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
The spinner is divided into 10 equal parts. Since only one part is labeled 3, the answer is 1/10.
If he once traveled 36 hours and he takes 6 hour trips you do
10x3=30 so every six hours he takes 30 minute brakes then 36 divided by 6 equlas 6 you would do 30x6= the answer!!! (Btw i do 6th grade math)
Answer:
yes he is correct. he spent 125% more time
Step-by-step explanation:
his original time spent was 20 hours
he spent a new time which is 25 hours
increased time = 25- 20 = 5 hours
% increase = increase/ original ×100%
%increase = 5/ 20 ×100%
= 1/4 ×100%
= 25%
total increment = 100 + 25 =125%
