Answer:
Length = 15 inches
Step-by-step explanation:
Here we are given the width and the perimeter of the rectangle and we are required to find out our length. We will use the formula of perimeter in order to find the length.
The formula for perimeter
P=2(l+b)
where
l is length
b is width = 6
P is perimeter = 42
substituting them in formula we get
42=2(l+6)
dividing both sides by 2 we get
21 = l + 6
subtracting 6 from both sides we get
15 = l
Hence length is 15 inches
Answer:
5
Step-by-step explanation:
slope = 
The second y point is 16 and the first is -4, so:
(16) - (-4)
Which can be written as 16 + 4 because a double negative makes a positive. Do the same for the x points, -7 and -3:
(-7) - (-3)
(-7) + (3)
Now solve both of them:
16 + 4 = 20
(-7) + 3 = -4
Remember, the slope formula is y over x, so we still need to put it into the fraction form:
You can reduce this to 
, or 5.
With what????????????????????
I think you add 325 and 75 = 400
400 is the original temperature
Hopefully this helps...
The wording of this problem indicates that there was an illustration. Could you possibly share that illustration?
Working without an illustration:
If tan theta = 3, then tan theta = opp/adj = 3/1. This tells us that the opp side is 3 times as long as is the adj. side. Let x be the shorter side, i. e., let x represent the adjacent side; then y is the longer side and represents the opposite side.
Then y = 3x (the opp side is 3x the adj side in length).
Applying the Pyth. Thm. a^2 + b^2 = c^2,
x^2 + (3x)^2 = hyp^2 = (25 cm.)^2
So x^2 + 9x^2 = (625 cm^2)
10x^2 = 625 cm^2, or x^2 = (625 cm^2) / 10 = 62.5 cm^2
x = 7.91 cm. Therefore, y = 3(7.91) = 23.72 cm.
We were supposed to round off these answers to the nearest 10th cm.
Therefore, x = 7.9 cm and y = 23.7 cm
Would that be A, B, C or D?
