The length of swimming course is 345.93 meters.
Step-by-step explanation:
Given,
BC = 80 m
AB = 145 m
Using pythagoras theorem to find AC.
[tex]AC^2+BC^2=AB^2\\AC^2+(80)^2=(145)^2\\AC^2+6400=21025\\AC^2=21025-6400\\AC^2=14625[/tex]
Taking square root on both sides
[tex]\sqrt{AC^2}=\sqrt{14625}\\AC=120.93m[/tex]
Length of swimming course = AB + BC + AC
Length of swimming course = 145 + 80 + 120.93 = 345.93 m
The length of swimming course is 345.93 meters.

let g (x) = 3x+2 and f (x) = x-2 / 3 find the value. g (f(2))
A. 1
B. 0
C. 2
D. 1/3
Answer: OPTION C.
Step-by-step explanation:
In order to solve the given exercise, you can follow these steps:
1. Given the following function f(x):
[tex]f(x)=\frac{x-2}{3}[/tex]
You must substitute [tex]x=2[/tex] into the function f(x). Then:
[tex]f(2)=\frac{(2)-2}{3}[/tex]
2. Evaluating, you get:
[tex]f(2)=\frac{0}{3}\\\\f(2)=0[/tex]
3. Now, the next step is to substitute [tex]f(2)[/tex] into the function g(x):
[tex]g (x) = 3x+2\\\\g (f(2)) = 3(0)+2[/tex]
4. Finally, evaluating, you get the following result:
[tex]g (f(2)) = 0+2\\\\g (f(2)) =2[/tex]
You can identify that it matches with the Option C.
To find the value of g(f(2)), we first calculate f(2) which equals 0, then we substitute that into g(x) to get g(0) which equals 2. Therefore, g(f(2)) is 2.
Explanation:The question asks for the value of g(f(2)) given two functions g(x) = 3x + 2 and f(x) = (x - 2) / 3. To find the value, we first evaluate f(2), and then plug that result into g(x).
First, we evaluate f(2): f(2) = (2 - 2) / 3 = 0 / 3 = 0.Next, we use this result in g(x): g(f(2)) = g(0) = 3(0) + 2 = 0 + 2 = 2.The answer to the given function composition g(f(2)) is 2, which corresponds to option C.

if 3x= 27, then x = 9 what algebraic property?
Division property of equality is used
Solution:
Given that,
If 3x = 27 then x = 9
We have to find the algebraic property used here
Division property is used here
The division property of equality is a property that tells us if we divide one side of an equation by a number, we must also divide the other side by the same number so that our equation stays the same.
Given equation is:
3x = 27
Divide both the sides by 3
[tex]\frac{3x}{3} = \frac{27}{3}\\\\x = 9[/tex]
Thus division property of equality is used
The algebraic property used in changing 3x = 27, to x = 9 is the Division Property of Equality. This property means that if both sides of an equal equation are divided by the same nonzero number, then the resulting equation remains true.
Explanation:The algebraic property that applies when rearranging the equation 3x = 27, to x = 9 is known as the Division Property of Equality. This property states that when both sides of an equation are divided by the same nonzero number, the result is an equivalent equation.
To demonstrate this, in the given equation 3x = 27 we can apply the Division Property of Equality by dividing both sides of the equation by 3. This will give: 3x/3 = 27/3 which simplifies to x = 9, thus demonstrating the division property of equality.

Alfred does chores to earn money in the summer. The table
shows the amount he earns per chore. Alfred weeded the
garden 6 times over the summer. Write and solve a division
equation to find how much he earned weeding the garden.
The correct answer is (C) $48. Hence the correct option is c.
1. Identify the relevant information:
From the table, we know Alfred earns $8 per time he weeds the garden.
He weeded the garden 6 times.
2. Calculate his total earnings from weeding:
To find the total amount Alfred earned, we multiply the amount he earns per weeding session by the number of times he weeded:
Total earnings = Number of times weeded * Earnings per weeding
Total earnings = 6 times * $8/time = $48
Therefore, Alfred earned $48 from weeding the garden.
Hence the correct option is c.
Complete question:
Alfred does chores to earn money in the summer. The table shows the amount he earns per chore.
Chore Amount Earned ($)
mow lawn $10
wash car $5
weed garden $8
Suppose Alfred weeded the garden 6 times in the summer. How much did he earn weeding?
(A) $30
(B) $60
(C ) $48
(D) $75
The answer is option B - $48. Alfred earned $48 from weeding the garden 6 times, as each weeding earned him $8 and $8 multiplied by 6 gives $48.
The question involves a basic arithmetic calculation to determine how much money Alfred earned for weeding the garden multiple times. We need to multiply the amount Alfred earns per instance of weeding by the number of times he performed the task.
Given that Alfred earns $8 for weeding the garden once and he weeded the garden 6 times over the summer, the total earning from weeding can be calculated as:
Amount Earned Weeding = Earned per Weeding × Number of Weedings
Amount Earned Weeding = $8 × 6 = $48
Therefore, Alfred earned $48 from weeding the garden 6 times in the summer.
The question is:
Alfred does chores to earn money in the summer. The table shows the amount he earns per chore.
Chore Amount Earned ($)
mow lawn $10
wash car $5

