a) If side a measures 90 feet and side b measures 120 feet, how many feet of flowers will be planted along side c, the hypotenuse of the triangle? Show your work and explain your reasoning.
(image below)
Answer:
90 squared is 8,100, and 120 squared is 14,400. So to figure out what c is you do 90^2 + 120^2 = Square Root of 22,500 which is 150.
So c = 150
Step-by-step explanation:
So C=150
hope this helps :D
By using the Pythagorean theorem, we will see that side C measures 150ft.
How to get the length of side C?
We can see that side C is the hypotenuse of a right triangle. We know both catheti of said triangle, then we can use the Pythagorean theorem.
It says that the sum of the squares of the cathetus is equal to the square of the hypotenuse. Then we have:
A^2 + B^2 = C^2
We know that:
A = 90ft
B = 120ft
Replacing that we get:
√((90ft)^2 + (120ft)^2) = C = 150ft
Then we conclude that side C measures 150ft.

Simplify the expression. −5x + 8y + 2x − 3y
Final answer:
To simplify the expression −5x + 8y + 2x − 3y, combine like terms, resulting in −3x + 5y.
Explanation:
To simplify the expression −5x + 8y + 2x − 3y, you want to combine like terms. The like terms are those with the same variable raised to the same power. In this expression, −5x and 2x are like terms, as are 8y and −3y.
Combine −5x and 2x: (−5 + 2)x = −3x
Combine 8y and −3y: (8 − 3)y = 5y
After combining like terms, the simplified expression is −3x + 5y.
solve 21/8.1 = 105/m
Answer:
m = 40.5
Step-by-step explanation:
21/8.1 = 105/m
Croos multiplying the fractions, we get
21m = 850.5
m = 850.5/21
m = 40.5
hope it helps!
To solve the proportion 21/8.1 = 105/m, cross-multiply to get 21m = 850.5. Then, divide both sides by 21 to find m = 40.5.
Explanation:To solve the equation 21/8.1 = 105/m, you can use cross-multiplication. By setting up the proportions correctly, you ensure that meters, being the only unit involved, is properly handled in the calculations.
First, cross-multiply to get 21 * m = 105 * 8.1. This simplifies to 21m = 850.5. Next, divide both sides of the equation by 21 to isolate m on one side, leaving you with m = 850.5 / 21. Upon dividing, you get m = 40.5.
It's important to remember that when dealing with ratios or proportions, canceling equivalent terms in the numerator and denominator simplifies the problem, making it easier to solve. Moreover, understanding how to deal with powers of 10 is essential, such as knowing that for 105/103 = 105-3 = 102 is helpful in many mathematical problems.

Step-by-step explanation:
A political action committee is interested in finding out what proportion of voters will
support an environmental initiative. Obtain a sample size that will ensure a margin of
error of at most 0.09 for a 95% confidence interval. Similar initiatives in the past have
gotten 93% support.
Answer:
[tex]n=\frac{0.93(1-0.93)}{(\frac{0.09}{1.96})^2}=30.875[/tex]
And rounded up we have that n=31
Step-by-step explanation:
First we need to find the critical value for the margin of error desired. The confidence level is 0.95 so then the significance is [tex]\alpha=1-0.95=0.05[/tex] and the critical value for this case would be:
[tex] z_{\alpha/2} =\pm 1.96[/tex]
The margin of error for the proportion interval is given by this formula:
[tex] ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}[/tex] (a)
And on this case we have that [tex]ME =\pm 0.09[/tex] and we are interested in order to find the value of n, if we solve n from equation (a) we got:
[tex]n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}[/tex] (b)
The estimated proportion for this case is [tex]\hat p =0.93[/tex]. And replacing into equation (b) the values from part a we got:
[tex]n=\frac{0.93(1-0.93)}{(\frac{0.09}{1.96})^2}=30.875[/tex]
And rounded up we have that n=31
A new laptop computer costs $800. The sales tax on the computer is $48. What is the PERCENT of the sales tax?
Answer:
6% sales tax
Step-by-step explanation:
48 / 800 = x / 100
What did you do to turn 800 into 100? Divide by 8.
Since we divided the denominator by 8, we also divide the numerator by 8.
48 / 8 = 6
6% sales tax
Final answer:
The percent of the sales tax on an $800 laptop computer with a $48 sales tax is 6%. This is found by dividing the sales tax by the cost of the computer and then multiplying by 100.
Explanation:
To calculate the percent of the sales tax for the laptop computer, you need to follow these steps:
Convert the sales tax amount to a decimal by dividing the sales tax by the cost of the item before tax.
For example: $48 (sales tax) ÷ $800 (cost of the laptop) = 0.06.
Then, convert the decimal to a percentage by multiplying it by 100.
Continuing the example: 0.06 × 100 = 6%.
Therefore, the sales tax rate for the laptop computer is 6%.

