Mr. Conner is placing stone tiles to make a patio. Each tile is 1 square foot. The drawing shows the dimensions of his patio. A quadrilateral is broken into a triangle and rectangle. The triangle has a base of 20 feet and a height of 6 feet. The rectangle has a base of 20 feet and a height of 12 feet. How many total stone tiles will Mr. Connor need for the patio?
Answer:
300 tiles
Step-by-step explanation:
From the above question, we know that the patio is a combination of a triangle and a rectangle.
Step 1
Find the area of the shape
a) Area of the Triangle = 1/2 × Base × Height
Base = 20 feet
Height = 6 feet
Area = 1/2 × 20 × 6
Area = 60 square feet
b) Area of the rectangle
= Length × Breadth.
The rectangle has a
Base = Breadth = 20 feet
Height = Length = 12 feet
Area = 20 × 12 = 240 square feet.
Total Area of the patio
= Area of Triangle + Area of square
= 60 square feet + 240 square feet
= 300 square feet
Step 2
We are told that each stone tile = 1 square foot.
Hence, if the total area of the patio = 300 square feet, the number of stone tiles that would be used is
1 square foot = 1 stone tile
300 square feet = 300 stone tiles.
Therefore,the total stone tiles that Mr. Connor will need for the patio is 300 stone tiles.

PLEASE HELP!!!!!Using the following image, solve for the trigonometry ratios of ∠D and ∠F.
Answer:
Here we have a triangle rectangle, where the length of one of the cathetus is: 15 (the one at the top)
And the length of the other cathetus is 8 units (i think, i can not see well the image)
Now, if we want to find the angle D.
In this case, the adjacent cathetus is the one of 15 units, and the opposite cathetus is the one of 8 units.
Then we can use the relation:
Tg(A) = (opposite cathetus)/(adjacent cathetus)
So:
Tg(D) = 8/15
D = ATg(8/15) = 28.1°
Now, for the angle F, the adjacent cathetus is the one of 8 units, and the opposite cathetus is the one of 15 units:
F = ATg(15/8) = 61.9°
Answer:
x= 17
Next, find the trigonometry ratios of ∠D.
sin∠D= 8/17
cos∠D= 15/17
tan∠D= 8/15
Finally, find the trigonometry ratios of ∠F.
sin∠F=15/17
cos∠F= 8/17
tan∠F=15/8
what is the frequency distribution table
Step-by-step explanation:
The frequency distribution table is a table that shows the particular values and corresponding frequencies. It consists of two tables first for clas interval and other for frequency.There are many types of frequency distribution such as Grouped frequency distribution, Cumulative frequency distribution., Relative cumulative frequency distribution etc.One way of organizing data is by constructing a frequency distribution table. A tally mark is used to record how often a particular score or number occurs. The number of times a score or number appears is called the frequency.
To construct a frequency distribution table:
a. list the scores or numbers from highest to lowest (or lowest to highest),
b. use tally marks to record how often each score or number appears, and
c. count the marks and record it in the frequency column.
What is the average length of a side in the shape made from the file datatest1.txt whose contents are shown below (just give to two decimal places)? -3,3 -4,-3 4,-2 6,5
Answer:
0.75
Step-by-step explanation:
The average length is given as the sum of all the lengths given divided by the number of lengths (frequency).
Mathematically:
Average = (Sum of lengths) / frequency
The lengths given are -3, 3, -4, -3, 4, -2, 6, 5. There are 8 lengths there.
The average is therefore:
Average = (-3 + 3 + (-4) + (-3) + 4 + (-2) + 6 + 5) / 8
Average = 0.75
The weight of an object on the moon is
5 of its weight on Earth. If a moon rock

