C I think I hope this is correct
Area of rectangle = l × b
l = 70cm
b = 8cm
Area = 70 × 8 = 560cm²
Area of rectangle = l × b
l = 78cm
b = 15cm
Area = 78 × 75 = 1170cm²
Answer:
$91.67.
Step-by-step explanation:
We have been given that Mark is creating a tarp to cover his new vegetable garden outside. He needs enough nylon to cover the garden which is 10 feet by 8 feet and then he will attach rope along the edges of the nylon to stake it down with.
A. Let us find area covered by nylon by multiplying 10 by 8.
Now let us convert area of needed nylon from square feet into square yard by multiplying 80 by 0.111111.
Now let us multiply 8.88889 by 5.25 to find the cost of nylon cover of the garden.
Therefore, the cost of nylon cover will be $46.67.
B. Now let us find length of rope by finding the perimeter of the garden.
Now let us find the cost of 36 feet long rope by multiplying 36 by 1.25.
Therefore, the cost of rope will be $45.
To find the total cost to make the cover we will add cost of nylon cover and cost of rope.
Therefore, it will cost $91.67 for Mark to make the cover for vegetable garden.

Answer:
x ≈ 4.2
Step-by-step explanation:
The relevant trig relation is ...
Tan = Opposite/Adjacent
tan(72°) = b/x = 13/x
x = 13/tan(72°) ≈ 4.223956
Rounded to the nearest tenth, x ≈ 4.2.
If the pth term of an arithmetic progression is q and qth term is p then the (p+q) th term is 0.
Given that the p th term of an A.P is q aand q th term is p.
We are required to find the (p+q) th term of that A.P.
Arithmetic progression is a sequence in which all the terms have common difference between them.
N th term of an A.P.=a+(n-1)d
p th term=a+(p-1)d
q=a+(p-1)d-------1
q th term=a+(q-1)d
p=a+(q-1)d---------2
Subtract equation 2 by 1.
q-p==a+(p-1)d-a-(q-1)d
q-p=pd-qd-d+d
q-p=d(p-q)
d=(p-q)/(q-p)
d=-(p-q)/(p-q)
d=-1
Put the value of d in 1.
q=a+(p-1)(-1)
q=a-p+1
a=q+p-1
(p+q) th term=a+(n-1)d
=q+p-1+(p+q-1)(-1)
=q+p-1-p-q+1
=0
Hence if the pth term of an A.P is q and qth term is p then the (p+q) th term is 0.
