Answer:

Step-by-step explanation:

Decompose each number:

$6) 90 = 9 \times 10\\\\7) 40 = 4 \times 10\\\\8)890 = 89 \times 10\\\\9) 300 = 3 \times 100\\\\10) 7000 = 7 \times 1000\\\\11)3700 = 37 \times 100\\\\$

Correct the error. Write the correct decomposition:

$12) 560 = 56 \times 10\\\\13) 4300 = 43 \times 100\\\\14) 6000 = 60 \times 100 \ \ or \ \ 6 \times 1000$

kap26 [50]

Answer:

h = b(√3)/2

Step-by-step explanation:

The ratio of base to height of an equilateral triangle is ...

... b/h = 2/√3

Multiplying both sides of the equation by (√3)h/2, we get

.. h = b(√3)/2 . . . . . . your equation with h as the subject

Vlada [557]

Answer:

x>10
