Answer:

Latoya can plant 5/6 of her garden in one hour.

Step-by-step explanation:

☆We can solve using proportion!

[tex] \frac{ \frac{1}{3 } \: of \: garden }{ \frac{2}{5} \: of \: hour } = \frac{x}{1 \: hour} \\ \\ \frac{ \: \frac { 2}{5}x }{ \frac{2}{5} } = \frac{ \frac{1}{3} }{ \frac{2}{5} } \\ \\ x = \frac{5}{6} [/tex]

Answer:

RECTANGULAR FORM: z -w = 1- 1i

POLAR FORM: z-w = √2(cos135°+i sin135°)

Step-by-step explanation:

Find the image attached

Given the following complex numbers

z = √2 (cos 45º + i sin 45° )

w = 2(cos 90° + i sin 90).

The complex number in rectangular form is expressed as z = x+iy

(x, y) are the rectangular coordinates

Given

z = √2 (cos 45º + i sin 45° )

z = √2 (1/√2+ ( 1/√2)i )

z =  √2(1/√2) +  √2(1/√2)i

z = 1 + i .... 1

Also;

w = 2(cos 90° + i sin 90)

w = 2(0 + 1i)

w  = 2(0) + 2i

w = 0+2i ....2

Take their difference:

z - w = 1 + i - (0+2i)

z-w = 1+i-0-2i

z-w = 1-0+i-2i

z-w = 1-i

Hence the values that goes into the box is 1.

z-w = 1 - 1i

In Polar form;

Get the modulus of the resulting complex number:

|z-w| = √1²+1²

|z-w| = √2

Get the argument:

[tex]\theta = tan^{-1}\frac{y}{x} \\\theta = tan^{-1}(\frac{-1}{1}) \\\theta = tan^{-1}(-1) \\\theta = -45^0[/tex]

Since tan is negative in the second quadrant, the angle will be 180-45 = 135°

The polar form of the complex umber is expressed as;

z-w = |z-w|(cosθ-isinθ)

z-w = √2(cos135°+i sin135°)

Answer:

The complement is 47° and the supplement is 137°.

Step-by-step explanation:

Complementary and Supplementary Angles

When the sum of two angles is equal to 90 degrees, they are called complementary angles. Similarly, if the sum of two angles is 180 degrees, they are called supplementary angles.

We are given an angle of 43 degrees. Its complementary angle is 90° - 43° = 47°, and its supplementary angle is 180° - 43° = 137°.

The complement is 47° and the supplement is 137°.

LCM is 240

GCF is 6

long explanation

Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor.

LCM(a,b) = ( a × b) / GCF(a,b)

We will now calculate the prime factors of 30 and 48, than find the greatest common factor (greatest common divisor (gcd) of the numbers by matching the biggest common factor of 30 and 48.

Step-1: Prime Factorization of 30

30 = 2^1 × 3^1 × 5^1

Step-2: Prime Factorization of 48

48 = 2^4 × 3^1

Step-3: Factors of 30

1, 2, 3, 5, 6, 10, 15

Step-4: Factors of 48

1, 2, 3, 4, 6, 8, 12, 16, 24

Final Step: Biggest Common Factor Number

We found the factors and prime factorization of 30 and 48. The biggest common factor number is the GCF number.

So the greatest common factor 30 and 48 is 6.

Answer:

[tex]N=0[/tex]

Step-by-step explanation:

Given

[tex]Lost = 2lb[/tex]

[tex]Gained = 2lb[/tex]

Required:

Determine the net weight change

The weight lost will be treated as negation.

So, the net weight change (N) is:

[tex]N=Gained - Lost[/tex]

Substitute values for weight gained and lost

[tex]N=2lb - 2lb[/tex]

[tex]N=0[/tex]

Hence, the net weight change is 0

C because there can't be two different outputs for the same input.

Answer:

Only (-2, 9) is the solution of the equation.

Hence, option 'b' is correct.

Step-by-step explanation:

Given the equation

y = -2x+ 5

Checking the ordered pair (2, -9)

substituting x = 2 and y = -9 in the equation

y = -2x + 5

-9 = -2(2) + 5

-9 = -4 + 5

-9 = 1

FALSE!

L.H.S ≠ R.H.S

Thus, the ordered pair (2, -9) is NOT a solution of the equation.

Checking the ordered pair (-2, 9)

substituting x = -2 and y = 9 in the equation

y = -2x + 5

9 = -2(-2) + 5

9 = 4 + 5

9 = 9

TRUE!

L.H.S = R.H.S

Thus, the ordered pair (-2, 9) is a solution of the equation.

Conclusion:

Only (-2, 9) is the solution of the equation.

Hence, option 'b' is correct.

how where is the graph cause I don't understand that

Answer:

<b = 108 degrees

<c = 36 degrees

<d = 36 degrees

Step-by-step explanation:

The sum of angle in a triangle is 180 degrees

Hence <b + <c + <d = 180

13x-35 + 5x - 19 + 2x + 14 = 180

13x+5x+2x-35-19+14 = 180

20x-40 = 180

20x = 180 + 40

20 x = 220

x = 220/20

x = 11

Get <b

<b = 13x-35

<b = 13(11) - 35

<b = 143-35

<b = 108 degrees

Get <c

c =5x-19

<c = 5(11)-19

<c = 55-19

<c = 36degrees

Get <d

<d = 2x+14

<d = 2(11) + 14

<d = 22+14

<d = 36 degrees

Answer:

The division was incorrectly solved.

Step-by-step explanation:

Given

[tex]\frac{2}{5} / \frac{8}{9} =\frac{5}{2} * \frac{8}{9} =\frac{5*8}{2*9} = \frac{20}{9}[/tex]

Required

Explain why it is wrong

The solution is wrong because the division was incorrectly solved.

When fraction a/b is divided by c/d, the solution is:

[tex]\frac{a}{b}/\frac{c}{d} = \frac{a}{b} * \frac{d}{c}[/tex]

It should be noted that:

[tex]\frac{a}{b}/\frac{c}{d} \ne \frac{b}{a} * \frac{c}{d}[/tex]

The solution to the quotient is:

[tex]\frac{2}{5} / \frac{8}{9} =\frac{2}{5} * \frac{9}{8} =\frac{2*9}{5*8} = \frac{9}{20}[/tex]

Ithink the answer is3420

Answer:

3420

Step-by-step explanation:

When you find 10% of an amount, the decimal point would move left.

e.g 10% of 342 would be 34.2

So to find the original amount, the decimal point would move right, or in simple terms, you would add a zero

342 + 0 ÷ 3420
