Anya walked 7/10 km to the bank and then walked 3/4 km to the flower shop. What is the total distance Anya walked? Show your work. Write your answer as a mixed number.
Answers
Answer:
1 and 9/20
Step-by-step explanation:
add your fractions together 7/10 + 3/4
make them have the same denom 14/20 + 15/20
so its 29/20
to get the mixed fraction, divide 29/20 to get 1.45. The 1 is your whole number. Subtract 20 from 29 to get 9, which is what is remaining, and will go over 20.
the answer is 1 and 9/20
work:
7/10km = 14/20km
3/4km = 15/20km
15/20+14/20=29/20km
29/20 as a mixed number is 1 and 9/20.

undefined slope
Step-by-step explanation:
This is a vertical line parallel to the y- axis.
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 5, - 3) and (x₂, y₂ ) = (- 5, - 6) ← 2 points on the line
m = [tex]\frac{-6+3}{-5+5}[/tex] = [tex]\frac{3}{0}[/tex]
Since division by zero is undefined then the slope is undefined.
Note that all vertical lines have an undefined slope

Erica’s bank account increased from $1,200.00 to $1,500.00. By what percent did the amount of money in her bank account increase?
Answers
25% amount of money increased in her bank account.
Here,
Erica’s bank account increased from $1,200.00 to $1,500.00.
We have to find the percent of amount of money in her bank account increase.
What is Percent?
Percentage is a fraction or a ratio in which the value of whole is always 100.
Now,
Erica’s bank account increased from $1,200.00 to $1,500.00.
Increased money = $1,500 - $1,200 = $300
Percentage of increased money = [tex]\frac{300}{1200} * 100 = 25[/tex]
Hence, 25% amount of money increased in her bank account.

The store bought a table for $200, and sold it for $350. What percentage was the markup? %
Answers
Answer: 175% or 75% more in price
Step-by-step explanation:
There was a 75% of markup in the price.
What is percentage?A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction.
Given that, The store bought a table for $200, and sold it for $350, we need to find the percentage of markup in the price,
percentage of markup in the price =
(final price - original price)/(original price)x100
final price = $350, original price = $200
Markup in price = $350-$200 = $150
percentage of markup in the price = 150/200x100 = 75%
Hence, There was a 75% of markup in the price.

If the point (2+c,y) is on the graph of f(x), the following point will also be on the graph of f(x):
A) (c-2,y)
B) (2-c,y)
Answers
Step-by-step explanation:
point (c-2, y) lies on the graph of f(x)=x(x-4)f(x)=x(x−4) .
Step-by-step explanation:
Given function f(x)=x(x-4)f(x)=x(x−4) also point (2+ c,y) is on the graph of f(x) ,
We have to find out of given point which point will also be on the graph of f(x).
Consider the given function f(x)=x(x-4)f(x)=x(x−4)
f(x)=x(x-4)f(x)=x(x−4) can be rewritten f(x)=x^2-4xf(x)=x
2
−4x
Now we substitute the given point (2+ c, y) in the function given ,
we have,
f(x)=y=x(x-4)f(x)=y=x(x−4)
put for x as 2+c , we have,
\Rightarrow y=(2+c)(2+c-4)⇒y=(2+c)(2+c−4)
Solve, we get
\Rightarrow y=(2+c)(c-2)⇒y=(2+c)(c−2)
Thus, both point (2+c, y) and (c-2, y) lies on the graph of f(x)=x(x-4)f(x)=x(x−4)
Thus, option (1) is correct.

Which represents the inverse of the function f(x) = 4x?
h(x) = x + 4
h(x) = x – 4
h(x) = three-quartersx
h(x) = one-quarterx
Answers
By definition, the correct answer is the last option: the inverse of the function f(x) = 4x is h(x)= [tex]\frac{1}{4}[/tex]x.
Definition of inverse functionThe inverse or reciprocal function of f(x) is called another function f⁻¹(x) that satisfies: If f(x)=y , then f⁻¹(y)=x.
To build or calculate the inverse function of any function, one of the ways to do it is to interchange the variables x and y, and use a combination of algebraic methods in order to isolate the variable "y".
Inverse of f(x)=4xBeing f(x)=y=4x, to calculate the inverse, in first place you interchange the variables x and y:
f(y)=x=4y
Isolating the variable y, you get:
h(x)=x÷4= [tex]\frac{1}{4}[/tex]x
Finally, the correct answer is the last option: the inverse of the function f(x) = 4x is h(x)= [tex]\frac{1}{4}[/tex]x.

A mosquito is walking at random on the nonnegative number line. She starts at $1$. When she is at $0$, she always takes a step $1$ unit to the right, but, from any positive position on the line, she randomly moves left or right $1$ unit with equal probability. What is the expected number of times the mosquito will visit $0$ before the first time she visits $4$?
Answers
The expected number of times the mosquito will visit 0 before the first time she visits 4 is 3/4 by using concept of probability and geometric series.
Given that repeatedly throwing a fair tetrahedral die, trying to get a 4 (success) before getting a number from 1 to 3 (failure), which follows a geometric distribution.
To find the expected number of visits to 0 before reaching 4, analyze two cases:
success (reaching 4 before 0) and failure (reaching 0 before 4).By the given data, the probabilities of two cases are:
P(success) p = 1/4,
P(failure)=3/4.
The expected count of failures, X, can be found in terms of success probability p as
[tex]E[X]=\sum_{x=0}^{+\infty}[x(1-p)^xp][/tex]
On substituting p = 1/4 gives:
[tex]E(X) = 0(1/4)+1(3/4)(1/4)+2(3/4)^2(1/4)+3(3/4)^3(1/4)+.........[/tex]
On taking (1/4) gives
[tex]E(X) = 1/4[3/4+(3/4)^2+(3/4)^3+......+\infty]----(1)[/tex]
Consider [tex]3/4+(3/4)^2+(3/4)^3+......+\infty[/tex]
This forms a geometric series tends to infinity and the sum is given by :
[tex]S_\infty = a/(1-r)[/tex]
Here: a= 3/4
r = 3/4
Plugging these values into formula gives:
[tex]3/4+(3/4)^2+(3/4)^3+......+\infty = S_\infty[/tex]
[tex]S_\infty= 3/4/(1-3/4)[/tex]
On subtracting the denominator gives:
= 3/4/(1/4)
On taking reciprocal gives:
= 3/4 * 4
On simplifying gives:
= 3
Substituting these value into given equation 1 gives:
E(X) = 1/4*[3]
On multiplying gives:
E(X) = 3/4.
Therefore, the expected number of times the mosquito will visit 0 before the first time she visits 4 is 3/4 by using concept of probability and geometric series.

An algebra class normally has y students, but today it is just 2/3 full. Express the number of students in class today terms of y.
Answers
Answer:
2/3y
Step-by-step explanation:
If the class usually has y students and has 2/3 today, it can be represented by 2/3y.
Since multiplying a number or variable by 2/3 makes it 2/3 of the amount, 2/3y will represent the people in the class.
So, in terms of y, 2/3y represents the number of students in class today.
