Answer:
= 0.315
Step-by-step explanation:
hope this helps :)
Log7 (x+3) - log7 (x-3) = 1
log7 [(x+3) / (x-3)] = 1
raise both sides to power of 7
(x+3) / (x-3) = 7
7x – 21 = x + 3
6x = 24
x = 4
Answer:
$4
Step-by-step explanation:
27 - 3 = 24
24 ÷ 6 = 4
have a goodnight! :)
Answer:
The student whose marks between quarter grades & topic tests score has maximum proportionate deviation
Step-by-step explanation:
Percentage change shows the proportionate change in a value, from the initial point. Formula = ( Change / Old ) x 100
Percentage change in students' quarter grades from topic tests score =
[ ( Quarter topic test score - Topic test score ) / Topic Test score ] x 100
Eg : Quarter Grade = 80, Test score = 60.
Percentage change = [ (80 - 60)/ 60 ] x 100 = ( 20 / 60 ) x 100 = 33%
So, student who has this maximum proportionate or percentage deviation between quarter grades & topic tests score - that student change would be represented by the point farthest from 0 on a number line.
Answer:
x = 12.2
Step-by-step explanation:
sin theta = opp / hypotenuse
sin 55 = 10 /x
Multiply each side by x
x sin 55 = 10
Divide each side by sin 55
x = 10 / sin 55
x =12.20774589
Rounding to the nearest tenth
x = 12.2
