We need to find the height of the mirror to solve this problem. We know the area and width, so using the formula
, we have
. Then:
Since
is less than 5, the mirror will fit.
Subtract 1/2 mile for the two-way trip of walking. Then multiply the 3 by 2 to get how far the bus drove.
so the answer would be:
6
Hope this helps
f(x) = 4x + 4 means that if we put an x into our function, a 3x + 4 come out.
So in this problem, we're putting a 2 into our function which
means that a 3(2) + 1 comes out which simplifies to 6 + 1 or 7.
So f(2) = 7 or the value of the function at 2 equals 7.
Step-by-step explanation:
5r+1=a(m+r)
or , 5r+1=am+ar
or, 5r-ar=am-1
or , r(5-a)=1(am-1)
: <u>r</u><u> </u> =<u>(</u><u>am-1)</u>
1 (5-a)
Number of 1/2-inch cubes length-wise = 8 1/2 ÷ 1/2 = 17
Number of 1/2-inch cubes width-wise = 5 1/2 ÷ 1/2 = 11
Number of 1/2-inch cubes height-wise = 2 1/2 ÷ 1/2 = 5
Number of 1/2-inch cubes = 17 x 11 x 5 = 935
------------------------------------------------------------
Answer: 935 1/2-inch cubes are needed.
