I think C is the correct awnser
Answer:
384 Cubic Inches
Step-by-step explanation:
We can divide the original object into two separate shapes, then we can take the first shape of 6*4*2, and find its volume of 48, then we can take the larger object of 12 * 14 * 2 and find its volume of 336 and add the two values together to find the original shape's volume of 384 Cubic Inches.
Answer:
Step-by-step explanation:
in complementary angle, the sum of two angle is always 90 degree.
let another angle be x
x+78.7=90
x=90-78.7
x=11.3
therefore anothere angle is 11.3 degree.
A19 = -92
a20 = 6
common difference = d = a20 - a19
d = 6 - (-92)
d = 6 + 92
d = 98
formula for nth term
an = a1 + (n-1)d
put n = 20
a20 = a1 + (20-1)d
6 = a1 + 19(98)
6 = a1 + 1862
6 - 1862 = a1
-1856 = a1
a1 = -1856
now nth term:
an = a1 + (n-1)d
an = -1856 + (n-1)98
an = -1856 + 98(n-1)
