Triangle ABC is rotated by 135 degrees about point S to create A'B'C' what is the perimeter of ABC
Answer: 12.9
Step-by-step explanation:
5.1 + 2 + 5.8 = 12.9
The perimeter of the triangle ABC is 12.9 units.
What is the perimeter of a triangle?The perimeter of a triangle is the sum of length of three sides of the triangle.
Given, the triangle ABC is rotated by 135 degrees about point S to create the triangle A'B'C'.
We know, after rotation of a figure, the whole dimension of the figure remains the same.
Therefore, AB = A'B' = 5.1 units
BC = B'C' = 2 units
CA = C'A' = 5.8 units
Hence, the perimeter of the triangle ABC
= (5.1 + 2 + 5.8) units
= 12.9 units

12. The perimeter of a rectangle is 50 feet. The width is 5 less than the
length. What are the dimensions of the rectangle? (Write your answer as
Length, Width)
Step-by-step explanation:
Length = x
Width = (x-5)
Perimeter = 2 lengths + 2 widths
50 ft = x + x + (x-5) + (x-5)
50 ft = 4x - 10
60 ft = 4x
15 ft = x
length = x = 15 ft
width = (x-5) = (15 -5) = 10 ft
dimensions = length × width
= 15 ft × 10 ft
if you wanna check,
50 ft = x + x + (x-5) + (x-5)
50 ft = 15 + 15 + (15-5) + (15-5)
50 ft = 30 +(10+10)
50 ft = 30 + 20
50 ft = 50

Answer: S = P600 × n
Step-by-step explanation:
Amount earned per day = P600
Number of days used = n
The total salary s, will be the value of p600 multiplied by n. This will be:
= P600 × n
Therefore, the function regarding the total salary, s will be: P600 × n

The value of [b] if a = 1/8 and c = 4 will be 33/16.
What is the mean of two numbers?
The mean of two numbers [a] and [b] is -
[M] = (a + b)/2
Given is that a = 1/8 and c = 4.
We have the following values -
a = 1/8
c = 4
Therefore, we can write the value of [b] as -
b= (1/8 + 4)/2
b = (33/8)/2
b = 33/8 x 1/2
b = 33/16
Therefore, the value of [b] if a = 1/8 and c = 4 will be 33/16.

On Monday, Jayla raised $30 and Carlos raised $50.
After that, Jayla raised $12 per day and Carlos
raised $7 per day. After how many days will they
have raised the same amount?
They will raise the same amount after days.
Answer:
84 days
Step-by-step explanation:
You would use the LCM to solve this.
12 and 7 don't share any common factors other than 1,
so you would multiply 12 x 7, which gets you 84.
After 84 days they would have raised the same amount.

you pay a processing fee and a daily fee to rent a beach house. the table shows the total cost of renting the beach house for different numbers of days.
a) what is the processing fee? the daily fee?
b) you can spend no more than $1200 on the beach house rental. what is the maximum number of days you can rent the beach house?
Answer:
a) The daily fee is $102
The processing fee is $42
b) The maximum number of days the beach house can be rented with no more than $1,200 is (by rounding down) 11 days
Step-by-step explanation:
The data given in the table are as follows;
Number of days (t) [tex]{}[/tex] Total cost, T (dollars)
2 [tex]{}[/tex] 246
4 [tex]{}[/tex] 450
6 [tex]{}[/tex] 654
8 [tex]{}[/tex] 858
Whereby, we have that the processing fee is P, and the daily fee is D, we can write;
Total cost, T = D × t + P
From the table, we have;
When t = 2 days and T = $246, the above equation for total cost becomes;
$246 = D × 2 + P = 2·D + P
246 = 2·D + P.....(1)
Similarly, when t = 6 days, and T = $654, we have;
$654 = D × 6 + P = 6·D + P
654 = 6·D + P.....(2)
Subtracting equation (1) from equation (2) gives;
654 - 246 = 6·D + P - (2·D + P)
408 = 4·D
D = 408/4 = 102
The daily fee, D = $102
From equation (1), we have;
246 = 2·D + P = 2 × 102 + p
p = 246 - 2 × 102 = 42
P = $42
The processing fee, P = $42
b) Given that the maximum amount available (total amount) for spending on the beach house rental = $1200, we have;
T = D × t + P
Where, D = $102 and P = $42 are constants and T = $1,200, we have;
1,200 = 102 × t + 42
t = (1200 - 42)/102 ≈ 11.35 days
Given that we can only rent the beach house for a whole number of days, the number of days the beach house can be rented is therefore, by rounding down, t = 11 days.
a) D = $102
P = $42
b) t = 11 days
Step-by-step explanation:
Given :
Data in the table -
Days (t) Total cost (dollors) (T)
2 246
4 450
6 654
8 858
Calculation :
a) Let the total processing fee is P and the daily fee is D.Now,
[tex]\rm T = D \times t + P[/tex] ------------ (1)
Now, from the table we have ,
When t = 2 days and T = $246 than equation (1) becomes
[tex]\rm 246 = D\times 2+ P = 2D + P[/tex]
246 = 2D + P ------- (2)
Similarly, when t = 6 days, and T = $654, then equation (1) becomes
[tex]\rm 654 = D\times 6+ P = 6D + P[/tex]
654 = 6D + P --------- (3)
Subtracting equation (2) from equation (3) ,
654 - 246 = 6D + P - (2·D + P)
408 = 4D
D = $102
From equation (2),
246 = 2·D + P = 2 × 102 + p
p = 246 - 2 × 102 = 42
P = $42
b) Given:
The maximum amount available for spending on the beach house rental = $1200
Now,
[tex]\rm T= D\times t + P[/tex]
Where, D = $102 and P = $42 are constants and T = $1,200,
1200 = 102t + 42
t = 11.35 days
Given that we can only rent the beach house for a whole number of days. therefore, the number of days the beach house can be rented is, t = 11 days.
