Answer:
The answer is 600
Step-by-step explanation:
Front end estimation is a method of rounding use to make operations more easily and obtain approximate answers. Is called front end because we take the first digit of the number or the "front digit" and round our number to the nearest value detemined by our front end digit, making zeros the other numbers until the end.
In your case we have:
788.44 - 7 is the front number - in hundreds place - we round to nearest hundred 788.44 and this is 800.
225.6 - 1 is the front number - in hundreds place - we round to nearest hundred 225.6 and this is 200.
We perform the operation and obtain : 800-200 = 600.
Answer:
x = -16/11
Step-by-step explanation:
28/(x+4)=11
28=11(x+4)
28=11x+44
11x=-16
x=-16/11
Value: Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies.
The absolute value of a number is never negative. The absolute value of 5 is 5
Answer:
The correct answer is second option
3π in²
Step-by-step explanation:
<u>Points to remember</u>
Area of circle = πr²
Where r is the radius of the circle
<u>To find the area of outer ring</u>
Here radius of large circle = 1 + 1 = 2 in and
radius of small circle = 1 in
Area of outer ring = Area of large circle - area of small circle
= π2² - π1²
= 4π - π
= 3π in²
The correct answer is second option
3π in²
2.5
If you add and divide do one it helps
