- 1 , 0 , 1
the answer is C
Answer:
(a). 2.251 cm
, 2.349 cm, 2.295 cm
(b). 0.023 meters.
Step-by-step explanation:
(a). We are asked to to choose the options that shows the actual measurement of the rainfall.
Since the rounded figure is 2.3 cm, this means that either the tenths digit is 3 with hundredths digit less than 5, or tenths digit is 2 with hundredths digit greater than or equal to 5.
Let us check our given choices one by one.
![2.251\text{ cm}\approx 2.3\text{ cm}](https://tex.z-dn.net/?f=2.251%5Ctext%7B%20cm%7D%5Capprox%202.3%5Ctext%7B%20cm%7D)
![2.349\text{ cm}\approx 2.3\text{ cm}](https://tex.z-dn.net/?f=2.349%5Ctext%7B%20cm%7D%5Capprox%202.3%5Ctext%7B%20cm%7D)
![2.352\text{ cm}\approx 2.4\text{ cm}](https://tex.z-dn.net/?f=2.352%5Ctext%7B%20cm%7D%5Capprox%202.4%5Ctext%7B%20cm%7D)
![2.295\text{ cm}\approx 2.3\text{ cm}](https://tex.z-dn.net/?f=2.295%5Ctext%7B%20cm%7D%5Capprox%202.3%5Ctext%7B%20cm%7D)
Therefore, the correct choices are 2.251 cm
, 2.349 cm and 2.295 cm.
(b) We know that 1 cm equals 0.01 meters.
To convert 2.3 cm to meters, we will multiply 2.3 by 0.01.
![2.3\text{ cm}=2.3\text{ cm}\times \frac{0.01\text{ meters}}{\text{cm}}](https://tex.z-dn.net/?f=2.3%5Ctext%7B%20cm%7D%3D2.3%5Ctext%7B%20cm%7D%5Ctimes%20%5Cfrac%7B0.01%5Ctext%7B%20meters%7D%7D%7B%5Ctext%7Bcm%7D%7D)
![2.3\text{ cm}=0.023\text{ meters}](https://tex.z-dn.net/?f=2.3%5Ctext%7B%20cm%7D%3D0.023%5Ctext%7B%20meters%7D)
Therefore, the rounded measurement of rain would be 0.023 meters.
Step-by-step explanation:
4 + 7 x X = 22
4+7x=22
7x=22-4
7x=18
x=18/7
Answer:
yes
Step-by-step explanation:
10 is half of 20 but the equation is 11/20 therefore 11/20 is greater than 10/20=1/2
