Answer:
You guys have braincells??!!!
Step-by-step explanation:
1 h = 60 min
1 min = 60 s
1 h = 3600 s
66 min = 60 min + 6 min = 1 h + 6 min
92 s = 60 s + 32 s = 1 min + 32 s
66 min and 92 s = 1 h + 6 min + 1 min + 32 s = 1 h + 7 min + 32 s
66 min = 66 · 60 s = 3,960 s
66 min and 92 s = 3,960 s + 92 s = 4,052 s
Answer: 66 mins and 92 seconds are:
1 hour 7 minutes 32 seconds or 4,052 seconds
We know that the sum of the angles in a quadrilateral all add up to 360 degrees. Here, we know all the angle degrees, just indirectly. To get our answer, we can add up all the given expressions together and make it equal to 360 degrees.
x + (x + 22) + x + (x + 22) + 90 + 90 = 360
Now, combine like terms, the solve for x.
2x + 22 + 2x + 22 + 180 = 360
4x + 44 + 180 = 360
4x + 224 = 360
4x = 136
x = 34
Therefore, the value of x in this problem is 34. Hope this helped and have a great day!
Divide known populations:
1028 / 925 = 1.11135
so exponential formula would be 925*1.11135^t
using 15 years: 925 * 1.11135^15 = 4507
linear model: 103(15) +925 = 2470
4507 - 2470 = 2037 more people using exponential
Answer:
<h3>Each of the given pairs is not a solution to the given equation.</h3>
Step-by-step explanation:
Put the x and y values in the equation 4y = -7x + 5 and check the equality of the left and right side of the equation.
A. x = -5 and y = 0
L = 4(0) = 0
R = -7(-5) + 5 = 35 + 5 = 40
L ≠ R
B. x = -3 and y = 4
L = 4(4) = 16
R = -7(-3) + 5 = 21 + 5 = 26
L ≠ R
C. x = 1 and y = 3
L = 4(3) = 12
R = -7(1) + 5 = -7 + 5 = -2
L ≠ R
D. x = 2 and y = -2
L = 4(-2) = -8
R = -7(2) + 5 = -14 + 5 = -9
