The difference of Janelle's height and 9 is 65
Use the variable j to represent Janelle's height.

If the Great games company sells 9/20 of its games through its online stores, then the percentage of the games are sold online is 45%

The fraction of games sells through the online store = 9/20

Here we have to convert the simple fraction to the percentage

Simple fraction is a fraction that consist of whole number numerator and denominator. The top term in the simple fraction is called the numerator and bottom term is called denominator

The percentage is defined as the number that is expressed as the fraction of 100. It is represented by the percentage sign "%"

To convert  simple fraction to percentage, multiply the simple fraction by 100

The percent of games are sold online = (9/20)×100

= 45%

Hence, if the great games company sells 9/20 of its games through its online stores, then the percentage of the games are sold online is 45%.

Answer:

Yes, you have to distribute.

Step-by-step explanation:

2+5(x+3)-3(x-4)=x+2(2x+4)

2+5x+15-3x+12=2(2x+4)

Add the Numbers

2+5x-3x=2(2x+4)

Combine Like Terms, Then you can rearrange the terms for simplification. You should end up with an exation looking like this:

2x+29=5x+8

Subtract 29 from both sides. Simplify, then subtract 5x from both sides.
2x-5x=5x-21-5x
Simplify, then Divide both sides by the same factor. Simplify once more then you should have
x=7

Hello!

So, we are given the following to solve:

[tex]\frac{1}{2}- \frac{9}{4}x=- \frac{2}{3}[/tex]

To solve this, subtract  [tex]\frac{1}{2}[/tex] from both sides.

[tex]\frac{1}{2} -\frac{9}{4}x- \frac{1}{2} =-\frac{2}{3} -\frac{1}{2}[/tex]

Simplify.

[tex]-\frac{9}{4}x= -\frac{7}{6}[/tex]

Multiply both sides by 4.

[tex]4(-\frac{9}{4}x)=4(-\frac{7}{6})[/tex]

Simplify.

[tex]-9x=-\frac{14}{3}[/tex]

Divide both sides by -9.

[tex]\frac{-9x}{-9}= \frac{-14/3}{-9}[/tex]

Finally, simplify.

The value of KM is 20

A line, ray, line segment, or point that cuts a line segment at its center and divides it into two equal portions is known as a segment bisector. A segment is a section of a line with definite ends, which is also how the word segment is sometimes used. Any object or line is divided into two equal halves when it is bisected. Consequently, when two line segments cut or bisect each other at a location that divides the lines into equal halves, this is known as a segment bisector.

Given that : The line q bisects KM at point V, KV = 2.5z and VM = 5z - 10

the line q bisects KM at point V so KV = VM

KV = 2.5z

VM = 5z - 10

2.5z= 5z - 10

10 = 2.5z

4 = z

Now put the value of 4 in KV and VM

KV = 2.5(4)

VM = 5(4) - 10

KV + 10

VM = 10

KM = KV + VM
KM = 10 + 10

= 20

Triangle RST is rotated 180° about the origin, and then translated up 3 units.  Then , ΔRST ≅ ΔBAC

We know that  To rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y).

Thus, The coordinates of triangle RST becomes

R (1,1) → R'(-1,-1)

S (3,4) → S'(-3,-4)

T(-5,0) → T'(5,0)

Also ΔRST after rotation is translated up 3 units. , so we apply the rule (x,y)→(x,y+3)

R'(-1,-1)→R"(-1,-1+3)=R"(-1,2)→ B

S'(-3,-4) → S"(-3,-4+3) = R"(-3,-1) → A

C'(-5,0) → C"(-5,0+3) → C"(-5,3) → C

As rotation and translation both are rigid transformation that maps only congruent figures.

1 to the 10th power is 1.

There are 8 tenths in 4/5, There are five fifths in 1/10, there are 2 tenths in 1/5, there are 25 fifths in 5.

The digit that follows the decimal has the place value of tenth. It stands for the digit's 1/10 position.

The fifth of a number is obtained by multiplying five occurrences of the number n together: n5 = n n n n. A number's fourth power or its square by its cube can likewise be used to create fifth powers.

a) Given 4/5, multiply the numerator and denominator by 2 to obtain the tenths. We get =4/5 2/2 =8/10 =8(1/10). Similarly, in 1/5, calculate the tenths in 1/5.

The reflection of a coordinate about the y = x  will interchange the coordinate thus the reflection of points A(0, -3), B(2, 2), C(5,0) will be A'(-3,0)B'(2,2)C',(0,5).

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

Reflection is a mirror image of a graph about any axis.

It is known that,

If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).

Therefore,

A(0, -3) → A'(-3,0)

B(2, 2) → B'(2,2)

C(5,0) →C'(0,5)

Hence "The reflection of a coordinate about the y = x  will interchange the coordinate thus the reflection of points A(0, -3), B(2, 2), C(5,0) will be A'(-3,0)B'(2,2)C',(0,5)".

A measure of the probability that the sample's average IQ is below 987 is 44.70 %.

The Z-score quantifies the discrepancy between a given value and the standard deviation. The Z-score, also known as the standard score, indicates how many standard deviations a specific data point deviates from the mean.

The Z-standard score's deviation measure, which the p-value is, can be regarded of as a percentile expression. So they do have p-values.

Given: IQ scores are frequently described as having a normal distribution with a mean of 100.0 and a standard deviation of 15.0. A sample of 57 persons is chosen at random.

Z-score = (X- μ)/σ

             = (98-100)/15

             = -0.1333

Mandy must to walk a distance of 24.73 units towards Mark.

Given:

Mark is standing at 35th Street and 21st Avenue, so his location can be determined using the coordinates (35,21)

Mandy is positioned at 59th Street and 15th Avenue, hence her position's coordinates are as follows: (59,15).

We must now determine the distance Mandy must travel if Mark stays where he is and walks to meet him.

D = [tex]\sqrt{(x_{2}-x_{1} )^{2} + (y_{2} -y_{1})^{2} } }[/tex]

Here,

(x₁, y₁) =  (35, 21)

The quadrilateral named D, H, and E will be the scaled copies of the unlabeled rectangle.

A quadrilateral may be defined as a closed figure having four sides whereas a rectangle is a type of quadrilateral which has four sides in which any two sides are equal and the other two sides are also equal. The interior angles are 90°. The scale factor may be defined as the ratio of two dimensions such that one figure is large, and another is small. The scale factor is done due to the unpractical measurement of any figure. For example, if a figure is a scale copy of the scale factor of 6/2 it means 2 is converted into 6. Now, from the question If any figure is a scaled copy, then all dimensions must be enlarged with the same factor it means length and width both must be enlarged with the same factor. So, the unlabeled rectangle has 4 grid lengths and 2 grid widths. In H length is 8 grids and width are 4 which is the multiplication of 2 by 4 and 2. Quadrilateral D and E also follow the same.
