Step-by-step explanation:
it’s adding a number by itself the same as multiplying it by 2
Answer:
83.35 feet above ground.
Step-by-step explanation:
Please find the attachment.
We have been given that Hudson (3 feet tall) is on the beach flying a kite. His angle of elevation looking up to the kite is 40 degrees. The kite string is 125 ft long.
We can see that the string of kite forms a right triangle with an angle of elevation (40 degrees) as shown in the attachment.
To solve for h, we will use sine as sine related opposite side of a right triangle with hypotenuse.
To find the height of kite off the ground, we will add height of Hudson to 80.35 feet as well as he is flying the kite.
Therefore, the kite is approximately 83.35 feet above ground.
The weight of one foot of the steel pipe is 1.24 pounds or more accurately, 1.239905.... pounds.
This type of problem is solved using cross multiplication. You know the length (16.84 feet), and the weight (20.88 pounds), of the steel pipe. But what you do not know is the weight of one foot of the steel pipe. Since that is what we are solving for, the weight of one foot of the steel pipe will be our x variable.
This is how I set it up...
16.84 1
——— * ———
20.88 x
I came up with this equation. The length of the pipes I put in the numerator (top), and the weight I put in the denominator (bottom). Since 16.84 feet of a steel pipe weighs 20.88 pounds, 1 foot of a steel pipe weighs x pounds. After you have the equation set up you then move on to cross multiplication.
Step 1: Multiply the top number of the first fraction by the bottom number of the second fraction.
16.84*x= 16.84x
Step 2: Multiply the bottom number of the first fraction by the top number of the second fraction.
20.88*1=20.88
Step 3: Set the answers from step 1 and step 2 equal to each other.
16.84x=20.88
Step 4: Divide 16.88 on both sides so x is by itself.
16.84x 20.88
——— = ———
16.84 16.84
And after you divide on each side you have your answer which should be x=1.24
