Answer:

You decide that you will spend 2 times as many hours outdoors as you spend watching TV.

Let the hours spent outdoors be = o

Let the time spent on watching tv be = t

So, general equation becomes o=2to=2t

Last week, you watched 4 hours of TV. This week, you watched 8 hours of TV.

When t = 4

o = 2(4) = 8 hours

When t = 8

o = 2(8) = 16 hours

We have been asked to place points on the graph to show your activity for last week and this week.

Please find attached the points display.

19. Two angles are supplementary. The measure of one angle is four times the measure of the other angle. Find the measure of eac

Marysya12 [62]

36 and 144

Explanation

Two Angles are Supplementary when they add up to 180 degrees

Step 1

Let

x= angle 1

y= angle2

The measure of one angle is four times the measure of the other angle,then

$\begin{gathered} \text{angle}1=4\cdot\text{angle}2\text{ } \\ x=4y\text{ Equation(1)} \end{gathered}$

x and y are supplementary angles , then

$x+y=180\text{ Equation (2)}$

Step 2

use Equation (1) and (2) to find x and y

$\begin{gathered} x=4y \\ x+y=180 \end{gathered}$

replace Equation (1) in Equation (2)

$\begin{gathered} 4y+y=180 \\ 5y=180 \\ y=\frac{180}{5} \\ y=36 \end{gathered}$

replace the value of y= 36 in equation (1) to find x

$\begin{gathered} x=4y \\ x=4\cdot36 \\ x=144 \end{gathered}$

Hence, the answer is 36 and 144

Compute: √(14 - 2√13) * √(14 + 2√13) PLEASE HELP ME ASAP!!! Thank you!!!

Viktor [21]

Answer:

Step-by-step explanation:

√(14 - 2√13) * √(14 + 2√13) =
√(14 - 2√13)(14 + 2√13) =
√(14² - (2√13)²) =
√(196 - 4(13)) =
√(196 - 52) =

Cant find the answer

Answer:

Carter family = 25 hours

Davis family = 31 hours

Step-by-step explanation:

Let's say the number of hours the Carter family used their sprinkler is x and the number of hours the Davis family used their sprinkler for is y.

So combined:

x + y = 45 hours

and we are also told that:

40x + 15y = 1300 L

So we can do simultaneous equations to solve the problem.

With some rearranging, we can figure out that:

y= 45 - x

and by substituting that into the second equation:

40x + 15 (45 -x) = 40x + 675 - 15x = 1300L

25x = 1300 - 675

25x = 625

x = 25 = hours that the Carter family used their sprinkler

and we can substitute that back into the original equation to find how many hours the Davis family used their sprinkler so:

25 + y = 56

y = 31

The Davis family used their sprinkler for 31 hours whilst the Carter family used their sprinkler for 25 hours.
