CAN SOMEONE PLSSS HELP ME! IT’S DUE TODAY. I NEED THE SURFACE AREA AND VOLUME...

Mathematics
1 answer:
aev [14]3 years ago
8 0

Answer:

Surface \ area = 2 (LB + BH + HL) = 2 ((4\times 8)+(8 \times 6) + (6 \times 4))

                                                     = 2(32 + 48 + 24)\\=2(104) \\=208 cm^2

Volume = L \times B \times H = 4 \times 8 \times 6 = 192cm^3

levacccp [35]

Answer:

-2.26 lb

Step-by-step explanation:

Let the dog's initial weight be d.

Then, one year later, the dog weighs 3.73 lb less, and thus weighed d - 3.73 lb.  

During the next year, the dog gained 1.47 lb, so now weighs d - 3.73 + 1.47 lb, or

d - 2.26 lb.  This indicates a total weight loss of 2.26 over these two years.

Can anyone explain how to do this? The answer isn't as important as the explanation. My teacher gave us a video w/o an example l
solong [7]

Answer:

x = 182.53

Step-by-step explanation:

Use trigonometric ratios to find the whole side length (a) adjacent to 20° and the side length (b) adjacent to 57° respectively. Then find the difference. That would give you the value of x. That is: a - b = x

Let's solve.

✍️Finding the whole side length adjacent to 20°:

Opp = 87

Adjacent length = ? = a

\theta = 20

Thus,

tan(\theta) = \frac{opposite}{adjacent}

Plug in the values

tan(20) = \frac{87}{a}

Multiply both sides by a

tan(20) \times a = \frac{87}{a} \times a

tan(20) \times a = 87

Divide both sides by tan(20)

\frac{tan(20) \times a}{tan(20)} = \frac{87}{tan(20)}

a = \frac{87}{tan(20)}

a = 239.03

Finding the side length adjacent to 57°:

Opp = 87

Adjacent length = ? = b

\theta = 57

Thus,

tan(\theta) = \frac{opposite}{adjacent}

Plug in the values

tan(57) = \frac{87}{b}

Multiply both sides by b

tan(57) \times b = \frac{87}{b} \times b

tan(57) \times b = 87

Divide both sides by tan(57)

\frac{tan(57) \times b}{tan(57)} = \frac{87}{tan(57)}

b = \frac{87}{tan(57)}

b = 56.50

Therefore:

x = a - b

x = 239.03 - 56.50

x = 182.53

An artist plans a sculpture by stacking two cubes. Write an algebraic expression the artist can use to find the volume of the sc
vesna_86 [32]

Answer:

V= 2x^3

The volume is 128cm^3

Step-by-step explanation:

Given

Cubes = 2

Sides = 4cm

Required

Determine an expression for its volume

Find the volume

Volume of a cube is:

Volume = x^3

Where x represents the length of a side

So, volume of 2 cubes would be:

V= x^3 + x^3

V= 2x^3

Solving (b): Volume when x = 4

Substitute 3 for x in V= 2x^3

V = 2 * 4^3

V = 2 * 64

V = 128

<em>Hence, the volume is 128cm^3</em>
