The value of x in the equation  2.14x - 12.18 = 5.76 is  8.38.

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.

Given, we have to solve for x or find the value of x in the equation

2.14x - 12.18 = 5.76.

2,14x = 5.76 + 12.18.

2.14x = 17.94.

x = (17.94/2.14).

Final answer:

The sum of 8/15 and 2/5 is 14/15, which is closer to 1 than to 0 or 1/2 after finding a common denominator and adding the fractions.

Explanation:

To determine whether 8/15 + 2/5 is closer to 0, 1/2, or 1, you need to first find a common denominator for the fractions. The least common denominator for 15 and 5 is 15. You can then rewrite the second fraction, 2/5, with 15 as the denominator by multiplying both the numerator and denominator by 3, which gives you 6/15.

Now add the two fractions:

8/15 + 6/15 = 14/15

This sum is very close to 1, but still less than 1. Therefore, 14/15 is closest to 1.

To conceptualize this, you can think about the fractions in terms of division: 8 divided by 15 is a bit more than half, and 2 divided by 5 is exactly 0.4, which is also slightly less than half. Their sum is thus nearly a whole but not quite there, clearly indicating it's closer to 1 than to 0 or 1/2.

Answer:

110.1

Step-by-step explanation:

So, we just need to figure out 734% of 15.

734% can be written as 734/100.

734*15=11010.

11010/100 = 110.1

Step-by-step explanation:

In parallelogram RECT is a rectangle,

EC = x + y , RT = 2x - y, RE = 2x + y and TC = 3x - 3

To find, the values of the variable = ?

∵ The opposite sides are equal.

∴ RE = TC and RT = EC

2x + y = 3x - 3

⇒ x - y = 3                   .......... (1)

Also,

2x - y = x + y

⇒ x - 2y = 0               .......... (2)      

Subtracting (1) from (2), we get

∴ x - y - (x - 2y ) = 3 - 0

⇒ x - y - x + 2y = 3

⇒ y = 3

Put y = 3 in equation (1), we get

x - 3 = 3  

⇒ x = 3 + 3 = 6

∴ x = 6 and y = 3

Thus, the values of the variable are 3 and 6.

Answer:

  f(3) = g(3)

Step-by-step explanation:

The graph shows f(3) = 6, and it shows g(3) = 6. Then ...

  f(3) = g(3)

To determine if two functions f and g are equal at certain points, one must refer to their definitions or graphs. If f(x) and g(x) are defined as x², they are the same function as they produce identical outputs for any numerical input.

The student's question pertains to function comparison and the evaluation of these functions at specific points. The statement "f(6) = g(3)" implies that the value of the function f when x is 6 is equal to the value of function g when x is 3.

The answer to the question will rely on the specific definitions or graphical representations of the functions f and g, provided in the original question or accompanying materials.

For the functions defined by f(x) = x² and g(s) = s², f and g are indeed the same function since they both return the square of their input, regardless of the variable used to represent that input.

Since both function names are simply placeholders for the operation being performed (squaring), f and g yield the same output for any identical numeric input.

Based on the examples in the reference information, we can see that two different functions could have the same graph if they result in the same set of points on a Cartesian plane. This would make them the same function in the context of their graphical representation.

Conviction of DUI results in increased fines and jail time if aggravating factors such as high alcohol levels or prior offenses are present.

If you are convicted of DUI (driving under the influence), your fine and jail time will typically be increased if certain aggravating factors are present. These can include having a high blood alcohol content, previous DUI convictions, causing an accident while DUI, especially if injury or death occurred, having minors in the vehicle, and others. The penalties are enhanced due to the increased risk and harm these factors represent.

Answer:

Actual mean: 223 pages

Predicted mean / estimate: 225 pages

Explanation below

Step-by-step explanation:

Mean = total amount ÷ # of numbers

155 + 214 + 312 + 198  + 200 + 170 + 250 + 260 + 215 + 256

Add

2,230

# of numbers = 10

2,230 ÷ 10 = 223

The exact mean is 223

If I were to predict the mean, I would say that a good estimation would be around 225, because I see that the highest number in the data set is 312, and the lowest is 155. If 312 is rounded down to 300, and 155 is rounded down to 150, the number exactly in the middle of 300 and 150 is 225.

It is a function

A function is a relation between two sets that associates to every element of a first, called set A, one and only one element of the second set, called set B. In other words, we can't have any element of the set A assigned to more than one element in the set B. Put another way, we can't have repeated elements of the first set. In this problem we have a relation given by the table:

[tex]\begin{array}{cc}x & y\\5 & -2\\7 & -2\\9 & -2\end{array}[/tex]

So the assignation is as follows:

[tex]5 \rightarrow -2 \\ \\ 7 \rightarrow -2 \\ \\ 9 \rightarrow-2[/tex]

As you can see every element of the set A (set x) is assigned to the same element in the set B (set y) but we have no repeated element in the first set, so this is a function.

The cup can hold 235.5 cubic cm of popcorn.

Step-by-step explanation:

Given:

A cone shaped popcorn cup has a radius of 5 cm and a height of 9cm.

Use 3.14 as an approximation for pi.

Now, to find cubic cm of popcorn the cup can hold.

Radius ( r ) = 5 cm.

Height ( h ) = 9 cm.

π = 3.14 ( as per question ).

So, to get the cubic cm of popcorn the cup can hold we put formula of volume:

[tex]Volume = \pi r^2\frac{h}{3}[/tex]

[tex]Volume=3.14\times 5^2\times \frac{9}{3}[/tex]

[tex]Volume=3.14\times 25\times 3[/tex]

[tex]Volume=235.5\ cubic\ cm.[/tex]

Therefore, the cup can hold 235.5 cubic cm of popcorn.

Answer:

55 square feet

Step-by-step explanation:

We can represent the area as a sum of two rectangles.

A = 8 * 5 + 5 * 3 = 40 + 15 = 55 square feet

Answer:

Step-by-step explanation:

Area of rectangle at top

length =5ft; breadth = 3 ft

Area = 5*3 = 15 sq.ft

Area of rectangle at bottom

length = 8ft ; breadth =8-3 = 5 feet

Area = 8*5 = 40 sq.ft

Area of the figure = 15 + 40 = 55 sq.ft

The transformer is 27.5 ft above the ground.

Solution:

The given image is like a triangle.

Angle 'L' represents the triangle is right triangle.

Use Pythagoras theorem to find the answer.

Base of the triangle = 12 ft

Hypotenuse of the triangle = 30 ft

Height of the triangle = x

Using Pythagoras theorem,

[tex]\text{Base} $^{2}+$ Height $^{2}=$ Hypotenuse $^{2}$[/tex]

[tex]12^2+x^2=30^2[/tex]

[tex]144+x^2=900[/tex]

Subtract 144  on both sides of the equation.

[tex]x^2=900-144[/tex]

[tex]x^2=756[/tex]

Taking square root on both sides.

[tex]x=27.5[/tex]

Hence the transformer is 27.5 ft above the ground.
