Answer:
28:42
12:21
4:7
Step-by-step explanation:
To get 12:21, divide both numbers by two
To get 4:7, divide 12:21 by 3
Answer:
28:42, 21:14, 7:10.5, 56:84
There are a lot more, but for the basics of ratios you only need to know this:
- The order is very important in the ratio, whatever number came first stays in that order.
- You can only multiply or divide the same numbers. For instance, if the ratio was 1:2, you would multiply or divide the numbers by the same number.
- When you multiply or divide the ratio/numbers, you cannot not only do whole numbers, but also decimals like 0.25 or mixed decimals like 1.5.
- Remember numbers are infinite, so you can multiply or divide your ratio/numbers by any decimal or number.

If l is parallel m and r parallel s explain how you know Angele 1 and Angle 6 are supplementary
Angle 4 and angle 6 are supplementary to each other.
Given : the two line r and s are parallel to each other and there are two transversals
And thus angle 6 and angle 4 are equal because angles corresponding angles are equal. This is because of a theorem which states that angles on the same side of the two parallel lines are equal .
And this further implies that the angle adjacent to angle 4 and angle form will form an angle whose sum would be equal to 180 degree. That is they will form a supplementary angle .
And this angle and angle 1 are equal because these two angles are corresponding angles and as mentioned above because of that theorem they are equal.
Thus from these two above mentioned arguments it is clear that angle 4 and angle 6 are supplementary angles .

3x( 4x +7 ) + 3( 8 + 2 ) = 11( 2x + 3 ) + 11
?
Answer:
[tex]x=\dfrac{1 +\sqrt{673}}{24}, \quad x=\dfrac{1 -\sqrt{673}}{24}[/tex]
Step-by-step explanation:
Given equation:
[tex]3x( 4x +7 ) + 3( 8 + 2 ) = 11( 2x + 3 ) + 11[/tex]
Distribute the parentheses:
[tex]\implies 12x^2+21x+24+6=22x+33+11[/tex]
[tex]\implies 12x^2+21x+30=22x+44[/tex]
Subtract 22x from both sides:
[tex]\implies 12x^2+21x+30-22x=22x+44-22x[/tex]
[tex]\implies 12x^2-x+30=44[/tex]
Subtract 44 from both sides:
[tex]\implies 12x^2-x+30-44=44-44[/tex]
[tex]\implies 12x^2-x-14=0[/tex]
Use the quadratic formula to solve for x.

Therefore:
[tex]\implies x=\dfrac{-(-1) \pm \sqrt{(-1)^2-4(12)(-14)}}{2(12)}[/tex]
[tex]\implies x=\dfrac{1 \pm \sqrt{1+673}}{24}[/tex]

Five more than the product of a number and 8 equals 3 Use y for the unknown variable
Answer
y = -1/4
Step-by-step explanation:
Let the unknown variable be y
5 more than the product of a number and 8 equals to 3 can be expressed mathematically as
Recall, that the unknown variable is y
5 + (8 * y) = 3
Open the parenthesis
5 + 8y = 3
Substract 5 from both sides
5 - 5 + 8y = 3 - 5
8y = -2
y = -2/8
y = -1/4
Jamal is 8 years older than Autumn. In 2 years the sum of their ages will be 70. How old is Jamal now?
We know that
• Jamal is 8 years older than Autumn.
,• In 2 years the sum of their ages will be 70.
Each statement above has to be expressed as an equation. Notice that "8 years older" means +8. So, the equation about the first statement is
[tex]J=A+8[/tex]Now, "in 2 years" means we have to add 2 units to each age, also we have to add them to get 70. The equation about the second equation is
[tex](A+2)+(J+2)=70[/tex]We reduce like terms
[tex]A+J+4=70[/tex]Then, we subtract 4 on each side
[tex]\begin{gathered} A+J+4-4=70-4 \\ A+J=66 \end{gathered}[/tex]Now, we replace the first equation into the last one above.
[tex]\begin{gathered} A+A+8=66 \\ 2A+8=66 \end{gathered}[/tex]We subtract 8 on each side
[tex]\begin{gathered} 2A+8-8=66-8 \\ 2A=58 \end{gathered}[/tex]At last, we divide the equation by 2
[tex]\begin{gathered} \frac{2A}{2}=\frac{58}{2} \\ A=29 \end{gathered}[/tex]Therefore, Autumn is 29 years old.Let's find Jamal's age.
[tex]J=29+8=37[/tex]Therefore, Jamal is 37 years old.For each relation decide whether or not it’s a function(this is one problem I do an online math program with this is considered one problem)

