Answer:
Answer:
21378.6
Step-by-step explanation:
You move the decimal point four places towards the right.
Answer:
okay so I believe the answer is 30
step-by-step explanation:
So the area is length times width and a parallelogram is Bh so all you would have to do is multiply 10 by 30
Answer:
5) 975 girls 6) $1440 7) $1000 8) 472
Step-by-step explanation: For 5, cross multiply and to get 975 girls. Do the same for 6. For 7, it says that the television is $550, and it is only 55% of her savings. Therefore, to find her original amount, you will put 550 in the numerator and x in the denominator, and cross multiply 55/100 to get 1000. For 8, do the same thing, and put 354 for the numerator, x for denominator, 75/100 and cross multiply.
Let the number of 4th and 5th graders be x.
The number of k-3 graders will be (x+300)
The fraction of 4th and 5th graders is 5/12
The fraction of the whole students combined is 1/1
The fraction of k-3 graders is 1-5/12=7/12
The total number of students will be x+(x+300)=2x+300
the fraction of 4th and 5th graders will be given by:
x/(2x+300)=5/12
12x=5(2x+300)
12x=10x+1500
2x=1500
x=1500/2=750
Thus the total number of students will be:
2x+300
=2*750+300
=1500+300
=1800
b] Given that of the 4th and 5th graders, (x=750), 2/5 are 4th graders, therefore the fraction of 5th graders will be:
1-2/5=3/5
the total number of 5th graders will be:
3/5*750
=450
The number of 5th graders will be 450
