Answer:
x=10
Step-by-step explanation:
Use the Pythagorean Theorem, which is a^2+b^2=c^2
The formula would lead to:
6^2+8^2=x^2
36+64=x^2
100=x^2
10=x
280 = 7 x 2^3 x 5
882 = 7^2 x 2 x 3^2
For 280k to be perfect square , their powers need to be even
For 882 to be a cube, their powers need to be in multiple of 3,
To satisfy both parties,
K = 7 x 2^5 x 3^4 x 5^3 = 2268000
Ok remember
1st decimal place=tenths=x/10
2nd=hundreths=x/100
3rd=thoustands=x/1000
each place adds a zero
0.5
5 is in tenths place so 5 tenths aka 5/10=1/2
0.66 goes to hundreths so 66/100=33/50
0.7 is also in tenths so 7/10
Answer:if there are 7 HS students for every 2 MS students and there are 18 MS students...
18/2 = 9
9(7) = 63
So, there are 18 + 63 = 81 total students.
Since we had 9 parts last year also (1:8), 81/9 = 9 students are in each part. 8 students in each part are HS and one is MS.
8(9) = 72 HS students last year.
72 - 63 = 9 fewer HS students than last year.
Hope this helps!
