What is the number?
10% more than a number is 132.
Step-by-step explanation:
10% more = 110% of the number.
110% of the number = 132
100% of the number = 132 * (10/11) = 120.
The number is 120.

H(n)=-91\cdot\left(-\dfrac{1}{7}\right)^{\large{\,n-1}}h(n)=−91⋅(− 7 1 ) n−1 h, left parenthesis, n, right parenthesis, equals, minus, 91, dot, left parenthesis, minus, start fraction, 1, divided by, 7, end fraction, right parenthesis, start superscript, n, minus, 1, end superscript Complete the recursive formula of h(n)h(n)h, left parenthesis, n, right parenthesis.
Given:
[tex]h(n)=-91\cdot\left(-\dfrac{1}{7}\right)^{\large{\,n-1}}[/tex]
To find:
The recursive formula.
Solution:
We have,
[tex]h(n)=-91\cdot\left(-\dfrac{1}{7}\right)^{\large{\,n-1}}[/tex]
It is in the form of explicate formula of a GP, .i.e., [tex]a_n=ar^{n-1}[/tex].
Here, [tex]a=-91[/tex] and [tex]r=-\dfrac{1}{7}[/tex].
The recursive formula of a GP is
[tex]a_n=a_{n-1}\times r[/tex]
Using this the recursive formula for given problem is
[tex]h(n)=h(n-1)\times (-\dfrac{1}{7})[/tex]
Therefore, the required recursive formula is [tex]h(n)=h(n-1)\times (-\dfrac{1}{7})[/tex].

3. 'a' and 'b' are the intercepts made
by a straight-line with the co-
ordinate axes. If 3a = b and the line
pass through the point (1, 3), find
the equation of the line.
Given:
'a' and 'b' are the intercepts made by a straight-line with the co- ordinate axes.
3a = b and the line pass through the point (1, 3).
To find:
The equation of the line.
Solution:
The intercept form of a line is
[tex]\dfrac{x}{a}+\dfrac{y}{b}=1[/tex] ...(i)
where, a is x-intercept and b is y-intercept.
We have, 3a=b.
[tex]\dfrac{x}{a}+\dfrac{y}{3a}=1[/tex] ...(ii)
The line pass through the point (1, 3). So, putting x=1 and y=3, we get
[tex]\dfrac{1}{a}+\dfrac{3}{3a}=1[/tex]
[tex]\dfrac{1}{a}+\dfrac{1}{a}=1[/tex]
[tex]\dfrac{2}{a}=1[/tex]
Multiply both sides by a.
[tex]2=a[/tex]
The value of a is 2. So, x-intercept is 2.
Putting a=2 in [tex]b=3a[/tex], we get
[tex]b=3(2)[/tex]
[tex]b=6[/tex]
The value of b is 6. So, y-intercept is 6.
Putting a=2 and b=6 in (i), we get
[tex]\dfrac{x}{2}+\dfrac{y}{6}=1[/tex]
Therefore, the equation of the required line in intercept form is [tex]\dfrac{x}{2}+\dfrac{y}{6}=1[/tex].

Jude is going from his house to the library. He walks as a rate of 100 yards per minute and bikes as a rate of 300 yards per minute. On his way to the library, Jude walks for 12 minutes and then rides his bike the rest of the way. The library is 6000 yards from his house.
How many minutes did it take Jude to go from his house to the library?
22 Minutes
28 Minutes
30 Minutes
48 Minutes
Answer:
28 minutes
Step-by-step explanation:
100 yards times the 12 minutes he walked = 1200 yards. 6000-1200=4800
4800÷300=16
16 + 12 = 28
Answer:
28 Minutes
Step-by-step explanation:
The library is 6000 yd from the house.
He walks at a rate of 100 yd per minute for 12 minutes, which is 1200 yd of progress.
He bikes the rest of the 4800 yd on his bike at a rate of 300 yd per minute.
4800/300=16 minutes.
16+12=28 minutes.

