Answer:

A, (1, 3+1/2)

Step-by-step explanation:

Midpoint formula for reference: m= {(x1 + x2)/2, (y1 + y2)/2}

Plugging in the points we get: m= {(8 - 6)/2, (5 + 2)/2}

Now we simplify using PEMDAS. First step is parentheses.

m= {2/2, 7/2}

Simplifying again (and making 7/2 a mixed number), it becomes

m= {1, 3+1/2}

Applying the slope formula, the value of the missing coordinate is: r = 13.

The slope of a line is described as the steepness of the line, which is the ratio of the rise to the run of the line on a coordinate plane.

The formula for finding the slope of a line is:

Slope (m) = y2 - y1/x2 - x1

Given the following:

Slope of a line (m) = 1/4

(-3, 2) = (x1, y1)

(r, 6) = (x2, y2)

Plug in the values and find r using the slope formula

1/4 = (6 - 2)/(r - (-3))

1/4 = 4/(r + 3)

Cross multiply

1(r + 3) = (4)4

r + 3 = 16

r + 3 - 3 = 16 - 3

r = 13

Therefore, applying the slope formula, the value of the missing coordinate is: r = 13.

Answer: 48 in^2

Step-by-step explanation:

Let's solve each shape

1. The first shape is a rectangle; take 5 times 2 = 10 in^2

2. The second shape is a square; take 2 times 2 = 4 in^2

We see that there are 4 rectangles and 2 squares.

So, we take 10 times 4 = 40 in^2

Then we take 4 times 2 = 8 in^2

Then we add 40 with 8 = 48 in^2

Therefore , the solution of the given problem of ordered pair comes out to be the ordered pair (1, 1/2).

"Ordered pairs" are two separate variables that are arranged in a way that suggests a specific sequence. The coordinates for x and y in an order pair are represented, respectively, by the main and second components. The sample following uses close parentheses to indicate the ordered combination.

Here, The formulae are as follows:

=>y = -z + 2      ...(1)

=> y = -2x² + z + 1  ...(2)

Equation (1) can be substituted for equation (2) to find the value of z:

=> Z = x² + 1/2 - z + 2 = -2x² + z + 1

=> 2z = 2x² + 1

We can now enter this value of z into equation (1) and find the value of y:

=> y = -z + 2

=> y = -(x² + 1/2) + 2

=> y = -x² + 3/2

As a result, the equation system can be expressed as:

=> z = x² + 1/2

=> y = -x² + 3/2

When x=0:

=> z = 0² + 1/2 = 1/2

=> y = -0² + 3/2 = 3/2

Therefore, there is no answer for the ordered pair (0, 3/2).

When x=1:

=> z = 1² + 1/2 = 3/2

=> y = -1² + 3/2 = 1/2

The answer is the ordered pair (1, 1/2).

To display the terms in the Fibonacci sequence, starting with Fib(0) and continuing as long as the terms are less than 10,000, a program is written with a loop construct. This loop is implemented using a `while` loop with a header line that looks like this: `while term < 10000:`.

Fibonacci sequence is named after the Italian mathematician Leonardo Fibonacci who developed a mathematical sequence in the 13th century to explain the geometric growth of a population of rabbits.

The first two terms in this sequence, Fib(0) and Fib(1), are 0 and 1, and every subsequent term is the sum of the preceding two.

The first several terms in the Fibonacci sequence are:

Fib(0) = 0, Fib(1) = 1, Fib(2) = 1, Fib(3) = 2, Fib(4)= 3, Fib(5)=5.

