There were 24 boys and 20 girls in a chess club last year. This year
the number of boys increased by 25% but the number of girls
decreased by 10%.
Find the overall percent change in membership of the club.
10
Answer:
35%
Step-by-step explanation:
If you take the amount of percent the girls decreased, and the amount the boys increased in percentages, you will have your answer when just adding them together. So the answer is 35% or as in 6 boys joined and 2 girls left. So that gives you a total of 8 joining or leaving the chess club or 35% difference.

Step-by-step explanation:
Mr. Borden was given a $50 gift card to use at the bowling alley. It costs him $10 per night to bowl. Each time he goes to the bowling alley he records the amount he has used and the amount he has left. If x is the number of nights bowled, b(x) is the balance on the gift card. Discreet
Answer:
He initially has $50 on his card.
For each night that he goes to play, $10 are discounted from the card, then if he went x nights to play, the amount of money that there is in the card is:
b(x) = $50 - $10*x
Now, notice that x must be a whole number because this measures the number of nights that he went to play, and we can not have rational numbers to describe this.
Then the domain of this function will be discrete (and this implies that the range must also be discrete)
Where the possible values of x are:
{0, 1, 2, 3, 4, 5}
(after x = 5, there is no more money in the card)
And the possible values of b(x) are:
{$0, $10, $20, $30, $40, $50}
what reasons can be used to justify statement 4 in the proof above?

The drawing at the right shows a person,
5 feet tall, casting a shadow 3 feet long.
The tree is casting a shadow 15 feet long.
How tall is the tree?
Answer:
I would say the tree is 18 feet tall
Answer: 25 feet tall
Step-by-step explanation:
First, let's take a look at the person. If they are 5 feet tall and cast a shadow of 3 feet, we can easily convert this into a proportion: 5 feet tall: 3 feet shadow.
Continuing with this method, we can convert the tree into a proportion: x feet tall: 15 feet shadow.
So, 5:3=x:15. Mathematically, think of it as 5/3=x/15.
To find x, you will need to multiply 15 to both sides, or perform cross multiplication. (5/3)(15)=(x/15)(15). This will equal 25. The tree is 25 feet tall.

suppose aaron earned 15.75 in interest for account A and 28.00 in interest for account B after 21 months if the simple interest rate is 3.0% for account A and 4.0% for account B wich account has the greater principle explain
Answer:
Principle for account B is greater.
Step-by-step explanation:
First of all, let us have a look at the formula for Simple Interest:
[tex]SI =\dfrac{PRT}{100}[/tex]
Where [tex]P[/tex] is the principle amount
[tex]R[/tex] is the Rate of interest per annum
[tex]T[/tex] is the time in years.
Time = 21 months = [tex]\frac{21}{12}\ yrs[/tex]
[tex]R_1 = 3\% \\R_2=4\%[/tex]
Let the Principles be [tex]P_1, P_2[/tex].
Using the formula for Simple Interest, we get:
[tex]SI_1=\dfrac{P_1\times 3\times 21}{100\times 12}\\\Rightarrow 15.75=\dfrac{P_1\times 3\times 21}{100\times 12}\\\Rightarrow P_1 = 300[/tex]
[tex]SI_2=\dfrac{P_2\times 4\times 21}{100\times 12}\\\Rightarrow 28=\dfrac{P_2\times 3\times 21}{100\times 12}\\\Rightarrow P_2 = 533.33[/tex]
Therefore, principle for account B is greater.

1. Solve for q:
√3q + 2 = √5
2. solve for d:
4d + 1 = √3
3. Solve for m:
m/√3 - 11 = 4
Answer:
1) q = (sq rt 15 - 2) / 3
2) d = (sq rt 3 - 1) / 4
3) m = 15 * sq rt 3
Step-by-step explanation:
1.√3q + 2 = √5
we bring to the power of 2 each element
(√3q)^2+2^2=√5^2
3q+4=5
3q=4-5
q=1/3
2.
4d+1=√3
we do the same thing
16d^2+1=3
16d^2=2
d^2=2/16
d^2=1/8
d=√1/√8
3.
m/√3 -11=4
first we rationalise by multiplying the first fraction with √3
m√3 /3-11=4
now we can bring to the power of 2
3m^2/9-121=16
3m^2/9=137
m^2/3=137
m^2=411
m=√411
The graph for the equation y = 2 x minus 2 is shown below. On a coordinate plane, a line goes through points (0, negative 2) and (1, 0). If another equation is graphed so that the system has one solution, which equation could that be? y = 2 (x + 1) y = 2 (x minus 1) y = 2 (x minus 2) y = negative 2 (x + 1)
THIS IS TIMED
Answer:
i think it is b correct me if i am rong
Step-by-step explanation:
The correct equation for the solution to be one will be y = 2(x -1) hence, the correct option is (B).
What is a graph?The link between lines and points is described by a graph, which is a diagrammatic representation of a network. A graph is made up of some points and the distance between two. It doesn't matter how much time the lines are or where the points are located. A node is a name for each constituent in a graph.
For example to draw the equation y = 2x +9 this will draw a straight line in the coordinate geometry.
Given that an equation y = 2x - 2 now another equation draw which should intersect with the line y = 2x - 2 at a single point only so that the system has only one solution.
so the y = 2x - 2 should be matched with any one option.
By cross-checking the option it will be (B) with equation y = 2(x -1).

1: A man owns 50 shares of stock worth $30 each. The corporation declared a dividend of 6% payable in stock. How many shares did he then own?
Answer:
53 shares
Step-by-step explanation:
Calculation for how many SHARES did he then own
Using this formula
Numbers of shares=[ (Dividend percentage payable in stock ×Shares of stock)+Shares of stock]
Let plug in the formula
Numbers of shares= [(.06 x 50 shares)+50 shares]
Numbers of shares= 3 + 50 shares
Numbers of shares = 53 shares
Therefore How many shares did he then own is 53 shares

Consider the following system of equations
-2x+5y=19
Y=-5/6x-1/6
Use this graph of the system to approximate its solution
A. (13/4,-5/2)
B. (-5/2,13/4)
C. (-13/4,5/2)
D.) (5/2,-13/4)
Answer:
C
Step-by-step explanation:
We have the system of equations:
[tex]\displaystyle -2x+5y=19 \\\\ y=-\frac{5}{6}x-\frac{1}{6}[/tex]
And we want to use the graph to approximate the solution to the system.
Remember that, graphically, the solution to a system of equations is where the two graphs intersect.
We can see that the point at which the two lines intersect is in QII.
Hence, x is negative and y is positive.
The only choices that satisfies these conditions are B or C.
However, for B, -5/2 is -2.5. As we can see from the graph, the x-coordinate of the point of intersection is less than -3.
Hence, the only choice left is C. -13/4 also is -3.25, fulfilling our condition.
So, our final answer is C.
At an intersection, the red light of route A is red for 60 seconds and the other two lights are red for 45 and 75 seconds, respectively. What is the probability that a car traveling from route A will encounter a red light at an intersection?
Answer:
1/3
Step-by-step explanation:
The probability of an event E in a sample space S is P(E) = desired outcome/total number of possible outcomes.
The probability of encountering a red light at the intersection P(red light on) = time it takes red light to stay on/total time all the lights stay on, where desired outcome = time it takes red light to stay on on route A and total number of possible outcomes = total time all the lights stay on.
Since all the other two lights have to come on after the red light goes off and before the red light comes on again, and the red light has to be on to encounter it at an intersection.
So, P(red light on) = 60 s/(60 s+ 45 s+ 75 s)
= 60 s/180 s
= 1/3
