Step-by-step explanation:
The age cullen is 5 yrs and Ada is 15 years old.
What is Algebra?Algebra is the part of mathematics that helps represent problems or situations in the form of mathematical expressions.
Given:
Cullen is 10 years younger than Ada.
The product of their ages 2 years ago was 39.
let the age of ada be x
Cullen's age = x- 10
22 years ago there age will be
Ada = x-22
Cullen = x-32
Now, the product of their age is 39
(x-2)(x-12)=39
x²-12x-2x + 24=39
x² -14x + 24=39
x² - 14x -15 = 0
x² -15x + x- 15=0
x(x-15) + 1(x-15)=0
(x-15)(x-1)=0
x= 15 or -1.
Hence, the age of Ada is 15 yrs and cullen age is 5.

:
Joe will go to the swimming pool on 20 different days this month.
• A one-day pass to the pool is $2.25.
• A monthly pass to the pool is $30.00.
How much money will Joe save by buying a monthly pass?
Answer:
He will save $15.00
Step-by-step explanation:
You multiply $2.25 by 20 days and that is equal to 45
So $45.00 - $30.00 that would be $15.00
If Joe buys a one-day pass for each of the 20 days he goes to the swimming pool this month, it will cost him $45.00. However, if he buys a monthly pass for $30.00, he will spend less money. Joe can save $15.00 by buying a monthly pass instead of a one-day pass each day.
Explanation:The subject of this question is mathematics as it involves arithmetic calculations to compare the cost of two possible options.
If Joe goes to the swimming pool 20 different days this month and buys a one-day pass for $2.25 every day, it would cost him 20 * $2.25 which equals to $45.00.
However, if Joe buys the monthly pass for $30.00, he would spend less money compared to buying a one-day pass every day. To find out how much Joe will save by buying the monthly pass, subtract the cost of the monthly pass from the total cost of buying one-day passes for 20 days. Therefore, $45.00 - $30.00 equals to $15.00.
So, Joe will save $15.00 by buying the monthly pass instead of a one-day pass each day he goes to the swimming pool.

Help me find the missing angles
Answer:
b) 105°
d) 130°
Step-by-step explanation:
An external angle has the same measure as the sum of the remote internal angles.
b) ? = 25° +80° = 105°
d) ? = 35° +95° = 130°
_____
This should be fairly obvious if you consider that the adjacent internal angle together with the external angle totals 180°, and the adjacent internal angle together with the other two internal angles totals 180°.
If the two "remote" angles are A and B, and the adjacent internal angle is C, then we have in symbols ...
A + B + C = 180° = ? + C
If we subtract C, then we find ...

c. Number of cancer cells over time with treatment.
d. rapid spread of disease.
3. Which table is an example of exponential growth? (SEE PICTURE)
a. fun island
b. Great island
c. mystery island
4. How can you determine if a table is a linear function or an exponential function?
1.
Answer: D) rapid spread of diseaseChoice A is not exponential growth or decay because the cost will go up by the same amount ($2) each time. Choices B and C are exponential, but they aren't growth functions. Rather, they are decay functions. A disease spreads exponentially because one person infects two, and then each of those two people infect two others (making 4 additional people infected), and so on.
===============================
2.
Answer: C) number of cancer cells over time with treatmentAssuming the treatment works and it is effective, then the cancer cells will go away over time. One example would be that the population is cut in half each time. Choice A is not an answer because the balance will go down the same amount each time. This is assuming the bus company does not change its prices. Choices B and D are eliminated because they represent growth.
================================
3.
I'm unable to answer this because the table is missing.
================================
4.
If the y values increase or decrease by the same amount, as x increases by some set amount, then you have a linear function. For example, if x increases by 1 pairs up with y increasing by 4, then the slope is 4/1 = 4 and we have a linear function.
--------
On the other hand, if x increases by 1 couples with the y values multiplying by some set amount, then you have an exponential function.
Example:
(x,y) = (1,2)(x,y) = (2,10)(x,y) = (3,50)Each time x increases by 1, y is multiplied by 5.
A semi-circle with a diameter of 4 is rotated around its diameter one full rotation, what is the volume of the solid generated by the revolution?
The volume of the solid generated by the revolution is 33.5 cubic units.
Step-by-step explanation:
It is given that, the diameter of the semi-circle is 4 and it is rotated to one full rotation around its diameter.
A solid generated when a semicircle is being rotated about its diameter is called a "SPHERE".
Therefore, the volume of the solid generated by the revolution is the volume of the sphere.
The formula for volume of the sphere is given by,
Volume of sphere = (4/3)πr³
where, r is the radius and π has the default value of 3.14
Here, the given diameter is 4.
To find the radius = diameter/2
radius = 4/2 = 2.
Now, to calculate volume of sphere substitute r=2 and π=3.14
volume of the sphere = (4/3)×3.14×2³
⇒ (4/3)×3.14×8
⇒ 100.48 / 3
⇒ 33.49 (approximately 33.5)
Therefore, the volume of the solid generated by the revolution is 33.5 cubic units.
The powers of 2 that are in the range 2 through 1,000 are 2, 4, 8, 16, 32, 64, 128, 256, and 512. Find all the powers of 3 that are in the range 3 through 1,000.
Final answer:
The powers of 3 that fall within the range of 3 through 1,000 are 3, 9, 27, 81, 243, and 729.
Explanation:
To find all the powers of 3 that are in the range 3 through 1,000, we need to calculate successive powers of 3 until the result exceeds 1,000. These calculations give us 31=3, 32=9, 33=27, 34=81, 35=243, 36=729, and 37=2187. However, since 2187 is greater than 1,000, we exclude it from our list. Therefore, the powers of 3 that fall within the specified range are 3, 9, 27, 81, 243, and 729.
111 = 14a This part is for the extra characters
The value of a = 7.93 or left as the fraction 111/14.
The question asks us to solve an algebraic equation for a single variable, specifically, solving 111 = 14a. This involves isolating the variable on one side of the equation to find its value. To do this, we divide both sides of the equation by 14, the coefficient of a.
Dividing both sides by 14, we get a = 111 / 14.
Thus, a = 7.928571429. However, for simplicity, we could round this to a = 7.93 or left as 111/14.

