Answer:
Answer choice A
Step-by-step explanation:
For the first letter, there are 26 options, as there are for the second and third letter. For each of the three numbers, there are 10 digits to choose from. Therefore, 26*26*26*10*10*10=17,576,000, or answer choice A. Hope this helps!
Answer: B = 73
Step-by-step explanation:
Since A = 17 degrees and there's already a right angle (90 degrees)
They add up to 107 degrees meaning the last angle is 73 because
the sum of interior angles add up to 180.
I'm sorry I couldn't find the other ones ( I don't have time )
but I'll give you a hint. You'll need to use Sine, Cosine, or Tangent
Answer:
x = 2.285 hours
y = 2.1425 feet
Step-by-step explanation:
Let us say that y represents the depth of the pool in feets and x represents the time in hours
The two set of equations are
y = 1/2x + 1
y= -1.25x + 5
Solving the above two equations we get
Subtracting eq (1) from eq (2), we get -
y-y = -1.25 x -0.5 x + 4
0 -1.75 x + 4
x = 4/1.75
x = 2.285 hours
y = 0.5 * 2.285 + 1
y = 2.1425 feet
Answer:
(1,11)
Step-by-step explanation:
11=8(1)+3
11=8+3
11=11
Answer:
x - 2y + 1 = 0
Step-by-step explanation:
This line goes through the points (-3, -1) and (3, 2). Going from the first oint to the second, we see that x increases by 6 (this is the 'run') and y increases by 3 (this is the 'rise'). Thus, the slope is m = rise / run = 3/6 = 1/2.
Starting with the slope-intercept form y = mx + b, we get
y = 2 = (1/2)(3) + b, or (after multiplying all terms by 2):
4 = 3 + 2b, or 1 = 2b, or b = 1/2
Then the equation of this line is y = mx + b, or y = (1/2)x + 1/2.
We must put this into standard form. Multiplying all terms by 2 yields
2y = x + 1, or x - 2y + 1 = 0
