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
5. 8:21
You do 21-13 to get 8
6. 26:1
Answer:-1/32
Step-by-step explanation:
First term=a=1024
Common ratio=r=-512/1024
r=-1/2
Using them formula
Tn=a x r^(n-1)
T16=1024 x (-1/2)^(16-1)
T16=1024 x (-1/2)^15
T16=1024 x -1/32768
T16=-1024/32768
T16=-1/32
Answer:
B) False.
Step-by-step explanation: 8 to the power of 2 plus 10 to the power of 2 gives you 164 but 18 to the power of 2 equals 324. In order to make a right triangle the answers have to be the same, but they are not so Paul cannot make a right triangle. Hope this answered your question.
