5/9 and 11/21
LCM of the denominators is 63
changing their denominators to all have a common denominator of 63:
5(7)/63 = 35/63
11(3)/63 = 33/63
from the above;
5/9 > 11/21.

Use the Addition Property for integrals to find values for r and s.
Answer:
Lower limit: -5
Upper limit: -15
Step-by-step explanation:
Notice that the property of addition of integrals shown below, gives the answer to the problem:
[tex]\int\limits^b_a {f(x)} \, dx +\int\limits^c_b {f(x)} \, dx =\int\limits^c_a {f(x)} \, dx[/tex]
therefore, the values you need to type inside the two limits of the integral are:
Lower limit: -5
Upper limit: -15
Nikki’s Pizza Joint charges $14 for a super-duper cheese pizza and $2 for each extra topping. How many toppings can you order for $25?
Answer:
5 toppings
Step-by-step explanation:
The formula is y=2x+14 with x being the number of toppings and y the total price.
Plug in 25 as y to see how much x would be at that price.
25=2x+14
11=2x
x=5.5
You can't get half of a topping so you would have to round down to 5 toppings.
Answer:
you can order 4 toppings but if you wanted a specific answer, it would be 5.5
Step-by-step explanation:
you have 25, subtract 14, you have 11, divide 11 by 2, you get 5.5 but you cant get half so you have 4 if you round it

Alyssa is helping to set up drinks and snacks for a luncheon.
Alyssa has 4.5 liters of lemonade to pour into pitchers. Each pitcher holds 0.9 liter of lemonade. If Alyssa pours an equal amount of lemonade into each pitcher, how many pitchers does she fill?
Alyssa drew the model below to show how many pitchers she fills.
The grids represent the amount of lemonade that Alyssa has. The lines represent Alyssa's division.
Answer in at least 2 complete sentences.
Is Alyssa's model correct?
Explain how do you know?
Answer:
Haha this isn't college Alyssa fills 5 pitchers. 4.5 divided by the liters of lemonade(0.9) equals 5 pitchers because 9x5=45 so, 4.5 liters of lemonade divided by 0.9 liters equals 5 pitchers.

The weight of an object on the moon varies directly as its weight on earth. A person who weights 27.4 lb on the moon weights 164.4 lbs on earth. How many pounds would be a 270 lb person weigh on the moon?
Answer:
45 lb
Step-by-step explanation:
You can simple use unitary methods.
It is a simple visualization:
27.4 on moon = 164.4 on earth
(27.4/164.4) on moon = 1 on earth
270(27.4/164.4) on moon = 270 on earth
45 on moon = 270 on earth
Or, use, unitary method,
=> 164.4/27.4 = 270/x
=> x = (270 × 27.4)/164.4
=> x = 45
Or, use the concept "weight becomes 1/6 of the real one(of that on earth)".
270 lb on moon = 270/6 = 45 lb
