Answer:
5.78 * 10^8
Step-by-step explanation:
8.5 * 6.8 = 57.8
5+2=7
In scientific notation the number has to be greater than or equal to 1 and less than ten.
Answer: x = 19
Step-by-step explanation:
5(-12x+3) + 6(10x + 7) = 9 - x + 3x + 10 Distribute on the left side
-60x + 15 + 60x + 42 = 9 + 2x + 10 combine like terms on the left side
57 = 9 + 2x + 10 Now combine like terms on the right side
57 = 2x + 19 Subtract 19 from both sides
-19 -19
38 = 2x Divide both sides by 2
x = 19
11 is the answer to that question
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
18/6 = 3
So the temperature dropped 3 degrees each day.
Hope this Helps!!
