Answer:

two solutions : x=0 ; x= 2/3

Step-by-step explanation:

hello :

3x^3−x²=x²

3x^3 -2x² = 0

x²(3x-2)=0 means : x² = 0 or 3x-2 =0

x=0 or 3x =2

two solutions : x=0 or x= 2/3

Natali5045456 [20]

Complete Question:

Katya creates handmade sets of dolls, which is sold to craft and souvenir stores. The first set of dolls has a middle diameter of 7cm and a height of 12cm.

Katya made another set of dolls. In the new set, the largest doll has a diameter of 8.75 cm and a height of 15.6 cm. Is this a dilation of the first set of dolls?

Answer:

The new set is not a dilation of the first set

Step-by-step explanation:

Given

First Set:

$Height = 12cm$

$Diameter = 7cm$

New Set:

$Height = 15.6cm$

$Diameter = 8.75cm$

Required

Determine if the new set is a dilation of the second

To do this, we pass through the following steps:

1. Divide the height of the first set by the new set

2. Divide the diameter of the first set by the new set

3. Result in (1) and (2) must be equal if the new set is a dilation of the first set

Following the steps above:

(1)

$Height\ Ratio = \frac{H_2}{H_1}$

$Height\ Ratio = \frac{15.6}{12}$

$Height\ Ratio = 1.3$

(2)

$Diameter\ Ratio = \frac{D_2}{D_1}$

$Diameter\ Ratio = \frac{8.75}{7}$

$Diameter\ Ratio = 1.25$

(3) Make comparison

The ratio in (1) does not equal the ratio in (2)

i.e.

$1.3 \neq 1.25$

Hence, the new set is not a dilation of the first set

Henry and his family are eating at a rotating restaurant at the top of a tower. The restaurant rotates clockwise 90° every 15 mi

frutty [35]

Answer:

The table of Henry's family will be at (4, -4)

Step-by-step explanation:

The problem states that the initial coordinates of Henry's family is at the coordinates (-4, 4). Each 15 minutes the restaurant will rotate 90° every 15 minutes. If we follow the Cartesian plane and the center of the restaurant being at (0, 0) we know that the table will be situated at the (4, 4) coordinates of the restaurant after the first rotation. After the 30 minute mark, the restaurant rotates one more time and moves the table of Henry's family at the (4, -4) coordinates of the restaurant as the center of the restaurant will never move.

A golden rectangle has side lengths in the ratio of about 1: 1.618 if the long side of a golden rectangle is 35 cm what is its a

lakkis [162]

Answer:

The answer to your question is 757.1 cm²

Step-by-step explanation:

Data

Ratio 1: 1.618

long side = 35 cm

Area = ?

Process

1.- Use proportions to solve this problem

1 : 1.618 :: x : 35

x = (35 x 1) / 1.618

x = 35 / 1.618

x = 21.63

2.- Calculate the area of the rectangle

Area = base x height

Area = 35 x 21.63

Area = 757.1 cm²

Suppose that Prudie earns the same each day.write an inequality to find how much she needs to earn each day

Sedbober [7]

let the amount of money earned by Prudie be p

since she earns the same amount of money each day after two days she has earned 2p

therefore the amount of money she needs to earn each day equals p $\geq$ 0
