Answer:
12) 3/5=534 students
13)<em> </em>2151 kg
14)a)7.1 US$
b)total=10.2 US$
Step-by-step explanation:
12)students who had lunch=2/5*890
=356 students
students who did not have lunch=5/5-2/5
=3/5*890
<em> =534 students</em>
14)a)4pens=180 cents
2 books=5.3$
<em> total=7.1 US$</em>
<em> </em>b)5 pens=225 cnets
3 books=7.95 US$
<em>total=10.2 US$</em>
10)ate=1 over 8
remaining=8/8-1/8
=7/8
after six hours=7/8*2/5
=7 over 20
total ate=1/8+7/20
=14+5 over 40
=19 over 40
remaining=40 over 40 - 19 over 40
= 21 over 40
to dog=21/40 *1/4
=21 over 160
total=19 over 40 +21 over 160
=152+21 over 160
=173 over 160

Answer:
2√(225 -x²)
Step-by-step explanation:
Let 2y be the length of the second diagonal. The half-diagonals and the side of the rhombus form a right triangle. The Pythagorean theorem tells us the relationship between sides and hypotenuse is ...
x² +y² = 15²
y² = 225 -x²
2y = 2√(225 -x²2) . . . . the length of the second diagonal

Answer:
The length of the piggy bank is 6 cubic inches long, and the height of the piggy bank is 8 cubic inches high. So next, you multiply 6 and 8 together, which is 48. Therefore, the volume of the piggy bank is 48 cubic inches^3.
Step-by-step explanation:
Let the unknown number be x then given,
(4/5)x - (3/4)x = 4
