Answer:
Well 7 x 10^-5 would mean you moved the decimal 5 Times because the power at the end of 10 is how many times the decimal is moved till it’s a number greater or equal to 1. So the scientific notation of that is: 0.00003
The -5 means that it was moved to the right. Positive always means left. Negative is always right.
Answer:
89–100
Step-by-step explanation:
Let x represent the grade on the fifth test. The average for 5 tests wants to be between 80 and 90, so we have ...
80 ≤ (78 +62 +91 +80 +x)/5 ≤ 90
Multiplying by 5 gives
400 ≤ 311 +x ≤ 450
Subtracting 311 gives the range for the fifth test grade.
89 ≤ x ≤ 139
Since the maximum available score is 100, the range on the 5th test for an overall B grade is ...
89 ≤ x ≤ 100 . . . . where x is the grade on the 5th test
Answer:
3z+3x=2
Step-by-step explanation:
3z+8=12+3x-2
collecting like terms
3z-3x=12-2-8
3z-3x=2
3z=2+3x
divide through by three
z= ⅔+x
Answer:
x=15
Step-by-step explanation:
they all add up to 360degrees
The answer is 94 because the ?angle is the alternating exterior angle of the given angle which makes them congruent.
