a is 25% of b
b is 30% of c.
Write the ratio a:b:c
Give your ratio in its simplest form.
Answer:
40a : 10b : 3c
Step-by-step explanation:
We can write this information more mathematically by saying:
[tex]a = \frac{1}{4} b[/tex]
[tex]b= \frac{3}{10} c[/tex]
This can be written as ratios as well by making them all integers so:
4a : b
10b : 3c
By making the b's in both equations the same, we can link all the ratios together so:
40a : 10b
10b : 3c
So,
40a : 10b : 3c
How many different strings can be made from the letters in ORONO using some or all of the letters? (15 pts.)
The number of different strings that can be made from the letters in ORONO using some or all of the letters is 63
What is the number of permutations in which n things can be arranged such that some groups are identical?Suppose there are n items.
Suppose we have
[tex]i_1, i_2, ..., i_k[/tex]
sized groups of identical items.
Then the permutations of their arrangements is given as
[tex]\dfrac{n!}{i_1! \times i_2! \times ... \times i_k!}[/tex]
We're given the word ORONO.
Case 1: One letter string:3 ways: O, R, or N
Case 2: Two letter string:Subcase: Consists O:
5 ways: OR, RO, ON, NO, OO
Subcase: Doesn't consist O:
2 way: RN, NR
Total permutation under this case = 5+2 = 7
Case 3: Three letter string:Subcase: Consists 3 'O':
1 way: OOO
Subcase: Consists 2 'O':
6 ways: OOR, ROO, ORO, OON, NOO, ONO
Subcase: Consists 1 'O':
6 ways: ORN, ONR, RNO, RON, NOR, NRO (or that there are 3 distinct letters to be arranged, which can be done in 3! = 6 ways)
Subcase: Doesn't consist O:
0 ways as only R and N cannot form three letter string.
Total permutation under this case = 1+6+6= 13
Case 4: 4 letter string:Subcase: Consists 3 'O':
So, we've got {O,O,O,R,N}
3 'O's are mandatory, so fourth letter is either R or N:
O, O, O, R can arrange themselves in : [tex]4!/3! = 4 \: \rm ways[/tex] (as total 4 words but 3 are identical)
Similarly, O, O, O, N can arrange themselves in 4 ways,
So when 4 letter string from ORONO consists of 3 'O's, then total 4+4=8 distinct strings can be made.
Subcase: Consists 2 'O':
So, we've got {O,O,R,N}
The total permuations of these 4 letters, of which 2 are identital is:
[tex]\dfrac{4!}{2!} = 12[/tex]
Subcase: Consists 1 'O':
0 ways: Single 'O' and one-one R and N cannot form four letter string.
Subcase: Doesn't consist O:
0 ways as only R and N cannot form four letter string.
Total permutation under this case = 8+12 = 20
Case 5: Five lettered string:All 5 letters of ORONO would be used.
There are 3 identical objects, so total number of their permutation is:
5!/3! = 20
Thus, from all these cases, we conclude that:
Total permutations of string letters using some or all letters of ORONO is:
3+7+13+20+20 = 63
Thus, the number of different strings that can be made from the letters in ORONO using some or all of the letters is 63

Use the drawing tools to form the correct answer on the graph. Plot function f on the graph. f(x)= 3, -9
The equation of the function f with solution 3, -9 is x²+6x-27 and the graph of this equation with the use of drawing tools is attached below.
What is the definition of a Function?A function assigns the value of each element of one set to the other specific element of another set.
A function has to be plot which has the value of f(x) as 3 and -9. Here, 3 and -9 are the solution of the function. Thus,
x=3
x-3=0
The second solution is,
x=-9
x+9=0
Multiply both factor for the function as,
f(x)=(x-3)(x+9)
f(x)=x²+9x-3x-27
f(x)=x²+6x-27
This is the required function. The graph of this function is attached below.
Thus, the equation of the function f with solution 3, -9 is x²+6x-27 and the graph of this equation with the use of drawing tools is attached below.

