Honest people would tell other people what they think honestly. And honestly, I don't know how to answer your question :( Honestly, I feel like I don't deserve to answer this question if I can't come up with an honest answer. I don't know, maybe I come back to this question another day when I'm older and wiser, and have an answer that will impress you with my honesty. But for now, honestly, I feel like I have failed this user.

I have a question related to math my question is if 41,630 = 4,1630 x 10^x what would x equal?
Answer:
x = 0
Step-by-step explanation:
its quite simple because 10 raised to the power '0' is 1, so 41,630 ×1 is the same.
don't know about the second figure but the comma doesn't change it..
Determine if the triples below are right triangles.
Port A: 290, 696, 750
Port B: 514, 684, 855
part C: 450, 1080, 1170
Answer:
Part A is not a rt triangle
Part B is not a rt triangle
Part C is a rt triangle
Step-by-step explanation:
Part A:
290^2 + 696^2 = 750^2
84,100 + 484,416 = 562,500
Add the numbers on the left to see if the 2 sides are equal.
568,516 ≠ 562,500
Part B:
514^2 + 684^2 = 855^2
264,196 + 467,856 = 731,025
Add the numbers on the left to see if the 2 sides are equal.
732,052 ≠ 731,025
Part C:
450^2 + 1080^2 = 1170^2
202,500 + 1,166,400 = 1,368,900
1,368,900 = 1,368,900

Which functions have graphs with slopes less than -2?
(Check all that apply.)
Answer:
Function 2
Step-by-step explanation:
✔️Slope of function 1:
Slope (m) = ∆y/∆x
Using two points on the line, (0, 4) and (1, 9),
Slope (m) = (9 - 4) / (1 - 0)
Slope (m) = 5/1
Slope (m) = 5
✔️Slope of function 2:
Slope (m) = ∆y/∆x
Using the coordinates of any two given pairs form the table, (0, 1) and (1, -3):
Slope (m) = (-3 - 1) / (1 - 0)
Slope (m) = -4/1
Slope (m) = -4
✔️Slope of Function 3:
The function is given in the slope-intercept form, y = mx + b
m = slope
The function y = 2x - 5, therefore has a slope (m) of 2
Slope = 2
✔️Slope of Function 4:
Slope (m) = -1
✅Thus, the functions that has slopes less than -2 are:
Function 2: slope = -4
Function 1, 3, and 4 all have slopes that are greater than -2

How many kilograms of 30% salt solution by mass and 40% salt solution by mass
should be mixed to form 200 kg of 37% salt solution by mass?
Answer:
60 kilograms of the 30% solution
140 kilograms of the 40% solution
Step-by-step explanation:
Let x = the no. of kilos containing 30% salt (solution 1)
and 200 - x = the no. of kilos containging 40% salt solution 2)
.30x = amount of salt in solution 1
.40(200 - x) = amount of salt in solution 2
.37(200) = amount of salt in the final mixture
salt in solution 1 + salt in solution 2 = salt in final mix.
.30x + .40(200 - x) = .37(200)
Let's multiply thru the equation by 100 to remove the decimal fractions
30x + 40(200 - x) = 37(200)
30x + 8000 - 40x = 7400
-10x = -600
x = 60 kilograms of the 30% solution
200 - 60 = 140 kilograms of the 40% solution
