A rectangle doormat is 21 inches long and has an area of 714 squar inches. Find its width. Will the doormat fit in an

Answer:

(x - 3)² = -9

Solution:

Subtract seven from both sides. After you do that, simplify, then divide both sides by -4.

Also, quadractic bit of it is x = 3i + 3, x = -3i + 3.

Answer:

x=3+3i, 3-3i

Step-by-step explanation:

-4(x-3)²+7=43

(x-3)(x-3)= x²-6x+9

-4(x²-6x+9)+7=43

-4x²+24x-36+7=43

-4x²+24x-29=43

-4x²+24x-72=0

-x²+6x-18=0

Quadratic formula: -b+√(b²-4ac)  / 2a

-(-6)+√((-6)²-4(1)(18))   /  2(1)

6+√(36-72)   /2

6+√(-36)   / 2

x=6+6i   / 2

x=3+3i, 3-3i

Step-by-step explanation:

The Titanic could stay afloat with four of its 16 watertight compartments flooded, more than anyone could imagine on a ship of its size. ... As the ice bumped along its starboard side, it punched holes in the ship's steel plates, flooding six compartments. In a little over two hours, the Titanic filled with water and sank.

Answer:

630 is the LCM

Step-by-step explanation:

Prime factorization of the numbers:

30 = 2 × 3 × 5

90 = 2 × 3 × 3 × 5

315 = 3 × 3 × 5 × 7

LCM(30, 90, 315)

= 2 × 3 × 3 × 5 × 7

= 630

hope this helps :)

Answer:

36

Step-by-step explanation:

We are dealing with imaginary numbers, which works differently than a normal problem.

Let's combine (9i) and (i^2) and create a multiplication problem,

9ii^2 * 4i

Multiply the constants :

[tex]36i^2ii[/tex]

We see 4 i's in this problem, add them all together :

[tex]36i^4[/tex]

4 i's are equal to 1, now multiply the constant :

[tex]36 * 1[/tex]

36

Step-by-step explanation:

Answer:

2700

Step-by-step explanation:

Given data

Time= 3 years

Principal= 30000

Rate= 3%

The simple interest formula is given as

SI=PR/100

substitute

SI= 30000*3*3/100

SI= 270000/100

SI= 2700

Hence the Interest is 2700

Explanation:

See the diagram below. It shows there are 10 sides, so n = 10.

We'll plug this value of n into the formula below to find the sum of all ten interior angles

S = sum of interior angles

S = 180(n-2)

S = 180(10-2)

S = 180(8)

S = 1440 degrees

---------------

A different approach:

Let's assume this polygon is a regular polygon. This means each angle is congruent to one another.

We have n = 10 sides, so each exterior angle is E = 360/n = 360/10 = 36 degrees.

Each interior angle adjacent to this 36 degree exterior angle is

180-E = 180-36 = 144 degrees

Since we have 10 equal angles of 144 degrees each, so overall the interior angles add to 10*144 = 1440 degrees

Side note: if this polygon is not a regular polygon, then this section does not apply. You would use the first method instead.

Answer:

Scale factor = [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

Formula for the scale factor is,

Scale factor = [tex]\frac{\text{Dimension of the model}}{\text{Dimension of the original}}[/tex]

                    = [tex]\frac{\text{Dimension of the model}}{\text{Dimension of the bridge}}[/tex]

                    = [tex]\frac{\text{Width of the model}}{\text{Width of the bridge}}[/tex]

                    = [tex]\frac{7}{35}[/tex]

                    = [tex]\frac{1}{5}[/tex]

Therefore, scale factor of the model to the real bridge = [tex]\frac{1}{5}[/tex]

Answer:

Step-by-step explanation:

B = 22 × 3 × 52?—or is it supposed to be

B = 2² × 3 × 5² ?

A = 2² × 3 × 5

B = 2² × 3 × 5²

GCF = 2² × 3 × 5 = 60

A = 2² × 3 × 5

B = 22 × 3 × 52 = 2³ × 3 × 5 × 11 × 13

GCF = 2² × 3 × 5 = 60

Answer:

[tex]BAC = 276[/tex]

Step-by-step explanation:

Given

See attachment

Required

Find BAC

The sum of [tex]angles\ at\ a\ point[/tex] is 360.

So:

[tex]7n + 12 + 13n - 16 + 6n = 360[/tex]

Collect like terms

[tex]7n + 13n + 6n = 360 + 16 - 12[/tex]

[tex]26n = 364[/tex]

Solve for n

[tex]n = 364/26[/tex]

[tex]n = 14[/tex]

From the circle:

[tex]BAC = 7n + 12 + 13n - 16[/tex]

Substitute 14 for n

[tex]BAC = 7*14 + 12 + 13*14 - 16[/tex]

[tex]BAC = 276[/tex]

Answer:

d)

Step-by-step explanation:

As it always n X n, from first row, there is 1 or 1 X 1, the second row is 4 which is 2 X 2, then keep going, so for nth row, there will be n X n cube.
