x = number of desks needed to make

equation:  150 +15.50x >= 400


solution:

150 +15.50x >=400

15.50x = 250

x = 250/15.50 = 16.129

he needs to assemble 17 desks

15.50*17 = 263.50 +150 = $413.50

Some kangaroos can cover 30 feet in a single jump if a kangaroo counts jump like that 150 times in a row how much farther wound
Svetradugi [14.3K]

Answer:

Distance farther the Kangaroos need to go to cover a mile = 780 feet

Step-by-step explanation:

Given:

Kangaroos cover 30 feet in a single jump.

Kangaroos can make such jumps 150 times in a row.

To find the distance farther it needs to go to cover a mile.

Solution:

Using unitary method to find distance covered by kangaroos in a row.

If in a single jump Kangaroos cover = 30 feet

So, in 150 jumps it will cover = 30\ ft \times 150 = 4500 feet

We know 1 mile = 5280 feet

Thus, distance farther the Kangaroo needs to go to cover a mile will be = 5280\ ft-4500\ ft = 780 feet

What is the area of this irregular figure?
Ahat [919]
The answer is 180mm^2. (B)

First, we can decompose the shape into a rectangle and a parallelogram. Let’s start with the rectangle.

Formula for a rectangle: bh

The base is 6 while the height is 12. You multiply like so. 6*12=72.

The area of the rectangle is 72.

The formula of a parallelogram is the same as the rectangle. (Bh)

To identify the base in this parallelogram, you would subtract the whole base length, 15 by half of the base length, 6.

15 - 6 = 9.

So the other half base length is 9.

You can simply transform a parallelogram into a rectangle by decomposing the parallelogram into two right triangles and a rectangle. You would take the right triangle at the bottom of the figure and move it to the top of the parallelogram in the photo. Thus, becoming a rectangle.

Now, we can identify the base and the height. The base of the parallelogram is 9 while the height is 12.

You would then multiply 9 by 12 like so to get 108.

After finding the area of the rectangle and parallelogram, you would add them up.

72 + 108 = 180mm^2

Therefore, making the answer choice B.