If a₁ = 2 and an = an-1 +5 then find the value of a5. for recursive sequence
Answer:
[tex]a_{5} = 22[/tex].
Step-by-step explanation:
In this recursive sequence, the value of the first term [tex]a_{1} = 2[/tex] is stated explicitly. The value of every other term of this sequence is given as an expression of the previous term.
For example, the value of the term [tex]a_{2}[/tex] ([tex]n = 2[/tex]) is given in terms of the value of [tex]a_{1}[/tex]:
[tex]\begin{aligned}a_{2} &= a_{(2 - 1)} + 5 \\ &= a_{1} + 5\end{aligned}[/tex].
Likewise, the value of [tex]a_{3}[/tex] ([tex]n = 3[/tex]) would be:
[tex]\begin{aligned}a_{3} &= a_{(3 - 1)} + 5 \\ &= a_{2} + 5 \\ &= (a_{(2-1)}+5) + 5 \\ &= (a_{1} + 5) + 5 \\ &= a_{1} + 2 \times 5 \\ &= a_{1} + (3 - 1) \times 5\end{aligned}[/tex].
In general, the value of [tex]a_{n}[/tex] (for integer [tex]n \ge 1[/tex]) would be:
[tex]\begin{aligned} a_{n} &= a_{1} + (n - 1) \times 5 \\ &= 2 + (n - 1) \times 5\end{aligned}[/tex].
Therefore, the value of [tex]a_{5}[/tex] ([tex]n = 5[/tex]) would be:
[tex]\begin{aligned}a_{5} &= a_{1} + (5 - 1) \times 5 \\ &= 2 + (5 - 1) \times 5 \\ &= 22\end{aligned}[/tex].

C:should always include people you can access conveniently.
D:will not change the results of the data.
Answer:
When selecting a sample for a survey, the way you choose your sample: A) may lead to biased results.
Step-by-step explanation:
The way you choose your sample matters a lot in order to help limit the bias in sampling data.
There are four types of random samples: simple, stratified, cluster, and systematic.
There are two types of non-random samples: voluntary response and convenience.
You always want to have a random sample in order to have accurate, non-biased results. Therefore, A) May lead to biased results is the best answer.

Are the line parallel or perpendicular?

ParallelPerpendicular[tex]\Large\textsc{\textbf{Calculations\::}}[/tex]
First , notice that the equation of the second line , 6x=3y+5 , is not written in the same form as y=2x , so determining the slope is hard .
To determine the slope , we need to convert the first equation into slope intercept form .
Subtract 6x on both sides :
0 = 3y+5-6x
Now , subtract 3y on both sides :
-3y=-6x+5
Divide by -3 on both sides :
y=-6/-3x+5/-3
Which simplifies to :
y=2x-5/3 (remember , a negative divided by a negative results in a positive)
Put both equations together :
y=2x and y=2x-5/3
Notice that the slopes are the same . This indicates that the lines are parallel .
Now let's focus on the second maths problem :
Consider the equations below .
x=-4 and y=-2
Are the lines parallel or perpendicular?
The slope of the first line is undefined , and the slope of the second line is zero .
Lines with undefined slopes are vertical , and lines with slopes of zero are horizontal .
Here's something you may have recalled from your Geometry class :
Is a vertical line parallel or perpendicular to a horizontal line ?
The ans is : perpendicular .
Henceforth , the lines x = -4 and y = -2 are perpendicular to each other .[tex]\footnotesize{\texttt{hope helpful~}[/tex]

In science class you are filling a cylindrical beaker with a fluid. The beaker has a circular base with a diameter of 4 inches and a height of 8 inches. You are filling the fluid into a tank that is shaped like a rectangular prism and has a volume of 100 cubic inches. How many times will you have to fill up the cylindrical beaker before the tank is full? Round to the nearest tenth.
0.9947≅1 times you have to fill up the cylindrical beaker before the tank is full.
What is volume?Volume is defined as the space occupied by any body in the three-Dimenions. All three parameters are required for the volume like length,width and hieght of cube or cubied.
here we have a beaker of cylindrical shape the volume of the shape will be calculated as:
[tex]\rm V=\dfrac{\pi}{4}\times d^2\times l=\dfrac{\pi}{4}\times (4)^2\times 8=100.53\ cubc\ inch[/tex]
We have a volume of rectangular prism = 100 cubic inches
So number of times the beaker fill the fluid will be calculated as:
[tex]=\dfrac { Volume \ of\ Prism}{Volume\ of\ beaker}=\dfrac{100}{100.53}=0.9947[/tex]
hence 0.9947≅1 times you have to fill up the cylindrical beaker before the tank is full.

A dinner plate has a circumference of 100.48 cm. What is the area of the dinner plate? Use 7 = 3.14.
Circumference = 2914 Area Пr2
A. 1,607,68 cm2
B. 200.96 cm?
C. 803.84 cm?
D. 50.24 cm
Answer:
803.84, or C.
Step-by-step explanation:
If we know the circumference then we can use that to find the radius!
-
(π =pi)
Area of a circle formula: π · r^2
-
Let us plug in the circumference into the formula (not the area formula, the circumference one!)
c=2πr
100.48=2πr - 2*3.14 =6.28
100.48=6.28r
divide both sides by 6.28!
r= 16
Now, we plug that in the area formula.
π · r^2
3.14 * 16^2
3.14 * 256 =
803.84
