If we take 28 to be the 100%, what is 21 off of it?
Answer:
100 oz
Step-by-step explanation:
to find out how many ounces in a quarter pound, multiply 16 by ... 1/8 lb = 2 oz; 1/4 lb = 4 oz; 1/3 lb = 5.33 oz; 1/2 lb = 8 oz; 1 lb = 16 oz; 1.5 lb
Reorder the terms:
6 + 14x = 15x
Solving
6 + 14x = 15x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15x' to each side of the equation.
6 + 14x + -15x = 15x + -15x
Combine like terms: 14x + -15x = -1x
6 + -1x = 15x + -15x
Combine like terms: 15x + -15x = 0
6 + -1x = 0
Add '-6' to each side of the equation.
6 + -6 + -1x = 0 + -6
Combine like terms: 6 + -6 = 0
0 + -1x = 0 + -6
-1x = 0 + -6
Combine like terms: 0 + -6 = -6
-1x = -6
Divide each side by '-1'.
x = 6
Simplifying
x = 6
Answer:
Two possible lengths for the legs A and B are:
B = 1cm, A = 14.97cm
Or:
B = 9cm, A = 12cm
Step-by-step explanation:
For a triangle rectangle, Pythagorean's theorem says that the sum of the squares of the cathetus is equal to the hypotenuse squared.
Then if the two legs of the triangle are A and B, and the hypotenuse is H, we have:
A^2 + B^2 = H^2
If we know that H = 15cm, then:
A^2 + B^2 = (15cm)^2
Now, let's isolate one of the legs:
A = √( (15cm)^2 - B^2)
Now we can just input different values of B there, and then solve the value for the other leg.
Then if we have:
B = 1cm
A = √( (15cm)^2 - (1cm)^2) = 14.97
Then we could have:
B = 1cm
A = 14.97cm
Now let's try with another value of B:
if B = 9cm, then:
A = √( (15cm)^2 - (9cm)^2) = 12 cm
Then we could have:
B = 9cm
A = 12cm
So we just found two possible lengths for the two legs of the triangle.
