Answer:

Jackie, 91, 97 is prime.

Step-by-step explanation:

Remember that a number greater than 2 is NOT prime if it is divided by any  number different than 1, for example 6 is NOT prime because 3 divides 6. 7 is prime because the only divisors of 7 are 1 and 7.

So for the nineties 90 is divisible by 45.

91 is divisible by 7

92 is divisible by 2

93 is divisible by 3

94 is divisible by 2

95 is divisible by 5

96 is divisible by 2

97 IS PRIME, is just divisible by 1 and 97

98 is divisible by 2

99 is divisible by 3

True or false? in order to inscribe a circle in a triangle, the circle's center must be placed at the circumcenter of the triang
Dvinal [7]

Answer:

<h2>False.</h2>

Step-by-step explanation:

A inscribe circle in a triangle means to draw the biggest circle possible inside such triangle. To do that perfectly, we first have to find the incenter of the circle, which is the intersection of all three internal bisector of the triangle, that point is the center of the inscribed circle.

Therefore, the statement is false.

In addition, a circumcenter allow to perfectly draw a circumscribed circle, which is outside the triangle, which is not the case here.

An image showing the inscribed circle is attached.
