Answer:
975 girls
Step-by-step explanation:
To find 65% of 1500, multiply 1500 by .65 (to convert percentages to decimals, just move a decimal point over two spaces).
1500*.65=975
You can check that this answer is right with logic. Most of the students will be girls (more than 50%) and 975 makes up most of 1500.

Step-by-step explanation:
the surface area consists of 6 individual areas :
front and back (both are equal)
left and right (both are equal)
top and bottom
front and back are trapezoids.
the area of a trapezoid is
(base 1 + base 2)/2 × h
the bases are the 2 parallel sides.
in our case the area of one trapezoid is
(5 + 19)/2 × 12.1 = 145.2 ft²
front and back together then are 290.4 ft².
left and right are 8×14 rectangles:
8×14 = 112 ft²
together they are 224 ft².
the bottom is a 5×8 rectangle :
5×8 = 40 ft²
the top is a 19×8 rectangle :
19×8 = 152 ft²
so, the total surface area is
290.4 + 224 + 40 + 152 = 706.4 ft²
Answer:
0
Step-by-step explanation:
5(2x + 2) = 10
10x + 10 = 10
10x = 0
x = 0
Answer:
Salary of President = $180,000
Salary of Dept. Head = $60,000
Step-by-step explanation:
The question is to find the salary of president and department head.
We let the salary of one of department heads be "x"
Since, the salary of president is THREE (3) TIMES a department head, we can say:
Salary of President = 3x
Now, we know the total of these 2 salaries is 240,000. Thus, we can write:
Salary of President + Salary of Dept. Head = 240,000
3x + x = 240,000
Now, we can solve for x:
And now the president is "3x", so his salary is:
3(60,000) = 180,000
Thus,
President's salary = 180,000
Dept head's salary = 60,000
