Answer: 50.24 cm^2
Step-by-step explanation:
This can be translated to:
An old coin is kept in a cubic box in such a way that the outline of the coin touches the 4 walls of the box, if the base of the box has a perimeter of 24 cm. What is the area of the coin?
The fact that the coin touches the interior of the box means that the diameter of the coin is equal to the side lenght of the box.
The perimeter of the box is 24 cm, and the perimeter of a square is equal to:
P = 4*L
where L is the side lenght of the square.
24 cm = 4*L
L = 24cm/4 = 8cm
Now we know that the diameter of the coin is 8cm
Now, the area of a circle (the coin) is equal to:
A = 3.14*(d/2)^2
where d is the diameter, so we have:
A = 3.14*(4cm)^2 = 50.24 cm^2
If we assume the student’s sample is representative of the whole population, then yes, the student can be considered accurate.
7 / 50 = 0.14
400 * 0.14 = 56
About 56 of the 400 students can be estimated to have traveled outside the US.
Answer:
The corresponding side in the smaller figure is 9 cm
Step-by-step explanation:
Notice that you can use proportions to solve this problem:
The ratio from large image to smaller is: Larger/smaller = 4/3.
Therefore use this type of proportions to find the length of the corresponding side to 12 cm in the smaller figure:

I don’t think I can see your picture clearly- can you take it again? ❤️
Answer:
no solution
Step-by-step explanation:
ya gotta use your eyes and brain huney. it aint that hard. kk? but ill still explain for you.
since x+y=6 and x+y=4. then 4=6. but that is false so no solution.
YOUR WELCOME!
