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 solutions does the equation 3x + 6 = -1 - 3 + 4x have?
O Two
O None
One
O Infinitely many
Answer:
one
Step-by-step explanation:
3x + 6 = -1 - 3 + 4x
Combine like terms
3x+6 = -4 +4x
Subtract 3x from each side
3x+6-3x = -4+4x-3x
6 = -4+x
Add 4 to each side
4+6 = -4+x+4
10 =x
There is one solution
Only one it's 10

y + 2 = 6(x + 3) B
y − 3 = −6(x − 2) C
y − 2 = 6(x − 3) D
Answer:
A

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].

Answer:
33.49 cubic inches
Step-by-step explanation:
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.

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.

Let p and h represent pay and hours worked respectively,
p = kh
k = p/h = 148.5/18 = 8.25
p= 8.25h
90.75 = 8.25h

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

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]
