Answer: 1719.22 mi squared
Step-by-step explanation:
you have to find the height first.
you only have r and hypotenuse
so
a^2 + b^2 = c^2
13^2 + b^2 = 29.1^2
169 + b^2 = 846.81
b^2 = 846.81 - 169
b^2 = 677.81
b = 26.03
height = 26.03
surface area formula :
_______
πr(r+_/h^2+r^2)
___________
π(13) [13 + _/26.03^2 + 13^2]
= 1719.22

Please help! The expressions 3x - 9 and 23 - 5x represent the lengths (in feet) of two sides of an equilateral triangle. Find the length of a side. Show your work.
Answers
3x - 9= 23 - 5x
And then you solve for x
-22=-2x
X=11
We are dealing with an equilateral triangle which has 3 equal sides.
length of a side = 3 ft
Since the three sides of an equilateral triangle are equal and we are given two sides to have lengths of 3x - 9 and 23 - 5x , it means that;
3x - 9 = 23 - 5x
Rearranging this gives;
3x + 5x = 23 + 9
8x = 32
x = 32/8
x = 4
putting 4 for x in 3x - 9, we have;
3(4) - 9 = 3 ft
Thus,
length of a side = 3 ft

43..
sorry if thats wrong.
Answer:
46
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
~
First, subtract 8 from both sides of the equation:
2x + 8 (-8) = 16 (-8)
2x = 16 - 8
2x = 8
Next, divide 2 from both sides of the equation:
(2x)/2 = (8)/2
x = 8/2 = 4
Next, plug in 4 for x in the given expression:
x + 42
(4) + 42 = 46
46 is your answer.

A steel ball is dropped from a height and hits the ground 6.7 seconds after its release. From what height (in feet) was the ball released?
Answers
Step-by-step explanation:
Acceleration = g = 32.17ft/s²
Initial velocity = 0ft/s
Time taken = 6.7s
Using Kinematics,
we have s = ut + 0.5at².
=> s = (0)(6.7) + 0.5(32.17)(6.7)²
=> s = 722.06ft.

(a) median = 6
(b) median = 14
(c) median = 37
(d) median = 19
(e) median = 4.5
(f) median = 15
(g) median = 126
(h) median = 345
(i) median = 50
(j) median = 75
Step-by-step explanation:
The median of the ungrouped data is obtained by arranging the numbers from the lowest to the highest number, then select the middle number. If you have two numbers in the middle, sum the two numbers and divide it by 2.
(a) in order: 3 4 4 6 7 8 8
median = 6
(b) in order: 11 11 12 14 15 16 17
median = 14
(c) in order: 31 31 34 37 38 41 42
median = 37
(d) in order: 17 17 18 19 19 21 23
median = 19
(e) in order: 3 3 3 4 5 6 7 9
median = (4 + 5) / 2 = 4.5
(f) in order: 12 14 14 14 16 18 19 20
median = (14 + 16)/2 = 15
(g) in order: 120 121 124 128 129 131
median = (124 + 128)/2 = 126
(h) in order: 321 339 342 345 352 358 362
median = 345
(i) in order: 43 46 49 49 51 51 51 52
median = (49 + 51)/2 = 50
(j) in order: 68 70 73 74 76 77 77 81
median = (74 + 76)/2 = 75

Your client gets a bill from a French vendor for 100 euros on March 1 at an exchange rate of 1.2 dollars to the euro and pays on April 1 at an exchange rate of 1.3 dollars to the euro. What would you see in the Transaction Journal for the bill payment?
Answers
Answer:
The Transaction that to be entered in the Account would be:
Account payable A/c Dr. 130$
To Bank A/c 130$
Also,
Profit and Loss A/c Dr. 10$
To Foreign Exchange Fluctuation loss A/c 10$
Step-by-step explanation:
client received a bill as per question mentioned of 100 Euros on March 1 when the exchange rate is 1 Euro = 1.20 $,
Accordingly the price liable to be paid as on date 1 March is
100 Euro × 1.20= 120 $ .
Further, the client is agreed to pay the amount on the April 1 when the exchange rate stands out at 1.30 $, that specifies that the client now has to pay the extra price due to the exchange rate fluctuation i.e.
(1.30 - 1.20)$ = 0.10$ to the French vendor.
Therefore , the Transaction that to be entered in the Account would be:
Account payable A/c Dr. 130$
To Bank A/c 130$
Also,
Profit and Loss A/c Dr. 10$
To Foreign Exchange Fluctuation loss A/c 10$
