Answer:
240
Step-by-step explanation:
3 times 80 is 240 and 7 times 80 is 560. added together is 800. 800 is the total amount of people, so it works.
$50 are added per week
$550 is the starting amount
since x = # of weeks, and 50 is being multiplied by that, it is known that each week, you are earning an additional $50
since when x = 0, aka at the beginning, y = 550, that is the amount you started with
Answer:
The restaurant expect to sell more than 100 omelets
Step-by-step explanation:
we know that
The restaurant sell 6 omelets every 15 minutes
The restaurant serves breakfast from 6:00 am until 10:30 am
10:30 am-6:00 am=4.5 hours
Convert 4.5 hours to minutes
so
using proportion
Find out the number of omelets that the restaurant expect to sell in 270 minutes
Let
x ----> the number of omelets
therefore
The restaurant expect to sell more than 100 omelets
Answer:
For the triangles just use the equation a^2 + b^2 = c^2. c is the hypotenuse and a and b are the other two sides. if you have at least 2 of the sides you can change the equation to find the other side. Now for the second shape (the weird rectangle-triangle thingy) you just have to do 17-11= 6 witch gives you a. B is already given to you b = 8, so all you have to do is 6^2 + 8^2 witch is 100 then you can square root it with becomes 10. so your x = 10 for that shape.
