Given that :
Area of a rectangle is : A = l×b
For smaller garden,
Length, l = [tex]\dfrac{1}{2}\ \text{foot}[/tex]
Width, [tex]b=\dfrac{2}{3}\ \text{foot}[/tex]
Area of a smaller garden is :
[tex]A=\dfrac{1}{2}\times \dfrac{2}{3}\\\\A=0.34\ \text{foot}^2[/tex]
For larger garden,
length, l' = 4 feet
Width, b' = 5 feet
Area of a larger garden is :
[tex]A'=l'\times b'\\\\A'=4\times 5\\\\A'=20\ \text{feet}^2[/tex]
So, the area of a smaller garden is 0.34 sq ft and that of a larger garden is 20 sq ft.
what is the median score on the exam ?
a) 70
b) 75
c) 77.5
d) 85
Answer:
b) 75
Step-by-step explanation:
The median (middle quartile) marks the mid-point of the data and is shown by the line that divides the box into two parts.
Therefore, from inspection of the box plot diagram, the median is 75
Additional information
Lower quartile (Q1) = 70
Median (Q2) = 75
Upper quartile (Q3) = 85
IQR = Q3 - Q1 = 85 - 70 = 15
Minimum value = 55
Maximum value = 100
Range = Max - Min = 100 - 55 = 45

HELPP! The perimeter of a rectangle is 104 inches. The width is 6 inches less than 3 times the length. Find the
width of the rectangle.Show each step and explain what was performed for each step.
Answer:
Length of the rectangle = 14.5 inches
Width of the rectangle = 37.5 inches
Step-by-step explanation:
Let the length of a rectangle = a inches
Since, width of the rectangle is 6 inches less than 3 times the length,
w = 3a - 6
Perimeter of the rectangle = 104 inches
Formula to calculate the perimeter of a rectangle = 2(length + width)
104 = 2[a + (3a - 6)]
2a + 2(3a - 6) = 104 → [Starting equation]
8a - 12 = 104 → [Distributive property]
8a - 12 + 12 = 104 + 12 → [Addition property of equality]
a = [tex]\frac{116}{8}=14.5[/tex] → [Division property of equality]
a). width of the rectangle = (3a - 6) = 37.5 inches
b). length of the rectangle = 14.5 inches
The width of the rectangle is 37.5 inches and the length of the rectangle is 14.5 inches.
The perimeter of a rectangle is represented as follows:
perimeter = 2l + 2w
where
w = width
l = length
Therefore,
perimeter = 104 inches
let
the length = a
Therefore,
width = 3a - 6
Therefore,
104 = 2a + 2(3a - 6)
104 = 2a + 6a - 12
116 = 8a
a = 116 / 8
a = 14.5 inches
width = 3(14.5 ) - 6 = 37.5 inches
Therefore, the width of the rectangle is 37.5 inches and the length of the rectangle is 14.5 inches.

solve for x
please it is due today if right ill give brain list
Answer:x=y-bm
Step-by-step explanation:
Answer:
x = y-b/m
Step-by-step explanation:
Step 1: y = mx + b
Step 2: Bring b to the left side of the equation
Step 3: y - b = mx
Step 4: To isolate for x, we must get rid of m. Therefore, divide m on both sides of the equation
Step 5: y-b/m = mx/m
Step 6: On the right side of the equation, m and m crosses out.
Step 7: All we have left is: y-b/m = x
(Or you can write it as x = y-b/m)

Answer:
I think it's 31
Step-by-step explanation:
Answer:
x = 31°
Step-by-step explanation:
The two triangles seem to be identical.
All angles of a triangle must add up to 180° to make a triangle.
So, 53° + 96° = 149°
Subtract 149° from 180°
180° - 149° = 31°
So x = 31°

Step-by-step explanation:

Belmont will produce 584,615 metric tons of CO₂ after 6 years, growing at the rate of 10% every year, currently emitting 330,000 metric tons of CO₂.
What do we mean by growth?The value of most things is not constant in this world. If we observe correctly, the value of some of the things rises, while others fall. If there is a rise, we call it growth.
Growth can be determined by the formula,
V = V₀(1+r)ⁿ, where V is the final value, V₀ is the initial value, r is the rate and n is the time.
How do we solve the given question?In the question, we are given that Belmont is a growing industrial town. Every year, the level of CO2 emissions from the town increases by 10%.
We are asked that if the town produced 330,000 metric tons of CO2 this year, how much will be produced 6 years in the future.
As we see that the amount of CO₂ emission is growing, to find the amount of CO₂ emitted in the 6th year, we use the growth formula,
V = V₀(1+r)ⁿ, where V is the final value, V₀ is initial value, r is rate, and n is the time period.
Here, V₀ = 330,000 metric tons, r = 10%, n = 6 years.
∴ V = 330,000(1 + 10%)⁶
or, V = 330,000(1.1)⁶ = 330,000*1.771561 = 548615.13
or, V = 548615 metric tons (rounded to nearest whole number).
∴ Belmont will produce 584,615 metric tons of CO₂ after 6 years, growing at the rate of 10% every year, currently emitting 330,000 metric tons of CO₂.

