The answer depends on the way you solved it.

I am assuming you take the base on which you perceived to be: . 5 and height which is 2.


So you must've ended with 1

But in actuality, you need to use the equation above and plug in 1.5 and 1
Subtract them and you should get 1.25

Do the same to the other side, you should get 6.

.125 x 6  = .875

The length of the base of the rectangle is 1.5-1=0.5

We need to find the height. The height is equal to y-value of the point that lies in the corner of the rectangle and also on the graph of the function. We put the x-value of that point into the function. So ,the height is equal to 4-1.5^2=1.75

Therefore, the area of the rectangle is 0.5\cdot1.75=0.875

Answer:

2109 meter squared

Step-by-step explanation:

Area  \: of \:  path  \\ = (400+3)(300+3)-400 \times 300 \\  = 403 \times 303 - 120000 \\  = 122,109 - 120000 \\  = 2109 \:  {m}^{2}

SAM now has 30ml of pop to share equally into glasses.
crimeas [40]
So whole ml's


30 mls
find what 30 is evenly divisble by
factor 30
30=2 times 3 times 5
therefor
30 is divisble by 2,3,5,6,10,15

so he can divide the glass into 2 sevings which is 30/2=15 ml in each

servings    ml         fraction
2              15            15/30=1/2
3              10              10/30=1/3
5                6             6/30=1/5
6              5                5/30=1/6
10               3              3/30=1/10
15              2              2/30=1/15

Please help me. (20 points)

Hello from MrBillDoesMath!

Answer:

75

Discussion:


A plane triangle has 180 degrees. Using this in the diagram gives  

x + 81 + angle BAC = 180             (***)

(The diagram is a bit fuzzy but I think the above numbers are accurate)

The diagram also shows that  (156 + angle BAC )= 180 as a straight line has 180 degrees. So

angle BAC = 180 - 156 = 24

Substituting this in (***) above gives

x + 81 + 24 = 180 =>

x + 105 = 180   =>               (as 81 + 24 = 105)

x = 180  107 = 75


Check: Does

x + 81 + angle BAC = 180   ?

75 + 81 + 24 = 180.  Yes




Thank you,

MrB

Lines m and p are perpendicular. If the slope of line m is -3, what is the slope of line p?​
nika2105 [10]

Answer:      The slope of p is 1/3

Step-by-step explanation:    

If the lines are perpendicular, this means they are opposite.

Thus, O is opposite P and since O = -3, P = 1/3
