Answer:
x=-7
Step-by-step explanation:
0.3(8-2x) - 1.2(2-3x) < -21
2.4 - 0.6x - 2.4 + 3.6x < -21
3x < -21
x < -7
The y is going to be 165 if the x is 54 because you need to multiply by 3 each time.
I believe c sorry if I’m wrong
Answer:
7.8 × 10-5 meters
Step-by-step explanation:
the length of the a human hair= 8.4 x 10^-5
length of the vicuna hair:0.000006 = 0.6 x 10^-5
===========================================
difference between human hair and vicuna hair:
8.4 x 10^-5 - 0.6 x 10^-5 = 10^-5 ( 8.4 - 0.6)
= 10^-5 (7.8)
= 7.8 x 10 ^-5 meters
Answer:
Harriet's estimated length is between 44.1 inches and 47 inches.
Step-by-step explanation:
Let the error be x.
so, x<4%
Now, if error is 1%
45 1/2 + 1% of 45 1/2
or, 91/2 + 1/ 100 × 91/2
= 46
Now,
45 1/2 - 1% of 45 1/2
or, 91/2 - 1/100 × 91/2
= 45.1
Now,
if error is 3%
45 1/2 + 3% of 45 1/2
or, 91/2 + 3/100 × 91/2
= 47
OR
45 1/2 - 3% of 45 1/2
= 91/2 - 3/100 × 91/2
= 44.1
