Answer:
B) 0.2
Step-by-step explanation:
1/4 as a decimal 0.25
0.25 x 0.8 = 0.2!
c:
Answer:
x=2/3 or x=−1/2
Step-by-step explanation:
6x²−x=2
6x²−x−2=2−2
6x²−x−2=0
(3x−2)(2x+1)=0
3x−2=0 or 2x+1=0
x=2/3 or x=−1/2
2x + 5y = 5
5y = 5 - 2x
y = (5 - 2x)*(1/5)
y = 1 - 2/5x
y= -2/5x + 1
--------
This means that 2x+5y=5 is a line of the form y=mx+C, whereby m=-2/5 and C=1.
When x=0,
5y=5
y=5/5
y=1.
FIRST COORDINATE (0,1)
When y=0,
2x=5
x=5/2
x=2.5
SECOND COORDINATE (2.5, 0)
Draw a line through the coordinates (0,1) and (2.5, 0) and your graph will emerge.
If the length of side of base is 14 inches and height is 6 inches of pyramid a then the volume of pyramid a is 12.5% of pyramid b and volume of pyramid a is 8 times bigger than volume of pyramid b.
Given the length of side of base of pyramid a is 14 inches , height of pyramid a is 6 inches and volume of pyramid b is 3136 cubic inches.
We have to determine the percentage and number of times that volume of b is bigger than volume of pyramid b.
Volume of a square pyramid=base area * height/3
Base area = Side * side
=14*14
=196 inches square.
Volume of pyramid a =196*6/3
=392 cubic inches.
Percentage=Volume of pyramid a / volume of pyramid b*100
=392/3136*100
=12.5%
Let the number of times be x.
So,
392*x=3136
x=3136/392
=8 times.
Hence the volume of pyramid b is 8 times bigger than volume of pyramid a and the percentage is 12.5%.
