Total weight = 50 lb
x = number of 3-lb weights
y = number of 10-lb weights

weight of 3-lb weights = 3x
weight of 10-lb weights = 10y
total weight = 3x + 10y

equation
3x + 10y = 50

If 12 cows produce 70 gallons of milk, how many gallons of milk would 42 cows produce?
I am Lyosha [343]
This is a proportions question
  12        42
------  =  -------
  70          ?

Cross multiply

70x42=2940
12x?=2940
294/12=245

42 cows can produce 245 gallons of milk.
So the answer is B.

Hope I helped!

Answer:

Slope (m) = \frac{y}{x} = \frac{3}{1} =3

Step-by-step explanation:

Slope (m) = \frac{y}{x} = \frac{3}{1} =3

0 = arctan(\frac{y}{x}) + 180^o = 251.56505117708^o

X = -4 – -2 = -2

Y = 4 – 10 = -6

Distance (d) = \sqrt{x^2+y^2}=\sqrt{40} = 6.3245553203368

Equation of the line:

y = 3x + 16

When x=0, y = 16

When y=0, x = -5.3333333333333

liraira [26]

Answer:

The population in 2003 was 234  million

Step-by-step explanation:

In order to calculate the population in 2003 we would have to use the The exponential growth formula as follows:

p(y)=ir^t

According to the given data:

p(y)=233 million

i=231 million

t =1999-1991

Therefore, 233 million=231 million r^(1999-1991)

(233 million/231 million)^(1/8)=r

p(y)=231 million(233 million/231 million)^((y-1991)/8)  

Therefore, in 2003   p(2003)=231 million(233 million/231 million)^((2003-1991)/8)

p(2003)=231 million(233 million/231 million)^(1.5)

p(2003)=234  million

The population in 2003 was 234  million
