What is the least common denominator of the fractions 4/15 1/6 and 3/4
Alexus [3.1K]

Answer:

60

Step-by-step explanation:

We have to find least common denominator for these fractions or we just have to find the least common multiple for 15, 6 and 4

In order to find the least common multiple, we have to represent these numbers as factors of prime numbers:

15 = 3 * 5

6 = 2 * 3

4 = 2 * 2

Least common multiples will be common factors (considering that there are no more than of them in other numbers) and the uncommon factors. Then, we can write that:

2 * 2 * 3 * 5 = 60 (there are two 2's, one common 3 and an uncommon 5)

The denominator will be 60 for the least common multiples.

-2x^2+5x-4=0 , find the discriminant
BaLLatris [955]

Answer:

The discriminant is -7

Step-by-step explanation:

The discriminant of a quadratic function/equation(ax^2+bx+c = 0) is calculated as:

b^2 -4ac

Here

b is the co-efficient of x

a is the co-efficient of x^2

and c is the constant

Given equation is:

-2x^2+5x-4=0

Here

a = -2

b = 5

c = -4

Putting the values in the formula for discriminant

= b^2 - 4ac\\= (5)^2 - 4(-2)(-4)\\= 25 - 32\\=-7

As the discriminant is negative, the equation has no real solution.

Hence,

The discriminant is -7

The diagram below shows the different lengths and widths of a rectangle based on a given ratio.
Vinil7 [7]
Looking at this, the unit of 1 length is equal to 2.5 units of width. To find 6 units of length, you just multiply 6 by 2.5. Getting this gives us 15. So your answer is C.

Find the 10th term in the following arithmetic sequence if the constant being added is
Murljashka [212]

Find the 10th term in the following arithmetic sequence if the constant being added is  -12

Step-by-step explanation:

20 - 12 = 8

8 - 12 = -4

-4 - 12 = -16

So the sequence will be

20; 8; -4; -16

an = 20 - 12(n - 1)

a10 = 20 - 12(10 - 1) = -88

m_a_m_a [10]

Answer:

  • 1. ∠C = 90°
  • 2. ∠B = 90°
  • 3. ∠BAD = 90°
  • 4. ∠ADC = 90°
  • 5. ∠EDC = 90° - 53° = 37°
  • 6. ∠EDF = ∠DEC = 53°
  • 7. ∠FED = 90° - 53° = 37°
  • 8. ∠FEA = 90° - ∠FED = 90° - 37° = 53°
  • 9. ∠EFA = 90°
  • 10. ∠FAE = 90° - ∠FEA = 90° - 53° = 37°
  • 11. ∠EAB = 90° - ∠FAE = 90° - 37° = 53°
  • 12. ∠AEB = 90° - ∠EAB = 90° - 53 = 37°
