With a full ink cartridge, the printer can print 2,500 pages. The printer cartridge is now 37% full. Which is the best estimate
stira [4]

Answer: 925 pages

Step-by-step explanation:

From the question, we are told that with a full ink cartridge, a printer can print 2,500 pages but that the printer cartridge is now 37% full.

The best estimate of the number of pages the printer can still print will be calculated as:

= 37% × 2500

= 0.37 × 2500

= 925 pages

A scientist has saline solutions with concentrations of 4% and 14% . He wants to mix some of each solution to get 65 milliliters
Komok [63]
Let volume of 4% solution = x and of 14% be y

them x + y = 65........(1)    also  using the actual weights of  salt:-

0.04x + 0.14y  =  65*0.06 = 3.9

multiplying the above equation by  -25 we have

-x - 3.5y = -97.5    adding this to equation (1)

--2.5y = -32.5
y= 13 

and x = 65 - 13 = 52

so we need 13 mls of the 14%,  and 52 mls of the 4% solution.

Solve for the roots in simplest form using the quadratic formula:<br> 4x2 + 4x = -5
weqwewe [10]

Answer:

Step-by-step explanation:

Move all terms to one side

4x^2 + 4x + 5 = 0

Plug into quadratic formula

x = (-4 <u>+</u> \sqrt{16 - 4(4)(5)}) / 2(4)

  = (-4 <u>+</u> \sqrt{-64})/8

At this point, there are no real answers. The roots to this equation are complex.

x = (-4 <u>+</u> 8i)/8

  = (-1 <u>+</u> 2i)/2
