Answer:
Tamar
Step-by-step explanation:
Since we're rounding to the hundredths place, we need to see if the thousandths place is greater or equal to 5. Since it is less than 5, we round down to 72.63.
Answer:
perimeter of a circle=2πR
Change into slope-intercept form:
y= -3/4x + 5
We will be using the point slope formula to write the perpendicular equation:
y - y1 = m (x - x1)
y + 2 = 4/3(x + 3)
y + 2 = 4/3x + 4
y = 4/3x + 2
Answer:
y = 4/3x + 2
Answer:
$880
Step-by-step explanation:
This is called a system of equations!! Here's how to do it:
1. Make Equations
In this case, the equations would be
- p+c=64 (this is saying that pepperoni pizzas plus cheese pizzas equal 64, which we got from the question.)
- 1/3c=p (this is telling us that he sells 1 pepperonis for 1/3 cheese pizza)
2. Solve the system of equations
For this problem, we will substitute 1/3c for p. The problem becomes
Then you divide by 4/3 to get p by itself:
Now substitute 48 for p in the first equation.
3. Find the money amounts
Now that you know that pepperoni pizzas equal 48, and cheese equals 16, this is easy.
- Multiply 16*10 to get the cheese cost. ($160)
- Multiply 15*48 to get the pepperoni cost ($720)
- Then add those to get the total!
