drag each tile to the correct box. not all tiles will be used. one solution each is given for four quadratic equations. assuming
saw5 [17]

for the equation is, x = -4 - 5i

The  solution will be, x = -4 + 5i

for the equation is, x = 4 + 5i

The  solution will be, x = 4 - 5i

for the equation is, x = 5 - 4i

The  solution will be, x = 5 - 4i

<h3>Quadratic equation defind as:</h3>

Any equation in algebra that can be written in proper format as where x stands for an unknown, where a, b, and c stand for known numbers, and where a 0

<h3>According to the given information:</h3>

If (a + bi) is a complex number and a quadratic equation has one solution,

The second solution to the equation will be the conjugate of the first.

Consequently, the alternative solution will take the form of (a - bi).

for the equation is, x = -4 - 5i

The  solution will be, x = -4 + 5i

for the equation is, x = 4 + 5i

The  solution will be, x = 4 - 5i

for the equation is, x = 5 - 4i

The  solution will be, x = 5 - 4i

sertanlavr [38]

Answer:

$140

Step-by-step explanation:

Total Amount of chocolate = 100 Pounds

Amount of chocolate in one box = 1 1/4 Pounds =  5/4 Pounds

Number of boxes = 100/(5/4) = 80 boxes

Cost of one box = $1.75

Total selling price = 80×1.75 = 140

The total selling price for all the boxes of chocolate is $140

If 48 feet are represented by 12 inches on a scale drawing, then a scale of 1/4 inch represents how many feet? a. 3 foot c. 2 fo
alukav5142 [94]
Hello there!

Math is hard! So we as students, we need to play the smart game with Math in order to find the easiest way to solve the problems. What do I mean? Well as you can see they gave us Fraction which won't be easy! So we will transform the fractions into decimals. So let's get started.

Then a scale of 1/4. Transformed into decimal = Then a scale of 0.25
So instead of using the fraction 1/4, I used its decimal 0.25

So if:

48 feet ......> 12 inches
x feet ........> 0.25 inches

Cross multiply

12 * x = 0.25 * 48

12x = 12
Divide both sides by 12
12x/12 = 12/12

x = 1

The correct answer is option D, 1 foot

I hope this helps! Please let me know if you have any question.

Thanks!

Evan used base-10 blocks to model the product of 3 and 0.51.
Lilit [14]

Base 10 blocks are used to perform arithmetic operations.

To model the product of 3 and 0.51, Evan needs <em>3 copies of 5 tenths and 1 hundredths.</em>

The expression can be represented as:

\mathbf{3 \times 0.51}

Express 0.51 as 0.5 + 0.01

\mathbf{3 \times 0.51 = 3 \times (0.5 + 0.01)}

  • 0.5 means 5 tenths
  • 0.01 means 1 hundredths
  • 3 means that, the above blocks are needed in three places.

Hence, Evan needs <em>3 copies of 5 tenths and 1 hundredths.</em>
