If he ran 1/2 hr each morning, then he ran 1 hr every 2 mornings
60/2 = 30...so he ran a total of 30 hrs in 60 days
and if he averages 6.5 miles per hr....then the total miles that he ran in 60 days is (6.5 * 30) = 195 miles

Find his average for each day and multiply by 60.

So, 6.5/2 (Since he ran 6.5 in an hour and half an hour each day- one hour would be two days.)
6.5/2= 3.25

So his total miles would be 60 times his average 3.25.

60 x 3.25 = 195miles

jarptica [38.1K]

Answer:

a) The average global surface temperature in 2100 is 10.7°C

b) b) The slope of the function, 0.01, represents the rate of yearly increase of average surface temperature on the planet and the intercept represents the average surface temperature on the planet in 1900 (the reference year that the average surface temperature for subsequent years are calculated with respect to).

Step-by-step explanation:

T = 0.01t + 8.7

To predict the temperature of the planet in the year 2100.

We will calculate the number of years that 2100 is, since 1900

t = 2100 - 1900 = 200 years

T = (0.01 × 200) + 8.7 = 10.7°C

The average global surface temperature in 2100 is 10.7°C

b) The slope of the function, 0.01, represents the rate of yearly increase of average surface temperature on the planet and the intercept represents the average surface temperature on the planet in 1900 (the reference year that the average surface temperature for subsequent years are calculated with respect to).

Step-by-step explanation: Is (5, 5) a solution to the equation y=x ?
enyata [817]

Answer:

Yes, (5,5) is a solution of y=x

Step-by-step explanation:

A point is given as a coordinate pair, (x,y). The first number is x and the second number is y. A solution is a pair of numbers that will make the equation true.

To check if the point is a solution, fill in the first number in place of x in the equation. Then fill in the second number for the y.

Here we have the equation:

y = x

Substituting (filling in) we get:

5 = 5 a true statement. So (5,5) IS a solution.

Alternatively, you could graph the equation and verify that the point is on the graph. see image.

Bezzdna [24]

Answer:

19 units

Step-by-step explanation:

use distance formula: d = \sqrt{(x_2-x_1)^{2}+(y_2+y_1)^{2}}

x₂ = 10

x₁ = -1

y₂ = 6

y₁ = 6

now plug in

\sqrt{(10-(-9))^{2}+(6-6)^{2}}\\= \sqrt{19^{2}+0^{2}\\}\\= \sqrt{361}\\= 19
