Answer:

Step-by-step explanation:

since the magnitude of xy ≠ zw,

|x-y| = xy = |52-121|= 69, |z-w| = zw = |-21-25| = 46

69 ≠ 46

Matter is in a liquid state when its temperature is between its melting point and its boiling point. Suppose that some substance

alexgriva [62]

Answer:

96.512 °F < x < 591.242 °F

Step-by-step explanation:

We are given;

Melting point = 35.84 °C

Boiling point = 310.69 °C

Now, we are given that formula to convert °C to °F is;

°C = (5/9)°F

Thus if the temperature in Fahrenheit is x, then;

Melting point is; 35.84 °C = (5/9)x°F - "32"

x = ((9 × 35.84)/5) + 32

x = 96.512 °F

Similarly, for Boiling point;

Boiling point is;

310.69 °C = (5/9)x°F - "32"

x = ((9 × 310.69)/5) + 32

x = 591.242 °F

Now, we are told that matter is in its liquid form when it is between melting and boiling point.

Thus, range of x in inequality form is;

96.512 °F < x < 591.242 °F

Walter is mixing cement for his new patio . He knows he need to use a water-to-cement ratio of 20 to 30 . What percent of his to

kherson [118]

If his water to cement ratio is 20 to 30, this means that if he uses 20 liters of water, he'd use 30 liters of cement.

The total mixture would then be 20+30=50 liters.

and the water would be 20/50=0.4 or 40% of the total mixture.

2000 divided by 5 is 400. 400 time 3 is 1200. You could also do 2000*.6 (because .6 = 3/5)

How do I find the percentage of 18/20

borishaifa [10]

Or for this and any other problem . every percentage is out of a 100

soooo ,
20 | 100 %
10 | 50 %
5 | 25 %
1 | 5 %

SOOO

10 + 5 = 15 50 % + 25 % = 75 % , so know we know 15/20 is 75 percent

but you need 18/20 not 15/20 , so 1 equals 5 % in this problem

1+1+1 = 3 5+5+5 = 15

15 + 3 = 90 75 + 15 = 90 , 18/20 = 90%

I know its probably alot but I wanted to show you all I did , so that it could maybe help you in the future , just gotta plug in different numbers
