Answer:
should be 80, angle 50 is congruent on both sides to 50+50 equals 100. The triangle sum theorem says a triangle adds up to 180 degrees so we are left with 80, X=80 degrees
50 + 50 + x = 180
thus , x = 80

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.)
Answers
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 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.
Answers
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

Daniel can spend no more than $40 at the fair. If admission into the fair is $10 and the rides cost $1.50 each, which inequality represents the greatest number of rides Daniel can go on?
A. 10r + 1.50 ≥ 40
B. 1.50r + 10 ≤ 40
C. 1.50r + 10 <40
D 10r+1.50<40
Explain your reasoning and solve the inequality :
Answers
Answer:
B
Step-by-step explanation:
The sum spent has to be either equal to or less than 40. So r many rides, each of them being 1.50, plus 10 dollars has to equal to less or equal to 40 dollars.
Answer:
The answer is B
The greatest number of rides Daniel can go on is 20.
Step-by-step explanation:
Total: The same or less than 40
Fair Admission: 10
ride: 1.50x
40 ≤ 10 + 1.5r
To solve:
40 ≤ 10 + 1.5r
40 - 10 ≤ 10 + 1.5r - 10
30 ≤ 1.5r
30 ÷ 1.5 ≤ 1.5r ÷ 1.5
20 ≤ r
The greatest number of rides Daniel can go on is 20.

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?
Answers
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.
Answers
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
