You make a right triangle, an isosceles, and a scalene. You can't make an equilateral, because those sidelengths are not the same size.
Answer:
Step-by-step explanation:
make the other half of the triangle on top one and then you make another triangle out of the bottom one and make the other half so you just want to put a line from one line on the right side to the bottom line so then you just need do the same thing on the left side
One year, the population of a city was 397,000. Several years later it was 412,880.
Find the percent increase.
The percentage increase from the initial population of 397,000 to 412,880 is 4%
How to determine the percentage increase?From the question, we have the following numbers:
397,000 and 412,880.
The numbers are increments from 397,000 to 412,880.
The percentage increase is calculated as:
%Percentage = (Old number - New number)/Old Number
Substitute the numbers in the above equation
%Percentage = (412880 - 397000)/397000
Evaluate the difference
%Percentage = 15880/397000
Evaluate the quotient
%Percentage = 0.04
Express 0.04 as percentage
%Percentage = 4%
Hence, the percentage increase from the initial population of 397,000 to 412,880 is 4%

The diagram is not drawn accurately.
Answer: 23 cm
Step-by-step explanation:
Given
[tex]a=3.5\ cm\\b=9.4\ cm[/tex]
Triangle in the figure is right-angled triangle. Therefore, Pythagoras theorem can be applied. Suppose the unknow length of the triangle is x
[tex]\Rightarrow x^2=a^2+b^2\\\Rightarrow x^2=3.5^2+9.4^2\\\Rightarrow x^2=12.25+88.36\\\Rightarrow x^2=100.61\\\Rightarrow x=10.03\ cm[/tex]
The perimeter of triangle is the sum of the lengths of sides.
[tex]\text{Perimeter }P=3.5+9.4+10.03\\\Rightarrow P=22.93\ cm\approx 23\ cm[/tex]

The freezing point of neon is about -249c . The freezing point of chorine is about 148c higher. What is the approximate freezing point of chlorine?
Answer:
-101 c.
Step-by-step explanation:
-249 + 148
= -(249 - 148)
= -101 C.
The approximate freezing point of chlorine is -101°C.
We have,
The freezing point of neon is about -249c .
The freezing point of chorine is about 148c higher.
To find the approximate freezing point of chlorine, we add 148°C to the freezing point of neon:
= -249°C + 148°C
= -101°C
Therefore, the approximate freezing point of chlorine is -101°C.

Answer: 38/9

The equation of the line that goes through the points ( − 3 , − 9 ) and ( − 6 , − 3 ) can be written in the form y = m x + b
Answer:
[tex]y=-2x-15[/tex]
Step-by-step explanation:
[tex]y=mx+b[/tex].
m is the slope of the line. To find it we can do [tex]\frac{dy}{dx}[/tex] which is the difference between the y-coordinates divided by the difference between the x-coordinates.
So: [tex]\frac{dy}{dx} =\frac{-9-(-3)}{-3-(-6)} =\frac{-6}{3} =-2[/tex]. Now we have the slope, let's input a set of coordinates into the equation so that we can find the constant [tex]b[/tex].
[tex]-9=-2(-3)+b[/tex]
[tex]b=-15[/tex] - Re-arranging to get b
Now re-write the equation as we have the constants.
[tex]y=-2x-15[/tex]
