What ks the % of 4 = 2​

Mathematics
2 answers:
Fittoniya [83]3 years ago
4 0

Answer:

50\%

Step-by-step explanation:

Let x be the percentage then...

x\%(4)=2

Start by dividing both sides by 4:

x\%=\frac{2}{4}

Simplify the fraction:

x\%=\frac{1}{2}

Then, multiply the fraction by 50/50, so we can get a number over 100 (that number would be the percentage). Note we can only multiply it by 50/50 since it is essentially multiplying the fraction by 1.

x\%=\frac{1}{2}*\frac{50}{50}\\x\%=\frac{50}{100}\\x=50\%

Solution:

<u>Note that:</u>

  • x% × 4 = 2

<u>Simplify the equation and solve.</u>

  • x% × 4 = 2
  • => x/100 × 4 = 2
  • => x/25 = 2
  • => x = 2 x 25 = 50

Hence, 50% of 4 is 2.

solve the following pair of linear equation 2x+3y=5 , 7x-5y=2 has a unique solution if yes find the solution
slava [35]

Answer:

(1, 1 )

Step-by-step explanation:

Given the 2 equations

2x + 3y = 5 → (1)

7x - 5y = 2 → (2)

Multiplying (1) by 5 and (2) by 3 and adding will eliminate the y- term

10x + 15y = 25 → (3)

21x - 15y = 6 → (4)

Add (3) and (4) term by term to eliminate y

31x = 31 ( divide both sides by 31 )

x = 1

Substitute x = 1 into either of the 2 equations and evaluate for y

Substituting into (1)

2(1) + 3y = 5

2 + 3y = 5 ( subtract 2 from both sides )

3y = 3 ( divide both sides by 3 )

y = 1

Solution is (1, 1 )

What is the volume?<br> 2 mm<br> 8 mm<br> 4 mm<br> cubic millimeters
shutvik [7]

Answer:

64 mm³

Step-by-step explanation:

I am assuming there was a photo to go with this problem

However the general formula to find volume is usually V = l×w×h

  • It does not matter which measurement is which because they all get multiplied together.
  • However assigning a name to each unit of measurement we will denoted the length (l) as 2 mm, the width (w) as 8 mm, and the height (h) as 4 mm
  • Plugging these values into the formula we get: V = (2)(8)(4) = 64 mm³
