The bar below is 7 inches long and divided into 2 equal parts.

What is the length of one of those parts?

Fill in the blanks in the equation using fractions or mixed numbers

to show the length of one of the parts.

X 7 inches = inches

Answers

Answer:

The length of each part is 3.5 inches.

Step-by-step explanation:

The question states that the bar is 7 inches long, with the two parts being equal lengths.

What you would do to find the length of each bar is doable with simple division. Take 7, and divide it by 2. 2 goes into seven 3 times, which would leave 1. Add a decimal and a zero, bring the zero down, and you get 10. 2 goes into 10 five times, giving you the 5 in 3.5.

1/2×7=3.5 inches is the equation which gives the length of the one of the part of bar.

What is Area of Rectangle?

The area of Rectangle is length times of width.

Given that the bar is 7 inches long and divided into 2 equal parts.

We need to find the length of one of those parts.

We take the whole bar as a whole number.

The two parts of the bar are considered as parts of the bar.

The seven inches is divided equally.

The length of the bar is seven inches.

We need to divide seven by two to get the length of one part.

When seven is divided by the two we get three point five inches which is the length of the one of the part of the bar.

1/2×7=3.5 inches

The equation which gives the length of the one of the part of bar is 1/2×7=3.5 inches.

Hence, 1/2×7=3.5 inches is the equation which gives the length of the one of the part of bar.

If 4x=12 (green balls)
x=3

Now, Red balls = 3x3

2) total = 72 balls

Ratio=3x:4x:5x

3x+4x+5x=72
x=6

Red balls = 3x6

The illustration below shows the graph of y as a function of x.
Complete the following sentences based on the graph of the function.
- As x increases, y _______ (increases/decreases).
- The rate of change for y as a function of x is not __________ (constant/constant), therefore the function is ________ (linear/nonlinear).
- For all values of x, the function value y ___ (≤/≥/=) 0.
- The y-intercept of the graph is the function value y = ____.
- When x = 1, the function value y = ___.

Answers

Answer: As "x" increases "y" *decreases*

y as a function of x is not *constant*

Therefore the function is *nonlinear*

For all values of x, the function value y *≥* 0.

The y intercept of the graph is *8*

x=1 function value of y is *5*

The given function is an exponential function and its qualities are explained below.

What is a logarithmic function?

The opposite of an exponential function is a logarithmic function. A log function and an exponential function both use the same base. An exponent is a logarithm. f(x) = bx is how the exponential function is expressed. The formula for the logarithmic function is f(x) = log base b of x.

As we can observe in the graph.

The illustration below shows the graph of y as a function of x.

Complete the following sentences based on the graph of the function.

- As x increases, y decreases.

- The rate of change for y as a function of x is not constant, therefore the function is nonlinear.

- For all values of x, the function value y > 0.

- The y-intercept of the graph is the function value y = 8.

- When x = 1, the function value y = 5.

Step-by-step explanation:

The intersection of the plane and the solid has

1. Circular cross section.

2. Rectangular cross section.

3. Triangular cross section.
