A tank weighs 5.6kg when it 1/4 filled with water.If it weighs 10.4kg when it is full ,what will be it's weight when it is empty
Schach [20]

Answer:

4 kg

Step-by-step explanation:

so 1.6 * 4 is 6.4 so you just double check if you want

4 + 1.6 which is 1/4 of 6.4 will be 5.6 (matches with the question)

4 + (1.6*4) (indicates it's full) = 10.4( also Matches with the question)

there is another way by setting up an equation. let me know in comments if you want to see it that way

Fine the equation of the line that is perpendicular to the given line and passes through the given point. Enter the right side o
Kipish [7]

Answer:

y=-\frac{4}{7} x+\frac{55}{7}

Step-by-step explanation:

Change the given equation to slope-intercept to get y=\frac{7}{4}x-\frac{1}{4}. When you multiply the slopes of perpendicular lines, you get -1. -1 divided by \frac{7}{4} is -\frac{4}{7}. The slope of the new line is then -\frac{4}{7}. The perpendicular line passes through (5, 5) so you can have the equation5=-\frac{4}{7} (5)+b. Simplifying gets b = \frac{55}{7} . So now the final equation for the perpendicular line is y=-\frac{4}{7} x+\frac{55}{7}

Plzzzzzzzzzzzzzzzzzzzzzz find the hcf of 15a²b² and -24ab
Ad libitum [116K]

Let's take a look at each term separately.

15a^2b^2:

15 has factors 1, 3, 5, 15

a x a

b x b

-24ab

-24 has factors 1, 2, 3, 4, 6, 8, 12, 24

a

b

Now, we can see what each of these terms has in common. Both have a 3 in their factor lists, as well as one a and one b.

Therefore, the greatest common factor is 3ab.

Hope this helps!! :)
