48 + 12 = t

60 years old

Step-by-step explanation:

Neither of these answer choices are correct...

If the tortoise was 48 years old when Sasha was born (when she was born she was 0 years old), now that she is 12, the tortoise will be 48 + 12 years old.

Since 48 + 12 is 60, the tortoise is now 60 years old.

Determine the sum: (14abc2 + 12a2b + 16b2c) + (−3abc2 + 2b2c).

Alenkinab [10]

The answer is 11abc^2 + 12a^2b + 18b^2c because:
14abc^2-3abc^2 is 11abc^2
12a^2b + 0 = 12a^2b
16b^2c +2b^2c = 18b^c

Mark made a scale drawing of a soccer field, using a scale of .5 cm=1m. The actual length of the field is 110 m. What is the len

nataly862011 [7]

Answer:

The length of the field on the drawing is 55 cm.

Step-by-step explanation:

Given:

Mark made a scale drawing of a soccer field.

Using a scale of .5 cm=1 m.

The actual length of the field is 110 m.

Now, to find the length of the field on drawing.

Let the length of the field on drawing be $x.$

As given 0.5 cm is equivalent to 1 m.

Thus, $x$ is equivalent to 110 m.

Now, to get the length of the field on drawing by using cross multiplication method:

$\frac{0.5}{1} =\frac{x}{110}$

<em>By cross multiplying we get:</em>

⇒ $55=x$

⇒ $x=55$

Therefore, the length of the field on the drawing is 55 cm.
