Answer:
pre-image rectangle has a length of 4 and width of 3. An image rectangle has a length of 2 and width of 1.5.
She could compare the ratios of the sides of the pre-image to the corresponding sides of the image in the proportion StartFraction 3 Over 1.5 EndFraction = StartFraction 4 Over 2 EndFraction.
Step-by-step explanation:
Unknown side = square root (100 - 49)
unknown side = square root (51)
unknown side = 7.14
Answer:
121.7
Step-by-step explanation:
Use the .746 to round to the nearest decimal place.
To do this you look to the value of the number next to the .7
If it is 5 or higher you round upwards
If it is 4 or lower you round downwards or leave as is.
Therefore .746 rounds to .7
Your answer is 121.7
2x+(-1.5x-2)=4
2x-1.5x-2=4
0.5x-2=4
0.5x=4+2
0.5x=6
x=6×2
x=12
y= -1.5(12)-2
y= -18-2
y= -20
The number of liver cells it would take to form an end to end chain 10 in long is 12,700 liver cells
<h3>Calculating quantity</h3>
From the question, we are to determine how many liver cells it would take to form an end to end chain 10 in long
First, we will convert 10 in to meters
1 inch = 0.0254
∴ 10 inches = 0.254 m
From the giving information,
A liver cell is about 20 μm in diameter
∴ The number of liver cells it would take to form an end to end chain 10 in long = 0.254 m / 20 μm
= 0.254 m / (20 ×10⁻⁶) m (NOTE: 1μm = 10⁻⁶m)
= 12700
Hence, the number of liver cells it would take to form an end to end chain 10 in long is 12,700 liver cells
