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.

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: 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:

It the statement is true, then the contrapositive is also logically true. If the converse is true, then the inverse is also logically true. If two angles are congruent, then they have the same measure.

converse, inverse, contrapositive.

Step-by-step explanation:

Radius = diameter / 2 = 18/2 = 9 m

Volume = (radius^2 x pi x height)/3  = (9^2 x pi x 26)/3  = 2205.4 m^3

Answer:

[tex]\huge\boxed{V=2204.3m^3}[/tex]

Step-by-step explanation:

The formula of a volume of a cone:

[tex]V=\dfrac{1}{3}\pi r^2H\\\\r-\text{radius}\\H-\text{height}[/tex]

We have:

[tex]2r=18m\to r=\dfrac{18m}{2}=9m\\\\H=26m[/tex]

substitute:

[tex]V=\dfrac{1}{3}\pi(9^2)(26)=\dfrac{1}{3}(81)(26)\pi=(27)(26)\pi=702\pi(m^3)[/tex]

use π ≈ 3.14

[tex]V\approx(702)(3.14)=2204.28(m^3)\approx2204.3[/tex]

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:

5 1/2 blocks

Step-by-step explanation:

Jacob is painting wooden blocks. He has 11\12 of a quart of paint. Each block needs 1\6 of a quart of paint. How many blocks can he paint?

From the above question:

1/6 quart of paint = 1 block

11/12 quart of paint = x

Cross Multiple

1/6 x = 11/12 × 1

x = 11/12 ÷ 1/6

x = 11/12 × 6

x = 11/2 blocks

x = 5 1/2 blocks

Therefore, Jacob can paint 5 1/2 blocks

Step-by-step explanation:

Harold needs 71 tomato plants.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Harold wants to make a tomato patch.

And, It will have 7 long rows of plants, each with 8 plants in the row, and 3 short rows of plants, each with 5 plants in the row.

Now, For the total number of tomato plants Harold needs, we can multiply the number of plants in each row by the number of rows for each section (long and short) and then add the results as,

Hence, the expression for number of tomato plants Harold needs is:

⇒  (7 long rows x 8 plants per row) + (3 short rows x 5 plants per row) Simplifying the expression, we get:

⇒ 56 + 15 = 71

Therefore, Harold needs 71 tomato plants.

Answer:

36.625

Step-by-step explanation:

5*5 = 25

25 + 8 = 33

33 - 11 = 22

22 + 12 = 34

84/32 = 2.625

34 + 2.625 = 36.625

36.625

Have a nice day!

Answer:

36.625 or 293/8

Answer:

Step-by-step explanation:

add up the total people in the survey

7 + 33 + 56 + 42 + 12 = 150

divide 12 by 150 = .08   or 8%

now multiply .08 * 100,000 = 8,000

Answer:

Alison is most likely to get elected

Step-by-step explanation:

Three friends Alison Beth and Cat are standing for school captain. The probability of Alison get elected is 3/8. The probability that Alison or Cat elected is 7/10.Who is most likely to get elected?

The formula is given as:

p(A or C) = p(A) + p(C)

Where

A = Allison

C = Cat

Step 1

Finding the probability of Cat been elected

Hence,

7/10 = 3/8 + P(C)

P(C) = 7/10 - 3/8

Lowest Common Denominator = 40

P(C) = 13/40

Step 2

Converting both probabilities to decimals

P(A) = 3/8 = 0.375

P(C) = 13/40 = 0.325

Alison has the highest likely probability of getting elected

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:

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 Step-by-step explanation:

Word (story) problems are easy if you use a table to translate the words to precise, concise math variables and operations.  For example,

      Is means                =

    Larger than                                   +

     Four times a                           4*a

    F is 550 less than S                F = S – 550

      Total of A, B, C                       A + B + C  

This seems obvious – until you get stuck on a word problem.  So,

 “the first company” ,  “a second company”      becomes       Let their costs be F and S

                                                                                                 Let K be the number of kilograms

  “$20 to ship a medium box, plus an additional $2 per kilogram”           F =  $20 + 2*K

   “10 for the same size of box, plus an additional $3 per kilogram”           S  =  $10 + 3*K

  “the two shipping methods will cost the same amount”                               F = S

 “What is that weight?”                                                                             report K

Now, the math:

        F        =        S

  20 + 2K   =   10 + 3K

     $10  =  K

Answer:

angle Lmp=77degrees and angle nmp = 103degrees

m ∠LMP =77 degrees and m ∠LMP = 103 degrees

It is given that Angle LMP=-16x+13

Angle NMP=-20x+23

We have to find m∠LMP and m∠NMP.

What is the sum of pair of linear angles?

The sum of pair of linear angles is always 180 degrees

∠LMP+ ∠NMP=180

-16x+13-20x+23=180

-36x+36=180

-36x=180-36

-36x=144

x=-4

Now substitute value of x in Angle LMP and Angle NMP

Angle LMP=-16x+13 =-16(-4)+13=77 degree

Angle NMP=-20x+23 =-20(-4)+23=103 degree
