Each bottle of perfume contains
2.1
2.1 fluid ounces of perfume. The store sells
30
30 bottles. How many fluid ounces of perfume did the store sell in total?
Answer:
Total amount of fluid sold = 63 ounces

Felix has $50 in a savings account that earns 5% interest, compounded annually. To the nearest cent, how much interest will he earn in 2 years?
Answer:
$55.13
Step-by-step explanation:
50 * 1.05 = 52.5
We do this step twice because the interest is for 2 years.
52.5 * 1.05 = 55.125
This rounds up to 55.13, your final answer!

pretty self explanatory(ANSWER ASAP) Solve the inequality.
Answer:
y > -6
Step-by-step explanation:
add 6 over from the left side to get y by itself
this simplifies to -6
since this was subtraction, you flip the equation and the sign
so it changes to y > -6

The graph of the function y = 3(x - 2)^3 + 7 is translated 2 units to the
right and then 4 units down. Write the equation of the final graph.
Answer:
y = 3(x - 4)^3 + 3Step-by-step explanation:
Given function
y = 3(x - 2)^3 + 7Translation to the right achieved by adding - 2 to x-value
Translation down achieved by adding -4 to y-value
So the function becomes:
y = 3(x - 2 - 2)^3 + 7 - 4 ⇒y = 3(x - 4)^3 + 3What is the ratio of W's to P's? W W W W W P

Caleb and Landon work at a dry cleaners ironing shirts. Caleb can iron 30 shirts per hour, and Landon can iron 15 shirts per hour. Caleb worked 2 more hours than Landon and they ironed 330 shirts between them. Write a system of equations that could be used to determine the number of hours Caleb worked and the number of hours Landon worked. Define the variables that you use to write the system
Answer:
The system of the equations is x - y = 2, 2x + y = 22, where x is the number of hours that Caleb worked and y is the number of hours that Landon worked
Step-by-step explanation:
Assume that Caleb worked for x hours and Landon worked for y hours
∵ Caleb worked for x hours
∵ Landon worked for y hours
∵ Caleb worked 2 more hours than Landon
→ That means Caleb hours = Landon hours + 2
∴ x = y + 2
→ Subtract y from both sides
∴ x - y = 2 ⇒ (1)
∵ Caleb can iron 30 shirts per hour
∵ Landon can iron 15 shirts per hour
∵ They ironed 330 shirts between them
→ Multiply x by 30 and y by 15, then equate their sum by 330
∴ 30x + 15y = 330
→ Divide both sides by 15 to simplify the equation
∴ 2x + y = 22 ⇒ (2)
The system of the equations is x - y = 2, 2x + y = 22, where x is the number of hours that Caleb worked and y is the number of hours that Landon worked

A farmer has a square field that is 1 mile wide by 1 mile long. Her irrigation system can water the northern 0.5 miles of her field. If her tomatoes are planted in a strip 0.3 miles wide, what is the area of her watered tomatoes?
Answer:
0.15mile^2Step-by-step explanation:
Step one:
Given
lenght of field L= 1mile
width of field W= 1 mile
Required
The area that can be watered
we are told that the system can water 0.5miles North
This represents the length that can be watered
and the width of the tomatoes area is 0.3miles
Therefore the area that can be watered is
A= 0.5*0.3
A=0.15mile^2
There are 160 cal in 4 ounces of ice cream how many calories will be in 6 ounces of ice cream
Answer:
There will be 240 calories in 6 ounces of ice cream.
Step-by-step explanation:
Well if you take 160 and divide it by 4 you would get 40.
Meaning every ounce is 40 calories. 1 ounce = 40 cal.
40 x 6 = 240 calories.
(6x - 4y = 11
6x + 14y= -12
