Answer:$90
Step-by-step explanation: $30 is the cost. 200 is the percent of Mark-up, so you take 100 percent of 30 and add it together then you get 60. Repeat that step for a total of 90. 100 percent of 30 is 30. So 30+ 30+ 30 = 90.
Answer:
See below
Step-by-step explanation:
The three angles inside of the triangle sum to 180
11x + 4 + 3x + 78 = 180
14x +82 =180
x = 7
then B = 11x + 4 = 11(7) + 4 = 81 degrees
C = 3x = 21 degrees
Answer:
According to the passage, whales weight 300,000 pounds on average. Narwhales weigh 2,000 pounds on average.

This is what we call scientific notation. You could solve it normally, or you could use a faster method.
Scientific notation states that the first number that you see, the three, is the first part of the answer. The exponent on the number of zero's that there is.
That means that the answer to 3×
you get 300,000.
Let's do the same thing to Narwhales.
2×
is 2,000.
