James and Ahmik went to a bicycle show. Of the bicycles they saw at the show, 32% were blue, 25% were red, 25% were green, and 18% were black. In ratio form, what percent of the bicycles were red or black?
Answer: 43:100
Step-by-step explanation:
Percentage of bicycles that are blue = 32%
Percentage of bicycles that are red = 25%
Percentage of bicycles that are green = 25%
Percentage of bicycles that are black = 18%
Percentage of bicycles that are red or black = 25% + 18% = 43%
Therefore, 43% will be written in ratio form as 43:100

Step-by-step explanation:
[tex]\frac{4^{12}}{4^{-9}}\\[/tex]
Given 4 = a
From the properties of exponents for the example...
[tex]\frac{a^4}{a^{-2}} = \frac{a*a*a*a}{\frac{1}{a^2} } = (a*a*a*a)*a^2 = a^4 * a^2 = a^{4+2} = a^6[/tex]
Therefore, the answer is....
[tex]4^{12}*4^{9} = 4^{12+9} = 4^{21}[/tex]

Answer:
x = 42°
Step-by-step explanation:
Since (3x+3) and 129 are corresponding angles, we can set them equal to one another and solve for x.
3x + 3 = 129
- 3 - 3
3x = 126
/3 / 3
x = 42°
Which ratio is proportional to 18/28 ?
Help me plzzzz i will give brainliest
Answer:
18/21 = 30/35
Step-by-step explanation:
so the problem says 18/21 so if that's the correct ratio to proportion to the answer would be. 30/35. the reason is that you can divide 18 and 21 by 3 to get 6/7 then if you multiply by 5 you get 30/35. Dividing and multiplying both the denominator and numerator keeps the ratio proportional.

How many solutions does the equation 5x + 3x − 4 = 10 have?
a
Zero
b
One
c
Two
d
Infinitely many
Answer:
1.75
Step-by-step explanation:
5x + 3x - 4 = 10
Add Four To Both Sides To Begin Simplifying.
5x + 3x = 14
Now, Combine Like Terms.
8x = 14
Divide:
8x/8 = 1X = X
14/8
X = 14/8
14/8 = 1.75
X = 1.75
Check:
(5 * 1.75) + (3*1.75) - 4 = 10
8.75 + 5.25 - 4 = 10
14 - 4 = 10
10 = 10. This Is True, So X Does Equal 1.75

7/2x + 1/2x = 2 1/2 + 9/2x
solve.
Answer:
x = -121
Step-by-step explanation:
(7/2)*x+(1/2)*x = (9/2)*x+121/2 // - (9/2)*x+121/2
(7/2)*x+(1/2)*x-((9/2)*x)-(121/2) = 0
(7/2)*x+(1/2)*x+(-9/2)*x-121/2 = 0
-1/2*x-121/2 = 0 // + 121/2
-1/2*x = 121/2 // : -1/2
x = 121/2/(-1/2)
x = -121
8) The graphical representation of a linear polynomial is
Curve
Straight line
Parabola
Circle
Answer:
Straight line
Step-by-step explanation:
if for a linear polynomial ax + b, a ≠ 0, the graph of y = ax + b is a straight line which intersects the x-axis at exactly one point, namely, (- b/a, 0). Also, this linear polynomial has only one zero which is the x-coordinate of the point where the graph of y = ax + b intersects the x-axis.

