Answer: 1288- 5t , where t = number of hours Ahmad worked as a tutor this month.
Step-by-step explanation:
Given : The number of hours Ahmad works as a tutor that month = t
Combined hours of job = 92
The number of hours Ahmad works as a waiter = 92-t
Amount he got as tutor per hour = $ 9
Amount he will get as tutor = (Amount he got as tutor per hour ) x (t)
= 9t
Amount he got as waiter per hour = $ 14
Amount he will get as waiter = (Amount he got as waiter per hour ) x (92-t)
= 14(92-t)
= 14 (92)-14t [By distributive property]
= 1288 -14t
Combined amount he earned this month= Amount he will get as tutor + Amount he got as waiter per hour
= 9t+ 1288 -14t
=1288+9t-14t [Commutative property]
= 1288- 5t
So , the expression for the combined total dollar amount he earned this month:
1288- 5t
where t = number of hours Ahmad worked as a tutor this month.
Answer:
82.8
Step-by-step explanation:
i think this is correct dont get mad if im wrong but im 80% sure im right
Lets day the original price of the dvd player was $100,
36% marked down means you pay $64x
64x = $41.60
100x = 100/54 x 41.60 = 4160/64 = #65.00 = original cost
similarly, stereo tuners = 100/78 x 69.42 = 6942/78 = $89 original cost
DVD = 65- 41.60 = $ 23. 40 less
Stereo = 89- 69.42 = $ 19.58 less
Diffrence is $ 3.82
so your answer is the dvd player price was reduced by $3.82 more than the stereo tuner.
36 feet + 9 feet
= 45 feet
You are correct! The distance from where Debbie and Andy are standing to the coral reef is 45 feet in total.
Answer:
a) 2.2 × 10⁸ beats
b) 2.20 × 10⁸ beats
c) 2.207 × 10⁸ beats
Step-by-step explanation:
Data provided in the question:
Average heart rate of a typical person = 70.0 beats/min
Now,
In the given cases, the significance is on the significant figures after the decimal
Therefore,
the answer is will be provided accordingly
Now,
a) Time = 6.0 years
[since 1 significant figure after decimal. answer will be give in 1 significant figure after decimal ]
time in minutes = 6.0 × 365 × 24 × 60
= 3.1 × 10⁶ minutes
Total beats = Average heart rate × Time
= 70 × 3.1 × 10⁶
= 2.2 × 10⁸ beats
b) Time = 6.00 years
[since 2 significant figure after decimal. answer will be give in 2 significant figure after decimal ]
time in minutes = 6.00 × 365 × 24 × 60
= 3.15 × 10⁶ minutes
Total beats = Average heart rate × Time
= 70 × 3.15 × 10⁶
= 2.20 × 10⁸ beats
c) Time = 6.000 years
[since 3 significant figure after decimal. answer will be give in 3 significant figure after decimal ]
time in minutes = 6.000 × 365 × 24 × 60
= 3.154 × 10⁶ minutes
Total beats = Average heart rate × Time
= 70 × 3.154 × 10⁶
= 2.207 × 10⁸ beats
