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.

A 12 ounce starbucks latte costs $3.36. What is the constant of proportionality that relates the codt in dollars,y,to the number of ounces,x,in a starbucks latte?
Answer:0.28
Step-by-step explanation:
3.36÷12= 0.28
The constant of proportionality is 0.28 dollars per pounds.
An equation is used to show the relationship between two or more numbers and variables.
Let y represent the cost in dollars for x number of ounces.
Since y is proportional to x, hence it van be represented by:
y = kx
where k is the constant of proportionality.
Given that:
A 12 ounce starbucks latte costs $3.36. Therefore:
3.36 = 12k
k = 0.28
The constant of proportionality is 0.28 dollars per pounds.

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

i think 16/12 * 50 =66.66
for one pen = 66.66/100 I am not sure
Answer:
Rs 2
Step-by-step explanation:
12 pencils = Rs 16
50% profit on Rs 16 = 50/100 × 16 = 8
selling price = 16 + 8 = 24
cost of 1 pencil = 24/12 = Rs 2

Answer:
Step-by-step explanation:
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

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

A rectangle has a width of 3∕4 inches and a length of 9∕10 inches. Another rectangle is larger but still proportional to the first rectangle. It has a width of 30 inches and a length of 36 inches. What proportion could model this situation?
Question 1 options:
A)
B)
C)
D)
Answer:
Bigger size / smaller size = 40
Step-by-step explanation:
Notice that we
36 / (9/10) = 30 / (3/4) = 40
Therefore the proportion model would be
Bigger size / smaller size = 40

8) p ≈ -0.213312t^2 +2.08483t +22.9624; p(11) ≈ 20.08; between 20,000 and 20500
Step-by-step explanation:
7) The result of using a graphing calculator to find a quadratic model for the given points is shown in the first attachment. The equation is ...
y = 0x^2 +3x -7 . . . . . A, B, C = 0, 3, -7
The A coefficient of 0 tells you this is a linear equation.
__
8) The quadratic regression model* found by my graphing calculator is ...
p ≈ -0.213312t^2 +2.08483t +22.9624
The "work" is shown in the second attachment. (Apparently, you have a regression tool you're supposed to use.)
Evaluating this equation for t=11 (corresponding to 11 years after 1996), we find ...
p = (-0.213312·11 +2.08483)·11 +22.9624 = -0.261602·11 +22.9624
p ≈ 20.084778 ≈ 20.08 . . . . thousands
The population in 2007 is between 20,000 and 20,500.
_____
* We're not sure exactly what is supposed to be rounded to 2 decimal places. Error tends to creep up if the quadratic coefficients are rounded to 2 decimal places, but you may be expected to enter your answer that way.
The population in thousands is "between 20 and 21" when rounded to 2 decimal places. It makes no sense to compute the population (in people) as 20,084.78, rounded to 2 decimal places. We have chosen 20,000-20,500 as the answer to the question about population in 2007, because the question doesn't ask for thousands.
