Answer:
20 chairs
Step-by-step explanation:
After 136 people are seated in the bleacher, there can be 514 people seated in chairs. We know that 514 = 25×20 +14, so there can be 20 rows of 25 chairs. We require an equal number of chairs in each row, so there cannot be some rows with 21 chairs, nor can there be a 26th row with 14 chairs.
There can be 20 chairs in each row.
331.3%
Convert 53/16 to simplest form, 3 5/16, convert 5/16 into numbers —> 0.3125
Take the whole number and add it into the ones place: 3.3125
Move the decimal into two places then round to the nearest tenth: 331.3
Answer: x=-7
Step-by-step explanation:
1. distribute the 2 to (3x-12) >>>> 8x+6x-24=-122
2. add 8x and 6x to get 14x >>>> 14x-24=-122
3. add 24 to both sides>>>> 14x=-98
4. divide 14 by both sides>>>x=-7
We have that
<span>y = -x</span>²<span>+8x
we know that
when the ball hint the ground is the x-intercepts of the graph
the x-intercepts is for y=0
so
0=-x</span>²+8x--------> x²-8x=0----> x*(x-8)=0
the solution is
x=0
x=8
the x intercepts are the points (0,0) and (8,0)
the distance between the x intercepts points =[8-0]-----> 8 ft
the answer is
8 ft
