PLEASE HELPP!! Round each mixed number to the nearest whole number. Then, estimate the sum.

A number, y, is equal to the difference of a larger number and 3. The same number is one third of the sum of the larger

Mnenie [13.5K]

Answer:

Set the larger number as x

"A number, y, is equal to the difference of a larger number and 3."

$y=x-3$

You can rearrange this equation to find the matching answer choice:

$y-x=-3\\x-y=3$

"The same number is one third of the sum of the larger number and 9."

$y=\frac{1}{3} (x+9)$

You can rearrange this equation to find the matching answer choice:

$y=\frac{1}{3} x+3\\3y=x+9\\3y-x=9\\x-3y=-9$

The volume of a rectangular prism can be computed using formula v = Iwh what is the height of a prism that has a volume of 2376

Blizzard [7]

Answer:

Answer is A. 12

Step-by-step explanation:

Volume of a rectangular prism = Length * Width * Height

Volume of the rectangular prism = $2376cm^{3}$

Length of the prism = 18cm

Width of the prism = 11cm

We need to find the Height of the Prism,

For that first make the Height as subject of the equation,

Height = [Volume of the rectangular prism/(Length * Width)]

= $2376cm^{3}$ /(18cm*11cm)

= $2376cm^{3}$ / $198cm^{2}$

= $12cm$

Therefore,

The weekly salaries of six employees at McDonalds are $140, $220, $90, $180, $140, $200. For these six salaries, determine: (a)

lys-0071 [83]

Answer:

a) Mean = 161.666667

b)Mode = 140

c) Median =160

d) Range =130

Step-by-step explanation:

Given that the weekly salaries of six employees =$140, $220, $90, $180, $140, $200

Mean =Total number of salaries/ Number of salaries

=$140 +$220 +$90 +$180 + $140 +$200 /6=970/6= 161.666667

Mode = The number with the highest frequency ie the number that occurs most in the listed salaries

$140, $220, $90, $180, $140, $200

Therefore 140 is the mode

Median = The number that occurs in the middle, Now that we have a list of even Numbers, our median would be the sum of the two middle numbers divided by 2 after arranging in ascending order fro least to greatest

$90, $140,$140, $180, $200,$220

Median =$140+ $180 / 2 = 160

Range = The difference between the highest and lowest number in the sample

$220-$90=130

What’s the equation for a line passing through points (-1, 4.5) and (6, 8)?

san4es73 [151]

Answer:

Given points ( -1 , 4.5 ) and ( 6 , 8 )

Step-by-step explanation:

first we should calculate slope 

Slope ( m) 

= ( y2 - y1) / ( x2 - x1) 

= ( 8 - 4.5 ) / ( 6 + 1 )

= 3.5/7

= 0.5

Now the equation of line is given by 

y - y1 = m ( x - x1 )

y - 4.5 = 0.5 ( x + 1 )

( y - 4.5 ) = 0.5 ( x + 1)

y - 4.5 = 0.5x + 0.5

y = 0.5x + 0.5 + 4.5

y = 0.5x + 5
