Answer:

y^3 =30

y= (30)^(1/3) ------(1)

z=10 -------(2) -----(2)

From (1) and (2);

(y * z)^12 = (y)^12  * (z)^12

           =  ((30)^(1/3))^12  * (10)^12

           = (30)^(12/3)*  (10)^12

           =  (30)^(4) * (10)^12

           = 810 000  * (10)^12

           = 81 * (10)^16

In a survey of 300 house wires. It was discovered
ruslelena [56]

Answer:

46 housewives read all three magazines.

Step-by-step explanation:

Given:

        n(A) = 150

        n(B) = 200

        n(C) = 156

        n(A∩B) = 48

        n(B∩C) = 60

        n(A∩C) = 52

         n(A∪B∪C) = 300

so we know the relation as:

  n(A∪B∪C) = n(A) + n(B) + n(C) - n(A∩B) - n(B∩C) - n(A∩C) + n(A∩B∩C)

∴ n(A∩B∩C) = n(A) + n(B) + n(C) - n(A∩B) - n(B∩C) - n(A∩C)  - n(A∪B∪C)

                    = 150 + 200+ 156 - 48 - 60 - 52 - 300

                   = 46

Hence the number of housewives that had read all three magazine is 46.

In the figure, ∠1 ≅ ∠2, ∠3 ≅ ∠4, and . You can justify the conclusion that ∠TKL ≅ ∠TLK by stating _____
VladimirAG [237]
From the question, we know that we will be looking at <3, <4, and angles TKL and TLK. That being said, since <3 is congruent to <4, that means that angles TKL and TLK, which are each supplementary to either angle 3 or 4, are congruent because, since angles 3 and 4 are congruent, they are congruent because the supplements of congruent angles are congruent.

Slope: -2/3 y-intercept: -8 find the linear equation
puteri [66]

Answer:

y = - \frac{2}{3} x - 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - \frac{2}{3} and c = - 8, hence

y = - \frac{2}{3} x - 8 ← linear equation
