For 1. To estimate how many sports cards Alberto had, you would round each number to the nearest ten, so 318 would become 320. 273 would then become 270. You would then add those two and would get 590. So, Alberto had 590 sports cards (estimated). If you were looking for the actual answer (not estimated) , you would get 591.
Answer:
the length of the thread remaining is 790 cm
Step-by-step explanation:
Given;
original length of the thread, L₀ = 10 m = 1000 cm
the length of the thread used, L₁ = 210 cm
The length of the thread remaining is calculated as follows;
ΔL = L₀ - L₁
ΔL = 1000 cm - 210 cm
ΔL = 790 cm
Therefore, the length of the thread remaining is 790 cm
Answer:
$2399.99
Step-by-step explanation:
the price of the tv is discounted by 25%
that is the same as saying the tv is 75% of its original price
so we take $1799.99/75 to see what one percent of the price is
$1799.99/75=23.9998
then we take 23.9998*100 to see what the original price was
23.9998*100=2399.986667 and then we round to the nearest hundredth
so 2399.99
