Frank has devised a formula for his catering business that calculates the number of meatballs he needs to prepare.

the formula is m=4a +2c, where c= number of children; m= number of meatballs; a= number of adults.

q: how many meat balls are required for a party of 25 adults and 6 children?

112 meat balls are required for a party of 25 adults and 6 children.

Step-by-step explanation:

As per the statement:

Frank has devised a formula for his catering business that calculates the number of meatballs he needs to prepare.

The formula is given by:

where;

c= number of children;

m= number of meatballs;

a= number of adults.

We have to find  how many meat balls are required for a party of 25 adults and 6 children.

⇒a = 25  and c = 6

then;

Therefore, 112 meat balls are required for a party of 25 adults and 6 children.

  about 5.6 days

step-by-step explanation:

we can fill the given information into the decay equation and solve for the value of t at which half the sample remains.

the half-life is about 5.6 days.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
