Answer: It decreased by 24F not 10F because if it were 10F the starting temperature had to be -7F since the difference between this number and -17F is 10F but in this case it starts at 7F so we subtract 7-0=7 and 17-0=17 and add 17+7=24F.
Step-by-step explanation:
7-0=7
17-0=17
17+7=24F
Answer:
A = 2.83 feet²
Step-by-step explanation:
From the attached figure,
Length of the cube, l = 1.5 ft
Breadth of thecube, b = 0.5 ft
Height of the cube, h = 4 inches
We need to find the surface area of this figure.
We know that : 1 foot = 12 inch
4 inches = 0.334 foot
It is in the form of a cubiod. The formula for the surface area of a cuboid is given by :
A = 2(lb+bh+hl)
Put all the values in the above formula :
A = 2(1.5×0.5+0.5×0.334 +0.334×1.5)
A = 2.83 feet²
So, the surface area of this figure is 2.83 feet².
Given that,
Marcel has $8.25 and is only playing $0.25 games. Floyd has $9.75 and is only playing $0.75 games.
Jorge wants to find the number of games after which Marcel and Floyd will have the same amount of money remaining.
The attached figure shows the equation that Jorge had :
8.25-0.25x=9.75-0.75x
Subtract 9.75 to both sides
8.25-0.25x-9.75=9.75-0.75x-9.75
-1.5-0.25x=-0.75x
Add 0.25x to the both sides,
-1.5-0.25x+0.25x=-0.75x+0.25x
-1.5=-0.5x
⇒ x = 3
Jorge is incorrect at step 2 where he taken -0.25x to the RHS such that -0.75x+0.25x, he get 0.5x instead of (-0.5x). Hence, From Step 1 to Step 2, Jorge did not add 0.25x correctly to both sides.
