Answer:
A. José, Huang, Sam
Explanation:
José’s time is faster than the oldest boy, so he came in 1st or 2nd. It is given that José did not come in second, so he came in first. The remaining places are second and third. It is stated that Huang did not come in third, so Huang came second and Sam came third. The order is José, Huang, and then Sam.
Answer:
Yes, it is a right triangle.
Step-by-step explanation:
a^2+b^2=c^2
The longest side is the hypotenuse so c^2 would be 90.
72^2+54^2=90^2
72 and 54 can be either a or b.
Solve for all exponents: 5184+2916=8100.
That equation is true, so the triangle is a right triangle.
By geometry, there is a relationship between the tangent PA and the segments PB and PE, namely
PA^2=PB*PE
so
PE=PA^2/PA=6^2/4=9
BE=PB-PE=9-4=5
Answer: The solution is 
Step-by-step explanation:
since we have given that
we need to solve it using area models:
As we know that "In fractions, division is changed into multiplication by reciprocating the next term to make it possible to solve":
So, It turns into model of area "Area of rectangle "
Now, verifying by using numerical operations only.
Hence, verified.