Which of the following is a description of the data with a correlation coefficient of 1?
A) no correlation
B) perfect positive correlation
C) high positive correlation
D) perfect negative correlation
Answer:
perfect negative correlation
Step-by-step explanation:
correlation coefficient is the term used in statistic which provides the information of strength of relation between two variables. This value suggests if there is change in value of one variable, what will be the change in the variable and how much will value of that change.
What will be the change : it suggest whether change in value of one variable other will be increase or decrease .
If there is increase in one variable and other also increases it suggest there is positive correlation .
If there is decrease in one variable and other also decrease it suggest there is positive correlation .
how much will value of that change: It means to say if there is change in one variable by how much amount other variable will change.
If the value of correlation coefficient is high it means that change in value for one variable is high in to response change in other variable .
It values ranges from -1 to +1 high
while sign depicts type of relation that is positive or negative .
value from - 1 to + 1 depicts strength of the relation .
with - 1 depicting perfect negative correlation
+1 depicting perfect positive correlation.
In the problem it is given correlation coefficient is 1 which means it is positive and value of one means that if there x percentage increase in one variable then other variable will also increase by x percentage and vice versa.

The cross-section of a pipe has a width of 6 centimeters and a height of 15 centimeters.
Calculate the volume of the pipe.
Use 3.14 for pi. Round to the nearest tenth.
Answer:
Volume of the pipe = 423.9cm³
Step-by-step explanation:
Width = 6cm = diameter
Radius (r) = d / 2 = 6 / 2 = 3cm
Height = 15cm
Volume = ?
π = 3.14
Assuming the shape of the pipe is that of a cylinder, then we can easily find its volume just by calculating the volume of the cylinder.
Volume of a cylinder = πr²h
π = 3.14
r = radius of the cylinder
h = height of the cylinder
Volume = 3.14 × 3² × 15
Volume = 3.14 × 9 × 15
Volume = 423.9cm³
The volume of the pipe is 423.9cm³
The volume of the given pipe is [tex]424.12\ cm^3[/tex].
To calculate the volume of the pipe, assume the pipe is cylindrical and use the formula for the volume of a cylinder. The formula is given by:
[tex]V = Area\ of\ cross\ section \times height[/tex]
Since the pipe is cylindrical, the cross section is a circle. Therefore:
[tex]Area\ of\ cross\ section = \pi r^2[/tex]
where r = radius of cross section
Given width = 6 cm = diameter of the cross section = 2r
[tex]2r = 6\ cm \implies r = \frac{6}{2}\ cm = 3\ cm[/tex]
Therefore:
[tex]Area\ of\ cross\ section=A = \pi r^2 = \pi (3)^2 = 9\pi\ cm^2[/tex]
Assuming the 'height' mentioned is the length through which fluid is flowing, and given the cross-sectional area, the volume formula simplifies to:
[tex]V = A\times h[/tex]
Given height (length of cylinder) = 15 cm:
[tex]V = 9\pi \times 15\ cm^3 = 135\pi \ cm^3 \approx 424.12\ cm^3[/tex]
So, the volume of the pipe, assuming it as cylindrical, is [tex]424.12\ cm^3[/tex].

A water tank holds 621 gallons but is leaking at a rate of 4 gallons per week. A second water tank holds 828 gallons but is leaking at a rate of 7 gallons per week. After how many weeks will the amount of water in the two tanks be the same?
Answer:
69 weeks
Step-by-step explanation:
Let the number of weeks be x.
The first tank holds 621 gallons is leaking at a rate of 4 gallons per week. This means that after x weeks, the amount of water in the tank is:
621 - 4x
The second tank holds 828 gallons is leaking at a rate of 7 gallons per week. This means that after x weeks, the amount of water in the tank is:
828 - 7x
After a certain amount of weeks, the amount of water in both tanks is the same. That means that:
621 - 4x = 828 - 7x
=> 7x - 4x = 828 - 621
3x = 207
x = 207 / 3 = 69
This means that the amount of water in the tank will be the same after 69 weeks.
