Consider the equation:
3+2 = 22 +30
1) Rewrite the equation by completing the square.
Your equation should look like (x + c)2 = d or (x – c)2 = d.

2) What are the solutions to the equation?
Choose 1 answer:
A
x = 1+2
B
x = -1/2
C = 12
D
2 = -1+2

Answer:

B=3

Step-by-step explanation:

30/3=10

the inequality wanted some  thing equal or grater so 30/3=10

Question:

What is the m∠ACB in the circle shown below?

Answer:

45

Step-by-step explanation:

So we know it is less than a right angle and it is not a obtuse angle it is less than 90 degrees. 45 is less, 90 is equal(not what we are looking for) , 120, is greater, and 180 is greater which leaves us to our answer 45.

Answer:

x = - [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

- 9x + 3 = 3x + 9 ( subtract 3x from both sides )

- 12x + 3 = 9 ( subtract 3 from both sides )

- 12x = 6 ( divide both sides by - 12 )

x = [tex]\frac{6}{-12}[/tex] = - [tex]\frac{1}{2}[/tex]

Answer:

N=22.815≈23  

Step-by-step explanation:

SIN N=19/49

N=\sin^{-1}(\frac{19}{49})

N=sin

N=22.815≈23  

Second one is correct, The value of -a - c is positive

See, from the number line a = -6 and c = 2

Now, -a - c

= -(-6) -(2)

= +6 - 2 = 4

Which is true...

Answer:

[tex]\text{A) }190[/tex]

Step-by-step explanation:

Similar to the handshake problem, if every student must talk with another person, each student will talk to 19 other students. However, a conversation consists of two people, so we must divide the number of ways we can rearrange the two people ([tex]2![/tex]). Therefore, our answer is [tex]\frac{20\cdot 19}{2!}=\boxed{\text{A) }190}[/tex]

Answer:

#2 64, 79, 95, 83, 81, 90, 67, 86, 91, 84, 81, 69, 83, 92

Step-by-step explanation:

A stem-and-leaf plot is a detailed graphical presentation of quantitative data on special kind of table that promotes visualizing the individual numbers in the data with the number at the stem being the first digits of the numbers in the data set while the leaf represent the last digit of each number in the data set

Following the above rule, the data in the given stem-and-leaf plot are;

64, 67, 69, 79, 81, 81, 83, 83, 84, 86, 90, 91, 92, 95

Therefore, the set of data that could have been used to create the stem-and-leaf plot is the data set that has all the numbers in the given stem-and-leaf plot which is the data set;

64, 79, 95, 83, 81, 90, 67, 86, 91, 84, 81, 69, 83, 92.

Answer: X = 3

Step-by-step explanation:

5x - 2 = 3x + 4

5x = 3x + 6 (+2 to both sides)

2x = 6

x = 3

Answer: it’s 20m long

Step-by-step explanation:

I can’t explain .—.

Answer:

20 meters

multiply the length by itself then multiply the width by itself then add them together then the square root of the total is the diagonal length.

step-by-step explanation :

16 x 16 = 256

12 x 12 = 144

256 + 144 = 400 sq rt = 20

Answer. The diagonal length is 20 meters

Answer:

1.33cm

Step-by-step explanation:

if 2cm is representing 75 miles, that means that .66 (repeating) is representative of 25 miles. This is because .66 (repeating) times 3 is equal to 2, and 25 times 3 is equal to 75. The reason 1.33cm would be equal to 50 miles is because if 25 miles is equal to .66, and 50/25 = 2, then you would have 2x.66 (repeating), to get 1.33.

Answer:

A. Parallelogram LMNP

B. 33

C. 98°

Step-by-step explanation:

LMNP is a parallelogram.

Adjacent angles of a parallelogram are Supplementary.

[tex] \therefore 82\degree +(3x - 1)\degree =180\degree [/tex]

[tex] \therefore (3x - 1+82)\degree =180\degree [/tex]

[tex] \therefore (3x +81)\degree =180\degree [/tex]

[tex] \therefore 3x +81 =180 [/tex]

[tex] \therefore 3x =180-81 [/tex]

[tex] \therefore 3x =99 [/tex]

[tex] \therefore x =\frac{99}{3} [/tex]

[tex] \therefore x =33 [/tex]

[tex] \implies m\angle N= (3x - 1)\degree=(3*33 - 1)\degree=(99-1)\degree = 98\degree [/tex]

[tex] \because m\angle L =m\angle N[/tex]

(Opposite angles of a parallelogram)

[tex] \therefore m\angle L =98\degree [/tex]

Answer:

1 no the quadilateral is parallelogram

2 no .82+82+3x-1+3x-1=360

162+6x=360

6x=198

x=198/6

x=33

3 no angle L =3x-1(opposite angles of a parallelogram are equal)

3*33-1

99-1

98

Answer:

Pleaseee post the question clearly

Answer:

a.

radius [r]=breadth[b]=4in

length [l]=7in

now

[C]area 1/4 th circle +area of 1/4th circle= semi circle =1/2×πr²h=1/2×π×4²=8πin²=25.13in²

area of rectangle [A]=l×b=7×4=28in²

total area =A+C=28in²+25.13in²=53.13in²

Step-by-step explanation:

b.

height [h] of triangle =12-4=8cm

base[b] of triangle= 12-3.5-3.5=5cm

area of triangle [A]=1/2×b×h=½×8×5=20cm²

again

length of square [L]=12cm

area of square [S]=L²=12²=144cm²

Area of shaded region=S-A=144-20=124cm²

Answer:

an equilateral triangle

Step-by-step explanation:

A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees

Area of a triangle = 1/2 x base x height

the perimeter of a triangle = sum of the side lengths

An equilateral triangle is a triangle with three equal sides. the distance travelled her all equal to 10 miles.

Answer:

Below

Step-by-step explanation:

First, find the difference. You would do

-19 - (-9) = -10

-9 - 1 = -10 and so on...

The difference is -10

Now you need to find what number will make 11 when added to -10.

11 - (-10) = 21

The equation:

y = -10x + 21

Answer:

[tex]V=0.09375\ mm^3[/tex]

Step-by-step explanation:

Given that,

The length of the rectangular prism = (1/2) mm

Width = (1/4) mm

Height = (3/4) mm

We need to find the volume of the prism. We know that the formula for the volume of a rectangular prism is given by :

V = lbh

Put all the values,

[tex]V=\dfrac{1}{2}\times \dfrac{1}{4}\times \dfrac{3}{4}\\\\V=0.09375\ mm^3[/tex]

So, the volume of the prism is equal to [tex]0.09375\ mm^3[/tex].

Answer:

[tex]9\pi -18[/tex]

Step-by-step explanation:

Explanation:

This can be proven by dividing the parallelogram into two triangles, and then proving the triangles congruent (use ASA). Once you know the triangles are congruent, then the corresponding pieces must be congruent as well. The corresponding pieces being the same length tells us that the opposite sides of a parallelogram are always congruent.
