Calculate a rough estimate of the total lineal footage of lumber needed for a rectangular house 35’ x 40’?
Maru [420]

Answer:

B. 1,500’

Step-by-step explanation:

Given;

dimension of the rectangular house, = 35’ x 40’

The actual total linear footage of lumber needed = 35’ x 40’ = 1,400'

The rough estimate should be greater than the actual estimate in 100s;

rough estimate = 1,400' + 100' = 1,500'

Therefore, the rough estimate of the total linear footage of lumber needed is 1,500'.

Solve this inequality.<br><br> 8x + 6 less than or equel to 54
Step2247 [10]

Answer:

x\le 6

Step-by-step explanation:

We need to solve the given inequality 8x+6\le 54 ....(1)

Subtract 6 on both sides of the equation as :

8x+6-6\le 54-6\\\\8x\le 48

Dividing both sides of the equation by 8 such that,

x\le 6

So, the value of x is less than equal to 6. Hence, this is the required solution.

The total area of Canada is 9 984 670 km2. Calculate the side length of a square with the same area. Show your work.
Korolek [52]

Answer:

3159.853 km

Step-by-step explanation:

The question says a square has an area of 9,984,670 km^2, which means that all sides are the same length. So you can use the equation:

9984670 = (x)(x) which rearranges to 998470 = x^2

get the square root and you get:

x = 3159.853 km
