What is the value of the expression below when z=9
What is the circumference of the circle
below?
52 yd
A 254.18 yd
B 387 yd
C 199.3 yd
D 163.28 yd
Answer:
D) 163.28 yd
Step-by-step explanation:
to get the circumference, the equation is 2(π * radius)
52 is the diameter, and half of a diameter is the radius.
so the radius of your circle is 26.
now put that into the equation and you get 2(26π), or 52π
pi is infinite, but you can actually get away with multiplying 52 by 3.14, which gives you the approximate answer.
52 * 3.14 = 163.28
so your answer is D) 163.28 yd

On 31 August 2018,Musk Traders purchased a machine on credit for a cost price of R402 500(including VAt at 15%). Machinery is depreciation over six years according to the straight - line basis and there is no residual value on this machine, as it is highly specialized. Musk traders has a 30 June year-end
Calculate the depreciation and accumulated depreciation for 2019 and 2020.
Answer:
Depreciation should be on a value net of VAT.
Cost + (Cost * VAT) = 402,500
Cost + Cost * 15% = 402,500
1.15 * Cost = 402,500
Cost = $350,000
Depreciation is straight line for 6 years so per year is = 350,000/6 = $58,333
2019
In 2019 the June year end from date of purchase will be 10 months.
Depreciation in 2019
= Yearly depreciation * 10/12 months
= 58,333 * 10/12
= $48,611
Accumulated Depreciation 2019
= $48,611
2020
2020 will be a complete year so depreciation
= $58,333
Accumulated Depreciation 2020
= 2019 + 2020
= 48,611 + 58,333
= $106,944

Uno de los problemas ambientales es la escasez de agua. Para proveer de agua a una comunidad, se necesitan 3846 metros de tubería, y cada tubo mide 6 metros de largo. ¿Cuántos tubos se necesitan?
Porfa respondanme con la operacion pls
Responder:
Explicación paso a paso:
Dado el total de tubería necesaria = 3846 m
Longitud de cada tubo = 6 m
Cantidad de tubería necesaria = tubería total / longitud de cada tubo
Cantidad de tubería necesaria = 3846/6
Cantidad de tubería necesaria = 641
Por lo tanto, la cantidad de tubería necesaria será de 641 tuberías.

2) Mr. Riley dove off a cliff that was 30 feet above the surface of the water and descended a total of 100 feet. Which of the equations below can be used to determine his elevation at the bottom of his dive?
a) 30 + 100
b) 30-100
C) 30 + (-100)
d) Both b and c
Answer:
B
Step-by-step explanation:
Mr.Riley was 30 feet above the water, which means he is at +30 above sea level. If he descends 100 feet, that means he goes 100 feet lower then that. 30 - 100 is equal to -70. He is 70 feet under water after he dived. You do not need to know the answer, but it helps to visualize the problem you have, therefore, finding the answer
If a bird is flying 75 ft above the ocean's surface, and a shark is swimming at a depth of 30 ft, what is the distance between the bird and the shark?
Answer:
105 ft
Step-by-step explanation:
since the shark is swimming at a depth of 30 ft mean is -30 ft...
so the distance between the bird and the shark is
7 5 ft - (- 30 ft) = 105 ft

Find the inverse of f(x)= 2x+3/x-1
Answer:
[tex]\displaystyle f^{-1}(x)=\frac{3+x}{x-2}[/tex]
Step-by-step explanation:
We have the function:
[tex]\displaystyle f(x)=\frac{2x+3}{x-1}[/tex]
Find the inverse of f(x). First, we call y=f(x):
[tex]\displaystyle y=\frac{2x+3}{x-1}[/tex]
We have to solve for x. Multiply by x-1:
[tex]y(x-1)=2x+3[/tex]
Operate:
[tex]yx-y=2x+3[/tex]
Join all the x's to the left side and move the rest to the right side:
[tex]yx-2x=3+y[/tex]
Factor:
[tex]x(y-2)=3+y[/tex]
Solve for x:
[tex]\displaystyle x=\frac{3+y}{y-2}[/tex]
Interchange the variables:
[tex]\displaystyle y=\frac{3+x}{x-2}[/tex]
This is the inverse function:
[tex]\boxed{\displaystyle f^{-1}(x)=\frac{3+x}{x-2}}[/tex]

The probability distribution for the random variable follows. a. Is this a valid probability distribution? - Select your answer - b. What is the probability that (to 2 decimals)? c. What is the probability that is less than or equal to (to 2 decimals)? d. What is the probability that is greater than (to 2 decimals)?
Complete question :
X: 20__25 ___30 ___35
f(x): 0.20 _0.20_0.25 _0.35
Probability that x = 30
Probaility that x less than or equal to 25
Probability that X is greater than 30
Answer:
Kindly check explanation
Step-by-step explanation:
To establish if it is a valid probability distribution :
The sum of the probabilities must be equal to 1:
Σf(x) = 0.20 + 0.20 + 0.25 + 0.35 = 1
Hence it is valid
Probability that x = 30
P(x = 30) = 0.25
Probability that x ≤ 25 :
P(x = 20) + p(x = 25)
P(x ≤ 25) = 0.20 + 0.20 = 0.40
Probability that x > 30
P(x > 30) = p(x = 35) = 0.35
A bicycle is traveling at 17 miles per hour.
How many feet will it cover in 60 seconds?
Round your answer to the nearest tenth of a foot.
Answer:
The bicycle will cover about 943.36 feet.
Step-by-step explanation:
1 mile = 5280 ft
5280 x 16 = 84480
84480 / 60 = 1408 ft per minute
40 seconds of 1 minute = .66 or .67 of a minute
1408 x .67 = 943.36

Jenny has three times as much money as Peter. Together they have $44. How much do they each have
Answer:
33 & 11
Step-by-step explanation:
33+11=44
Answer:
jen has 33, Peter has 11
Step-by-step explanation:
j + p = 44 and
j = 3p
substitute j
3p + p= 44
4p + p=44
p = 44/4
p=11
j + 11 = 44
j = 44 - 11
j= 33
