Answer:
Medium: 4 and Large: 6
Step-by-step explanation:
Factor pairs that are equivalent to 10:
1,9
2,8
3,7
4,6
5,5
and so on. So you could do 2.4*9 and 1.8*1. If that doesn't work, switch it around. This coud probably take 1/2 of a hour or more. But it'll be worth it if it's a grade. :3
In the end, I'm pretty sure you should be able to get the answer:
Medium cups: 4
Large cups: 6
1.8 multiplied by 4 would get you 7.2 and 2.4 multiplied by 6 would get you 14.4. If you add them all up, you would get a 21.6! If you didn't, check your math again.
Answer:
2π r = Circumference formula
2π r = 18
r = 18/2π
r= 2.86cm
Hope this helps :)!
I'd appreciate if you'd mark me brainliest because ive been stuck on the same rank for wayyy too long :(
Goodluck! :)
F+s=95
f=s+27
s+27+s=95
2s=95-27
sixth graders = 34
fith graders = 61
For this case we have the following system of equations:
![5x + 3y = 17\\-8x - 3y = 9](https://tex.z-dn.net/?f=%205x%20%2B%203y%20%3D%2017%5C%5C-8x%20-%203y%20%3D%209%20%20)
We can Rewrite the system of equations of the form:
![Ax = b](https://tex.z-dn.net/?f=%20Ax%20%3D%20b%20%20)
Where,
A: coefficient matrix
x: incognita vector
b: vector solution
We have then:
![A=\left[\begin{array}{ccc}5&3\\-8&-3\end{array}\right]](https://tex.z-dn.net/?f=%20A%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D5%263%5C%5C-8%26-3%5Cend%7Barray%7D%5Cright%5D%20%20)
![x=\left[\begin{array}{ccc}x\\y\end{array}\right]](https://tex.z-dn.net/?f=%20x%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dx%5C%5Cy%5Cend%7Barray%7D%5Cright%5D%20%20)
![b=\left[\begin{array}{ccc}17\\9\end{array}\right]](https://tex.z-dn.net/?f=%20b%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D17%5C%5C9%5Cend%7Barray%7D%5Cright%5D%20%20)
Then, the determinant of matrix A is given by:
![|A|=(5)(-3)-(3)(-8)\\](https://tex.z-dn.net/?f=%20%7CA%7C%3D%285%29%28-3%29-%283%29%28-8%29%5C%5C%20)
![|A|=-15+24](https://tex.z-dn.net/?f=%20%7CA%7C%3D-15%2B24%20)
![|A|=9](https://tex.z-dn.net/?f=%20%7CA%7C%3D9%20)
Answer:
The determinants for solving this linear system are:
![|A|=9](https://tex.z-dn.net/?f=%20%7CA%7C%3D9%20)
