Mrs. O'Brien purchases 112 ounces of laundry detergent for $13.44. Mr. O'Brien purchases a 280 ounce container of laundry detergent for $19.60. What is the difference in the unit price per ounce for the laundry detergents Mr. And Mrs. O'Brien purchase
Answer:
$0.05 per ounce
Step-by-step explanation:
Mrs. O'Brien purchases 112 ounces of laundry detergent for $13.44.
Units price = Total cost of the detergent / number of ounces
= $13.44 / 112 ounces
= $0.12 per ounce
Mr. O'Brien purchases a 280 ounce container of laundry detergent for $19.60.
Units price =Total cost of the detergent / number of ounces
= $19.60 / 280 ounces
= $0.07 per ounce
Difference in the unit price per ounce for the laundry detergents Mr. And Mrs. O'Brien purchase = $0.12 per ounce - $0.07 per ounce
= $0.05 per ounce

Answer:
n = -6
x = -7
n = 27
Step-by-step explanation:
Question 1
-3n - n + 12 = 36
First we get all the variables to one side using subtraction property of equality.
-3n - n + 12 (-12) = 36 (-12)
-4n = 24
divide by the coefficient of n to isolate the variable
-4n/-4 = 24/-4
n = -6
Question 2
-2x - 3x - 15 = 20
-5x - 15 = 20
-5x = 35
x = -7
Question 3
3 + n/9 = 6
Isolate the n variable
n/9 = 6 - 3
multiply by 9
n = 27
Answer:
1. n = -6
2. x = -7
3. n = 27
Your family goes out for dinner on Sunday night. If the total bill came out to $175 but your parents had a 20% off coupon. How much will the entire meal cost if you also must pay 8% sales tax and a 18% tip?

a rectangle has vertices (0,0), (2k,0) and (0,k) find the fourth vertex
If a rectangle has vertices (0,0), (2k,0), and (0,k) the fourth vertex will be (4,8).
What is a rectangle?It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.
It is given that the rectangle has vertices (0,0), (2k,0), and (0,k).
A(0,0)
B(2k,0)
C(0,k)
D(x,y)
Since the opposite of the rectangle is the same it will be opposite to one of the coordinates shown in the graph.
To uniquely identify points on a plane, use ordered pairs and the rectangular coordinate system (x,y). Pairs that are ordered show position in relation to the origin.
The x-coordinate shows the left and right sides of the origin. Y-coordinate positions are above or below the origin.
Thus, if a rectangle has vertices (0,0), (2k,0), and (0,k) the fourth vertex will be (4,8).

Leonard is baking cookies for the
band fundraiser. He knows that he
can sell each cookie for $1.25. His
mom has also donated $25.
Altogether he expects that between
selling his cookies and the money
from his mom the band will receive
$67.50. How many cookies
did he bring to the fundraiser?
Answer:
He brought 34 cookies to the fundraiser.
Step-by-step explanation:
1.25x + 25 = 67.50
1.25x = 67.50 - 25
1.25x = 42.50
x = 42.50/1.25
x = 34
Answer:
34 cookies in total.
Step-by-step explanation:
Well if he is selling cookies for $1.25 each and has a starter of 25$, we can already mark off 25$ from $67.50. Now it's just simple division, so 42.50/1.25 is 34 cookies being sold.
2 (k-5) + 3k = k+6
so what does k=
Answer:
Step-by-step explanation:
2(k-5)+3k=k+6k=
We move all terms to the left:
2(k-5)+3k-(k+6k)=0
We add all the numbers together, and all the variables
2(k-5)+3k-(+7k)=0
We add all the numbers together, and all the variables
3k+2(k-5)-(+7k)=0
We multiply parentheses
3k+2k-(+7k)-10=0
We get rid of parentheses
3k+2k-7k-10=0
We add all the numbers together, and all the variables
-2k-10=0
We move all terms containing k to the left, all other terms to the right
-2k=10
k=10/-2
k=-5

The Dubois family has $5000 set aside for an upcoming vacation in the family plans to spend 1/4 of this amount on gasoline for the drive and motel rooms along the way and 1/2 of the remainder on meals how much does the Dubois family spend on meal
Answer:
$1875
Step-by-step explanation:
Money available with Dubois family = $5000
Money to be spent on gasoline and motel room = [tex]\frac{1}{4}[/tex] of the total amount
Therefore,
Money to be spent on gasoline and motel room = [tex]\frac{1}{4} \times 5000 = \$1250[/tex]
Remaining amount of money = Total amount - Money spent on gasoline and motel room
Remaining amount of money = $5000 - $1250 = $3750
As per question statement:
Half of the remaining money is to be spent on meals.
i.e. Money to be spent on meals = [tex]\frac{1}{2}\times \$3750 = \bold{\$1875}[/tex]
Therefore, the answer is:
$1875

A company makes steel rods shaped like cylinders. Each rod has a radius of 2 centimeters and height of 70 centimeters. How much steel will the company need to make 243 rods? Use 3.14 for pie, and round your answer to one decimal
Answer:
213,645.6cm³
Step-by-step explanation:
Area of a cylinder is expressed as;
V = πr²h
r is the radius = 2cm
h is the height = 70cm
Get the volume of one rod;
V = πr²h
V = (3.14)(2)²(70)
V = (3.14)(4)(70)
V = 879.2cm³
one steel = 879.2cm³
243 rods = x
Cross multiply;
x = 879.2 * 243
x = 213,645.6
The company will need 213,645.6cm³ volume of steel to make 243 rods
