Esther had five times as many cards as Richard. Esther gave 1/4 of her cards to Richard. Then, Richard gave 1/6 of his cards to Esther in return. In the end, Esther had 90 more than Richard. How many cards did Esther have at first?
Answer:
Esther has 200, Richard has 40
Esther gives Richard 50 cards. Now they have
Esther: 150, Richard: 90
Richard gives Esther 15, so they now have
Esther: 165, Richard 75
Step-by-step explanation:
Answer:
Esther had 200 cards at first
Step-by-step explanation:
Variables:
Esther: 5r
Richard: r
Equalities:
e = 5r
e - e/4 + 1/6 (r + e/4) = 5/6 (r + e/4) + 90
Solve:
Replace e with 5r and solve for r:
e - e/4 + 1/6 (r + e/4) = 5/6 (r + e/4) + 90
5r - 5r/4 + 1/6 (r + 5r/4) = 5/6 (r + 5r/4) + 90
5r - 5r/4 + 1/6 (2.25r) = 5/6 (2.25r) + 90
5r - 1.25r + 0.375r = 1.875r + 90
5r - 1.25r + 0.375r - 1.875r = 90
2.25r = 90
r = 40
Esther: 5r = 5(40) = 200
Richard: r = 40

-5x + y = -6
7x + 2y = 39
Answer:
x=3, y=9
Step-by-step explanation:
Mulriplying the first equation by 2 yields -10x+2y=-12.
Subtracting the second equation from this gives -17x=-51, and thus x=3.
Substituting this back into the first equation gives -15+y=-6, and thus y=9.
A basketball player makes 65% of all free throws
in her first 5 seasons. In her 6th season she
makes 105 out of 150 free throws. How does the
observed frequency of her 6th season compare
to the expected frequency? Provide a possible
explanation for any similarities or differences in
the frequencies. 7.50.3.7
Answer: The relative frequency of an event is the ratio of the number of times an event happens to the number of times the event is attempted. Relative frequencies are often used in decision making and to predict outcomes. Relative frequencies are based on data previously collected and recorded. Probabilities are based on assumptions.

What is the approximate circumference of the circle shown below?
A. 37.8 cm
14.8 cm
B. 46.5 cm
C. 23.2 cm
D. 92.9 cm
SUBMIT
The approximate circumference of the circle shown in the image is given as follows:
B. 46.5.
How to obtain the circumference of a circle?The circumference of a circle of diameter d is given by the multiplication of π and the diameter, as follows:
C = πd.
π has the numeric value of 3.14, hence the equation is approximated as follows:
C = 3.14d.
The diameter of a circle is the distance between two points on the circumference of the circle that pass through the center, hence for this problem it is given as follows:
d = 14.8 cm.
Then the circumference of the circle is of:
C = 3.14 x 14.8
C = 46.5 cm.

What is log4 (5x+2) = 5x in exponential form?
Answer:
4^(5x) = 5x + 2
Step-by-step explanation:
Applying the definition of logarithm we can say that if logb(x) = y, then b^y = x;
Accordingly your equation log4 (5x+2) = 5x in exponential form should be 4^(5x) = 5x + 2

Describe what is happening in this graph with regards to the number of people in an amusement park on a summer day.
Answer:
The number is gradually increasing representing the people entering the park, the number becomes constant after a while , and lastly the people are starting to leave causing the decline on the graph.
Step-by-step explanation:
This the plebian explanation of how my teacher it.
The graph is showing the entry of the people in the amusement park.
What is a graph?A graph represents the data on the vertical and horizontal coordinates so we can see the trend of the data.
A graph is a structure that resembles a set of items in mathematics, more specifically in graph theory, in which some pairings of the objects are conceptually "connected."
The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.
As more people visit the park, the number progressively rises; after a while, it stabilizes; and finally, as more people start to leave, it begins to drop on the graph.
Therefore, the graph is showing the entry of the people in the amusement park.

A price was first decreased by 12%, they it was decreased again by an additional 5%. What is the percent of the total de. ease?
9514 1404 393
Answer:
16.4%
Step-by-step explanation:
Assuming the 5% was taken off of the already-discounted price, then the original price was multiplied by ...
(1 -12%)(1 -5%) = 0.88×0.95 = 0.836 = 1 -16.4%
The total decrease was 16.4%.
The original price of a pair of headphones is $39.99 before tax. When David bought the headphones they rang up for $31.99 before tax. He
then paid 6% sales tax on the discounted price.
Part A: What is the percent discount on the headphones? Show all work and steps in your solution. (5 points)
Part B: What is the total amount that Dalton paid for the headphones including tax? Show all work and steps in your solution. (5 points)
Answer:
To find the sales tax multiply the purchase price by the sales tax rate. Remember to convert the sales tax rate from a percent to a decimal number. Once the sales tax is calculated, it is added to the purchase price. The result is the total cost—this is what the customer pays.