the moon rock weigh on the moon?
Give your answer as a simplified mixed number.
Enter the number that belongs in the green box.
Answer:
40 2/5Ibs or [tex]40\frac{2}{5}[/tex] lbs
Step-by-step explanation:
Let weight of object on the moon be represented = Wm
weight of object on the Earth = We
In the above question, we are told:
The weight of an object on the moon is
5 of its weight on Earth.
Hence, mathematically, this is represented as:
5Wm = We
If a moon rock weighs 202 lbs on Earth
5Wm = 202lbs
Wm = 202lbs/5
Wm = [tex]40\frac{2}{5}[/tex]Ibs
Therefore, the moon rock weighs [tex]40\frac{2}{5}[/tex]Ibs on the moon.
Three years after a company was founded, its assets were $11,283,500. Ten years after being founded, its assets had grown to $21,794,600. During that period of time, at what rate did the company's assets grow per year?
Answer:
$1,051,110Step-by-step explanation:
Given
Step one:
Company's initial asset value = $11,283,500
Company's final asset value = $21,794,600
Step two
we can calculate the company's asset appreciation after 10 years as
$21,794,600- $11,283,500= $10,511,100
Step three
Hence, the growth rate of the company's asset value per year can be expressed as = $10,511,100/10= $1,051,110
2) Jeremy needs to build a fence around his pool. The pool and the sidewalk around it have
a distance around 300 feet, so the perimeter of the fence needs to be at least 300 feet. The
length of the fence is four more than two times the width. What is the length and width?
Answer:
length = 26.6
width = 11.3
Step-by-step explanation:
1. Set up the equation
(2x + 4)(x) = 300
2. Simplify
2x² + 4x = 300
3. Solve by completing the square
Divide by 2 to make "a" equal to 1
x² + 2x = 150
Find term to complete the square by squaring half of "b"
(2/2)² = 1
x² + 2x + 1 = 150 + 1
Factor perfect square trinomial
√x² + 2x + √1 = 151
(x+1)² = 151
Square root each side
x + 1 = ±12.3
Set up two possibilities and solve
x + 1 = 12.3
x = 11.3
x + 1 = -12.3
x = -13.3
The measurement cannot be negative so width is equal to 11.3
4. Use the width to solve for the length
11.3(2) + 4 = 26.6
The length and width is 26.6 and 11.3.
Calculation of the length and width:Since The length of the fence is four more than two times the width.
So here the equation should be
(2x + 4)(x) = 300
[tex]2x^2 + 4x = 300[/tex]
Now
Here we divided by 2
So,
[tex]x^2 + 2x = 150[/tex]
Now we determine the term
[tex](2/2)^2 = 1\\\\x^2 + 2x + 1 = 150 + 1[/tex]
Now applied the Factor perfect square trinomial
[tex]\sqrt x^2 + 2x + \sqrt1 = 151\\\(x+1)^2 = 151[/tex]
Now do the Square root each side
x + 1 = ±12.3
Here we required to set up two possibilities and solve
x + 1 = 12.3
x = 11.3
And,
x + 1 = -12.3
x = -13.3
The measurement should not be negative so the width is equal to 11.3
Now the width is
= 11.3(2) + 4
= 26.6
Therefore, The length and width is 26.6 and 11.3.

Below is the graph of f(x)=2ln(x). How would you describe the graph of g(x)=4ln(x)?
Reasoning:
g(x) = 4*ln(x)
g(x) = 2*2ln(x)
g(x) = 2*f(x)
Whatever the output f(x) is, it is doubled to get g(x). Recall that y = f(x), so we're really doubling the y values to visually stretch it vertically by a factor of 2. In short, g(x) is twice as tall compared to f(x).

