Joyce baked a cake using 2 3/4 cups of brown sugar and 1 3/4 cups of powdered sugar. How many cups of sugar did she use in her cake? (Answers above in photo)

Answers

Answer 1

Answer: So she has used two kinds of sugar, brown and powdered.

She used $2 (3)/(4)$ cups of brown sugar and $1 (3)/(4)$ cups of powdered sugar: we need to add the two numbers:

$2 (3)/(4)$ + $1 (3)/(4)$ = 2+1+ $(3)/(4)+ (3)/(4)$ =3 $(6)/(4)=3+1+ (2)/(4) =4 (2)/(4)=4 (1)/(2)=4.5$

so the correct answer is 4.5

A large container holds 5 gallons of water. it begins leaking at a constant rate. After 10 minutes the container has 3 gallons of water left. at what rate is the water leaking?

Answers

The required rate of water leaking is 0.2 gallons of water per minute.

Given that,

A large container holds 5 gallons of water. it begins leaking at a constant rate. After 10 minutes the container has 3 gallons of water left. at what rate is the water leaking is to be determined.

What is the rate of change?

The rate of change is defined as the change in value with the rest of the time is called rate of change.

Here,
Total volume = 5 gallons
Volume left after 10 min = 3 gallons
Rate = [total volume - volume left] / 10
rate = 5 - 3 / 10
Rate = 2 / 10
Rate = 0.2

Thus, the required rate of water leaking is 0.2 gallons of water per minute.

First we have to find how much water leaked
5galllons-3 gallons=2 galllos of water leaked
Now we know $(2 galllons)/(10 minutes)$
Finally we can simplify it $(2 gallons)/(10 minutes)= (1 gallon)/(5 minutes)$ - its the answer
