Answer:
i=3/4
Step-by-step explanation:
Assuming that we are treating "i" as a variable and not the constant "i":
12+2i-i=9i+6
12+i=9i+6
12=8i+6
6=8i
8i=6
i=6/8
i=3/4
Therefore, the equation has only one real solution which is i=3/4

Which is a simplified form of the expression -3p – 4 + 4p + 8?
A. -p - 4
B. 2p - 4
C. p + 4
D. 7p + 4
Answer:
C
Step-by-step explanation:
-3p – 4 + 4p + 8
Simplify by combining like terms
-3p + 4p = p
-4 + 8 = 4
The expression in it's simplest form would be p + 4
Answer:
The answer is C.
Step-by-step explanation:
-3p - 4 + 4p + 8 can be grouped into:
-3p + 4p - 4 + 8.
If you add the p's together and the numbers together, your answer should be:
p + 4.
What is the surface area of the cylinder shown? Use 3.14 for pie. 4cm for the Radius, and 9cm for the height.
==============================================
Work Shown:
SA = 2*pi*r^2 + 2*pi*r*h
SA = 2*3.14*(4)^2 + 2*3.14*4*9
SA = 326.56
Notes:
The answer is approximate. Use more decimal digits of pi to get a more accurate answer (though it will never be exact unless you leave it in terms of pi).The portion 2pi*r^2 is the fact we have two circular bases with area of pi*r^2 each.The portion 2*pi*r*h is the lateral area, or the area around the curved side. If you unfold this portion, as you would maybe a label on a soup can, it has base of 2*pi*r and height h. The base 2pi*r is the circumference of the circle of radius r.Answer:

help finding the volume
Answer:
1651.06 m³
Step-by-step explanation:
the volume of the whole block is base area times height :
Vb = 10 × 12 × 18
but we have to deduct the volume of the removed central cylinder.
the volume of the cylinder is again base area times height :
Vc = pi×r² × 18 = pi×3² × 18 = pi×9×18
so, the volume of the object is
V = Vb - Vc = 2160 - 508.94 = 1651.06 m³

If f (x) = -2x2 + 6, find f (-3).
Answer:
Step-by-step explanation:
Answer:
f(- 3) = - 12
Step-by-step explanation:
To find f(- 3) substitute x = - 3 into f(x) , that is
f(- 3) = -2(- 3)² + 6 = -2(9) + 6 = - 18 + 6 = - 12

A wooden board has a volume of 0.225 cubic m and a mass of 146.25 kilograms.
What is the density of the board?
Answer:
650 kg/m³
Step-by-step explanation:
The density is the ratio of mass to volume. The volume is the product of the dimensions of the prism.
density = (146.25 kg)/((1.5 m)(0.75 m)(0.2 m)) = 146.25/0.225 kg/m³
= 650 kg/m³

Quandrilateral ABCD is inscribed in a circle. What is the measure of angle A? A=(2x-40)B 116 C D=x what is the measure of angle A
Answer:
angle A = 88°
Step-by-step explanation:
Given: inscribed quadrilateral ABCD
(recall that inscribed quadrilaterals have opposite angles supplementary.
A=2x-40
B=116
D=x
From inscribed quadrilateral,
B+D=180 => 116+x = 180 => x=64
A=(2x-40) = 2*64-40 = 88°
(C = 180-88 = 92°)

Answer:
10
Step-by-step explanation:
10 is the greatest common factor that you can divide into both 40 and 50.
Answer:
10
Step-by-step explanation:
Try and find the prime factorization of 40 and 50.
40=2*2*2*5
50=2*5*5
Multiply the prime factors that are common to both numbers.
2*5=10
The circular rug is placed on a square floor. The rug touches all four walls. How much of the floor space is not covered by the rug?
Answer:
42 ft
Step-by-step explanation:
14 times 14=196
R of circle =7
7 squared=49
49 times pi= 153.938040026
196-153.938040026= 42.0619599741
Rounded to 1 decimal=42.1
Rounded to whole number = 42

Your cousin Pablo gets his haircut, and it costs $12.00. What will he spend in total on his haircut if he includes a 12% tip?
Answer:
The tip would be $1.44, so the total would be $13.44
Step-by-step explanation:
To find the tip you take the bill ($12), and multiply it by the percent of tip given (12%), but it has to be in decimal form. 12% in decimal form is .12. 12 times .12 is 1.44. Add $12 to that to get $13.44.
Answer:
Step-by-step explanation:
You could do this a couple of ways. The first and easiest is to change 12% to a decimal. 12% = 12/100 = 0.12
Add this onto 1.
1 + 0.12 = 1.12
Multiply this number by
12*1.12 = 12(1 +0.12) Remove the brackets
12*1 + 1.44
Haircut + tip = 13.44
Of course, it would be much shorter to do it 12*1.12 = 13.44

What's for Lunch2
Marcia Amidon Lusted
Zachary Maxwell was tired of trying to explain to his parents why he wanted to bring lunch to school
instead of eating hot lunch. They couldn't understand why he didn't want to eat the gourmet food
described on the school's online menu, which sounded both nutritious and interesting. Zachary just
couldn't convince them that the food wasn't as great as it sounded. So in the fall of 2011, he began
sneaking a small video camera into the cafeteria at his school, to show his parents what the lunches
were really like. Six months and 75 school lunches later, Zachary made a documentary film about his
lunch called Yuck A 4th Grader's Short Documentary About School Lunch
Did the student who made this film provide an objective opinion? Did that affect the quality of the film?

Answer:
g = [tex]-\frac{2x}{3} -1[/tex]
Step-by-step explanation:
Divide each term by -3 and simplify.
[tex]g(x)=\frac{2x}{-3} +\frac{3}{-3}[/tex]
[tex]g(x)=-\frac{2x}{3} -1[/tex]
The negative sign has to go in the whole number position
3/ -3 = -1 so the addition sign no longer exist since 1 is negative
