what expressions are equivalent to 42x - 14y

Answers

Answer:

Step-by-step explanation:

lol u

Answer:

When 42(x + 14y) is simplified:

42(x + 14y)

Expand and remove the brackets. Remember brackets mean to multiply.

42*x

42x

42*14y

588y

42x+588y

Therefore 42x-56 is NOT EQUIVALENT to 42(x + 14y) but is equivalent to 42+588y

The mean of data set A is 42. The mean of data set B is 47. The mean absolute deviation (MAD) of both data sets is 2.5. What is the difference of the means?

Answers

Answer:

the difference of the mean in the case of mean absolute deviation is 2.5

Step-by-step explanation:

The computation of the difference of the mean is shown below:

Difference is of

= B - A

= 47 - 42

= 5

Now the difference of the mean is

= 5 ÷ 2.5

= 2.5

Hence, the difference of the mean in the case of mean absolute deviation is 2.5

The area of a triangle is 36 cm square. Give three possible sets of dimensions for the triangle and explain whether or not you can also give the triangles' side length.

Answers

Answer:

[tex]Base = 6cm[/tex] and [tex]Height = 12cm[/tex]

[tex]Base = 4cm[/tex] and [tex]Height = 18cm[/tex]

[tex]Base = 9cm[/tex] and [tex]Height = 8cm[/tex]

Step-by-step explanation:

Given

Shape: Triangle

[tex]Area = 36cm^2[/tex]

Solving (a): Three possible dimensions

The area of a triangle is:

[tex]Area = 0.5 * Base * Height[/tex]

Let: [tex]Base = 6cm[/tex]

So, we have:

[tex]36= 0.5 * 6* Height[/tex]

[tex]36= 3* Height[/tex]

Solve for Height

[tex]12 = Height[/tex]

[tex]Height = 12[/tex]

So, a possible dimension is: [tex]Base = 6cm[/tex] and [tex]Height = 12cm[/tex]

Let: [tex]Base = 4cm[/tex]

So, we have:

[tex]36= 0.5 * 4* Height[/tex]

[tex]36= 2* Height[/tex]

Solve for Height

[tex]18 = Height[/tex]

[tex]Height = 18[/tex]

So, a possible dimension is: [tex]Base = 4cm[/tex] and [tex]Height = 18cm[/tex]

Let: [tex]Base = 9cm[/tex]

So, we have:

[tex]36= 0.5 * 9* Height[/tex]

[tex]36= 4.5* Height[/tex]

Solve for Height

[tex]8 = Height[/tex]

[tex]Height = 8[/tex]

So, a possible dimension is: [tex]Base = 9cm[/tex] and [tex]Height = 8cm[/tex]

So, the three possible dimensions are:

[tex]Base = 6cm[/tex] and [tex]Height = 12cm[/tex]

[tex]Base = 4cm[/tex] and [tex]Height = 18cm[/tex]

[tex]Base = 9cm[/tex] and [tex]Height = 8cm[/tex]

Solving (b): Can the side lengths be given

We can only determine the base and the height of the triangle, the third side length can not be determined using the available information

Area of Square(leg 6): 36units

Area of square(leg 8): 64units

(3) 100units is the Area

(4) Length of hypotenuse is 10units

Step-by-step explanation:

Square(leg 6): 6*6= 36

Square(leg 8): 8*8=64

The bigger square: 64+36=100

The length of the hypotenuse is 10units because 10*10=100

Complete the equation of this circle:

Answers

The complete equation of the circle graphed is (x - 2)² + (y + 2)² = 9

Determining the equation of the circle graphed

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

The circle

Where, we have

Center = (a, b) = (2, -2)

Radius, r = 3 units

The equation of the circle graphed is represented as

(x - a)² + (y - b)² = r²

So, we have

(x - 2)² + (y + 2)² = 3²

Evaluate

(x - 2)² + (y + 2)² = 9

Hence, the equation is (x - 2)² + (y + 2)² = 9

If Kyle makes a zero on his ELA finals, and it counts for .01% of his 90.8%, how much will Kyle’s grade drop?
—
please help i’m not sure how to do math like this

Answers

Answer:

9.2 %

Step-by-step explanation:

Given: 0 on finals, overall is 90.8, then 0.01%

To find: How much of Kyle’s grade dropped

Solve: First, calculate the percentage you received on the test by dividing your mark by the total marks.

Kyle scored 0 out of 100, then 0/100 = 0 percent.

Secondly, multiply your percentage score on the test by the percentage it is worth of the final grade.

0 × 90.8 = 9.2 %

9.2 % of the final grade
