Answer:
let common difference be d.
a 18=a+17 d
a 14=a+13 d
a+17d - (a+13d) =32
a+17d - a - 13d =32
17d - 13d = 32
4d = 32
d=32/4
d=8
common difference=8
Step-by-step explanation:
(Brainliest if im correct?)
Square b area = 144 ÷ 2
area = 72 in squared
area in feet = 6 ft squared
Answer:
m<A = 120°
m<C = 45°
Step-by-step explanation:
We can use the triangle sum theorem to find the measures of the angles.
m<A + m<B + m<C = 180°
Then substitute in their given values.
12x + 12 + 15 + 3x + 18 = 180°
Now simplify the equation and you get
15x + 45 = 180°
Continue to solve
15x = 135
x = 9°
Now substitute this value of 9 for the angle expressions of <A and <C
(12 x 9) +12 = m<A
m<A = 120°
(3 x 9)+ 18 = m<C
m<C = 45°
Hope this helps. To check your answer you can add up all the answers to see if it equals 180°.
Answer: 13,864,675 seconds
Step-by-step explanation:
I minute 15 seconds = 75 seconds
That means it takes 75 seconds to achieve 150 , and it takes x seconds to achieve 27,729,350. Interpreting this in proportion form , we have:
150 ------ 75 seconds
27,729,350 ------- x seconds
Then
150x = 27,729,350 X 75
150x = 2,079,701,250
x = 2,079,701,250 / 150
x = 13,864,675
That means it takes 13,864,675 seconds to achieve the goal , converting this to minutes, we have:
231,077.9 minutes
