Answer:
0.0649350649350649
Step-by-step explanation:
Red to yellow.......7:3....added = 10
so 7/10 of the total students wore red and 3/10 of the total students wore yellow
and there are 300 total students...
7/10(300) = 2100/10 = 210 wore red
3/10(300) = 900/10 = 90 wore yellow
how many more wore red.....(210 - 90) = 120 more students wore red then yellow
Answer:
2 and a half @ 2.5 inches (sorry i can't type the fraction)
Step-by-step explanation:
- english is my second language so sorry if you doesn't understand:
(1/2, 1/4)=(x,y)
based on the graph shown that each grid on the y axis represents 1/4, that is the smallest scale stood in the y axis.
this means 2 grid= 1/4 x 2 = 1/2 @ 0.5 inches.
since the '5 months-hair-length' is above about 2 grid above 2 inch:
2 inch + 0.5 inch= 2.5 inch
Answer:
Isosceles
Step-by-step explanation:
In order to figure what type of triangle this is out, we need to start by plotting the given points. That will help us visualize the triangle better and see if our conclusions make sense. (See attached picture).
Once we got the triangle, the strategy to follow is to use the distance between two points formula to see what the measurement of each side of the triangle is. This will help us determine if 2, 3 or none of the sides of the tirangle are the same.
The distance formula is the following:

so now we can find the desired distances, let's start with the distance between P and Q:

which yields:

next, let's find the distance between P and R:

which yields:

and finally the distance between Q and R:

which yields:

As you may see from the result, only two of the three sides are the same, |PQ| and |PR|, so this will be an Isosceles triangle.
