I know how to help you, but I need the story attached for me to help.
<h2>
1. Find the SA of all of the parts:</h2>
SA of Triangle parts:
We won't be doing 5x6x1/2 because if we want the surface area of 2 areas, then we will just do normal (5x6)
(2 × 8 2) + (3 × 10 2)
SA: B x H
: 5 x 6
: 30
The surface area of the triangular parts is 30cm²
SA of Large Rectangular (in the middle) part:
SA: L x W
: 6 x 16
: 96
The surface area of the rectangular parts is 96cm²
SA of Large Rectangular (top&bottom) part:
SA: L x W x 2
: 16 x 8 x 2
: 256
The surface area of the rectangular parts is 256cm²
<h2>
2. Add all the SA's to get FINAL answer:</h2>
30+96+256=382
<h2>
So hence, The SA of the Triangular prism is: 382cm²</h2>
:D
Answer:
Store 1= $150
Store 2= $250
Step-by-step explanation:
Let the amount invested by store 1 be x while store 2 be y hence
10x-8y=1300 Eqn 1
Make x the subject of the formula for the first equation
10x=1300+8y divide both sides by 10
X=130+0.8y
6x+5y=2250 Eqn 2
Substituting where there’s x with 130+0.8y in equation 2 we obtain
6(130+0.8y)+5y=2250
780+4.8y+5y=2250
9.8y+780=2250
9.28y=2250-780=1470
Y=1470/9.8=150
X=130+0.8y= 130+0.8(150)=250
She has 648 shirts.
Work:
Lisa has 42 pineapples. 4 + 2 = 6
Johnny has 6 marbles.
42 + 4 + 2 + 6 = 54
54 + 5 + 4 = 63
63 + 6 + 3 = 72
But 72 is a multiple of 6!
Let's go further:
72 * 6 = 432
Now let's look at the word 'shirt'.
The middle letter is I.
I is the 9th letter of the alphabet.
Remember the number 72?
72*9 = 648
