Answer:

V=512^2/3* 19683^1/3*256^1/4    = 6912

Step-by-step explanation:

V= (512^{\frac{2}{3} } ) \times (19683^{\frac{1}{3} } )\times  (256^{\frac{1}{4} } )\\

As

2^{9}  = 512\\2^{8} =  256\\19683^{\frac{1}{3} } = 27\\

putting values in equation

V= 2^{9(^{\frac{2}{3} } )} \times 27 \times 2^{8^({\frac{1}{4}) } } \\  let it be equation 1

As

2^9^{\frac{2}{3} }  = 2^6    according\,to\,exponential\,rule\\2^8^\frac{1}{4} =     2^2     according\,to\,exponential\,rule\\\\

putting values in equation 1

V= 2^6\times 27\times 2^2

According to exponential rule 2^6 \times 2^2 = 2^8

V=2^8 \times 27\\

V=256\times 27\\V=6912

So

V= 6912

Prove that a line that divides two sides of a triangle proportionally is parallel to the third side. Be sure to create and name
sattari [20]

Answer:

Given: A triangle ABC and a line DE parallel to BC.

To prove: A line parallel to one side of a triangle divides the other two sides proportionally.

Proof: Consider ΔABC and DE be the line parallel to Bc, then from ΔABC and ΔADE, we have

∠A=∠A (Common)

∠ADE=∠ABC (Corresponding angles)

Thus, by AA similarity, ΔABC is similar to ΔADE, therefore

AB/AD= AC/AE

⇒AD+DB/AD = AE+EC/AE

⇒1+DB/AD = 1+ EC/AE

⇒DB/AD = EC/AE

Therefore, a line parallel to one side of a triangle divides the other two sides proportionally.

⇒Therefore Proved

Twenty-one out of 70 customers at the restaurant ordered dessert. What percentage of the customers did not order dessert?
yan [13]
Hello!

To find your answer you must subtract first:

70 - 21 = 49

Now, how much percent is 49 of 70?

49/70 = 0.7000

0.7000 * 100 = 70.00%

49 is 70% of 70.

I really hope this helped you! :)

To check your answer: (70 × 70.00)/100 = 49

The half life of a radioactive substance is 10 years. If 64 grams are placed in a
geniusboy [140]

Answer:

2 grams

Step-by-step explanation:

50 years is 5 half lives as 1 half life is 10 years.

64 divide 2 = 32-1 half life

32 divide 2 =16-2nd half life

16 divide 2 = 8-3rd half life

8 divide 2 = 4-4th half life

4 divide 2 = 2-5th half life

This means we will have 2 grams left of the radioactive substance after 50 years.

Total power generated by wind worldwide doubles every 3 years. In a particular year, the world wind-generating capacity was abou
gogolik [260]
<span>Total power generated doubles every 3 years, so the growth rate is: (final value / initial value)^(1/years) - 1 = (2 / 1)^(1/3) - 1 = 26% For the formula, the initial capacity was 92 thousand megawatts, so as a function: WW = Initial Capacity*(1 + growth rate)^(tt) WW = 92*(1+26%)^(tt)</span>

If m&lt;1 is the supplement of m&lt;2 and the measure of each angle is given:
svp [43]

Answer:

m<1 = 121°

m<2 = 59°

Step-by-step explanation:

If m<1 is the supplement of m<2 and the measure of each angle is given:

m<1=2x+65

m<2=3x-25

Find m<1:

When two angles are supplement of each other, there sum is equal to 180°

i.e m<1 + m<2 = 180°

Putting values and finding angle 1

2x+65+3x-25=180\\5x+40=180\\5x=180-40\\5x=140\\x=\frac{140}{5}\\x=28

So, we get x=28

Now finding m<1 by putting x=28

m

Now, finding m<2 by putting x=28

m

So, we get:

m<1 = 121°

m<2 = 59°
