A new Community Sport complex is being built in safe harbor the perimeter of the rectangular playing field is 402 yards the length of the field is 9 yards less than quadruple the width what are the dimensions of the playing field?
Answer:
length = 159 yardswidth = 42 yardsStep-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
Perimeter = 402 yards
The statement
the length of the field is 9 yards less than quadruple the width is written as
l = 4w - 9
Substitute this is expression into the above formula and solve for the width
That's
402 = 2( 4w - 9) + 2w
402 = 8w - 18 + 2w
10w = 402 + 18
10w = 420
Divide both sides by 10
w = 42Substitute this value into l = 4w - 9
That's
l = 4(42) - 9
l = 168 - 9
l = 159Therefore
length = 159 yards
width = 42 yards
Hope this helps you

5. Which equation in point-slope form contains the point (4, –1) and has slope 3?
Answer:
y+1 = 3(x-4)
Step-by-step explanation:
Point slope form is
y-y1 = m(x-x1) where m is the slope and (x1 , y1) is a point on the line
y - -1 = 3(x-4)
y+1 = 3(x-4)
a tricycle travels 180km in 4 hours. What it's speed in km/hr
Answer:
45 km per hour
Step-by-step explanation:
We want to find the tricycle's speed in kilometers per hour.
Therefore, we must divide the kilometers traveled by the number of hours.
speed= kilometers / hours
The tricycle travels 180 kilometers in 4 hours.
speed= 180 km / 4 hrs
Divide 180 km by 4 hrs.
⇒ 180/4=45
speed= 45 km / hour
The tricycle's speed is 45 kilometers per hour.
Why the correct answer of this question is 7 while I always find 3 as the minimum value instead of 7? The picture includes two different solutions.
Answer:
see below
Step-by-step explanation:
This solution is based off of the Triangle Inequality, which states that the sum of the two shortest sides of a triangle must be greater than the longest side of the triangle. The solution looks at the diagram on the bottom where y = DB. Looking at ΔABD, to find the range of values for y, we must consider two possible cases: y is either the shortest side or the longest side. If y is the shortest side then y + 5 > 6 which means y > 1 and if y is the longest side then 6 + 5 > y which means 11 > y. Therefore, the range of values for y is 1 < y < 11.
Next, they made y as small as possible, which would be 1.1 in this case. Looking at ΔDCB, again, to find the range of values for x, we must consider two possible cases: x is either one of the shortest sides or x is the longest side. If x is one of the shorter sides then 1.1 + x > 8 so x > 6.9 and if x is the longest side, 1.1 + 8 > x so 9.1 > x. Therefore, the range of values for x is 6.9 < x < 9.1. The smallest integer value that satisfies this inequality is x = 7.

Answer:
[tex]\Huge \boxed{{x=15\°}}[/tex]
Step-by-step explanation:
Angles on a straight line add up to 180 degrees.
We can create an equation.
x + 165 = 180
Solve for x.
Subtract 165 from both sides.
x + 165 - 165 = 180 - 165
Simplify the equation.
x = 15
Answer:
15°
Step-by-step explanation:
Angle of a line with a center is 180°
To find x:
x = 180 - 165°
x = 15°
15° is the answer.

Step-by-step explanation:
A student has money in three accounts that pay 5%, 7%, and 8%, in annual simple (i.e. compounded once per year) interest. She has three times as much invested at 8% as she does at 5%. If the total amount she has invested is $1600 and her interest for the year comes to $115, how much money does she have in each account
Answer:
Amount invested in account with 5% annual interest = $300
Amount invested in account with 7% annual interest = $400
Amount invested in account with 8% annual interest = $900
Step-by-step explanation:
Let the money invested in account with 5% annual interest = [tex]x[/tex]
As per question statement,
Money invested in account with 8% annual interest = [tex]3x[/tex]
Given that total amount invested in three accounts = $1600
So, Money invested in account with 7% annual interest = 1600- [tex]3x[/tex] -[tex]x[/tex] = 1600- [tex]4x[/tex]
For one year, the compound interest is same as that of Simple Interest.
Formula for simple interest is given as:
[tex]SI =\dfrac{PRT}{100}[/tex]
Where, P is the amount invested
R is the annual rate of interest
T is the time for which the amount is invested.
As per question statement:
[tex]\dfrac{x\times 5\times 1}{100}+\dfrac{(1600-4x)\times 7\times 1}{100}+\dfrac{3x\times 8\times 1}{100} =115\\\Rightarrow 5x\times +1600\times 7-28x+24x=11500\\\Rightarrow 29x-28x = 11500-11200\\\Rightarrow \bold{x =\$300}[/tex]
Amount invested in account with 5% annual interest = $300
Amount invested in account with 7% annual interest = $1600-$1200 = $400
Amount invested in account with 8% annual interest = $900

