The money that Salma has to pay if she goes on 6 rides is $40 and if she goes on r rides then she has to pay 10+5r

A solution of an equation is any value of the variable that satisfies the equality, that is, it makes the Left Hand Side (LHS) and the Right Hand Side (RHS) of the equation the same value.

Given here: Admission price=$10 and ride fee= $5

Now if Salma goes for 6 rides than we have

Total fee= 10+5×6

               =$40

And if Salma decides to go for r rides than we can express the total cost as some function of the number of rides r

T(r)=10+5r

Hence, The money that Salma has to pay if she goes on 6 rides is $40 and if she goes on r rides then she has to pay 10+5r

The surface area of the pyramid that has these measures is given as 300 inches square

The surface area of a square pyramid is the sum of the area of the base and the areas of the lateral faces.

The area of the base of the square pyramid is given by the formula for the area of a square:

A = s^2, where s is the length of one side of the square.

In this case, each side of the base measures 10 inches, so the area of the base is:

A = 10^2 = 100 square inches.

The lateral faces of the pyramid are triangles, and the surface area of each lateral face can be found using the formula:

A = (1/2)bh, where b is the length of the base and h is the height.

In this case, the height of each lateral face is 10 inches, and the base is a side of the square base, which measures 10 inches.

So the surface area of each lateral face is:

A = (1/2)(10)(10) = 50 square inches.

Since there are 4 lateral faces on a square pyramid, the total surface area of the lateral faces is 4 * 50 = 200 square inches.

Finally, the surface area of the pyramid is the sum of the surface area of the base and the lateral faces:

A = 100 + 200 = 300 square inches.

Kindly, find the solution on the attachment.

The value of variable m is 4.

Two or more expressions with an Equal sign is called as Equation.

We have to find value of m

As Y is between X and Z it is taken as the midpoint.

The values of XY, YZ and XZ are given as below.

XY=9m−3 , YZ=6m+1 , and XZ=13m+6 .

We need to find the value of the variable m.

If we add xy and yx we get xz.

So by the equation xy+yz=xz we get the value m.

9m-3+6m+1=13m+6

Add the like terms

15m-2=13m+6

15m-13m=2+6

The new average of the students is 25.368.

In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.

Given that, in a group of 24 students attending a party, the average age is 25.3 years.

A 27-year-old student joins the party.

So, the new average is (24×25.3+27)/25

The area of the rectangle is given by the equation A = ( 9x² - 64 ) yards²

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of the rectangle be represented as A

Now , the equation will be

Let the width of the rectangle be W = ( 3x - 8 ) yards

Let the length of the rectangle be L = ( 3x + 8 ) yards

Now , Area of Rectangle = Length x Width

Substituting the values in the equation , we get

Area of Rectangle = ( 3x - 8 ) ( 3x + 8 )

On simplifying the equation , we get

Area of Rectangle = ( 3x )² - ( 8 )²

The inequality that represents the graph is option D: 13x - 3y - 14 < 0.

What is an inequality?

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.

The x-intercept is a = 1.077

The y-intercept is b = -4.677

The equation of line having x-intercept a and y-intercept b is -

x/a + y/b = 1

The equation of line having x-intercept 1.077 and y-intercept -4.677 is -

x/1.077 + y/-4.677 = 1

y/-4.677 = 1 - x/1.077

y = (1 - x/1.077)-4.677

y = -4.677 + 4.677x/1.077

y = -4.677 + 4.342x

Multiply both sides by 3 -

3y = 3(-4.677 + 4.342x)

3y = -14.031 + 13.026x

Now, the line 3y = -14.031 + 13.026x divide the xy-plane in two regions and the region given in the graph is satisfied by the origin.

Also, the line 3y = 14.031 + 13.026x is dotted and not dark ,therefore, the points on the line are not included in the shaded region.

If from the top of a 72 m high vertical cliff, a boat has an angle of depression of 32° then  the distance of boat from the base of the cliff is, 115 m.

An angle is a mathematical term, which we can define, when two straight lines or rays meet at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.

Interior angles:- The inner angle made by the intersection of two polygonal sides.

Exterior angles:- The outer angle made by the intersection of two polygonal sides.

We can use trigonometry to solve for the distance of the boat from the base of the cliff.

Let's call the distance from the base of the cliff to the boat "d".

Then we have:

tan(32°) = 72 / d

Solving for d, we get:

d = 72 / tan(32°)

d = 115.22

Rounding to the nearest whole number, d = 115.

So the boat is 115 meters away from the base of the cliff.

Step-by-step explanation:

The difference between the percentage of Americans who want to be rich and the percentage of Europeans who want to be rich, according to our 95% confidence level, is between (-0.078, -0.101).

The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval. Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test.

In statistics, confidence is another word for probability. 

Given In a random sample of 80 Americans, 36 wished that they were rich. In a random sample of 90 Europeans, 49 wished that they were rich.

Let p₁ = probability of Americans wanting to rich

p₂ = probability of Europeans wanting to rich

p₁ = 36/80 = 0.45

p₂ = 49/90 = 0.54

so CI = (p₁ - p₂) ± z₁(p₁p₂/n₁ + p₁p₂/n₂)

CI = (0.45 - 0.54) ± 1.96(0.0236)(0.243)

CI  = -0.09 ± 0.0112

Case 2

Slope

m = [- 3 - (- 11)] / [1 - (- 7)]

m = 8 / 8

m = 1

Intercept

b = y - m · x

b = 3 - 1 · 7

b = 3 - 7

b = - 4

Equation of the line

y = x - 4

A coterminal angle is an angle that has the same initial point as another angle but has a different measure.

A coterminal angle is an angle that has a different measure in degrees from another angle but the same initial point and direction. It is an angle that is similar to another angle in orientation but may be different in size. Coterminal angles are significant in trigonometry and have numerous uses in physics, engineering, and mathematics.

Angles are frequently measured in degrees in mathematics, and they can have a value between 0 and 360. It's crucial to remember that different measures might be assigned to the same angle based on the starting and finishing points. For instance, a 90-degree angle is one that begins at the positive x-axis and ends at the positive y-axis. Additionally, the same angle can be expressed as 450 degrees, -90 degrees, and so forth. These angles are all regarded as coterminal angles.
