Answer:

The diver will use a total amount of 0.03 m³ in a minute

Step-by-step explanation:

Step 1: Determine number of breaths per minute

This can be expressed as;

Number of breaths=breaths per minute×number minutes

where;

breaths per minute=15

number of minutes=1

replacing;

Number of breaths=(15×1)=15 breaths

Step 2: Total volume of air used

This can be expressed as;

Total volume=volume per breath×number of breaths

where;

volume per breath=0.002 m3

number of breaths=15

replacing;

Total volume=(0.002×15)=0.03 m³

The diver will use a total amount of 0.03 m³ in a minute

Answer:

216 sq. units

Step-by-step explanation:

From the figure, we can see that only one pair of opposite angles are equal. So, the quadrilateral is a kite.

Formula to find the area of a kite:

Area, A = $ \frac{1}{2} \times d_1 \times d_2 $

where, $ d_1 $ and $ d_2 $ are the lengths of the diagonals.

Here, $d_1 = 18 $ units.

And, $ d_2 = 24 $ units.

Therefore, the area A = $ \frac{1}{2} \times 18 \times 24 $

= $ \frac{432}{2} $

= 216 sq. units which is the required answer.

Paul currently has $300 to spend on a data plan. He found a phone for $100 and a $50 a month charge.
zvonat [6]
Let x= months
So 50x is the total amount he pays after x months. You went to add 100 to this because there's a fixed cost of 100 for the phone
So you have the expression 100+50x which is the amount he pays after x months
Since he has a limit of 300,
100+50x < 300

Answer:

120 blocks total

Step-by-step explanation:

All of the little cubes have side length 2"  Thus, the 11" height of the box cannot be used entirely:  we waste the top 1" because the five layers of little cubes reach only to 10" from the bottom.

Start at the bottom of the box.  The dimensions of the bottom are 12" by 8".  Along the longer side we can lay 6 blocks (which add up to 12" and are 2" wide.  We can add 3 more such rows to fill the available 8" width of the box bottom.  That's 6*4, or 24 blocks.

We can add 4 more 6 block by 4 block layers before we have the maximum 5 layers stacked in the box.

5 layers times 24 blocks per layer comes to 120 blocks total.
