Answer:
To the nearest hundredth, the rate of flow will be 75.38 mm/hr
Step-by-step explanation:
Here in this case, we are to express the rate at which the water flow and round it up to the nearest hundredth.
We are told that water flows through the pipe at a rate of 490 mm every 6.5 hours.
Now, the rate will be 490/6.5 = 75.384615384615 mm/hr
Rounding this value to the nearest hundredth, we have 75.38 mm/hr
Answer:
60,000 people
Step-by-step explanation:
Given the number of people y (in thousands) who bought a cell phone without a camera can be estimated by the equation y=-30x+240,
x is the number of years after 2014
<u>We can find the number of people that bought the cell phone in 2020. </u><u>In year 2020, that will be after 6years</u>
Substitute x = 6 into the expression
y=-30x+240
y=-30(6)+240,=
y = -180 + 240
y = 60
Since y is in thousands, hence the the number of people that have bought the cell phone by 2020 is 60,000 people
678 + 303 = 981
Here are a few examples to get you started:
600 + 300 = 900
<span>78 + 3 = 81 </span>
<span>900 + 81 = 981
</span>Here's another one:
678 = 600 + 70 + 8
<span>303 = 300 + 00 + 3 </span>
<span>Add the ones place = 11 </span>
<span>Add the tens place = 70 </span>
<span>Add the hundreds place = 900 </span>
<span>Now add 900 + 70 + 11 = 981</span>
Hope this helps! :-)
