A table saw is on clearance for 20% off. If the sale price of the table saw is $380, what was the original price? Justify your solution. Round to the nearest cent if necessary.
20% off means it is selling for 80% of the original price ( 100% - 20% =80%)
Divide the sale price by 80% as a decimal:
380/0.80 = 475
The original price was $475
Justify:
Multiply the original price by 20% and subtract:
475 x 0.20 = 95
475-95 = $380 which is the sale price.
Answer:

Help me classify the triangles by its sides and measuring its angles :)
Answer:
Triangle 1: Isosceles obtuse
Triangle 2: Right scalene
Step-by-step explanation:
Isosceles triangles have two congruent sides and two congruent angles. Triangle one fits this description because the double markers on sides AC and AB indicate that the two sides are congruent.
Obtuse triangles have an angle that is larger than 90 degrees. Triangle one fits this description as indicated by angle A. If it were a right angle, it would have a square symbol (as shown in triangle 2). The other two angles are obviously smaller, and they would be acute angles.
Right triangles have an angle that is exactly 90 degrees. Right triangles will have a square to indicate that it has this measurement.
Scalene triangles have three different measurements for its sides and its angles.

I need help please
Answer:
After solving the given formula for l, we get
l = A/w
Step-by-step explanation:
Given formula is:
A = lw
The given formula is the formula for area of a rectangle.
Solving for a particular variable means that the variable has to be isolated on one side of the equation.
In order to solve,
Dividing both sides by w
[tex]\frac{A}{w} = \frac{lw}{w}\\l = \frac{A}{w}[/tex]
Hence,
After solving the given formula for l, we get
l = A/w

Answer:
2160 degrees
Step-by-step explanation:
The asnwer would be 2160, as the 14 sided polygon would have 10 obtuse angles and 4 acute angles, meaning that it can only be 2160.
-9 less than or equal to -6 add 15 to both sides

Planes A and B are shown.
If a new line, p, is drawn parallel to line I, which
statement is true?
n
VI A
Line p must be drawn in plane B.
O Line p must be perpendicular to line m.
Line p must be drawn so that it can lie in the same
plane as linel.
O Line p must be drawn in the same plane as line n.
m
Answer: C: Line p must be drawn so that it can lie in the same plane as line l
Step-by-step explanation: edge 2020
Line p must be drawn so that it can lie in the same plane as line l.
Option C is correct.
What is Coordinate Geometry?One of the most intriguing ideas in mathematics is called coordinate geometry. By using graphs with curves and lines, coordinate geometry (also known as the analytic geometry) explains how geometry and algebra are related.
As per the given data:
A new line, p, is drawn parallel to line I.
We have to find that which of the statements from the given options in the question are true.
It was discovered that the specified set of lines consisted of plane A having line m and plane B having line n. Lines m and n are orthogonal to one another.
The new line l has been created parallel to line p in accordance with the planes. It has been possible for line p to cross the plane B. Line l has therefore also been intersecting plane B.
The line p has been drawn such that it is on the same plane as the line l since a line cannot cross its own plane. Option C is right as a result.
Hence, Line p must be drawn so that it can lie in the same plane as line l.

At her restaurant, Violet opened 285 cans of tomato sauce. She needs to use 4 cans of sauce for one pan of lasagna. How many pans of lasagna could Violet make if she uses all of the cans? Write the answer as a mixed number.
Answer:
71 1/4 pans of lasagna
Step-by-step explanation:
From the above question:.
4 cans of tomato sauce = 1 pan of lasagna
285 cans of tomato sauce = x
Cross Multiply
4x = 285 × 1
x = 285/4
x = 71 1/4 pans of lasagna
Violet could make 71 1/4 pans of lasagna

Find the slope of the line.
Answer:
C
Step-by-step explanation:
Well You can tell right away its a positive line since its rising from left to right so the answer has to be positive
If the slope were to be 4 the line would be a Little more titleted becuasea slope of 4 is going up 4 and going tot he right 1.
ANd you can’t heck from any given point and just try all the positivw possibilties.
Or you can just use rise over run, start form a point, rise which means go up until you reach the second layer of the line and just run (go To The right) until you hit a point.
You’ll get 1/4

There are 159 students to be grouped in math teams. Each team is to have the same number of students. Can each team have 3, 4, 5 or 6 students?
Answer:
3 students for each team
Step-by-step explanation:
Answer:
Each team can have 3 students.
Step-by-step explanation:
159 students grouped in three's = 159/3=53
The same thing goes for if they were grouped in 4's, 5's, or 6's.
159/4=39.75 159/5=31.8 159/6=26.5
And since you cant divide single students into splits objects, 3 is
the only solution that works.
Hope this helps. :)
Miranda is selling ice cream at the park to help raise money for the animal shelter. The amount of money she raises for the shelter (y) is proportional to the number of ice cream cones (x) she sells. If Miranda wants to raise $250 for the shelter, how many ice cream cones would she need to sell?
Answer:
The question is lacking the detail of the price of the ice cream cones.
Assuming the ice cream cones cost $2 each then she would have to sell;
= 250/2
= 125 ice cream cones
If she sells 125 ice cream cones, she will be able to raise $250 if the cones are sold at $2 each.

A bird traveled a horizontal distance of 300ft over a distance that rose 150ft what is the angle of elevation that the bird made with the ground . Round to the nearest tenth
Answer:
26.56 degrees
Step-by-step explanation:
The set up will give a right angles triangle
Given
The Horizontal distance = Adjacent side = 300ft
The height = Opposite side = 150ft
Using the SOH CAH TOA identity;
tan theta = opposite/adjacent
tan theta = 150/300
tan theta = 1/2
theta = arctan 1/2
theta = 26.56 degrees
Hence the angle of elevation is 26.56 degrees
