Answer:
x = 4.6439
Step-by-step explanation:
2^x =25
Take the log of each side
log 2^x = log 25
We know that log a^b = b log a
x log 2 = log 25
Divide each side by log 2
x = log 25 / log 2
x =4.643856
Rounding to 4 decimal places
x = 4.6439
Answer:
35%
Step-by-step explanation:
Percent increase is (new number - old number) / old number
(162 - 120) / 120 = 42 / 120 = 0.35 = 35%
Answer: 
is needed for 5 servings.
Step-by-step explanation:
Since we have given that
Hemal wanted to make desert for her family for which they made the recipe,
For 8 servings , the number of cups of flour is needed = 2
We will use "Unitary Method" ,
For 1 serving, the number of cups of flour is needed is given by
For 5 servings, the number of cups of flour is needed is given by
Hence, is needed for 5 servings.
Total number of marbles = 5 + 8 + 7 = 20
Total number of non-red marbles = 5 + 7 = 12
P(not red) = 12/20 = 3/5

Answer: 3/5
Answer:
15 ounces of red beans
Step-by-step explanation:
So, we know Kim's soup contains a total of 75 ounces of beans, including red beans (r) and black beans (b), so r + b = 75
Then we know that for each ounce of red beans, there are 4 ounces of black beans, 1b = 4r
Then we merge both equations by replacing b's value in the first equation by its equivalent (b = 4r), since we are looking for the count of red beans.
r + b = 75
r + 4r = 75
5 r = 75
r = 15
There are 15 ounces of red beans in Kim's soup, that looks a lot like the last chili I made :-)
