Answer:
625 unit²
Step-by-step explanation:
Surface area of a rectangular pyramid :
Area of base * 4(area of triangular side)
Area of base = length * width
Area of base = 15 * 15 = 225
Height of triangular side = 15
Area of triangle = 1/2 * base * height
Area of triangle = 1/2 *15 * 15 = 112.5 unit²
Surface area = 225 + 4(112.5)
Surface Area = 225 + 450
Surface Area = 625 unit²
Answer:
$118,791.2985
Step-by-step explanation:
Given that,
A = 160,000
T = 18 - 8 = 10 years
Rate = 3%
since it is semi annual, n = 2
A = P ( 1 + R/2) ∧ 2T
160000 = P ( 1 + 3/2*100) ∧ 2 * 10
160000 = P ( 1 + 3/200) ∧20
160000 = P( 1 + 0.015) ∧20
160000 = P(1.015)∧20
P= 160000/ (1.015)∧20
P = 160000/ 1.3469
= $118,791.2985
He still has to collect 30 coins
(2,000-1951=49, but he needs the coin from 1951 as well so it is equivalent to 50)
50 x .4=20
50-20=30
I believe it’s 2/1 and the slope is 2 since it crosses the y-int at 2.
Answer:
1/151200
Step-by-step explanation:
The number of ways to pick an exact order of any 6 different numbers from 10
=
= 10×9×8×7×6×5 = 151200 ways
which means the first one can be any of 10 numbers
The second one can be any of 9 numbers
The 3rd one can be any of 8 numbers and so on
Now the 6th one can be any of 5 numbers
Thus there are 10×9×8×7×6×5 = 151200 ways to choose the number
so the required probability is 1/151200
