Step-by-step explanation:
A=s*s
A=s^2
52=s^2
s=√52
s=7.2 one side of the square
s*4 to get the four sides
7.2*4=28.8 cm length of the first piece
40-28.8=11.2cm length of the second piece
1.25 pounds (sorry i had to use more characters)
To find the percentage of a number multiply it by whatever decimal you are using or a fraction that you have to convert into a decimal to find the percent. Example: What is 10% of 25? (.10)(25) = 2.5 so 10% of 25 is 2.5.
Answer:
To find the result of 300 - 650, we can:
a) do 650 + 300 and keep the result sign
b) do 650 + 300 and invert the result sign
c) do 650 - 300 and keep the result sign
d ) perform 650 - 300 and invert the result sign
Step-by-step explanation:
The correct answer is the letter D .
(perform 650 - 300 and invert the result sign)
300 - 650
300 is more than - 650 on the number line this is because of the negative sign of 650
so we can also write it as 650 - 300 and after getting the require result with put the negative sign to the result, so the result will be -350
Keep the sign of the number with the highest absolute value and subtract from it the lowest absolute value.
- (650 - 300)
Subtract the numbers.
- 350
therefore, the answer is d ) perform 650 - 300 and invert the result sign
32 because you divide 40 bye 5 which is 8 then you times 8 bye 4
