Answer:
68 yards
Step-by-step explanation:
P=2l+2w (l=length, w=width)
318=2(91)+2w
318-182=2w
2w=136
width=68yds
Answer:

Step-by-step explanation:
The total number of digits required in numbering the pages of a book, which has 1,724 pages are 5,789.
Step-by-step explanation:
The total pages = 1,724
Now, to find the total digits, lets break down the pages.
1,724 is made up of
- 9 one digit numbers (1-9) = 9 x 1 = 9 digits
- 90 two digit numbers (10-99) = 90 x 2 = 180 digits
- 900 three digit numbers (100-999) = 900 x 3 = 2700 digits
- 725 four digit numbers (1000-1724) = 725 x 4 = 2900 digits
Now, lets add the digits.
9 + 180 + 2700 + 2900 = 5,789
Hence, the total number of digits required in numbering the pages of a book, which has 1,724 pages are 5,789.
Answer:

Step-by-step explanation:
2*12 ÷6 -1 +4
PEMDAS
Since there are no parentheses or exponents
Multiply and divide from left to right
24 ÷6 -1 +4
4 -1 +4
Then add and subtract from left to right
3+4

Answer:
(B)
Step-by-step explanation:
Let us denote rectangular tiles by R and square tile by S, then
According to figure.
3 rectangular tiles +2 square tiles +2 square tiles =2 rectangular tiles +4 square tiles +1 rectangular tiles +4 square tiles
∴3R+2S+2R=2R+4S+R+4S
⇒5R+2S=3R+8S
⇒5R-3R=8S-2S
⇒2R=6S
⇒R=3S
Hence, 0ne rectangle =3 square
