Answer:

72°

Step-by-step explanation:

There are 5 blades, equally spaced.  So the angle between adjacent blades is 360° / 5 = 72°.  So you can rotate the fan 72° and the blades will align again.

shtirl [24]

Answer:

Step-by-step explanation:

Using I = PRT/100

where P = The principal amount invested = $5500

R = Rate of Interest =5%

T = Time (in years)

I = Interest = $7,739.05 - $5500 = $2239.05

Substituting the above values in the formula

I = PRT/100 becomes

2239.05 = 7,739.05 * 5 * t / 100 -------- Multiply 100 to both sides

2239.05 * 100 = 100 * 7739.05 * 5 * t / 100

223905 = 7739.05 * 5 * t

223905 = 38695.25t

Divide both sides by 38695.25t

223905/38695.25 = t

5.786369 = t

T = 5.79 (approximated)

A cylinder has a height of 2.8 feet and a radius of 5.1 feet. What is its volume? Use 3.14 and round your answer to the nearest
kifflom [539]
<h3>Answer:  228.68</h3>

Work Shown:

V = \pi*r^2*h\\\\V \approx 3.14*(5.1)^2*2.8\\\\V \approx 228.67992\\\\V \approx 228.68\\\\

The volume is approximately 228.68 cubic feet.

The result is approximate because pi = 3.14 is approximate.

Alecsey [184]

Answer:

Step-by-step explanation:

Let's consider an exponential function as,

f(x) = 2ˣ

Now we prepare the input-output value table to get the ordered pairs to be plotted.

f(x)     0.25     0.5          1             2            4           8

x         -2         -1            0            1             2           3    

By plotting these points we get the graph as attached.

Therefore, second option in the last attachment will be the correct option.
