The residents of a city voted on whether or not to raise property taxes. The ratio of yes votes to no votes was 4 to 3. If there were 1716 no votes, what was the total number of votes?

what is 9/10 divided by 3.8 ? By quotient

Answers

Given:

[tex]\dfrac{9}{10}[/tex] divided by 3.8.

To find:

The quotient.

Solution:

We have,

[tex]\dfrac{9}{10}[/tex] divided by 3.8.

Mathematically it can be written as

[tex]\dfrac{9}{10}\div 3.8[/tex]

Convert the decimal into fraction by multiplying and dividing by 10.

[tex]=\dfrac{9}{10}\div \dfrac{38}{10}[/tex]

[tex]=\dfrac{9}{10}\times \dfrac{10}{38}[/tex]       [Reciprocal rule of division]

[tex]=\dfrac{9}{38}[/tex]                     (Cancel out the common factors)

[tex]\approx 0.237[/tex]

Therefore, the quotient is [tex]\dfrac{9}{38}[/tex], which is approximately 0.237.

12x^2=24

Answers

Answer:

x=√2 or x=−√2

x=±√2

Step-by-step explanation:

12x^2=24

Step 1: Divide both sides by 12!

12x^2/12=24/12

x^2=2

Step 2: Take the square root!

x=±√2

The solution of the equation 12x² = 24 is x = ±√2.

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Here, the equation is :

12x² = 24

now, to solve for x :

divide both side by 12 :

x² = 24/12

x² = 2

take square root both  side :

x = ±√2

Therefore, the solution of the equation 12x² = 24 is x = ±√2.

Grace is plotting the vertices of a parallelogram on the coordinate graph below. She has plotted the three points shown. Where could she plot the fourth point?

Answers

Answer:

6,2

Step-by-step explanation:

The fourth point of the parallelogram will be (-6,1) so option (C) will be correct.

What is a parallelogram?

A basic quadrilateral with two sets of parallel sides is known as a parallelogram.

A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size.

There are 4 types of parallelograms, including 3 special types. The four types are parallelograms, squares, rectangles, and rhombuses.

The slope of the green lines and red line should be same for being it a parallelogram.

Slope of green line = (7-2)/(3-1) = 2.5

So the only coordinate is matching the slope 2.5 of red line is (-6,1).

Slope = (6-1)/(-4+6) = 2.5

Hence "The fourth point of the parallelogram will be (-6,1)".

The difference between one-half a number and the number is 8 find the number

Answers

Answer:

The number is  48

Step-by-step explanation:

First, let's call the number we are looking for n.

We can then write "two-thirds of the number" as 2/3n

We can also write "one-half of a number" as 1/2n

Finally, we are told 1/2n is the same as 2/3n −8 or: 1/2n = 23n −8  

We can now solve for n: 1/2n − 2/3n = 2/3n −8 − 2/3n 1/2n − 2/3n = −8We next need to get the fractions over common denominators, in this case, 6 by multiplying each fraction by the necessary for of 1: (3/3) 1/2n − (2/2) 2/3n = −8 3/6n − 4/6n = −8 − 1/6n = −8.  

We can finally solve for n by multiplying by -6 to isolate n −6 ⋅(−1/6)n = −8⋅ − 6  

1n = 48

n =48

The radius of the circle is 4 meters.

Thus, 2nd option is correct.

Step-by-step explanation:

Given

Area of a circle = 16π squared meters.

To determine

The radius of the circle = r = ?

Using the formula

Area of circle = πr²

substitute Area of circle = 16π and in the equation

16π = πr²

switch the sides

πr² = 16π

divide both sides by π

πr²/π = 16π / π

r² = 16

r = 4, r = -4

As radiud can not be negative, so

r = 4 meters

Therefore, the radius of the circle is 4 meters.

Thus, 2nd option is correct.
