Answer
Answer:
40 degrees
Step-by-step explanation:
We know the entire angle of ABD is 70 and CBD and ABC are in it.
Since we know one of them (CBD) is 30, we can subtract 30 from 70 to find ABC. This is because the angle of ABC and CBD equal ABD.
30 + x = 70
-30 from both sides
x = 40
Set the two values equal to each other with 18x-2=12x+2 and then plug it in to the equation and solve
Answer: A.
Step-by-step explanation:
To answer this, you must first understand what fractional exponents mean.
An exponent of 1 is simply the base itself. 7^1 = 7.
An exponent of 2 is squaring the base: 7^2 = 49.
An exponent of 1/2 is taking the square root of the base: 7^(1/2) = sq root of 7
Therefore, an exponent of 1/3 is taking the cube root of the base.
In this case, the base is 2.03 * t.
Therefore, this can be represented as the cube root of the product of 2.03 and the age of the mammal, so the answer is A.