PLEASE HELP The equation of the line below is: y = -4x + 4. y = -2x + 4. y = 2x + 4. None of these choices are correct.
Answer:
y = 2x+4
Step-by-step explanation:
The y intercept ( where it crosses the y axis ) is 4
The slope is positive because the line goes up from the bottom left to top right
We pick two point ( -2,0) and ( 0,4)
The slope is found by
m= (y2-y1)/(x2-x1)
= ( 4-0)/(0- -2)
= 4/ (0+2)
= 4/2
= 2
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = 2x+4
Answer:
The equation to this line is y=-4x+4
Step-by-step explanation:
If you look at the graph you can see that the y intercept is 4.
To find the slope take two points on the graph and plug it into be y2-y1/x2-x1
I chose (0,-2) and (-1,2) So 2+2=4 and -1-0= -1 so 4/-1= -4
Another one omg this is annoying
Answer:
Correct option: first one
Step-by-step explanation:
The equation f(x) = 5x + 1 is a function, because each value of x gives only one value of y.
Now let's find the inverse by switching f(x) by x and x by f'(x), then isolating f'(x):
[tex]x = 5f'(x) + 1[/tex]
[tex]5f'(x) = x - 1[/tex]
[tex]f'(x) = \frac{x - 1}{5}[/tex]
The inverse f'(x) is also a function, because each value of x gives only one value of x.
So we have that both the equation and its inverse are function, therefore the correct answer is the first option.
At what meter mark will Ario be when Miguel starts the race? Round to the nearest tenth. x = (StartFraction m Over m + n EndFraction) (x 2 minus x 1) + x 1 A number line goes from 0 to 25. A line is drawn from 3 to 25. The point at 3 is labeled Start and the point at 25 is labeled End. Miguel and his brother Ario are both standing 3 meters from one side of a 25-meter pool when they decide to race. Miguel offers Ario a head start. Miguel says he will start when the ratio of Ario’s completed meters to Ario’s remaining meters is 1:4.
Answer: 7.4 meters
Step-by-step explanation:
Start Mark = 3m
End mark = 25m
Total length to race = 25 - 3 = 22m
Position of both Ario and miguel = 3 meter from one side of the pool; that is 3 meters behind the START MARK
Ario's completed to remain ratio = 1:4
Total ratio = 5
Ario's Completed meters = (22/5) * 1 = 4.4m
Therefore, when Miguel starts the race, Ario will be on (4.4meters + number of meters behind the start mark)
= 4.4 meters + 3 meters = 7.4meters
The distance of Ario from the start point when miguel starts is;
7.44 m
We are told that A line is drawn from 3 to 25.This means distance of line = 25 - 3 = 22 m
The start point is at the 3 m mark.Miguel and his brother Ario are standing 3 m from one side of the pool.
This means that they are both 3 meters behind the start point.
We are told that the ratio of Ario’s completed meters to Ario’s remaining meters is 1:4.Thus, ario's completed meters when Miguel will start is;
¹/₅ × 22 = 4.4 m
Since Miguel is 3 m from the start and Ario has just done 4.4 m, then it means that;Distance of miguel from Ario when miguel starts = 3 + 4.4 = 7.4 m

Subtract 3/4 from both sides.
[tex]\sf \frac{1}{2} x=\frac{1}{20}[/tex]
Multiply both sides by 2.

Step-by-step explanation:
2^{2*3/4} × 2^{x}=2^{4×2/5}
2^{3/2} × 2^{x}= 2^{8/5}
2^{3/2+x}=2^{8/5}
equate powers
{3+2x}/2= 2^2
5{3+2x}= 2{8}

Find the value of X and Y in the following parallelogram.AD =X+8 D=2y +13 C=16-x CB=5y+4 AB=o
Answer:
The answer is below
Step-by-step explanation:
AD = X + 8 ∠D = 2y +13 ∠C = 16 - x CB = 5y+4
In a parallelogram, consecutive angles are supplementary and opposite sides are equal.
Therefore for parallelogram ABCD, AB = CD, CB = AD
Since AD = CB (opposite sides of a parallelogram are equal):
x + 8 = 5y + 4
5y - x = 8 - 4
5y - x = 4 (1)
∠C + ∠D= 180° (consecutive angles of a parallelogram are supplementary). Therefore:
16 - x + 2y + 13 = 180
2y - x + 29 = 180
2y - x = 180 -29
2y - x = 151 (2)
To find x and y, subtract equation 1 from equation 2:
3y = -147
y = -49
Put y = -49 in equation 2
2(-49) - x = 151
x = -98 - 151
x = -249

