Answer:

c = 8

Step-by-step explanation:

d=(r-c) t=?

20=(13-c)4=?

(13-c) * 4/ 4 =20/4

13-c=5

13-c-13=5-13

-c= -8

-c/-1 = -8/-1

answer is c=8

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:

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°)

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

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:

<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:

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.

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°.

Answer:

4. His classmate's daily allowance is of P100.

5. She used 25% of the sheets of art paper.

Step-by-step explanation:

4. Manuel, a son of a school janitor, does not ask for more. He has a daily

allowance of P10 a day which is 20% of his classmate's daily allowance. How much is his classmate's daily allowance?

An allowance of P10 a day is 20% of his classmate's allowance, that is, 20% of x. So

[tex]0.2x = 20[/tex]

[tex]x = \frac{20}{0.2}[/tex]

[tex]x = 100[/tex]

His classmate's daily allowance is of P100.

5. Carla, a grade six pupil , has 24 sheets of art paper for his project in Math. If 6 sheets of art paper were used by Carla, what percent of the sheets of art paper did she use?​

She used 6 sheets, of the 24. So

[tex]P = \frac{6*100}{24} = \frac{100}{4} = 25[/tex]

She used 25% of the sheets of art paper.

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

Answer: x>75

Step-by-step explanation:

Simplifying both sides of the inequality then isolating the variable

Answer:

x = -22

Step-by-step explanation:

first you distribute the 1/3 to x and -10 and get

1/3x - 10/3 = -4

then add -10/3 to both sides and get

1/3x = -22/3

then divide both sides by 1/3 and get

x = -66/3

(-66/3 simplified is -22)
