Answer:

8i + 4

Step-by-step explanation:

Add/subtract like terms:

7 - 3

= 4

-4i - (-12i)

-4i + 12i

= 8i

Add these together:

8i + 4

So, the simplified expression is 8i + 4

Answer:

Area of semi-circle = [tex]\frac{1}{2}\pi r^{2}[/tex]

Perimeter of semi-circle = [tex]\pi r + 2r[/tex]     where r is the radius

Step-by-step explanation:

Pi has been used in the construction of arches, bridges, churches and buildings.

Since the bridges and arches are semicircles, Pi helps in determining perimeter of the semicircle which in turn helps in calculating the amount of material required for construction.

Area of semi-circle = [tex]\frac{1}{2}\pi r^{2}[/tex]

Perimeter of semi-circle = [tex]\pi r + 2r[/tex]     where r is the radius

Answer:

18

Step-by-step explanation:

Take the 54. The cake reduces her size by 1/3 so you multiply 54*1/3 to get 18 inches or 1.5 feet tall. :)

Answer:

C. 1.3

Step-by-step explanation:

0, 0, 0, 0, 1, 1, 1, 2, 2, 2, 3, 4

To find the mean, or average, we add up all the numbers to get the total number of siblings (16), and divide by the number of classmates she surveyed (12). 16/12 = 1.3

Please LMK if you have questions. Have a good day.

Answer:

A. 24

Step-by-step explanation:

n Over 54 EndFraction = StartFraction 4 Over 9 EndFraction

n/54 = 4/9

Cross product

n * 9 = 54 * 4

9n = 216

n = 216/9

n = 24

A. 24

Check:

n/54 = 4/9

24 / 54

Divide through by 6

= 4/9

Before they performed his initial experiment, Milgram examined both a Yale undergraduate panel as well as a psychology panel. In all of these polls, the majority of the people expected which less than 1 percent will go to 450 volts, that's why Milgram subsequently surveyed the respondents and found 84% happy they had taken part, but only 1% regretted their participation.

Answer:

(-3-1)^2+(0+3)^2=r^2

radius is 5 units

Step-by-step explanation:

(x-h)^2+(y-k)^2=r^2

We know values of all variables except r at the moment.

h is the x-coordinate of the center of the circle, and k is the y-coordinate.

x and y are coordinates of a point the circumference touches.

From there, just plug in the numbers and solve!

Answer:

x = -3

Step-by-step explanation:

using the slope formula y2 - y1/x2 - x1 = 1 so

-6 - 1 / x - 4 = 1, so -7/-7 = 1 so x has to be -3 to make the bottom = -7

Answer:

x = 4

Step-by-step explanation:

2(8x) = 64

x = 4

Step-by-step explanation:

Answer:

0.5

Step-by-step explanation:

how you would solve this is 5 plus 3 plus 2 which will equal 10 (this ten will be your denominator) after that you look at how many blue sections there are (5). so 5 out of 10 of them are blue so your fraction would be 5/10. then you will reduce the fraction to 1/2. the question wants you to put this in decimal form so you will divide the 1 by 2 so in decimal form this is 0.5.

Answer:

24-5^2

Step-by-step explanation:

hope this helps

Answer:

1/5

Step-by-step explanation: First, turn 1/2 so that the denominator is the same as the other fraction (multiply both by 5 to get 5/10). Now subtract to get 2/10. Then, divide both by 2 to get the fraction in the simplest form.

Answer:

2(2t+3)

Step-by-step explanation:

Given the expression;

5t + 10 - 4 - t

Combining the like tems;

5t - t + 10 - 4

= (5t-t) + (10-4)

= 4t + 6

Factor out 2

= 2(2t+3)

This gives the required expression

Answer:

4t+6

Step-by-step explanation:

Answer:

x=17°

Step-by-step explanation:
