Given:
3450 yen is divided in the ratios 2:6:7.
To find:
The difference between the largest share and the smallest share.
Solution:
3450 yen is divided in the ratios 2:6:7. Let the shares are 2x, 6x and 7x.
[tex]2x+6x+7x=3450[/tex]
[tex]15x=3450[/tex]
[tex]x=\dfrac{3450}{15}[/tex]
[tex]x=230[/tex]
Now,
First share is
[tex]2(230)=460[/tex]
Second share is
[tex]6(230)=1380[/tex]
Third share is
[tex]7(230)=1610[/tex]
Here the largest share is 1610 and the smallest share is 460. So, the difference between the largest share and the smallest share is
[tex]1610-460=1150[/tex]
Therefore, the difference between the largest share and the smallest share is 1150 yen.

In the figure, AB, CD, and m∠6 is 151°. (The figure may not be drawn to scale.) What is the measure of ∠2
Answer:
Step-by-step explanation:
Angle 6 is equal to angle 1.
Angle 1 + Angle 2 must equal 180 degrees so
a+151=180
a=29
So angle 2=29 degrees
What is the MAD of these numbers 1,1,4,5,5,5,6,7,7,10,10?
Please give an explanation
Answer:
2.2314
Step-by-step explanation:
To find the mean absolute deviation of the data, start by finding the mean of the data set.
1+1+4+5+5+5+6+7+7+10+10= 61
61÷11= 5.5-2.5= 2.2
Example:
Find the MAD of 2,4,6,8
Step 1 :
Find the mean of the data :
(2+4+6+8) / 4 = 20/4 = 5
Step 2 :
Find the distance between each data and mean.
Distance between 2 and 5 is 3
Distance between 4 and 5 is 1
Distance between 6 and 5 is 1
Distance between 8 and 5 is 3
Step 3 :
Add all the distances :
3+1+1+3 = 8
Step 4 :
Divide it by the number of data :
8 / 4 = 2

Christian is planning a vacation and finds an airplane ticket that cost 180$. He found a promo code offering 17% off. Write a single algebraic expression that can be used to find the cost of Christian’s ticket after the discount.
Answer:
83/100 x 180
Step-by-step explanation:
We have to find the cost of the ticket after the discount.
100% - 17%= 83%
83% of the total percentage of the original price that he needs to pay.
So we do:
83/100 x 180
So, this would be the expression.
Hope this helps!:)
The graph for the system of inequalities without the shading of its solution set is shown on the coordinate grid. Choose the area that would be shaded to show the solution of this system.
9514 1404 393
Answer:
(C) Area 3
Step-by-step explanation:
The first inequality has positive slope and a y-intercept of -5. The variable x has a positive coefficient so we can determine the shading from ...
x ... > 5
That is, larger values of x are in the solution set. Shading is to the right of the line with positive slope, in areas 3 and 4.
__
The second inequality has negative slope and a y-intercept of -3. Both x and y have positive coefficients, so the shading can be determined from either of ...
... 2y < -6 . . . . . . lower values of y are in the solution set
x ... < -6 . . . . . . . lower values of x are in the solution set
These indicate the shading is below and to the left of the line with negative slope, in areas 2 and 3.
__
The area that is in the solution set of both inequalities is Area 3.
Which 2 equations would you use to solve this system?

The difference of two numbers is 4. Their sum is 32. What are the numbers?
• x + y = 4
• x - y = 4
• x + y = 32
• x - y = 32
Answer:
x-y=4
and
x+y=32 is your equation
difference of two number =x-y is equal to 4
sum of two number=x+y is equal to 32
x-y=4.......(1)
x+y=32.......(2)
adding equation 1 and 2
x-y +x+y=4+32
2x=36
x=36/2=16answer
substituting value of y in equation 1
16-y=4
16-4=y

I legit do not know which it is.
Given:
The inequality is
[tex]c\leq 7[/tex]
Where, c is the number of cars in the parking lot.
To find:
The graph for the given inequality.
Solution:
We have,
[tex]c\leq 7[/tex]
Here, the value of c can be any real number less than or equal to 7. But c is the number of cars, so c must be a non-zero integer.
Since, all the non-zero integer values less than or equal to 7 are included in the solution set, therefore, c = 0,1, 2,3,4, 5,6,7.
In the graph of the given inequality, there are close circles on 0,1, 2,3,4, 5,6,7 as shown in option D.
Therefore, the correct option is D.

81.8181
Step-by-step explanation:
.......................
81.82% is the percentage of number 18 out of 22.
To find the percentage that 18 represents out of 22, you can use the following formula:
(18 / 22) × 100
Calculating this equation:
(18 / 22) × 100
1800/22
= 81.82
Therefore, 18 is approximately 81.82% of 22.

Write the point-slope form of the equation of the line that passes through the points (-8, 2) and (1, -4). Include your work in your final answer. Type your answer in the box provided to submit your solution.
Answer:
[tex]\displaystyle (y - 2) = -\frac{2}{3}\, (x + 8)[/tex].
Step-by-step explanation:
Given two points [tex](x_0,\, y_0)[/tex] and [tex](x_1,\, y_1)[/tex] on a line in [tex]\mathsf{2D}[/tex], the slope of that line would be:
[tex]\begin{aligned} m &= \frac{y_1 - y_0}{x_1 - x_0} \\ &= \frac{-4 - 2}{1 - (-8)} = -\frac{2}{3}\end{aligned}[/tex].
For a line with slope [tex]m[/tex] and a point [tex](x_0,\, y_0)[/tex], the point-slope equation of that line would be:
[tex]y - y_0 = m \, (x - x_0)[/tex].
It was already found that for this line, slope [tex]\displaystyle m = -\frac{2}{3}[/tex]. Take [tex](x_0,\, y_0) = (-8,\, 2)[/tex]. That is: [tex]x_0 = -8[/tex] and [tex]y_0 = 2[/tex]. Find the equation of this line in point-slope form:
[tex]\displaystyle (y - \underbrace{2}_{y_0}) = \underbrace{\left(-\frac{2}{3}\right)}_{m}\, (x - \underbrace{(-8)}_{x_0})[/tex].
Equivalently:
[tex]\displaystyle (y - 2) = -\frac{2}{3}\, (x + 8)[/tex].
