Answer:
1 and 3/4 days are equal to 42 hours
Step-by-step explanation:
42 hours = (42 hours) (1 day / 24 hours)
42 hours = 42/24 days
Simplyfing the fraction: Dividing the numerator and denominator by 6:
42 hours = (42/6) / (24/6) days
42 hours = 7/4 days
42 hours = (4+3)/4 days
42 hours = (4/4+3/4) days
42 hours = 1 3/4 days
To determine how many days are equal to 42 hours, you divide 42 by 24 which results in 1.75. Therefore, 42 hours is equivalent to 1 and 3/4 days.
Explanation:In this mathematics problem, we are asked to convert 42 hours into a measurement of days. To begin with, we know that 1 day equals 24 hours. Therefore, to convert 42 hours into days we will divide 42 by 24.
The result of this division is 1.75. In terms of a day fraction, this value represents 1 and 3/4 days. As such, we can say that 42 hours is equivalent to 1 and 3/4 days.

A solution is 20% bleach. Which graph represents the number of liters of bleach, y, contained in x liters of solution?
Answer: Choice D (lower right corner)
If we have x = 0 liters of solution, then we have y = 0.20*x = 0.20*0 = 0 liters of bleach. Therefore the point (0,0) is on the graph.
The point (10,2) is also on the graph because x = 10 leads to y = 0.20*x = 0.20*10 = 2; meaning 10 liters of solution points to 2 liters of bleach.
The only graph that has both points (0,0) and (10,2) is choice D in the lower right corner.

To solve this problem, we first need to figure out how much tax will be applied to Neil's purchase. To do this, we need to multiply the tax rate (5%) by the cost of the washing machine ($445). But, we can't multiply percentages unless we change them to decimal form first. To do this, we need to divide the percentage by 100 (because 5 percent is a fraction out of a total 100 percent) or move the decimal point two spots to the left. This gives us the following:
0.05 * 445
If we compute this expression, we get:
$22.25
This means that Neil will be charged $22.25 in tax. However, the question asks for the total cost including tax, so we must add the original cost of the washing machine to the tax.
$445 + $22.25 = $467.25
Therefore, your answer is $467.25.
Hope this helps!

A rental company rents a luxury car at a daily rate of $37.68 plus $.25 per mile. Vanessa is allotted $120 for car rental each day. Write an equation to represent the cost C of renting a car and driving x miles. How many miles can Vanessa travel on the $120?
0.25x + 37.68 = C
[The company charges $0.25 per mile (x) plus $37.68, and C is the total amount of money/cost]
Vanessa has $120 [total amount of money she is given per day],
Since this is the total amount of money she has/can pay with, you can plug in 120 for C
0.25x + 37.68 = 120 Subtract 37.68 on both sides
0.25x = 82.32 Divide 0.25 on both sides
x = 329.28
Vanessa can travel 329.28 miles on the $120
The equation representing the cost of renting a car is C = 37.68 + 0.25x. Setting this equation equal to Vanessa's budget of $120 and solving for x, we find that Vanessa can travel about 329 miles on her budget.
Explanation:The cost of renting a car for a day can be represented by the equation C = 37.68 + 0.25x, where 'C' is the total cost and 'x' is the number of miles driven. Vanessa has $120 allotted for each day. Therefore to find out how many miles she can travel, we can set the equation equal to 120 and solve for 'x'.
So, 120 = 37.68 + 0.25x
Subtract 37.68 from both sides to isolate the term with 'x'.
82.32 = 0.25x
Finally, divide both sides by 0.25 to solve for 'x'.
x = 329.28
Therefore, Vanessa can travel approximately 329 miles on $120.

The distance between them is the difference. The mathematical operation for difference is subtraction.
Distance is a unit of measurement. Measurements cannot be negative so the absolute value sign is used to ensure the difference is positive.
The correct expression representing the distance between two points, X and Y, on a number line is D. [-4+3], which uses the absolute value to ensure a positive distance.
Explanation:The distance between two points X and Y on a number line can be calculated as the absolute value of the difference between their coordinates. In this case, the coordinates of X and Y are not provided, but we know we are looking for an expression that shows a positive distance regardless of whether X is to the left or to the right of Y on the number line. Therefore, we need the absolute value to ensure we get a non-negative result, which correctly represents the concept of distance.
Distance on a number line is given by the formula “|X - Y|”, which yields the magnitude of the difference between two points without considering direction, making it a positive number. Hence, the expression that represents the distance between two points, X and Y, on the number line in the provided options is D. [-4+3].
Using the provided expressions, [-4+3] means taking the absolute value of the result of “-4+3”, which indeed gives us the distance of 1 between the two points, since |-4+3| = |-1| = 1.

