A 40 is the lowest she can make and that would give her exactly a 70 average.
Answer:
D
-29
Step-by-step explanation:
Problem 1
In the first hour, the number of bacteria is 22
In the second hour,the number of bacteria is 44
It looks like the formula is some multiple of 22
That means you should pick D
Problem 2
n = 12
a = 15
d = - 4
an= 15 + (n - 1)*d
a12 = 15 + 11*(-4)
a12 = 15 - 44
a12 = - 29
We have been given a graph that models the cost of a cheese pizza with extra toppings at two different restaurants. Now using the graph, we have to find about how many pizza toppings must be added to make the cost of the pizzas from both restaurants equal.
To find that we just have to look at the intersection point of both graphs.
If you look carefully then you will find that both graph intersect at the point where x-coordinate is 5.
Hence final answer is 5 toppings.
Step-by-step explanation:
there must be something wrong or missing in your problem description.
what I can read here :
-97 - 7 when divided by 2
-97 - 7 = -104
this divided by 2 is -52.
but there is no such answer.
so, the provided answers and the problem description do not fit to each other.
When graphing an inequality, it is often hard to see what side is shaded, to signal which solutions work. Try out (0, 0) into the equation and if it works, it is a solution, so shade the side that has the origin in it.
