Answer:
area = 50 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 
h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here h = 4, a = 15 and b = 10, thus
A = × 4 × (15 + 10) = 2 × 25 = 50 cm²
Answer:
0.125
Step-by-step explanation:
1/2 divided by 4 equals 0.125
Answer:
3x+4y=-11
Step-by-step explanation:
Answer:
-613/716.
Step-by-step explanation:
The reciprocal of a number is basically that number upside down. to find the reciprocal of a whole number, you can just turn the number into a fraction, and put one as the numerator, and the original number as the denominator. given this information we know that the reciprocal of -716 is -1/716, so now yoj can simply cross multiply 613 by -1/716, which gives you -613/716.
The union of the two sets is the combining of the two sets, so the correct answer is A. {4, 8, 10, 12, 14}.
Hope this helps =)
