14 because half of 14 is 7 and 10 more than 7 is 17 so 14 is the original number

Find S11 for 1 + 2 + 4 + 8 +

Free_Kalibri [48]

Evaluating the given sequence, it is evident that the next number is twice the number prior to it. Thus, the given is a geometric sequence with first term (a1) equal to 1 and common ratio of 2. The geometric series may be calculated by the equation,

Sn = a1 x (1 - r^n) / (1 - r)

where Sn is the sum of n terms in this case, n = 11.
Substituting the known values,

<span> Sn = 1 x (1 - 2^11) / (1 - 2) = 2047
</span>
Thus, S11 is 2047.

Which set of equations is enough information to prove that lines a and b are parallel lines cut by transversal f? m∠4 = 110° and

atroni [7]

see the attached figure to better understand the problem

we know that

If a and b are parallel lines

then

m∠1=m∠4 --------> by alternate exterior angles

m∠3+m∠4= $180\°$ --------> by supplementary angles

so

m∠3+m∠1= $180\°$

therefore

<u>the answer is the option</u>

m∠1 = 110° and m∠3 = 70°

Answer:

Answer in terms of π=144π m^3

Answer by replacing π with 3.14 is 452.16 approximately 452.2m^3

Answer to the nearest whole no. is 452m^3

Step-by-step explanation:

$volume \: of \: a \: cone = \frac{1}{3} \pi {r}^{2} h$

$radius = \frac{diametre}{2}$

$radius = 24$

$height = 18$

$slant \: height \: = 30$

$first \: step$

$the \: exact \: volume \: of \: the \: cone \: in \: terms \: of \: \pi$

$v = \frac{1}{3} \pi {r}^{2} h$

$\: \: = \frac{1}{3} \times \pi \times 24 \times 18$

$\: \: \: = \frac{432\pi}{3}$

$\: \: \: = 144\pi$

$second \: step$

$approximate \: answer \: using \: 3.14 \: in \: place \: of \: \pi$

$144 \times 3.14$

$= 452.16$

$approximately \: 452.2$

$last \: step$

$answer \: to \: the \: nearest \: whole \: number$

$452 {m}^{3}$

If Mrs.Miller deposits $10,000 into a savings account for 5 years at 5% interest rate ,What is the total amount of money she wil

Alchen [17]

I = C₀*i*t

I = 10.000*0,05*5

I = 2.500

C = C₀ + I

C = 10.000 + 2.500

C = 12.500
