
[tex](x,y) = (3,1)[/tex]Start by calculating the radius using the following distance formula
[tex]r = \sqrt{(x -a)^2 + (y - b)^2}[/tex]
So, we have:
[tex]r = \sqrt{(3 -3)^2 + (4 - 1)^2}[/tex]
[tex]r = \sqrt{9}[/tex]
Square both sides
[tex]r^2 = 9[/tex]
The area of the circle is then calculated as:
[tex]Area = \pi r^2[/tex]So, we have:
[tex]Area = 3.14 \times 9[/tex]
[tex]Area = 28.26[/tex]
Hence, the area of the circle is 28.26 square units

a college spends 40% of an individual's tuition on salaries and the remainder on other costs if they spend 1,800 on other costs how much is an individual's tuition?
Answer:
$3000
Step-by-step explanation:
If the remainder is spent on other costs, then that means 60% of the tuition as spent on other costs.
To find the total tuition, divide 1800 by 0.6:
1800/0.6
= 3000
So, their tuition was $3000
The cost for an order of 100 kilograms of steel bars is $230. The cost for an order of 150 kilograms of steel bars is $320. Write an equation for the cost of an order of steel bars (y) in terms of the weight of steel bars ordered (x). Show or explain how you found your equation.
Answer:
y = 9x/5 + 50
Step-by-step explanation:
We are represent the information as coordinate (x,y)
If the cost for an order of 100 kilograms of steel bars is $230, this is expressed as (100, 230)
Also if the cost for an order of 150 kilograms of steel bars is $320, this is expressed as;
(150, 320)
Find the equation of a line passing through the points. The standard form of the equation is expressed as y = mx+c
m is the slope
c is the intercept
Get the slope;
m = y2-y1/x2-x1
m = 320-230/150-100
m = 90/50
m = 9/5
Get the y-intercept by substituting m = 9/5 and any point say (100, 230) into the expression y = mx+c
230 = 9/5(100)+c
230 = 9(20)+c
230 = 180 + c
c = 230-180
c = 50
Get the required equation
y = mx+c
y = 9/5 x + 50
Hence an equation for the cost of an order of steel bars (y) in terms of the weight of steel bars ordered (x) is y = 9x/5 + 50

A car is traveling at a constant speed of 55 miles per hour. Using m for miles and t for time, write 2 equations to represent this situation. One equation to solve for miles and the other equation to solve for hours.
Answer:
m = 55t
t = m/55
Step-by-step explanation:
According to the formula for calculating speed expressed as;
Speed = distance/time
Given;
Distance = 55mph
required:
distance as a function of t
time as a function of distance m
If distance is m and time is t
From the formula;
55 = m/t
m = 55t
Hence the equation to solve for miles m is m = 55t
To get t, we will cross multiply from 55 = m/t;
55t = m
Divide both sides by 55
55t/55 = m/55
t = m/55
Hence the equation to solve for time in hours is t = m/55