current interest rate is 7.2%/a compounded monthly. The term of Lauren's loan is 20
years. How much will Lauren pay per month?
Answer:
$1,313.3 per month
Step-by-step explanation:
A=p(1+r/n)^nt
P=principal=$75,000
r=interest rate=7.2%=0.072
t=20 years
n=12 months
A=p(1+r/n)^nt
=75,000(1+0.072/12)^12*20
=75,000(1+0.006)^240
=75,000(1.006)^240
=75,000(4.2026)
=315,195
A=$315,195
The term of Lauren's loan=20 years
20 years×12 months=240 months
Lauren's pay per month =$315,195/240
=$1,313.3125
Approximately $1,313.3 per month
BRAINLIEST! ASAP! A boat travelling at top speed upstream moves at 15km/hr. When it travels downstream, again at top speed< it moves at 25km/hr. What is the boat's top speed in still water?
Answer:
20 km/hr
Step-by-step explanation:
The boat's still-water speed is the average of its speeds against and with the current:
(15 +25)/2 = 20 . . . km/hr
__
If you want to write equations, you can let b and c represent the speeds of the boat and current in km/hr.
b - c = 15 . . . . upstream speed
b + c = 25 . . . . downstream speed
Add these two equations, and you get ...
(b -c) +(b +c) = (15) +(25)
2b = 40
b = 20 . . . . divide by 2
The speed of the boat in still water is 20 km/hr.
Answer:
20 km/hr
Step-by-step explanation:
To solve this, you have to find the average speed it is going. To find this, you just add up all of the speeds mentioned and divide it by the number of speeds you added.
15 +25=40
40/2=20
20km/hr!!!

Answer:
115
Step-by-step explanation:
It adds 3 every time and starts with -38. Our equation is:
a52 = -38+3(52-1);
a52 = -38 + 153
a52 = 115
Answer:
115
Step-by-step explanation:
→ First we need to work out the nth term. First we find the difference between each term
-38, -35, -32, -29... ⇔ +3
→ We know the first bit is 3n now we have to find the other section. We need to write the 3 times tables on top of each corresponding term
3 , 6 , 9 , 12
-38, -35, -32, -29...
→ We can see the to get from 3 to -38 we minus 41. So the nth term is
3n - 41
→ Now we substitute in 52 for n
3 × 52 - 41
→ Simplify

quarters to Lisa, but she still has $1
more. How many quarters does Lisa
have in the beginning?
E. 5
F. 10
G. 15
H. 20
Answer:
5
Step-by-step explanation:
If Lisa has x quarters and Brenda has 3x quarters, we can write:
80% * 3x = 4 + (20% * 3x + x) -- We write 4 because 1 dollar = 4 quarters
0.8 * 3x = 4 + (0.2 * 3x + x)
2.4x = 4 + 1.6x
0.8x = 4

How do you factor this expression: x^3 + 9x^2 + 27x + 27. Thanks! :)
Answer:
(x + 3)³
Step-by-step explanation:
Use rational root test to check for possible rational roots.
Factors of 27 are 1, 3, 9, and 27.
Factors of 1 are 1.
Possible rational roots are:
±1/1, ±3/1, ±9/1, ±27/1
Checking each one, we find that -3 is a root. So x + 3 is a factor.
Knowing that, we can use grouping to factor.
x³ + 9x² + 27x + 27
x³ + 9x² + 18x + 9x + 27
x (x² + 9x + 18) + 9 (x + 3)
x (x + 6) (x + 3) + 9 (x + 3)
(x + 3) (x (x + 6) + 9)
(x + 3) (x² + 6x + 9)
(x + 3) (x + 3)²

a. Feelings about weight is the response (dependent) variable. Sex is the explanatory (independent) variable. The feelings about weight depend on the sex
b. Summary of observed counts
Women Men Total
Overweight 38 18 56
Right weight 99 35 134
Underweight 6 25 31
Number 143 78 221
c. Percentage of the 143 women responding in each category:
1. Overweight = 38/143 = 26.6%
2. Right weight = 99/143 = 69.2%
3. Underweight = 6/143 = 4.2%
d. Percentage of the 78 men responding in each category:
1. Overweight = 18/78 = 23.1%
2. Right weight = 35/78 = 44.9%
3. Underweight = 25/78 = 32%
e. Summary of feelings about weight:
Women Men
Overweight 26.6% 23.1%
Right weight 69.2% 44.9%
Underweight 4.2% 32%
Step-by-step explanation:
a) Data:
Sample size = 221
Women Men Total
Overweight 38 18 56
Right weight 99 35 134
Underweight 6 25 31
Number 143 78 221
b) To obtain the percentage of feelings about weight for each category, the number of those who feel overweight, right weight, or underweight is divided by the total number of women or men. The value obtained, which is in decimal form, is then converted to percentage by multiplying with 100.
