90 • 0.06 = 5.4
90 • 0.2 = 18
5.4 + 18 = 23.4
90 + 23.4 = 113.4
So your answer is 113.40 dollars
Answer:
The average rate will be: 0.7 inches/hour
Hence, Option (4) is correct.
Step-by-step explanation:
As the average rate = change in y-values/change in x values
= Δy/Δx
From the table, it is clear that over the time interval 't=2' to 't=7', the values
snow depth 'd' inches change from d=1.5 to d=5.
Therefore,
Average rate = Δy/Δx
= (5-1.5) / (7-2)
= 3.5/5
= 0.7 inches/hour
Therefore, the average rate will be: 0.7 inches/hour
Hence, Option (4) is correct.

Answer: This is true because everything in the first equation was multiplied equally to get to the second equation. Every part was multiplied by three. The first equation is x-7=3 and the second can be seen as 3(x-7=3). The three will not affect x seeing that the entire equation had the same thing done to it.
Answer:
Correct choice is 4.
Step-by-step explanation:
Tyrone determines it takes him 58.2 minutes to travel 30 miles to work, then he travels with speed
![\dfrac{30}{58.2}=\dfrac{300}{582}=\dfrac{50}{97}\ \text{miles per minute}.](https://tex.z-dn.net/?f=%5Cdfrac%7B30%7D%7B58.2%7D%3D%5Cdfrac%7B300%7D%7B582%7D%3D%5Cdfrac%7B50%7D%7B97%7D%5C%20%5Ctext%7Bmiles%20per%20minute%7D.)
If 1 mile = 5,280 feet, then his speed is
![\dfrac{50}{97}\cdot 5280=\dfrac{264000}{97}\ \text{feet per minute}.](https://tex.z-dn.net/?f=%5Cdfrac%7B50%7D%7B97%7D%5Ccdot%205280%3D%5Cdfrac%7B264000%7D%7B97%7D%5C%20%5Ctext%7Bfeet%20per%20minute%7D.)
Since 1 minute = 60 seconds, then his speed is
![\dfrac{264000}{97\cdot 60}=\dfrac{4400}{97}\approx 45.36\ \text{feet per second}.](https://tex.z-dn.net/?f=%5Cdfrac%7B264000%7D%7B97%5Ccdot%2060%7D%3D%5Cdfrac%7B4400%7D%7B97%7D%5Capprox%2045.36%5C%20%5Ctext%7Bfeet%20per%20second%7D.)
