What number falls between √60 and √75
Natalija [7]
To find the number halfway between 60 and 75, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 60 and 75 into our formula, we get:

(60 + 75)/2 = 67.5

Thus, the number halfway between 60 and 75 is 67.5.

F(x) = x2 + 4x − 6
german

Since

x^2+4x+4=(x+2)^2

Is a perfect square, we can think of the "-6" at the end as a "+4-10" and we have

x^2+4x-6 = x^2+4x+4-10 = (x+2)^2-10

How many 16-ounce bottles would be needed to hold the same total amount of water 56 bottles that each holds 20 ounces
snow_lady [41]

70 bottles will hold 16 ounces amount same as 56 bottles hold 20 ounces.

Step-by-step explanation:

Given,

56 bottles hold 20 ounces each.

Total amount 56 bottles hold= 56x20

Total amount hold by 56 bottles= 1120 ounces

Let the number of 16 ounces bottles be = x

Total amount hold by x bottles = 16x

According to the given statement both amounts are same;  

16x=1120\\Dividing\ both\ sides\ by\ 16\\\frac{16x}{16} = \frac{1120}{16} \\x=70

70 bottles will hold 16 ounces amount same as 56 bottles hold 20 ounces.

Find the values of x and y that makes each equation true. –(5y)i+12=4x+25i
vovikov84 [41]

Equate real part and imaginary part:

LHS:

real part -- 12

imaginary part -- 5y

RHS:

real part = 4x

imaginary part = 25

Equating::

12 = 4x

x = 12/4

x = 3

Again:

5y = 25

y = 25/5

y = 5

So,

x = 3

y = 5
