Answer: the expression that represents the total number of items that have been collected is
7d + 12
Step-by-step explanation:
You are collecting pairs of socks and toothbrushes for a local charity.
Total number of pairs of socks that you would have collected after d days is (4d+5)
Total number of toothbrushes that you would have collected after d days is (3d+7). Therefore, the expression that represents the total number of items that have been collected after d days would be
4d + 5 + 3d + 7
= 4d + 3d + 5 + 7
= 7d + 12
The equation is already solved for you basically
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.




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.


Therefore, the rounded measurement of rain would be 0.023 meters.
Answer:
8000•1.05 8000(1.05)¹
(8000•1.05)•1.05 8000(1.05)²
((8000•1.05)•1.05)•1.05 8000(1.05)³
(((8000•1.05)•1.05)•1.05)•1.05 8000(1.05)⁴
8000(1.05)^t
