Answers:
Point A = 0.62Point B = 7/9Point C = 10/9===================================================
Explanation:
Using a calculator, we get the following decimal approximations
1/3 = 0.3332/3 = 0.6677/9 = 0.77810/9 = 1.111Based on that, we see that 0.620 is between 0.333 and 0.667
We can say 0.333 < 0.620 < 0.667
which is the same as 1/3 < 0.62 < 2/3
So, 0.62 is between 1/3 and 2/3
0.62 will be placed at point A.
--------------
Since 7/9 = 0.778 is between 2/3 = 0.667 and 1, this means,
7/9 will go to point B.
--------------
Since 1.111 > 1, this means 10/9 > 1
Therefore 10/9 will go to point C

Step-by-step explanation:
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.

a shopkeeper bought 12pencil for rs16.how much he sell one pencil to gain 50percent
Answer:
1 dozen pen = 13
so
Step-by-step explanation:
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

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.

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
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
In the figure below, ABC is similar to XYZ . What is the length of ZX ? Enter only the number as an integer or decimal. An image shows two similar right triangles, A B C and X Y Z. Triangle A B C is smaller than triangle X Y Z. In triangle A B C, side A B is 2, side B C is 4, and side C A is 3. In triangle X Y Z, side X Y is 7, side Y Z is 14, and side Z X is labeled N.
Given:
Triangle ABC is similar to triangle XYZ.
In triangle ABC AB=2, BC=4, CA=3.
In triangle XYZ, XY=7, YZ=14, ZX=N.
To find:
The length of ZX.
Solution:
If two triangles are similar, then their corresponding sides are proportional.
Since [tex]\Delta ABC\sim \Delta XYZ[/tex], therefore
[tex]\dfrac{AB}{XY}=\dfrac{BC}{YZ}=\dfrac{CA}{ZX}[/tex]
[tex]\dfrac{2}{7}=\dfrac{4}{14}=\dfrac{3}{N}[/tex]
[tex]\dfrac{2}{7}=\dfrac{2}{7}=\dfrac{3}{N}[/tex]
[tex]\dfrac{2}{7}=\dfrac{3}{N}[/tex]
On cross multiplication, we get
[tex]2\times N=3\times 7[/tex]
[tex]2N=21[/tex]
Divide both sides by 2.
[tex]N=\dfrac{21}{2}[/tex]
[tex]N=10.5[/tex]
Therefore, the length of side ZX is 10.5 units.

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
