What is the total surface area of the figure below?
6 cm
7 cm
13.1 cm
359.1
0 275,1
400
317.1

Answer: 2x2 + 4xy + 4y2 = 0

2 xx + 4xy +  4yy = 0

...xx + 2xy + y*y  + yy = 0

(x + y)^2  + yy = 0

if  x is a constant

... 2yy + 4xy  - 2xy  + xx = 0

(2yy + 4xy + 2xx -2xx) - 2xy + xx = 0

2(y + x)^2 - 2xx - 2xy + xx = 0

2(y + x)^2 - xx - 2xy  = 0

2(y + x)^2 - xx - 2xy  +yy  - yy = 0  

(x + y)^2  + yy = 0

x = i*y  - y

if  x = r cos a

y = r sin a

cos a )^2  + cos a sina  + sin a)^2  +  sin a)^2 = 0

cos a sin a + sin a)^2 = -1

Answer:

x = 93 degrees

Step-by-step explanation:

Answer:

x= 93°

Step-by-step explanation:

the angles are corresponding angles

this means they have the same angle measure.

the bottom one is 93° so that means the other one is 93° as well.

Answer:

2 decimal places

Step-by-step explanation:

just simple count the number of decimal points on both sides

Volume formula is [tex]V = B \cdot h[/tex]

First find the area of the base (hexagon). The area of a hexagon can be found with the formula [tex]A = \frac{1}{2} P\cdot a[/tex] where [tex]a[/tex] is the apothem (line that's perpendicular to a side and connected to the center point) and [tex]P[/tex] is the perimeter.

We already know the length of the apothem (5.7 ft). We also have one side length already (6.58 ft), a hexagon has 6 sides, so [tex]P = 6\cdot 6.58 = 39.48[/tex] ft.

Plug these into the area formula

[tex]A = \frac{1}{2} (39.48)(5.7)[/tex]

Area of the base ([tex]B[/tex]) is 112.52 ft

Now plug into the volume formula using 15.4 ft as the height

Final answer:

[tex]V = 1732.81 ft^3[/tex]

Answer:

Option D

Step-by-step explanation:

McKenzie wants to put the soil in a box with the soil height = (10 - 2) inches

(As she plans to keep 2 inches from the top of the box empty)

Length of the box = 8 inches

Width of the box = 12 inches

Since, soil in the box will get the dimensions same as of the box but the height will be 2 inches less than the box height.

Therefore, volume of the soil = Length × Width × height

V = 8 × 12 × (10 - 2)

Option D will be the answer.

Answer:

x² - 10 + 2x = 2x + 90

x² - 10 + 2x - 2x = 2x - 2x + 90

x² - 10 = 90

x² - 10 + 10 = 90 + 10

x² = 100

square root them both and you get x = 10

 h-2=-2

    h=0

Hey Btw I strongly reccomend you use photomath for your math classes.

Answer:

[tex] \frac{ - 4(h - 2}{ - 4} = \frac{8}{ - 4} \\ h - 2 = - 2 \\ h - 2 + 2 = - 2 + 2 \\ h = 0[/tex]

Mean of bagel

Step-by-step explanation:

Working out each of the statically summaries Given in the option :

Mean of muffin :

Mean = Σx / n

n = sample size

(61 + 20 + 32 + 58 + 62 + 61 + 56) / 7

= 350 / 7

= 50

Mean of bagel :

Mean = Σx / n

n = sample size

(34 + 45 + 43 + 42 + 46 + 72 + 75) / 7

= 357 / 7

= 51

Hence, from the result obtained, we could see that the value of 51 summarizes the mean of bagel.

The volume is Lenght * width * Height

16 * 9 * 9 = 1296 ft cube

Answer:

there are 16 inches of bases

Answer:

1128 Yard²

Step-by-step explanation:

From the question,

The surface area of a triangular prism is

A = bh+H(a+b+c)...................... Equation 1

Where a = First side of the triangular face, b = base of the triangular face, c = the other side of the triangular face, H = heigth of the prism, h = height of the triangular face

Given: a = 15 yard, b = 18 yards, c = 15 yards, h = 12 yards, H = 19 yards.

Substitute these values into equation 1

A = (18×12)+ 19(15+15+18)

A = 216+19(48)

A = 216+912

A = 1128 Yard²

Hence the surface area of the triangular prism is 1128 yard²
