What is index form?Index form is defined as the exponent or power of a number or variable.
Given the index forms;
(5.3 x 108) − (8.2 x 106)
To subtract, the index forms must have the same exponential values
5.3 x 10^8 - 0. 082 × 10^8

How many ounces of 50% alcohol solution must be mixed with 80 ounces of a 20% alcohol solution to make a 40% alcohol solution?
Answers
y = total amount after mixing
Note that the amount of alcohol in the 20% solution is 80 (0.2) = 16 oz.
We have 2 unknowns, so we need 2 equations:
first, we can write the equation for the total volume:
y = x + 80
next, apply the percentages to get an equation for the amount of alcohol:
0.4 y = 0.5 x + 16
Finally, solve the pair of equations (in this case, by substitution of the 1st into the second:
0.4 (x + 80) = 0.5x + 16
0.4 x + 32 = 0.5X + 16
rearrange and combine like terms:
0.1x = 16
x = 160
from the 1st equation:
y = 160 + 80 = 240

What do you mean by Mean?Aside from the mode and median, the mean is one of the measures of central tendency used in statistics. The average of the specified collection of numbers is what is referred to as the mean. It indicates a data set's values are distributed equally. The three most popular methods for determining central tendency are the mean, median, and mode. To find the mean, tally up all the values listed on a datasheet, then divide that total by the total number of values. When all the values are organised in ascending order, the median is the value that falls in the middle of the data. The number in the list that is repeated a maximum number of times is the mode, in contrast.

Which of the following is an irrational number?

√89
Answers
The square root of 89 is an irrational number with never-ending digits
Solution :
Real numbers :
Real numbers are the sets of rational numbers and irrational numbers taken together
Irrational numbers:
Irrational numbers are the set of all numbers that are not rational; they cannot be written as either a terminating or repeating decimal; they cannot be expressed as a fraction of two integers.
or,
The set of irrational numbers is the set of numbers that are not rational, are non repeating, and are non terminating. Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction, p/q where p and q are integers. The denominator q is not equal to zero (q ≠ 0). Also, the decimal expansion of an irrational number is neither terminating nor repeating.
1)65.555
Statement:65.555....is rational and a repeating decimal
2)-57
Statement: It is a negative integer.
3)[tex]\sqrt{89}[/tex]
Statement:
Due to the nature of its non-repeating and non-terminating decimal expansion, the square root of 89 cannot be written in the form of p/q, hence, it is an irrational number.
The value of the square root of 89 in decimal form is 9.433981.. so on, The square root of a number can have two values, a positive and a negative value. So, √89=+9.433981. Hence, The square root of 89 is an irrational number with never-ending digits.
Step 1: Divide the number 89 by 9, (because 92 =81 is a perfect square number just less than 89).
Step 2: The divisor and the quotient need to be the same numbers; in this case, it is 9. Multiply the quotient and the divisor and subtract the result from 89.
Step 3: For the next divisor, add the previous divisor with the quotient. (9 + 9 = 18); place it as the new divisor with a blank on its right.
Step 4: Put a decimal after the quotient '9' and bring down two zeros to place it after 8 so that it becomes 800. (184 × 4 = 736). Subtract 736 from 800.(800 − 736 = 64)
Step 5: Bring down another pair of zeros and place it after 64, so that it becomes 6400. Take the new quotient 4 and add it to 184. (184 + 4 = 188)
Step 6: Repeating the above steps, we need to fill the blank with a number such that when the new divisor is multiplied by the new quotient, the product is less than or equal to the dividend 6400. (1883 × 3 = 5649)
Step 7: Write the same number after 4 in the quotient. Subtract 5649 from 6400. (6400 − 5649 = 751)
Step 8: Repeat the process until we get the remainder equal to zero. The square root of 89 up to two places is obtained as 9.43 by the long division method.
