Square root of a number is 2 numbers that multiply to get 4 that are the same
first find the factors
4=2 times 2
then find the doubles and write only one from each pair
√4=2
so if you had a number like 36 then
36=2 times 2 times 3 times 3
the doubles are 2 and 3 so
√36=2 times 3=6
square root of 4 can be 2 or -2
Answer:
2.5
Step-by-step explanation:
5/2=2.5
half of 2 is 1 so for 1 cup of coco has 2.5 tbs of coco.
Answer:
The force is 12 N
Step-by-step explanation:
* Lets explain how to solve the problem
- Direct variation is a relationship between two variables that can
be expressed by an equation in which one variable is equal to a
constant times the other
- If y ∝ x , then y = kx , where k is the constant of variation
* Lets solve the problem
- The force acting on the object varies directly with the object's
acceleration
∵ The force is F in newtons and a is the acceleration is m/s²
∴ F ∝ a
∴ F = ka
- To find k substitute F and a by the initial values of them
∵ A force of 10 N acts on a certain object, the acceleration of the
object is 5 m/s²
∵ F = 10 N when a = 5 m/s²
∵ F = ka
∴ 10 = k(5)
- Divide both sides by 5
∴ K = 2
- Substitute the value of k in the equation
∴ F = 2a
- Lets find the force when the acceleration is 6 m/s²
∵ a = 6 m/s²
∴ F = 2(6) = 12
* The force is 12 N
