Answer:

18 cm

Step-by-step explanation:

The main diagonal of any cube can be found by multiplying the length of one side by the square root of 3.

Given: side x = 3 cm

Use the diagonal formula,

Diagonal of cube = 3–√x

Diagonal of cube = 3–√ × 3

We know that the value of √3 is 1.734

Therefore, the diagonal of a cube  = 1.734 (3)

Diagonal of cube = 5.20 cm

In a certain university admissions department, 70 more males than females submitted applications for admissions. 20% of the fema
Anuta_ua [19.1K]

Answer:

In total, 1130 people applied in the University.

Step-by-step explanation:

Total applicants admitted = 256

Let the number of females  who applied in University =   k

So, the number of males who applied =  ( k + 70)

Now, 20 %of females are admitted ⇒ 20% of (k) is admitted

or, the number of females admitted in university =  \frac{20}{100}  \times k = 0.2k

Also , 25 %of males are admitted ⇒  25% of (k + 70) is admitted

or, the number of males admitted in university =  \frac{25}{100}  \times (k+70) = 0.25(k+70)

So, according to the question:

0.20k + 0.25(k+70) = Total admissions = 256

or, 0.2k + 0.25k + 17.5  = 256

⇒0.45k = 238.5

or, k = 238.5/0.45 = 530

Hence, total number of females who applied = 530

And Total males who applies = ( k + 70) = 600

Now,  TOTAL Applications = MALE applications + FEMALE applications

                                              = 530 + 600 = 1130

Hence, in total 1130 people applied in the University.

Which value of x makes the following equation true?
Orlov [11]
The easiest way is to just solve the equation.
4x - 4 = -4x + 60
4x + 4x = 4 + 60
8x = 64
x = 8

A slower way to do this is to plug each of the numbers into the equation to see which makes the equation is true.
So for A.
4(8 - 1) = -4(8) + 60
4(7) = -32 + 60
28 = 28
Fortunately, this is true, so A is the answer and you don't have to try the other options.
