Answer:
Step-by-step explanation:
→ We know that co-interior angles add up to 180°, so we can set up an equation
x + 17 + 4x + 3 = 180
→ Collect the x terms
5x + 17 + 3 = 180
→ Collect the integers
5x + 20 = 180
→ Minus 20 from both sides to isolate 5x
5x = 160
→ Divide both sides by 5 to isolate x
x = 32
⇒ Now we know the value of x, we can substitute it in back into m∠f because we know angles on a straight line add up to 180°
4x + 3 when x = 32 ⇔ 4 × 32 + 3 ⇔ 128 + 3 ⇔ 131
Answer:
126720
Step-by-step explanation:
Here, we need to find out what is the length of the rectangle. To do this, we'll divide 800 by 25: 800/25 = 32
So we now know that the length is 32 m and the width is 25 m. So we can now find the perimeter:
(32 + 32) + (25 + 25) =
64 + 50 = 114
The perimeter is 114 m. To find how much is will cost to fence 114 meters, we'll multiply the number of meters by the cost per meter: 114 * $12 = $1368
It will cost $1368.
That is the formula for solving for continuously compound interest.
You want to solve for time "t".
<span>A = Pe^rt
Dividing both sides by "P"
(A / P) = e^r*t
Taking NATURAL LOGS of both sides:
(the natural log of "e" is 1)
ln (A / P) = ln (e^r*t)
</span><span>ln (A / P) = r*t*1
</span><span>ln (A / P) = rate * time
Time = </span><span>ln (A / P) ÷ rate
</span>
Hi There!
Exponents are used in math so its easier to multiply. For example if you have to do 8 * 8 * 8 * 8 * 8 * 8 * 8 * 8, then to make it easier to multiply you could change into the exponent form
that is what exponents are used for in math
Hope This Helps :)