What is the answer to (m^2-7m-11)/(m-8)
Answer:
The final quotient is [tex]\bold{m+1-\frac{3}{m-8}}[/tex].
Step-by-step explanation:
This problem can be solved using two methods: long polynomial division and synthetic division.
Method 1: Long Polynomial Division
We can use long polynomial division to solve the equation. The steps are detailed below the work.
[tex]\displaystyle{\begin{array}{r}\bold{m+1-\frac{3}{m-8}\phantom{)}\\m-8{\overline{\smash{\big)}\,m^2-7m-11\phantom{)}}}\\\underline{-~\phantom{(}m^2-8m\phantom{-b)}}\\m-11\phantom{)}\\\underline{-~\phantom{()}m-8}\\-3\phantom{)}\end{array}}[/tex]
Steps
Set up your division. Place the divisor (the binomial) on the left hand side of the division symbol and the trinomial (or polynomial depending on the amount of terms) on the right hand side of the equation.Divide the divisor by the first term of the trinomial: [tex]\frac{m^2}{m}=m[/tex]Place the result above the first term of the trinomial (above the bar and directly above the first term of the polynomial.Multiply the m by the divisor: [tex]m(m-8) = m^2-8m[/tex]. Subtract this from the original trinomial: [tex](m^2-7m-11)-(m^2-8m)=m - 11[/tex]. Set this below the equation and then divide the leading term of the divisor by the leading term of the remainder: [tex]\frac{m}{m}=1[/tex].Place this to the right of the m located above - in this case, we add because our result is positive.Multiply that by the divisor: [tex]1(m-8)=m-8[/tex].Set this below the remainder from the previous division and subtract: [tex](m-11)-(m-8)=-3[/tex].Finally, divide the original divisor by the remainder: [tex]\frac{-3}{m-8}[/tex]. This divisor needs simplified: [tex]-\frac{3}{m-8}[/tex].Our final new polynomial (once evaluated), is [tex]\bold{m+1-\frac{3}{m-8}}[/tex].Method 2: Synthetic Division
We can also use synthetic division to solve the polynomial.
Table 1 (actual) Table 2 (model)
[tex]\begin{array}{c|ccc}8 & 1 & -7 & -11 \\ & \downarrow & 8 & 8 \\ \cline{2-4} \multicolumn{1}{c}{} & 1 & 1 & -3\end{array}[/tex] [tex]\begin{array}{c|ccc}a & b & c & d \\ & \downarrow & e & f \\ \cline{2-4} \multicolumn{1}{c}{} & g & h & i\end{array}[/tex]
Steps
Determine the coefficients of the polynomial: [tex]m^2-7m-11[/tex]. These are 1, -7, and -11. We need to determine the zero. We do this by setting the divisor equal to zero: [tex]m-8=0\rightarrow m=8[/tex]. Place this value in the upper left hand corner (in place of a).For the first term, we just drop the coefficient below the bar. Therefore, g becomes 1.Multiply a by g to get e : [tex]8 \times 1 = 8[/tex]. Therefore, e becomes 8.Add c to e : [tex]-7 + 8 = 1[/tex]. Therefore, h becomes 1. Multiply a by h to get f : [tex]8 \times 1 = 8[/tex]. Therefore, f becomes 8.Add d to f to get i : [tex]-11 + 8 = -3[/tex]. Therefore, i becomes -3.Our new coefficients are 1, 1, and -3. We lose one power (if the first term is squared, it now does not have an exponent).Use the new coefficients to get our new equation: [tex]m+1-3[/tex].Finally, the last term is the remainder. So, we divide this by the divisor: [tex]m+1-\frac{3}{m-8}[/tex].Our final expression is [tex]\bold{m+1-\frac{3}{m-8}}[/tex].What can be concluded about a pair of triangles with some congruent corresponding parts?

Benson purchased a $1,800 certificate of deposit that earns simple annual interest. At the end of 1 year, the certificate was worth $1,857.60.
What is the annual interest rate on this certificate of deposit?
Answer:
3.2%
Step-by-step explanation:
Here, we want to calculate the annual interest rate
The interest is = Amount - principal = 1857.60 - 1800 = 57.60
‘Mathematically;
Interest = PRT/100
P is 1,800
r is rate
t is time = 1
57.60 = (1800 * r * 1)/100
100 * 57.60 = 1800r
r = 5760/1800
r = 3.2%

Answer:
5 x (3 + y) = 20
Step-by-step explanation:
The total amount collected is 20, so it goes on the right side of the = sign. There was a total of 5 students and each student had to pay an attendance fee of $3, so you need to multiply 5 by 3 because each student had to pay the fee. The students also need to pay a fee for supplies, but we do not know what that amount is, so we put a variable in its place. We need to put the total amount of money that each student pays together, so we put it in parentheses. We put the 5 outside of the parentheses, which are on the left side of the = sign. When you solve this equation, you would find that the supply cost would have to be $1 each.
Which of these statements about savings is incorrect? *
1 point
People often believe they are saving when they buy products at a listed
discount, even if they didn't need the product in the first place
It is extremely difficult to open a savings account, as you typically need at
least $10,000 for your initial deposit
Without a vehicle to save (like a savings account), it's much easier to spend
and harder to keep track of finances
Billions of dollars is spent on marketing to persuade consumers to spend
money instead of saving it
