If i = the square root -1, what is i^3 equal to?​

Answer:

131.25 gram is gold

Step-by-step explanation:

Rock = 525 gram

Gold = 25.0% of the rock

To determine how many grams of the rock are gold,

Find 25.0% of 525 gram

= 25/100 × 525

= 0.25 × 525

= 131.25 gram

Gold = 131.25 gram of the rock

Therefore,

131.25 gram of the rock is gold

Answer:

[tex]\large\boxed{23}[/tex]

Step-by-step explanation:

Six times a number is decreased by fourteen, the result is 124.

Write an equation that represents this

(6 * x) - 14 = 124

Multiply 6 by x to remove the parenthesis

6x - 14 = 124

Add 14 to both sides of the equation

6x = 138

Divide both sides of the equation by 6

x = 23

The unknown number is [tex]\large\boxed{23}[/tex]

Hope this helps :)

Answer:

138

Step-by-step explanation

6x-14=124

6x=124+14

x=138/6        138/6=23

X=23

Answer:

A

Step-by-step explanation:

So we have the equation:

[tex]-8x+4=36[/tex]

Subtract 4 from both sides:

[tex]-8x=32[/tex]

Divide both sides by -8:

[tex]x=-4[/tex]

And we're done!

The answer is A

Answer:

A. x = -4

Step-by-step explanation:

We are given the equation:

-8x+4=36

We want to solve for x. Therefore, we must isolate x on one side of the equation.

4 is being added to -8x. The inverse of addition is subtraction. Subtract 4 from both sides of the equation.

-8x+4-4=36-4

-8x=36-4

-8x=32

x is being multiplied by -8. The inverse of multiplication is division. Divide both sides of the equation by -8.

-8x/-8=32/-8

x= 32/-8

x=-4

Let’s check our solution. Plug -4 in for x and solve.

-8x+4=36

-8(-4)+4=36

32+4=36

36=36

This checks out, so we know our solution is correct.

The solution to the equation is A. x=-4

Answer:

-8

Step-by-step explanation:

multiply -4 and -2= 8

then 8x-1= -8

when multiplying a positive by a negative it will always be a negative

Answer:

[tex]x=41/2=20.5[/tex]

Step-by-step explanation:

So we have the equation:

[tex]2x-2y=23[/tex]

And we want to find x when y is 9.

So, substitute y for 9 and solve for x:

[tex]2x-2(9)=23[/tex]

Multiply:

[tex]2x-18=23[/tex]

Add 18 to both sides:

[tex]2x=41[/tex]

Divide both sides by 2:

[tex]x=41/2=20.5[/tex]

So, our answer is 20.5

Answer:

20.5

Step-by-step explanation:

2x - 2y = 23

2x - 2(9) = 23

2x -  18 = 23

2x = 23 + 18

2x = 41

x = 20.5

Answer:

i > 4

Step-by-step explanation:

6i - 54 > 6 (3 - 2i)

6i - 54 > 18 - 12i

6i + 12i > 18 + 54

18i > 72

i > 4

Answer:

Given :

Full-time employee who works 40 hours per week earns $20.50 per hour.

To Find :

The weekly income and annual income after round off .

Solution :

Weekly income is given by :

[tex]C =40\times 20.50\\\\C=\$ 820[/tex]

Now , round off of hourly in come to nearest dollar is $21 .

So , new weekly income is :

[tex]C'=40\times 21\\\\C'=\$ 840[/tex]

Now , annual income is :

[tex]A=C'\times 50\\\\A=\$840\times 50\\\\A=\$42000[/tex]

Therefore , weekly income and estimated of annual income is $42000 .

Hence , this is the required solution .

Answer:

Perimeter, P = (24d+0.8) cm

Step-by-step explanation:

Given that,

Width of rectangle, B = (4.4d−4.3) cm

Length, l = (7.6d+4.7)

Perimeter is equal to the sum of all sides. A rectangle have 4 sides. The opposite sides of a rectangle are equal. So,

Perimeter = 2(L+B)

P = 2[(7.6d+4.7)+(4.4d−4.3)]

Collecting like terms

P = 2[(7.6d+4.4d)+(4.7−4.3)]

P=2(12d+0.4)

⇒ P = 24d+0.8

So, the expression for the perimeter of the rectangle is (24d+0.8) cm.

Answer:

$1,257.63

Step-by-step explanation:

A= p(1+r/n)^nt

P = principal = $847

r= interest rate = 2.2%

n= 360 per year

t= 18 years

A= p(1+r/n)^nt

= 847(1+0.022/360)^360*18

= 847(1+0.000061)^6,480

= 847(1.000061)^6,480

=847(1.4848)

= $1,257.63

Total balance in 18 years = $1,257.63

Answer:

ok so basically the points need to be graphed on a map and to do that you need to know the x and the y axis.x axis is horizontal and y is verticle.So look at -3,-5 the x is -3 and the y is -5 so you go left -3 and then down -5

Answer:

x = 6

One-fourth x + one-half = one-third x

Step-by-step explanation:

1/4 x + 1/2 = 1/3 x

1/4 x - 1/3 x = - 1/2

(3x - 4x)/12 = -1/2

-x/12 = -1/2

-x = -12/2

-x = -6

x = 6

Answer:

It is divisible by 1,2,3,4,5,6 and 7.

Answer:

The similarities are

1) Both diagrams consists of an horizontal line l for the upper diagram and k for the lower diagram

2) Both diagrams have a vertical plane Z for the upper diagram and A for the lower diagram

3) Both diagrams have rays, which are C for the upper diagram and G and H for the lower diagram

The differences are

1) The upper diagram has only one plane, while the lower diagram has two planes, seemingly rotated at an angle of about 90° to each other

2) The upper diagram has only one line, l, while the lower diagram has two lines, l and GH
