I can't really tell if the question is asking about 7 or -7, so I'll give the answer for both.
A multiplicative inverse for 7 is a number you can multiply by 7 to make it equal to 1. In terms of an equation, you would get 7x = 1. We can then solve for x by dividing both sides by 7. So x = 1/7.
For -7, you would be able to solve the same equation as above just with -7 in the place of 7. You would end up with x = -1/7.

Answer:
B. 1,486 metres
Step-by-step explanation:
Find the area of the triangle.
60 x 60 = 3600
3600 ÷ 2 = 1800
Area of triangle = 1800 metres
Area of unshaded circle is approximately 314 metres square using pi
1800 - 314 = 1486
1486 metres square is the approximate area of the shaded region.
Answer:
The answer is below
Step-by-step explanation:
Natalee transferred water from a square pyramid to a cube. To calculate how many times she will need to dump the water from the pyramid into the cube to completely fill the cube, we divide the volume of the cube by the volume of the square pyramid. Hence:
Number of times = volume of cube / volume of pyramid
The perimeter of the pyramid base = 25 in, hence the length of one side of the bae = 25 / 4 = 6.25 in
Volume of square pyramid = base² × (height / 3) = (6.25 in)² * (5 in / 3) = 65.1 in³
Volume of cube = 125 in³
Number of times = 125 in³ / 65.1 in³ = 1.92
