HLEP ME PLEASE !!!!!!
Advocard [28]

Answer:

f(x) + g(x) = 3x + 7

Step-by-step explanation:

f(x) = 2x + 2, g(x) = x + 5

f(x) + g(x) = 2x + 2 +x + 5

f(x) + g(x) = 2x +x + 5 +2

f(x) + g(x) = 3x + 7

Kassie recorded the favorite sport of students at her school. She surveyed 800 students. How many more students chose Baseball t
lisov135 [29]

Answer:

40 more kids chose baseball over basketball.

Step-by-step explanation:

The best way to go about this is to use benchmark percentages.

For baseball, 25% of 800 people chose that, so we can do 800/4 to get 200, so 200 students chose baseball

For basketball, we could do 800/5 but that isn't mental math, so we can do 10% of 800 is 80 and 80*2=160. So 40 more kids chose baseball over basketball.

The number of hours a typical student spends per week at school has an Order of Magnitude of 1.
Margarita [4]
If the number of hours in school each week is somewhere between 20 and 40, then it can be written in scientific notation as
  2.0×10¹ to 4.0×10¹

The exponent of 10 in each case is 1, so we can say the Order of Magnitude is 1.
  TRUE


_____
In Engineering terms, the order of magnitude is sometimes considered to be the integer part of the base-10 logarithm of the number.
  log(20) ≈ 1.3010
  log(40) ≈ 1.6021
If we round these numbers to integers, we find the order of magnitude of the first is 1; the order of magnitude of the second is 2. Thus a student who spends 6 hours per day for 5 weekdays in class will have hours with an order of magnitude of 1, while a student who spends 7 hours per day for 5 days each week will have hours with an order of magnitude of 2. This question is best answered by considering "order of magnitude" in the simplistic terms of the answer above: the exponent of 10 in scientific notation.
