-5 + x = 7 1/3
X = 7 1/3 + 5
X = 12 1/3
A-- (x)(.10)= New cost
B--New cost-2000= Cost after 10% discount and 2,000 discount
C--You'll have find what number mulitiplied by(.10) equals $18,000
D-- $18,000 is the price with the $2,000 already taken out, so now you just do 18,000(.10)=
Answer:
- trailing zeros are dropped
- 1846 beats
- 42×(selling price for 1 tin)
Step-by-step explanation:
41. The product of 0.25 and 0.4 is 0.100, with three decimal places. Trailing zeros are usually dropped--except when they are used to indicate significant digits in a calculation. Hence, the usual presentation of the result is ...
0.25 × 0.4 = 0.1
__
42. To find total beats, multiply beats per second by seconds.
(52 beats/second)(35.5 seconds) = (52)(35.5) beats = 1846 beats
The hummingbird's wings will beat 1846 times in 35.5 seconds.
__
43. To find total sales for the week, multiply the price of a tin of popcorn by the number sold in the week (42).
