Answer:
12.3
Step-by-step explanation:
A^2 + B^2 = C^2
11^2 + 4.5^2 = C^2
132 + 20.25 = C^2
152.25 = C^2
Square root of 152.25 = 12.3

Answer:
![c=18.90-2.1r](https://tex.z-dn.net/?f=c%3D18.90-2.1r)
Step-by-step explanation:
<u><em>The complete question is</em></u>
A chef bought $17.01 worth of ribs and chicken. Ribs cost 1.89 per pound and chicken costs 0.90 per pound. The equation 0.90 +1.89r = 17.01 represents the relationship between the quantities in this situation.
Show that each of the following equations is equivalent to 0.9c + 1.89r = 17.01.
Then, explain when it might be helpful to write the equation in these forms.
a. c=18.9-2.1r. b. r= -10÷2c+9
we have that
The linear equation in standard form is
![0.90c+1.89r=17.01](https://tex.z-dn.net/?f=0.90c%2B1.89r%3D17.01)
where
c is the pounds of chicken
r is the pounds of ribs
step 1
Solve the equation for c
That means ----> isolate the variable c
Subtract 1.89r both sides
![0.90c=17.01-1.89r](https://tex.z-dn.net/?f=0.90c%3D17.01-1.89r)
Divide by 0.90 both sides
![c=(17.01-1.89r)/0.90](https://tex.z-dn.net/?f=c%3D%2817.01-1.89r%29%2F0.90)
Simplify
![c=18.90-2.1r](https://tex.z-dn.net/?f=c%3D18.90-2.1r)
step 2
Solve the equation for r
That means ----> isolate the variable r
Subtract 0.90c both sides
![1.89r=17.01-0.90c](https://tex.z-dn.net/?f=1.89r%3D17.01-0.90c)
Divide by 1.89 both sides
![r=(17.01-0.90c)/1.89](https://tex.z-dn.net/?f=r%3D%2817.01-0.90c%29%2F1.89)
Simplify
![r=9-0.48c](https://tex.z-dn.net/?f=r%3D9-0.48c)
therefore
The equation
is equivalent
The equation is helpful, because if I want to know the number of pounds of chicken, I just need to substitute the number of pounds of ribs in the equation to get the result.
Answer:
A) P(Green) = 1/8, 0.125, 0r 12.5%
P(Orange) = 1/2, 0.5, or 50%
B) P(Not Yellow) = 3/4, 0.75, or 75%
Step-by-step explanation:
A) P(Green) = 1/8, 0.125, 0r 12.5%
P(Orange) = 1/2, 0.5, or 50%
B) P(Not Yellow) = 3/4, 0.75, or 75%
The best way to estimate large numbers is to find out how many units is in the number. For example, when you are dealing with millions you need to estimate the number of items closest to the large number. Ex. 1, 899,000 estimating this number is basically saying close to 2 million because the number to the right is higher then 5 so the number goes up.
