Most of Mauna Kea, a volcano on Hawaii, lies below sea level. If this volcano begins at 5998 meters below sea level and then rises 10,203 meters, find the height of the volcano above sea level.
Answers
Final answer:
Height of volcano above sea level is 4205m.
Step-by-step explanation:
Step 1
Height of volcano below sea level: 5998m
Step 2
Total height of volcano below and above sea level:
10203m
Step 3
Subtract height of volcano below sea level from total height of volcano to get height of volcano above sea level:
10203 - 5998
Step 4
Subtract the terms:
10203 - 5998 = 4205

If it cost $6 to fill a gas tank in 1970, how much would it have cost to fill the same tank in 2010?
Answers
Step-by-step explanation:
Well since it cost 6$ and the price was 0.36 you can calculate how many gallons you needed to fill up your tank which is calculated by dividing the price to fill the gas tank by the price per gallon
6/0.36 = 16.667 gallons
Now multiply the amount of gallons you need to fill your gas tank by the price in 2010
16.667 * 2.84 = 47.36
You could also just look at the price as a percentage relative to 1970 prices and see that the price increased by 788.9% and the find what 788.9% is of 6$. Which can be done by dividing 788.9 by 100 to convert it into decimal form which gives you 7.889 and then multiply that by the original price of 6$ to fill your gallon to get 47.33 which is slightly different although this is likely due to rounding.

What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The first table represents a linear function because the slope remains constant through out the function

A garden table and a bench cost 735 combined. The garden table costs 35 more than the bench. What is the cost of the bench?
Answers
Answer:
350
Step-by-step explanation:
Let,
x = bench
x + 35 = garden table
EQUATION:
(x) + (x + 35) = 735
2x = 735 - 35
2x = 700
x = 350
SUBSTITUTE:
bench costs 350 and garden table costs 385
Hello!
Based on the info we have we can form 2 equations :
(Keep in mind x is the cost of the garden table and y is that of the bench)
x + y = 735x = y + 35Now substitute x in the first equation.
⇒ y + 35 + y = 735

The terminal side of angle θ intersects the unit circle in the first quadrant at (16/19,y). What are the exact values of sinθ and cosθ?
Answers
The exact value of sin θ and cos θ is: sinθ =(√105)/19 and cosθ =16/19
The terminal side of an angle is the angle at the standard position. The terminal side of an angle θ drawn in angle standard position is the side which isn't the initial side.
Given that the point of intersection of the terminal side of θ an the unit circle is:
(16/19,y)
The exact value of sin θ and cos θ is: sinθ =(√105)/19 and cosθ =16/19
The given parameters is represented by:
(16/19,y)
This means that :
(cosθ ,sinθ )=(16/19,y)
Using the following trigonometric identity:
cos²θ +sinθ =1
We have:
(16/19)²+y²=1
Expand fraction:
(256/361)+y²=1
Collect like terms:
y²=1-(256/361)
Take LCM:
y²=(361-256)/361
y²=105/361
Take square roots
y=(√105)/19
Substitute value for y in
(cosθ ,sinθ )=(16/19,y)
By comparison:
cosθ =16/19
sinθ =(√105)/19
So the exact value of sin θ and cos θ is: sinθ =(√105)/19 and cosθ =16/19
