so.. whatever the sum of "x" and "y" is, it must come with a 10Liter
solution of 10% or 10/100 = 0.10 acidity
thus
solve for "y" to see how much of the 25% solution must be used,
how much "x" will it be? well x = 10 -y :)
Answer:
Solution in image belo, make sure to put the lines on the right number's then out the point on (4, -3)
Answer: The answer is 25 then if it asks for the equation it is A=1/2bh
Step-by-step explanation:
The b or base is 10
The height or h is 5
A=1/2bh
A=1/2(10)(5)
A=1/2(50)
A=25
I hope this helps :)
Answer:
yes, no, yes, no
Step-by-step explanation:
For it to be a line, that means that when x goes up by 1 y goes up by the same thing every time.
7a. from (1, 12) to (2, 8), the x coordinate goes up by 1 and the y coordinate goes down by 4. From (2, 8) to (3, 4) the y coordinate again goes down by 4 when the x coordinate goes up by 1. This pattern continues for the other points, so yes.
Do the same thing for the rest and you should get:
7b. No
7c. Yes
7d. No
A Square Window would have four equal sides. So you would use the <span>Pythagorean Theorem (a</span>²+b²=c²) to solve the problem. so it would be set up like this; 40²+40²=c². then you would evaluate it and it become:
400+400=c²
800=c²
√800=√c²
