<span>This is a simple subtraction question. To find the answer, you simple need to subtract 15 from 104. This equals 89, so there were 89 4th graders at school that day in total. In the instance you're unsure that a subtraction equation is right, you can also add your answers back together to double check, so 89 + 15 = 104.</span>
Answer:
50
Step-by-step explanation:
Steven = 13 marbles
Julio = 13 marbles
Megan has twice the number of marbles as Steven and Julio combined
Megan = 2 (13 + 13) = 2(26) = 52 marbles
Among the options (26, 13, 50, 169, 338), the only reasonable estimate is 50
Answer:

Step-by-step explanation:
To solve this problem, we need to find the linear function. We know that the constant rate of change is -0.5° Celsius per minute. Also, after 60 minutes the temperature was 10° Celsius. So, we have a one point and the slope of the linear function, let's use the point-slope formula

Where the y-intercept is at (0, 40).
Now, we have two points to graph the relation between minutes and Celsius degrees.
Therefore, the room's temperature as a function of time is

Its graph is attached.
The equation to find the air pressure (P(h)) at a height above sea level (h) is given by

Where,
- P(h) is the new pressure at height h
is the air pressure at sea level, and- h is the height (measured in meters).
We want to know the new pressure that is 65% of
. So we should substitute
in P(h) (new pressure) to get the equation:
. Answer choice B is the correct one.
ANSWER: B
Answer:
the lines arent parallel, so you cant use corresponding angles theorem
