Answer:
Step-by-step explanation:
Sorry, because of lack of punctuation and organization, I cannot determine with any confidence the price per kilo of each of the rices.
He will spend the price of one kg of African rice plus twice the price of Basmati rice.
IF
African rice = $1.69/kg
and
Basmati rice = $3.05/kg
THEN
Cost = 1.69 + 2(3.05) = $7.79
Answer:

Step-by-step explanation:
The exponential model for the population in t years after 2013 is given by:

In which P(0) is the population in 2013 and r is the growth rate.
In 2013, the moose population in a park was measured to be 5,100
This means that 
So

By 2018, the population was measured again to be 5,200.
2018 is 2018-2013 = 5 years after 2013.
So this means that
.
We use this to find r.







So the equation for the moose population is:

Answer:
$144
Step-by-step explanation:
divide 272 by 17 and then multiply that answer by 9
272/17 is 16
so 16 dollars an hour
multiply that by 9
you get 144
Answer:
y = 1/2x + 5
Step-by-step explanation:
Given :
Slope, m = 1/2
(x1, y1) = (6, 8)
y - y1 = m(x - x1)
y - 8 = 1/2(x - 6)
y - 8 = 1/2x - 3
y - 8 + 8 = 1/2x - 3 + 8
y = 1/2x + 5
Stamdard form of equation :
y = mx + c
Hence, equation is :
y = 1/2x + 5
