Answer:

Answers on edge :)

Step-by-step explanation:

The bases are not the same, so you cannot set 3x - 1 equal to 8.

You can evaluate the logarithm on the right side of the equation to get 3.

You can use the definition of a logarithm to write 3x - 1 = 1000.

This is because logarithm has its own set of properties that is different from algebra. The term log(3x - 1) is equivalent to log 3x/log 1. If we continue to rearrange and find x, the solution would be:

log(3x - 1) = log28
log 3x/log 1 = log 28
log 3x = log 28 * log 1 = 0
3x = 10⁰ = 1
3x = 1
x = 1/3

<em>So, that means 3x - 1 = 3(1/3) - 1 = 0.</em>

horrorfan [7]

Step-by-step explanation:

charging the phone for 1 minute ,it has 2%

i.e,1----->2

After 2 minutes from that time ,i.e total 3 minutes

it has 6% charge

i.e,3--------->6

from the both the above cases ,1 minute provide 2%=6/3

=2

Hence,

for getting 50%charge=50/2

=25 min

and,for 90 %charge=90\2

=45 min

Fatheya purchased a prepaid phone card for $25. Long distance calls cost 12 cents a minute using this card. Fatheya used her car
Pachacha [2.7K]

Answer:

22 minutes

Step-by-step explanation:

First you take away the original amount away from the remaining amount.

$25 - $22.36 = $2.64

Then you take that number and divide it by the cents per minute.

$2.64 ÷ 12 = 0.22

Then that's your answer!

Her call lasted 22 minutes.

10) A wheelchair ramp is getting built at the entrance of a building. The ramp will be 25 feet long from front
mezya [45]

Answer:

The angle complies with the state regulations.

Step-by-step explanation:

The angle of elevation is the angle \theta in the figure, and from trigonometry we find that

sin(\theta) = \dfrac{1.5ft}{25ft}

taking the inverse sine of both sides we get

\theta = sin^{-1}(\dfrac{1.5ft}{25ft})

which gives

\theta = 3.44^o

which is less than 5°, and therefore is well within the state regulations.
