Phoenix [80]

Answer:

26. D) $252

27. A) -6.7 + 6.8

Step-by-step explanation:

26. 400 * 0.3 = 120

400 - 120 = 280

280 * 0.1 = 28 (because the 10% is additional, cannot add it to the original 30%)

280 - 28 = 252

27. -4.5 + 4.4 = -0.1

- 6.7 + 6.8 = 0.1

-0.1 + 0.1 = 0

ANSWER

Area = 2\sqrt{3}  \:  {cm}^{2}

EXPLANATION

We need to use the Pythagoras Theorem to find the height of the triangle.

{a}^{2}  +  {b}^{2}  =  {c}^{2}

({2 \sqrt{3}) }^{2}  +  {b}^{2}  =  {4}^{2}

12 +  {b}^{2}  = 16

{b}^{2}  = 16 - 12

{b}^{2}  = 4

Take positive square root to get;

b =  \sqrt{4}  = 2

Area =½bh

Area =  \frac{1}{2}  \times  2\sqrt{3}  \times 2

Area = 2\sqrt{3}  \:  {cm}^{2}
