Svetach [21]

Answer:

See below

Step-by-step explanation:

Number of squares:

1x1 squares = 8*8
2x2 squares = 7*7
3x3 squares = 6*6
4x4 squares = 5*5
5x5 squares = 4*4
6x6 squares = 3*3
7x7 squares = 2*2
8x8 square = 1

Total number:

8² + 7² + 6² + 5² + 4² + 3² + 2² + 1 =
64 + 49 + 36 + 25 + 16 + 9 + 4 + 1 =

The distance traveled (d) varies directly as the time (t) of

Helen [10]

Answer:

2.70 hours to travel 180 mi.

Step-by-step explanation:

The distance traveled (d) varies directly as the time (t) of travel, by the following formula:

$s = \frac{d}{t}$

In which s is the velocity.

It takes 63 min to travel 70 mi.

So i am going to find the velocity in miles per minute

$s = \frac{70}{63} = 1.11$

how many hours would it take to travel 180 mi?

I am first going to find the time in minutes, then divide by 60 to pass to hours.

$s = \frac{d}{t}$

$st = d$

$t = \frac{d}{s}$

$t = \frac{180}{1.11}$

$t = 162.16$

It takes 162.16 minutes = 162.16/60 = 2.70 hours to travel 180 mi.

Husky Shipping Company charges a flat rate of $150 plus $0.60 per pound to transport freight in the metro area. This cost is rep

Alex73 [517]

Answer:

Total cost = $1,050

Total cost = Fixed charges + Variable charges[Total weight]

Step-by-step explanation:

Given:

Fixed charges = $150

Variable charges = $0.60

Total weight = 1,500 pound

Find:

Total cost

Computation:

Total cost = Fixed charges + Variable charges[Total weight]

Total cost = 150 + 0.60[1,500]

Total cost = 150 + 900

Total cost = $1,050

a crane lifts a pallet of concrete blocks 7 ft from the back of the truck . the truck driver away and the crane lowers the palle

n200080 [17]

Answer:

4 ft down as per the image attached.

5 ft down as per the question statement.

Step-by-step explanation:

Given that:

A Pallet of concrete blocks is at the back of a truck.

The pallet is lifted by the crane to a height of 8 ft (as per image attached ) or 7 ft (as per question statement) and then the truck moves forward.

Now, the pallet is lowered down to a distance of 12 ft.

To find:

The final position of the pallet relative to the position from the back of the truck?

Solution:

If we closely look at the figure attached, it can be interpreted that the pallet is taken 8 feet above and then 12 feet down.

Therefore, if we subtract 8 feet from 12 feet, we will have our answer.

So, the position of the pallet with respect to its position in the truck is =

12 ft - 8 ft = 4 ft down.

If we consider the question statement:

12 ft - 7 ft = 5 ft down
