Hello,
Answer A
\sum _{i=0} ^4 {5^i}=5^0+5^1+5^2+5^3+5^4=1+5+25+125+625

Answer:

A. \sum_{i=0}^{4}5^{i}

Step-by-step explanation:

We are given the series, 1+5+25+125+625.

It is required to find expression representing the given series.

As, we have,

1=5^{0}

5=5^{1}

25=5^{2}

125=5^{3}

625=5^{4}

Thus, it can be seen that the power is ranging from 0 to 4.

Hence, the expression representing the series is, \sum_{i=0}^{4}5^{i}

So, option A is correct.

After a 40% discount the cost of a sofa is $471 what was the original cost of the sofa?
sp2606 [1]

100% - 40% = 60%, meaning the discounted price is really just 60% of the original 100% price, let's say the 100% price is hmmmm "x".

if 60% of the original price is $471, what is the 100% or namely "x"?

\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 471&60\\ x&100 \end{array}\implies \cfrac{471}{x}=\cfrac{60}{100}\implies \cfrac{471}{x}=\cfrac{3}{5}\implies 2355 = 3x \\\\\\ \cfrac{2355}{3}=x\implies 785=x

In order to join a flying club,there is a $200 annual fee and $20 a month fee to maintain the flying club runaway.Write an equat
Fudgin [204]

Answer:

The equation modelling the situation is T=200+20m.

After <u>10 months</u> the cost would be $400.

Step-by-step explanation:

Given:

Annual Fee of flying club = $200

Monthly fee = $20

We need to write an equation for total cost.

Solution:

Let the number of months be denoted 'm'

Let Total cost be denoted by 'T'

Now we can say that:

Total cost is equal to sum of Annual Fee of flying club plus Monthly fee multiplied by number of months.

framing in equation form we get;

T=200+20m

Hence The equation modelling the situation is T=200+20m.

Now given:

We need to find the number of months when total cost will be $400

So we will substitute T= 400 in above equation.

200+20m=400

Subtracting both side by 200 we get;

200+20m-200=400-200\\\\20m=200

Dividing both side by 20 we get;

\frac{20m}{20}=\frac{200}{20}\\\\m=10 \ months

Hence After <u>10 months</u> the cost would be $400.

Manuel bought a balloon (that is a perfect sphere) with a radius of 2 \text{ cm}2 cm2, space, c, m. He wanted his balloon to be
jonny [76]
The original volume of the balloon is given by:
 V1 = (4/3) * (pi) * (r ^ 3)
 Where,
 r: radius of the sphere.
 Substituting values:
 V1 = (4/3) * (pi) * (1 ^ 3)
 V1 = (4/3) * (pi) * (1)
 Then, the volume of the current sphere is:
 V2 = (4/3) * (pi) * ((1 + 2 * (1)) ^ 3)
 V2 = (4/3) * (pi) * ((1 + 2) ^ 3)
 V2 = (4/3) * (pi) * ((3) ^ 3)
 V2 = (4/3) * (pi) * (27)
 The relation of volumes is:
 V2 / V1 = ((4/3) * (pi) * (27)) / ((4/3) * (pi) * (1))
 V2 / V1 = 27/1
 Answer:
 
The ratio of the current volume of the balloon to the original volume of the balloon is:
 
27: 1
