Answer:
The computer can perform 1051050 calculations in 10 seconds.
Step-by-step explanation:
1. Put the quantity of calculations the computer can perform in 1 second:

2. Multiply the quantity of calculations by 10 seconds:

Note that the units of seconds are cancelled as they appear on the numerator and the denominator, and the final response unit is given in calculations number.
The computer can perform 1051050 calculations in 10 seconds.
Answer:B: 36°
Step-by-step explanation:
We know that ∆ABC is isoceles, making (angle)<ABC and <BCA congruent because base angles of isoceles triangles are congruent.
Because we have parallel lines, we can look for alternate interior angle pairs. <BCA is congruent to <DAC because they're alternate interior angles.
If <BCA is x then so is <ABC.
Since triangles add up to 180° we can add all of the angles (3x+x+x) and set it equal to 180.
3x+x+x=180
5x=180
x=36
If we were looking for <BAC we would plug that back in and solve, but we're looking for <BCA which is equal to x, therefore m<BCA=36°
