What is the solution to this problem: (4/9)/(2/3)/(5/6)

valentina_108 [34]

(4/9)/(2/3)/(5/6)

First, invert and multiply. / Your problem should look like: $\frac{4}{9} \\ \frac{2}{3}$ × $\frac{6}{5}$
Second, invert and multiply. / Your problem should look like: $\frac{4}{9}$ × $\frac{3}{2}$ × $\frac{6}{5}$
Third, apply this rule: $\frac{a}{b}$ × $\frac{c}{d}$ . / Your problem should look like: $\frac{4 x 3 x 6}{9 x 2 x 5}$
Fourth, simplify 4 × 3 × 6 to 72. / Your problem should look like: $\frac{72}{9x2x5}$
Fifth, simplify 9 × 2 × 5 to 90. / Your problem should look like: $\frac{72}{90}$
Sixth, simplify. / Your problem should look like: $\frac{4}{5}$

One kind of hard candy sells for $.89 per kilogram another sells for $1.10 per kilogram how many kilograms of each kind a need t

Furkat [3]

Answer:

20kg of $0.89 candy

10kg of $1.10 candy

Step-by-step explanation:

Candy 1 = 0.89 per kg

Candy 2 = 1.10 per kg

Total kilogram, kg = 30

Let candy 1 = x ; candy 2 = (30 - x) ;

0.89x + 1.10(30 - x) = 0.96(30)

0.89x + 33 - 1.10x = 28.8

0.89x - 1.10x = 28.8 - 33

-0.21x = - 4.2

x = 4.2 / 0.21

x = 20

20kg of $0.89 candy

(30 - x) = (30 - 20) = 10kg

10kg of $1.10 candy

Find x for each of these triangles please

notka56 [123]

Answer:

8) 10°

9) X can not be determined.

10) 10°

11) 12 units.

Step-by-step explanation:

8) The three sides of the given triangle are equal. Hence, the triangle is an equilateral triangle, hence each angle will be 60°.

So, 6x = 60°

⇒ x = 10°.

9) The three angles of the given triangle are equal. Hence, the triangle is an equilateral triangle, hence each side will be equal.

So, 6x - 5 = 6x

So, x can not be determined from this equation.

10) Δ KLM is equilateral, so, KN will bisect ∠ MKL. So, ∠ NKL = 30°

Hence, 3x = 30°

⇒ x = 10°

11) In Δ XYZ, XZ = XY , so, ∠ Z = ∠ Y.

Again, ∠ X is given to be 60°.

Therefore, each angle is 60°.

So, the triangle XYZ is equilateral, and each side will be equal.

So, 3x + 8 = 4x - 4

⇒ x = 12 units. (Answer)
