Answer:
6 yards long
Step-by-step explanation:
1/3 yards wide = 2 yards long
Let x = length of the other rug
1 yard wide = x yards long
1/3 : 2 = 1 : x
1/3 ÷ 2 = 1 ÷ x
1/3 × 1/2 = 1 / x
1/6 = 1/ x
Cross product
1*x = 6*1
x= 6 yards
Therefore, the length of the new rug with 1 yard wide is 6 yards long
The first thing to do is to find the ratio of wide to long of the two rugs by representing the long of the second rug with x

What is the total number of common tangents that can be drawn to the circles
Answer:
A. 0
Step-by-step explanation:
The circles are concentric. I.e there is no point where the circumferences of both circles ever touch each other. Hence there can be no tangent line possible that can be common to both circles at the same time.

In a survey, 200 people were asked if they smoke and whether or not they exercise regularly (more than twice a week). The results are summarized in the table
below
Answer/Step-by-step explanation:
a. % of people who smoke = no. of people who smoke ÷ total no. of people surveyed × 100
Total no. of people who smoke is given = 4 + 36 = 40
Total people surveyed = 200
% of people who smoke = [tex] \frac{40}{200}*100 = \frac{40}{2}*1 = 20 percent [/tex]
a. % of people who do not exercise regularly = no. of people who do not exercise regularly ÷ total no. of people surveyed × 100
Total no. of people who do not exercise regularly = 36 + 134 = 170
Total people surveyed = 200
% of people who smoke = [tex] \frac{170}{200}*100 = \frac{170}{2}*1 = 85percent [/tex]
What is (are) the solution(s) to the equation
2
(x−4)
2
=50
Answer:
x = 9 and x = -1
Step-by-step explanation:
This equation should be written all on one line:
2(x - 4)^2 = 50
using " ^ " to denote exponentiation.
Dividing both sides by 2 yields
(x - 4)^2 = 25
We must solve for x - 4, and then for x alone:
Taking the square root of both sides, we get:
x - 4 = ±5
which yields two separate solutions: x = 9 and x = -1

Drag equations to each row to show why the equation of a straight line is y = 3x, where 3 is the slope. Math item stem image
Answer:
Step-by-step explanation:
The question lacks appropriate diagram. Find the diagram attached.
Slope is the change in coordinate of the y coordinate to the x coordinate.
Mathematically, slope m = ∆y/∆x
From the diagram ∆y is the same as 3 (along the vertical) while ∆x is the same as 1 (along the horizontal)
m = ∆y/∆x = 3/1
∆y/∆x = 3/1
y/x = 3/1
Cross multiply
y × 1 = 3 × x
y = 3x
Hence the slope of the line is y = 3x
Answer:
you need to add the picture next time :)
Step-by-step explanation:
y/x=3/1 is the first blank
y=3x is the last one

Step-by-step explanation:
(27)
We can apply ratios to solve for the problem.
Let x be the missing value.
[tex]\displaystyle \frac{152}{4} =\frac{532}{x}[/tex]
Cross multiply.
152 × x = 532 × 4
152x = 2128
Divide both sides by 152.
x = 14
(29)
We can apply ratios to solve for the problem.
Let x be the missing value.
[tex]\displaystyle \frac{1}{6\frac{1}{4} } =\frac{\frac{2}{3} }{x}[/tex]
Cross multiply.
1 × x = 6 1/4 × 2/3
x = 6 1/4 × 2/3
Convert mixed fraction to improper fraction.
x = 25/4 × 2/3
x = 50/12
Simplify.
x = 25/6 or 4 1/6

Integrated math II
Answer:
[tex] \boxed{ \bold{ \sf{x = 16}}}[/tex]
[tex] \boxed{ \bold{ \sf{m < AFD = 82}}}[/tex]
Step-by-step explanation:
[tex] \sf{5x + 18 = 3x + 50}[/tex]
( Being vertically opposite angles)
Vertically opposite angles are always equal.
Move variable to L.H.S and change it's sign
Similarly, Move constant to R.H.S and change it's sign
⇒[tex] \sf{5x - 3x = 50 - 18}[/tex]
Collect like terms
⇒[tex] \sf{2x = 50 - 18}[/tex]
Subtract 18 from 50
⇒[tex] \sf{2x = 32}[/tex]
Divide both sides of the equation by 2
⇒[tex] \sf{ \frac{2x}{2} = \frac{32}{2} }[/tex]
Calculate
⇒[tex] \sf{x = 16}[/tex]
The value of x is 16
Now, let's find value of m<AFD :
[tex] \sf{m < afd + 5x + 18 = 180}[/tex] ( sum of angle in straight line )
plug the value of x
⇒[tex] \sf{m < AFD + 5 \times 16 + 18 = 180}[/tex]
Multiply the numbers
⇒[tex] \sf{m < AFD + 80 + 18 = 180}[/tex]
Add the numbers
⇒[tex] \sf{m < AFD + 98 = 180}[/tex]
Move constant to R.H.S and change it's sign
⇒[tex] \sf{m < AFD = 180 - 98}[/tex]
Subtract 98 from 180
⇒[tex] \sf{m < AFD = 82}[/tex]
Value of m<AFD = 82

