Answer:

x = 64 m

Step-by-step explanation:

The scale is proportional to the actual:

(6 m)/(3/4 cm) = x/(8 cm)

Multiplying by 8 cm, we get ...

x = (8 cm)·(6 m)/(3/4 cm)

x = 64 m . . . . the width of the actual wall

Answer:

The wall is ninety meters wide.

Step-by-step explanation:

Set up and solve a proportion to find the value of w

Cancel out the like units on both sides of the equation.

Equate the cross-products, and then solve for w.

The actual width of the wall is ninety meters.

Joseph needs 6 1/2 cups of cooked rice for a recipe of nasi gorang. If 2 cups of uncooked rice with 2 1/2 cups of water make 4 1

liraira [26]

Answer:

The number of the cups of uncooked rice is 3 cups

The number of the cups of water is $3\frac{3}{4}$ cups

Step-by-step explanation:

* Let us read the recipe of Nasi Gorang

- 2 cups of uncooked rice need $2\frac{1}{2}$ cups of water to

make $4\frac{1}{3}$ cups of cooked rice

- Joseph needs $6\frac{1}{2}$ cups of cooked rice

- We need to know how many cups of uncooked rice Joshep needs

for this recipe and how much water should be added

* We can solve this problem by using the ratio method

⇒ uncooked cups : water cups : cooked cups

⇒ 2 : $2\frac{1}{2}$ : $4\frac{1}{3}$

⇒ x : y : $6\frac{1}{2}$

- By using cross multiplication

∵ x ( $4\frac{1}{3}$ ) = 2 ( $6\frac{1}{2}$ )

∵ $4\frac{1}{3}$ = $\frac{13}{3}$

∵ $6\frac{1}{2}$ = $\frac{13}{2}$

∴ x ( $\frac{13}{3}$ ) = 2 ( $\frac{13}{2}$ )

∴ $\frac{13}{3}$ x = 13

- Divide both sides by $\frac{13}{3}$

∴ x = 3

∴ The number of the cups of uncooked rice is 3 cups

- By using cross multiplication

∵ y ( $4\frac{1}{3}$ ) = ( $2\frac{1}{2}$ )( $6\frac{1}{2}$ )

∵ $2\frac{1}{2}$ = $\frac{5}{2}$

∵ $6\frac{1}{2}$ = $\frac{13}{2}$

∵ $4\frac{1}{3}$ = $\frac{13}{3}$

∴ $\frac{13}{3}$ y = ( $\frac{5}{2}$ )( $\frac{13}{2}$ )

∴ $\frac{13}{3}$ y = $\frac{65}{4}$

- Divide both sides by $\frac{13}{3}$

∴ y = $3\frac{3}{4}$

∴ The number of the cups of water is $3\frac{3}{4}$ cups

Write (2 – i)4 in simplest a + bi form.

mr_godi [17]

Answer:

Answer : 21 - 20i

Step-by-step explanation:

${(2 - i)}^{4} = (2 - i) {}^{2} (2 - i) {}^{2} \\ \\ = (4 - 2i - {i}^{2} )(4 - 2i - {i}^{2} )$

remember i² is -1 :

$= (4 - 2i - ( - 1))(4 - 2i - ( - 1)) \\ = (5 - 2i)(5 - 2i) \\ \\ = (25 - 20i + 4 {i}^{2} ) \\ = (25 - 20i + 4( - 1)) \\ = (25 - 20i - 4) \\ = 21 - 20i$
