Answer:

so I just tried to find the mean (average) and it was: 6.3

Answer:

Step-by-step explanation:

The formula is P= a+b+c+d

a=base

b=base

c=side

d=side

Please search perimeter of a trapezoid.  It will provide the answer.

Answer:

Perimeter = 19.77 units

Step-by-step explanation:

Perimeter = AB + BC + CD + AD

BC = 5

AD = 8

AB² = 2² + 3² = 4 + 9 = 13

AB = √13 = 3.61

CD² = 1² + 3²  = 1 + 9 = 10

CD = √10 = 3.16

Perimeter = 3.61 + 5 + 3.16 + 8 = 19.77

Step-by-step explanation:

Answer:

The length is 8 ft.

The width is 2 ft.

Step-by-step explanation:

A = l*w

l = w + 6

16 = w(w + 6)

16 = w^2 + 6w

w^2 + 6w - 16 = 0

(w + 8)(w - 2) = 0

w = -8ft or 2ft

Since lengths cannot be negative in reality, w = 2ft.

l*2 = 16

l = 8ft

Answer:

C

Step-by-step explanation:

400*.035 = 14 *2 = 28

250*.0325 = 8.125 *2 = 16.25

28 + 16.25  = 44.24

44.25+650 = 694.25

Answer:

C

Step-by-step explanation:

What is the lowest common multiple

6 = 2 * 3

8 = 2 * 2 * 2

LCM = 2 * 2 * 2 * 3

LCM = 24

So you just divide 6 and 8 into 24. The result will be the number of packages.

Cups: 24/6 = 4

Plates: 24/8 = 3

You need 4 packs of cups and 3 of plates

Answer: 3:35

Step-by-step explanation:

Answer:

25.5

Step-by-step explanation:

Add 7.1 to each side

[tex]w-7.1=18.4[/tex]

   [tex]+7.1[/tex]     [tex]+7.1[/tex]      add 7.1 on both sides, 7.1s will cancel out on the left side.

___________     solve for 18.4 + 7.1, which is 25.5

[tex]w=25.5[/tex], final answer.

Step-by-step explanation:

Answer:

1,100

Step-by-step explanation:

15*10*2=300

20*15*2=600

20*10=200

300+600+200=1,100

you need to find the surface area which means the area of all the sides except the top(bc i think its open???)

a shortcut i used was multiplying sides that have the same area by 2. for example, the side 15*10, there was another side like that, so i multiplied by two instead of having to solve for the other side individually, does that make sense?

check my math if im wrong

Answer:

area of right triangle = ab/2

                     base = 18yards

                    height = 2 1/3 = 7/3yards

area =  (18 * 7/3) /2 = 42 /2 = 21[tex]yards^{2}[/tex]

hope this answer helps you.....

Answer:

Anne

Step-by-step explanation:

Let's solve it by replacing x by 5, then -5.

(5+5)2=0

10*2=0

20=0

(-5+5)2=0

-5 and 5 cancel each other out, and 0 times anything is 0.

0=0

So Anne is correct.

Answer:

perimeter of trapezium =sum of all sides

perimeter of trapezium =10cm+6cm+12cm+8cm

perimeter of trapezium =36cm

perimeter of semicircle =pi×r

perimeter of semicircle =3.14×6cm

perimeter of semicircle =18.84cm

perimeter of the figure =36cm+18.84cm=54.84cm

The height of the monument is 30 meters.

We have,

Let's assume the height of the monument is "h" meters.

From the top of the building, the angle of elevation to the top of the monument is equal to the angle of depression to the foot of the monument. This forms a right triangle with the building, the monument, and the ground.

In this triangle, the opposite side of the angle of elevation is the height of the building, which is given as 30 meters.

The opposite side of the angle of depression is the height of the monument, which is "h" meters.

Since the angles of elevation and depression are equal, the triangle is an isosceles triangle.

Therefore, the opposite sides are equal in length.

By setting up the equation:

h = 30

Thus,

The height of the monument is 30 meters.

Answer:

x = 0

y = 1

z = -4

Step-by-step explanation:

6x + 4y + 1z = 0 => z = -6x -4y

If 12x - 4y - 5z = 16, then

12x - 4y - 5(-6x - 4y) = 16

12x - 4y + 30x + 20y = 16

42x + 16y = 16 => 21x + 8y = 8

then y = (8 - 21x)/8

if -24x - 4y + 5z = -24

-24x - 4y + 5(-6x -4y) = -24

-24x - 4y - 30x - 20y = -24

-54x - 24y = -24 => -9x - 4y = -4

substitute y = (8 - 21x)/8

then -9x - 4(8 -21x)/8 = -4

-9x - 1/2(8 -21x) = -4

times 2 in both side

-18x - (8 - 21x) = -8

-18x - 8 + 21x = -8

3x = -8 + 8

3x = 0

x = 0

then y = (8 - 21x)/8 = (8 - 21(0))/8 = (8 - 0)/8 = 8/8 = 1

then z = -6x -4y = -6(0) - 4(1) = 0 - 4 = -4