Final answer:
To find out how much dressing remains in the jar, subtract the amount of dressing poured onto the salad from the total amount of dressing made.
Explanation:
To find out how much dressing remains in the jar, we need to subtract the amount of dressing poured onto the salad from the total amount of dressing made.
Dakota combines 6 1/3 fluid ounces of oil and 2 3/8 fluid ounces of vinegar, which gives us a total of 8 17/24 fluid ounces of dressing.
She pours 2 1/4 fluid ounces of the dressing onto her salad. To find out how much dressing remains, we need to subtract 2 1/4 from 8 17/24. Converting the fractions to a common denominator, we have (55/24) - (9/4) = 46/24 - 9/4 = 37/24. This means that 37/24 fluid ounces of dressing remain in the jar.

Tina uses a $50.00 gift certificate to buy a pair of pajamas for $17.97, a necklace for $25.49, and 3 pairs of socks that each cost the same amount. Tina has to pay $0.33 because the gift certificate does not cover the total cost of all the items. How much does each pair of socks cost?
Answer:
$2.29
Step-by-step explanation:
She spent the $50.00 gift certificate plus $0.33.
$50.00 + $0.33 = $50.33.
She spent a total of $50.33.
The pajamas cost $17.97.
The necklace cost $25.49.
The total cost of the pajamas and necklace is:
$17.97 + $25.49 = $43.46.
Since she spent a total of $50.33, we now subtract the amount she spent on the pajamas and necklace to find out the cost of the three pairs of socks.
$50.33 - $43.46 = $6.87
The three pairs of socks cost a total of $6.87.
Since all pairs of socks cost the same amount, we now divide $6.87 by 3 to find the price of each pair of socks.
$6.87/3 = $2.29
Each pair of socks costs $2.29.

Compute the open-to-buy for a store with planned purchases of $3,500. Orders received total $975 and merchandise ordered totals $1,200.
Answer:
$1,325
Step-by-step explanation:
All we have to do is to identify which amount is the goal, and which amount(s) are taken steps toward that goal. Once you identify those, deduct whatever amount(s) that have got you closer to the goal and you will get what is still left to achieve. Or as stated in this example, the open-to-buy amount.
Goal:
$3,500 (as planned)
Steps made toward reaching planned goal:
Orders Received: $975
Merchandise ordered: $1,200
Compute the goal minus the steps achieved so far and Voila! You will get your open-to-buy amount.
$3,500-$975-$1,200=$1,325

Helena deposited $89 into a saving account. According to the rule of 72 what interest rate will cause her money to double in approximately 38 years
The interest rate that will cause Helena's money to double in approximately 38 years is approximately 1.89%.
Explanation:An interest rate is the percentage at which interest is charged or paid on a loan, investment, or financial instrument over a specified period. It represents the cost of borrowing money or the return on invested capital. Interest rates are set by financial institutions, central banks, and market forces and influence economic activity. They can be calculated by the rule of 72 as well.
To find the interest rate that will cause Helena's money to double in approximately 38 years, we can use the rule of 72. The rule of 72 states that by dividing 72 by the interest rate, we can estimate the number of years it takes for an amount to double. In this case, if we divide 72 by 38, we get an interest rate of approximately 1.89%. Therefore, an interest rate of approximately 1.89% will cause Helena's money to double in approximately 38 years.

Solve each equation. -9X+1=-80
Answer:
x=9
Step-by-step explanation:
-9x + 1 = -80
-9x = -81 substract 1 from both sides
x= 9 divide both sides by -9
The solution to the equation -9x + 1 = -80 is x = 9
To solve the equation -9x + 1 = -80, we aim to isolate the variable x on one side of the equation.
First, we can subtract 1 from both sides to get rid of the constant term:
-9x + 1 - 1 = -80 - 1
This simplifies to:
-9x = -81
Next, we divide both sides by -9 to solve for x:
(-9x) / -9 = (-81) / -9
This gives us:
x = 9
Therefore, the solution to the equation -9x + 1 = -80 is x = 9. When we substitute x with 9 in the original equation, we get -9(9) + 1 = -80, which is true, confirming the solution.
