Answer:
solution:
x = pounds of cashews = 20
y = pounds of peanuts = 70
Step-by-step explanation:
x = pounds of cashews
y = pounds of peanuts
---
4.75x + 2.50y = 3.00*90
x + y = 90
---
put the system of linear equations into standard form
---
4.75x + 2.50y = 270
x + y = 90
Answer:The mean increases but the median stays the same.
Step-by-step explanation:
201 + 233 + 237 +255 +269+277+306 mean is 257 and median is 255
225 +233 + 237 +255 +269+277+306 mean is 260 and median is 255
First,you do,2/5+2/3,but since you will need a common denominator,you will find the least common denominator for 5 and 3.The LCD(Least Common Denominator) will be 15 since both 5 and 3 could go in 15.Now,the equation looks like this: 2/15+2/15 since whatever you do to the bottom numbers,you NEED to do to the top numbers:2 and 2.Now you will need to do,2x3,since 5x3=15 and the answer to 2x3=6 then you do 2x5,since 3x5=15 the answer is 10 now the equation looks like this:6/15+10/15 now you add them together,and the answer will be 16/15 and if you want the answer to be a mixed number,it would look like this: 1 1/15. Hope this helps!
No it is not a perfect square
To find out how many liters of energy drink Coach Donavan bought you need to multiply how much liters are in one bottle by how many bottles he bought.
9/10 x 15
9/10 x 15 is 13.5 or 13 and 1/2
So Coach Donavan bought 13 and a half liters of energy drink.
