Answer:

  b.  9 inches

Step-by-step explanation:

The area of a triangle is given by ...

  A = 1/2bh

Solving for h, we get ...

  h = 2A/b

  h = 2(36 in²)/(8 in) = 72/8 in

  h = 9 in

The height of the triangle is 9 inches.

7th grade math help me please :))
KatRina [158]

Answer:

40

Step-by-step explanation:

s = 2;

h = 4

Surface area = 2s² + 4sh

                     = 2*2² + 4 * 2 * 4

                    = 2 *4 + 32

                    = 8 + 32

                  = 40 sq. units

What are the slope and the y-intercept of the linear function that is represented by the graph?
Tatiana [17]

Answer:

In the slope-intercept form you use the slope of the line and the y-intercept to express the linear function.

y=mx+b

Where m is the slope and b is the y-intercept.

Example

Graph the equation

y−2x=1

rewrite in slope-intercept form

y=2x+1

Identify the slope and the y-intercept

m = 2 and b = 1

Plot the point corresponding to the y-intercept, (0,1)

The m-value, the slope, tells us that for each step to the right on the x-axis we move 2 steps upwards on the y-axis (since m = 2)

Step-by-step explanation:

You can check to see that the line you've drawn is the correct one by substituting the coordinates of the second point into the original equation. If the equation holds true than the second point is correct.

Our second point = (1, 3)

y−2x=1

3−2⋅1=3−2=1

Our second point is a solution to the equation i.e. the line we drew is correct.

A line that passes through the origin has a y-intersect of zero, b = 0, and represents a direct variation.

y=mx

In a direct variation the nonzero number m is called the constant of variation.

You can name a function, f by using the function notion

f(x)=mx+b

f(x) is another name for y and is read as "the value of f at x" or "f of x". You can use other letters than f to name functions.

A group of functions that have similar characteristics are called a family of functions. All functions that can be written on the form f(x) = mx + b belong to the family of linear functions.

The most basic function in a family of functions is called the parent function. The parent function of all linear functions is

f(x)=x

On a piece of paper, draw a box plot to represent the data below. Then determine which answer choice matches the box plot you dr
Bond [772]

Answer:

The whisker box-plot that represents this data is:

Option: C

Step-by-step explanation:

We have the set of data points as:

11, 12, 15, 16, 17, 19, 22, 24, 29, 33, 38

From these data points we could observe that the:

Minimum value of whisker-box plot is: 11

Maximum value of whisker-box plot is: 38

The median is the central tendency of the data and the middle line in the box-plot represents the median.

Hence, here we have:

Median i.e. Q_2=19

Also, we know that the minimum value of the box represents the lower quartile and it is the median of the lower set of the data and is:

Also lower set of data is:

11, 12, 15, 16, 17

and the middle value of data is: 15

Hence,

Lower quartile i.e. Q_1=15

Similarly,

the minimum value of the box represents the upper quartile and it is the median of the upper set of the data.

The upper set of data is:

22,24,29,33,38

and median of the uppers set of data is 29.

Hence,

Upper quartile i..e Q_3=29.

Option: C is the correct answer.
