Answer:

6 x 10^11

Step-by-step explanation:

6 x 10^11 = 60,000,000,000

0.2 x 10^5 = 020000, which doesnt make sense. in scientific notation, to only way for the number after the decimal when the whole number is 0 is if the exponent was negative. the correct answer is a, i took the test and got it right

Please help me with 13 and 15 asap
Law Incorporation [45]
Gosh, I've done this problem before. Let's start with 13. In this problem, we're basically just skip counting. For example, in the roses row, in the second bouquet, we know we have to add 4 more flowers, so we can document 8. Continue to skip count for both. For 15, we would have about 96 more movie posters remaining, making our ratio 96:x. So, 96:x = 120:100. Therefore, x would equal 80- as 96:80 equals 120:100. If she needs 80 and already had 100, she should sell 20 posters. Hope this helped.

Answer:

$15,339

Step-by-step explanation:

C(x) = 0.5x² − 100x + 20,339

Since this is a parabola, the minimum cost is at the vertex:

x = -b / (2a)

x = -(-100) / (2 × 0.5)

x = 100

So the minimum cost is:

C(100) = 0.5(100)² − 100(100) + 20,339

C(100) = 15,339

Who has more 3/8 or 2/3?
aleksley [76]

Answer:


Step-by-step explanation:

Compare, what fraction is larger? 2/3 vs. 3/8. Fractions sorted in ascending order: 3/8 < 2/3. Ordinary math fractions compared, result explained below

 

Comparing fractions operation:  

2/3 vs. 3/8

Reduce (simplify) fractions to their lowest terms equivalents:

2/3 already reduced to lowest terms, numerator and denominator have no common prime factors, their prime factorization:  

2 is a prime number and 3 is a prime number;

3/8 already reduced to lowest terms, numerator and denominator have no common prime factors, their prime factorization:  

3 is a prime number and 8 = 23;

To sort fractions, build up their numerators the same.

Calculate fractions' numerators LCM (lowest common multiple), it will be the common numerator of the compared fractions:

Numerators' prime factorization:

2 is a prime number;

3 is a prime number;

For LCM, take all the unique prime factors, by the largest exponents:  

LCM (2, 3) = 2 * 3 = 6

Calculate each fraction's expanding number (LCM divided by each fraction's numerator):

For fraction: 2/3 is: 6 ÷ 2 = (2 * 3) ÷ 2 = 3;

For fraction: 3/8 is: 6 ÷ 3 = (2 * 3) ÷ 3 = 2;

Expand the fractions, build up each fraction by multiplying its numerator and denominator by its expanding number, so all the numerators are built up to their LCM, the lowest common multiple:

2/3 = (3 * 2)/(3 * 3) = 6/9;

3/8 = (2 * 3)/(2 * 8) = 6/16;

Fractions have equal numerators, simply compare their denominators.

The larger the denominator the smaller the positive fraction.

::: Comparing operation :::  

Final answer:

 

Fractions sorted in ascending order:  

6/16 < 6/9  

Initial fractions in ascending order:  

3/8 < 2/3
