multiplying two complex numbers involves _____

Answer:

The new cost is $108.98

Step-by-step explanation:

Mark up is the amount that is added to cost price of a product for profit.

Given

Cost price of boots = C = $99.99

Mark up = 9%

First of all we will calculate markup and then add it to the cost price of boots to find the new cost.

[tex]Mark\ up = M = 9\%\ of\ 99.99\\= 0.09*99.99\\=\$8.99[/tex]

The new cost will be:

[tex]C_n = Cost\ price + mark\ up\\C_n = 99.99+8.99\\= 108.98[/tex]

The new cost is $108.98

Step-by-step explanation:

0.428

(.43)

Answer: A.82

have: x + 105 + x + 89 = 180

⇔ 2x + 194 = 180

⇔ 2x = 180 - 194 = -14

⇔ x = -14/2 = -7

=>  the measure of the angle is -7 + 89 = 82

Answer:

62.4 meters

Step-by-step explanation:

1 millimeters to 0.001 meters

62400 * 0.001 = 62.4

Answer:

0.624m

Step-by-step explanation:

62400mm in cm is 62.4cm

there is 100cm in a meter so you don't have a total of 1m

therefore you divide it by 100 after you convert to cm

Answer:

-12w+7

Step-by-step explanation:

because you have to combined like terms

We can prove that these triangles are congruent by using SAS congruency rule.

SAS which means Side Angle Side.

In these triangles, we see that two sides are equal in length and one angle is equal.

So, SAS congruency rule is the answer.

Answer:

62

Step-by-step explanation:

180-56=124

124/2= 62

62+62+56=180

Answer:

x = 62 degrees

Step-by-step explanation:

This is an isosceles triangle from the two lines drawn. This means that the other angle is also x degrees.

we know a triangle is 180 degrees total and this triangle has a 56 degree for one angle and for the two other angles they have the same value.

This means

180 = 56 + x + x

180 = 56 + 2x

180-56 = 2x

124/2 = x

x = 62

Answer:

     x  = z  = 70°

        y = 110°

Step-by-step explanation:

From the diagram, we have 4 angles;

To find y;

       110° and y are vertically opposite angles so they are equal.

 So, y  = 110°

Also, y and x lie on a straight line. Sum of angles on a straight line is 180°;

         y + x  = 180

        110 + x = 180

             x  = 180-110  = 70°

Also, x and z are vertically opposite angles and they are equal;

       x  = z  = 70°

        y = 110°

Answer:

y= 2x-5

Step-by-step explanation:

I just plugged the information into the formula.

Answer: x=10

Step-by-step explanation: it is because 19x-10=180 so that means that x=10

Answer:

14

Step-by-step explanation:

The given expression is 3x - 8y. The given values for x and y are 10 and 2, respectively. So, input the values of x and y into the expression:

3(10) - 8(2)

30 - 16

14

The value of the expression is 14.

Step-by-step explanation:

Answer:

1a. 9a+6c=132

1b. There were 8 adults

2a. 4b+3v=152

2b. There are 32 students on each bus

Step-by-step explanation:

Answer:

1 a.   $132= 9a + 6c

1b.  8 adults

2a. 152= 4b + 3v

2b. 32 students per bus

Step-by-step explanation:

1b. 132= 9a +60,  so 132 subract 60 = 72, then divide by 9, so 72/9= 8 adults

2b. 152=4b + 24, so 152 subract 24 =128, then divide by 4, 128/4= 32 students per bus

Answer:

The answer is corresponfing angles theorem

Answer:

The answer is y= −6

Step-by-step explanation:

Let's solve your equation step-by-step.

10−5y=2(14−y)

Step 1: Simplify both sides of the equation.

10−5y=2(14−y)

10+−5y=(2)(14)+(2)(−y)(Distribute)

10+−5y=28+−2y

−5y+10=−2y+28

Step 2: Add 2y to both sides.

−5y+10+2y=−2y+28+2y

−3y+10=28

Step 3: Subtract 10 from both sides.

−3y+10−10=28−10

−3y=18

Step 4: Divide both sides by -3.

−3y/−3=18/−3

y=−6

Answer:

y=−6

Answer:

y= -6

Step-by-step explanation:

10-5y=2(14-y)

10-5y=28-2y

10-5y+2y=28

-3y=28-10

-3y=18

y= -6

Answer: 3x + 1 = 7 (combine like terms)

3x = 6 (divide by 3)

X =2

Step-by-step explanation:

In answer

Answer:

[tex]x=2[/tex]

Step-by-step explanation:

[tex]3x+1= 7[/tex]

[tex]3x = 6\\ \[/tex]             Subtract both sides by 1.

[tex]\frac{3x}{3} = \frac{6}{3}[/tex]             Divide both sides by the coefficient.

[tex]x = 2[/tex]

Check your work:

[tex]3x+1=7 \\ 3(2)+1=7[/tex]      

[tex]6+1=7\\7=7[/tex]        

[tex]x=2[/tex]

Answer:

a>-21(1/3)

Step-by-step explanation:

3/4a>-16

first thing is to divide both sides by 3/4 to isolate the variable.

Since it is not negative, the sign stays the same.  

-16/0.75=-21.3 repeating or just 1/3

Answer:

Step-by-step explanation:

volume of box = 56 ft³

base = 4

width = 1/2

height = ?

volume = base x width x height

56 = 4 x 0.5 x h

56 = 2h

h = 56 / 2

h = 28

therefore, the height of the box is 28 ft
