Answer:
x= 2.4
Step-by-step explanation:
Answer:
2.4 or 12/5
Step-by-step explanation:
1.2/0.96=3/x
convert the decimal into a fraction---- 6/5 /0.96= 3/x
Simplify the complex fraction-----5/4 = 3/x
simplify the equation using cross-mulitpication----- 5 x = 12
divide both sides of the equation by 5--- x= 12/5
Check if the solution is in the defined range

find the slope of the line through (9,0) and (3,8)
Answer: 4/-3
Step-by-step explanation:
Slope (m) = ΔY /ΔX = 4 /-3
ΔX = 3 – 9 = -6
ΔY = 8 – 0 = 8
Tom and Jason both collect marbles Tom has collected 510 marbles and Jason has collected 842 marbles. How many marbles do they on together..?Estimate the total number of marbles nearest to hundred
Answer:
They had 1,352 marbles all together, rounded to the nearest hundred, 1,400.
Step-by-step explanation:
All we have to do is add the number of marbles they collected.
510 + 842 = 1,352
1,352 rounded to the nearest hundred is 1,400.
A statue that is 80 m tall stands on a 625 m2 base. An artist creates a replica using a ratio of 1:15. What is the area of the replica's base?
Answer: [tex]2.78m^{2}[/tex]
Step-by-step explanation:
given data:
height of the statue = 80m.
base of the statue = [tex]625m^{2}[/tex].
scale of the statue replica = 1:15.
solution:
[tex]= 1:15^{2} \\\\\= 1:225\\\\[/tex]
[tex]= \frac{625m^{2} }{225}[/tex]
= [tex]2.78m^{2}[/tex]
the area of the replica is [tex]2.78m^{2}[/tex]
Answer:
2.78 m^2 is the correct answer. :)
What is the polar form of z?

6 StartRoot 2 EndRoot(cos(225°) + isin(225°))
6 StartRoot 3 EndRoot(cos(225°) + isin(225°))
Answer:
A
Step-by-step explanation:
edge
The polar form of z is 6√2(cos(135°) + isin(135°)).
What Is Polar Form of Complex Numbers?Complex numbers are represented in polar form as the complex number's modulus r and argument combined. Given as z = r cosθ + i r sinθ = r (cosθ + i sinθ). the polar form of the complex number z = x + iy with coordinates (x, y) is given. Polar coordinates of real and imaginary numbers in the coordinate system are used to express the polar form. A complex number in a two-dimensional coordinate system is A = x + i y
Given the point z
From the positive real axis, the angle to the point in the second quadrant is calculated (the x-axis). The only options that make sense for the second quadrant are the 135° angles, which fall between 90° and 180°.
The square root of the sum of the squares of z's components determines its magnitude:
|z| = [tex]\sqrt{x^{2} + y^{2} }[/tex]
here x = -6 and y = 6
|z| = √(-6²) + (6²)
z = 6√2
polar form is
z = 6√2(cos(135°) + isin(135°))
Hence the complex form is 6√2(cos(135°) + isin(135°)).

29. My grandson makes wall hangings by stitching
together 16 square patches of fabric into a 4 x 4
grid. I asked him to use patches of red, blue,
green and yellow, but to ensure that no patch
touches another of the same colour, not even di-
agonally.
The picture shows an attempt which fails only
because two yellow patches touch diagonally.
In how many different ways can my grandson
choose to arrange the coloured patches correctly?
9514 1404 393
Answer:
168
Step-by-step explanation:
Below are shown the 7 different kinds of arrangements that can be made. Each of these can be permuted into 24 different arrangements by assigning colors in a different order than the one used here:
{1, 2, 3, 4} ⇒ {green, blue, red, yellow}
Then the total number of possible correct colorings is 7·24 = 168.
__
These colorings were found using a computer program that identified all 168 viable colorings, then eliminated permutations. It started by identifying ways to color 2 rows, then adding rows based on that.

