A tent in the shape of a triangular prism is made using the following piece of fabric. Find the surface area of the fabric. Show
storchak [24]

Answer:

Surface area = 85.84 ft²

Step-by-step explanation:

Considering the fact that large rectangle  area = 6 x 12 = 72 ft²

Also, the two triangles area => 2(0.5 * base * height) = 2(4 x 3.46 x 0.5) = 13.84 ft²

Hence, the total surface area is

72 + 13.84 = 85.84 ft²

Therefore, the surface area of the fabric is 85.84ft²

If 3x−y=12, what is the value of 8x2y?
ArbitrLikvidat [17]

One approach is to express

8x2y

so that the numerator and denominator are expressed with the same base. Since 2 and 8 are both powers of 2, substituting 23 for 8 in the numerator of 8x2y gives

(23)x2y

which can be rewritten

23x2y

Since the numerator and denominator of have a common base, this expression can be rewritten as 2(3x−y). In the question, it states that 3x−y=12, so one can substitute 12 for the exponent, 3x−y, which means that

8x2y=212

The final answer is A.

There’s actually two questions on here please help me

Problem 7

Time is always an independent variable because time marches on doing its own thing without depending on external forces, or other people/things. Instead, other variables depend on time. In this case, the distance d depends on the independent variable t for time.

If the time goes up by 1 hour, then the distance variable goes up by 3 miles. In short, that tells us his speed is 3 mph.

Answer: Choice A) independent = time; dependent = distance

=================================

Problem 8

Everywhere you see an x, replace it with 9. Then use PEMDAS to simplify

f(x) = 5x - 9

f(9) = 5(9) - 9 ... x replaced with 9

f(9) = 45 - 9

f(9) = 36

Answer: 36
