what is the length, in feet, of the side of the garden that is against the wall?
Answers
Answer:
The length, in feet, of the side of the garden that is against the wall is(60 - x - CD) ft.
Step-by-step explanation:
Consider the diagram below.
The wall is labelled as AD, the side perpendicular to the wall is labelled as AB and the side against the wall is labelled as CB.
It is provided that the rectangular garden is enclosed by 60 feet of fencing on three sides.
That is,
AB + CB + CD = 60 ft.
⇒ x + CB + CD = 60 ft.
Then the length, in feet, of the side of the garden that is against the wall is:
x + CB + CD = 60 ft.
⇒ CB = (60 - x - CD) ft.
Answer: 60-2x

find the percentage increase from 150 to 210
Answers
Answer:
40%
Step-by-step explanation:
First you have to determine the increase as a number:
increase = new number - original number
That means you have an increase of 210 - 150 = 60
Then you will need to divide the increase by the original number and multiply the answer by 100:
% increase = increase ÷ original number × 100
That will give you: 60 ÷ 150 × 100 = 40
Josie ate 5/8 of a pie and Marge ate 6/10 of a pie. Who ate more and therefore burped louder?
Answers
5/8 > 6/10
Hope this helps
Josie ate more and burped louder because 5/8 is greater than 6/10 and Josie ate 5/8 of the pie.
Given,
Josie ate 5/8 of a pie and Marge ate 6/10 of a pie.
We need to find who ate more and therefore burped louder.
We need to compare the given fraction and see which is greater.
We have,
Josie = 5/8 of a pie.
Marge = 6/10 of a pie.
Now,
We can compare the fraction in three ways:
Case 1. - In terms of %
5/8 x 100 = 62.5 %
6/10 x 100 = 60%
62.5 % > 60%
5/8 > 6/10
Case 2. - In terms of decimals
5/8 = 0.625
6/10 = 0.6
0.625 > 0.6
5/8 > 6/10
Case 3. -In terms of multiplying
5/8 = 6/10
5 x 10 = 6 x 8
50 = 48
50 > 48
5/8 > 6/10
5/8 is greater than 6/10 so the one who eats 5/8 of the pie ate more and burped louder.
Thus Josie ate more and burped louder.

Step-by-step explanation:
To do this you would just plug in the values into the variables so you get [tex]|-5^{2} +3^{2} |[/tex] and when you simplify you get |25+9| which when you add together you get |34| and the absolute value is just 34 since it is not negative.
If m = -5 and n = 3, then the value of the expression |m² + n²| will be 34.
What is Algebra?Algebra is the study of graphic formulas, while logic is the interpretation among those signs.
The expression is given below.
⇒ |m² + n²|
Put m = -5 and n = 3, then the value of the expression will be

The town of Tola has a population of 45,000 and produces 6 tons of garbage each week. Express this information in terms of the function f
Answers
Complete question:
The amount of garbage, G produced by a city with population p is given by G = f(p). G is measured in tons per week, and p is measured in thousands of people. The town of Tola has a population of 45,000 and produces 6 tons of garbage each week. Express this information in terms of the function f
Answer:
The information of town Tola can be represented in function as 6 = f(45)
Step-by-step explanation:
Given;
population of Tola, p = 45,000
amount of garbage produced in tons per week, G = 6 tons = 6,000 kg
The function is given by;
G = f(p)
where;
G is the amount of garbage produced in tons per week
p is the population of Tola
Substitute in the given values into the function
6000 = f(45,000)
6 = f(45)
Therefore, the information of town Tola can be represented in function as 6 = f(45)

Answers
Complete question is;
Use a t-test to test the claim about the population mean μ at the given level of significance α using the given sample statistics. Assume the population is normally distributed.
Claim: μ ≥ 8300,α= 0.10
Sample statistics: ¯x = 8000, s = 440, n = 24
a. What are the null and alternative hypotheses?
b. What is the value of the standardized test statistic? (Round to 2 decimal places as needed.)
c. What is the p-value? (Round to three decimal places as needed.)
d. Decide whether to reject or fail to reject the null hypothesis.
Answer:
A) Null hypothesis:H0: μ ≥ 8300
Alternative Hypothesis:Ha:μ < 8300
B) t = -3.34
C) p-value = 0.001
D) we will reject the null hypothesis
Step-by-step explanation:
A) We are told that the claim is: μ ≥ 8300. Thus, the null hypothesis would be the claim. So;
Null hypothesis:H0: μ ≥ 8300
Also, alternative hypothesis would be;
Alternative Hypothesis:Ha:μ < 8300
B)Formula for standardized test statistic with a t-test is;
t = (¯x - μ)/√(s/n)
Plugging in the relevant values, we have;
t = (8000 - 8300)/√(440/24)
t = -3.34
C) From online p-value from t-score calculator attached using t = -3.34, n = 24, significance level = 0.01, DF = 24 - 1 = 23 and a one - tailed test, we have;
p-value = 0.001421 ≈ 0.001
D) The p-value of 0.001 is less than the significance value of 0.01,thus we will reject the null hypothesis
What would the scatter plot show for data that produce a Pearson correlation of r = +0.88?

b. Points clustered close to a line that slopes down to the right
c. Points widely scattered around a line that slopes up to the right
d. Points widely scattered around a line that slopes down to the right
Answers
Answer:
The correct option is (a).
Step-by-step explanation:
The Pearson's correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.
Positive correlation is an association amid two variables in which both variables change in the same direction. A positive correlation occurs when one variable declines as the other variable declines, or one variable escalates while the other escalates.
Negative correlation is a relationship amid two variables in which one variable rises as the other falls, and vice versa.
In this case, it is provided that the Pearson correlation coefficient is, r = +0.88.
A correlation coefficient between ±0.70 to ±1.00 are considered as strong positive correlation.
The scatter plot for correlation coefficient between +0.70 to +1.00 shows:
A straight and upward moving trend of the pointA straight line can be formed using these points that slopes up to the rightPoints clustered close to this line that slopes up to the rightThus, the correct option is (a).

Suppose a company has a design maximum output of 280. Its actual output is 195 and its efficiency is 80%. Calculate its efficient output and its capacity utilization.
Answers
Answer:
Effective output = 224
Capacity Utilization = 80%
Step-by-step explanation:
Given the maximum output = 280
The actual output = 195
The efficiency = 80%
Below is the formula to calculate the efficiency.
Efficiency in percentage = (Effective output / Maximum output) x 100
Insert the given values in the formula.
80 =( Effective output / 280 ) x 100
Effective output = 280 x 0.8
Effective output = 224
Now the Capacity utilization ( %) = Actual output / Maximum output x 100
Capacity utilization in percentage = 224 / 280 x 100
Capacity Utilization = 80%

if point B is the midpoint of points A and C, find the value of x and AC. AB= 5x - 2, BC= 9x -10
Answers
Answer:
AC = 6 ÷ 7
x = 2
Step-by-step explanation:
Given that
AB = 5x - 2
BC = 9x - 10
So,
AC = AB + BC
= 5x - 2 + 9x - 10
14x -12 = 0
AC = 6 ÷ 7
As B is the mid point of point A and point C, so the value of x is determined by solving the given equations mentioned in the question
5x - 2 = 9x - 10
5x - 9x = -10 +2
-4x = -8
x = 2
Hence, the value of AC and the X is 6 ÷ 7 and 2 respectively
