Answer:
1/10
Step-by-step explanation:
The value of any digit is found by setting all other digits to zero.
The value of the 2 in 43,290 is 200.
The value of the 2 in 32,865 is 2,000.
200 is 200/2000 = 1/10 times 2000
The value of 2 in 43,290 is <u>1/10</u> times the value of 2 in 32865.
Answer:
V=251.2
Step-by-step explanation:
V=3.14•r*2•h
V= 3.14• 4*2•5
V= 3.14• 16•5
V=3.14•80
V=215.2
Answer:
<em> All real numbers less than or equal to 7</em>
Step-by-step explanation:
we have
f(x)=-(x+3)^2+7
we know that
The function is a vertical parabola open downward
The vertex is the point ( -3,7 )
The vertex is a maximum
The range is the interval-----------> (-∞,7]
That means
All real numbers less than or equal to
Multiply all terms by x and cancel
xx+-15=2x
x^2-15=2x simplify both sides
x^2-15-2x=2x-2x subtract 2x from both sides
x^2-2x-15=0
(x+3)(x-5)=0 factor left side of equation
x+3=0 or x-5=0 set factors equal to 0
x=-3 or x=5
hope this helps!
Well 151 divided by 24 is 6 remainder 7 so the mixed number would be 6 and 7/24
