Answer:
1 /30
Step-by-step explanation:
25 marbles in total
P(B,B) = 5/25 x 4/24
= 1/5 x 1/6
Obtuse scalene, because none of the side are equal ( which would make none of the angles equal), but the one angle is over 90°
Square has 4 sides equal
garden has 4 sides of 50 each (4 times 50=200)
each smal garden is 10.5 times 4 sinc ethey also have 4 sides
10.5*4=42
times 3 since 3 of them
42*3=126
add to find total
garden+3rosebuds=200+126=326 ft^2
Matrix A order is 4x8.
Matrix B order is 4x16.
AB cannot result because an (m x n) can only be multiplied by an (n x p) matrix and orders don't match the requirements.
BA has the same negative result.
780, or C, is correct. Since 9.75 is 1/80th of the actual measurement, we can set up an equation like this:
9.75 = 1/80x
Then multiply each side by 80:
780 = x
The actual building's height is 780 ft.
We can check this answer by plugging in 780 for x in the original equation:
9.75 = 1/80(780)
9.75 = 9.75
