Answer:
v = 87
Step-by-step explanation:
the angle v+39 lies on a straight line. so substract v+39 from 180 to get the interior angle for that side.
afterwards, knowing that the sum of interior angles of a triangle = 180, form an equation with all the angles and solve for v
Answer:y= - Squared x squared + z squared
Step-by-step explanation:
1 modulo 9 is the set of numbers as follows:
(0(9) + 1), (1(9) + 1, ....)
which is:
1, 10, 19
All we have to do is divide 1000 by 9, and round down.
1000/9 = 111.111......
There are 111 numbers.
Now let us check our work.
the set is as follows:
(1,10,19, ....... (111)9 +1)
(1, 10, 19 ........ 1000)
We are within 1000.
Therefore, 111 of the 1000 smallest positive integers are congruent to 1 modulo 9.
3/4 is great if thats on of your answers because it was one of mine
Answer:
$3,075
Step-by-step explanation:
Given, for a triangular sail (assuming its a right triangle)
base dimension = 15 feet
height = 20 feet
Area of sail,
= area of right triangle
= 1/2 x base x height
= 1/2 x 15 x 20
= 150 ft²
we are given that the price per squre foot is $20.50
hence cost of sail
= price per square foot x area of sail
= $20.50 x 150 ft²
= $3,075
