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

Answer:
#1 is 10
# 2 is
6 + 7 + 8 + 9 + 10 + 10 + 10 + 12 + 14 + 14 = 100/10. The (Mean) = 10
(6- 10) + (7- 10) + (8- 10) + (9- 10) + (10- 10) + (10- 10) + (10- 10) + (12- 10) + (14- 10)
4 + 3 + 2 + 1 + 0 + 0 + 0 + 2 + 4
= 16/10 = 1 6/10
The (MAD) = 1 6/10

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

Step-by-step explanation:
Joni earns $300 per week. If she gets a 25% raise, how much more money will she earn each week?
Answer:
$375 ($75 more dollars)
Step-by-step explanation:
25% of 300 is 75, so, 300+75 is 375.
Answer:
[tex]\huge\boxed{$75}[/tex]$75
Step-by-step explanation:
Joni currently earns $300 per week (given)
To find how much more she will earn each week, write an expression adding the original pay and the raise amount.
$300 + 25%
Find 25 as a decimal for multiplication
25% = 25/100 = 0.25
Write an expression to represent the scenario
Expression example 1:
$300 + 0.25(300)
This expression adds the original pay and the new raise together.
Expression example 2:
$300 (1.25)
This expression already takes the new pay into account by finding 125% of the original pay.
Simplify both expressions
Expression 1:
$300 + 0.25(300)
$300 + $75
$375
Expression 2:
$300 (1.25)
$375
Both expressions represent the same scenario and therefore come out to the same result. Now that we know how much Joni made after the raise, we need to find how much more money she will earn in a week with the following equation.
New amount - original amount = amount increase
Substitute known values into the equation
$375 - $300
Simplify
$75
Joni will earn $75 more each week.

Step-by-step explanation:
if the volume of a cylinder is given by v=pi*h*r^2 lets find each volume and find their ratio. volume of a is 50.24 and volume of c is 200.96. so the ratio is 200.96:50.24. let's simply this by saying 200.96/50.24 to see how many of the smaller cylinders A it takes to equal 1 of the larger cylinder C. it is 4. the ratio is 1:4. 1 large cylinder C is equal to 4 smaller cylinders A

Han has 10 cubes, every 5 inches on aside. Which expression shows the total volume of Han's cubes? *Choose All That Apply*
(a) (10⋅5)^3
(b) 10⋅5^3
(c) 5⋅5⋅10
(d) (10⋅5)^2
do you guys know this?
Answer:
Step-by-step explanation:
The house is split into two cubes: The main house, and the "chimney"
The volume of the main part of the house is 20*20*21 mm=8,400mm cubed
The chimney's volume = 11*5*2mm = 110 mm cubed
Now, you just need to add them up.
8,400+110 mm cubed = 8,510 mm cubed

Last Season, A Lacrosse player scored 41 goals in 15 games, So far this season, the player has scored 24 goals in 9 games.
A. Does the player have a greater number of goals per game this season compared with last season?
(I think it is a no. If it is not no, explain)
B. Supposed the player plays in as many games this season as last season and continues to score at this season's rate. Write and solve A proportion to find the number of goals the player will score this season
Answer:
1.) No
2.) 40 goals
Step-by-step explanation:
Given the following :
Last season:
Games played = 15
Points scored = 41
Current season:
Games played = 9
Points scored = 24
A)
Last season:
Goals per game = total points / number of games
Goals per game = 41 / 15 = 2.733
Current season :
Goals per game = total points / number of games
Goals per game = 24 / 9 = 2.667
Last season's goal per game is greater than that of current season.
B)
Current rate = goals / games = 24/9 - - - (1)
Let points to be scored this season = y
Ratio of y to number of games played last season = y / 15 - - - (2)
Equate both
24 / 9 = y / 15
9 * y = 24 * 15
y = 360 / 9
y = 40
Answer:
A=no B=no
Step-by-step explanation:
in the first season you need to divide 41 into 15 to see how much he scored in 1 game which is 2.7333333333 continued
next you need to find second season which is 24/9 2.6666666666 continued
easy, 2.666666666 times 15 is too inacurate so do 24/9*15 which is 40 so the answer is also no

Answer:
66
Step-by-step explanation:
Use the equation y=x+2. y is her height, and x is her arm length. so, when 64 is x, fill in the black and do 64+2, which is 66!
copy and paste:
If she is 64 inches tall, her arms are 66 inches because 66=64+2.
