Answer:
129.5 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A =
h(a + b)
where h is the height and a, b the parallel bases
Here h = 7, a = 15 and b = 22 , thus
A =
× 7 × (15 + 22)
= 0.5 × 7 × 37
= 129.5
4 10/8 breaks down to 5 2/8 = 5 1/4
3 1/2 + 1 3/4
3 1/2 = 3 2/4
3 2/4 + 1 3/4 = 4 5/4
the correct answer is 5 1/4
so yes, your answer IS correct!
Reciprocal is basically just swapping them around, so for 10/3 it's 3/10 and that's your answer!
EQUI = equals
VALent, as in value related
EQUI + VALent, same value
Answer:
3,943.84
Step-by-step explanation:
Since we know the angle of the arc is 70°, its length will be 7/36 of the whole circumference. The circumference, which is 2*pi*r, is 20 pi = 62.8, so the arc JL is 7/36 * 62.8 = 3,943.84
