Answer: it's 31.3 percent.
Step-by-step explanation:
55 feet of 80 is 68 percent, to find the remainder you need to subtract 68 by 100, and with that, you get 31.3 percent.
if you want that in feet it's about 25 feet

arrange 5/4 1/2 5/6 in ascending order
Answer:
Order is 1/2 < 5/6 < 5/4
Step-by-step explanation:
1/2 = 0.5
5/6 = 0.83
5/4 = 1.25
0.5 < 0.83 < 1.25
Just convert 'em to decimals....
½ = 0.5
⅚ = 0.83
5/4 = 1.25

in a all-area track meet 271 sprinters enter a 200-meter dash competition. the track has 7 lanes so only 7 sprinters can compete at a time. at the end of each race, the six non-winners are eliminated, and the winner will compete again in later race. How many races are needed to determine the champion sprinter?
The number of races needed to determine the champion sprinter = 39 races.
Calculation of number of racesThe number of sprinters = 271
The number of sprinters per race= 7
The area to be covered for each race = 200m
For every race covered, a champion is selected and the rest is eliminated.
Therefore, to determine the remaining champion from 271 sprinters,
271/ 7 = 38.7
Which is approximately 39 races.

Answer:
medium: 16large: 18Step-by-step explanation:
Using the variable definitions shown, the two given relations are ...
11 +x +y = 45 . . . . . . 45 total orders
x = y -2 . . . . . . . . . . 2 fewer medium orders than large
__
Using the second equation, we can substitute for x in the first equation to solve this system:
11 +(y -2) +y = 45
2y = 36 . . . . . . . . . . collect terms and subtract 9 from both sides
y = 18 . . . . . . . . . . . divide both sides by 2
x = 18 -2 = 16 . . . . use the second equation to find the value of x

m∠3 = 55°
Step-by-step explanation:
m∠1 = m∠4 (parallel lines with same angle)
m∠2 = m∠3 (parallel lines with same angle)
apply whole angle measure equals to 360°
11x -7 + 5x - 5 + 11x -7 + 5x - 5 = 360
32x -24° = 360°

At what point on the curve y = 9 + 2ex − 5x is the tangent line parallel to the line 5x − y = 8?
(x, y) = ?
Answer:
[tex](\ln(5), 19-5\ln(5))[/tex]
Step-by-step explanation:
The line can be represented as y=5x-8, so the slope of the line is 5.
The derivative of the curve is:
[tex]\frac{d}{dx} [9+2e^x-5x]\\=\frac{d}{dx} [9]+\frac{d}{dx} [2e^x]-\frac{d}{dx} [5x]\\=2e^x-5\\[/tex]
We need to set that equal to 5 to find the x coordinate of our desired point
[tex]2e^x-5=5\\2e^x=10\\e^x=5\\x=\ln(5)[/tex]
Now, just plug in x in the curve to solve for y:
[tex]9+2e^{\ln(5) } -5\ln(5) = y\\9+10-5\ln(5)=y\\19-5\ln(5)=y[/tex]
Line 5x y = 8 has a slope of 5. This means that the tangent line that runs parallel to this line must also have a slope of 5.
To solve this equation
dy/dx = 2ex 5 is the derivative of the function y = 9 + 2ex 5x. Consequently, 2ex 5 is equal to the slope of the tangent line at any location.
When we set the slope of the tangent line to 5, we obtain:
2ex − 5 = 5
2ex = 10
e^x = 5
Taking the natural logarithm of both sides, we get:
ln(e^x) = ln(5)
x = ln(5)
Therefore, ln(5) is the x-coordinate of the crossing point.
We can enter this value of x into the original function to determine the y-coordinate:
y = 9 + 2e^(ln(5)) − 5(ln(5))
y = 9 + 10 − 5ln(5)
y = 15 − 5ln(5)
As a result, the intersection is at (ln(5), 15 5ln(5)).
To sum up, (ln(5), 15 5ln(5)) is the point on the curve y = 9 + 2ex 5x where the tangent line is parallel to the line 5x y = 8.

The figure shows a rhombus ABCD. The diagonal DB is produced to E such that BC = BE and CDE = 46°.
Find
(I) BAD
(ii) BCE
Answer:
(i) 88°
(ii) 23°
Step-by-step explanation:
See the picture below.
The numbers added in red are the angle measures. The numbers added in black are the order in which each angle measure was written.
ABCD is a rhombus, so all sides are congruent.
Triangle BCD is isosceles with sides DC and BC congruent, so <DBC is congruent to <BDC. From the sum of the measures of the angles of a triangle, we get m<DCB. Opposite angles of a rhombus are congruent, so m<A = m<DCB. From the sum of the measures of the angles of a triangle and from isosceles triangle ADB we get m<ADB and m<ABD. From m<DBC and supplementary angles, we get m<CBE. From isosceles triangle BCE, we get m<BCE.

Answer:
$21,600
Step-by-step explanation:
h(x) = 5000 · (1.08)^4
5000 · 4.32
h(x)= 21,600
Answer:
$6802.44
Step-by-step explanation:
We will replace x with 4.
h(4) = 5000 · (1.08)^4
Use a calculator from here if you don't want stress.
1.08 x 1.08 x 1.08 x 1.08 = 1.36048896
1.36048896 x 5000 = 6802.4448
Since we are looking at the cost, we will approximate to the nearest hundredth.
6802.4448 ≈ 6802.44
The cost is $6802.44.

For a recent job, a plumber earned $28/hr, and the plumber’s apprentice earned $15/hr. The plumber worked 3 hours more than the apprentice. If together they were $213, how much did he esrn
Answer: (with explanation) (ANSWER AT THE BOTTOM)
et P = number of hours that the plumber worked.
let H = number of hours that the helper worked.
since the plumber worked 3 more hours than the helper, the equation for hours worked is
P = H + 3
-----
since the plumber earned 28 dollars per hour and the helper earned 15 dollars per hour, the equation for amount of money each made is the number of hours each worked times the dollars per hour each earned.
this equation is
(28*P) + (15*H) = 213 dollars
-----
both get the same answer.
-----
-----
substitute for P in the money equation since P is the same as H + 3.
equation becomes
(28*(H+3)) + (15*H) = 213
solve for H.
28*H + 28*3 + 15*H = 213
43*H + 84 = 213
43*H = 129
H = 3
-----
if H = 3, then P = 6 because P = H + 3.
-----
6*28 + 3*15 = 213 so your answer is
Plumber works 6 hoursHelper works 3 hours.now to find the amount each earn by themselves, we just have to multiply by 6 or 3 by their hourly earning.
let's do the Plumber first
28x6=168
now the helper
15x3=45
---------
now to check if that was the right answer, let's add them up...
168+45=213
so, our answer is right.

The plumber worked for 6 hours and earned $168 and the helper worked for 3 hours and earned $45 dollars. In total, they earned $213.Answer:
