Answer:
The fat percentage in the blend amounts to 8%.
Step-by-step explanation:
Let
x -----> represent the fat percentage in the mix.
We understand that
The total of milk's volume times its fat percentage, added to cream's volume times its fat ratio, must match the overall mixture's volume times its fat percentage.
Keep in mind that
15% = 15/100 = 0.15
3% = 3/100 = 0.03
therefore
Now, solve for x
Convert that into a percentage
18*2.50=45
50-45=5
Highlighters are priced at $3, which means she bought only one highlighter.
5-3=2
45+3=48

Answer:
Area of land = 0.056 hectares
Detailed explanation: Knowing that
A typical person in the country requires 2,450 kilocalories each day. This means
An individual consumes 2450 kilocalories daily
The average kcal produced per hectare (ha) from the available food in the nation is 15,737,000 kcal/ha.
Thus, in one day, for one individual, we have
15737000 = 2450/hec
Hectare = 2450/15737000
Hectare = 1.5568 × 10 -4
The total land area required to provide sufficient kilocalories for a single person for one year in this developing country will be
Calculated hectare × 365.25
Hectare = 1.5568 × 10 -4 × 365.25
Area of land = 0.056 hectares