Write the polynomial function of least degree with real coefficients in standard form:
According to the complex conjugate root theorem, if a complex number a+ib is a zero of a polynomial, then its conjugate a-ib is also a zero of than polynomial.
–3 + 4i is zero of the polynomial. So, by complex conjugate root theorem -3-4i is also a zero of required polynomial.
If c is a zero of p(x), then (x-c) is a factor of p(x).
–2, –4, –3 + 4i, -3-4i are zeroes of the polynomials. So, (x+2), (x+4), (x+3-4i), (x+3+4i) are the factors of the required polynomial.
Let the required polynomial be p(x), so
[tex]\begin{gathered} p(x)=(x+2)(x+4)(x-3+4i^2)(x+3+4i^2)_{} \\ P(x)=(x^2+2x+4x+8)(x+3)^2-(4i^2)^2) \\ (a^2-b^2)=(a-b)(a+b) \\ p(x)=x^2+6x+8)(x^2+6x+9-16i^2 \\ i^2\text{=-1} \\ p(x)=(x^2+6x+8)(x^2+6x+9-16(-1) \\ p(x)=(x^2+6x+8)(x^2+6x+9+16^{} \\ p(x)=(x^2+6x+8)(x^2+6x+25) \end{gathered}[/tex][tex]\begin{gathered} p(x)=(x^2+6x+8)(x^2+6x+25) \\ p(x)=x^2(x^2+6x+8)+6(x^2+6x+8)+25(x^2+6x+8) \\ p(x)=x^4+12x^3+69x^2+198x+200 \end{gathered}[/tex]
Combining like terms, we get
Therefore, the required polynomial is x^2 + 12x^3 +69x^2 + 198x + 200
Hence the correct answer is Option C

Answer
Perimeter = 22 units
Explanation
To answer this, we need to note that two tangents to a circle that start from the same point usually have the same lengths.
So,
AD = AE = 6
CD = CF = 4
Since,
AB = 7 and AB = AE + EB
AE = 6
So,
AB = AE + EB
7 = 6 + EB
EB = 7 - 6
EB = 1
FB = EB = 1
So,
AC = AD + DC = 6 + 4 = 10
AB = 7
CB = CF + FB = 4 + 1 = 5
So, the perimeter of the triangle is given as the sum of all its exterior sides
Perimeter = AB + AC + CB
Perimeter = 7 + 10 + 5 = 22 units
Hope this Helps!!!

There are 96 new houses being built in a neighborhood. Last month, 1/3 of them were sold. This month, 1/8 of the remaining houses were sold. How many houses are left to be sold?
Using the given fractions we can say that there are 56 houses left to be sold.
A fraction, which also denotes a component of a whole, or a ratio is any number divided into equal parts. When expressed in common English, a fraction, such as one-half, eight-fifths, or three-quarters, specifies the number of components of a specific size.
1/3 of 96 were sold...
number of houses sold = 1/3 × 96 = 96/3 = 32
So the first month 32 houses were sold.
Number of houses left = 96 - 32 = 64 houses.
number of houses sold next month = 1/8 × 64 = 64/8 = 8
8 houses were sold the second month
number of houses left 64 - 8 = 56
Therefore using the fractions 56 houses were left to be sold.
