Answer:
B. 70
Step-by-step explanation:
<h3><u>look at the smaller triangle</u></h3>
its dimensions are :
45 , 35 , 24
<h3><u>look at the bigger triangle ( this includes the dimensions of the smaller one)</u></h3>
its dimensions are :
45 + 45 , x , 24 + 24
= 90 , x , 48
from the dimensions given we can notice that :
<em>bigger triangle dimensions are = 2 * smaller triangle dimensions</em>
<em></em>
therefore to find the value of x :
x = 35 * 2
<h3><u>x = 70</u></h3>
<u />
<h3><u>hence the answer is B ) 70 </u></h3>
Let x be your first alloy
2/5x+7/10(30-x)=1/2(30)
4x+210-7x=150
3x=60
x=20
So, you need 20 lbs of the first alloy, and 10 parts of the second to make 30 lbs of half iron and half silver alloy!
Answer:
6 8/9 , 69/10 , 6.99 , 7.927
Step-by-step explanation:
Answer:
if you go on calculator soup just input the numbers and what type of triangle it is and it will solve it for you
A.
8*8=64
9*9=81
as you can see it would be between these 2
