Answer: 36 beans
Step-by-step explanation:
Make a proportion
For every 100 beans, 8 are damaged
8/100
For every 450 brand, x are damaged
x/450
Set the expressions equal to each other
8/100=x/450
100x=3600
Divide by 100 on both sides
x=36
So, out of 450 beans, 36 should be damaged
Hope this helped! :)
Answer:
$5.4
Step-by-step explanation:
45% of $12.00 = 45/100 x 12
= $5.4
Hence to get how much he saved, we have to deduct the percentage off from the cost price $12 -$5.4 = $6.6
∴ Jason saves $5.4
Answer:
96cm
Step-by-step explanation:
For a triangular prism we find the surface area by doing base times height/ length times width, but since we have a triangle we would have to divide the answer we get by 2. Once we get all the sides we then would have to add them all up.
<h3>front back top </h3>
3X4X1/2 ( HINT: ITS THE SAME AS THE FRONT) 7X5
12X1/2 6= back 35= top
6= front
<h3>Bottom side <u><em>
since we are done finding all</em></u> </h3>
7X4 3X7 <em><u>of the area of the shapes we add </u></em>
28= bottom 21= side <u><em>all of them together.</em></u>
Surface area= 6+6+35+28+21= <u><em>96 cm</em></u>
