The original price of the ski jacket is $184.

What is price?

The sum of money paid or the amount of compensation offered by one party to another in exchange for goods or services is known as a price. The cost of production can take on different names depending on the circumstance. If the item is a "good" in a commercial transaction, the cost of the item will probably be referred to as its "price".

Given:

Paula bought a ski jacket on sale for $8 less than half its original price.

She paid $84 for the jacket.

We have to find the original price of the ski jacket.

Let

The original price = x

The amount she bought it = x/2 - 8

She paid $84 for the jacket

Therefore,

84 = x/2 - 8

Add 8 on both sides,

84 + 8 = x/2 - 8 + 8

92 = x/2

x = 184

Hence, the original price of the ski jacket is $184.

Option C is correct, No, to be congruent, objects need to have the same size and shape.

The figures are said to be congruent if one of them may be generated following a string of stiff motions of the other. Additionally, this indicates that the sides and angles of both of these figures are identical. Congruent angles are those of these congruent figures that have the same measure. Congruent sides are those of these congruent figures that have the same measure.

Given a phrase If two objects are the same color but do not have the same shape or size, are they congruent,

The objects are not congruent.

for the congruent object shape and size should be equal, and there is no relation for color in congruent objects.

And it is also not important that objects should be triangles only there can be any object whose shape and size are equal they are said to be congruent.

Hence, option C is suitable for the condition.

The number of ounces of oats and dried fruit are needed for different numbers of servings are as follows:

A ratio can be defined as a mathematical expression that's used to denote the proportion of two (2) or more quantities with respect to one another and the total quantities.

In this scenario, we know that the ratio of the number of ounces of oats (O) in one serving to the number of ounces of dried fruit (D) in one serving is equal to 4 to 7.

For 2 servings, the ratio would be given by:

O:D = 2 × 4 : 2 × 7 = 8:14

Therefore, we have 8 ounces of oats and 14 ounces of dried fruit.

For 6 servings, the ratio would be given by:

O:D = 6 × 4 : 6 × 7 = 24:48

Therefore, we have 24 ounces of oats and 48 ounces of dried fruit.

For 7 servings, the ratio would be given by:

O:D = 7 × 4 : 7 × 7 = 28:49

Therefore, we have 28 ounces of oats and 49 ounces of dried fruit.

• R(x)=120x

The number of bicycles to break even = 40

Explanation:

Let the number of bikes sold = x

• The operating cost of the store per month = $2400

• Cost Price Per bike = $60

Thus, the total monthly cost for the store:

Next, the average selling price of each bicycle is $120, therefore, the monthly revenue of the store:

The store breaks even when the cost equals its revenue.

We then solve for x:

The store must sell 40 bicycles in order to break even.

The mean of the population can be estimated using the sample mean, which is the average of the data collected from a simple random sample. In this case, the sample data consists of the numbers 13, 15, 14, 16, and 12.

To find the sample mean, we add up all the values in the sample and divide it by the total number of values. In this case, the sum of the sample values is 13 + 15 + 14 + 16 + 12 = 70. Since there are 5 values in the sample, the sample mean is calculated as 70 / 5 = 14.

The sample mean is an estimate of the population mean. It provides information about the central tendency of the population based on the collected sample. In this case, the sample mean of 14 is an estimate of the mean of the entire population from which the sample was taken.

It's important to note that the sample mean may not be exactly equal to the population mean, but it provides a good estimate when the sample is representative of the population and selected through a random sampling method.

Answer:

32

Step-by-step explanation:

We can call the number x. 75% can be expressed as 0.75 so we can write the following equation: 0.75x = 24. Dividing both sides by 0.75 to get rid of the coefficient of x, we get that x = 32.

Answer:

32.

Step-by-step explanation:

Let's say the number we are trying to find is x.

24 = 0.75x

0.75x = 24

x = 24 / 0.75

x = 32

The direction of the greatest increase in heat from the point (2, 5) is in the direction of the vector (-21, -20).

To find the direction of the greatest increase in heat from point (2, 5), we need to find the gradient vector of the temperature function T(x,y) at that point, and then determine the direction in which the gradient vector points.

The gradient vector of T(x,y) is given by:

∇T(x,y) = (∂T/∂x)i + (∂T/∂y)j

where i and j are the unit vectors in the x and y directions, respectively.

