The product a number with its square is equal to 8. Find the number.

Answer:

the number is 2

Step-by-step explanation:

Let us assume the number to x.

So, according to the equation:

$\textrm{x}\times\textrm{x}^{2}=8\\ \textrm{x}^{3}=8\\ \textrm{x}=\sqrt[3]{8}\\ \therefore \textrm{x}=2$

Given parallelogram ABCD, diagonals AC and BD intersect at point E. AE=2x, BE=y+10, CE=x+2 and DE=4y−8. Find y.

Answer:

B. 6

Step-by-step explanation:

The diagonals of a parallelogram intersect at their midpoints, so ...

DE = BE

4y -8 = y +10

3y = 18 . . . . . . . add 8-y

y = 6 . . . . . . . . divide by 3

Additional comment

The value of x is found the same way:

2x = x+2 ⇒ x = 2

The table lists the number of male and female students at Lakeside High school.

AysviL [449]

Answer:

C) 161/163

Step-by-step explanation:

First, you add up all the students for both genders.

Female- 193+ 214 +197+ 201 = 805

Male- 216+ 207+ 198 + 194 = 815

That gives you a fraction on 805/815 which you simplify to 161/163

So your answer would be C, 161/163 :)
