A company's sales increased 20% this year, to $6740. What were their sales last year?
Lesechka [4]

The sales last year of the company is 5617

<h3>How to determine the sales last year?</h3>

The given parameters are:

Company sales = 6740

Percentage increase = 20%

The sales of the company last year (x) to date is calculated as:

Company sales = (1 + Proportion) * Last year sales

Substitute the known values in the above equation

6740 = (1 + 20%) * x

Evaluate the sum

6740 = 1.2 * x

Divide both sides by 1.2

x = 5617

Hence, the sales last year is 5617

Describe how to redrawing with a new scale.
Ghella [55]
It depends on the technology you want to use.

These days, most programs that produce images have a way to set the zoom factor. Changing that changes the scale of the drawing.

When copy machines are used for reducing or enlarging, the scale factor is set to something new by selecting the appropriate enlargement or reduction.

If you're drawing a graph, you change the scale by changing the number of units a grid line represents.

Determine the solution set of (2x - 1)2 - 100 = 0.
mylen [45]
Distribute: 4x - 2 - 100 = 0

add 102 to both sides: 4x = 102

Divide both sides by 4: x = 25.5

A cylindrical tube 9.5 cm high and 0.85 cm in diameter is used to collect blood samples. How many cubic decimeters (dmଷ ) of blo
Brums [2.3K]

Answer: 0.539 cubic decimeters of blood can be hold by the cylinder.

Step-by-step explanation:

Volume of cylinder= volume of blood it can hold = \pir^2h

Given :

Height of cylinder (h) = 9.5 cm

Diameter of cylinder (d) = 0.85 cm

Thus radius of cylinder (r) = \frac{\text {Diameter of cylinder}}{2}=\frac{0.85cm}{2}=0.425cm

Putting the values we get:

Volume of cylinder= volume of blood it can hold = 3.14\times (0.425cm)^2\times 9.5cm=5.39cm^3=0.539dm^3 [tex]      (1cm=0.1dm)

Thus 0.539 cubic decimeters of blood can be hold by the cylinder.

Which equation represents the line that passes through (-6,7) and (-3,6)
astraxan [27]

Answer:

x+3y=15

Step-by-step explanation:

<h2>Formula :- the equation of line which passes through the two points (x1,y1) and (x2,y2)</h2><h2>T-y1/y1-y2=x-x1/x1-x2[/tex]</h2>

therefore, the equation of the line which passes through the two points (-6,7) and (-3,6) is

y1=7,y2=6

x1=-6 ,x2=-3

by using above formula

y-7/7-6=x+6/-6+3

y-7=x+6/-3

by cross multiply

-3y+21=x+6

x+3y=21-6

x+3y=15

hence, this is required of line that passes through (-6,7) and (-3,6).
