<u>Solving for A when h = 9</u>
Last option is correct
Answer: 16 + 55 = 71cm^2
Step-by-step explanation:
You want to divide this figure into 2 rectangles. There are two ways to do this, but either one will give you the same answer.
First One:
It has the dimensions of 5 and 11. 5 x 11 = 55cm^2
Second One:
This one wont be straightforward like the first one. You need to find these sides manually.
7 + x = 11
x = 4
Then,
9 - x = 5
x = 4
4 x 4 = 16cm^2
Answer: 15
Step-by-step explanation:
Given: The present ratio of students to teachers at a certain school is to . If the student enrollment were to increase by students and the number of teachers were to increase by , the ratio of students to teachers would then be to .
To Find: What is the present number of teachers.
Solution:
let the number of teachers in schools are
As the current ratio of students to teachers is to
Number of students in school are
Now,
If number of student enrollment and teachers were to increase by and respectively.
New number of students in school would be
New number of teacher in school would be
new ratio of students to teachers is
Hence the number of teachers in school is
