Answer:
(0.25)⋅(0.044) = 0.011
Step-by-step explanation:
Two students have different ways to calculate (0.25)⋅(0.044) as a decimal.
Show, in detail, how each student might compute this product. (upload your work when complete)
We are given:
(0.25)⋅(0.044)
= 0.25 × 0.044
a) For Elena
Elena says, "I find 25⋅ 4.4 and then move the decimal point."
What Elena did was she multiplied both
number by 100
= (0.25 × 100) × (0.044 × 100)
We add up the decimal points from 0.25 and 0.044 = 5
Hence, the answer we get in step 1 is divided by 100000 in other it move the brackets
(0.25 × 100) × (0.044 × 100)/100000
= 0.011
b) For Diego
Diego says, "0.25 is the same as 1/4, so I found 1/4 of 0.044."
Diego converted 0.25 to fraction
= 0.25 × 100/100
= 25/100 = 1/4
Since, (0.25)⋅(0.044)
= 0.25 × 0.044
Then:
1/4 of 0.044
= 1/4 × 0.044
= 0.011
Answer:
-2/3
Step-by-step explanation:
because this is in slope intercept form, m is the slope, so in this case -2/3 is the slope
parallel lines always have the same slope and different y-intercepts
a parallel line could be y=-2/3 +15

Answer:
- 0.25|h -1600| -400
- 1000
- 2200
Step-by-step explanation:
Once again, you can choose the correct equation by finding the one that gives d=0 for h=0. (Note that the problem statement requires the independent variable to be h, not x.)
Then you can use that equation to find h for d=-250:
-250 = 0.25|h -1600| -400
150 = 0.25|h -1600|
600 = |h -1600|
This resolves to two equations:
- -600 = h -1600 . . . ⇒ . . . h = 1000
- 600 = h -1600 . . . ⇒ . . . h = 2200

Or, you can realize the distance from the west end is 4 times the depth. At a depth of 250 ft, that distance is h=1000 ft. That is 600 ft from the center, so 1200 ft from the same depth on the other side of the crater, which is at h=2200 ft.
