The third option is the answer
Answer:
79
Step-by-step explanation:
60<xy<100
y -2 =x
if it is prime
y cannot be even
so y could be 1,3,5,7,9
x would then be 9,1,3,5,7
but to be between 60 and 100
x must be 7 or 9
so the number must be 79 or 57
57 is not prime so
the number is 79
Answer:
A
Step-by-step explanation:
ok, without reading through any of the answers lets see what we can get just from looking at that picture.
We can see that the angles being bisected are on a straight line.
A straight line is 180 degrees.
We know that you have to add both angles together to get 180.
The answer has to equal 180.
A is the only option that offers that.
Find all the areas and add them together
Base Rectangle : LxW = 14 x 12 = 168
Bases Triangles (2) 2x (8x12)/2 = 96
2 Lateral rectangles 14x10 =140 (double) = 280
Surface Area = 168 +96 + 280 = 544
Answer:
10.2 inches.
Step-by-step explanation:
First, assume the two sides are legs, square both sides and add them,:
144+225=369
square root of 369 is the hypotenuse
suppose 15 is the hypotenuse (it can't be 12 since the hypotenuse is the longest)
Then 12^2+x^2=15^2
x^2=81
x=9, a 9-12-15 right triangle.
So the third side can be 9 or square root of 369 =19.2 to nearest tenth.
The difference is 19.2-9=10.2 inches.
