Answer:
107.9 ft
Step-by-step explanation:
Imagine Kite is a point A. The person ,who keeps the string is point B.
The height of flying is AC=85 ft. So we have right triangle ABC :angle C=90 degrees, angle B is 52 degrees. Length of AB (triangle ABC hypotenuse) is the length of the string.
AB=AC/sinB=85/sin52=107.8665...=approx 107.9 ft
The length of the string is 86.1 ft.
As per the given data:
Height of the kite flying from the ground = 78 ft
The angle of elevation of the kite from the ground = 65°
From the diagram, we can clearly observe the right-angled triangle with perpendicular as 78 ft if formed.
The length of the string is the hypotenuse.
By using the trigonometric ratio sinθ.
sinθ = Perpendicular / Hypotenuse
sin65° = 78 / Hypotenuse
0.906 = 78 / Hypotenuse
Hypotenuse = 78 / 0.906
Hypotenuse = 86.1 ft
Hence, the length of the string is 86.1 ft.

A triangle has two sides of length 19 and 3. What is the largest possible whole number length for the third side?
========================================================
Explanation:
Consider a triangle with side lengths a,b,c such that a < b < c
a = 3 and b = 19 are the two known sides
Let c be the missing side length
The missing side has the property that...
b-a < c < b+a
19-3 < c < 19+3
16 < c < 22
Meaning that if c is a whole number then it can take on any of these values {17, 18, 19, 20, 21}
So c = 21 is the largest possible third side, where only whole number sides are considered.
We can't have a third side of 22 because the two other sides add to a+b = 3+19 = 22 and a triangle wouldn't form (instead only a straight line would). I recommend cutting out strings of paper trying this out yourself.
---------------
Side note: The inequality b-a < c < b+a is a variation of the triangle inequality theorem.

Zelie planned for a square pool to have a side length of 28 ft but found that it needs to be 14 ft long to fit in her backyard. She found the change of scale below. StartFraction 28 feet minus 7 over 14 feet minus 7 EndFraction = StartFraction 21 over 7 EndFraction Which is Zelie's error? Zelie should have divided both numbers by 14. Zelie should have written the ratio as StartFraction 28 feet over 7 feet EndFraction. Zelie should have written the ratio as StartFraction 14 feet over 28 feet EndFraction.
Answer:
Zelie should have divided both numbers by 14
Step-by-step explanation:
Given
[tex]Actual = 28[/tex]
[tex]Measured = 14[/tex]
Required
Spot and correct Zelie's mistake
[tex]Zelie = \frac{28 - 7}{14 - 7} = \frac{21}{7}[/tex]
Scale is calculated as:
[tex]Actual = Measured * Scale[/tex]
[tex]28 = 14 * Scale[/tex]
Divide 28 and 14 by 14
[tex]28/14 = 14/14 * Scale[/tex]
[tex]2 = 1 * Scale[/tex]
[tex]2 =Scale[/tex]
[tex]Scale = 2[/tex]
Notice at this point:
[tex]28/14 = 14/14 * Scale[/tex]
Both sides were divided by 14.
Hence, option A answers the question.
Answer:
A. Zelie should have divided both numbers by 14.

A calculator screen shows a number in scientific notation as 4.67e-8 write this number in standard form
Answer:
467 000 000
Step-by-step explanation:
4.67e-8 is rewritten as 4.67 x 10^-8.
Negative -> decimal with lots of places, Positive -> big, big number
Move the decimal place right 8 times so you end up with a small decimal.
4.67 -> 467000000

The equation below can be used to determine I, the am
simple interest on a loan.
I= prt, where p is the principal, r is the rate of the loan,
the length of the loan in years.
Which of these is the equation solved in terms of r?
Given :
The equation below can be used to determine I (simple interest) on a loan as follows :
[tex]I=Prt[/tex] ...(1)
P is principal, r the rate of the loan, t is the length of the loan in years.
We need to find the equation to solve in terms of r. We can find the value of P.
Dividing both sides of equation (1) by rt. So,
[tex]\dfrac{I}{rt}=\dfrac{Prt}{rt}\\\\P=\dfrac{I}{rt}[/tex]
So, P can be solved as : [tex]P=\dfrac{I}{rt}[/tex].

12k+6=4k–8 what is the value of K?
Answer:
k = 28/7 which equals 4
Step-by-step explanation:
1/2k + 6 = 4k - 8
1/2k - 4k = -8 - 6
1/2k - 8/2k = -14
-7/2k = -14
k = -14 * - 2/7
k = 28/7 which equals 4
Answer:
k=-7/4 or -1.75

A hole is accidentally made in a water tank. On the first day, 32 gallons of water leak from the tank. Each day after that, workers are able to decrease the number of gallons leaking by 8% of the leakage on the day before. What is the total number of gallons of water that leaked from the tank?
Answer: 34.78 gallon
Step-by-step explanation:
Exponential equation for decay:
[tex]A=P(1-r)^t[/tex] , where p = initial amount, r= rate of decay , t= taime
As per given,
r= 8% = 0.08
For days 1 , i.e. at t= 0 , P= 32 gallons
[tex]1=32(1-0.08)^t\\\\\Rightarrow\ \dfrac{1}{32}=(1-0.08)^t \\\\\Rightarrow\ \ln \left(\frac{1}{32}\right)=t\log (0.92)\\\\\Rightarrow\ t=-\frac{5\ln \left(2\right)}{\ln \left(0.92\right)}=41.5\approx42[/tex]
Total water = [tex]\dfrac{a(1-r^n)}{1-r}=\dfrac{32(1-0.08^{42})}{1-0.08}=34.782[/tex]
hence, the the total number of gallons of water that leaked from the tank = 34.78 gallon approx.

a scale on a map reads 2in 150ft find the actual distance if the length on a map is 4.5 inches
Answer:
4.5 in. is equivalent to 337.5 ft.
Step-by-step explanation:
The given parameters are;
The scale of the scale map is 2 in. to 150 ft.
The measured length on the scale map = 4.5 inches
The actual distance of the location is given as follows;
2 in. is equivalent to 150 ft.
Therefore;
1 in. is equivalent to 150 ft./2 = 75 ft.
4.5 in. will be equivalent to 4.5 × 75 ft. = 337.5 ft.
4.5 in. will be equivalent to 337.5 ft.

Write equation in slope intercept form (x=mx+b). Find the slope (x) and the y-intercept (b) of the line
Answer:
y = (2/3)x - 1
Step-by-step explanation:
By refering the graph, we can see that y-intercept(b) = (a point of the y-axis) which is -1.
the coordiates i have taken:
(-3 , -3) ------ (-3 =x1, -3 =y1)
and
( 3, 1 ) --------( 3 = x2, 1 = y2)
To find slope,
slope(m) = rise/run = ( y2 - y1 ) / ( x1 - x2 )
=> ( 1 - (-3) ) / ( 3 - (-3) ) -----( negative × negative = positive. Hence the signs are positive. )
=> ( 1 + 3 ) / ( 3 + 3 )
=> 4 / 6
=> 2 / 3 ------(simplied after numerator and denominator got divided by 2)
now,
b = -1
m = 2/3
x = x ----(x remains same)
Therefore,
y=> mx + b
by substituting the values, we get,
y=> (2/3)x - 1
