Store A sells boxes of rice for $2.50 each.
Store B sells rice by the pound for $2.50 per pound.
The cost of an amount of rice at either store can be modeled by the function c(n) = 2.5n, where n is the number of boxes for Store A and n is the number of pounds of rice for Store B.
The domain of c(n) = 2.5n is all the real numbers.
For each store, drag the restriction needed on values of n for c(n) to model each situation.
Answer:
Step-by-step explanation:
Store A: Sells rice in boxes= whole numbers greater than or equal to zero
Store B: Sells rice by the pound= any number greater than or equal to zero

What’s the area of this figure?
Answer:
374 mm
Step-by-step explanation:
There are two rectangles and one triangle. This means that we need to add the sum of two rectangles and one triangle together.
Rectangle 1:
19*9=171
Rectangle 2:
19*9=171
Triangle:
8*23*1/2=32
(We divide by 1/2 because it's a triangle)
Now we add them together.
171+171+32=374
In the end, the answer is 374. I didn't show all of my work because most of it was done mentally.

3x {+ 2y = 23
x {– 2y = 8
Answer:
([tex]\frac{31}{4} , \frac{-1}{8}[/tex])
Step-by-step explanation:
use substitution:
3x+2y=23
x=2y+8
plug in 2y+8 for x
3(2y+8)+2y=23
distribute:
6y+24+2y=23
combine like terms:
8y+24=23
solve the equation:
y=-1/8
substitute -1/8 for y:
x=2(-1/8)+8
solve the equation:
x=31/4

Answer:
Step-by-step explanation:
Supplementary means 2 angles adding up to 180 or the line of AEF in this case
so supplementary pairs like DEH and HEF would add up to 180, same with DEJ and JEF
Answer:
Angle DEH and angle HEJ and HEK and KEF add up to 180 degrees
Step-by-step explanation:
Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. ... For example, a 50-degree angle and a 40-degree angle are complementary; a 60-degree angle and a 120-degree angle are supplementary.

Clare estimates that her brother is 4 feet tall. When they get measured at the doctor’s office, her brother’s height is 4 feet, 2 inches.
1. Should Clare's or the doctor's measurement be considered the actual height? Explain your reasoning.
2. What was the error, expressed in inches?
3. What was the error, expressed as a percentage of the actual height?
Answer:
Percentage of error by Clare is estimated as 4.1667 %
Step-by-step explanation:
