Answer: 16
Step-by-step explanation:
Total number of laptops ordered= 650
Number of laptops tested= 40
Number of laptops that takes more than 30 seconds to start up= 1
To get the number of laptops that will take 30 seconds to start in the whole shipment goes thus:
Let the number of laptops that will take more than 30 seconds be represented by y.
1 : 40 = y : 650
1/40 = y/650
Cross multiply
40y = 650
y= 650/40
y= 16.25 which approximately gives 16.
There are expected to be 26 laptops that takes more than 30 seconds to start.
Step-by-step explanation:
100% = 32
73% = 73×1% = 73×100%/100 = 73×32/100 = 23.36 pounds.
for an estimate I would round up to 75% = 3/4, and then calculate quickly 32 × 3/4 = 8×3 = 24 pounds.
Unsure of what you mean by "y1."
If you wish to solve this eqn for y, do this:
-5y = - 3x + 20,
-3x + 20
y = ---------------- = (3/5)x - 4 (answer)
-5
The midpoint of that segment is (-8,-8).
The greatest common factor would be 8
