Answer: 1.8 servings of soybean and 1.2 servings rice will be needed.
Step-by-step explanation:
Let x be the number of soybeans and y be the number of rice.
Then , According to the question , we have
Multiply 2 on both the sides of equation (2), we get
Subtract equation (2) from equation (3), we get
Put x = 1.8 in equation (2), we get
Hence, 1.8 servings of soybean and 1.2 servings rice will be needed.
Answer: 52.5cm²
Step-by-step explanation:
Firs, you have to split this composite shape into two separate shapes; a rectangle and triangle.
To work out the area of the rectangle you would have to do 8x5=40.
To work out the area you would have to find out the height of it first. So, to do this you would have to do 1+2=3 then do 8-3=5. Now we know the height is 5.
Then you have to use the formula base times height divided by 2 (b×h/2). So 5×5=25 then 25÷2=12.5
To then find the total area of this composite shape you would have to add the two areas together. So 40+12.5=52.5cm²
Hope this helps :)
Answer:
3%
Step-by-step explanation:
This equation represents exponential decay. Whenever the base is less than 1, the function represents decay. When the base is greater than 1, the function represents growth. In this case, the base is .97 which is less than 1, representing decay.
The formula for exponential decay is y=a(1-r)x.
r is the decay rate, expressed as a decimal.
In this case, r = .03 which represents 3%!
