what is 9/10 divided by 3.8 ? By quotient
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
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.

Seven of the 28 dogs at the shelter are purebred. What percent of the dogs are purebred? (Please help I have been stuck on this question for an hour)
The question is set up btw-
Answer:
25% are purebred
Step-by-step explanation:
7 out of 28 dogs are purebred
7 x 10 = 70
28 x 10 = 280
70 / 280 = 2.5 / 10 = 25 / 100 = 25%
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?
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
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

Answer:
x +3 = y
Step-by-step explanation:
So you are looking for mx + b = y
m is the slope
b is the initial value
Try to isolate the y variable
x - y = -3
Subtract x from both sides
-y = -x - 3
Multiply everything by -1 to make the y value positive
y = x + 3

Answer:
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.