Taking the partial derivatives of T(x,y) with respect to x and y, we get:

∂T/∂x = (x² - y²)/(x² + y²)²

∂T/∂y = -2xy/(x² + y²)²

Substituting x = 2 and y = 5, we get:

∂T/∂x = (4 - 25)/(29)² = -21/1681

∂T/∂y = -20/1681

Therefore, the gradient vector of T(x,y) at the point (2, 5) is:

∇T(2,5) = (-21/1681)i - (20/1681)j

The direction of the greatest increase in heat from points (2, 5) is in the direction of the gradient vector. We can normalize the gradient vector to get the unit vector in this direction:

u = (∇T(2,5))/|∇T(2,5)|

where |∇T(2,5)| is the magnitude of the gradient vector, given by:

|∇T(2,5)| = √((-21/1681)² + (-20/1681)²) = sqrt(841)/1681 = 1/41

Thus, the unit vector in the direction of greatest increase in heat from the point (2, 5) is:

u = (-21/1681i - 20/1681j)/(1/41) = -21i - 20j

Therefore, the direction of the greatest increase in heat from points (2, 5) is in the direction of the vector (-21, -20).

Answer:

enlargement ; 2

Step-by-step explanation:

dilation is change in the size of the figure.

in the given scenario, figure's size is increasing so dilation is called enlargement and scale factor must be greater than 1.

scale factor = dimension of new shape / dimension of original shape

let's calculate the difference in terms of boxes of both figures to calculate the scale factor,

scale factor = 6/3

thus, in the given dilation we have enlargement of 2

The colorimeter detects the voltage created when sunlight penetrates the specimen, so the voltage created is exactly proportional to the absorbance of the sample.

When charged electrons (current) are forced through a conducting loop by the weight of an electrical raceway power source, they can perform tasks like lighting a lamp. In a nutshell, voltage equals pressure and is expressed in volts (V).

Here,

The voltage generated by the uv spectrophotometer is inversely proportionate to the amount of light present and linearly proportional to the sample's absorbance.

This indicates that as the sample's absorbance rises, so does the energy the colorimeter generates.

Similar to this, the voltage generated by the colorimeter rises as light strength falls.

The Beer-Lambert Law, which says that a sample's absorbance is directly proportional to its concentration of the absorbing substance and its path length and inversely proportional to incident light intensity, describes this connection.

The colorimeter detects the voltage created when sunlight penetrates the specimen, so the voltage created is exactly proportional to the absorbance of the sample.

Answer:

x = -7, A = 65 degrees

Step-by-step explanation:

[It is important to know that in any triangle, the sum of all three angles is equal to 180 degrees]

Therefore,

x + 72 + x + 51 + 71 = 180

2x + 194 = 180 [collect like terms]

2x = -14 [subtract 194 from both sides]

x = -7 [divide both sides by 2]

To find A, we substitute the value of x into x + 72:

A = (-7) + 72

A = 65 degrees.

(150^3) Divided by 600 equals 5,625.

The (150^3) divided by 600, the value of 150 raised to the power of 3.

150^3 means multiplying 150 by itself three times.

150^3 = 150 * 150 * 150

Calculating the multiplication:

150 * 150 = 22,500

22,500 * 150 = 3,375,000

So, 150 raised to the power of 3 is equal to 3,375,000.

Now, we can divide 3,375,000 by 600 to find the final result.

Step-by-step explanation:

Step 1: Define/explain.

To subtract fractions with different denominators, you must first find the least common denominator (LCM).

You can do this by listing the multiples of each denominator.

Step 2: Solve.

11: 11, 22, 33, 44, 55, 66, 77, 88, 99, 110

2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22

22 is the LCM.

Now, we change the fractions to where they both have denominators of 22.

**REMEMBER: WHICHEVER NUMBER YOU MULTIPLY THE DENOMINATOR BY, YOU MULTIPLY IT BY THE NUMERATOR AS WELL!!**

\(9/11*2/2=18/22\)

\(1/2*11/11=11/22\)

Now, subtract as normal.

\(18/22-11/22=7/22\)

\(7/22 (simplified).\)

Step 3: Conclude.

Therefore, 9/11 - 1/2 = 7/22.
