Plant A is 4 inches tall and growing at a rate of 4 centimeters per
week. Plant B is 10 inches tall and growing at a rate of 1 centimeter per
week. After how many weeks will both plants have the same height?
Choose the equation that best represents this situation.
A.) 4 - 4y = 10 - Y
B.) 4 + 4y = 10 + y
C.)4 + y + 4y = 10
D.)4(y + 4y) = 10
Answer:1/2t + 4 = 1/4t + 5.5
1/2t - 1/4t = 5.5 - 4
2/4t - 1/4t = 1.5
1/4t = 1.5
t = 1.5 x 4
t = 6
h = 1/2t + 4
h = 1/2(6) + 4
h = 3 + 4
h = 7
solution is (7,6)
means that the plants will both be 7 cm tall after 6 weeks

Which one would the equation be?
Answer:
a. [tex] y = \frac{2}{5}x - 6 [/tex]
Step-by-step explanation:
The slope-intercept form of equation of a line is given as [tex] y = mx + b [/tex]. Where,
m = slope
b = y-intercept.
Rewrite the equations, [tex] 2x - 5y = 12 [/tex] and [tex] 4y + 24 = 5x [/tex], in the slope-intercept form by making y the subject of the formula. Then, derive our new equation that has the same slope as the first equation, and the same y-intercept as the second equation.
[tex] 2x - 5y = 12 [/tex]
[tex] 2x - 12 = 5y [/tex]
Divide both sides by 5
[tex] \frac{2x - 12}{5} = \frac{5y}{5} [/tex]
[tex] \frac{2x}{5} - \frac{12}{5} = y [/tex]
Rewrite
[tex] y = \frac{2x}{5} - \frac{12}{5} [/tex]
The slope of [tex] 2x - 5y = 12 [/tex] is ⅖.
[tex] 4y + 24 = 5x [/tex]
[tex] 4y = 5x - 24 [/tex] (subtraction property of equality)
Divide both sides by 4
[tex] \frac{4y}{4} = \frac{5x - 24}{4} [/tex]
[tex] y = \frac{5x}{4} - \frac{24}{4} [/tex]
[tex] y = \frac{5x}{4} - 6 [/tex]
The y-intercet of [tex] 4y + 24 = 5x [/tex] is -6
Therefore, the equation that has the same slope as the first equation and the same y-intercept as the second equation would be:
[tex] y = mx + b [/tex]
Plug in the values of m and b
[tex] y = \frac{2}{5}x + (-6) [/tex]
[tex] y = \frac{2}{5}x - 6 [/tex]

A florist sells a dozen roses for $35.40. She sells individual roses for the same unit cost. Write an equation to represent the relationship between the number of roses, x, and the total cost of the roses, y. How much would 18 roses cost?
Answer: The equation is
The cost of 18 roses is 53.10.
Step-by-step explanation:
Given:
A florist sells a dozen roses for 35.40. She sells individual roses for the same unit price.
Now, to find the cost of 18 roses and write an equation to represent the relationship between the number of roses, x, and the total cost of the roses, y.
1 dozen = 12.
Now, to get the cost of 18 roses we use unitary method:
If 12 roses cost = 35.40.
So, 1 roses cost = 2.95.
Thus, 18 roses cost = 53.10.
Therefore, the cost of 18 roses = 53.10.
Now, to write an equation the relationship between the number of roses and the total cost of the roses:
Cost of per rose = 2.95.
As, given in question:
Number of roses =
Total cost of the roses =
Total cost of the roses = Cost of per rose × Number of roses.
So, the equation is:
Therefore, the equation is And the cost of 18 roses is 53.10.