In a small town, 68% of the people I need television, 72% owned radio, 12% owned neither television nor radio
Represent the information on a Venn diagram
What percentage of the population owned television only?
Answer:
The total of people is the 100%.
68% owns a tv.
72% owns radios.
12% does not own anything.
Now, if we add those, we have:
12% + 68% + 72% = 152%.
This is larger than the 100%, then this means that there is a percentage of people that have both Tv and Radio, this percentage is:
152% - 100% = 52%
We have a surpass because we are adding those 52% two times (because they belong in two different groups)
So, the table is:
68% owns a tv.
72% owns a radio.
12% does not own anything.
52% owns both, radio and tv.
68% - 52% = 16% owns only tv.
72% - 52% = 20% owns only radio.
Then the Venn diagram consist in two circles, one with the 72%, other with the 68%, in such way that the circles have an intersection of the 52%.
A fair die is thrown once.find the probability that an odd number appears?
Hi
on a regular dice you have 3 even number : 2 ;4;6
3 odd number : 1;3;5
so probability to have an odd number is : 3/6 = 1/2
Answer:
1/2
Step-by-step explanation:
On normal six-sided die, there are the numbers: 1, 2, 3, 4, 5, and 6.
The odd numbers are 1, 3, and 5.
There is a [tex]\frac{1}{6}[/tex] chance that you will roll any number specifically. Since you stated 3 numbers, the probability that you will roll any of those three numbers is [tex]\frac{3}{6}[/tex], which is equivalent to [tex]\frac{1}{2}[/tex].

solve 5(2+n)=3(n+6)
it’s for my AQR class
Answer:
n = 4
Step-by-step explanation:
We can expand, getting 10 + 5n = 3n + 18.
Then, combine all like terms, getting 5n - 3n = 18 - 10, which can be rewritten as 2n = 8.
Solve this by dividing both sides by 2, and get n = 4.
Answer: so its n=4
Step-by-step explanation: This problem will require distribution
5(2+n) = 3(n+6)
10+5n=3n+18
Move all the variables on one side
5n-3n=18-10
2n=8
Divide by 2
n=4
5 ( 2 + n ) = 3 ( n + 6 )
First distribute the 5 and the 3. By doing that, your equation should look like
10 + 5n = 3n + 18 Now, subtract 3n from both sides, this way all the " n " would be on the same side making it easier to solve
By subtracting 3n from both sides the equation would be
10 + 2n = 18 Now subtract 10 from both sides
By subtracting 10 from both sides your equation should be
2n = 8 Divide 2 from both sides
By dividing your equation should look like
n = 4 which is your answer

Determine the standard form of the equation of the line that passes through (-7, 8) and (0, 2)
Answer:
The answer is
[tex]y = - \frac{6}{7} x + 2[/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation we must first find the slope
Slope of the points (-7, 8) and (0, 2) is
[tex]m = \frac{2 - 8}{0 + 7} = - \frac{6}{7} [/tex]After that use the formula
y - y1 = m(x - x1)
To find the equation of the line
Equation of the line using point (0,2) and slope - 6/7 is
[tex]y - 2 = - \frac{6 }{7} (x - 0)[/tex][tex]y - 2 = - \frac{6}{7} x[/tex]We have the final answer as
[tex]y = - \frac{ 6}{7} x + 2[/tex]Hope this helps you

======================================================
Problem 1
Answer: 0-7+11 = 4
-----------------------------------
Explanation:
The bottom arrow is where we start. Specifically at 0 on the number line.
Then we move 7 units to the left. This is represented by -7 on the number line. So -7 is part of the addition equation.
Then we move 11 units to the right to arrive at 4 on the number line. This is the same as adding 11 to -7 to get -7+11 = 4 and that is the same as 0-7+11 = 4
======================================================
Problem 2
Answer: 1 + (-5) + 9 = 5
-----------------------------------
Explanation:
We now start at 1 on the number line. Move 5 units to the left to get to -4
Moving 5 units to the left is the same as subtracting 5, or adding on -5
So far we have 1 + (-5) which simplifies to -4
The last thing we do is add on 9 to go from -4 to 5. In other words, we move 9 units to the right when we go from -4 to 5
In terms of an equation, -4 + 9 = 5
So overall, that's how I got 1 + (-5) + 9 = 5
