Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100

Answers

Answer 1

Answer:

There are no solutions whenever k=4,5mod9.

This holds since it is not difficult to verify that for every integer n, we have n3=0,±1mod9.

Up till this year, there were just two values for k in the range 1..100 for which it was not known if there were a solution. These values are k=33,42.

Both values are now known to have solutions. See 42 is the answer to the question “

7) 2.1x + 45.2 = 3.2 -8.4x

Answers

Answer:

x=-4

Step-by-step explanation:

brainliest please

Answer:

x=-4, Give brainliest please

Step-by-step explanation:

Step 1: Add 8.4x to both sides.

2.1x+45.2 =  -8.4x +3.2

       +8.4x    +8.4x

10.5x+45.2=3.2

Step 2: Subtract 45.2 from both sides.

10.5x + 45.2 = 3.2

         -45.2    -45.2

10.5x=−42

Step 3: Divide both sides by 10.5.

[tex]\frac{10.5x}{10\\}[/tex]=[tex]\frac{-42}{10}[/tex]

On the coldest day of the year, the temperature at noon was 11℉. By midnight, the temperature had decreased by 15.5℉. What was the temperature at midnight? *

Answers

Answer: -4.5 ℉

Step-by-step explanation:

Given: On the coldest day of the year, the temperature at noon = 11℉

By midnight, the temperature had decreased by 15.5℉.

i.e. The temperature at midnight = Temperature at noon - 15.5℉

= 11℉ - 15.5℉

= (11-15) ℉

= -4.5 ℉

Hence, the temperature at midnight was -4.5 ℉.

What unit is used to measure the density of a solid??

Answers

Answer:

Grams per cubic meter or g/cm3

Step-by-step explanation:

The answers vary, but they have the same format which is

density = mass/volume

For instance, if the mass is in grams and the volume is in cubic centimeters, then the density would be in grams/cm^3, where "cm^3" is the abbreviation of "cubic centimeters". We can read "grams/cm^3" out as "grams per cubic centimeter"

(c) is a circle of center O and radius R=2 cm, and A is a point such that OA=3 cm. There exist two circles of center A and tangent to (c). Construct these circles; calculate their radii

Answers

Given :

C) is a circle of center O and radius R=2 cm, and A is a point such that OA=3 cm.

There exist two circles of center A and tangent to (C).

To Find :

The radius of the new circles.

Solution :

Since, OA is 3 cm .

So, first circle with tangent to C if centre is at A is OA itself.

First radius, r = 3 cm.

And second circle is the on with radius , R = 3 + 2 = 5 cm.

Therefore, the radius of both the circles are 3 cm and 5 cm.

Hence, this is the required solution.

In the accompanying diagram of a parallelogram
ABCD ,DC= 5x-18, BC=3x-6, AB=2x+12 find measure BC. Please help

Answers

Answer:

BC = 39

Step-by-step explanation:

Given:

DC = 5x - 18,

BC = 3x - 6,

AB = 2x + 12

Opposite sides of a parallelogram are equal.

Therefore:

AB = DC

2x + 12 = 5x - 18

Collect like terms

12 + 18 = 5x - 3x

30 = 2x

Divide both sides by 2

15 = x

x = 15

BC = 3x - 6

Plug in the value of x

BC = 3(15) - 6 = 45 - 6

BC = 39
