1.Proportional reasoning compares ratios to answer questions. We can use proportional reasoning to solve some questions directly, such as which size of laundry detergent is the cheapest per load, or what the dimensions of the model car should be.

3.The question is how many ways

There are as a many ways to solve a math problem as you can think of.(Some are shorter or easier than others.)

Essentially, an innfinite number.

sorry I have no idea other questions

Find a solution of the quadratic equation.6x squared + 7x + 2 =0

worty [1.4K]

Given the equation:

$6x^2+7x+2=0$

We will use the following rule to find the solution to the equation:

$x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}$

From the given equation: a = 6, b = 7, c = 2

So,

$\begin{gathered} x=\frac{-7\pm\sqrt[]{7^2-4\cdot6\cdot2}}{2\cdot6}=\frac{-7\pm\sqrt[]{1}}{12}=\frac{-7\pm1}{12} \\ x=\frac{-7-1}{12}=-\frac{8}{12}=-\frac{2}{3} \\ or,x=\frac{-7+1}{12}=-\frac{6}{12}=-\frac{1}{2} \end{gathered}$

So, the answer will be option B) x = -1/2, -2/3

The first terms of a geometric sequence are as follows.

Flauer [41]

The fourth and fifth term of this sequence is -30 and -10 respectively.

Data;

first term (a) = -810
common difference (r) = ?

<h3>Common Difference</h3>

The common difference in a geometric progression is the ratio between two successive terms.

Let's find the common difference in this sequence

$r = \frac{-270}{-810} \\r = \frac{1}{3}$

The nth term of a geometric sequence is given as

$T_n = ar^n^-^1\\$

The next two terms of this sequence will be 4th and 5th term.

The fourth term of this sequence is

$T_4 = ar^4^-^1\\T_4 = -810 * (\frac{1}{3})^3\\ T_4 = -810 * \frac{1}{27}\\ T_4 = -30$

The fifth term of this sequence is

$T_5 = ar^5^-^1\\T_5 = -810 * (\frac{1}{3})^4\\T_5 = -810 * \frac{1}{81} \\T_5 = -10$

The fourth and fifth term of this sequence is -30 and -10 respectively.

Question 2(Multiple Choice Worth 5 points) (02.01 LC) Simplify negative 8 over 3 divided by negative 2 over 6.. −8 −4 4 8

Nana76 [90]

Answer:

Step-by-step explanation:

we have

$\frac{(-8/3)}{(-2/6)}$

we know that

To divide fractions take the reciprocal (invert the fraction) of the divisor and multiply the dividend

$(-\frac{8}{3})(-\frac{6}{2})$

Multiply the numerators and denominators

$(\frac{8*6}{3*2})$

$(\frac{48}{6})=8$

If for an A. P d = -4 then t20 - t15 is what?

Vinil7 [7]

Answer:

As P. d=-4

Step-by-step explanation:

so multiplying both side of equation by - 1

=> - P.d=4. and since 20 =5×4 so 20=5(-P.d) ==> - 5t(P.d)

=> and as -t15=-t20+t5 so it is +5t(P.d)+t5

so - 5t(P.d) +5t(P.d) +t5

answer is t5
