Answer:
m= 15
Step-by-step explanation:
first you subtract 2/3 from both sides (m/9)+(2/3)-(2/3)= (7/3)- (2/3)
now you will have (m/9)= (5/3)
to get (m) on its own you have to multiply the both sides by 9
(m/9) times 9= (5/3) times 9
m= 45/3 or 15
Answer check:
substitute (m) for 15
(15/9)+(2/3)= (7/3)
first you should simply (15/9), so all of them will have a common denominator
(5/3)+(2/3)=(7/3)
(7/3)=(7/3)
Answer:
Step-by-step explanation:
Now we know that
sec²θ -tan² θ= 1 ,
So tan²θ =sec²θ - 1
So the left of the given equation will be
sec²20 + sec²40 +sec²80 - 3
So
1/cos²20+1/cos²49+1/cos²80 -3
Remember sec θ= 1/cosθ
So
= since secθ = 1/cosθ
we have
= 1.1324 + 1.7040 + 33.1634 - 3
= 35.9998 - 3
= 33
Answer:
1) A week: $151.74
2) A month : $606.96
3) A years : $7890.48
Step-by-step explanation:
Custodian at Movie Theater
pay:$9.95
per hours:
15.25 hours per week
How much do they make in
1) a- week
1 week = 15.25 hours
Hence,
1 hour = $9.95
15.25 hours = x
Cross Multiply
x = 15.25 × $9.95
x = $151.7375
Approximately = $151.74
2) A month
There are 4 weeks in a month
1 week = $151.74
4 weeks = x
Cross Multiply
x = 4 × $151.74
x = $606.96
3) A year
There are 52 weeks in a year
Hence,
1 week = $151.74
52 weeks = x
Cross Multiply
x = 52 × $151.74
x = $7890.48
Therefore, they made in :
1) A week: $151.74
2) A month : $606.96
3) A years : $7890.48
The answer is 270 because 250 + 8% = 270
