The value of y varies directly with x and y = 4.5 when x = 0.5. find y when x = 10
Pepsi [2]
So what you asked this is what I got

x(y) = 4.5

If x= 0.5 then 

0.5(y) = 4.5
y=9

x(y) = 4.5

10(y) = 4.5
y= 0.45



hope this helps :)

Suppose the average temperature for a 4‐day period in Chicago, Illinois, is ‐8Ԭ. After the next day, the 5‐day average is ‐9Ԭ. W
exis [7]

Answer:

-13

Step-by-step explanation:

Given that:

Average temperature for a period of 4 days = - 8

Average temperature for a 5 day period = - 9

Temperature on the 5th day:

(total temp for the 4 days + 5th day temperature) / 5 = - 9

Let 5th day temperature = x

Total temperature for the 4 days = 4 * - 8 = - 32

(-32 + x) / 5 = - 9

-32 + x = - 45

x = - 45 + 32

x = - 13

A country's population in 1990 was 134 million. In 2000 it was 139 million. Estimate the population in 2014 using the exponentia
Rainbow [258]

Answer

P = 147 million

Step by step explanation

P = Po r^t -------------(1)

Po initial population, r = rate, t = number of years

Here P = 139, Po = 134, t = 10.

Now plug in these values into the formula and find the rate r.

139 = 134r^10

r^10 = 139/134

r = (139/134)^1/10

Now we got r, now plug in the equation (1)

Let's find the population in the year 2014, here t = 24

P = 134 (139/134)^(24/10)

P = 134(139/134)^(2.4)

P = 134*1.1

P = 147.4

P = 147 million

The country's population in 2014 is 147 million (estimation).

Thank you.
