Answer:
0.8 or 8/10
Step-by-step explanation:
1/10 can be converted to decimal form as 0.1.
70/100 can be converted to decimal form as 0.7
0.1 + 0.7 = 0.8
Another way is making use of a common denominator:
Common denominator --> 100
1/10 --> mutiply numerator and denominator by 10 --> 10/100
10/100 +70/100 = 80/100 = 8/10 = 0.8
After reducing the regular selling price by 1/8, sepaba inc. sold a stereo set for $300. what was the regular selling price?
Answer:
about 342.86
Step-by-step explanation:
300 is only 7/8 the value of the original so you know
7/8x = 300

Let's find out the gradient (Slope " m ") of line q ;
[tex]\qquad \sf \dashrightarrow \:m = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]\qquad \sf \dashrightarrow \:m = \dfrac{4 - 0}{0 - 1}[/tex]
[tex]\qquad \sf \dashrightarrow \:m = - 4[/tex]
Now, since we already know the gradient let's find of the equation of line by using its Slope and one of the points using point slope form of line :
[tex]\qquad \sf \dashrightarrow \:y - 4 = m(x - 0)[/tex]
[tex]\qquad \sf \dashrightarrow \:y = mx + 4[/tex]
Now, plug in the value of gradient ~
[tex]\qquad \sf \dashrightarrow \:y = - 4x + 4[/tex]
here we can clearly observe that, the Area under the curve can easily be represented as :
[tex]\qquad \sf \dashrightarrow \:y < - 4x + 4[/tex]
Since, all the values of y that lies in the shaded region is smaller than the actual value of y for the corresponding values of x in the equation of line q
Given that y = 6 + 4x-x^2express y in the form a.-(x + b)^2, where a and b are
integers. Hence or otherwise , write the coordinates of the turning point of y
Answer:
6 + 4x − x² = 10 − (x − 2)²
the turning point : (2 , 10)
Step-by-step explanation:
6 + 4x − x² = − x² + 4x + 6
= − (x² − 4x) + 6
= − (x² − 4x + 4 − 4) + 6
= − [(x − 2)² − 4] + 6
= − (x − 2)² + 4 + 6
= − (x − 2)² + 10
= 10 − (x − 2)²
Then the turning point of y is (2 , 10)

Answer:
2, 16, 18.
Step-by-step explanation:
The first number might be 4 , 9, 16 or 25.
The other 2 numbers are factors of 18 so could be:
2, 3, 6, 9 or 18.
If square no. = 4 then sum of other 2 = 32 but no 2 numbers will fit the required result.
If it is 9, the sum = 27 then 9 and 18 will fit but that makes 2 square numbers so this is not the answer.
If square no. = 16, the sum of other 2 is 20. 2 and 18 will fit this.

What is the effect on the graph of the parent function f(x) = x when f(x) is replaced with 8f(x)?
A) shifts the line 8 units up
B) shifts the line 8 units down
C) increases the slope of the line by a factor of 8
D) decreases the slope of the line by a factor of 8
Answer:
option: C is correct.
Step-by-step explanation:
since, we are given a parent function f(x) as: f(x)=x.
We are asked to find what change will occur in the function when the parent function f(x) is replaced by f(9x).
let g(x) be the function formed by replacing f(x) with f(9x) i.e.
g(x)=f(9x)=9x.
clearly the slope of the function g(x)=f(9x) is 9. ( since on comparing the equation with the slope intercept form y=mx+c; where m is the slope of the line and c is the y- intercept).
whereas the slope of the function f(x)=x is 1.
Hence there is an increment of slope by a factor of 9.
Hence, option C is correct.

Which equation represents the graphed function?
A : y = -2x + 3
B : y = 2x + 3
C : y = 1/2x + 3
D : y = -1/2x + 3
Answer:
y = - 2x + 3
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (1, 1) ← 2 points on the line
m = [tex]\frac{1-3}{1-0}[/tex] = [tex]\frac{-2}{1}[/tex] = - 2
the line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = - 2x + 3 ← equation of line

(a) The shorted distance between point A and point B is 29.1.
(b) The x-coordinate of the point where the ladybug intersected the x-axis is (-1, 12).
Shortest distance between point A and point B
The shorted distance between point A and point B is straight line, which is calculated as follows;
[tex]d = \sqrt{(x_2-x_1)^2 + (y_2 - y_1)^2} \\\\d = \sqrt{(12--1)^2+ (10--16)^2} \\\\d = 29.1 \ unit[/tex]

The owners of a manufacturing company conducted a survey to determine the mean income of the customers who prefer the company’s brand of clothing. From a random sample of 100 customers, it was determined that their mean income was $47,600. Which conclusion can be made based on this information?
The total population mean must be much greater than $47,600 because there are more people in the total population.
The total population mean cannot be determined by such a small random sample.
The total population mean must be close to $47,600 based on statistical inference.
The total population mean must be much less than $47,600 because, out of a sample of 100, a few people with a very high mean income would skew the data.
The total population mean must be close to $47,600 based on statistical inference.
The entire population mean must be close to $47,600. Then the correct option is C.
What is Mean?The mean is the simple definition of the average of a bunch of numbers. In statistics, one of the markers of central tendency is the mean.
The average is referred to as the arithmetic mean.
It's the ratio of the number of real observations to the total number of observations.
The owners of a manufacturing company conducted a survey to determine the mean income of the customers who prefer the company’s brand of clothing.
From a random sample of 100 customers, it was determined that their mean income was $47,600.
