Step-by-step explanation:
y is inversely proportional to a*3. when y=10, a=2. a is directly proportional to x. when x=4, a=20. find the formula of y in terms of x
The first statement should be;
y is inversely proportional to a³.
Answer:
y = 0.64/x³
Step-by-step explanation:
y is inversely proportional to a³. This is;
y ∝ 1/a³
Thus, y = k(1/a³).
Where k is the constant of proportionality.
When y = 10, a = 2.
Thus; 10 = k(1/2³)
10 = k/8
k = 80.
Thus; y = 80(1/a³) - - -(1)
Also, a is directly proportional to x. Thus;
x ∝ a
So, x = ka
when x = 4, a = 20
Thus;
4 = 20k
k = 4/20
k = 1/5
Thus;
x = a/5
a = 5x
Put 5x for a in eq 1 to get;
y = 80(1/(5x)³)
y = (80/125) × 1/x³
y = 0.64/x³

4. Which of these points does not lie on the graph of y=-2x+7?
(A) (-1,9
(B) (4,-1)
(C) (-3,1)
(D) (-2.11)
The point (-3,1) is not passing through the graph y = -2x + 7 so option (C) will be correct.
How to plot a graph?
A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
After that, we need to substitute the values of x's and y's into the coordinate geometry.
Given that a line y=-2x+7
Now in order to satisfy any point of this function then the value or
coordinate should satisfy the function or line.
So by checking option (A) 9 = -2(-1) + 7 = 9 so its satisfy.
So all options except (C) are satisfying.
Option (C) ⇒
-2(-3) + 7 ≠ 1
Hence "The point (-3,1) is not passing through the graph y = -2x + 7".

The cost to purchase a song from iTunes is $0.99 per song. To purchase a song from Napster, you must be a member. The Napster membership is $10.
In addtion, each song cost $0.89. Write the equation to determine when iTunes and Napster will cost the same amount.
Equation:
Answer:
It will take 100 songs for the monthly price of Napster to cost the same as iTunes.
Step-by-step explanation:
Let's create two equations to represent iTunes (T(d)) and Napster (N(d)):
T(d)=0.99d
N(d)=0.89d+10
In order for us to find when the two prices will be the same, let's set the equations equal to each other and solve for x:
0.99d=0.89d+10
0.1d=10
d=100

What value of n will make this equation correct. 3/10 n = 4/5
Answer:
n =[tex]\frac{5}{10}[/tex]
Step-by-step explanation:
Answer:
n= 2 and two thirds
Step-by-step:
this is the equation
3/10n=4/5
so to get n by itself, you multiply both sides by 10/3. I did 4/5 times 10/3 and I got 2/2/3, or two and two thirds

.5333333 repeating as a fraction
Answer:
The answer is 8/10
Step-by-step explanation:
When you convert a decimal into a fraction especially a repeating decimal it could be a little complicated but here is what you had to do to find that answer
Step 1: Let x equal the decimal number
Which is x = 0.533333
And with 1 digit in the repeating decimal group create a second equation by multiplying both sides by 10^1 = 10
Step 2:
10x = 0.5333333
Now subtract equation 1 from equation 2
which is
10x = 5.333333
x = 0.5333333
--------------------------
9x - 4.8
We get
9x - 4.8
Step 3: Solve for x
X = 4.8/9
Multiply to eliminate 1 decimal place.
Here you multiply top and bottom by 1 10's
= 10^1 = 10
4.8/9 x 10/10 = 48/90
Step 4: Find the Greatest Common Factor (GCF) of 48 and 90,
if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 6,
48 ÷ 6/90 ÷ 6 = 8/15
Step 5: Therefore
X = 8/15
And in conclusion
0.5333333 = 8/15
So 8/15 is the answer
Have a nice day!

What is the equation in slope-intercept form of the line that passes through the points(-4,2) and (12,6)?
Answer:
y=1/4x+3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(6-2)/(12-(-4))=4/(12+4)=4/16=1/4
y-y1=m(x-x1)
y-2=1/4(x-(-4))
y-2=1/4(x+4)
y=1/4x+4/4+2
y=1/4x+1+2
y=1/4x+3

Muhammad is getting paid x dollars and receives a raise of 10% of those x dollars.
New hourly wage is therefore:
= x + (10% * x)
= x + 10%x
= x + 0.1x

An amateur drama group hire a theatre for their production. They expect to sell all 850 tickets, some at $12 and the rest at $8. The group require the ticket sales to cover their $3760 production costs and to make a profit of $4000. If they are to exactly achieve this target and their expectations regarding ticket sales are correct how many of the 850 tickets should they charge $12 for and how many should they charge $8 for?
Answer:
610 tickets for $8, and 240 tickets for $12.
Step-by-step explanation:
x + y = 850
8x + 12y = 7760
x = 850 - y
8(850-y) + 12y = 7760
6800 - 8y + 12y = 7760
4y = 960
y= 240
x + 240 = 850
x= 610
Answer:
240 = no. of $12 tickets
610 = no. of $8 tickets
Step-by-step explanation:
Let x = no. of $12 tickets
y = no. of $8 tickets
12x = income from selling x $12 tickets
8y = income from selling y $8 tickets
If they are to make a profit of 4000, then they need to have a total income from sales of $7760
So, x + y = 850 and 12x + 8y = 7760
y = 850 - x 12x + 8(850 - x) = 7760
12x + 6800 - 8x = 7760
4x + 6800 = 7760
4x = 960
x = 240 = no. of $12 tickets
y = 850 - 240
= 610 = no. of $8 tickets
In ΔMNO, n = 85 inches, o = 10 inches and ∠M=56°. Find the length of m, to the nearest inch.
Answer:
80
Step-by-step explanation:
Delta math math
The length of m in triangle MNO is approximately 80 inches.
What is a Triangle?Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles.
In ΔMNO, n = 85 inches, o = 10 inches, and ∠M=56°.
In this case, we are given the lengths of sides n and o and the measure of angle M. We can use the law of cosines to solve for the length of side m:
⇒ m² = n² + o² - 2 × n × o × cos(∠M)
We are given that n = 85 inches, o = 10 inches, and ∠M = 56°. We can use these values to solve for m:
⇒ m² = 85² + 10² - 2 × 85 × 10 × cos (56°)
We can use a calculator or look up the value of cos 56° to find that it is approximately 0.6. Plugging this value into the formula above gives us:
⇒ m = 79.8397 ≈ 80 inches
Therefore, the length of m in triangle MNO is approximately 80 inches to the nearest inch.
