Answer:
x is (-infinite, -12) and (-6, infinite)
Step-by-step explanation:
Meaning that x is less than -12 and greater than 6. I think...
Answer:
12-inch by 16-inch- it's the largest available and can be reduced to scale for smaller photos.
Step-by-step explanation:
-Given the dimensions 7-inch by 9-inch, 8-inch by 10-inch, and 12-inch by 16-inch:
#If Alice buys 7-inch by 9-inch and the photo turn's out to be a 8-inch by 10-inch or 12-inch by 16-inch then part of her photo will be cut off.
Hence, Don't buy.
#If Alice buys 8-inch by 10-inch and the photo turn's out to be a 12-inch by 16-inch then part of her photo will be cut off. However, if the photo is a 7-inch by 9-inch then it will fit.
Hence, don't buy.
#If Alice buys a 12-inch by 16-inch and the photo turns out to be smaller than expected the she can always print it out and trim or reduce the to scale excessive print paper to the desire dimensions.
Hence, buy the 12-inch by 16-inch since it's the largest available and can be reduced to scale for smaller photos.
Answer:
2.25 (or 
) g/mL
<u>Skills needed: Density</u>
Step-by-step explanation:
1) Briefly, let's cover what density is:
- It is 
- Measures the mass per unit of volume
- In this situation the formula for density is: 
---> 
is the final mass
---> 
is the initial mass
---> 
is the final volume
---> 
is the initial volume
2) In this case, we start out with a mass of 180 grams as stated in the problem, and also 50 mL of water initially.
This means that:
- is 180 g
- is 50 mL
3) Also, we end up with 270 g in mass, and 90 mL of water finally.
- is 270g
- is 90 mL
4) We can find density by substitute given the values above:
5) Our answer is 2.25 g/mL (since mass is grams (g), and volume is milliliters (mL) in the problem above).
