Answer: 120 lb of potatoes.
Step-by-step explanation:
Let the pounds of potatoes sold by farmer Bill = X lb
Fractional part sold to the first person = 1/4
Therefore 1/4 of X = 1/4 x X
= X/4 lb of potatoes.
No of potatoes left for sale = X - X/4
= ( 4x - x )/4
= 3x/4 lb.
Fractional part sold to the second person out of the reminder = 4/9
Therefore 4/9 of 3x/4 = 4/9 x 3x/4
= x/3 lb of potatoes.
Amount of potatoes left for sale = 3x/4 - x/3
Resolve into fraction , we have = (9x - 4x)/12, because 12 is the LCM.
= 5x/12
Third buyer bought 4/5 of the left over = 4/5 of 5x/12
= x/3 lb of potatoes.
Amount of potatoes left = 5x/12 - x/3
Resolve in to fraction again taking 12 as the LCM = ( 5x - 4x )/12
= x/12 lb of potatoes .
Therefore, the left over was 10 lb .
To determine the value of x now which correspond to the amount of potatoes sold by Farmer Bill, we shall the equate the left to x/12 = 10
we now cross multiply to get the value of x x = 120 lb.
therefore the pound of potatoes sold by farmer Bill = 120 lb.
Answer:
120 potatoes
Step-by-step explanation:
Answer:
x = ± 2.45
Step-by-step explanation:
Given
8x² - 48 = 0 ( add 48 to both sides )
8x² = 48 ( divide both sides by 8 )
x² = 6 ( take the square root of both sides )
x = ± = ± 2.45 ( nearest hundredth )
Answer:
Option B and C are correct.
Step-by-step explanation:
Find the expanded form of 840.02.
Any decimal number can be expanded in the form of power of 10.
then;
In 840.02
the first 8 is
8 hundreds i.e, 800 ,
4 is 4 tens i.,e 40 ,
0 ones ,
0 one-tenths and
2 hundredths,
we can write this as;
or
or
Answer:
8 × 100 + 4 × 10 + 2 × 1/100
8 × 100 + 4 × 10 + 0 × 1 + 0 × 1/10 + 2 × 1/100
Step-by-step explanation:
8 × 100 + 4 × 10 + 2 × 1/10 =800+40+2/10 = 840+2/10 = 840.2
8 × 100 + 4 × 10 + 2 × 1/100 = 800+40+2/100 = 840+2/100 = 840.02
8 × 100 + 4 × 10 + 0 × 1 + 0 × 1/10 + 2 × 1/100 =800+40+2/100= 840.02
8 × 100 + 4 × 10 + 4 × 0 + 0 × 11 + 2 × 1/10=800+40+2/10= 840+2/10 = 840.2
