Answer: it's impossible to obtain 78
Step-by-step explanation: Since the calculator can double any number or permute its digits except 0
starting with number 1
1, 2, 4, 8, 16, 32, 64, 128
Therefore, it's impossible to obtain 78 by a series of these operations
Answer:
97 meters
Step-by-step explanation:
The area of a rectangle is its length multiplied by its width. Substitute the known values into this equation and solve for the length, l:
a = lw
8342 = 86l
l = 97
Answer:
6.3 ft.
Step-by-step explanation:
This requires the pythagorean theorem: a^2+b^2=c^2 where "a" and "b" are legs and c is the hypotenuse(longest side of the triangle which is opposite to the 90 degree angle.) If we fill the equation where c is the ladder length(11) and "a" is the distance from the house(), and "b" is the height, 9^2+b^2=11^2 or 81+b^2=121. This is equivalent to b^2=40. b=6.3 when rounded to the nearest tenth.
Answer:
Hello!!
the point (6, 7) is reflected across the y axis. what are the coordinates of the reflection?
(-6, 7)
Step by Step Explanation:
When reflecting (x, y) over the x axis is (x, -y)
When reflecting (x, y) over the y axis is (-x, y)
Hope this helps!
