Anna buys 24 seeds and plants 3 in each pot. She has 5 pots. How many more pots does Anna need to plant all of her seeds
The number of pots required to plant 24 seeds will be 8.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Given that Anna buys 24 seeds and plants 3 in each pot. She has 5 pots.
The number of the pots will be calculated as Anna needs 3 more pots. 3 times 5 is 15 seeds. And she has 24 seeds. so 24 divided by 3 is 8. 8 minus 5 is 3.
Number = 24 / 3 = 8 pots
Therefore, the number of pots required to plant 24 seeds will be 8.

estimate the value of 98.5*13
To estimate the value of 98.5*13, you round 98.5 to 100 and 13 to 10, and then multiply to get an estimated product of 1000, which is a simple calculation that provides a close approximation to the precise answer of 1,280.5.
To estimate the value of 98.5*13, you can round 98.5 to the nearest ten and 13 to the nearest ten. So, 98.5 is approximately 100 and 13 is approximately 10. To estimate the product, you multiply these two numbers:
100 * 10 = 1000
The estimated value of 98.5*13 is therefore around 1000. The calculator gives 1,280.5 as the precise answer, but our estimate simplifies the calculation while providing a close approximation.

Which is a better estimate for the length of an ironing board?
A better estimate for the length of an ironing board would be 120 inches, or 10 feet. This exercise illustrates the importance of carefully calculated approximations rather than relying on rough 'guesstimates'.
Explanation:A better estimate for the length of an ironing board would be 120 inches, or 10 feet. This estimate is closer to the final approximate value mentioned in the discussion. However, the early estimate of 3 inches was significantly off. This exercise illustrates the importance of carefully calculated approximations rather than relying on rough 'guesstimates'.

Write an equation for a rational function with:
Vertical asymptotes at x = 3 and x = -4
x intercepts at x = -1 and x = 5
Horizontal asymptote at y = 6
Final answer:
A rational function with vertical asymptotes at x = 3 and x = -4, x-intercepts at x = -1 and x = 5, and a horizontal asymptote at y = 6 is constructed by using factors that make the denominator zero at the vertical asymptotes and the numerator zero at the x-intercepts, with a constant ratio to define the horizontal asymptote.
Explanation:
To construct a rational function that meets the specified criteria, we need to ensure that the function has the correct vertical and horizontal asymptotes as well as the specified x-intercepts. A vertical asymptote occurs where the denominator of the rational function is equal to zero, whereas x-intercepts occur where the numerator is equal to zero.
The horizontal asymptote represents the end behavior of the function as x approaches infinity.
Step-by-step construction of the rational function
For vertical asymptotes at x = 3 and x = -4, the denominator must be zero at these points. So, we can use factors (x - 3) and (x + 4) in the denominator.
For x-intercepts at x = -1 and x = 5, the numerator must be zero at these points. Thus, we can use factors (x + 1) and (x - 5) in the numerator.
To incorporate a horizontal asymptote at y = 6, we need the degrees of the numerator and denominator to be the same, and the leading coefficients must have a ratio that equals 6. To achieve this, we introduce the constant 6 in the numerator.
The resulting rational function, considering all the conditions above, is:
f(x) = 6(x + 1)(x - 5) / ((x - 3)(x + 4))

Jimmy made a 15% profit on the sale of a custom designed boat, and the original cost of the boat was $15,000. The boat sold for how much?
Answer:
the boat was sold for $17,250
Step-by-step explanation:
Jimmy made a 15% profit, that means that the 15% of the cost is going to be his profit, so the 15% of $15,000 is:
$15,000(0.15)= $2,250
If his profit is 2,250, the price of the boat is going to be the initial cost plus the profit. So:
Price=$15,000 + $2,250 = $ 17,250
Then, the boat was sold for $17,250
Using proportions and the profit concept, it is found that the boat sold for $17,250.
This question is solved by proportions, using a rule of three.Profit of 15% means that the sales price was 15% more than the original cost. Thus, the original cost of $15,000 is worth 100% = 1, while the sales price of x is worth 100% + 15% = 115% = 1.15.The rule of three is:
$15,000 - 1
$x - 1.15
Applying cross multiplication:
[tex]x = 15000(1.15) = 17250[/tex]
The boat sold for $17,250.

Wally is playing with his toy robot. The robot's battery is 80% full when he starts playing with it. The battery drains to 74% after Wally plays with the robot for 40 minutes. If t represents the time elapsed in minutes and l represents the battery level, which of the following equations can be used to model this situation?
A. l = -0.15 + 80t
B. l = -0.15t + 80
C. l = 80t + 0.15
D. l = -0.15t - 80
Answer:
B. l = -0.15t + 80
Step-by-step explanation:
From the options we can see that the relation between the battery level (I) and the time elapsed (t) is modeled by the equation of a line, that is:
I = a*t + b
where a and b are some constants, I is in % and t is in minutes.
At t = 0 (when Wally starts to play) the battery is 80%, that is:
80 = a*0 + b
80 = b
At t = 40 minutes the battery is 74%, then:
74 = a*40 + 80
74 - 80 = a*40
-6 = a*40
-6/40 = a
-0.15 = a
Then, the equation is I = -0.15*t + 80
Five classmates came to Dan’s birthday party. This is half as many as the number of his summer camp friends who came and one third of the number of his relatives that came. How many people were at Dan’s birthday party?
The total number of people that attended dan's birthday party is;
30 People
We are told that 5 classmates attended dan's birthday party.
Number of classmates at birthday party = 5
We are told that this 5 people is only half of his summer camp friends that attended the birthday party.
Thus, number of summer camp friends that attended = 5 × 2 = 10
Similarly the 5 people is only a third of his relatives that attended the birthday party.
Thus, number of relatives that attended = 5 × 3 = 15
Therefore,
total number of people that attended dan's birthday party = 5 + 10 + 15 = 30 people

m∠4 = 105° and m∠6 = 50°.
m∠2 =
50°
55°
75°
Answer:
x = 55°
Step-by-step explanation:
<4 = 105
<4 + <3 = 180 (supplementary angles, form a line)
180-105= 75
<3 = 75
The interior angles of a triangle always equal 180 degrees.
<3 = 75 degrees, <6 = 50, <2 = x
75+50+x = 180
125 + x = 180
x = 55°

I’m not sure how to “explain your math thinking”.
Answer:
9 + 7 = 16Step-by-step explanation:
The math thinking refers to the process you did to solve the sum 9 + 7.
To solve this we could think the following process:
1. We complete the first number to 10.
2. The completion subtracted one unit from 7, so now it's 6.
3. Then we sum the ten and the six, it's easier to operate with tens.
Therefore, the answer is 16.
Remember that not everyone solve math problems and exercises the same way, because we all are different from each other.
