In this question, we have two unit that needed to be converted, meter/second into kilometer/minute.
First, we need to convert meter into the kilometer. One kilometer is equal to 1000 meter. To change meter into the kilometer, the unit used for multiplication should be km/1000m which is option C.
Then we need to convert second into the minute. One minute is equal to 60 seconds. To change "/second" into "/minute" the multiplication unit should be 60second/ 1 minute which was option A

Write an equation in point-slope form for the line through the given point with the given slope Point: (3, -4) Slope = 6

Answers

Answer: y + 4 = 6(x - 3)

Step-by-step explanation:

The point-slope formula is y - [tex]y_1[/tex] = m(x - [tex]x_1[/tex]) where m is the slope and ( [tex]x_1[/tex], [tex]y_1[/tex]) is a point on the graph.

Using the formula given above, we will plug in what we know to write our equation.

y - [tex]y_1[/tex] = m(x - [tex]x_1[/tex])

y - (-4) = (6)(x - (3))

y + 4 = 6(x - 3)

48 inches long and 24 inches wide. What is the area of the poster in square feet?

Answers

Hi there! We just need to use some simple multiplication for this equation. I'll walk you through it.

Remember that 1 foot is 12 inches. This'll come in handy later.

48 * 24 = 1152

Now, divide this by 12.

1152/12 = 96

There you go! The area of the poster is 96 square feet.

:)

the area of the poster in square feet is, 8 feet²

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Length of poster = 48 inch

Width of poster = 24 inch

Since, We know that;

1 feet = 1 / 12 inch

Hence, Length of poster = 48 / 12

= 4 feet

And, Width = 24 / 12

= 2 feet

Thus, Area of poster = Length x Width

= 4 x 2

= 8 feet²

Step-by-step explanation:

alright lets get started.

The side of cube is given by the function

[tex]s(v)=\sqrt[3]{v}[/tex]

If, Jason wants to build a cube with the minimum volume 64 cubic centimeters.

Plugging the value of volume in above function

Classify each pair of numbered angles.

Drag and drop the descriptions into the boxes to correctly classify each pair of numbered angles. Each description may be used more than once.

Adjacent

Linear Pair

Vertical

None

Answers

Adjacent angles are angles with a common side and vertex, linear pairs are adjacent angles that are supplementary, and vertical angles are angles made by the same two lines but on opposite sides.

For the first one, 5 and 6 clearly do not share a side but they are made up by the same 2 lines and are opposite of each other, making them vertical.

For the next one, since the angles only share 1 line (and not a side) they can't be any of the above.

The paired numbered angles can be classified as follows:

<5 and <6 are vertical angles

<1 and <2 are none (not vertical, not adjacent, not a linear pair)

Recall the following:

Adjacent angles share a corner and a common side, but do not overlap.Linear pairs are two angles that are adjacent to each other along a straight line.Vertical angles share a common vertex but are not adjacent to each other.

Therefore, from the above stated facts, we can conclude that:

<5 and <6 are vertical angles

<1 and <2 are none (not vertical, not adjacent, not a linear pair)

Given data:

To find the value of a when given π/7 = a/4, cross-multiplication is done and a is solved as:

When two fractions are equal, to eliminate the denominators, the cross multiplication is executed and the unknown variable is solved.

Cross-multiplying the equation:

π * 4 = 7 * a

Simplifying the equation:

4π = 7a

To solve for a, divide both sides of the equation by 7:

a = (4π) / 7

Triangle JKL is isosceles. The measure of angle J is 72° and the measure of angle K is 36°. Which statement describes angle L?

Answers

This can have two scenarios: Angle J is the vertex and angle K is one of the base angles, or angle K is the vertex and angle J is one of the base angles. We can check this easily by seeing if they add up to 180.

Checking if the base angle is 72, we see that it fits, because 36+2(72)=180. Thus, the two base angles are angles J and L. Angle L is 72°.

Hope this helped!

b.) Angle L is a base angle and measures 72°.