Explain why the solution of 5x – 3 > 14.5 or 5 x minus 3 greater than 14.5 or StartFraction 2 x plus 5 over 3 EndFraction less than 4. < 4 has a solution of all real numbers, with one exception.
Answer:
There is no point where x = 3.5
Step-by-step explanation:
Given the inequality
5x – 3 > 14.5
We are to find the range of all values of x
Add 3 to both sides of the equation;
5x - 3 + 3 > 14.5+ 3
5x > 17.5
x > 17.5/5
x > 3.5
Also for the inequality;
[tex]\frac{2x+5}{3} <4\\[/tex]
Cross multiply;
[tex]2x+5 < 3(4)\\2x + 5 < 12\\[/tex]
Subtract from both sides;
[tex]2x + 5-5 < 12-5\\2x < 7\\x<7/2\\x<3.5[/tex]
The solution to both inequalities are x > 3.5 and x < 3.5. Since there is no point where x = 3.5, hence the solution will have solution on all real numbers except at x = 3.5
Answer:
When solving the first inequality, you get x > 3.5. When solving the second inequality, you get x < 3.5. The solution of an "or” compound in equality is everything in both solution sets, so the solution set is all of the numbers less than 3.5 and greater than 3.5. Since neither of the inequalities includes 3.5, the compound inequality has a solution of all real numbers except 3.5.
Step-by-step explanation:
Solve the inequality. Graph the solution. Describe the graph in the area provided. Be sure to indicate where there is an open or closed circle and what direction the number
line is shaded in. You can upload a picture of your work and explanation instead of

-27
12 (67– 12) or 315 – ) < 24
Step-by-step explanation:
The given inequality is :
[tex]-27\ge \dfrac{1}{2}(6x-12)[/tex]
Solving RHS of the inequality:
[tex]-27\ge \dfrac{1}{2}\times 2(3x-6)\\\\-27\ge (3x-6)[/tex]
Adding 6 both sides of the inequality
[tex]-27+6\ge (3x-6)+6\\\\-21\ge 3x\\\\x\le -7[/tex]
The attached figure shows the graph for the given inequality.

Find the inverse of f(x)=1/2x Write your answer in terms of g(x).
Answer:
The inverse of f is
[tex]g(x) = 2x[/tex]
Step-by-step explanation:
Given the function
[tex]f\left(x\right)=\frac{1}{2}x[/tex]
A function g is the inverse of function f if for y = f(x), x = g(y)
[tex]y=\frac{1}{2}x[/tex]
Replace x with y
[tex]x=\frac{1}{2}y[/tex]
Solve for y
[tex]y = 2x[/tex]
Therefore, the inverse of f is
[tex]g(x) = 2x[/tex]
A virtual reality headset lists for $719. Find the net cost after trade discounts if the series discount is 10/30.
Answer:
479.33
Step-by-step explanation:
10/30 is the same as 1/3 or 33.34%.
Multiply the fraction to the original price then subtract.
719 * 1/3 = 239.67
719 - 239.67 = 479.33

Kim finds a 1-meter tree branch and marks it off in thirds and fifths. She then breaks the branch along all the markings and removes one piece of every distinct length. What fraction of the original branch remains
Answer:
3/5
Step-by-step explanation:
We want to find the fraction of the original branch that remains, so we will assume a length of the branch in order to make our calculation easier.
Since Kim marks it off in thirds and fifths, let's find the least common multiple of 3 & 5.
Least common multiple of 3 & 5 is 15.
Thus,let's make the length of the branch to be 15-meter long.
Now, if the branch is 15 m long, considering the markings of thirds and fifths, the branch would be cut at:
3, 5, 6, 9, 10, 12 meters.
We are told that She then breaks the branch along all the markings and removes one piece of every distinct length. Thus;
Distinct lengths are;
3 metres
5 - 3 = 2 metres
10 - 9 = 1 meter
Total she removes = 3 + 2 + 1 = 6 meters.
Total remaining is;
15 - 6 = 9 meters
Expressing this as a fraction of the original branch gives:
9/15
Divide both numerator and denominator by 3 to get; 3/5
The areas of two rectangles can be represented by the functions shown. Which function represents the difference in the areas, h(x) = f(x) – g(x)? h(x) = 4x2 – 4x – 11 h(x) = 4x2 – 4x + 11 h(x) = –4x2 + 4x + 11 h(x) = 4x2 – 4x – 9
Answer:
x ^2 + 5xStep-by-step explanation:
Let the area of the two triangles be expressed as;
f(x)= 4x^2+6x
g(x)=3x^2-x
Taking the difference
h(x) = f(x) - g(x)
h(x) = 4x ^2+6x - 3x^2-x
Collect like terms'
h(x) = 4x ^2 - 3x^2+6x-x
h(x) = x ^2 + 5x
Hence the difference is x^2 + 5x
Note that the functions were assumed. The same methos can be applied to any other given functions.
Answer:
B: h(x) = 4x2 – 4x + 11

Answer:
Step-by-step explanation:
I feel like there are many ways to begin this problem, but I'd distribute the 2(x+7) so that you are left with 2x+14. This way you can add 2x and 3x and subtract 14 to the other side.
