32 ounces of water in a glass someone drink 55% how many ounces left in glass

borishaifa [10]

Hello!

Convert 55% to a decimal by dividing it by 100.

55 ÷ 100 = 0.55

Next, multiply the total amount of ounces of water by this decimal.

32 × 0.55 = 17.6

Finally, subtract the amount of ounces that person drank from the total number of ounces before they drank.

32 - 17.6 = 14.4

ANSWER:

14.4 ounces of water are left in the glass.

Ipatiy [6.2K]

Answer:

There are 16 Oak tree in the forest.

Step-by-step explanation:

Given: There are 4 Oak tree on every 10 pine trees.

There are total 24 more pine tree than Oak tree.

Using the ratio of trees to find the number of trees.

Lets assume there are total number of Oak tree be "x".

∴ Total number of Pine trees will be $"x+24"$

We know the ratio of Oak to Pine tree is 4:10 or $\frac{4}{10}$

⇒ $\frac{x}{x+24} = \frac{4}{10}$

Multiplying both side by $x+24$

⇒ $x= \frac{4(x+24)}{10}$

Using distributive property of multiplication, distributing 4 with x and 24.

⇒ $x= \frac{4x+96}{10}$

Multiplying both side by 10

⇒ $10x= 4x+96$

subtracting both side by 4x

⇒ $6x= 96$

dividing both side by 6

⇒ $x= \frac{96}{6}$

∴ $x= 16$

Hence, There are 16 Oak trees in the forest.
