Answer:
5 units
Step-by-step explanation:
To solve this we can use pythagoras theory:
- a² + b² = c², where c is the diagonal
- 3² + 4² = c²
- 9 + 16 = 25
- c² = 25, so c = √25
- c = 5

Answer: Three quarters (30 ml) is made up of a 36% acid solution.
Step-by-step explanation:
Since we have given that
Total amount of solution = 40 ml
One- quarter of the solution is given by

Three-quarter of the solution is given by

According to question, we have
10 ml of solution is made up of = 20% of acid solution
30 ml of solution is made up of = say<em> 'c </em>' of acid solution
40 ml of solution is made up of = 32 % of acid solution
So, our equation becomes,

Hence, three quarters (30 ml) is made up of a 36% acid solution.

Answer:
x=-2 hope this helps! :)
Step-by-step explanation:
first you move the constant to the right
3x+1=-5
then you calculate
3x=-5-1
finally you divide both sides to get x alone
x=-2