====================================================
Explanation:
There are two methods to approach this type of problem.
-------------------------------------
Method 1
A = junior
B = girl
P(A) = probability of selecting a junior
P(B) = probability of selecting a girl
P(B) = (number of girls)/(number total)
P(B) = (4+7+3+4)/(4+4+5+7+2+3+1+4)
P(B) = 18/30
P(B) = 9/15
P(A and B) = probability of selecting a girl who is a junior
P(A and B) = (number of girl juniors)/(number total)
P(A and B) = 3/30
P(A and B) = 1/10
P(A given B) = P(A and B)/P(B)
P(A given B) = (1/10) divided by (9/15)
P(A given B) = (1/10) times (15/9)
P(A given B) = (1*15)/(10*9)
P(A given B) = 15/90
P(A given B) = 1/6
-------------------------------------
Method 2
This method doesn't involve dividing two fractions which could get messy, which is why I find this the easier route. Since we are given the person is a girl, this means we only need to focus on the "girls" column. There are 3 who are juniors out of 4+7+3+4 = 18 total. The probability of selecting a girl junior is 3/18 = 1/6

B.f(x) = 7x - 4
C.f(x) = -4x-1
D. f(x) = x + 7
Answer:
Option A. f(x) = 4x + 7
Step-by-step explanation:
To obtain the answer to the question, we simply try each of the equation using the first two value of x in the table to see which of them will satisfy the table. This is illustrated below:
For option A
1. f(x) = 4x + 7
x = - 1
f(x) = 4(-1) + 7
f(x) = - 4 + 7
f(x) = 3
2. f(x) = 4x + 7
x = 0
f(x) = 4(0) + 7
f(x) = 0 + 7
f(x) = 0
For option B
1. f(x) = 7x - 4
x = - 1
f(x) = 7(-1) - 4
f(x) = - 7 - 4
f(x) = - 11
2. f(x) = 7x - 4
x = 0
f(x) = 7(0) - 4
f(x) = 0 - 4
f(x) = - 4
For Option C
1. f(x) = -4x - 1
x = - 1
f(x) = -4(-1) - 1
f(x) = 4 - 1
f(x) = 3
2. f(x) = -4x - 1
x = 0
f(x) = -4(0) - 1
f(x) = 0 - 1
f(x) = - 1
For Option D
1. f(x) = x + 7
x = - 1
f(x) = - 1 + 7
f(x) = 6
2. f(x) = x + 7
x = 0
f(x) = 0 + 7
f(x) = 7
From the illustrations made above, only option A satisfy the table.

The four variables are
high temp (degrees celsius)kind of precipitation average wind speed (in km/hr)severe weather alertThe two categorical variables are "kind of precipitation" and "severe weather alert". This is because the choices for each of these variables is a list of labels rather than numeric values. We cannot do things like find the average of the kind of precipitation as it doesn't make sense to do so. Each of these categorical variables are also nominal. This means they simply have a label or name. We cannot do things like order the data.

Find the midpoint of the segment with the following endpoints. (6, 4) and (9,9)
Answer:
15/2, 13/2.
Step-by-step explanation:
Here's a graph as well.
Answer in fraction form = (15/2, 13/2)
Answer in decimal form = (7.5, 6.5)
========================================================
Explanation:
To get the midpoint, we average the two endpoint values. We handle the x and y coordinates separately.
The x coordinates of each point are 6 and 9. They average to (6+9)/2 = 15/2 = 7.5; so you add up the x coordinates and divide by 2.
The y coordinates are handled the same way. Add them to get 4+9 = 13 and then divide by 2 to get 13/2 = 6.5
The midpoint is (15/2, 13/2) = (7.5, 6.5)

If a fish experiences an acceleration of 9.8 m/s^2 over a period of 1.4s (It must be falling), then what is its change in velocity?
Answer:
Change In velocity= 13.72 ms^-1
Step-by-step explanation:
fish experiences an acceleration of
9.8 m/s^2 over a period of 1.4s
Change in velocity/time= acceleration
Time in seconds= 1.4 s
Acceleration in meter per second square= 9.8 m/s^2
Change in velocity/time= acceleration
Change In velocity= acceleration*time
Change In velocity= 9.8*1.4(m/s^2 *s)
Change In velocity= 13.72 ms^-1
The angle of elevation to the sun is 24°. What is the length of the shadow cast by a person 1.82 m tall? A. 0.81 m B. 1.99 m C. 4.09 m D. 4.47 m
Answer:
C. 4.09 m
Step-by-step explanation:
Let the length of the shadow cast by a person be x m.
[tex] \tan \: 24 \degree = \frac{height \: of \: person}{length \: of \: the \: shadow} \\ \\ 0.4452286853 = \frac{1.82}{x} \\ \\ x = \frac{1.82}{0.4452286853} \\ \\ x = 4.08778693 \: m \\ x = 4.09 \: m[/tex]
The length of the shadow cast by a person 1.82m tall is 4.99m.
What is the angle of elevation?The angle of elevation is an angle a person's sight is making with the object if he stands in the front of an object.
How to determine the length of the shadow casted?We have been given that the angle of elevation to the sun is 24 degree and the person is 1.82m tall. Then the length of the shadow will be:
tan(24)=1.82/length of the shadow
0.445286853=1.82/length of the shadow
length of the shadow=4.087
=4.09 (approx)
Hence the length of the shadow cast by a person 1.82m tall is 4.09m if the angle of elevation to the sun is 24 degrees.

