How many square feet are in 100 m squared
Vikentia [17]

Answer:

100 Sq Mt = 1135.69 Sq Ft

Step-by-step explanation:

We are required to find how many square feet are in 100 m squared.

1 meter = 3.37 ft

1 metre x 1 meter = 3.37 x 3.37 Sq ft

1 Sq Mt = 11.3569 Sq ft

100 sq Mt = 100 x 11.3569 sq ft

100 sq mt = 1135.69 Sq ft

Hence

100 Sq Mt = 1135.69 Sq Ft

A rental car company charges $35 a day plus $.15/mi for a mid-size car. A customer owes $117.25 for a three-day rental. How many
Molodets [167]
The base charge is 35 dollars per day. He rented the car for 3 days, so before you add in the mileage you have to multiply 35 x 3 days for 105 dollars. Then you have to take the remaining charge and divide it by the charge per mile to get the number of miles driven.  Lets set up the equation.

d= number of days rented
m= number of miles driven

35(d) + .15(m) = 117.25
35(3) + .15m = 117.25
105 + .15m = 117.25
.15m = 117.25 - 105
.15m = 12.25
m = 12.25/.15
m = 81.67

So he drove 81.67 miles

(4+8+12+16+...+204):(2+4+6+...+102=
Vikki [24]

Both numerator and denominator are a sum of 51 terms, counted skipping 4s (numerator) and 2s (numerator).

So, you have

\dfrac{\displaystyle\sum_{i=1}^{51} 4i}{\displaystyle\sum_{i=1}^{51} 2i}

Use the linearity of sum to rewrite this as

\dfrac{\displaystyle4\sum_{i=1}^{51} i}{\displaystyle2\sum_{i=1}^{51} i}

So, as you can see, the numerator is exactly twice the numerator: you can cancel out the sum and you have

\dfrac{4}{2} = 2
