A business bought 500 lamps for $10,000. They want to mark them up 25%. What is the retail price of each lamp?
zavuch27 [327]

Answer:

$25 a lamp

Step-by-step explanation:

First divide $10,000  by 500 lamps to find how much one of them cost

That is $20 a lamp so then multiply .25 *20 or 1/4 *20

you get 5 than add 20 +5=25

A ball is thrown vertically upward. After t seconds, its height h (in feet) is given by the function h(t)=92t-16t^2. What is the
nata0808 [166]

Answer:

132.25 feet

Step-by-step explanation:

Since the function is a quadratic representing height, and the coefficient of the t² is negative, the vertex of the parabola will be the maximum height achieved by the ball.  

The general form for a quadratic equation is ax² + bx + c,

here a is -16, and b is 92

To find the x coordinate of the vertex, use   x = -b/(2a)

We have x = -92/[2(-16)]

             

                     x = -92/-32

                         x= 23/8

Now plug that into the equation to find the y value, which will be the height...

y = 92(23/8) - 16(23/8)²

    y = 2116/8 - 16(529/64)

        y = 1058/4 - 529/4

              y = 529/4

                     y = 132.25

Given only the information in the diagram, determine if m is parallel to n . If so, name the postulate or theorem used to suppor
Helen [10]
From my research on the internet, the image attached supports this problem. The two lines are parallel, as supported by the converse of corresponding angles postulate. It states that:<span> If a </span>transversal<span> intersects two lines and the corresponding angles are </span>congruent<span>, then the lines are parallel.</span>
