Answer:</h2>
The score range for the smallest percent of students is:
400 to 700
<h2>
Step-by-step explanation:</h2>
From the pie chart or circle graph that is provided to us the smallest percent of the students are 10%
( Since 10% is smallest among 14%,42%,34% and 10%)
and we may observe that the smallest region is denoted or represented by the dark blue region and the range of the score of blue region that is given to us is:
400 to 700
Hence, the answer is:
400 to 700
whenever you see this kind of question you don't need to start doing all the expressions, but look at the first and last numbers of the answer, the ones that cannot be changed (have no x or y or have those that cannot be changed in this expression):
the answer can't be a or c because in the given expression we can find 3x²y² and that's the only number where we can find x²y², so it cannot be changed. (you'll have 3x²y² in the answer)
now let's look at the last digit, that doesn't have a x or a y:
in b and d we can find 2 different results so this can determine which answer is correct:
let's look back at the given expression: -7+4= -3
so the answer is b

Did you learn how to factor the difference of two squares ?
This thing is the difference of two squares.
The first term is the square of 5x .
The second term is the square of 4 .
When it's factored, it's
(sum of the square roots) x (difference of the square roots) .
25 x² - 16 = (5x + 4) times (5x - 4) .
To check it, go ahead and FOIL that out, and you'll get 25x²-16 .
Answer:
4.9kg of water
Step-by-step explanation:
Dry basis is the percentage ratio of moisture amount to amount of dry product which is 175%
Ratio of moisture amount to dry product = 175 : 100
Mass of food product = 10kg
Amount of moisture in food product = 175/175+100 × 10kg = 175/275 × 10kg = 6.4kg
Wet basis is the percentage ratio of the moisture amount to the total weight of material which is 15%
Ratio of moisture amount to total weight of material is 15 : 100
Amount of moisture in food product = 15/100 × 10kg = 1.5kg
Amount of water contained in the final product = 1.5kg
Amount of other components in the food product = 10kg - 6.4kg = 3.6kg
Total amount = 1.5kg + 3.6kg = 5.1kg
% of water = 1.5kg/5.1kg × 100 = 29%
