Answer:
36 tiles
Step-by-step explanation:
There will be 6 tiles in each direction, so the tiles covering the floor form a 6×6 array. The number needed is 6×6 = 36.
X is the number
<span>The sum of two numbers is 11, so other number is : 11 - x
</span><span>The sum of their squares is 65
</span>
x^2 + (11 - x)^2 = 65
x^2 + 121 - 2(x)(11) + x^2 = 65
2x^2 - 22x + 121 = 65
2x^2 - 22x + 121 - 65 = 0
2x^2 - 22x + 56 = 0
2(x^2 - 11x + 28) = 0
2(x - 7)(x -4 ) = 0
x - 7 = 0
x = 7
x - 4 =0
x =4
answer: the numbers are 4 and 7
double check:
<span>sum of two numbers is 11:
4 + 7 = 11
</span><span>The sum of their squares is 65
</span><span>4^2 + 17^2 = 16 + 49 = 65
</span>
The amount of grams of fiber that Jodi should eat to meet the recommended daily amount of fiber is 12 grams.
<h3>How many more grams of fiber should Jodi eat?</h3>
The first step is to convert milligrams to grams.
1 milligram = 0.001 grams
25,000 x 0.001 = 25
Now subtract the recommended amount from the quantity eaten:
25 - (8 + 4 + 1 ) = 12 grams
