Step-by-step explanation:
We know that a^b / a^c = a^ (b-c)
12 ^ -8 / 12 ^ -9
12 ^ (-8 - -9)
12 ^ (-8+9)
12 ^ 1
12
Answer:
The Answer is 12. (Someone deleted my answer because I didn't show any work.)
Step-by-step explanation:
1. 12^-8/12^-9 --> 12^-8-(-9)
2. 12^-8+9
3. 12^1= 12
4. Therefore the answer is 12.

John’s car can travel 40 miles on 4 gallons of gas? This cost a total of $30 for the gas. How many gallons of gas would it need to travel 100 miles?
Answer: 10 gallons
Step-by-step explanation: 40 divided by 4 is 10, apply same knowledge
Answer:
10 gallons of gas
Step-by-step explanation:
If John's car can travel 40 miles on 4 gallons of gas, then it can travel 10 miles on 1 gallon of gas.
To travel 100 miles, the car would need 100/10 = 10 gallons of gas.
Since it cost $30 for 4 gallons of gas, 1 gallon of gas would cost $30/4 = $7.50.
Therefore, it would cost 10 x $7.50 = $75 for the car to travel 100 miles.

Dina has a number cube that she uses for a game.
The number cube has the shape of a triangular pyramid, with 4 faces numbered 1 through 4. Dina rolls the number cube 100 times and records the results. She calculates the relative frequency of each outcome.
Outcome 1 2 3 4
Relative Frequency 0.23 0.24 0.26 0.27
Which statements about Dina's experiment are true?
Select each correct answer.
The relative frequencies in the table are reasonably close.
The theoretical probability of rolling an even number is 0.51.
The relative frequency of rolling an even number is 0.51.
The number cube is not likely to be fair.
Answer: the relative frequencies in the table are reasonably close.
Step-by-step explanation:
Theoretically relative frequency for all numbers are 0.25. If cube is cast
100 times there my be small fluctuations.
A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

2 1.05 x 10^7
Step-by-step explanation:
1.75 * 10^4 = 17500
that's 17500 apples per tree
so you multiply 17500 by 600 tree
you get 10500000
the scientific notation is basically removing zeros
so its 1.05 x 10^7

How to express 5 x 5 x 5 using exponent?
(A) 103 (B) 53 (C) 23
Answer:
B
Step-by-step explanation:
An exponent is a number multiplied by itself several times. 5x5x5 is multiplying 5 three times, so it would be 5 to the power of 3.
Hey there!
5 * 5 * 5
= 5^3
= 25 * 5
= 25 + 25 + 25 + 25 + 25
= 50 + 50 + 25
= 100 + 25
= 125
Thus, the equation answer should be:
125
Therefore, the overall answer should be: 5^3
(Because you’re EXPRESSING 5 THREE times)

Find the error(s) and solve the problem correctly.
Sarah was asked to solve the following problem. Identify her errors and explain how to correct her mistakes.
Answer:
\(5x^3-18x^2+2x+21\)
Step-by-step explanation:
In the second step, -9x-21 should be 9x+21. This is because -3 in x-3, and -3x-7 in 5x²-3x-7 are both negative, so each term's product should be positive.
Also, in the third line, she wrote -3x²-15x² as -18x⁴ instead of -18x²,and similarly, she wrote -7x-9x as -16x² (however this is wrong anyway because step 2 was done incorrectly).
If we continued off from the second step with these corrected errors:
\(5x^3-3x^2-7x-15x^2+9x+21\\5x^3-18x^2+2x+21\)
Therefore, the correct simplification is \(5x^3-18x^2+2x+21\).
Answer:
5x^3-18^2 +2x +21

Calculate (6.25 x 10^9) − (3.44 x 10^8). NEED HELP ASAP WILL GIVE BRAINLIST Step by Step needed
5.906 x 10^9
5.906 x 10^8
2.81 x 10^9
2.81 x 10^1
Answer:
5.906 x 10^9
Step-by-step explanation:
(6.25 x 10^9) − (3.44 x 10^8).
step 1: make the exponents have common value
Move decimal point of 3.44 to the left once and add 1 to it's exponents.
that is 3.44 x10^8 becomes 0.344 x 10^9
= 6.25 x 10^9 - 3.44 x 10^8
= 6.25 x 10^9 - 0.344 x 10^9
step 2: bring out the common factor 10^9 since the exponents are the same.
Also, subtract the decimal numbers.
= (6.25 -0.344) 10^9
6.25 - 0.344 = 5.906
Therefore, the result is 5.906 x 10^9.

Clara and her little sister are making kites to fly in the park. Clara ties 60 centimeters of ribbon to the bottom of her little sister's kite. Clara's kite is bigger, so she needs more ribbon than her sister. Clara uses an extra 40 centimeters of ribbon for her own kite. If Clara started with 2 meters of ribbon, how many centimeters does she have left?
Answer:
Clara will have 40 centimeters of ribbon left.
Step-by-step explanation:
1 meter is the same as 100 centimeters, so 2 meters is 200 centimeters. So, we take 200 centimeters, subtract 60 centimeters:
\(200 - 60= 140\)
so she has 140 centimeters, then we subtract another 60 centimeters for Clara's kite:
\(140 - 60= 80\)
But remember, she needs an extra 40 centimeters because her kite is bigger:
\(80 - 40= 40\)
So, Clara is left with 40 centimeters, or 0.4 meters, of ribbon.
