Step-by-step explanation:
Answer:
A trick I did when it comes to multiplying by 10, is just add a 0 at the end of the number your multiplying. Try for yourself!
Answer:
When sides are doubled, the area of new triangle will always be 4 times the original, the change in area will be 3 times. Hence the % change will always be 300% irrespective of the type of triangle.
Step-by-step explanation:
For the first question, all you need to know is that the (amount you want) divided by (the amount of cards total) is the probability of getting the amount you want at random. for example, if there are 3 red marbles in a bag of ten marbles, you divide 3 by 10 (0.30) the probability of picking up a red marble is 30%. try adding up how many cards you want to pick up by the number of cards total.
The height of the given trapezoid is 7.5 m.
Step-by-step explanation:
Step 1:
The trapezoid's area is calculated by averaging the base lengths and multiplying it with the trapezoid's height.
The trapezoid's area, 
Here 
is the lower base length and 
is the upper base length while h is the height.
Step 2:
In the given problem, 
and 
. Assume the height is h m.
The trapezoid's area 
So the height of the given trapezoid is 7.5 m.
