Answer:
1,000,000,000 leaves or 1 x 10^9 leaves
Step-by-step explanation:
One large oak tree has 2 x 10^5 leaves, so we can make that number to 200000
There are 5 x 10^3 oak trees in a forest, we can make that number to 5000
Since we want to find out how many leaves are in the whole forest we multiply: 200000 x 5000 = 1,000,000,000
So approximately there are 1 billion leaves or 1 x 10^9 leaves
Answer:
Ava needs to add 50ml of cleaner.
Step-by-step explanation:
Ratio of cleaner : water = 1:7
This means that the total ratio;(water+cleaner) = 1+7 = 8
Find fraction of each item out of the total ratio of 8;
Fraction of water = 
Fraction of cleaner = 
Knowing the fractions, find the quantity of cleaner in <em>ml </em>out of a total of 400-ml;
Cleaner = (1/8 )*400 = 50ml
Therefore, Ava needs to add 50ml of cleaner.
The third angle is 56 degrees because it is a right <u>triangle</u>, so the three angles will add up to 180 degrees. Since it is a right triangle, you know one angle is 90 degrees. All you have to do is add 90 and 34, and then subtract that from 180 to get your third angle.
