Compute using significant digits. What is the area of a parallelogram with length 17.25 mm and width 5.065 mm?

Dmitriy789 [7]

Answer: Option 'a' is correct

Step-by-step explanation:

Since we have given that

Length of parallelogram =17.25 mm

Width of parallelogram =5.065 mm

As we know the formula for " Area of parallelogram"

Area of parallelogram is given by

$Area= length \times breadth\\\\17.25\times 5.065=87.03 \ mm^2$

Hence, option 'a' is correct .

Earl wants to earn enough money to purchase a bike that costs $515. For every lawn he mows he earns $25 and then gets a daily bo

inysia [295]

Answer:

18 lawns

Step-by-step explanation:

Expected sum = $515

Bonus for 1 day = $15

Bonus for 5 days = $15 × 5 = $75

Amount to be earned from mowing lawns in 5 days = $515 - $75 = $440

$25 ≡ 1 lawn

$440 ≡ 440 ÷ 25 = 17.6

The minimum number of lawns is 18.

(Note that we take the minimum integer greater than 17.6. If he mows 17 lawns, his earning from 17 lawns = $425 + $75 = $500)
