The sum of two prime numbers is 85. What is the product of these two prime numbers?

1 answer:

6 0

Observe that 85 is an odd number. That means, one of the prime numbers must be even to have an odd sum with another odd number. As we know, the only even prime number is 2. Hence, the other number is 83. So, the product of these two prime numbers is 83 x 2 = 166. Thus, the answer is 166.

Which of the following steps is included in the construction of a perpendicular line through a point on a line?

Molodets [167]

Answer:

Connect arcs that are above the original line with a straightedge ⇒ 2nd

Step-by-step explanation:

* Lets revise how to construct a perpendicular line through a point

on the line

- Given: line AB and point P lies on it

1. Place your compass pin at P and draw an arc of any size below

AB that crosses the line twice at points C and D

2. Stretch the compass to a larger distance

3. Place the compass pin on point C and draw a small arc above

the line

4. Without changing the distance of the compass place the

compass pin on point D and draw another small arc intersects

the small arc from C at point E

5. Using a straightedge, to join P which is on the original line and E

which is the intersection point of the two small arcs above the

original line, then PE is perpendicular to AB at E

- From the steps up the step is including in the construction of a

perpendicular line through a point on a line is:

Connect arcs that are above the original line with a straightedge

* Remember:

- The step of Connect arcs that are above and below the given line

with a straightedge is in the construction a perpendicular from a

point off the line

- The step of Create arcs on either side of a point that is off the

given line is in the construction of a perpendicular bisector

of a line

- The step of Create a copied angle by using the first two lines as the

original angle in the construction of the parallel lines

- Look to the attached figure to help you

Step-by-step explanation:

(.5)^2(.5)^1= .125

Where (.5)^2 is the probability two mice turn left multiplied by (.5) that one of them turns right.
