Naddika [18.5K]

Answer:

16.25 mL

Step-by-step explanation:

Since we are mixing from the syrup in the inventory, we can say that the syrup in the inventory must be equal to that in the final solution. Thus, we will use the dilution equation to solve for the Initial volume;

Dilution equation is;

V₁C₁ = V₂C₂

Where;

V₁ is initial volume

C₁ is initial concentration or initial molarity

V₂ is final volume

C₂ is final concentration of final molarity

We are given;

C₁ = 80% = 0.8

C₂ = 60% = 0.6

V₂ = 65 mL

Making V₁ the subject in the dilution equation, we have;

V₁ = (V₂C₂)/C₁

V₁ = (65 × 0.6)/0.8

V₁ = 48.75 mL of inventory syrup

Since we have 48.75 mL of inventory syrup and the dilute solution is 65 ml, then the volume of soda solution required = 65mL - 48.75 mL = 16.25 mL

zahra has paper rectangles of different sizes. every rectangle is 5 cm longer than it is wide. Is there a proportional relations
Vinil7 [7]

As given Zahra has paper rectangles of different sizes.

Also, Every rectangle is 5 cm is longer than it's breadth.

So, if Length=L, then Breadth= L- 5

Or , if Breadth= B, then Length= B+5

or, if length is x and breadth is y ,then writing in terms of equation

→x=y+5

As you can see,there is not any proportional relationship between length and widths of these rectangles.

I need help to find the surface area to the nearest hundreds
Andre45 [30]

Answer:

The volume of the pentagonal prism is 1446.25

Step-by-step explanation:

First of all we need to calculate the area of the pentagon

A = area

a =  apothem = 8.9

p = perimeter = 13 * 5 = 65

A = (a*p) / 2

A = (8.9 * 65) / 2

A = 578.5 / 2

A = 289.25

To calculate the volume of a pentagonal prism we have to use the following formula:

a = area =  289.25

v = volume

h = height  = 5

v = a * h

we replace the values that ​​we know        

v =   289.25 * 5

v = 1446.25

The volume of the pentagonal prism is 1446.25

vlada-n [284]

(3,0)

Step-by-step explanation:

Different - add

2x - y = 6

+

x + y. = 3

3x = 9

÷3

x = 3

Substitute x = 3 into one of the equation:

x + y = 3

3 + y = 3

-3

y = 0

Solution is (3,0)

Hope this helps!
