Answer:
1. No
2. yes
3. yes
4. yes
Step-by-step explanation:
1. 2×3=6, 7×3=21 (The product of two (or more) prime numbers cannot result in another prime number. By definition, a prime number is a number that is divisible by 1 or itself - multiplying two or more primes together will always yield a number divisible by 1, itself and the prime numbers multiplied together to achieve it.
2.When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.” So, 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.
3. 1×3=3, 3×5=15 (odd numbers are not divisible by 2)Therefore, every prime number other than 2 is an odd number
4. 2×4=8, 6×8=48
Answer:
16/3 or 5 1/3
Step-by-step explanation:
Since 12 isn't over 50, you would round to the lower hundred. The answer is 13,900.
Row 1. Here you have the sum
Meat+
Beans+
Rice, so the expression represent the
the total price of all the food.
Row 2. Here you have the sum
Beans+
Rice. Since both foods are plants, the expression represent
the total price of the foods from plants.
Row 3. Here you have the sum
Meat+
Beans+
Rice again, so the expression represent the
the total price of all the food.
Row 4. Here you have the sum
Beans+
Meat. Since beans and meat are both rich in proteins, the expression represent
the total price of the foods rich in protein.
Row 5. Here you have the sum
Meat+
Rice. Since meat is not a plant and rice is not rich in protein, the correct answer is
None of these.
Row 6. Here you have the sum
Beans+
Meat again just in a different order. Since beans and meat are both rich in proteins, the expression represent
the total price of the foods rich in protein.
