Solve the algebraic expression , is it equivalent?

Answer:

Length of minutes hand= 1.5 feet

Height of the center of the clock from the ground= 8 feet

Step-by-step explanation:

At 12:15, the end of the minute hand of a clock is 8 feet above the ground.

At 12:15 the minutes hand is making a radius along the diameter of the clock which means it is at the center of the clock. In other the center of the clock is 8 feet above the ground.

At 12:30, it is 6.5 feet off the ground .

This tells length of the minutes hand the clock which is the distance from the ground minus the distance off the ground

= 8-6.5= 1.5 feet

The center of the clock is 8 feet from the ground.

The length of the minute hand is 1.5ft, the distance of the center of the clock from the ground is 8ft

To solve this problem, we have to apply logical reasoning here.

To calculate the length of the minute hand, we just have to subtract or find the difference between the minute and from the ground at 12:30 to the minute hand at 12:15.

This will give us

[tex]12:15 - 12:30 = 8 - 6.5 = 1.5ft[/tex]

The distance of the center of the clock from the ground can be gotten from the distance from the ground at 12:15. This is because at 12:15, the minute hand is at the same horizontal line with the center of the clock and this makes the distance of the center of the clock from the ground is 8ft.

Answer:

1000 possible combinations

Step-by-step explanation:

For the padlock combination code, each number can be one of 10 (0-9).

This means there are 10 possibilities for the first digit, 10 for the 2nd, 10 for the 3rd, and 10 for the 4th.

If we combine all these possibilities between the different digits we get:

10 x 10 x 10 x 10 = 1000 different combinations.

Responder:

Ptolomeu = 520

Euclides = 640

Arquimedes = 830

Explicação passo a passo:

Deixar :

Quantidade que Ptolomeu tem = x

Quantidade de Euclides = x + 120

Quantidade que Arquimedes tem = x + 120 + 190

Valor total que todos eles têm = $ 1990

Portanto,

x + x + 120 + x + 120 + 190 = 1990

3x + 430 = 1990

3x = 1990 - 430

3x = 1560

x = 520

Ptolomeu = 520

Euclides = 520 + 120 = 640

Arquimedes = 640 + 190 = 830

Completing the square method rearranges the equation to have the

square of linear equation and constant on both sides of the equation.

Responses:

The given equation is; x² - 10·x - 11 = 0

Line 1: p² - 10·p - 11 = 0

Which gives;

p² - 10·p = 11

Adding 25 to both sides gives;

Line 2: p² - 10·p + 25 = 11 + 25

11 + 25 = 36

Factorizing p² - 10·p + 25 = (p - 5)·(p - 5)  = (p - 5)²

Line 3: (p - 5)² = 36

Which gives;

p - 5 = ±√36

Line 4: p - 5 = √36 = 6 or p - 5 = -√36 = -6 (Line that has a mistake)

Line 5: p = 6 + 5 = 11, or p = -6 + 5 = -1

Line 6: p = 11 or p = -1

The constant on the left and side is then subtracted from the positive

and negative value of the square root of the right hand side to give two

results.

Answer:

12 inches

Step-by-step explanation:

Given data

Height= 11 inces

Volume=  4,973.76 cubic inches.

The expression for the volume of a cylinder is

V= πr^2h

substitute

4,973.76= 3.14*r^2*11

4,973.76= 34.54r^2

r^2= 4,973.76/ 34.54

r^2= 144

Square root both sides

r=√144

Pythagorean theorem

in right angled triangles there is a relationship that governs the length of the tree sides. if we knows the length of any two sides, the third side maybe calculated by the use of the Pythagorean theorem.

this theorem states that the square on the hypotenuse of a right angled triangle is equal to the sum of the squares on the remaining two sides.

Answer:

X = all #'s

why?

6x+10+10x < 4(4x+3)

Combined liked terms

16x + 10 < 16x +12

you can see that there is X on both sides and the lowest one has a +10 and the highest has a +12 so it will always be greater by 2

Answer:

undeterminate (all real numbers are a solution)

Step-by-step explanation:

1) multiply 4 by 4x and 3

6x + 10 + 10x < 16x + 12

2) added up the terms with x

16x + 10 < 16x + 12

3) add at the two members -16x

10 < 12

4) notice the 10 is ever < 12, so the inhequality is undetermined
