Answer:
18 dish soaps
Step-by-step explanation:
I don't know what the "six-step method" is, but I do know how to solve the problem:
Let x = number of gallons of 50% solution
amount of antifreeze in 50% solution = 0.50x
amount of antifreeze in 10% solution = 0.10(80) = 8
amount of 40% solution = 0.40(x+80) = 0.40x + 32
Then, 0.50x + 8 = 0.40x + 32
0.10x = 24
x = 240 gal
Step-by-step explanation:
let (5,-5) =(x1,y1)
from eqn y=3/2x+3
slope (m)=3/2
now,
eqn in slope intercept form is;
(y-y1)=m (x-x1)
- (y-5)=3/2 (x+5)
- 2 (y-5)=3 (x+5)
- 2y-10=3x+15
- 3x-2y+25=0 is required eqn
Answer:
210 yd²
Step-by-step explanation:
If we rotate the shape we get a right angle triangle with a hypotenuse of 29 yd :
The area of a right angle triangle is given by the formula :
A = 
Substituting the 2 values given in diagram gives us :
A = 
= 420÷2 = 210
Our units will be yd² as we are dealing with area
