If all the side on the square are 2.5 cm then you would multiply 2.5 times 4 (we get the four from the number of sides on the shape) and your answer is 10 cm
Answer:
30
Step-by-step explanation:
you cant make both 3, 10, or 13, so it has to be 30. 10x3=30
Answer:
it would take 40 pounds of pressure to break the board.
Step-by-step explanation:
![F = \frac{x}{L}](https://tex.z-dn.net/?f=F%20%3D%20%5Cfrac%7Bx%7D%7BL%7D)
Now we plug in the numbers of force and length
![24 =\frac{k}{2.5}](https://tex.z-dn.net/?f=24%20%3D%5Cfrac%7Bk%7D%7B2.5%7D)
Now we multiply both sides by 2.5 to get rid of the fraction.
![60=x](https://tex.z-dn.net/?f=60%3Dx)
Now we plug in our variation constant
![F=\frac{60}{L}](https://tex.z-dn.net/?f=F%3D%5Cfrac%7B60%7D%7BL%7D)
So we convert the length of 2.5 feet into inches. This is 18 inches. Since there are 12 inches in one foot, we have that 18 inches is equal to 18 divided by 12.
18÷12=1.5
We get that 18 inches is equal to 1.5 feet
we plug L = 1.5 into our inverse variation equation and solve for F.
![F=\frac{60}{1.5}](https://tex.z-dn.net/?f=F%3D%5Cfrac%7B60%7D%7B1.5%7D)
This simplifies to F = 40

Okay well ill do the first on and explain it so hopefully you can do the rest
3 and 1/3 is equal to 10/3 because a whole number would be 3/3 and we have 3 whole numbers plus 1/3
3/3
3/3
3/3
1/3
add it up and you get 10/3
Answer:
20
Step-by-step explanation:
First, let's find how much she spent on the expensive calculators
40 times $16400= $656,000
Now, lets find how much money she had for the cheap calculators.
$774,000- $656,000=$118000
Now that we have her budget (money remaining) for the cheaper calculators, lets divide that by the price for each individual calculator.
$118000/$5900=20
