Step-by-step explanation:

Patrice needs to consume more than 1200 calories, but less than 1600 calories.

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

Given, Patrice is trying a low-calorie diet. She would like to keep her calories consumed between the levels shown in the following compound inequality: 2450 < 2x + 50 and 2x + 50 < 3250.

From the first inequality

2450 < 2x + 50

2400 < 2x

x > 1200

From the second inequality

2x + 50 < 3250.

2x < 3200

x < 1600

Therefore, x > 1200 and x < 1600; Patrice needs to consume more than 1200 calories, but less than 1600 calories.

because I added the 98,4,100,10

Answer:

This question is based on the concept of mean. Therefore, the scores for the four games were 97, 98, 98, 107.

Given:

Sue played four games of golf. For these games her modal score was 98 and her mean score was 100. Her range of scores was 10.

According to the question,

If the modal score is 98 then, there must be two games where she scored 98.

The mean is the total of all of her scores divided by the number of games,

We get,

98+98+x+y=400

x+y= 204

As it is given that, the range is 10 and x is the lowest and y is the highest we can say that:

As we know that, her range of scores was 10,

97+10= 107

Therefore, the scores for the four games were 97, 98, 98, 107.

On solving the provided question, we can say that by equation so he has to play 10 games at each arcade,  to spend the same amount of money at each arcade

A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.

the equation that we can create here is

Kabir paid an entrance of $5 plus an additional 0.75 per game at a local arcade.

he and a friend went to another arcade where kabir paid $1.25 per game, but there was no entrance fee

let kabir played 10 games.

then at arcade 1 he spends $5 + (10*0.75) = 5 + 7.5 = $12.5

now at arcade 2 = 12.5/1.25 = 10 to spend the same amount of money at each arcade

so he has to play 10 games at each arcade,  to spend the same amount of money at each arcade

Answer:

C. No; you would need to know that each pair of diagonals is perpendicular.

Step-by-step explanation:

It is not sufficient to establish that MNOP and TQRS are congruent parallelograms given that MO=TR and NP=QS. Parallelograms that are congruent have the same size and form. A common method for demonstrating that two parallelograms are congruent is to use one of the following criteria:

SSS (Side-Side-Side) : If all three pairs of corresponding sides are congruent.

SAS (Side-Angle-Side): If two pairs of corresponding sides and the included angle are congruent

ASA (Angle-Side-Angle): If two pairs of corresponding angles and the included side are congruent

HL (Hypotenuse-Leg): If the hypotenuse and one leg of one right triangle are congruent to the hypotenuse and one leg of another right triangle

CPCTC (Corresponding parts of Congruent Triangles are Congruent)

Given that we only know that MO=TR and NP=QS, we do not have enough information to prove that the parallelograms are congruent. It is missing information about the angles and the diagonals of the parallelograms.

In addition to that, we need to know that the diagonals of the parallelograms bisect each other. If this is the case, then we can use HL to prove that the parallelograms are congruent.

The given differential equation with variable separation will be cosy = -1/2 sin2x + C.

A differential equation in mathematics is an equation that connects the derivatives of one or more unknown functions.

Applications often involve functions that reflect physical quantities, derivatives that depict the rates at which those values change, and a differential equation that establishes a connection between the three.

Due to the prevalence of these relationships, differential equations are widely used in many fields, including engineering, physics, economics, and biology.

So, we have the differential equation:

csc(y) dx + sec2(x) dy = 0

We, are aware that:
csc(y) = 1/ siny

sec(x) = 1/ cosx

We can also write it:

dx/siny = dy/cos2x

Cross multiplication with variable separation:

siny dy = cos2x dx

Differentiate:
cosy = -1/2 sin2x + C

As a result, the given differential equation with variable separation will be

cosy = -1/2 sin2x + C.

Therefore, the given differential equation with variable separation will be cosy = -1/2 sin2x + C.

What does the slope intercept form mean?

The formula for a straight line, written as y = mx + b, where m denotes the line's slope and b its y-intercept. We can see that the y-intercept of the line in our equation, y = 7 x + 4, is 4.

