An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

Given that, a man weighs 95 kg and starts an exercise and eating programme to lose weight.

Let the number of weeks be x.

Now, the expression is 95-0.4x

Here, x=36

95-0.4×36

= 95-14.4

Answer:

There are 14 pizza rolls and 2 mini hot dogs in the combination meal.

Step-by-step explanation:

From the question, we have the following parameters

Pizza roll = 55 calories each

Mini hotdog = 70 calories each

Combination meal = 910 calories in total

Let the pizza roll be x and the mini hotdog be y

So, we have

55x + 70y = 910

x = 12 + y

Make x the subject in x = 12 + y

x = 12 + y

Substitute x = 12 + y in 55x + 70y = 910

55(12 + y) + 70y = 910

Evaluate

660 + 55y + 70y = 910

So, we have

125y = 250

This gives

y = 2

Recall that

x = 12 + y

So, we have

x = 12 + 2

x = 14

Hence, there are 14 pizza rolls and 2 mini hot dogs

The perimeter of an equilateral triangle is equal to three times the length of the side.  Perimeter = 33 cm and Area =  30.58 cm^2 (√30.58 cm^2)

Perimeter of an equilateral triangle = 3 x side  

=> 3 x 11 cm = 33 cm  

Area of an equilateral triangle = (√3/4) x (side^2)  

=> (√3/4) x (11 cm^2)  

=> (√3/4) x (121 cm^2)  

=> 30.58 cm^2  

=> √30.58 cm^2

The perimeter of an equilateral triangle is equal to three times the length of the side. Therefore, an equilateral triangle with a height of 11 cm will have a perimeter of 33 cm (3 x 11 cm). The area of an equilateral triangle can be calculated using the equation (√3/4) x (side^2). In this case, the area of the triangle is 30.58 cm^2 ((√3/4) x (11 cm^2)). This can be simplified to √30.58 cm^2 in its simplest radical form.

The function f(a+1) is equal to option C. 3a + 4.

Given function:

f(x) = 3x + 1

We have to find f(a+1).

For this purpose, we will take x = a+1 and

substitute it in the function f(x) = 3x+1:

f(x) = 3x + 1

f(a+1) = 3(a+1) +1

f(a+1) = 3(a) + 3(1) +1

Speed = 7.7miles/2.2hours = 3.5miles/hour

In physics, the average speed is defined as the ratio of distance traveled during a certain time period.

Distance/Time = Speed

If the problem stated that the two groups’ average speeds are equal,

Mark’s Group Speed Equals Sally’s Group Speed

The problem now suggests that the time is likewise equal. That means Sally’s group took t = 4.7 – 2.5 = 2.2 hours to travel the remaining 7.7 miles.

That implies that the speed is,

You want to build a structure with a length of 5 m, where the proportions of other dimensions are conserved. Estimate the scale factor, 10 cm / 5 m = 0.02 .

The scale factor is a number that represents the ratio of the measurements of two similar figures, such as geometric shapes or maps. To find the scale factor, you can compare corresponding side lengths or angles of the two figures. The scale factor is the ratio of the length of a side in one figure to the corresponding side in the other figure. You can also find the scale factor by taking the square root of the ratio of the areas or the ratio of the volumes of the two similar figures.

Once you have the scale factor, you can use it to find the missing measurements of a similar figure by multiplying any measurement of one figure by the scale factor. In summary, the scale factor is a numerical value that allows to relate the measurements of two similar figures.

The four ways to find the midpoint of a line segment are using the Midpoint Formula, using the Distance Formula, using a Graph, and using a Ruler.

Using the Midpoint Formula:

This method involves using the midpoint formula, which is (x1 + x2)/2, (y1 + y2)/2. This formula gives the coordinates of the midpoint when the coordinates of the two endpoints of the line segment are known.

Using the Distance Formula:

This method involves using the distance formula to find the distance between the two endpoints of the line segment and then dividing the distance by 2. The midpoint will be located at the point that is half the distance from each endpoint.

Using a Graph:

This method involves plotting the two endpoints of the line segment on a graph and then drawing a line segment connecting the two points. The midpoint of the line segment will be located at the point where the line segment is bisected.

Using a Ruler:

Answer: To get another turn, Sydney's score must be greater than 1. Therefore, to find the lowest number that Sydney can roll to get another turn, we need to find the smallest number that, when multiplied by the fraction on the card, will give a result greater than 1.

It's not mentioned which fraction card Sydney drew, so we can assume any fraction.

Let's assume the fraction card is labeled 1/4.

To get another turn, Sydney's score must be greater than 1. Therefore, we need to find the smallest number that, when multiplied by 1/4, will give a result greater than 1.

1/4 * x >1

x > 4

so the smallest number that Sydney can roll to get another turn is 5.

It should be noted that this is assuming that the fraction card is labeled 1/4 , if the fraction card is labeled with any other fraction the answer would be different.

The scaled copy is bigger that means each side is bigger than the original one or the factor is grater tan 1 as  final length(bigger)/ original > 1

In mathematics, a dilation is the enlargement or contraction of a figure by a predetermined scale factor, k, at or around a center of dilation. It is a transformation style that yields comparable figures.

Depending on the scale factor, the original figure will either enlarge or decrease in size. Scaling, also known as dilations, has no impact on how angles are measured.

The original and updated figures' angles will not change because the size has not changed but the shape has. Preimage and image are two terms that can be used to describe the first and new figures, respectively.

The original figure's vertices are identified with capital letters, such as B, to make it easier to identify between two similar figures.

A line can be represented in the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.

Given that m = −72 and the y-intercept is 12, we can represent the line as y = −72x + 12

We are also given that the point (x, 5) lies on the line. So we can substitute the x and y values of the point into the equation of the line to find the value of x.

y = −72x + 12

5 = −72x + 12

-7 = -72x

x = 7/72

So the value of x is 7/72.

We can also get this by solving the equation of the line for x.

y = -72x + 12

y - 12 = -72x

(y - 12)/-72 = x

x = (y - 12)/-72

So for any point (x, y) on the line, the value of x can be obtained by substituting y and the slope-intercept form equation.
