Answer:
b × h (Notice how length and width in the triangle formula become base and height. These words are used interchangeably.
Step-by-step explanation:
based off of a mathematical equation and process
Sorry man nobody can help you unless you give us the model
The answer is A. -12°F. we can calculate it by subtracting the initial temperature from the final temperature, i.e. -7-5 = -12
3x - 2y + 4 = 0
-2y = -3x - 4
y = 3/2x + 2...slope here is 3/2. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal of a number, flip the number and change the sign. So the slope we will need is -2/3 (see how I flipped 3/2, making it -2/3...and changed the sign, making it -2/3.)
y = mx + b
slope(m) = -2/3
(4,3)...x = 4 and y = 3
now sub and find b, the y int
3 = -2/3(4) + b
3 = -8/3 + b
3 + 8/3 = b
9/3 + 8/3 = b
17/3 = b
so ur perpendicular equation is : y = -2/3x + 17/3....or 2x + 3y = 17...or 2x + 3y - 17 = 0
Answer:
(a)
(b)
(c)NO
Step-by-step explanation:
GIVEN: Solution A is an 
acid solution. Solution B is a 
acid solution.
TO FIND: (a) Find the amount of Solution A (in mL) that must be added to 
of Solution B in order to produce a 
acid solution. (b) Find the amount of Solution A and Solution B (in mL) that can be combined in order to form a 
solution that is 
acid. (c) Does there exist a combination of Solution A and Solution B that is 
acid.
SOLUTION:
(a)
Let total amount of solution A added be 
Total amount of mixture 
As resulting solution is acid solution.
Amount of acid in final solution is sum of acid in both solutions
(b)
Let amount of Solution A be 
Amount of solution B 
As resulting solution is acidic solution
Amount of acid in final solution is sum of acid in both solutions
Amount of solution B 
(c)
No as concentration of final solution can not be greater than one with higher concentration.
