Answer:
154 girls.
Step-by-step explanation:
If ratio of girls to boys is 3 : 4 then 3 / (3+4) = 3/7 of the total is girls.
Number of girls = 3/7 * 360
= 154.
When a negative number is divided by another negative number, <span>sign of the quotient would be positive and always positive</span>
SOLUTION
Given the question, the following are the solution steps to answer the question.
STEP 1: Represent the total number of bricks to be ordered
Let x represent the number of bricks
STEP 2: Interpret the statement
![90\%=\frac{90}{100}=0.9](https://tex.z-dn.net/?f=90%5C%25%3D%5Cfrac%7B90%7D%7B100%7D%3D0.9)
He needs to have 5000 bricks from x bricks, this means that:
![\begin{gathered} 0.9\times x=5000 \\ Divide\text{ both sides by 0.9} \\ \frac{0.9}{x}=\frac{5000}{0.9} \\ x=5555.555555556 \\ x\approx5556\text{ bricks} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%200.9%5Ctimes%20x%3D5000%20%5C%5C%20Divide%5Ctext%7B%20both%20sides%20by%200.9%7D%20%5C%5C%20%5Cfrac%7B0.9%7D%7Bx%7D%3D%5Cfrac%7B5000%7D%7B0.9%7D%20%5C%5C%20x%3D5555.555555556%20%5C%5C%20x%5Capprox5556%5Ctext%7B%20bricks%7D%20%5Cend%7Bgathered%7D)
Hence, he should order 5556 bricks
The answer is B^5 also known as answer choice A
