Answer 1

The value of variable x is 19.20.

How to solve equations ?

Let's find the value of variable x in the equation.

A variable is a number represented with letters in an equation.

Therefore,

x / 6 + 4 / 10 = 3 + 6 / 10

Therefore, let's find the variable x.

10x + 24 / 60 =  30 + 6 / 10

10x + 24 / 60 = 36 / 10

60 × 36 = 10(10x + 24)

2160 = 100x + 240

2160 - 240 = 100x

1920 = 100x

divide both sides by 100

x = 1920 / 100

x = 19.20

Answers

The number of movies rented when the cost for Movies Plus and Movies-To-Go is the same is 10.

What is an equation?

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Let the no. of movies be 'm' and the total cost is 'C'

Movies Plus charges a one-time fee of $20 plus $5 per movie

which is, C = 5m + 20.

Movies-To-Go charges $7 per movie

which is, C = 7m.

Now,  the number of movies rented when the cost for Movies Plus and Movies-To-Go is the same will be when we equate both equations.

What is the confidence interval of an average?

One method of determining the actual population mean is by using a confidence interval for the mean. A confidence interval provides a lower estimate and an upper estimate rather than just the mean.

A confidence interval expresses the degree of uncertainty surrounding a given statistic. A margin of error is frequently used with confidence intervals. It reveals the degree to which you may be certain that the findings of a poll or survey correspond to what you would anticipate discovering if it were possible to poll the complete population. Levels of confidence are inextricably linked to confidence intervals.

if 25% of tolla's sallary is birr 135.75, what is the amount of his full salary?​

Answers

If 25% of Tolla's salary is Birr 135.75, then the full amount of his salary is 4 times this amount, since 25% is one quarter of the total amount.

Therefore, the full amount of Tolla's salary is 4 * Birr 135.75 = Birr 543.

This is the amount of Tolla's full salary.


LOL

To find Tolla's full salary, we can use the following equation:

full salary = 135.75 / 0.25

Plugging in the values, we get:

full salary = 135.75 / 0.25 = 543

So Tolla's full salary is $543.

Find 910−238 . Express your answer as a mixed number in simplest form.

By converting the given improper fraction 910/238 as a mixed number we get the result as 3[tex]\frac{14}{17}[/tex].

What is a mixed number?

A mixed number is one that includes both a whole number and a legal fraction. A number with both an integer (whole number) and a correct fraction is referred to as a mixed number or mixed fraction (a fraction whose numerator is less than its denominator).

Pretzels, peanuts, Cheerios, and of course rice and corn Chex make up this mixture, which is dubbed a "mix." Numerals with both an integer and a fraction included are known as mixed numerals. The term "mixed number" refers to the combination of these two types of numbers.

Given,

910/238 is an improper fraction.

Now by dividing both the numerator and denominator by 14, we get

(910/14)/(238/14)

=65/17

Now, 65/17 can be written as a mixed number as 3[tex]\frac{14}{17}[/tex].

Joe flew his small airplane 1000 km in 4 hours flying with the wind. He flew 700 km against
the wind in 7 hours. Find the rate at which he flew in still air and the rate of the wind.

Answers

Answer:

To solve this problem, we can set up the following system of equations:

Let x be the rate at which Joe flew in still air and y be the rate of the wind.

1000 km / 4 hours = x + y

700 km / 7 hours = x - y

Solving this system of equations using the elimination method, we get:

x + y = 250

x - y = 100

Adding these two equations together, we get 2x = 350, so x = 175 km/hour.

Subtracting the second equation from the first equation, we get 2y = 150, so y = 75 km/hour.

Therefore, the rate at which Joe flew in still air is 175 km/hour and the rate of the wind is 75 km/hour.

The maximum area is 12.25 square feet

How to determine the maximum area

From the question, we have the following parameters that can be used in our computation:

Perimeter = 14 feet

This means that

P = 2(l + w)

So, we have

2(l + w) = 14

Divide by 2

l + w = 7

Make l the subject

l = 7 - w

The area is calculated as

A = lw

So, we have

A = (7 - w)w

Expand

A = 7w - w²

Differentiate and set to 0

7 - 2w = 0

So, we have

w = 3.5

Substitute w = 3.5 in A = (7 - w)w

A = (7 - 3.5) * 3.5

f: (5, 30)

Answers

The point of intersection between the function f(x) and g(x) is x = 4 then, g(x)=18 where option E (4,18) is correct answer.

What is a function?

A function is defined as a relation between a set of inputs having one output each.

