Answer:
Step-by-step explanation:
it makes 253 copies in 5 mins 45 seconds
that is to say, 253 copies in 345 seconds
In 1 minute (60 seconds) it will make X copies.
Lets draft an equation to easily express and simplify the problem.
253 copies = 345 seconds
X copies = 60 seconds
lets cross multiply and solve for X
Theefore:
x * 345 = 254 * 60
345x = 15,240
divide through by 345
x = 15240 / 345
x = 44.17
therefore, the copying machine makes approximately 44 copies per minutes
Answer:
6hrs
Step-by-step explanation:
60km x 5 = 300km distance
50km x 6 = 300km distance
When working with logarithms, remember that a subtraction sign means you can divide.
log(400) - log(4) can be turned into log(400/4), which is further simplified to log(100).
y=x^2-2x-15 (1) y=8x-40 (2)
8x-40=x^2-2x-15
X^2+10x-25=0
(x-5)^2
×=5 y=0
4 in roman numerals is IV. V = 5, and the I is like taking one off the 5. If it was VI, it would be 6, like adding 1. So, IV is 4. The patient will take IV mLs.