13. Your business needs to ship a package to another store. Company A charges $2.50 per pound plus a
$20 service charge. Company B charges $4.50 per pound without any service charge.
a. At what weight does it cost the same for both companies?
Solution:
Let "x" be the pounds
Company A charges $2.50 per pound plus a $20 service charge
Cost : 2.50x + 20 ------ eqn 1
Company B charges $4.50 per pound without any service charge
Cost : 4.50x ------- eqn 2
At what weight does it cost the same for both companies?
For both companies to cost the same, eqn 1 must be equal to eqn 2
2.50x + 20 = 4.50x
4.50x - 2.50x = 20
2x = 20
Divide both sides by 2
x = 10
Thus for 10 pounds, both companies cost the same
Kara rolled a number cube 10 times. The results of her rolls are shown
below.
1, 3, 3, 4, 6, 2, 2, 5, 3, 4
Based on Kara's results, what is the probability that her next roll
is either a 3 or 6?
Final answer:
The probability that Kara's next roll is either a 3 or a 6 is 1/3.
Explanation:
The question asks about the probability of rolling either a 3 or a 6 on a six-sided die based on previous rolls. The previous rolls are as follows: 1, 3, 3, 4, 6, 2, 2, 5, 3, 4. It is important to understand that each roll of a die is an independent event, meaning the outcome of one roll does not affect the outcomes of any other rolls.
Therefore, the results of Kara's previous rolls do not impact the probability of future rolls.
To determine the probability of rolling either a 3 or a 6, we consider that a six-sided die has six equally likely outcomes.
The probability of rolling a specific number, like a 3 or a 6, is therefore 1/6.
Since these are two separate outcomes, we add their individual probabilities to determine the probability of rolling either a 3 or a 6:
Probability of rolling a 3 = 1/6
Probability of rolling a 6 = 1/6
Total probability of either a 3 or 6 = 1/6 + 1/6 = 2/6 or 1/3.
Thus, the probability that Kara's next roll is either a 3 or a 6 is 1/3.
Solve the following equation 3+3x+9(9x)
I believe that the answer is 3+84x is this question wants you to simplify the expression.
Answer:
84x + 3
Step-by-step explanation:
3+3x+9(9x)
First 9 times 9x, which equals 81x
Then add the variables, so 3x + 81x and you get 84x
The equation is left as 84x + 3 because you can't add together a number with a variable and a number without a variable

The following table shows the number of goals that the Texas Sharpshooters scored in each of their 8 hockey games this season.
Based on this data, what is a reasonable estimate of the probability that the Texas Sharpshooters score exactly 1 goal next hockey game?
3, 4, 1, 4, 1, 1, 2, 1
Answer:
The probability that the Texas Sharpshooters score exactly 1 goal next hockey game is 0.5
Step-by-step explanation:
The topic in question is Experimental probability;
Experimental probabilities deal with the probability of an event happening based on past experiments.
Given
Number of observation, n = 8
To calculate an estimate of the probability that the Texas Sharpshooters score exactly 1 goal next hockey game, we need to count the total occurrence of 1 in the given data
Let p = total occurrence of 1
p = 4
The probability is then calculated as [tex]\frac{p}{n}[/tex]
by substitution;
Probability = [tex]\frac{4}{8}[/tex]
Probability = 0.5
Hence, The probability that the Texas Sharpshooters score exactly 1 goal next hockey game is 0.5
Which shows a difference of squares?
10y^2−4x^2
16y^4−x^2
8x^2−40x+25
64x^2−48x+9
A difference of squares must be a binomial, so we want two terms. This rules out the third and fourth options.
If we look at the first two, we must check that both terms are perfect squares.
Look at the first one: [tex]4x^2[/tex] is a perfect square (it's [tex](2x)^2[/tex]), but [tex]10y^2[/tex] is not a perfect square, because 10 is not a perfect square.
On the other hand, if we look at the second option, [tex]16y^4[/tex] is the square of [tex]4y^2[/tex], and [tex]x^2[/tex] is clearly the square of [tex]x[/tex]. So, this is the difference of two squares.
