Hope this helps!!!!!!!
Answer:
270 cm^2
Step-by-step explanation:
This is quite easy.
There is formula for it, the formula is bh/2
b= is the base or side that the triangle's altitude or height is perpendicular to.
h= is the height of the triangle or the altitude of the triangle.
I can always like to thing that a triangle is like half of a rectangle because the area for a rectangle is bh, but in a triangle it is half the bh.
b= 30
h=18
Now substitute the values in the formula
30(18)/2
30 times 18 = 540
divide the product by 2
540/2 = 270
Answer:
4 eggs are left.
Step-by-step explanation:
It is actually a tricky question and the trick is that the person, who initially have 6 eggs, has broken two eggs out of them.
Those two broken eggs were then fried and later he ate those.
It is a single incident but in question it appears that 3 different incidents took place in which the person have used all 6.
So actually, he only ate 2 eggs out of 6.
Answer:
n(A) = 6
Step-by-step explanation:
Let consider a set A = {a, m, b, d, h}. There are five elements in the set. The no of elements in a set is known its cardinality. Since set A has five elements, its cardinality number is 5. The cardinality of the set A is denoted by n(A).
Hence, from the given information:
The set A = {1, 2, 3, 4, 0, 7} have a cardinality number of 6
n(A) = 6
1. Take an arbitrary point that lies on the first line y=3x+10. Let x=0, then y=10 and point has coordinates (0,10).
2. Use formula 
to find the distance from point 
to the line Ax+By+C=0.
The second line has equation y=3x-20, that is 3x-y-20=0. By the previous formula the distance from the point (0,10) to the line 3x-y-20=0 is:
.
3. Since lines y=3x+10 and y=3x-20 are parallel, then the distance between these lines are the same as the distance from an arbitrary point from the first line to the second line.
Answer:
