Answer:
1.Three and Nine Hundredths 2. 3 9/100 3. 390%
Step-by-step explanation:
Step-by-step explanation:
To fond the area of a trapezoid, add the top and bottom together, divide that by 2, than multiply by the height.
Area = (8+12)/2 = 20/2 = 10
10 x 9 = 90 square centimeters.
Answer:
(14a+3, 21+4) = 1
Step-by-step explanation:
We are going to use the Euclidean Algorithm to prove that these two integers have a gcd of 1.
gcd (14a + 3, 21a + 4) = gcd (14a+3, 7a + 1) = gcd (1, 7a+1) = 1
Therefore,
(14a + 3, 21a + 4) = 1
Answer:
Answer is A. 30 degree
as we know that two prependicular lines have 90 degree angle between them
and similarly a horizontal line has angle zero degree.
the angle of pic shown is approximately 30 degree as it lies between prependicular and horizontal nature of lines
but as we can see that it is close to horizontal nature of the line that's why its approximate angle is 30 degree.
