Answer: Approximately 8.49 feet
==================================================
Explanation:
Draw a right triangle. The reference angle is between the ground and the kite string (aka hypotenuse). The hypotenuse is 12 and the side opposite the reference angle is x.
Refer to the diagram below.
We'll use the sine rule to find x
sin(angle) = opposite/hypotenuse
sin(45) = x/12
12*sin(45) = x
x = 12*sin(45)
x = 8.48528137423857
x = 8.49
This value is approximate.
Make sure your calculator is in degree mode.
I rounded to 2 decimal places, but feel free to round however you need if your teacher instructs otherwise.
Answer:
Area of the floor is 234 feet²
Step-by-step explanation:
To find the area of the floor of a rectangular storage room that is 2,106 cubic feet and has a height of 9 feet , we will follow the steps below;
First, write down the formula for calculating its volume
volume = l×b×h
but area=l×b
volume = area × h
From the question given volume = 2106 cubic feet
height h = 9 feet
volume = area × h
2106 = area × 9
Divide both-side of the equation by 9
2106/9 = area × 9/9
234 = area
area = 234 feet²
Area of the floor is 234 feet²
Answer:
He multiplied the radius by 2 instead of squaring it
Step-by-step explanation:
If 3ml of water = 1 part milk
12ml of water = x
3x=12
3x/3=12/3
Cancelling out by 3
x=4
Therefore she will need 4 part milk to make the recipe.
Answer:
0.007x, where x is the percentage of vinegar.
Step-by-step explanation:
x% of the mixture is vinegar, but the value of x is missing!
x% of 0.7 = 0.7x/100 = 0.007x
There are 0.007x liters of vinegar in the container.
