Answer:
<u>27</u> students are girls.
Step-by-step explanation:
Given:
There are 3/4 as many girls as there are boys.
In the fifth grade total there are 63 students.
Now, to find the number of students that are girls.
Let the number of students that are boys be 
So, the number of students that are girls = 
Total number of students = 63.
Now, to get the number of students that are girls we solve an equation:
Now, substituting the value of 
:
Therefore, 27 students are girls.
Answer:
surface are: 300 cm2
volume: 450cm3
Step-by-step explanation:
Hi, to answer this question we have to apply the next formulas:
Surface area of a box = 2wl + 2hw + 2 lh
Where w is the width of the box, l is the length of the box, and h is the height of the box.
The top sides and bottom have only length and width, since there is no top side, the surface area is equal to the outer 5 surfaces.
S = wl + 2hw + 2 lh
Replacing with the values given:
S = (15x10)+ 2(3x10)+ 2(15x3)
S = 150+60+90=300 cm2
For the volume we simply apply:
Volume of a rectangular prism: length x width x height
V = 15x10x3 = 450cm3

Answer:
3.1 kilometers
Step-by-step explanation:
Mark me as brainliest if this helps!
If 5/8 of the teachers are males, there are 45 male teachers.
Subtract this value from 72 (i.e., find 3/8 of 72), and you will find that there are 27 female teachers.
