Here's the work:
Density = mass/volume = 129g/(5*3*2) cm^3 = 4.3 g/cm^3.
Answer:
Well -7>-7.5
Step-by-step explanation:
Negative numbers are that the Humber that is closest to 0 is the greatest. Like in -7 and -7.5, the -7 is closer to 0 so its greater.
All sides of a cube are the same.
So to calculate the volume, you only need to know the measure of one side.
The formula for the volume of a cube is the length of the edge to the power of 3.
The measure of the known edge is 9, so the formula for volume would be 9^3.
9^3 is 9 • 9 • 9, which is 9 times 9 times 9.
9 • 9 = 81
81 • 9 = 729
The volume of this cube is 729 cubic feet.
There must be a typo in the answer choices because 729 cubic feet is the answer for the volume of the cube, even though it's not listed.
A = 4. B = 1. The b’s cancel each other out. Then you have 2a = 8. Divide 8 by 2 and get 4. That’s a=4. Then put a back into either problem. So 4+_=5. B=1. 16-1=15. 15 is the answer
Answer:
0.2391 = 23.91% probability that the student is between 26 and 35 inclusive.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, we have that:
409 + 409 + 204 + 60 + 22 = 1104 students, in total
204 + 60 = 264 between 26 and 35.
264/1104 = 0.2391
0.2391 = 23.91% probability that the student is between 26 and 35 inclusive.
