Answer:
the general formula for the total surface area of a regular pyramid isbT. S. A. =12pl+B where p represents the perimeter of the base
So, she buys 16 bags, each of them weights

pounds.
to find how many pounds of soil she bought, we have to multiply:
16*

=//16 is equal to 8*2, so we can simpify:
2*

which is 2*5=10
so in the end she bought 10 pounds of soil!
V = ( 9*2 ) / 3 ;
v = 18 / 3 ;
v = 6 ;
a. is the right answer;
( 119.5 / 151 ) * 100 = 11950 / 151 = 79.1 ;
The percent is 79.1%;
c. is the right answer;
1 - (40/100)*1 = 1 - 2 / 5 = 3 / 5 = 0.60 ;
d. is the right answer.
Answer:
C
Step-by-step explanation:
I am guessing that's it.
In order to solve, set up a proportion: 22/126=x/100. Cross multiply: 2200=126x. Divide by 126 on both sides: 17.46%=x