w = 14/7*8
w = 2*8
w = 16
Answer:
w = 16
Step-by-step explanation:
7 / 8w = 14
multiply both sides by 8:
8 * (7/8w) = 14 * 8

Can u guys PLEASE answer this question ASAP. THIS IS EXTREMELY URGENT. Twenty circular pieces of pastry, each of diameter 4 cm, are cut from a rectangular layer of pastry 20 cm long and 16 cm wide. What is the area, correct to two decimal places, of pastry remaining after the 20 pieces are removed?
Answer:
68,67 cm^2
Step-by-step explanation:
Let's calculate first the total area of pastry that we have.
Let A be that area.
The pastry has rectangular form so its area is:
● A = width × length
The width here is 16 and the length is 20
● A = 20 × 16
● A = 320 cm^2
■■■■■■■■■■■■■■■■■■■■■■■■■■
Let's calculate the are of the 20 pastry circles
Let A' be the area of one circle.
● A' = Pi × r^2
r is the radius wich is the diameter over 2.
● d/2 = 4/2 = 2 cm
● A' = Pi × 2^2
● A' = 4Pi cm^2
The area of 20 pastry circles is 20A'
● 20A'= 20 × 4 × Pi
● 20A'= 80Pi
■■■■■■■■■■■■■■■■■■■■■■■■■■
Let A" be the area of the remaining pastry
● A" = A-20A'
● A" = 320 - 80Pi
● A" = 68.67 cm^2

THE SEVEN APPLEWOMEN
Seven apple women, possessing respectively 20, 40, 60, 80, 100, 120, and 140
apples, went to market and sold all their apples at the same price, and each
received the same sum of money. What was the price?
Answer:
The amount each took home was 20 unit currency.
Step-by-step explanation:
The given parameters are
The number of apples with each of the seven apple women = 20, 40, 80, 100, 120, and 140
The number of apples each woman has can be written in the following formula obtained online which is a series formula
a·n + (n - 1), (a + b)·n + (n - 2), (a + 2·b)·n + (n - 3), (a + 3·b)·n + (n - 4), (a + 4·b)·n + (n - 5), (a + 5·b)·n + (n - 6), (a + 6·b)·n + (n - 7)
Which gives;
a·n + (n - 1) = 20
(a + b)·n + (n - 2)=40
(a + 2·b)·n + (n - 3) = 60
(a + 3·b)·n + (n - 4) = 80
(a + 4·b)·n + (n - 5) = 100
(a + 5·b)·n + (n - 6) = 120
(a + 6·b)·n + (n - 7) = 140
Solving the above system, we get
n = 7, a = 2, b = 3
Which gives
2×7 + 6 = 20
5×7 + 5=40
8×7 + 4 = 60
11×7 + 3 = 80
14×7 + 2 = 100
17×7 + 1 = 120
20×7 + 0 = 140
Whereby all the women sold the apples for the same sum price, based on market pricing if groups of apples are sold at 1 unit currency for 7, and extras are sold for 3 unit currency per extra 1, we have the amount taking home by each of them given as follows;
2×1 + 6×3 = 20
5×1 + 5×3=20
8×1 + 4×3 = 20
11×1 + 3×3 = 20
14×1 + 2×3 = 20
17×1 + 1×3 = 20
20×1 = 20
Therefore, the amount each took home was 20 unit currency.
Marc wants to guess how many marbles are in a box that has a height of 18 inches. He calculates that there are 32 marbles in a height of 5 inches. Approximately how many marbles are in the box?
So every 5 inches in height, there are 32 marbles. You want to know how many marbles there are per 18 inches in height.
[tex]\frac{32}{5} = \frac{x}{18}[/tex]
To get from 5 to 18, you multiply by 3.6.
Do the same thing to the numerator; 32 × 3.6 = 115.2.
Since 0.2 marbles is no marbles, you round down.
There are 115 marbles in the box.
