Answer:

Mass of the liquid in the tank will be 1.45\times 10^8kg

Step-by-step explanation:

We have given volume of tar V=3.20\times 10^5gallon

1 gallon = 3.785 liter

So 3.20\times 10^5gallon=3.20\times 10^{5}\times 3.785=12.112\times 10^5liter

Specific gravity = 1.2

Density of water =1000kg/m^3

We know that specific gravity =\frac{density\ of\ liquid}{density\ of\ water}

1.2=\frac{density\ of\ liquid}{density\ of\ water}

Density of liquid =1200kg/m^3

So mass of liquid = volume × density

= 12.112\times 10^5\times 1200=1.45\times 10^8kg

So mass of the liquid in the tank will be 1.45\times 10^8kg

How many degrees is the measurement of angle 1? show you work GVING BRAINLY
Andru [333]

Answer:

m<1 = 79°

Step-by-step explanation:

12x + 19 + 22x - 9 = 180

add the numbers

34x + 10 =180

minus 10

34x = 170

divide by 34

x = 5

plug 5 into the equation of angle 1

12(5) + 19 =

79

The sum of two numbers is 98 and the difference between them is 48. find the two numbers.
zavuch27 [327]
So first what you want to do is take 98 and subtract it by 48. Which gives us 50. Now what we do is that since we are finding two numbers we would have to divide that by half, which would give us 25. Both of them are now equal. To find the number that makes that difference, we need to add 48 to one of the 25 values. Which would be 73. Meaning that the two numbers are 73 and 25. They both add up to 98 and 73 has a difference of 48 from 25.

(9 x 10) + (20x + 21) = 571<br><br> What does (x) equal
creativ13 [48]
(9 × 10) + (20x + 21) = 571
90 + 20x + 21 = 571
111 + 20x = 571
- 111
20x = 460
÷ 20
x = 23

What's -1.55 as a fraction? show work please help
expeople1 [14]

Answer:

hope it's help you dear

Step-by-step explanation:

The decimal part of your number seems to have the repeating digit 5 in it.

Your original number to convert is 1.550000. Let's slide the decimal point in this number to the right 1 place(s) (the same number of digits in the number 5).

If we do this, we'll get a 15.500000 (slide the decimal in the 1.550000 right 1 places, you'll get 15.500000).

So what? Well now, we have two numbers with the same repeating decimal parts, 15.500000 and 1.550000.

Now let's just work a little algebra into all of this. Let's call your original number x. And in this case, x=1.550000. The number with the decimal point slid over can be called 10x, because 10x=15.500000

What if we subtracted these two equations (that is, subtract the items on the left of the equal sign

from the stuff on the right of the equal sign)?

10x = 15.5

- x = 1.55

----------

9x = 13.95.

Now here's the important result of doing all of this: Notice how all of the repeating decimal parts have subtracted away to zero! We are left with a nice, simple 14 on the right side of the equal sign.

Now, solving 9x=14 for x by dividing both sides of it by 9, we'll get that x=14/9. And this is your answer.

How is this your answer? Well remember that above, x was originally set equal to 1.550000 via x=1.550000, and now we have that x is also equal to 14/9, so that means 1.550000=14/9..and there's 1.550000 written as a fraction!

The fraction is an improper fraction (the numerator is greater than the denominator).

While there is nothing incorrect about this, an improper fraction is typically

simplified further into a mixed number.

The whole number part of the mixed number is found by dividing the 14 by the 9.

In this case we get 1.

The fractional part of the mixed number is found by using the remainder of the division,

which in this case is 5 (14 divided by 9 is 1 remainder 5).

So your final answer is: 1.550000 can be written as the fraction
