Answer:
We conclude that Seth can make the model of the house on 9 different ways.
Step-by-step explanation:
We know that Seth uses 17 linking cubes to make a model house. The model house is in the shape of a rectangle and is one cube high.
We calculate how many different ways could Seth make the model of the house:
We conclude that Seth can make the model of the house on 9 different ways.
7) So when x=6 then z=72, they are directly proportional, so if I multiply the first with a number, then I have to multiply the second with the same number.
6 becomes 13 (x) /multiplied with about 2.167/
72 becomes 156(y) /multiplied with about 2.167/
8) Inversely proportional, so if I multiply the first with a number, then I have to divide the second with the same number.
6 becomes 13 (x)
2 becomes ~0.92307(y) /round it to the thousandths place and you get 0.923/
Answer:
25.92 foot strides
Step-by-step explanation:
The man will take 120/5 = 24 five foot stride to cover the initial 120 foot advantage of the child.
Within this time, the child would have covered an additional 24/5 x 2 = 9.6 extra foot stride.
Within this 9.6 food stride of the child, the man will have to take an additional 9.6/5= 1.96 strides.
Total foot stride by the man will be 24 + 1.96 = 25.92 foot strides.
Number: n
square of number: n^2
sum of n and n^2 is n+n^2=20
Rewriting this equation, we get n^2+n-20=0 = (n+5)(n-4) = 0
Then n+5=0 and n-4=0, so n = -5 and n = 4.
You must check both results. It could happen that both are correct, or that only one is correct.
A number tripled mean you have to multiply it by 3
so the answer is
3 times a number q or...
3q
