1) 4 divided by 7 = 0.57
2) 4 times 5 = 20 and 4 times 8 = 32
3) 20 plus 32 = 52
4) 0.57 times 52 = 29.64
5) answer : 29.64
i hope this is correct. i tried to break it down.
Answer:
24
Step-by-step explanation:
The area is calculated by multplying radius (half of diameter) by itself and then with number pi
the area for this circle is given as
144π m^2
144 is the squared form of 12 if the radius is 12 the diameter is 24
Whole numbers, integers, rational numbers, natural numbers, real numbers
All of those are correct
Answer:
cost of ribeye steak dinners = $10.36
cost of grilled salmon= $11.581
Step-by-step explanation:
Let the cost of one steak dinners be x
Let the cost of one grilled salmon be y
One a particular day the waitress sells 12 ribeye steak dinners and 39 grilled salmon for a total is $575.53 which can be written in equation as
12(x)+39(y)= $575.53-------------------------------------(1)
On another day she sells 25 ribeye steak dinners and 13 grilled salmon dinners totals to $582.43.This can be represented as
25(x)+ 13(y)= $582.43-------------------------------------(2)
solving the equation (1) and (2)
eq(1) x 1![12x+39y= 575.53](https://tex.z-dn.net/?f=12x%2B39y%3D%20575.53)
eq(2) x 3
-------------------------(3)
Subtracting these equation we get,
![113x=1171.76](https://tex.z-dn.net/?f=113x%3D1171.76)
![x=\frac{1171.76}{113}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1171.76%7D%7B113%7D)
x= 10.36
Now substituting this in equation (1)
![12(10.36)+39(y)= $575.53](https://tex.z-dn.net/?f=12%2810.36%29%2B39%28y%29%3D%20%24575.53)
![123.84+39y=575.53](https://tex.z-dn.net/?f=123.84%2B39y%3D575.53)
![39y=575.53 - 123.84](https://tex.z-dn.net/?f=39y%3D575.53%20-%20123.84)
![y=\frac{451.69}{39}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B451.69%7D%7B39%7D)
y=11.581
Answer:
Yep thats right
