Part C<br> How many cubic blocks are needed to fill the fish tank?

nikklg [1K]

Answer:

$2\frac{2}{3}$ cubic blocks

Step-by-step explanation:

The given parameters are:

$Length = \frac{1}{2}yd$

$Width = 16yd$

$Height =\frac{1}{3}yd$

Required

Number of cubic blocks to fill the tank

To do this, we simply calculate the volume of the tank by:

$Volume = Length * Width * Height$

This gives:

$Volume = \frac{1}{2} * 16 * \frac{1}{3}$

$Volume = \frac{16}{6}$

Simplify

$Volume = \frac{8}{3}$

Express as mixed numbers

$Volume = 2\frac{2}{3}yd^3$

Please help I don’t understand it’s like angles and stuff picture above.

dusya [7]

Answer:

1) 145°

2) 20°

3) x = 7 ; measurement of the missing angle = 24

Step-by-step explanation:

1) supplement = 180°, 180 - 35 = 145

2) complment = 90° , 90 - 70 = 20

3) the figure is a right angle so the measurement is 90°

66 + (4x-4) = 90

62 + 4x = 90

4x = 28

x = 7

4(7) - 4

28 - 4

= 24

Answer:

$\displaystyle 40\:mm.^2 = A \\ 32\:mm. = P$

Step-by-step explanation:

All vertices meet at right angles, so sealing off these two rectangles will give you this:

$\displaystyle [2][4] + [4][8] = 8 + 32 = 40; 40mm.^2 \\ 4 + 6 + 2 + 4 + 8 + 8 = 32; 32mm.$

* The missing sides are 4 and 6.
