Answer:
6ft by 8ft
Step-by-step explanation:
1/4 inch = 1 ft
1 1/2 inches has six 1/4 inches
6 times 1 = 6ft
2 inches has eight 1/4 inches
8 times 1 - 8 ft
so its 6ft by 8ft

Define their percentage:
----------------------------------
Adam = 100%
Tapiwa = 100 + 5 = 105%
----------------------------------
Find their total percentage:
----------------------------------
100 + 105 = 205
----------------------------------
Find 1%
----------------------------------
205% = 697 liters
1% = 3.4 liters
----------------------------------
Find 100% (Adam):
----------------------------------
100% = 3.4 x 100
100% = 340 liters
----------------------------------
Find 105% (Tapiwa):
----------------------------------
105% = 3.4 x 105
105% = 357 liters
--------------------------------------------------------------------
Answer: Tapiwa = 357 liters and Adam = 340 liters.

Answer:
a) ⅓ units²
b) 4/15 pi units³
c) 2/3 pi units³
Step-by-step explanation:
4y = x²
2y = x
4y = (2y)²
4y = 4y²
4y² - 4y = 0
y(y-1) = 0
y = 0, 1
x = 0, 2
Area
Integrate: x²/4 - x/2
From 0 to 2
(x³/12 - x²/4)
(8/12 - 4/4) - 0
= -⅓
Area = ⅓
Volume:
Squares and then integrate
Integrate: [x²/4]² - [x/2]²
Integrate: x⁴/16 - x²/4
x⁵/80 - x³/12
Limits 0 to 2
(2⁵/80 - 2³/12) - 0
-4/15
Volume = 4/15 pi
About the x-axis
x² = 4y
x² = 4y²
Integrate the difference
Integrate: 4y² - 4y
4y³/3 - 2y²
Limits 0 to 1
(4/3 - 2) - 0
-2/3
Volume = ⅔ pi
Answer:24
Step-by-step explanation:3x9=27
3+3=6
9+9=18
18+6=24
Write the conjugates of them then FOIL both the top and bottom, then factor
