Answer:
$17.85
Step-by-step explanation:
Let the dollar amount per shirt be represented by s.
Let the dollar amount per pants be represented by p.
You have the following system:
3s+2p=104.81
2s+1p=61.33
If I multiply the bottom equation by -2, I can set the system up for elimination since the equations are already and the same form and I will have 2p and -2p in the same column there. 2p+(-2p)=0
Multiplying equation 2 by -2:
3s+2p=104.81
-4s-2p=-122.66
-----------------------Add the equations:
-1s =-17.85
Multiply both sides by -1:
s=17.85
So one shirt cost $17.85
Answer:
$30
Step-by-step explanation:
Harry starts out with $62.
The 2 jerseys cost 2($4) = $8.
The ball cost $19.
The shorts cost $5.
The amount Harry has left is:
$62 - ($8 + $19 + $5) = $62 - ($32) = $30
The surface area and volume of the real brick will be 983.2 cm²and 1738.11 cm³ respectively.
<h3>What is volume?</h3>
The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic cm.
The scale factor is ;
r = 630 cm /23
r = 27
L = 23 cm
b = 310 / 27 = 11.48 cm
h = 180/27 = 6.6 cm
The surface area of the brick;
A = 2(lb+bh+hl)
A = 2( 23 ×11.48+11.48×6.6+6.6×23)
A= 983.2 cm²
The volume of the brick is;
V= lbh
V=23 × 11.45 ×6.6
V=1738.11 cm³
Hence the surface area and volume of the real brick will be 983.2 cm² and 1738.11 cm³ respectively.
