Use Pythagorean’s Theorem. a^2 + b^2=c^2.
a^2 + 35^2 = 37^2
a^2 + 1225 = 1369 then subtract 1225 from both sides.
a^2 = 144 then find the square root of both sides
a = 12
Answer: 3.87 * 10^5, or 387000
Step-by-step explanation:
Move the decimal to the left and increase the power.
If you want to have it expanded, move the decimal point to the right 4 times of the original to get 387000.
Answer: y = -35x + 105
Step-by-step explanation:
The graph represents a function that is between hours and miles and to determine the equation which belong to this graph, we need to find the slope first by using two points from the graph which are (0, 105) and (3, 0).
The definition of slope is
m = (y2 - y1)/(x2 - x1)
= (0-105)/3-0
= -105/3
= -35
The slope is -35 and remember that the slope is the coefficient of the variable x. Therefore, the answer is:
y = -35x + 105
5x + 7 + 2x = 0
7x + 7 = 0
7x = -7
x = -7/7
x = -1
Answer:
A. 200 miles/hour
Step-by-step explanation:
600 divided by 3, since division is the opposite of multiplication we can multiply:
3 X 150 = 450
3 X 50 = 150
we can add 150 and 50 together to get 200 and that's your answer
