Tania measured the growth of her plant each week. The first week, the plant's height measured 4.78 decimeters. During the second week, Tania's plant grew 0.7 decimeter. How tall was Tania's plant at the end of the second week? Complete the description of the steps to solve the problem.

From rounding each number to the nearest whole number, an estimate of the sum is about ()
decimeters. Then add 4.78 and 0.7. Write an equivalent decimal for 0.7 so the addends have the same number of decimal places. Add the hundredths, then the tenths. Regroup 10 tenths as 1 one, and add the ones. At the end of the second week, Tania's plant was
decimeters tall.

The answer is close to the estimate so the answer is ()

ahem, I'm sorry but the education system sucks, I would straight up tell my teacher that.

just add 4.78 + 0.7 and ta-da! 5.48 is your final answer.

hey, I was only a year late, I'm sure you still need more questions answered, so look me up,

mrmepp will always be there for you during these hard... hard times...your welcome...

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
