Answer:

#10= 264

#11= 13

Step-by-step explanation:

#10: We can see that this is a square because it says so in the question so we can assume that if it is a square then all the lengths and widths are 66 feet. 4(66) = 264 or 66+66+66+66 = 264

#11: 65/5 = 13 because it is dealing with area, simply just divide the total of area by the known length to get the width.

Answer:

10. 264

11. 13

Step-by-step explanation:

10- When we are doing perimeter we add all the sides together. Since it's a square this time, we know all the sides are even at 66ft.

66+66+66+66= 264

I added 4 times for each side we have and we get the perimeter of 264

11- When dealing with area, all we need is two numbers. To get area we multiply the length and width. If we have the area and want either length or width, we can still easily do that. All we have to do is divide the area from your given number.

65 divided by 5 is 13

Area divided by Length is Width

10+2r=8 need the answer now

natulia [17]

Simplifying

10 = 2r + -8

Reorder the terms:

10 = -8 + 2r

Solving

10 = -8 + 2r

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add '-2r' to each side of the equation.

10 + -2r = -8 + 2r + -2r

Combine like terms: 2r + -2r = 0

10 + -2r = -8 + 0

10 + -2r = -8

Add '-10' to each side of the equation.

10 + -10 + -2r = -8 + -10

Combine like terms: 10 + -10 = 0

0 + -2r = -8 + -10

-2r = -8 + -10

Combine like terms: -8 + -10 = -18

-2r = -18

Divide each side by '-2'.

r = 9

Simplifying

r = 9

This is due tomorrow, so please help and show step by step

Answer:

slope = 3/2
y-intercept = 3
x-intercept = -2

Step-by-step explanation:

The slope is the coefficient of x when the equation is of the form ...

y = (something).

Here, we can put the equation in that form by subtracting 12x and dividing by the coefficient of y:

12x -8y = -24 . . . . . given

-8y = -12x -24 . . . . .subtract 12x

y = 3/2x +3 . . . . . . . divide by -8

This is the "slope-intercept" form of the equation. Generically, it is written ...

y = mx + b . . . . . . where m is the slope and b is the y-intercept

So, the above equation answers two of your questions:

slope = 3/2

y-intercept = 3

The x-intercept is found fairly easily from the original equation by setting y=0:

12x = -24

x = -24/12 = -2 . . . . . the x-intercept

_____

A graph of the equation can also show you these things. The graph shows a rise of 3 units for a run of 2, so the slope is rise/run = 3/2. The line crosses the axes at x=-2 and y=3, the intercepts.

the function p(t)p(t)p, left parenthesis, t, right parenthesis models the average high temperature, in degrees celsius, of paity

Mnenie [13.5K]

The solution set for the last equation represents the set of all days when the towns have the same average high temperature.

The hotness of matter or radiation is expressed by the physical quantity known as temperature. The average air temperature for a specific time period, often a day, a month, or a year, as measured by a thermometer that has been properly exposed.
P(t) is the average high temperature, in degrees Celsius, of Paityn's town on t days.

$\begin{aligned} P(t)&=22.5+7.5\cos\left(\dfrac{2\pi (t-28)}{365}\right)\\\\ \end{aligned}$
