Given:
The base of the triangle = 8.6 yd
The height of the triangle = 10.9 yd
To find the area of the triangle.
Formula
The area of a triangle with b as base and h as height is
![A=\frac{1}{2}bh](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7Dbh)
Now,
Taking, b= 8.6 and h = 10.9 we get,
sq yd
or,
sq yd
Hence,
The area of the given triangle is 46.87 sq yd.
This an Arithmetic Progression question: (odd number: 1,3,5,7,...)
1st term a₁ = 1
the common difference is d=2
a term of rank n in a AP = a₁ + (n-1)d, where n = rank of the term.
Now let's apply the formula
a₈₇ = a₁ + (87-1).2
a₈₇ = 173
Answer:
the 3rd one. the rest are randomized.
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
P/5 + 6 = 10
P/5 = 10 - 6
P/5 = 4
(cross multiply)
P = 5 × 4
P = 20
Answer:
$14.40
Step-by-step explanation:
If you received 25% off then you paid 75% of the price. To find the original price, write a proportion.
![\frac{75}{100}=\frac{10.80}{y}](https://tex.z-dn.net/?f=%5Cfrac%7B75%7D%7B100%7D%3D%5Cfrac%7B10.80%7D%7By%7D)
Solve by cross multiplying.
75y = 1080
y = 14.4
