Answer:
24 possible dishes
Step-by-step explanation:
Given
Total
Selection
Required
Determine the number of possible combo
Rita wants to select 1 of 4 meat types,
So, the number of selections is:
Rita wants to select 2 of 3 cheese types,
So, the number of selections is:
Rita wants to select 1 of 2 cheese types,
So, the number of selections is:
The total number of selections is:
Using
We have:
<em>Hence, there are 24 possible dishes</em>
The answer that goes in the blank is: 3
Note: The "pi" portion is already taken care of, so there's no need to enter it in the box.
============================================================
Explanation:
The distance around the entire circle is found by the circumference formula
C = 2*pi*r
where r is the radius.
In this case, r = 27, so,
C = 2*pi*r
C = 2*pi*27
C = 2*27*pi
C = 54*pi
The full distance around the circle is exactly 54pi units
We only want a small portion of it. We only want 20/360 = 2/36 = 1/18 of that distance
So multiply (1/18) by 54pi and we get...
(1/18)*(54pi) = (54/18)*pi = 3pi
So the length along the curve from A to B (or vice versa) is exactly 3pi units.
To solve a problem like this, you will need to use substitution or elimination. For the sake of an example I will solve this using substitution.
First, solve one of the equations for x or y:
3x-5y=-39
3x=-39+5y
X=(-39+5y)/3
Then substitute for the value of x in the second equation:
6x+2y=-42
6((-39+5y)/3)+2y=-42
Solve for y:
-78+10y +2y=-42
-78+12y=-42
12y=36
Y=3
Once you've solved for y, you can plug in it's value to find x:
X=-39+5(3)/3
X=-24/3
X=-8
So, we can conclude that the correct answer is B. (-8,3)
Answer:
$5
Step-by-step explanation:
So we know that altogether Michael paid $12 right?
So if his brother's price is x then his price is x+2
so 2x+2=12 x=5
Michael's brother's price was $5
and his was $7
Answer:
The answer to your question is time = 20 min
Step-by-step explanation:
Data
Candace = 480 ft/min
time = 5 min
Brother = 660 ft/min
Process
1.- Calculate the distance traveled by Candace in 5 min
distance = speed xtime
= 480 x 5
= 2400 ft
2.- Write the equations to help solve the problem
Candace distance = 2400 + 480t
Brother distance = 600t
3.- Solve by equality
2400 + 480t = 600t
2400 = 600t - 480t
2400 = 120t
t = 2400/120
t = 20 min
4.- I will solve the equation given
480t = 660(t - 112112)
480t - 660t = -112112
-120t = -112112
t = -112112/-120
t = 934 h I think there is a mistake in the formula you
wrote.
