Answer: 300
Step-by-step explanation:
Let the total number of people surveyed be represented by x.
Since we are informed that the probability of a customer ordering chicken is 1/4 and 75 people said they prefer to order chicken. This will then be:
1/4 of x = 75
1/4 × x = 75
x = 75 × 4
= 300
Therefore, 300 people were surveyed
You should just be able to divide 21/3 and you would get 7 so she would have 7 flowers.
Answer: ![312.5\ cm^2](https://tex.z-dn.net/?f=312.5%5C%20cm%5E2)
Step-by-step explanation:
Given
A and B are two similar shape with lengths of 12 cm and 15 cm
A has an area of ![200\ cm^2](https://tex.z-dn.net/?f=200%5C%20cm%5E2)
For similar figures, ratio of the square of corresponding length is equal to the ratio of the area
![\Rightarrow \dfrac{200}{A_b}=\dfrac{12^2}{15^2}\\\\\Rightarrow A_b=\dfrac{15^2}{12^2}\times 200\\\\\Rightarrow A_b=312.5\ cm^2](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cdfrac%7B200%7D%7BA_b%7D%3D%5Cdfrac%7B12%5E2%7D%7B15%5E2%7D%5C%5C%5C%5C%5CRightarrow%20A_b%3D%5Cdfrac%7B15%5E2%7D%7B12%5E2%7D%5Ctimes%20200%5C%5C%5C%5C%5CRightarrow%20A_b%3D312.5%5C%20cm%5E2)
