Answer:

-15

Step-by-step explanation:

3 x 5 = 15

when negative numbers are multiplied by positive numbers the product will be negative.

Final answer:

The product of -3 and 5 is -15, as per the multiplication rules where a negative number multiplied by a positive number results in a negative product.

Explanation:

The product of -3 and 5 is -15. In mathematics, when we talk about the product of two numbers, we are referring to the result of multiplying them. According to multiplication rules, when two numbers have opposite signs, the product has a negative sign. If we multiply a negative number by a positive number, the answer will also have a negative sign.

It's important to remember that multiplication is commutative, meaning that changing the order of the numbers does not change the product. The key concepts are similar to those used when figuring out subtraction and addition of signed numbers. For example, subtracting a negative is the same as adding a positive.

If we apply this to -3 multiplied by 5, we multiply the absolute values (3 and 5) to get 15. Since we have one positive number (5) and one negative number (-3), our final product is -15.

Answer:

(-4,17)

Step-by-step explanation:

2x-3y=-11

2x+y=9

solve the equation

x=-4

2x+y=9

substitute the value of x into an equation

2×(-4)+y=9

solve the equation

y=17

A possible solution is

(-4,17)

check the solution

2×(-4)-3=-11

2×(-4)+17=9

simplify

-11=-11

9=9

the order pair is a solution

answer is (-4,17)

To solve the given system using the substitution method, solve the second equation for y, substitute into the first equation, and solve for x. Substituting x back into the expression for y gives the solution x = 2 and y = 5.

To solve the system of equations using the substitution method, we have to express one variable in terms of another from one of the equations and then substitute it into the other equation. For the given system of equations:

First, we solve the second equation for y:

y = 9 - 2x

Now we substitute this expression for y into the first equation:

2x - 3(9 - 2x) = -11

2x - 27 + 6x = -11

8x - 27 = -11

8x = 16

x = 2

After finding x, we can substitute x back into y = 9 - 2x to find the value of y:

y = 9 - 2(2)

y = 9 - 4

y = 5

The solution to the system of equations is x = 2 and y = 5.

Step-by-step explanation:

Answer:

0.785398163 rad

Step-by-step explanation:

The value of arctan(1) is equal to π/4 or 45 degrees.

The tangent of an angle is defined as the ratio of the length of the opposite side to the length of the adjacent side in a right triangle.

For the angle whose tangent is 1, we can visualize a right triangle where the length of the side opposite to the angle is 1 and the length of the adjacent side is also 1.

Using the Pythagorean theorem, we can calculate the length of the hypotenuse:

hypotenuse² = opposite² + adjacent²

hypotenuse² = 1² + 1²

hypotenuse² = 1 + 1

hypotenuse² = 2

hypotenuse = √2

Now, we can use the definition of the arctan function to find the angle whose tangent is 1:

arctan(1) = angle whose tangent is 1 = angle whose opposite side is 1 and adjacent side is 1

This angle is a well-known special angle in trigonometry.

It is a 45-degree angle (π/4 radians) or a quarter of a full circle.

Therefore, arctan(1) is equal to π/4 or 45 degrees.

Answer:

A rule of polygons is that the sum of the exterior angles always equals 360 degrees. Since it is a regular octagon, so each of the interior angles of octagon are equal. ((n-2)*180)/n where n is the number of sides of the polygon.for example in case n=8 for an octagon, so we get:

((8-2)*180)/8 => (6*180)/8 => 1080/8 = 135 degrees. This means that each interior angle of the regular octagon is equal to 135 degrees.  

Each exterior angle is the supplementary angle to the interior angle at the vertex of the polygon, so in this case each exterior angle is equal to 45 degrees. (180 - 135 = 45). Remember that supplementary angles add up to 180 degrees.  

And since there are 8 exterior angles, we multiply 45 degrees * 8 and we get 360 degrees.

This technique works for every polygon, as long as you are asked to take one exterior angle per vertex.

The sum of the exterior angles of any polygon, including an octagon, is always 360 degrees. This is true regardless of the polygon's number of sides, because when one traces around the polygon, the point will have made one full revolution, or 360 degrees.

