If the elevation of Lake Superior is 186 feet above sea level and the elevation of the Caspian Sea is 17 feet below sea level, find the difference of the two elevations.
Answers
Answer:
203
Step-by-step explanation:
186+17= 203
(You add because the 17 is originally negative, therefore, the negative and subtraction sign cancel eachother out and cause the equation to become an addition problem. (edited)
The difference between the two elevations is 203.
What is the difference between the two numbers?
The difference between two numbers implies the actual distance between that two points in the number line.
How to calculate the difference between the two elevation?Here, the elevation of Lake Superior is 186 feet above the sea level, it can be treated as (+186)feet
and the elevation of Caspian Sea is 17 feet below of sea level, it can be treated as (-17)feet.
Now, the difference between two elevation of the lake is = 186-(-17)feet
=203 feet.

Answer:
136 Degrees
Step-by-step explanation
Set up as (3x+11) + (5x-9) = 90
then solve for x using algebra.
you can do this because angle NSO and RSQ are eqaul once you know x you will be able to solve all the other angles and subtract from 360 (the total angle) to find NSR.
Steps:
3x+11+5x-9 = 90
8x+2=90
x= 11
Solve 3(11)+11 = 44
add known angles:
44+90+90 = 224
360-224 = 136 degrees
We use concepts like complimentary angles and vertical angle theroem.

Luthan Company uses a plantwide predetermined overhead rate based on direct labor-hour. A cost formula that estimated $2,20,000 of total manufacturing overhead cost for an estimated activity level of 11,000 direct labor-hours. The company incurred actual total manufacturing overhead cost of $228,000 and 10,800 total direct labor-hours during the period. Determine the amount of manufacturing overhead cost that would have been applied to all jobs during the period.
Answers
Answer:
2,16,000
Step-by-step explanation:
Predetermined overhead rate is based on 11,000 direct labor hours.
The rate is 220,000/11,000 =20$
Since the actual activity is less than the standard labor hours, that is actual labor hours = 10,800
Thus, actual overheads to be applied based on predetermined rate shall be = Rate determined *actual hours
= $20*10,800 = $216000

It's not too difficult, but you can get wrapped around the axle. Here are the rules:
the opposite of a positive number is a negative numberthe opposite of a negative number is a positive numberThat is, turning a number to its opposite is just changing its sign.

If you layer these rules, you find ...

The first rule tells you the statement in parentheses is a negative number, and the second rule tell you its opposite is a positive number.
That is, a double opposite gets you back where you started. In short, any even number of minus signs cancel each other.

Now, let's create an equation to model the problem.
x * 0.273 = 125
Divide both sides by 0.273

Use your knowledge of the definitions of validity, soundness, strength, and cogency to determine which of the following statements are true.
a) To check an argument's deductive validity, you should first ask whether the argument is sound.
b) Some inductive arguments are neither cogent nor uncogent.
c) If a deductive argument has false premises and a false conclusion, then the argument could be valid.
d) All strong inductive arguments are equally strong.
e)An inductive argument cannot be both weak and uncogent.
f) If an argument is deductively valid and has premises that are all true, then the argument is cogent.
g) All deductive arguments are either completely valid or completely invalid.
h) To have a cogent inductive argument, the premises must not ignore a piece of evidence that would require a different conclusion.
i) If an argument is deductively valid, then at least one of its premises must actually be true.
j) A statement that is true is a sound statement.
k) No sound deductive arguments are invalid arguments.
l) If a deductive argument is unsound, the argument's premises cannot all be true.
m) If an inductive argument is strong, then the argument's conclusion must be true.
n) A weak inductive argument cannot be cogent.
o) In an invalid deductive argument, it is impossible for the premises to be true and the conclusion to be false simultaneously.
