Answer:
is that all the context that is given?
Answer:
Step-by-step explanation:
From the given information, it will make a right triangle, in which hypotenuse = the length of the string = 100 feet
Let x denote the the height of the kite above the ground.
By trigonometry,

Hence, the height of the kite above the ground = 45.26 feet.
Since the hand is 3 feet above the ground height is ≅ 45
-1 1/4 as a decimal would be -1.25.
Since -1 is a whole number we would just write that as -1. 1/4 as a decimal is .25.
The answer is 40 cause 4 times 9 = 36 so juat add the 0 to 4 and it makes it 40 times 9 ='360
Looking at number 4, you first have to look at the information that you have:
On tuesday he practiced for 1 5/6 hrs
Monday he practiced for 7/10 hrs
He is supposed to practice for 1 1/4 hr.
You could write questions like:
How much more did Marco practice on Tuesday than he is supposed to practice?
This works because it does indeed involve subtraction, you would be subtracting the amount that he should have practiced from the amount of time that he did practice.
