Step-by-step explanation:

We now that Brian wants the piece of fabric between 49 and 53 inches, this range is expressed like this

[tex]49<x<53[/tex]

Now, to choose the right answer, we have to transform the from feet to inches and see which one falls into this interval.

We know that 1 ft equals 12 in. If we have [tex]4\frac{3}{4}=\frac{19}{4} ft[/tex], how much inches would be?

[tex]\frac{19}{4}ft\frac{12in}{1ft}=57in[/tex]

As you can see, the choice A is not the right answer because is more than 53.

We do the same process. We know that,  [tex]4\frac{1}{2}=\frac{9}{2}ft[/tex] how much inches would be?

[tex]\frac{9}{2}ft\frac{12in}{1ft}=54in[/tex]

Choice B is not the answer neither, because it's outside the interval.

[tex]4\frac{1}{4}=\frac{17}{4}ft[/tex] how much inches would be?

[tex]\frac{17}{4}ft\frac{12in}{1ft}=51in[/tex]

As you can observe, choice C is in the interval. Therefore, the right answer is choice C, because 51 inches is between 49 and 53 inches.

Answer:

[tex]y=-2cos (2(x+\pi ))-1[/tex]

Step-by-step explanation:

From the graph, we can see that y = -3 when x  = 0.

So to check whether which of the given options is the equation of the given graph, we will set our calculator to the radian mode and then plug the value of x as 0.

1. y = -2 cos (4(x + pi)) - 1 = -2 cos (4(0 + pi)) - 1  = 3

2. y = 2 cos(x + pi) = 2 cos(0 + pi) = -1

3. y = -2 cos (2(x + pi)) - 1 = -2 cos (2(x + pi)) - 1 = -3

Therefore, the equation of this graph is  y = -2 cos (2(x + pi)) - 1.

The interest rate that will cause Helena's money to double in approximately 38 years is approximately 1.89%.

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.

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.

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.

Step-by-step explanation:

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.

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.

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.

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.

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.

Answer: C. |-4 - 3|

Step-by-step explanation:

x = -4

y = 3

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.

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.

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

It all depends on the value of x. Remember that x must be greater than or equal to 2 or else the number under the square root sign will be negative, which will result in a complex number. The domain is 2<=x and the range is 0<=x.

Graphing it looks like this:

The function h(x) = square root x-2 is a square root function that takes the input x, subtracts 2 from it, and then takes the square root of the result.

The function h(x) = √(x-2) represents a square root function. It takes the input x and subtracts 2 from it, and then takes the square root of the result. The function can be graphed as a curve that starts at (2, 0) and increases as x gets bigger. For example, if we plug in x = 4, h(4) = √(4-2) = √2.
