An airplane flies at a constant speed. It can travel a distance (d) of 1,800 kilometers in 2 hours (t).
ss7ja [257]
D = 900t

because if you want to simplify t (2 hours) into one then you divide 1800 by 2 and that gives you the constant of proportionality (slope) of 900. Using this information you can write the expression d = 900t.

Macy's is having a one-day 35% off special. If Sara bought $124.50 worth of items, what would the final bill total after applyin
34kurt

The final bill after applying discount will be $80.92

Step-by-step explanation:

Given,

Worth of items bought by Sara = $124.50

Discount = 35%

Amount of discount = 35% of worth of items

Amount of discount = \frac{35}{100}*124.50

Amount of discount = 0.35*124.50

Amount of discount = $43.575 = $43.58

Final bill = Worth of items - Amount of discount

Final bill = 124.50 - 43.58 = $80.92

The final bill after applying discount will be $80.92

Find the sum of all positive integers less than 200, which:
Allushta [10]

Answer:

3900

Step-by-step explanation:

We want the sum from 5 to 195

5, 10, 15, 20,......195

an = 5 + 5(n-1)  since we can write this as an arithmetic sequence, adding 5 each time

The sum of the terms of an arithmetic sequence is given by

Sn = n/2 [2a1 + (n - 1)d],  

where d is the common difference of 5 and n is the term we want to add to

195/5 = 39  so it is the 39th term

s39 =39/2 [2*5 + (39-1)*5)]

s38 = 19.5[10+38*5]

        =19.5*[10+190]

          19.5*200

          =3900

Which expression results when the change of base formula is applied to log Subscript 4 Baseline (x 2)?.
atroni [7]

The expression results when the change of base formula is \rm \dfrac{log(x+2)}{log4}.

We have to determine

Which expression results when the change of base formula is applied to log Subscript 4 Baseline (x + 2)?

<h3>What is logarithmic property?</h3>

The logarithm of a product as a sum of logarithms, the log of the quotient as a difference of log, and log of power as a product.

The base change formula is;

\rm loga_x= \dfrac{log_bx }{log_ba}\\\\

The expression results when the change of base formula is applied to log Subscript 4 Baseline (x + 2) is;

\rm = log_4(x+2)\\\\=\dfrac{log(x+2)}{log4}

Hence, the expression results when the change of base formula is \rm \dfrac{log(x+2)}{log4}.