We have,

f(x) = ( x + 5 ) ( x - 2 )

g(x) = ( 2x + 1 ) ( x - 2 )

To find the points of intersection between the two functions we must equal the function.

f(x) = g(x)

( x + 5 ) ( x - 2 ) = ( 2x + 1 ) ( x - 2 )

( x - 2 ) gets canceled

x + 5 = 2x + 1

5 - 1 = 2x - x

4 = x

x = 4

This means that at x =4 the function f(x) and g(x) intersect.

we can see that at x = 4 both the functions have the same value.

f(x) = ( x + 5 ) ( x - 2 ) = ( 4 + 5 ) ( 4 - 2 ) = 9 x 2

f(x) = 18

g(x) = ( 2x + 1 ) ( x - 2 ) = ( 2 x 4 + 1 ) ( 4 - 2 ) = ( 8 + 1 ) ( 4 - 2 )

     = 9 x 2

g(x) = 18

Thus the point of intersection between the function f(x) and g(x) is x = 4 then, g(x) =18 where option E (4,18) is correct answer.

Question 7

Answers

If the diameter of a small red beachball is 8 inches, then the cone with the same radius and a height of a 8 inches would fit into the beachball 1/2 times and the volume of the cone would be about 536 in^3.

What is cone and its formula?They develop as a result of lava pieces being blown into the air by ferocious eruptions, solidifying, and then falling as cinders surrounding the volcanic vent. These cinders, which are typically the size of pebbles, are packed with numerous small bubbles that the lava captured as it solidified. The height of a cinder cone can range from tens to hundreds of metres.A cone has no edges and just one face, which is its round base. A cone only has one vertex or apex point. The cone has a volume of 13 r2h. The cone's total surface area is equal to r(l + r). The cone's slant height is (r2+h2).A cone has a vertex that is not on the base and a single circular base.

Explanation :

If the diameter of a small red beachball is 8 inches, then the cone with the same radius and a height of a 8 inches would fit into the beachball 1/2 times, because Centre radius will reduced to point when it reaches its full height.

The volume of the cone would be about 536 in^3.

Volume of a cone = 1/3 π [tex]r^{2}[/tex] *h

                              = 1/3 x π x [tex]8^{2}[/tex] x 8 = 536

Answer:

two134

Step-by-step explanation:

You want to know how many times the volume of a cone 8 inches in diameter and 8 inches high will fit into the volume of a beachball that is 8 inches in diameter, and you want the approximate volume of the cone.

Sphere volume

The equation for the volume of a sphere based on its diameter is ...

  V = π/6d³

Cone volume

The equation for the volume of a cone is usually written ...

  V = 1/3πr²h

For the cone in this problem, with both diameter and height equal to that of the sphere, we can rewrite the volume equation as ...

  V = 1/3π(d/2)²·d = π/12d³ . . . . . . where d=8 inches, the sphere diameter

Volume ratio

Then the ratio of the sphere's volume to that of the cone is ...

  Vs/Vc = ((π/6)d³)/((π/12)d³) = 12/6 = 2

The volume of the cone will fit into the volume of the sphere two (2) times.

Numerical volume value

The volume of the cone is ...

  V = (π/12)8³ = 128π/3 ≈ 134 . . . . cubic inches

The cone's volume is about 134 in³.

Additional comment

Note that we have taken the wording "with the same radius" to mean that the radius of the cone is the same as the radius of the sphere.

Alternatively, it could mean the radius of the cone is the same as the dimension given for the diameter of the sphere. In that case, the volume of the cone is 4 times as great, so its volume of 536 in^3 will fit into the sphere 1/2 times.

What are coordinate points?

A specific point on a grid referred to as a coordinate plane can be located using coordinates, which are two numbers. In a plane, a point is known to have specific coordinates. The coordinates are the ordered pairs of numbers (x, y) that describe the location of any point on a plane. In our everyday lives, we use coordinates for things like map location, classroom seating, and more.

a) Extending point L towards the y-axis, we see that it corresponds to the given coordinate, i.e., (0,b). Therefore the y coordinate is b.

Next, extending the point L towards the x-axis, we see that the point lands somewhere between the distance 'a' from the origin. As the height is 'b', and as the trapeziums are identical, we can say that the extended point of L lands at a point that is 'b' distance from 'a'. Hence the x coordinate is a-b.

Hence, the coordinates of point L are (a-b,b).

b) Given M(9,9) and N(15,15).

Extending the point M towards the x-axis, we get that it coincides with the point 'a', therefore we get the value of a=9.

Now extending point N towards the x-axis, we get that it lands at a distance of 15 from the origin. We got the value of a=9, so the remaining distance between the point (9,0) and (15,0) is 6 units.

Extending the point (9,0) upwards, we see that it cuts the uppermost trapezium giving us the distance of the trapezium excluding the small triangle formed. Now taking the same information, if we cut the bottom-most trapezium, we see that it cuts at point (6,0).

Now we know the height of the trapezium is 'b'. So, we get b=9-6 (as 9 is the distance of the entire trapezium, and 6 is from the above calculations).
We get b=3.

Hence we got the value of 'a'=9 and 'b'=3.
