Carl is boarding a plane. He has 2 checked bags of equal weight and a backpack that weight 4kg. The total weight of Carl’s bagga
garik1379 [7]

35 = 4 + 2b

2b = 35 - 4

b = backpack

35 - 4 = 31

2b = 31

Divide by 2

15.5 = b

Each bag weighs 15.5kg.

15.5 * 2 + 4 = 35

31 + 4 = 35

35 = 35

h = kt

k = h/t

350 = k5

350/5 = k

k = 70

Step-by-step explanation:

Given that :

Ballon height varies directly as the Ascent time in minutes

Height of hot air Ballon rises 350 feets in 5 seconds

Expressing as a direct variation :

Let height of Ballon = h

Time it takes to rise = t

h α t

h = kt

k = h/t

350 = k5

350/5 = k

k = 70

Solve for x in each exponential equation. Round off answers to four decimal places.​
ser-zykov [4K]

Answer:

0.6875

Step-by-step explanation:

24.5 = 3.2⁴ˣ

To get the exponent out of its exponent form, we need to take the ln of both sides:

ln(24.5) = 4x · ln(3.2)                              - divide both sides by ln(3.2)

\frac{ln(24.5)}{ln(3.2)} = 4x                                              - divide both sides by 4

x = 0.6875

svp [43]

Answer:

The value of the car will be 6100 dollars in 8.8 years

Step-by-step explanation:

Present value of car = $23900

The value of the car depreciates at 14.25% per year

Let x be no. of years in which  the value of the car becomes 6100 dollars

Formula: N(t)=N_0(1-r)^t

Substitute the values :

6100=23900(1-\frac{14.25}{100})^x\\\frac{6100}{23900}=(1-\frac{14.25}{100})^x\\x=8.8

Hence the value of the car will be 6100 dollars in 8.8 years
