Step-by-step explanation:
[tex] \frac{19695}{x - 15605} = 100[/tex]
[tex]19695 = 100(x - 15605)[/tex]
[tex]19695 = 100x - 1560500[/tex]
[tex]19695 + 1560500 = 100x[/tex]
[tex]15801 95 = 100x[/tex]
[tex] \frac{1580195}{100} = x[/tex]
[tex]x = 15801.95[/tex]
solve for x [tex]\sqrt7x-2=5[/tex]
Answer:
x=7
Step-by-step explanation:
1, Add 2 to both sides. This gives us [tex]\sqrt{7x} =7[/tex]
2. Square both sides. This gives us [tex]7x=49[/tex]
3. Divide both sides by 7. This gives us [tex]x=7[/tex]
A conference consists of 5 sessions: A, B, C, D, and E. Here are the costs of the sessions.
Session A: $50
Session B: $50
Session C: $100
Session D: $150
Session E: $200
Here is a graph of the cost of all 5 sessions.
A dotplot titled Graph A. A number line labeled session cost (dollars) goes from 40 to 200. 50, 2; 100, 1; 150, 1; 200, 1.
A participant plans to attend 3 sessions. Here is a list of all possible samples of size 3 sessions from this population of 5 sessions: ABC, ABD, ABE, ACD, ACE, ADE, BCD, BCE, BDE, and CDE.
Here is a graph displaying the minimum session cost for each possible sample of 3 sessions.
A dotplot titled Graph B. A number line labeled sample minimum session cost (dollars) goes from 50 to 100. 50, 9; 100, 1.
The participant chooses 3 sessions at random from the list of all 5 sessions. The result of the random selection is sessions B, D, and E.
Here is a graph displaying the distribution of session cost for this sample.
A dotplot titled Graph C. A number line labeled session cost (dollars) goes from 40 to 200. 50, 1; 140, 1; 200, 1.

Which of these graphs has its maximum point on the line x=3
Answer:
The last graph
Step-by-step explanation:
We are given two tips for finding our graph, it has a max point and the point of the line is x = 3. Meaning that this graph must open down and should not go anything further than 3 on the y graph.
The only one that fits this proposition is the last graph. Making it correct.
Answer:
see below
Step-by-step explanation:
To have a maximum, the parabola must be pointing down.
For the maximum to be at x=3, the vertex must have an x value at 3 and the line of symmetry must be 3

Step-by-step explanation:
Given expression: [tex]\sf (7 \times 10^5)^2[/tex]
Apply exponent rule [tex]\sf (ab)^2=a^2 \cdot b^2[/tex] :
[tex]\sf \implies 7^2 \times (10^5)^2[/tex]
[tex]\sf \implies 49 \times (10^5)^2[/tex]
Apply exponent rule [tex]\sf (a^b)^c=a^{bc}[/tex] :
[tex]\sf \implies 49 \times 10^{5 \cdot 2}[/tex]
[tex]\sf \implies 49 \times 10^{10}[/tex]
Scientific notation: [tex]\sf a \times 10^n[/tex]
where [tex]\sf 1\leq a < 10[/tex] and n is an integer
We can write 49 as [tex]\sf 4.9 \times 10=4.9 \times 10^1[/tex]
[tex]\sf \implies 4.9 \times 10^1\times 10^{10}[/tex]
Apply exponent rule [tex]\sf a^ba^c=a^{b+c}[/tex]

PLEASE HELP FOR EACH OF THE FIGURES, WRITE AN ABSOLUTE VALUE EQUATION
The solution set 0 and 8 are the true values of the absolute value equation
The absolute value equation that has the a solution set of 0 and 6 is |x - 3| = 3
How to determine the absolute value equation?From the figure, the solution sets of the absolute value equation are given as:
x = {0, 6}
Calculate the mean of the solution set
Mean = 0.5 * (0 + 6)
Mean = 3
Calculate the difference of the solution set divided by 2
Difference = (6 - 0)/2
Difference = 3
The absolute value equation is the represented as:
|x - Mean| = Difference
Substitute known values
|x - 3| = 3
Hence, the absolute value equation that has the a solution set of 0 and 6 is |x - 3| = 3

1. Her grandmother gave her $25 in a birthday card.
2. She earned $14 dollars babysitting.
3. She spent $10 on a ticket to the concert.

-$10
-$3
+$2
What are the signs to put in front of the amounts?When a person receives money, earns interst or his paid wages, the amount of money the person has increases. Thus, the sign to be used is the addition sign(+).
When a person pays for an item, donates to charity or loses money, the amount of money the person has reduces. Thus, the sign to be used is the subtraction sign (-).

The inequality to find the additional amounts x you can spend to get free delivery is 24.00 + x > y
How to determine the inequality?The given parameters are:
Small pizza = $4.50
Salad = $3.75
The cost of two small pizzas and four salads is:
Total = 2 * 4.50 + 4* 3.75
Evaluate
Total = 24.00
Let the amount to get free delivery be y.
