Mathematics
1 answer:
alexandr1967 [171]3 years ago
7 0

Given:

\log (5k+4)=8r

To find:

The exponential form of given equation.

Solution:

We have,

\log (5k+4)=8r

According to the property of the logarithm,

\log_ax=y\Rightarrow x=a^y

Using the above property of the logarithm, we get

5k+4=10^{8r}        

Therefore, the required equation in exponential form is 5k+4=10^{8r}.

roger completed a probability experiment with a coin. he flipped the coin 32 times, and it landed on tails eight times. he looke
vladimir2022 [97]
I don't know what this question is asking exactly, but if i am right, it is asking for the ratio of heads flipped to tails flipped. If this is correct, then the ratio would be 24 to 8. My reasoning for this is, it already tells you that you have 8 times that tails was flipped, and all you have to do to figure out the amount of times heads if flipped it to subtract: 32-8=24, so that means that heads was flipped a total of 24 times. The last thing that you have to do is to put it into a ratio, and in the order it gives you initially, which would make the answer (3 ways):

1)   24 to 8
2)   24 : 8
3)   24/8

I hope this helps you.

What is the value of x?<br><br><br><br> Enter your answer in the box.<br><br><br> _____ units
krek1111 [17]

Answer:

x=28

Step-by-step explanation:

We can use similar triangles and proportions to solve this problem.  Put the side of the small triangle over the same side of the larger triangle.

x               42

---------- = ----------

x+10           42+15

Simplify

x               42

---------- = ----------

x+10           57

Using cross products

57x = 42 (x+10)

Distribute

57x = 42x+420

Subtract 42x from each side

57x-42x = 42x-42x +420

15x = 420

Divide each side by 15

15x/15 = 420/15

x=28

An electrician charges $40 to come to your house.She also charges $55for each that she works. The electrician charges you total
shusha [124]

Answer:

Step-by-step explanation:

First, write an equation. 55x+40=190.

X represents the hours the electrician works. The 55 represents the $55 that she charges for each hour she works. The +40 for the $40 that was the price just to come to your house. The 190 is the total cost. Now, solve that equation.

55x+40=190

55x=150

x=2.72727272...

So the answer is 2.727 hours. It can be rounded as needed or turned into a decimal, 2 8/11.
