Answer:

Option B is correct

m = 0.5 is the solution to the equation

Step-by-step explanation:

Given the equation:

3.6m-2.7= -1.8m

Add 2.7 to both sides, we have;

3.6m-2.7+2.7= -1.8m+2.7

Simplify:

3.6m = -1.8m+2.7

Add 1.8 m to both sides we have;

5.4m =2.7

Divide both sides by 5.4 we have;

m = \frac{1}{2} = 0.5

⇒m = 0.5

Therefore, the solution for the given equation is, 0.5

Answer:

The value of m is 0.5

Option B is correct

Step-by-step explanation:

Given equation

3.6m-2.7=-1.8m

On solving

Firstly we move the 1.8 m to left hand side in the equation

3.6m+1.8m=2.7

Now, On adding in left hand side

5.4m=2.7

On dividing of 2.7 by 5.4

m=\dfrac{2.7}{5.4}

m = 0.5

Hence, The value of m is 0.5

Complete the statement using always, sometimes, or never. A rectangle is __________________ a rhombus.
Lesechka [4]
Hi!

A rectangle can sometimes be a rhombus if it has sides of all equal lengths. If a rectangle was a rhombus, it would also be a square. Furthermore, a square is always a rhombus.

Hope this helps! :)

What is the y-intercept Of the function Represented by the table of values belowX -2 1 2 4 7 y 15 6 3 -3 -12
Kipish [7]

Given:

The table of values.

To find:

The y-intercept of the given function.

Solution:

The table of values represents a linear function because the rate of change is constant.

Consider any two points from the given table. Let the two points are (-2,15) and (1,6). Then the equation of the linear function is

y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)

y-15=\dfrac{6-15}{1-(-2)}(x-(-2))

y-15=\dfrac{-9}{1+2}(x+2)

y-15=\dfrac{-9}{3}(x+2)

y-15=-3(x+2)

Adding 15 on both sides, we get

y=-3x-6+15

y=-3x+9

Putting x=0, we get

y=-3(0)+9

y=0+9

y=9

The y-intercept is 9. Therefore, the correct option is C.

Using a stopwatch, Tyrone determines it takes him 58. 2 minutes to travel 30 miles to work. The stopwatch measures to hundredths
nekit [7.7K]

The most accurate determination for the number of 45.36 feet per second Tyrone traveled on his way to work.

Given that,

Using a stopwatch Tyrone determines it takes him 58.2 minutes to travel 30 miles to work the stopwatch measures to hundredths of a minute going by the accuracy of the stopwatch.

We have to determine,

Which is the most accurate determination for the number of feet per second Tyrone traveled on his way to work?

According to the question,

Tyrone determines it takes him 58.2 minutes to travel 30 miles to work,

the stopwatch measures to hundredths of a minute going by the accuracy of the stopwatch are determined by,

\rm  Speed = \dfrac{Distance}{Time}

Substitute the values in the equation,

\rm  Speed = \dfrac{Distance}{Time}\\\\Speed = \dfrac{30}{58.2}\\\\Speed = \dfrac{50}{97}  \ miles \ per \ minute

If 1 mile = 5,280 feet, then his speed is,

\rm  Speed = \dfrac{50}{97}  \ miles \ per \ minute\\\\  Speed = \dfrac{50}{97}  \times 5280 \\\\ Speed= \dfrac{26,400}{97}\ feet \ per \ minute\\

And 1 minute = 60 seconds, then his speed is,

\rm  Speed= \dfrac{26,400}{97}\ feet \ per \ minute\\\\ Speed= \dfrac{26,400}{97} \times \dfrac{1}{60} \\\\ Speed = \dfrac{4400}{97} \ feet \ per \ second \\\\ Speed = 45.36 \ feet \ per \ second

Hence, The most accurate determination for the number of 45.36 feet per second Tyrone traveled on his way to work.
