Use compatible numbers to estimate the quotient 358 divided by 3

2 answers:

8 0

Now keep in mind that compatible numbers are numbers that are easy to divide. So i'm going to use 400 and 3, so the 400/3 would give you 133.3 and what this means is that there will be a remainder in the actually quotient and so divide the actually number and compare them and see if the estimated answer is reasonable and so thank you for your question and have a good day.

What is the value a and b in The equation a(3x -8)=b-18x

Misha Larkins [42]

Answer:

$a=\frac{b-18x}{3x-8}\\b=3ax-8a+18x$

Step-by-step explanation:

Solving for A:

$a(3x-8)=b-18x$ - Given

$\frac{a(3x-8)}{(3x-8)}=\frac{b-18x}{(3x-8)}$ - Divide both sides by 3x-8 to isolate a

$a = \frac{b-18x}{3x-8}$ - Simplify

Solving for B:

$a(3x-8)=b-18x$ - Given

$3ax-8a=b-18x$ - Distribute the parenthesis (distributive property)

$3ax-8a+18x=b$ - Add 18x to both sides to isolate b

Solve using the quadratic formula. Show all work. Write each solution in simplest form. No decimals.

lawyer [7]

Given:

The quadratic equation is:

$12a^2+9a+7=0$

To find:

The solution of the given equation in simplest form by using the quadratic formula.

Solution:

If a quadratic equation is $ax^2+bx+c=0$ , then the quadratic formula is:

$x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

We have,

$12a^2+9a+7=0$

Here, $a=12,b=9,c=7$ . Using the quadratic formula, we get

$x=\dfrac{-(9)\pm \sqrt{(9)^2-4(12)(7)}}{2(12)}$

$x=\dfrac{-9\pm \sqrt{81-336}}{24}$

$x=\dfrac{-9\pm \sqrt{-255}}{24}$

$x=\dfrac{-9\pm i\sqrt{255}}{24}$ $[\because \sqrt{-a}=i\sqrt{a}]$

The solutions of the given equations are $x=\dfrac{-9-i\sqrt{255}}{24}$ and $x=\dfrac{-9+i\sqrt{255}}{24}$ .

Therefore, the correct option is B.

An angle whose measure is _____ is rotated more than halfway around a circle

Vikentia [17]

The correct answer is 60⁰.

Step-by-step explanation:

An angle whose measure is 60⁰ is rotated more than halfway around a circle.
Since, we have to find the measure of angle.
As we already know that the angle of rotation about a circle is 360° therefore we have to find more than halfway of this angle.

Considering that an angle is rotated more than halfway around a circle be $\frac{1}{6}$

Multiplying $\frac{1}{6}$ with 360⁰
Therefore, it can show as $\frac{1}{6}$ ×360⁰
Which gives the result to be 60⁰
Hence, when an angle is measured 60⁰, it is rotating more than halfway around a circle.
A single rotation around a circle is equal to 360 degrees.
The measurement of an angle shows the magnitude and direction of the rotation of the angle from its initial position to the final position.
If the rotation is in a counterclockwise direction, it has an angle with positive measure. If the rotation is clockwise, it has an angle which gives negative measure.
