New grass seeds grow rapidly. A grass seed has grown to 12 millimeters tall. Tomorrow it will
be 23 millimeters tall, the next day it will be 34 millimeters tall, and on the next day it will be
45 millimeters tall. Write a rule to represent the height of the bean plant as an arithmetic
sequence. How tall will the plant be in 15 days?
A(n) = 16 + (n – 1)11; 194 millimeters
A(n) = 12 + (n – 1)11; 166 millimeters
A(n) = 13n; 195 millimeters
A(n) = 12n; 180 millimeters
Answer:
The correct answer is;
A(n) = 12 + (n-1)11; 166 millimeters
Step-by-step explanation:
Here, we want to write a rule representing the growth
From the question, we can see that the rate of growth is ;
34-23 = 23-12 = 11
This means it grows at a rate of 11 mm per day
So on the 15th day, its height will be;
We can have an arithmetic progression here, with 12 as the first term and 11 as the common difference
The nth term An can be represented as;
An = a + (n-1)d
where a = 12 mm , n = 15 and d = 11 mm
Thus, we have
An = 12 + (15-1)11
An = 12 + 154
An = 166 mm

Richard bought 3 pounds of bananas for $1.50. A banana weighs about 8 ounces and there are 16 ounces in a pound. At this rate, how many bananas can Richard buy for $5?
Answer:
Richard can buy 20 bananas for $5
Step-by-step explanation:
∵ Richard bought 3 pounds of bananas for $1.50
∵ 1 pound = 16 ounces
∴ 3 pounds = 3 × 16 = 48 ounces
→ That means Richard bought 48 ounces for $1.50
∴ The cost 48 ounces = $1.50
∵ A banana weighs about 8 ounces
→ Let us find 48 ounces equal to how many bananas
∵ 48 ÷ 8 = 6
∴ The 48 ounces are the weighs of 6 bananas
∴ The cost of 6 bananas = $1.50
→ To find how many bananas can he buy by $5, use the ratio method
→ Cost : Banana
→ 1.50 : 6
→ 5 : x
→ By using cross multiplication
∵ 1.50 × x = 5 × 6
∴ 1.50x = 30
→ Divide both sides by 1.50
∴ x = 20
∵ x is the number of bananas
∴ Richard can buy 20 bananas for $5

The average time a human being can hold their breath underwater is 1 minute. A hippo can hold its breath underwater for at least 5 times as long as a human. Write an inequality that represents how long a hippo can hold its breath underwater.
Answer:
Average breath hold time by hippo under water ≥ 5 minutes
Step-by-step explanation:
Average time by human = 1 minute
Average time by hippo = ≥ 5 times human
Since average human breath hold time = 1 minute
Average breath hold time by hippo = 5 * 1 minute
Average breath hold time by hippo under water ≥ 5 minutes

Answer:

Step-by-step explanation:
We are given:
Lateral surface area of a right circular cone : πr√r² + h²
From the question, we know that:
Lateral surface area = 236.64cm²
Radius = 4.75cm
Height = ?
Making h the subject of the formula
h = √[(A/r)² - πr²]/π
h = √[(236.64/4.75)² - π ×4.75²]/π
h = √(2481.9275169 - 70.882184247)/π
h = 15.12975 cm
Approximately to the nearest hundredth = 15.13cm
one baseball team played 24 games throughout their entire season if this baseball team won 6 of those games what percentage did they win
Answer:
25%
Step-by-step explanation:
As it states in the question there are 24 total games
So the denominator must be 24, The problem also states they won 6 games.
So the fraction of the games they won is 6/24.
But the qustion is not about the fraction, its about the percentage of the games they won.
so you can simplify 6/24 to 1/4 which eqeal to 25%
1/4=25%
So 25% is the answer.
A coach in a train can seat exactly 72 people for a trip. The train has 12 such coaches. If the train made 156 trips in full capacity in a year, how many people has it carried in that time?
72 x 12 = 864
864 x 156 = 134,784
in the capacity of the year, 134784 people have been carried on the train
merry christmas:)
In the word problem, the train has carried 134,784 people in that year.
How to Solve the Problem?To calculate the total number of people carried by the train in a year, we need to find the number of people carried in a single trip and then multiply it by the total number of trips made in a year.
Each coach can seat exactly 72 people, and there are 12 coaches on the train. So, in a single trip, the train can carry:
72 (people per coach) * 12 (number of coaches) = 864 people
Now, the train made 156 trips in full capacity in a year. So, the total number of people carried in that time would be:
156 (trips) * 864 (people per trip) = 134,784 people
Therefore, the train has carried 134,784 people in that year.

Tell whether the relation is a function.
Answer:
No, it is not a function
Step-by-step explanation:
Here, we want to tell if the relation is a function
For the relation to be a function, each independent variable must be mapped to only a single dependent variable
So what this means is that one term of the independent side must be mapped to one term of the dependent side
From the question, we can see that -10 and -15 were both mapped to -10 which should not be so
This means that the relation is not a function

Write the simplest polynomial function for each set of zeros
Zeros = -2, 5, -1
Answer:
The polynomial is ;
x^3 -2x^2 -13x - 10
Step-by-step explanation:
Given the zeros, we set them to equal zero so as to get the linear factors
Mathematically, that will be as follows;
x = -2
x + 2
x = 5
x-5
x = -1
x + 1
So we have the polynomial as;
(x + 1)(x + 2)(x-5)
= (x -5)(x^2 + 3x + 2)
= x^3+ 3x^2 + 2x -5x^2 -15x - 10
= x^3 -2x^2 -13x - 10

[tex]y+6 = -\frac{3}{4}(x-2)[/tex]
Step-by-step explanation:
Point-slope form of equation of a line is given by:
[tex]y-y_1 = m(x-x_1)[/tex]
Here m is slope of the line and (x1,y1) is the point from which the line passes.
Given
Slope = m = -3/4
Point = (x1,y1) = (2,-6)
We simply have to put these value into the general form of equation of line in point-slope form
[tex]y-(-6) = -\frac{3}{4}(x-2)\\y+6 = -\frac{3}{4}(x-2)[/tex]
Hence,
The right answer is Option 2:

A map has a scale of 4.5 inches=36 kilometers. If the distance between the two cities is 8.5 inches, what is the actual distance between the cities
9514 1404 393
Answer:
68 km
Step-by-step explanation:
Actual distance (d) will be proportional to the map distance.
d/8.5 = 36 km/4.5
d = (36 km)(8.5/4.5) = 68 km
The actual distance is 68 kilometers.

Mae Ling earns a weekly salary of $335 plus a 7.0% commission on sales at a gift shop. How much would she make in a work week if she sold $4,700 worth of merchandise?
Answer:
She made $664 during that work week.
Step-by-step explanation:
As Mae Ling earns $ 335 per week plus a commission of 7% with respect to the value of the sales she makes, and in the week she made sales for $ 4,700, to determine how much money she earned in the week the following calculation must be made:
335 + (4,700 x 7/100) = X
335 + (32,900 / 100) = X
335 + 329 = X
664 = X
Therefore, during that week Mae Ling earned $ 664.
