Forty thousands place or the place value: Ten thousands place
Answer:
The balance would be $160 from whatever it was before the 4 months.
Step-by-step explanation:
Since the bank balance is being added by 40 for each month for 4 months, 4 * 40 is just 4*4 with an extra zero on the end. so that would be $160.
So if the balance before was $40, then the new balance after 4 months would be $200.
If there's no money previously, then there is now $160 after 4 months.
If there's a value before the $40 for 4 months, let me know and I will explain and tell you what it is.
Answer:
11 ft
Step-by-step explanation:
The radius of the area of the circular pattern = how far the sprinkler cam spread water
Area of the circular watering pattern = 379.94 ft²
Area of circle = πr²
Thus,
πr² = 379.94
Divide both sides by π
r² = 379.94/π
r² = 120.938658
Take the square root of both sides
r = √120.938658
r = 10.9972114 ≈ 11 ft
Water can be spread 11 ft away from the sprinkler
To find a fraction equivalent to 3/7 you just multiply the numerator (top number of fraction) and the denominator (bottom number of fraction) by the same number (i.e. 2/2, 5/5, etc.)
3/7 * 2/2 = 6/14
3/7 * 3/3 = 9/21
3/7 * 4/4 = 12/28
3/7 * 5/5 = 15/35
3/7 * 6/6 = 18/42
3/7 * 7/7 = 21/49
3/7 * 8/8 = 24/56
3/7 * 9/9 = 27/63
3/7 * 10/10 = 30/70
All of those are equivalent to the fraction of 3/7.
I hope you got a good grade on your assignment!!! :D
In this case using the elimination method is actually easier, but the question asks you to use substitution method so....
2x+y= -10
3x-y=0
1st equation: It is better to isolate 2x on both sides because the y is going to be positive no matter what, 2x+y=-10 => y=-2x-10
If you isolated 3x for the 2nd equation, the y will be negative, and you have to divide the whole equation by -1 to make it positive
Now we got y=-2x-10, lets substitute it in the 2nd equation and solve for x:
3x-(-2x-10) = 0
5x+10=0
5x=-10
x=-2
Now lets solve for y:
3(-2)-y=0
-6-y=0
y=-6
Lets see if the same is applicable for 1st equation
2(-2)+(-6)=-10
-10=-10
Yess!!
(-2,-6) is the solution
The answer to the question is explained at the beginning
Hope it helps!
