Joseph wants to plant gloxinia and hydrangeas in two similar rectangular gardens. The length of one garden is 5 ft, and the width is 4 ft. The other garden's length is 20 ft. What is the width of the second garden?
Answers
Answer:
width = 1 ft
Step-by-step explanation:
"Similar" means same area.
Therefore area of first garden = area of second garden.
Let x be the width of the second garden.
5x4 = 20x
x = 1 ft
The area of the rectangle A is 54 m² and the area of rectangle B is 24 m². If the rectangles are similar and the length of the rectangle A is 9 meters, find the length and width of both rectangle's.

Thaddeus shakes his head as he pays $12.37 to the clerk for lunch. Complaining to a friend, Thaddeus says, “Do you realize that is 0.2% of my monthly income?” His friend replies, “I think you made a mistake. That should be 2%. You messed up on the decimal point.” (a) Assuming Thaddeus is not wrong, what is his monthly income? (b) If Thaddeus’ friend is correct, what is Thaddeus’ monthly income?
Answers
Answer:
a) If Thaddeus is not wrong, his monthly income is $6,185.
x/12.37 = 100/0.2
0.2x = 1237
x = 1237/0.2x
x = 6,185
b) If Thaddeus's friend is correct, Thaddeus's monthly income is $618.5
x/12.37 = 100/2
2x = 1237
x = 1237/2x
x = 618.5
If Thaddeus is not wrong, his monthly income is $6,185.
If Thaddeus's friend is correct, Thaddeus's monthly income is $618.5.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Thaddeus shakes his head as he pays $12.37 to the clerk for lunch.
a) If Thaddeus is not wrong then let his income be x.
So, x/12.37 = 100/0.2
0.2x = 1237
x = 1237/0.2x
x = 6,185
b) If Thaddeus's friend is correct
x/12.37 = 100/2
2x = 1237
x = 1237/2x
x = 618.5

1/5=2/10=5/25
To get 2/10, since, in the denominators, to go from 5 to 10, you multiply 5 by 2, I multiplied 1 and 2 to get the answer.
For 5/25, to go from 1 to 5 you multiply 1 by 5, so you multiply 5 by 5, and that's 25, so the denominator for that fraction is 25.

A local weather enthusiast wants to see if the last five summers have been warmer than normal for Eloy, Arizona. From the National Oceanic and Atmospheric Administration (NOAA), he knows the 30-year average for July was 90° with a standard deviation of 2. 1°. The last five summers recorded have an average of 93. 5°. If he uses a = 5%, which of the following would be valid based on the data he has gathered? He can conclude that the summers have been warmer than the 30-year average. He can conclude that the summers will continue to be warmer for the next 10 years. He does not have enough information to make a decision. The average for the last five years fits with the 30-year average.
Answers
For local weather of Eloy, Arizona, the average for the last five years fits with the 30-year average.
What is the standard deviation data?The standard deviation of the data is the half of the difference of the highest value and mean of the data set.
The 30-year average for July was 90°. The standard deviation for this average is 2.1°. Thus, the temperature is lie between the [tex]\pm 2.1[/tex] ranges around the 90° in the month of July.
Therefore, the range of the temperature is,
[tex]t=90-2.1=87.9^o\\t=90+2.1=92.1^o[/tex]
The last five summers recorded have an average of 93. 5° and the value of a is 5%. Thus, the reduction is,
[tex]t=92-92\times\dfrac{2.5}{100}\\t=89.70^o[/tex]
This value of temperature lies between the range of 87.9-92.1 degrees Celsius. Hence, the two average are probably the same.
Hence, for local weather of Eloy, Arizona, the average for the last five years fits with the 30-year average. Option D is correct.

A. 10

D. 99
Answers
The actual degree measure of arc KJ is 99 degrees
Circle geometryFrom the given informtion
arc KL = 12x+4
arc KJ = 8x-6
<E = 99 degrees
The equation required to get the value of "x" is given as:
12x + 4 + 8x - 6 + 99 = 360
20x + 97 = 360
20x = 360 - 97
20x = 263
x = 13.15
For the arcKL
arcKJ = 8(13.15) - 6
arcKJ = 99degrees

The volume of a cone is 540pi
Work out the height,of the cone.
The radius is 9cm
Answers
Formula for volume of a cone = pi x r^2 x h/3
540pi = pi x 9^2 x h/3
Divide both sides by pi:
540= 9^2 x h/3
Simplify:
540 = 81 x h/3
Divide both sides by 81:
6 2/3 = h/3
Multiply both sides by 3
H = 20
the height is 20 cm
