Your answer would be D) -3°F/hour
Look at it this way...

47°F at 7:20pm
46°F at 7:40pm
45°F at 8:00pm
44°F at 8:20pm
43°F at 8:40pm

The temperature is going down by 1°F every 20 minutes so...

-1°F/20 minutes

Obviously there's no answer choice that says that so you'd need to change the minutes into an hour...

So an hour is 60 minutes and 60/20 = 3

So if you do 3・-1

You get the answer... -3°F/hour

rodikova [14]

9514 1404 393

Answer:

  10.3

Step-by-step explanation:

Assuming the blocks are square, we can use the Pythagorean theorem to find the diagonal distance.

 d² = 9² +5² = 81 +25 = 106

 d = √106 ≈ 10.3

Jennifer is about 10.3 blocks from home.

All the edges of a cube have the same length. Tony claims that the formula SA = 6s, where s is the length of
Darina [25.2K]

Answer:

Here's what I get  

Step-by-step explanation:

a. Net of a cube

Fig. 1 is the net of a cube  

b. Does the formula work?

Tony's formula works if you ignore dimensions.

There are six squares in the net of a cube.

If each side has a unit length s, the total area of the cube is 6s.

c. Will the formula work for any rectangular prism?

No, because a rectangular prism has sides of three different lengths — l, w, and h — as in Fig. 2.

d. Area of a rectangular prism

A rectangular prism has six faces.

A top (T) and a bottom (b) — A = 2×l×w

A left (L) and a right (R)    —   A = 2×l×h

A front (F) and a back (B) —   A = 2×w×h

                                  Total area = 2lw + 2lh + 2wh

If l = 5 m, w = 6 m and h = 8 m,

\begin{array}{rl}A &=& \text{2$\times$ 5 m $\times$ 6 m + 2$\times$ 5 m $\times$ 8 m + 2 $\times$ 6 m $\times$ 8 m}\\&=& \text{60 m}^{2} + \text{80 m}^{2} + \text{96 m}^{2}\\&=& \textbf{236 m}^{2}\\\end{array}

TEA [102]
<span>Expected value is the sum of the probability of each even times the outcome of the event.

So she wins $10 with probability 2/8, $3 with probability 1/8, $0 with probability 3/8, and loses $3 with probability 2/8.

So,

E = 10(2/8) + 3(1/8) + 0(3/8) - 3(2/8)
=5/4 + 3/8 - 3/4
=7/4