In mathematics, the sum of the exterior angles of any polygon, not just an octagon, is always 360 degrees. This applies regardless of the number of sides the polygon has. The concept comes from observing how a point moves as one traces around the polygon: during the complete circuit, it will have made exactly one full revolution, which is 360 degrees in total. Just as a circle consists of 360 degrees, this concept applies to polygons and their exterior angles as well.

(a) Jason arrives at the factory first

(b) It takes 5 minutes until the other person arrives

Step-by-step explanation:

Jason and Jeremy work together at a juggling-ball factory

We need to know who arrives at the factory first and how long it is until the other person arrives

Time = Distance ÷ speed

∵ Jason lives 25 miles away from the factory

∴ The distance = 25 miles

∵ He drives at 60 miles per hour

∴ The speed = 60 miles per hour

- Use the rule above to find the time

∵ Time = 25 ÷ 60 = [tex]\frac{5}{12}[/tex] hour

∵ 1 hour = 60 minutes

∴  [tex]\frac{5}{12}[/tex] hour =  

∴ Jason arrives to the factory in 25 minutes

∵ Jeremy lives 35 miles away from the factory

∴ The distance = 35 miles

∵ He drives at 70 miles per hour

∴ The speed = 60 miles per hour

- Use the rule above to find the time

∵ Time = 35 ÷ 70 = [tex]\frac{1}{2}[/tex] hour

∵  [tex]\frac{1}{2}[/tex] hour =  

∴ Jeremy arrives to the factory in 30 minutes

∵ They leave their houses at the same time

Final answer:

Jason arrives at the factory first, taking approximately 25 minutes, while Jeremy arrives 5 minutes later, taking around 30 minutes to reach.

Explanation:

The question involves calculating time taken for different scenarios involving motion and relative speed. In the given scenario, Jason lives 25 miles away from the factory and drives at 60 miles per hour, while Jeremy lives 35 miles away and drives at 70 miles per hour. To find out who arrives at the factory first, we calculate the time each person takes to reach the factory.

For Jason: Time = Distance / Speed = 25 miles / 60 mph = 0.4167 hours.
For Jeremy: Time = Distance / Speed = 35 miles / 70 mph = 0.5 hours.
Clearly, Jason will arrive first.

The difference in arrival time between Jeremy and Jason is:
Jeremy's time - Jason's time = 0.5 hours - 0.4167 hours = 0.0833 hours, which is 5 minutes.

Jason arrives at the factory first, and Jeremy arrives 5 minutes later.

Answer:

  31 5/8 pounds

Step-by-step explanation:

The total weight is ...

  9(2 7/8 lb) + 2(2 7/8 lb) = (2 7/8 lb)(9 +1) = (23/8 lb)(11) = 253/8 lb

  = 31 5/8 lb

The total of package weights is 31 5/8 pounds.

Final answer:

The total weight of all ten packages that Jeff wants to mail is 31 5/8 pounds.

Explanation:

Jeff has ten packages to mail, with nine identical packages weighing 2 7/8 pounds each and one package weighing double the weight of one of the nine.

To find the total weight of all the packages, we first calculate the weight of the nine identical packages by multiplying their weight by the number of packages, which is:

2 7/8 pounds/package × 9 packages = 25 7/8 pounds

Next, we determine the weight of the tenth package:

2 × 2 7/8 pounds = 5 6/8 pounds, which simplifies to 5 3/4 pounds.

Finally, we add the total weight of the nine packages to the weight of the tenth package:

25 7/8 pounds + 5 3/4 pounds = 31 5/8 pounds.

Therefore, the total weight of all ten packages is 31 5/8 pounds.

Step-by-step explanation:

Use the equation speed = distance / time

To get distance you do speed X time

D =60t shows that

The distance traveled  = 60t.

Distance exists defined to be the magnitude or extent of displacement between two positions. Distance traveled exists the entire length of the path traveled between two positions. Distance traveled exists not a vector.

The independent variable exists as t (hours) and the dependent variable exists as d (distance). The total distance (d) depends on the number of hours (t). As the hours increase, the distance will rise. The distance relies on the amount of time traveling.

Speed = distance / time

Therefore, Distance = speed [tex]*[/tex] time

Distance = 60t
