Answer:
-2755 plants
-40mg is left.
Step-by-step explanation:
Given the fertilizer amount is 1.08kg, and the amount per plant per year is (4*98mg):
#convert the weight of the fertilizer into grams then divide by quantity per plant to determine number of plants;
![Number \ of \ plants=\frac{Fertilizer \ Amount}{Quantity \ per \ plant}\\\\=\frac{1.08\times 1000000}{98\ mg\times 4}\\\\=2755.1\approx2755](https://tex.z-dn.net/?f=Number%20%5C%20of%20%5C%20plants%3D%5Cfrac%7BFertilizer%20%5C%20Amount%7D%7BQuantity%20%5C%20per%20%5C%20plant%7D%5C%5C%5C%5C%3D%5Cfrac%7B1.08%5Ctimes%201000000%7D%7B98%5C%20mg%5Ctimes%204%7D%5C%5C%5C%5C%3D2755.1%5Capprox2755)
-There are 2755 plants planted.
-We subtract the fertilizer used from the total to find what is left:
![Left=Total -Used\\\\=1080000\ mg-(2755\times98\times4)\\\\=40\ mg](https://tex.z-dn.net/?f=Left%3DTotal%20-Used%5C%5C%5C%5C%3D1080000%5C%20mg-%282755%5Ctimes98%5Ctimes4%29%5C%5C%5C%5C%3D40%5C%20mg)
Hence, 40 mg of the fertilizer is left over.
Answer:
Each senior citizen ticket costs $7 and each child ticket costs $5.
Step-by-step explanation:
Let,
x be the price of each senior citizen ticket
y be the price of each child ticket
According to given statement,
x+4y=27 Eqn 1
6x+8y=82 Eqn 2
Multiplying Eqn 1 by 2
2(x+4y=27)
2x+8y=54 Eqn 3
Subtracting Eqn 3 from Eqn 2
(6x+8y)-(2x+8y)=82-54
6x+8y-2x-8y=28
4x=28
Dividing both sides by 4
![\frac{4x}{4}=\frac{28}{4}\\x=7](https://tex.z-dn.net/?f=%5Cfrac%7B4x%7D%7B4%7D%3D%5Cfrac%7B28%7D%7B4%7D%5C%5Cx%3D7)
Putting x=7 in Eqn 1
7+4y=27
4y=27-7
4y=20
Dividing both sides by 4
![\frac{4y}{4}=\frac{20}{4}\\y=5](https://tex.z-dn.net/?f=%5Cfrac%7B4y%7D%7B4%7D%3D%5Cfrac%7B20%7D%7B4%7D%5C%5Cy%3D5)
Hence,
Each senior citizen ticket costs $7 and each child ticket costs $5.
Answer:
SAS
Step-by-step explanation:
It tells you that there are two sides equal, and they both have a 90 degree angle. This means that they are congruent because of side, angle, side, or SAS.