                   In the slope-intercept form, the equation for the line is expressed as follows: y = mx + b, where m denotes the slope and b the y-intercept. We can observe that the line's slope is 3 from our equation, y = 3 x + 5.

All lines passing thru the origin should have a slope of y = mx + c

In this case, since the slope is 1/7 ,  the line will be  y = 1/7x

Thus, it could observe which is the only point  that satisfies this equation of the line out of all the points.

For choice "E" when x= 7  and y = 14  m = 1/7 and put the value in y = mx + c  it will give 14 = 2 , which is wrong.

Answer: havles and half have a difference of the amount of halves

Step-by-step explanation:  such as one half is just 1 havles, but 2 halves you have 2 a halfs.

If we changed the 2 to a 5 in the domain restriction, the graph would become a line that extends infinitely in both directions.

Domain restriction in mathematics is the process of restricting the possible values of a variable to a certain range or subset of values. This can be done by limiting the domain of a function or equation. In general, domain restriction involves identifying a range of values for which the function or equation is valid and then discarding any values that do not fall within that range. For example, if a function was defined for all real numbers, but the domain was restricted to only positive values, then the function would no longer be valid for negative numbers.

If we changed the 2 to a 5 in the domain restriction, the graph would become a line that extends infinitely in both directions. This is because the equation y = 2x + 5 is equivalent to y = 5x, which is a line with a slope of 5 and a y-intercept of 5.

For our pyramid, this gives us the volume of the pyramid (1/3)x²y.

Let the length of base be x and height be y

Volume of pyramid = [tex]\frac{1}{3}[/tex]× l× b× h

The volume of a right rectangular prism is found by finding the area of the base and multiplying by the height.  This is because there are "layers" of the base from the bottom to the top, making the height the number of "layers."

However, in a pyramid, the shape comes to a point.  This makes the volume of a pyramid 1/3 of that of the corresponding prism.

For our pyramid, the area of the base would be x(x) = x².  

There are y layers of this base, so this would be x²y.  

Since it is a pyramid, this gives us the volume of the pyramid (1/3)x²y.

Answer:

f(x) = (1/5)x - (2/5)

Step-by-step explanation:

The linear function can be written in the form of f(x) = mx + b, where m is the slope and b is the y-intercept.

To find the rule for the linear function when x=-10, y=-1, when x=0, y=1 and when x=10, y=3, we can use the two points method.

We can start by finding the slope (m) of the function using the following formula:

m = (y2 - y1) / (x2 - x1)

Where (x1, y1) and (x2, y2) are two points on the line.

Using the point (-10, -1) and (10, 3) we get:

m = (3 - (-1)) / (10 - (-10)) = 4/20 = 1/5

Now that we know the slope, we can use the point-slope form of the equation of a line to find the equation of the line:

y - y1 = m(x - x1)

Plug in one of the points and the slope that we found:

y - (-1) = (1/5)(x - (-10))

y = (1/5)x - (2/5)

So the equation of the linear function is f(x) = (1/5)x - (2/5)

This is the rule of the linear function when x=-10, y=-1, when x=0, y=1 and when x=10, y=3.

The sum of all the elements of set S is -(220/7).

To express the function (x^2+5x +y)/(x^2+7x - 44) as a quotient of two linear functions, the denominator must be a factor of the numerator. In other words, (x^2+7x - 44) must divide (x^2+5x +y) without leaving any remainder. To find the sum of the elements of S, we can set the numerator equal to the denominator multiplied by a constant and solve for y.

x^2+5x +y = c(x^2+7x - 44)

The constant c is a scalar value.

x^2+5x +y = cx^2 +7cx - 44c

we can now equate the coefficients of x^2 and x.

1 = c

and, 5 = 7c

now we can solve for c:

c = 5/7

Now we can substitute the value of c back into the equation:

x^2+5x +y = (5/7)(x^2+7x - 44)

=> x^2+5x +y = (5/7)x^2 + (35/7)x - (220/7)
