I think it is -28?????????
Answer:
Step-by-step explanation:
Below is the rectangle in the attachment.
Current scale:
1 cm : 6 inches
If the dimensions of the rectangle is:
Length = a cm
Width = b cm
Using the scale:
Length = a × 6 inches
Width = b × 6 inches
Using the same dimensions of the rectangle is:
Length = a cm
Width = b cm
Using the scale:
Length = a × 12 inches
Width = b × 12 inches
Note that there is an enlargement of the rectangle to form the new rectangle. The length and width of new rectangle drawn will be 2 × the length and width of the rectangle seen below.
Answer:
Three consecutive numbers are 27,28,29
Step-by-step explanation:
Given : The sum of three consecutive integers is 84.
To find : What are the integers?
Solution : Let three consecutive numbers ![x, x+1, x+2](https://tex.z-dn.net/?f=x%2C%20x%2B1%2C%20x%2B2)
So, according to given situation 'sum of three consecutive integers is 84'.
![x+x+1+x+2=84](https://tex.z-dn.net/?f=x%2Bx%2B1%2Bx%2B2%3D84)
![\Rightarrow 3x+3=84](https://tex.z-dn.net/?f=%5CRightarrow%203x%2B3%3D84)
![\Rightarrow 3x=84-3=81](https://tex.z-dn.net/?f=%5CRightarrow%203x%3D84-3%3D81)
![\Rightarrow x=\frac{81}{3}](https://tex.z-dn.net/?f=%5CRightarrow%20x%3D%5Cfrac%7B81%7D%7B3%7D)
![\Rightarrow x=27](https://tex.z-dn.net/?f=%5CRightarrow%20x%3D27)
So,![x=27](https://tex.z-dn.net/?f=x%3D27)
![x+1= 27+1=28](https://tex.z-dn.net/?f=x%2B1%3D%2027%2B1%3D28)
![x+2=27+2=29](https://tex.z-dn.net/?f=x%2B2%3D27%2B2%3D29)
Therefore, three consecutive numbers are 27,28,29
Answer:
25.100
Step-by-step explanation:
The thousandth place is the third digit to the right of the decimal point - tenths is the first, hundredths is the second, thousandths is the third. Since six rounds up and both nines round up, one must round up all of the way from the fourth decimal place to the tenth decimal place.
$40
40*90/100 = 36
You just have to be careful with the rest of the problem
