Answer:
Martha earns $65.6 over the weekend.
Step-by-step explanation:
Brownies sold by Martha on Saturday = 60
Cookies sold by Martha on Saturday = 42
Brownies sold by Martha on Sunday = 28
Cookies sold by Martha on Sunday = 54
Total brownies sold by Martha over the weekend = ![60+28=88](https://tex.z-dn.net/?f=60%2B28%3D88)
Total cookies sold by Martha over the weekend = ![42+54=96](https://tex.z-dn.net/?f=42%2B54%3D96)
Cost of a brownie = $0.20
Cost of a cookie = $0.50
Total cost of brownies sold over the weekend = ![88\times \$0.20 = \$17.6](https://tex.z-dn.net/?f=88%5Ctimes%20%5C%240.20%20%3D%20%5C%2417.6)
Total cost of cookies sold over the weekend = ![96\times \$0.50 = \$48](https://tex.z-dn.net/?f=96%5Ctimes%20%5C%240.50%20%3D%20%5C%2448)
∴ Total money Martha earned over the weekend =
(Answer)
Set it up like a regular equation. I used:
![3x+135 \ \textless \ 6x](https://tex.z-dn.net/?f=3x%2B135%20%5C%20%5Ctextless%20%5C%20%206x)
As you can see, however, I inserted the "less than" symbol rather than the equal sign because values greater than a certain value can also equal "x". Solve it like a normal equation and you will arrive at:
<u>
</u>
![x \ \textgreater \ 45](https://tex.z-dn.net/?f=x%20%5C%20%5Ctextgreater%20%5C%20%2045)
This means that, as long as x is greater than 45, "6x" will be greater than "3x+135". Thus, if you bring 46 students, the Science Center will cost less.
Answer:
Fastest to slowest = 6.08 > 6.4 > 6.72 > 6.75 > 7.03
Step-by-step explanation:
The person who completes the 50-meter race within the shortest possible time is the fastest sprinter. Here, the third sprinter crossed the line in 6.08 seconds, whereas the 4th sprinter crossed the line in 7.03 seconds. That is why the third sprinter has won the race, and he becomes the fastest. On the contrary, the fourth person takes the most time to complete the race, meaning he is the slowest.
Let the distance be x miles
Time = Distance / speed
Time taken by Mike to go to his friend's house = x / 40 hours
Time taken by him to return = x / 45 hours
Total time = x / 40 + x / 45 = 4 hours
= 9x + 8x = 1440 miles
17x = 1440
= x = 1440 ÷ 7
= x = 84.706
Time taken to return home = 84.706 /45= 1.882 hours .
Therefore , Mike took 1.882 hours to reach home .
