Answer:
Step-by-step explanation:
this is exactly the same as the 1st one, just they put it in a different orientation. sooo use law of cosines , where
QR = c
a = 12
b = 23
cos(120) = cos (P)
c = sq rt [ a^2+b^2﹣2*a*b*cos(P) ]
QR = sq rt [ 12^2 + 23^2 - 2* 12*23*cos(120) ]
QR = sq rt [ 144 + 529 - 552 * (-0.5 0 ]
QR = sq rt [ 673 + 276 ]
QR = sq rt [ 949 ]
QR = 30.8058
rounded to nearest 10th is
QR = 30.8 :)
81^5 = 3,486,784,401
3,486,784,401 / = X
X = 1,162,261,467
(I think anyways)
The company would charge $837.50 to build the fence.
Installing a fence would cost $62.50 per hour.
It will take 13²/₅ hours to install this fence.
The cost would be:
<em>= Cost per hour x Number of hours taken </em>
Number of hours it would take should be converted to improper fraction to be multiplied:
13²/₅ = 67/5 hours
Cost is:
= 62.50 x 67/5
= $837.50
In conclusion, it would cost $837.50 to build the fence.

Answer:
The required equation is 3y=36 and the tape diagram is shown below.
Step-by-step explanation:
Consider the provided information.
We need to write a multiplication equation that has a solution of 12.
3y=36
We know we have to split 36 into three equal groups, so we have to divide by 3 to show this algebraically.
3y÷3=36÷3
y=12
Now check this with the help of tape diagram as shown.
Consider the figure 1.
This represents if 36 had to be split into three groups, how big would each group be?
By the tape diagram we concluded that the value of y is 12.
Answer:
x^3 +x^2 +x+1