V= (12.9)(5.5)(4.7)
V= 333.465 cubic feet
The tank contains: 210 cubic feet of water
To find percentage: current amount / maximum capacity (this would be our volume) multiplied by 100% =

If DF=7x-3 and EG=5x+9, find the value of X
Answer:
[tex]x=6[/tex]
Step-by-step explanation:
Using the given measurements of the angles and the lengths of the sides, we can determine that this figure must be a rectangle.
Diagonals of a rectangle are always equivalent/congruent.
We can use this information to set up an equation:
[tex]DF=EG\\7x-3=5x+9[/tex]
Add 3 to both sides:
[tex]7x-3+3=5x+9+3\\7x=5x+12[/tex]
Subtract 5x from both sides:
[tex]7x-5x=5x-5x+12\\2x=12[/tex]
Divide both sides by 2
[tex]\frac{2x}{2}=\frac{12}{2}\\x=6[/tex]
Answer:
6[tex] \: [/tex]
Step-by-step explanation:
A rectangle is a parallelogram with equal angles and the diagonals of a rectangle are of equal length.

Therefore,

[tex]{ \longrightarrow \qquad{ \sf{ \pmb {7x - 3 = 5x + 9}}}} \: \: \\ \\[/tex]
Subtracting 5x from both sides we get :
[tex] \\ { \longrightarrow \qquad{ \sf{ \pmb {7x - 5x - 3 = 5x - 5x + 9}}}} \: \: \\ \\[/tex]
[tex]{ \longrightarrow \qquad{ \sf{ \pmb {2x - 3 = 9}}}} \: \: \\ \\[/tex]
Adding 3 to both sides we get :

[tex]{ \longrightarrow \qquad{ \sf{ \pmb {2x = 12}}}} \: \: \\ \\[/tex]

a. a sample mean near 80 with a=.05b. a sample mean much different than 80 with a=.05c. a sample mean much different than 80 with a=.01d. a sample mean near 80 with a=.01
Answer:
The answer is "Option c"
Step-by-step explanation:
In the given question, in choice c the numerice value is missing, that is "0.05".
The null hypothesis can only be rejected whether there is enough statistical data than that of the critical values.
The options A and B are not accurate, because the mean test of around 80 means that now the check-in and check number is lower, giving small statistics of the experiment and resulting in the null hypothesis is not rejected. In the C or D is true, however, the importance or alpha level need to be tested Alpha level 0.05 is 5% likely to reject an absolute zero hypothesis so, although 0.01 alpha level is 1% more likely to oppose an absolute zero hypothesis, Therefore, the alpha 0.05 rating is stronger.22

Playing cards numbered from 1 to 20 are mixed thoroughly and kept it in a box. One card is taken at random from the box. What is the probability of the selected/drawn playing cards?1. Is a Prime number.2. A factor of 20.3. A composite number.4. A multiple of 3.5. A perfect square.
Step-by-step explanation:
Probability is the ratio of the expected outcome (event) to the total outcome (sample space)
Probability = expected outcome/total outcome
If Playing cards numbered from 1 to 20 are mixed thoroughly and kept it in a box, the total number of sample space is 20
1) To calculate of getting a prima number.
Events = {2, 3, 5, 7,11,13,17,19}
n(events) = 8 elements
Pr(selecting a prime) = 8/20 = 2/5
2) If a factor of 20 is selected
Factor of 20 F = {2, 4, 5, 10, 20}
n(F) = 5
Pr(factor of 20) = 5/20 = 1/4
3) A composite number are 2 digits numbers.
Composite number C = {10,11,12,13,14,15,16,17,18,19,20}
n(C) = 11
Pr(a composite number) = 11/20
4) For multiple of 3.5
Multiple of 3.5 M = {3.5, 7.0, 10.5, 14.0, 17.5}
n(M) = 5
Pr(multiple of 3.5) = 5/20 = 1/4
5) For perfect squares
Perfect squares P = {1, 4, 9, 16}
n(P) = 4
Pr(perfect squares) = 4/20 = 1/5

Consider the figure. Determine the value of z.
Answer:
z=90
Step-by-step explanation:
Answer:
12x+11 = 47 (reason: vertical angles)
12x = 36
x = 3
12(3)+11 + w = 90 (reason: right angles)
36+ 11 + w = 90
47+w = 90
w = 43
43+z+47 = 180 (reason: linear pair)
90+z = 180
z = 90
