danny is installing a fence around his rectangular yard. His yard is 20feet by 45feet. If the fence cost 25 per foot based on the area what is the cost?
Answer: Find the perimeter of the yard ( the distance around the yard).
A rectangle has two sides of each dimension.
The perimeter is 20 + 20 + 45 + 45 = 130 feet.
Now multiply the total feet by the cost per foot:
130 feet x 25 per foot = $3,250 total.
Step-by-step explanation:
Answer:
$225
Step-by-step explanation:
The area to be fenced in is 20 ft by 45 ft, or 900 ft^2. But "25 per foot based on the area" is illogical. Please ensure that you have copied this problem down accurately, and be sure to provide units of measurement: did you mean $25 per square foot, or per foot, or what?
The fencing cost is usually dependent on the unit cost and the length of the yard perimeter. The perimeter is P = 2L + 2W, which here is P = 2(45 ft) + 2(20 ft), or 130 ft. If the fencing is 25 cents per foot, $130 ft of fencing would come to $32.50.

Milan is participating in a 4-day cross-country biking challenge. He biked for 48, 51, and 59 miles on the first three days. How many miles does he need to bike on the last day so that his average (mean) is 55 miles per day?
Answer:
62 miles
Step-by-step explanation:
The formula for average is given as
Sum of values / Number of values
Let x = miles on the last day
Hence
48 + 51 + 59 + x/4 = 55
Cross Multiply
= 158 + x = 220
x = 220 - 158
x = 62
Therefore, he needs to bike 62 miles on the last day so that his average (mean) is 55 miles per day.

If the card above is the product of Emily's and Ros's ages, state their ages, respectively.
Answer:
Given expression:
xy + 3x + 8y + 24You may factor this as follows:
xy + 8y + 3x + 24 = y(x + 8) + 3(x + 8) = (x + 8)(y + 3)We have the product of x + 8 and y + 3 and we can state that:

5. An extension ladder is extended 32 feet to rest
against a wall. The bottom of the ladder is 6 feet
from the base of the wall, as shown.
32 ft.
Which of the following is closest to the distance
from the top of the ladder to the base of the wall?
Answer:
Option A
Step-by-step explanation:
As shown in the figure ABC,
AC = Length of the ladder
BC = Distance between the base of the ladder and the wall
AB = Distance from the top of the ladder and the base of the wall
By applying Pythagoras theorem in the given right triangle ΔABC,
AC² = AB² + BC²
(32)² = h² + (6.5)²
h² = 1024 - 42.25
h = √(981.75)
h = 31.33
h ≈ 31 feet
Therefore, Option A will be the correct option.

A stereo normally priced at $690 is on sale for 20% off. Find the discount and the sale price.
Answer:
Discount = $138
Sale price = $552
Step-by-step explanation:
Discount = 20% of 690
Sale price = 100% - 20% = 80% of 690
Discount)
20% = 0.2
0.2 x 690 = 138
Discount = $138
Sale price)
Method 1:
80% = 0.8
0.8 x 690 = 552
Sale price = $552
Method 2:
We know the discount = $138
So subtract the discount from the original price:
690 - 138 = 552
Sale price = $552.

Mr. Ramirez purchased 20 concert tickets for a total of $225. The concert tickets cost $15 for adults and $10 for children under the age of 12.
Part A: Which system of equations represents the given scenario? Let a represent adults and c represent children.
A.10a + 15c = 20
a + c = 225
B.10a + 15c = 225
a + c = 20
C.15a + 10c = 225
a + c = 20
D.15a + 10c = 20
a + c = 225
Part B: What is the solution to the system of equations?
A.5 adults and 15 children
B.10 adults and 10 children
C.15 adults and 5 children
D.9 adults and 9 children
Answer:
Part A) C
Part B) A
Step-by-step explanation:
For part B I solved for a (adults) which then I got 5
I will attach an image of my work for part b
sorry for the poor quality picture
The system of equations that represents the given scenario is a + c = 20, 15a + 10c = 225 and the solution to the system of equations is a = 5 (adults) and c = 15 (children).
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let a represent the number of adult tickets and c represent the number of children's tickets.
The total number of tickets purchased is 20, so we have:
a + c = 20
The cost of an adult ticket is $15 and the cost of a children's ticket is $10. The total cost of the tickets is $225, so we have:
15a + 10c = 225
Therefore, the system of equations that represents the given scenario is:
a + c = 20
15a + 10c = 225
Now let us solve a and c values by using substitution method.
a=20-c
Now substitute in equation 15a + 10c = 225
15(20-c)+ 10c = 225
300 - 15c + 10c = 225
-5c = -75
c = 15
Substituting c = 15 into the first equation, we get:
a + 15 = 20
a = 5
Therefore, the system of equations that represents the given scenario is
a + c = 20, 15a + 10c = 225 and the solution to the system of equations is a = 5 (adults) and c = 15 (children).

help!!! Find the lateral surface area of
the following square pyramid:
Given:
A square base pyramid with base length 6 cm and the slant height is 4 cm.
To find:
The lateral surface area of the given square pyramid.
Solution:
The lateral surface area of the given square pyramid is equal to the areas of 4 congruent triangles with base 6 cm and height 4 cm.
Area of a triangle is:
[tex]Area=\dfrac{1}{2}\times base\times height[/tex]
So, the area of one triangle or one side of the given pyramid is:
[tex]A_1=\dfrac{1}{2}\times 6\times 4[/tex]
[tex]A_1=\dfrac{24}{2}[/tex]
[tex]A_1=12[/tex]
Now, the lateral surface area of the given square pyramid is 4 times the area of one triangle.
[tex]LA=4A_1[/tex]
[tex]LA=4(12)[/tex]
[tex]LA=48[/tex]
Therefore, the lateral surface area of the given square pyramid is 48 cm².

Answer:
the motion of the object will stay the same
Step-by-step explanation:
Find the point that partitions segment AB in a 2: 1 ratio.
Please don't give me a link to a file, because it doesn't work for me.
The point that partitions segment AB in a 2: 1 ratio is point (5,19/3).
Suppose the point that partitions segment AB in a 2: 1 ratio is point (x,y)
What is the internal division formula?
The internal division formula for a line segment is given by:
[tex]x=\frac{m_1x_2+m_2x_1}{m_1+m_2}[/tex]
[tex]y=\frac{m_1y_2+m_2y_1}{m_1+m_2}[/tex]
Where (x₁,y₁) and (x₂,y₂) are endpoints of the line segment.
Coordinates of points A≡(1,3)
Coordinates of points B≡(7,8)
[tex]x=\frac{2*7+1*1}{1+2}[/tex]
[tex]x=5[/tex]
Similarly, [tex]y=\frac{19}{3}[/tex]
So (x,y)≡(5,19/3)
Hence, the point that partitions segment AB in a 2: 1 ratio is point (5,19/3).