F a person is earning $34,923 per year, approximately how much should they be saving, including retirement and other savings?'
Answer:
$6,984.60 per year.
Step-by-step explanation:
Using a normal and very common budget, you should divide your monthly/annual salary into 3 main tiers, which are the following
50% = necessities (rent, food, bills, etc)30% = lifestyle choices (clothes, entertainment, hobbies, etc)20% = savings (retirement, emergency fund, etc.)If we go by this budget then we would need to turn the 20% into a decimal by dividing it by 100 and then multiply that decimal by the person's annual salary.
20% / 100 = 0.20
$34,923 * 0.20 = $6,984.60
Finally, we can see that the individual should be saving roughly $6,984.60 per year.
The 8th Grade wants to raise money for a field trip that costs $800. 15 students are in charge of fundraising. What is the minimum amount of money they each have to raise to achieve their goals (if they each raise the same amount of money)?
Answer: $54.35
Step-by-step explanation:
If each one of the 15 students raises the same amount, let's define this amount by the variable X, then the total amount they will collect is 15 times X, or:
15*X
And the minimum amount they need to collect is $800
Then we will have the inequality:
15*X ≥ $800
Now we can divide both sides by 15 to get the minimum amount that each student needs to raise:
(15*X)/15 ≥ $800/15
X ≥ $54.33...
Where we should round up the right number to $54.35, because we can not have a $0.0333... and if we round down, they would collect less than $800.
Then the inequality is:
X ≥ $54.35
This means that the minimum amount that each one of the 15 students needs to collect is $54.35
What is the median of the following numbers?
6,4, 1,9,3,8,3,5, 10
Median = 5
Mean = 5.4444444444444
Mode: 3
Range = 9
Minimum = 1
Maximum = 10
How to find Median:
Arrange your numbers in numerical order. Then the second step is to have an odd number, divide by 2 and round up to get the position of the median number. The last step is to find the even number and if you have it, divide it by 2.

The selling price of an item is $720. It is marked down by 30%, but this sale price is still marked up from the cost of $420. Find the markup from cost to sale price.
Answer:
$84
Step-by-step explanation:
720x30=21600
21600/100=216
216=markdown (as a number instead of a percentage)
Now subtract that like this
720-216=504
504= sale price
Then do this
504-420=84
Therefore it is $84

jake earned 30 points out of a total of 43 on his most recent math test. on his social studies test, jake scored 85 out of a possible 124 points.
on evict rest did jake score a higher percentage of the total? just your answer.
Answer: See explanation
Step-by-step explanation:
Your question isn't really clear but let me help.
For Maths test,
Point earned = 30
Total point = 43
Percentage = 30/43 × 100 = 69.77%
Social studies test
Point earned = 85.
Total point = 124
Percentage = 85/124 × 100 = 68.55%
From the above, we can see that Jake scored a higher percentage in the Maths test.

(a) Write the expression in expanded form. log(7x^3/z)
(b) Write the expanded form as a simplified single log. 3log(5) + 2log(x) – log(25)
Step-by-step explanation:
log(7x³/z) = log(7) + log(x³) - log(z).
3log(5) + 2log(x) - log(25) = log(125) + log(x²) - log(25) = log(125x²/25) = log(5x²).

The endpoints of u are 0 (-2,9) and A(6,-3). What is the length of segment ?
A 14.5
B 14.4
C 14
D 13.9
Answer:
[tex]B.\ 14.4\ units[/tex]
Step-by-step explanation:
[tex]We\ are\ given\ that,\\Coordinates\ of\ Endpoint\ O=x_1,y_1=(-2,9)\\Coordinates\ of\ Endpoint\ A=x_2,y_2=(6,-3)\\As\ we\ know\ that,\\The\ length\ of\ line\ segment\ OA\ or\ u\ is\ the\ distance\ between\ its\ endpoints\\ O\ and\ A.\\Hence,\\The\ linear\ distance(d)\ between\ any\ two\ points\ on\ a\ cartesian\ plane,\\ is\ given\ by\ the\ Formula:\\d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\Hence\ here,\\[/tex]
[tex]In\ order\ to\ find\ the\ distance\ between\ O\ and\ A,\ we\ just\ need\ to\ plug\ in\\ its\ respective\ coordinates\ in\ the\ Formula\ above.\\Hence,\\Distance\ between\ O\ and\ A= \sqrt{(6-(-2))^2+(-3-(9))^2} \\Distance\ between\ O\ and\ A= \sqrt{(6+2)^2+(-3-9)^2}\\Distance\ between\ O\ and\ A= \sqrt{(8)^2+(-12)^2}\\Distance\ between\ O\ and\ A= \sqrt{64+144}\\Distance\ between\ O\ and\ A= \sqrt{208}\\Distance\ between\ O\ and\ A \approx 14.42\ or\ 14.4\ units[/tex]
