Answer: 140 ml
Explanation:
let x be the original amount of water
x - 15% = 119
But x = 100% because it’s the original
=> 100% - 15% = 119ml
85% = 119ml
Find the amount of water in 15%:
85% = 119
15% = y
=> 85/15 = 119/y
Cross multiply:
85y = 15 x 119
85y = 1785
y = 1785/85
y = 21
But y = 15% therefore, 15% = 21ml
Back to our equation:
x - 15% = 119ml
x - 21ml = 119ml
x = (119 + 21)ml
x = 140ml
Therefore, the original amount of water is 140ml
Hello there!
The standard form of the equation of a circle with center (h, k) and radius r is:
(x - h)² + (y - k)² = r²
So we have h = 4 and k = 3 and r = √5
So we just need to add these numbers to where they belong.
(x - 4)² + (y - 3)² = (√5)²
(x - 4)² + (y - 3)² = 5
Let me know if you have questions about the answer. As always, it is my pleasure to help students like you!

Step-by-step explanation:
Total cost of painting 225 cm² will be:
Cost=(total area)×(cost per cm²)
area=225 cm²
cost per cm²=$0.12
thus the total cost will be:
Cost=0.12×225=$27
Answer: $27
Answer:
= 9000³
Step-by-step explanation:
*Volume of the bigger box :-
20 × 20 × 20 = 8000
*Volume of the smaller box :-
10 × 10 × 10 = 1000
Therefore, volume of the aquarium :-
= 8000 + 1000 = 9000³
