2. 9 + 11i

Step-by-step explanation:

first problem:

first, we rewrite it and remove the parentheses.

12 - 3i + 7 + 3i

then, just remove the opposites and calculate.

Answer:Alexia swam  7,560meters in 2 weeks

Step-by-step explanation:

Step 1

7 days = 1 week

therefore 2 weeks = 7 x 2 = 14 days

Step 2

Each day  Alexia swam =  0.54 kilometres

So in 14 days( 2 weeks) She swam = 14 x 0.54 km= 7.56km

Answer is needed in meters

so 1000 m = 1km

Therefore 7.56 km = 7.56km x 1000=7,560meters

Answer:

Step-by-step explanation:

The length of the expert trail is 800 meters. We can find our answer by using given tape diagram and simple mathematical calculations.

What is tape diagram?

A tape diagram is a visual model resembling a piece of tape, that is used to assist with the calculations of ratios and addition, subtraction and commonly multiplication.

Here,

Length of the Beginner trail is 200 meters

And also expert trail is 4 times to Beginner trail.

So, Expert trail = 4 * Length of beginner trail.

     Expert trail = 4* 200

                        = 800 meters.

Hence, we get the answer.

Answer:

21,200

Step-by-step explanation:

Votes casted = 53000

Votes received = 3/5

Votes did not receive = 1- 3/5 = (5-3)/5 = 2/5

Total votes not received by winner

= 53000 *2/5

= 10,600 * 2

= 21,200

Answer:

[tex]\%Percent = 28\%[/tex] ---- Before Lunch

[tex]\%Percent = 72\%[/tex] --- After Lunch

Step-by-step explanation:

Given

[tex]Total = 134[/tex]

[tex]Before\ Lunch = 38[/tex]

[tex]After\ Lunch = 96[/tex]

Required

Determine the percentage of students seen in both cases.

This percentage is calculated by dividing the number of students seen by the total number of students. Then multiplied by 100%

i.e

[tex]\%Percent = \frac{Seen}{Total} * 100\%[/tex]

- Before Lunch;

[tex]\%Percent = \frac{Before\ Lunch}{Total} * 100\%[/tex]

[tex]\%Percent = \frac{38}{134} * 100\%[/tex]

[tex]\%Percent = \frac{3800\%}{134}[/tex]

[tex]\%Percent = 28\%[/tex] --- approximated

- After Lunch;

[tex]\%Percent = \frac{After\ Lunch}{Total} * 100\%[/tex]

[tex]\%Percent = \frac{96}{134} * 100\%[/tex]

[tex]\%Percent = \frac{9600\%}{134}[/tex]

[tex]\%Percent = 72\%[/tex] --- approximated

Answer:

A: 336 km

B: 14 L

Step-by-step explanation:

Use a proportion

210 km / 5 L = x / 8L         Cross multiply

8*210  = 5 x

1680  = 5x

x = 1680 / 5

x = 336 km

===============

210 /5 = 588/x                   Cross multiply

210x = 588 * 5

210x = 2940                     Divide by 210

x = 2940/210

x = 14 L

Answer:

A) -10°F

Step-by-step explanation:

Given that:

Boiling point of water gets affected when there is a change in the elevation.

Expression to represent the temperature i.e. boiling point w.r.to altitude [tex]A[/tex] is given by the equation:

Temperature in [tex]^\circ F[/tex] = [tex]\frac{-2A}{1000}[/tex]

Given that, the altitude, [tex]A[/tex] = 5,000 feet

To find:

The number of degrees Farenhite at which the boiling point of water will change.

Solution:

Here, we are given the expression:

Temperature in [tex]^\circ F[/tex] = [tex]\frac{-2A}{1000}[/tex]

And value of altitude, [tex]A[/tex] = 5,000 feet

Let us put the value of [tex]A[/tex] in the equation and let us find the value of temperature in [tex]^\circ F[/tex].

Temperature in [tex]^\circ F[/tex] =

[tex]\frac{-2\times 5000}{1000}\\\Rightarrow -2\times 5\\\Rightarrow \bold{-10^\circ F}[/tex]

Therefore, the answer is:

A) -10°F

Answer:

$162

Step-by-step explanation:

you divide 6 months by 2 then you divide 108 by 2 then you add the half of 108 and plus it to 108 then you get your total.

The function of the length of time you have been taking classes is f(x) = 15x and cost for 9 months is $135

A unit rate means a rate for one of something.

Given that, You are taking a TAE Kwan Do class that costs $15 a month. In addition, you needed to purchase a uniform. You paid a total of $108 after 6 months.

We have unit rate = $15 per month

Since, one month cost is $15 therefore, for 6 months = 15×6 = $90

Therefore, cost of uniform = $108 - $90 = $18

Let you are taking classes for x months, the function of the length of time you have been taking classes,

f(x) = 15x

For 9 month cost =

f(9) = 15×9 = 135

Hence, the function of the length of time you have been taking classes is f(x) = 15x and cost for 9 months is $135

Answer:

d + 85

Step-by-step explanation:

Look at it like this,

suppose you have 1 DVD, and the mother buys 85 DVDs then you have 1 + 85 = 86 DVDS

or when you have 2 DVDs, then you have 2 + 85 = 87 DVDs afterwards.

notice that you always take the number of DVDs you already have, and add 85 to it.

d is just a number, but you just don't know it yet. you can change d by any number, and you know d+85 is the number of DVDs afterwards

Step-by-step explanation:

Radical Expressions

Melissa multiplied [tex]\sqrt{a}[/tex] and [tex]\sqrt{b}[/tex] and got a rational number.

We are also given that a and b are both natural numbers. It means their product must be not only rational but also a natural number.

We can write that product like:

[tex]\sqrt{a} \cdot \sqrt{b}=\sqrt{a\cdot b}[/tex]

If the result is a natural number, then the product of a and b must be a perfect square. so the radical disappears.
