Figure 1: find the surface area: [(3 x 2 1/4) x 2] for the top and bottom. [(4 1/2 x 2 1/4)x 2] for the left and right squares. [(3 x 4 1/2) x 2] for the front and back. Which should be 20 1/4 + 27 + 13 1/2 = 60 3/4 m. The area is 4 1/2 x 3 x 2 1/4 = 30 3/4 m.

HELP PLEASE!!!!!!!!!!!!!!!

n200080 [17]

<h3>Answer: Choice C) -3m^12n^6</h3>

Explanation:

The coefficients -24 and 8 divide to -24/8 = -3. Based on this alone, the answer is between choices B and C.

The m terms divide to $\frac{m^5}{m^{-7}} = m^{5-(-7)} = m^{5+7} = m^{12}$

Notice how I subtracted the exponents. The general rule is $\frac{a^b}{a^{c}} = a^{b-c}$

Since we get m^12, this points us to choice C as the final answer

For the sake of completeness, here's what the n terms divide to

$\frac{n^4}{n^{-2}} = n^{4-(-2)} = n^{4+2} = n^{6}$

If it take 10minutes to walk 1/2 of an mile how long will it take to walk how long will it take to walk 1 1/2 of an mile

Fantom [35]

Answer:

About 30 min.

Step-by-step explanation:

Since it takes 10 min to walk a half of mile, it will take 20 min to walk a whole mile.

Since we will be walking one and a half miles, it should take about 30 minutes.

Hope this helps.

In the given right triangle, write all trigonometric ratios ?

Serga [27]

Answer:

see below

Step-by-step explanation:

You will need the hypotenuse 12 ^2 + 9^2 = h^2 h = 15

In a right triangle:

S O H C A H T O A

sin s = S A H = Opposite / Hypotenuse = 12/15

cos r = C A H = Adjacent / Hypotenuse = 12/ 15

Tan s = T O A = 12 / 9

cos (theta) = cos s = 9 / 15

Tan r = 9/12

arc cos(theta) = theta = arccos(9/15) = 53.13 degrees
