Answer:
1 is neither prime nor a composite number because it only has 1 divisor, 1 and 1, and it doesn't have more than 2 integral divisors, like stated, it only has 1. So it falls in neither category.
Answer:
4.7 miles
Step-by-step explanation:
if she walks 10,000 steps at 30 inches then we have 300,000 inches...
30000 divided by 63360 (inches in a mile)
4.7 rounded
Answer:
3
Step-by-step explanation:
The scale factor of ABC to DEF is the number you need to multiply a corresponding side of ABC to get one of DBC. We are given the two triangles are similar, so we can say that sides AB and DE are proportional. We are looking for the number we need to multiply AB by to get DE. From this relation, we can get the equation:
AB * x = DE
where x is our scale factor. We can substitute in the values of AB and DE, and solve for x:
5x = 15
x = 3
Therefore, the scale factor is three. This means that you can multiply any side of ABC by 3 to get a side of DEF.
Answer:
Step-by-step explanation:
hello :
let : three consecutive even integers : 2n , 2n+2 , 2n+4
a) the polynomial is : 2n(2n+2)(2n+4) = 39168
but : 39168=2^8 ×3²×17 =2^5×2×17×9×2^2 because : 2^8=2^5×2×2^2
39168=32×34×36 because : 2^5=32 and 2×17 =34 and 9×2^2 =36
conclusion : three consecutive even integers are : 32 ,34 ,36
When you reflect FGH across the y-axis, you are left with the vertices of F'G'H at (2, -1) (-2, 2) (-4, -3)
The correct answer is b.
Hope this helps =)
