These numbers are "a" and "b".
Sum is 64, so
a+b=64
Difference is 42 so
a-b=42
So you've got:
When a+b=64 and a=53 you've got:
53+b=64
b=11
So these numbers is 53 and 11.
Answer:
I use faction
Step-by-step explanation:
The first boat.
÷ 10 =
÷ 2 =
The first boat move
The second one do the same
÷ 10 =
÷ 2 =
That is the speed of each boat.
The first boat need 50 minutes to get to the other side
2000 ÷ 2 =1000
1000 x 3 = 3000
3000 ÷ 60 = 50
The second boat need 66.6666666667 minutes to get to the other side
200 ÷1.5 = 1333.33333333
1333.33333333 x 3 = 4000
4000 ÷ 60 = 66.6666666667
Answer:
Step-by-step explanation:
Part A:
Area = (8*6 sin 76) / 2
Area = 23.287 (use the first Choice)
Part B:
You are told 1 hay =1 square meter and cost 5.49 dollars
so you need 23.287 hays but since only full hays, you need 24 to cover the whole pen
Amount = 24*5.49 =131.76
Answer: 72.9
Step-by-step explanation:
first thing is to find sin, cos and tan.
opposite the right angle is hypotenuse, in line with the angle is opposite and finally in-between both angles is adjacent.
then you will have o/a which is tan.
then in your calculator type tan^-1(13/4)=72.9
hope this is what you are after.
