Answer: 34.64 m
Step-by-step explanation:
Given: A boat is 60 m from the base of a lighthouse.
The angle of depression between the lighthouse and the boat is 37°.
By using trigonometric ratios :

here x= 37°, side opposite to x = height of lighthouse (h) , side adjacent to x = 60 m

Hence, the lighthouse is 34.64 m tall.

The answer is the option A
9.9 grams
because the balance is accurate to the nearest 1/10 gram; thus, the <span>highest level of accuracy appropriate to the limitations of the balance is 0.10 gram (1/10)</span>
Hello!
This expression can be broken down into 3 separate parts:
1. "the quotient of a number and (-7)"
2. "decreased by 2"
3. "is 10"
We'll begin with the first part. The word "quotient" implies the result of a
division problem. Therefore, this part can be represented by the following expression (let "x" represent the unknown number):

Now we'll move on to the second part. If something is decreased by a value of 2, we know that 2 is being
subtracted. Therefore, this part can be represented by the following expression:
– 2
Now we'll move on to the third and final part. The phrase "is 10" implies that the operations preceding this part are
equal to 10. Therefore, this part can be represented by the following expression:
= 10
Finally, put the three parts together to create the following equation:

– 2 = 10
The equation has now been fully translated. If, however, you are required to find the unknown value (x), begin by adding 2 to both sides of the equation:

= 12
Now multiply both sides by (-7):
x = (-84)
We have now proven that
the unknown number is equal to (-84).I hope this helps!
Answer: 6.35444444×10^13 gallons
Step-by-step explanation:
So a dishwasher uses 444 gallons of water per load.
That means it'll use 444*215215215 = 95555555460 gallons of water for 215215215 loads
Since washing dishes by hand takes 666 as much as water in comparison to using a dishwasher, we can do 95555555460x666 to find that you need 6.36399999×10^13 gallons of water to wash 215215215 loads.
The question asks for how much more water in gallons you can save, so do 6.36399999×10^13 - 95555555460 to get 6.35444444×10^13 gallons
