1. You will have to find the height first which could be done by using pythagoras theorem
split the 12 by half giving 6
a^2 = b^2 + c^2
13^2 = 6^2+c^2
169 = 36+c^2
c^2=169-36
c^2=133
c=sqrt133
c= 11.53
area of triangle
1/2 x b x h
1/2 x 6 x 11.53
34.59
34.5(3 sf)
Answer:
the slope is 54
Step-by-step explanation:
The area of the triangle above will equal one half of a rectangle that is 5 units long and 3 units wide.
The area of the triangle is 7.5 units and the area of the rectangle is 15 units
Step-by-step explanation:
easy to look up : mili stands for 1/1000
so,
500 ml are 500/1000 liters.
25 ml are 25/1000 liters (a tiny glass).
and 1 Iiter is of course, 1000/1000 liters (1000 ml).
4 liters 500 ml are then
4×1000/1000 + 500/1000 = 4500/1000 l = 4500 ml.
how many glasses of 25 ml can be filled with that ?
this is the same question as into how many parts of 25 can 4500 be split ? or, how often does 25 fit into 4500 ?
all this is done by division :
4500 / 25 = 180
so, 180 of such glasses can be filled.