The measures of two complementary angles are complementary angles are in the ratio 1:3. What are the measures of the angles?
The measure of angles are 22.5 degree and 67.5 degree
Solution:
Given that, measures of two complementary angles are in ratio 1 : 3
one angle : another angle = 1 : 3
Let the first complementary angle 1x
Let the another complementary angle be 3x
If the angles are complementary, then their sum is 90 degrees
Therefore,
1x + 3x = 90
4x = 90
x = 22.5
Then, first angle = 1x = 1(22.5) = 22.5
Another angle = 3x = 3(22.5) = 67.5
Thus the measure of angles are 22.5 degree and 67.5 degree

y = 5x - 17
y = 5x - 13
y = 5x + 13
y = 5x + 17
Answer:
y = 5x - 17
Step-by-step explanation:
y = mx + c
m = the gradient/slope = 5
y = 5x + c
Substitute (3, -2) into the equation above to find c.
-2 = 5(3) + c
-2 = 15 + c
-2 - 15 = c
-17 = c
y = 5x - 17
Answer:
Step-by-step explanation:
point(3, -2) and has a slope of 5
Slope m = 5
y1 = -2 and x1 = 3
The equation is
y - y1 = m(x - x1)
y + 2 = 5(x - 3)
y + 2 = 5x - 15
y = 5x - 15 - 2
y = 5x - 17

Which expression is equivalent to |b|>2 ?
b > –2 and b < 2
b < –2 or b > 2
b < –2 and b > 2
b > –2 or b < 2
Answer:
b < –2 or b > 2
Step-by-step explanation:
The given expresion is
[tex] |b| \: > \: 2[/tex]
By the definition of absolute value function.
|x|=x, if x>0
|x|=-x, if x<0
This implies that:
[tex] b \: > \: 2 \: or \: - b \: > \: 2[/tex]
Divide the second inequality by -2 and reverse the sign
[tex]b \: > \: 2 \: or \: b \: < \: - 2[/tex]
Option B is correct
The expression |b| > 2 is equivalent to b < -2 or b > 2, indicating that the value of b is either greater than 2 or less than -2.
The expression |b| > 2 is equivalent to the situation where b is greater than 2 or less than -2. The absolute value sign indicates the distance of b from 0 on a number line, without considering direction. Therefore, if |b| is greater than 2, b must lie outside the interval from -2 to 2, since anything within that interval would have an absolute value less than or equal to 2.
This means that the correct expression equivalent to |b| > 2 is b < -2 or b > 2. When b is positive, it must be greater than 2 to satisfy the inequality. When b is negative, to have an absolute value greater than 2, it must be less than -2.

A six pack of soda costs 3.48 how much does each bottle of soda cost
Final answer:
To determine the cost of each bottle in a $3.48 six pack of soda, divide the total cost by the number of bottles, which results in each bottle costing $0.58.
Explanation:
To find out how much each bottle of soda costs when a six pack of soda costs $3.48, we need to divide the total cost by the number of bottles in a pack. Since there are six bottles in a six pack, we take the total cost of $3.48 and divide it by 6.
The calculation will look like this:
Cost per bottle = Total cost of six pack ÷ Number of bottles
Cost per bottle = $3.48 ÷ 6
Cost per bottle = $0.58
Therefore, each bottle of soda costs $0.58.
Which statement correctly describes the solution to the equation below?
-4[x+2]+x= 3x - 8 - 5x
A There is no solution to this equation.
B There are infinitely many solutions to this equation.
C There is exactly one solution to this equation, and the solution is 0 .
D There is exactly one solution to this equation, and the solution is -1 .
Answer:
Option C) There is exactly one solution to this equation, and the solution is 0 is correct
That is the solution x=0
Step-by-step explanation:
Given equation is -4(x+2)+x=3x-8-5x
To find the solution to the given equation :
First to solve the given equation
-4(x+2)+x=3x-8-5x
-4x-8+x=3x-8-5x ( by using the distributive property )
-3x-8=-2x-8 ( adding the like terms )
-3x-8-(-2x-8)=-2x-8-(-2x-8)
-3x-8+2x+8=-2x-8+2x+8 ( adding the like terms )
-x=0
Therefore x=0 is the only solution to the given equation
Option C) There is exactly one solution to this equation, and the solution is 0 is correct
That is the solution x=0
After simplifying and solving the given equation, it is clear that the single solution is x = 0, which corresponds to option C.
To identify the correct statement describing the solution to the given equation, we need to solve the equation step by step:
-4[x+2]+x = 3x - 8 - 5x.
First, distribute the -4 across the terms inside the brackets:
-4x - 8 + x = 3x - 8 - 5x.
Combine like terms:
-3x - 8 = -2x - 8.
Then add 3x to both sides:
-8 = x - 8.
Finally, add 8 to both sides to solve for x:
x = 0.
The equation simplifies to x = 0, which means there is a single solution to this equation. Therefore, the correct option is: C. There is exactly one solution to this equation, and the solution is 0.
