<u>Answer:</u>
Given below.
<u>Explanation:</u>
Coordinates given: W( -4, -3 ) , X( 1 , -2 ), Y(2, -7 ) , Z( -3, -8)
To find the distance we will use the formula: distance=√((x2-x1)²+(y2-y1)²)
WX = √((1--4)²+(-2--3)²)
= √26
YZ = √((-3-2)²+(-8--7)²)
= √26
XY = √((2-1)²+(-7--2)²)
= √26
WZ = √(-3--4)²+(-8--3)²
= √26
WY = √(2--4)²+(-7--3)²
= 2√13
XZ = √(-3-1)²+(-8--2)²
= 2√13
Given:
A deep sea diver started at sea level (0 feet).
Rate of diving = 5.6 feet per minute.
Time =
hour
To find:
The rational number that represents his position relative to sea level.
Solution:
We know that,
1 hour = 60 minutes
hour = 30 minutes
A deep sea diver, dove at a rate of 5.6 feet per minute.
Distance covered in 1 minute = 5.6 feet
Distance covered in 30 minute = 30 × 5.6 feet
= 168 feet
The diver dove 168 feet in
hour. Since it is below the sea level, therefore it should be negative.
So, the rational number that represents his position relative to sea level is
feet.
Therefore, the correct option is D.
132.40 should be the answer
Step-by-step explanation:
So when a question asks what is x% of the y number. It's asking you to convert the x into decimal form by dividing by 100 and then multiply it by y. This gives you the equation:
which gives you x% of y. so 15% of 43 is
. 43% of 300 is
.
the 12% of what number is 43 is a bit more tricky. It's asking you to instead find a number in which 12% of it is equal to 43. So instead of plugging solving for the percentage (which is already given) you solve for y. This gives you the following equation:
. Now all you do is calculate 12/100 which gives you
. now divide both sides by 0.12 to solve for y. This gives you 
43 is what percent of 106? This question is also a bit tricky, but instead of solving for y, you're solving for x. So plug in the known values, which gives you the equation:
. Divide both sides by 106 to get
and now multiply both sides by 100. this gives you
which is the answer 40.57%
What percent of 43 is 6. This is asking the same thing just in a different way. So percentage = unknown, entire number = 43, entire number * percentage = 6. With these values we get the equation:
. Divide both sides by 43 to get
now multiply by 100 to get
which is the answer 13.95%
