Answer:

A conjecture is an “educated guess” that is based on examples in a pattern. ... However, no number of examples can actually prove a conjecture. It is always possible that the next example would show that the conjecture is false. A counterexample is an example that disproves a conjecture.

Answer:

Step-by-step explanation:

d= 25 yards ;   r = 25/2 = 12.5 yards

circumference of two semicircle = circumference of circle

=  2πr = 2*3.14*12.5 = 78.5 yards

Perimeter of school truck  = 78.5 + 85 + 85 = 248.5 yards

Distance traveled by  Jasmine = 3* 248.5 = 745.5 yards

Answer:

The missing output value is:

                             9

Step-by-step explanation:

The function in terms of the variable x, where x represents  the input value is given by the formula:

where F(x) is the output value corresponding to the input value x.

We are asked to find the missing output value i.e. we are asked to find the value of F(x) at x=5.

i.e. we have:

          Hence, the missing output value is: 9

Answer:

9

Step-by-step explanation:

(5)+4=9

The cost per book is $3.41 thus the cost of buying 7 books will be $23.87 maintaining the given ratio.

What are the ratio and proportion?

The ratio is the division of the two numbers.

Proportion is the relation of a variable with another. It could be direct or inverse.

For example, a/b, where a will be the numerator and b will be the denominator.

As per the given,

The book fair had a sale where 6 books were $20.46.

Cost per book = 20.46/6 = $3.41

To buy 7 books,

The cost of buying 7 books at $3.41 per book will be,

⇒ 3.41 × 7 = $23.87

Hence "The cost per book is $3.41 thus the cost of buying 7 books will be $23.87 maintaining the given ratio".
