Answer: Each flower costs $0.38.
Step-by-step explanation:
1 dozen = 12 units
Flowers in each tray = 3 dozen = 3 x 12 = 36
Flowers in 20 trays = 20 x 36 = 720
Price of 20 trays = $ 273.60
Price of each flower = (Price of 20 trays ) ÷ (Flowers in 20 trays)
= 273.60 ÷ 720
= $ 0.38
Hence, each flower costs $0.38.
1. 300 T-shirt in 10 Minutes, thus: 300/10=30 T-shirts per minute.
3. 2 Liters in 10 seconds, thus: 2/10 = 0.2 Liters or 2 deciliters each second
4. Bill is paid $200 for 5 days, thus, $200/5 = $40 per day.
Answer:
(x+1) (x^2+1)
Step-by-step explanation:
x^3+x^2+x+1
Factor by grouping
x^3+x^2 +x+1
Factor out x^2 from the first group and 1 from the second group
x^2( x+1) + 1( x+1)
Factor out (x+1)
(x+1) (x^2+1)
80% of 25
percent means parts out of 100
'of' means multiply
80% of 25 means
80/100 times 25=40/50 times 25=20/25 times 25=20
answer is 20 problems
Answer:
Step-by-step explanation:
We can simplify (cross multiply) to get ![xy^2=wz](https://tex.z-dn.net/?f=xy%5E2%3Dwz)
Then we easily simplify to get ![y=\sqrt{\frac{wz}{x}},\:y=-\sqrt{\frac{wz}{x}};\quad \:w\ne \:0,\:x\ne \:0](https://tex.z-dn.net/?f=y%3D%5Csqrt%7B%5Cfrac%7Bwz%7D%7Bx%7D%7D%2C%5C%3Ay%3D-%5Csqrt%7B%5Cfrac%7Bwz%7D%7Bx%7D%7D%3B%5Cquad%20%5C%3Aw%5Cne%20%5C%3A0%2C%5C%3Ax%5Cne%20%5C%3A0)
