The answer is: 90 you can calculate this: 900/10=90
you do the opposite:
520/8=70
70*12=840.
she is thinking of the number 840

Answer:
6.5×10'3=6,500.
5.5×10'5=550,000
1.1×10'3=1,100
so as u can see the second number is greater
by 548,900
Answer:
The perimeter of EFGH is 30.5
Step-by-step explanation:
figure ABCD is similar to figure EFGH (hence the ~ sign)
A -> B= <u>12</u>
B -> C= <u>12 </u>
C -> D= <u>12</u>
A -> D= <u>25</u>
EFGH has sides that are half of the size of ABCD
there are two ways you can solve this:
A) divide the perimeter of ABCD by 2 (making it half)
61 / 2 = 30.5
or
B) adding all of the sides together
E -> F =6 so therefore so do F-> G and G -> H
6 + 6 + 6 + 12.5 = 30.5
