Answer:
if it is a right angle triangle then;
step 1 Determine if hypotenuse or side
step 2 calculate a^2+b^2 = c^2 or c^2-b^2 = a^2 if not given hypotenuse.
if it is an obtuse or scalene triangle then
step 1. Determine the triangle third length we use trigonometry as cos (side a/sideb) to determines the angle between a and b.
With such angle for opposite side we can use sin (angle) x side to find hypotenuse or sin(angle) x hypotenuse to find side.

Reduce 40/100 please helppp
Answer:
2/5
Step-by-step explanation:
40 and 100 can both be divided by 20. 40 divided by 20 equals 2 and 100 divided by 20 equals 5
Answer:
2/5 (0.4)
Step-by-step explanation:
We can reduce this by first looking at the fraction. [tex]\frac{40}{100}[/tex]
We can first divide by 10 on both sides to get a better number: [tex]\frac{4}{10}[/tex]
We can simplify both by 2 since thats another common number: [tex]\frac{2}{5}[/tex]
That is the most we can go to!

HI PLEASE ANSWER BEFORE 12:00a.m. EST
Answer:
D
Step-by-step explanation:
Amanda's unit rate would be
s=50m
while Mary's is
s=60m
60-50 is 10, meaning the answer would be D.
Mary saves $10 more than Amanda every month.
Hope this helps! :)
Hi there!
We can find an equation that models Amanda's savings using the equation:
y = km, where:
k = rise / run (Amount/months)
Plug in a set of values from the table:
k = 100/2 = 50
y = 50m
We know that Mary saves y = 60m dollars a month, so we can determine the correct comparison by plugging in a value of 1 month into both equations:
Amanda:
y = 50(1) = $50
Mary:
y = 60(1) = $60
The difference between Mary's and Amanda's savings is $60 - $50 = $10, so each month, Mary saves $10 more than Amanda.
The correct answer is D.

2/3 is your answer
Step-by-step explanation:
Hope this helps
P.S.(from k12)
The slope of the line is 2/3.
Here,
Graph of a line on coordinate plane. Axes are labeled x and y.
Three points are with ordered pairs (2, 3), (5, 5), and (8, 7) and the line passes through these three points.
We have to find the slope of the line.
What is the slope of the line?
Let two points (x₁, y₁) and (x₂, y₂) are on the line, then slope of the line is calculated as;
[tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
Now,
Three points are passes through the line are (2, 3), (5, 5), and (8, 7).
To find the slope, Let any two point from three given points.
Let (2, 3) and (5, 5) on the line.
Hence, Slope is calculated as,
⇒ [tex]m = \frac{5-3}{5-2} = \frac{2}{3}[/tex]
Therefore, The slope of the line is 2/3.