Answer: 179
Step-by-step explanation:
The population variance cannot be determined solely from a sample, but the sample variance can provide an estimate of it based on the data collected from the sample.
The population variance ) represents the variance of the entire population. In this case, the population consists of 179 students. However, if we take a sample of 25 students from this population, the variance of this sample is called the sample variance
The sample variance ) is used to estimate the population variance ). It is calculated using the following formula:

Cassie has a small cube shaped box. Its volume is 64 cubic cm. What is the area of one face of tje box.
Answer: One face is 16 square centimeters.
Step-by-step explanation: To find the area of a face, you need to know the length of the side. All the sides of the cube are the same, so take the cube root of 64.
[tex]\sqrt[3]{64}=4[/tex] cm is the length of the side
The area of one face is the side length squared 4² = 16
4cm × 4cm = 16 square centimeters.
Answer:
surface area of one face of the cube will be 16 cm².
Step-by-step explanation:
Cassie has a small cube shaped box.
Volume of the box is 64 cm³
We have to find the area of one face of the box.
Let one side of the box is x
Then volume = x³ = 64
x³ = 4³
x = 4
Now area of one face of the cube = x²
then area = 4² = 16 cm²
Therefore, surface area of one face of the cube will be 16 cm².

Find the volume of a right circular cone that has a height of 13 in and a base with a
circumference of 5.1 in. Round your answer to the nearest tenth of a cubic inch.
Answer:
Step-by-step explanation:
the formula for finding the volume of a cone would be V= 3.14 r sqaured * h/3
so plug that in and it would be 3.14(5.1) sqaured * 13/3
3.14 is the formula of pie which is in the formula for finding the volume of
5.1*5.1= 26.01
3.14* 26.01= 81.67
13/3= 4.34
81.67* 4.34= 354.45
The volume of a right circular cone that has a height of 13 in and a base with a circumference of 5.1 inches is 8.97824.
Calculation of the volume of right circular cone:
Since
We know that
Volume = [tex]\pi r^2 \frac{h}{3}[/tex]
Since the circumference is 5.1 inches
So here the radius be like
Circumference = [tex]2\pi r[/tex]
5.1 = 2(3.14) r
r = 0.8121
Now the volume should be
[tex]= 3.14 \times (0.8121)^2 \frac{13}{3}[/tex]
= 8.97824
Hence, The volume of a right circular cone that has a height of 13 in and a base with a circumference of 5.1 inches is 8.97824.

Emily claims that a tree height of 43 inches is an outlier for the distribution. Based on the 1.5x IQR rule for outliers, is there evidence to support the claim?
Given:
Emily claims that a tree height of 43 inches is an outlier for the distribution.
To find:
Evidence to support the claim if any.
Solution:
The starting and the end of the box in box plot are first and third quartile respectively.
From the given box plot it is clear that, [tex]Q_1=34[/tex] and [tex]Q_3=38[/tex].
[tex]IQR=Q_3-Q_1[/tex]
[tex]IQR=38-34[/tex]
[tex]IQR=4[/tex]
According to 1.5x IQR rule for outliers, all the data values lies outside the interval [tex][Q_1-1.5\times IQR,Q_3+1.5\times IQR][/tex] are outliers.
Now,
[tex]Q_3+1.5\times IQR=38+1.5(4)[/tex]
[tex]Q_3+1.5\times IQR=38+6[/tex]
[tex]Q_3+1.5\times IQR=44[/tex]
We know that, 43<44.
Since, 43 is not greater than [tex]Q_3+1.5\times IQR[/tex], therefore, 43 is not an outlier and there is no evidence to support the claim.
Therefore, the correct option is D.

You take a package to the local shipping company. They charge $0.72 per pound, and also has a fixed cost of $5
per package. If P represents the number of pounds of your package, and C is the total cost of shipping your
package, which of these is the correct relationship between P and C?
Answer:
yoy didnt put a picture of the answer choices, so I'm not sure which one this would be, but the answer would be C=5 + .72P
Step-by-step explanation:
C is the total cost, so that would be on the opposite side of the equal sign from P. the 5 would be the constant, since that is the starting price for all packages, and the .72 is the price per pound, so you would have to multiply .72 by P pounds in order to complete the equation.
