Answer:
1 : 30
Step-by-step explanation:
300mm:9m
We need to change the meters to mm
1 meter is 1000 mm
so 9 m is 9000 mm
300mm:9000mm
Divide both sides by 300
300mm/300 : 9000/300
1 : 30
She spent $23.25, how I got my answer.
I divided $13.50÷2=$6.75 then I added $6.75+3=$9.75 then I added $9.75+$13.50=$23.25.
I hope this helps.
Answer:
Step-by-step explanation:
The equation
2 = (1/6)x represents this situation.
2 is 1/6 of some value. In this case, the value is the total number of marbles. 2 represents 1/6 of the total number of marbles is how to read that equation in context. Solve that equation for x
2 = (1/6)x
12 = x (multiply both sides by 6 to get rid of the fraction)
Answer:
A
Step-by-step explanation:
Discriminant is given by
If it is negative then in quadratic formula the square root part becomes negative which makes the solution complex.
so there cannot be any real solution if the Discriminant is negative or less than 0 ,
The correct option for the given question is
A
The surface area of a regular tetrahedron is computed as the product of √3 and the square of the length of one side. The length given is 5 meters, by evaluating, we will have A = √3 (a²) = √3 (25) = 43.30. The answer is B.
