X^2=256
x=±√256
x=±16
x=-16 and 16
1760 divided by 0.07 = the cost
So the answer is 25142 (rounded)
Answer:
48 packages
Step-by-step explanation:
Hello There!
The first step is to find out how many uniforms they need to do so we multiply 127 and 3
3x127=381
Then we divide it by 8 ( because that's how many uniforms are sold in one package.)
381/8=47.625
you cannot have a 6th of a package so we just round to the nearest whole
so we can conclude that they will need 48 packages

Answer:
606 feet
Step-by-step explanation:
The fireword has a 5-second fuse, meaning that's how long it will take to explode.
Given the polynomial -16t² + 200t + 6, where t is the time in seconds
We need to subsitute 5 sec. (as stated in the question) for t in the polynomial, to find how high the fireworks will be when it explodes :
-16t² + 200t + 6 <== substitute 5 for t
-16(5)² + 200(5) + 6 <== square the exponent first
-16(25) + 1000 + 6 <== multiply
-400 + 1000 + 6 <== add
-400 + 1006 <== add
606 feet <== final answer
This means that it will be 606 feet high before it explodes.
Hope this helps!
750 is the regular price minus the 25% and 15% it will equal 478.125..(round up 125 to 13 and your answer is 478.13