This program continues as long as the value of the term is less than the maximum

The output is as follows:

```1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 2584 4181 6765```

The while loop could also be used to achieve the same goal.

Thomas family has 4 adults and 3 children. Let's say there are 'a' adults and 'c' children in the Thomas family.
According to the given information, the cost of a 7-day holiday in Eastbourne for one adult is 289p and for one child is 176p.

So, the total cost for the Thomas family is:
Total cost = (Cost per adult x Number of adults) + (Cost per child x Number of children)
1571p = (289p x a) + (176p x c)
We have two variables and two equations, so we can solve for 'a' and 'c' simultaneously using substitution or elimination.
Let's use substitution method here:
From the second equation, we can rearrange it to find:
c = (1571p - 289p x a) / 176p
Now, we can substitute this value of 'c' into the first equation and solve for 'a':
1571p = (289p x a) + (176p x [(1571p - 289p x a) / 176p])
Simplifying this equation:
1571p = 289p x a + 1571p - 289p x a
0 = 0
This means that 'a' can take any value, and the number of children can be calculated using the equation we found earlier. Let's simplify that equation:
c = (1571p - 289p x a) / 176p
c = (1571 - 289a) / 176
Now, we can plug in some values of 'a' to find the corresponding value of 'c':
When a = 1, c = (1571 - 289) / 176 = 8.3 (not a whole number)
When a = 2, c = (1571 - 578) / 176 = 6.5 (not a whole number)
When a = 3, c = (1571 - 867) / 176 = 4.6 (not a whole number)
When a = 4, c = (1571 - 1156) / 176 = 2.7 (not a whole number)
When a = 5, c = (1571 - 1445) / 176 = 0.6 (not a whole number)
When a = 6, c = (1571 - 1734) / 176 = -2.2 (not a valid answer)
So, the only valid answer is when a = 4 and c = 2.7 (rounded up to 3).
Therefore, the Thomas family has 4 adults and 3 children.

Let the total  length of the post be x m

Then length of post in mud= x/2

​Length of post in water = x/3

Given

x/2-x/3=10/3

x/6=10/3

x=20

​

Answer:

20 m

Step-by-step explanation:

Given:

Let x be the length of the lamp post.

Convert 3 ¹/₃ to an improper fraction:

\(\sf \implies 3 \frac{1}{3}=\dfrac{3 \times 3+1}{3}=\dfrac{10}{3}\)

The total length of the lamp post (x) is the sum of the three given lengths:

\(\implies \sf mud+water+above\: water=x\)

\(\sf \implies \dfrac{x}{2}+\dfrac{x}{3}+\dfrac{10}{3}=x\)

Multiply both sides by 6:

\(\sf \implies \dfrac{6x}{2}+\dfrac{6x}{3}+\dfrac{6 \cdot 10}{3}=6x\)

\(\sf \implies 3x+2x+20=6x\)

\(\sf \implies 5x+20=6x\)

Isolate x:

\(\sf \implies 20=6x-5x\)

\(\implies \sf x=20\)

Therefore, the whole length of the post is 20 m.

Step-by-step explanation:

Question 1:  Assumption: This is a 30-60-90 triangle.

Remember that the sides of a 30-60-90 triangle are in the ratio 1:√3:2

The side opposite the 90° angle is 16, so the side opposite the 30° angle is 16/2 =  8

x = 8 units.

Question 2:  Assumption: This is an isosceles triangle.

Draw the altitude to the vertex angle and you get a 30-60-90 triangle.

The side opposite the 90° angle has length 22, so the side opposite the 30° angle has length 11.

x/2 = 11

x = 22 units

Question 3:  Assumption: This is a 45-45-90 triangle.

The sides of a 45-45-90 triangle are in the ratio 1:1:√2

The sides opposite the 45° angles are 19 and x.

x = 19

Answer:

1.3 inches

Step-by-step explanation:

1. Determine what you already know in order to set up the equation:

1 inch = 100 miles

x inches = 130 miles

Solving for x

2. Set up the equation so both numerators are the same unit (In this case, both numerators are the mile values and both denominators are the inch values.)

\(\frac{100}{1}\) = \(\frac{130}{x}\)

3. Cross multiply (Multiply the first fraction's numerator by the second fraction's denominator, and vice versa. It doesn't matter which number is on which side of the = sign.)

100x = 130

4. Divide each side by 100 to isolate the variable.
