Step-by-step explanation:

Any complex number is of the form: $a + bi$ where a is real part and B is imaginary part.

Therefore, in given complex number: $7- \sqrt {3}i$

7 is real part.

$\sqrt {3}$ is imaginary part.

Hence, first two options are correct.

Last two options are incorrect because of the following reasons:

$- \sqrt {3}$ is coefficient of $i$ & not $7- \sqrt {3}$

Given number is a difference of a real number and imaginary number & not a sum of a real number and imaginary number.

I’m so confused help please

lozanna [386]

Answer:

B. 0

Step-by-step explanation:

If you subtract the right side expression and simplify, you get ...

4/5(20x +5) -(16x -2) = 0

16x +4 -16x +2 = 0

6 = 0 . . . . . . . . . . . . false

There is no value of x that will make this true. There are no solutions.

Robert went to the grocery store and purchased cans of soup and frozen dinners. each can of soup has 300 mg of sodium and each f

Paraphin [41]

There are 9 cans of soup and 5 cans of frozen dinner.

The variables used for soup and frozen dinner are x and y respectively.

Step-by-step explanation:

Let,

Soup = x

Frozen Dinner = y

According to given statement of sodium;

300x + 500y = 5200 eqn 1

And,

x + y = 14 eqn 2

$Multiplying\ equation\ 2\ with\ 300\\300(x+y=14)\\300x+300y=4200\ Eqn 3\\$

Subtracting Eqn 3 from Eqn 1;

$(300x+500y)-(300x+300y)=5200-4200\\300x+500y-300x-300y=1000\\200y=1000\\y=\frac{1000}{200} \\y=5$

Putting value of y in Eqn 1;

$300x+500(5)=5200\\300x+2500=5200\\\\Subtracting\ 2500\ from\ both\ sides\ \\300x+2500-2500=5200-2500\\300x=2700\\x=\frac{2700}{300} \\x=9$

There are 9 cans of soup and 5 cans of frozen dinner.

The variables used for soup and frozen dinner are x and y respectively.

Which statement best describes the relation (3, 4), (4, 3), (6, 3), (7, 8), (5, 4)?

snow_lady [41]

Answer:

This relation represent y as a function of x, because each value of x is associated with a single value of y

Step-by-step explanation:

we know that

A function is a relation from a set of inputs (x values) to a set of possible outputs (y values) where each input is related to exactly one output

we have the relation

$(3, 4), (4, 3), (6, 3), (7, 8), (5, 4)$

This relation represent y as a function of x, because each value of x is associated with a single value of y

A rectangular tank 60 cm long and 50 cm wide is /5 full of water. When 24 liters of water are added, the water level rises to th

bija089 [108]

Answer:

The tank is 10cm high

Step-by-step explanation:

Given

$L=60cm$ -- length

$W=60cm$ -- width

$x = \frac{1}{5}$ --- water lever

$Addition = 24L$

Required

The height of the tank

Let y represents the remaining fraction before water is added.

So:

$y + x = 1$

Make y the subject

$y = 1 - x$

$y = 1 - \frac{1}{5}$

Solve

$y = \frac{5 - 1}{5}$

$y = \frac{4}{5}$

Represent the volume of the tank with v

So:

$y * v = 24L$

Make v the subject

$v = \frac{24L}{y}$

Substitute: $y = \frac{4}{5}$

$v = \frac{24L}{4/5}$

$v = 30L$

Represent the height of the tank with h;

So, the volume of the tank is:

$v = lwh$

Make h the subject

$h = \frac{v}{lw}$

Substitute values for v, l and w

$h = \frac{30L}{60cm * 50cm}$

Convert 30L to cm^3

$h = \frac{30*1000cm^3}{60cm * 50cm}$

$h = \frac{30000cm^3}{3000cm^2}$

$h = 10cm$
