It would be 2.1×10 to the power of 13
Part A: Write an expression that Robie can use to determine how much black pepper is needed for 6 batches.
The first thing you should know in this case is the amount of pepper available and the amount of black pepper in each batches.
Available = s 2/3 teaspoon
Batches = 1/8 teaspoon
Let
x = number of batches:
y = black pepper
The expression is then:
y = 1/8x
0 <= x <= 6
---
Part B: Draw a Model to show how Robbie can find the product from Part A (do not say how to draw the model just say how to solve the expression in Part A.)
You must graph the line of part A:
y = 1/8x
Then, check for x = 6 the value of y to know how much black pepper is needed for 6 batches.
----
Part C: Does Robbie have enough black pepper for 6 batches of the soup? Explain your reasoning. (<--- PLEASE EXPLAIN.)
Substituting x = 6
y = 1/8 (6)
y = 6/8
y = 3/4
3/4> 2/3
Robbie has not enough black pepper for 6 batches of the soup
Answer:
a = 195 ; c = 615
Step-by-step explanation:
So, you want to start by forming your equations...
I will use 'c' for children and 'a' for adults for my variables
3a + 30 = c
(this is because of the info that 30 more tickets than 3 times the amount of children's were sold than adult)
then for equation 2:
3c + 5a = 2820
(this is because of the prices of the tickets and the total money raised)
Then, plug in the equation for c
Your equation should look like:
3(3a + 30) + 5a = 2820
You get:
(9a +90) + 5a = 2820
Then:
14a = 2730
So:
a = 195 adult tickets sold
Plug in a, to find c:
3 (195) + 30 = c
585 + 30 = c
c = 615 children tickets sold
Answer: The first box
Step-by-step explanation:
V represents volume and r represents radius
So V(r) represents the volume of the basketball with respect to radius
