A music store originally purchased a piano at a cost of $892.03 and marked it up 125%. After a few weeks, however, the store discounted the piano 50% in order to make room for new merchandise. What was the discounted price?

Answers

Answer:

$557.52

Step-by-step explanation:

1. Find the marked up price.

125% = 1.25

$892.03 x 1.25 = $1,115.04

2. Find the discounted price.

50% = 0.5

$1,115.04 x 0.5 = $557.52

t midnight, a candle was lit. At 15 minutes past midnight, the candle was 4 inches tall, and you notice that it burns at a rate of 0.75 inches per hour.
(a)Write the point–slope form of the function that gives the height of the candle, h, in inches, as a function of time, t, in minutes past midnight, as the candle burns.
(b)When is the candle 1 inch tall?

Answers

Answer:

a)   t-4 = 3 (i - 1/4h) =  h = 3i - 3 3/4h  

= t = -0.75

= h = 4  

b) 3.30am = 1 inch.

Step-by-step explanation:

a)   formula for point slope form = y - y1 = m(x-x1)

a) t-4 = 3(i - 1/4h)  converts to  t-4   = 3i - 3/4h  = t = 3i- 3 3/4

x = - 0.75 y = 4  =     t= -0.75 and h = 4

b) 12.15am = 4 inches

1.15am = 3.25 inches

2.15am = 2.5 inches

3.15am = 1.75inches

3.30 = 1 inches

3.15 + 15mins = 1 inch

Answer:

42.5 square units

Step-by-step explanation:

To solve, we can split this shape up into 4 known shapes:

2 unit by 2 unit triangle

2 unit by 2 unit square

2 unit by 5 unit triangle

3.5 unit by 9.0 unit rectangle

Now let's solve these areas:

2 x 2 = 4 / 2 = 2

2 x 2 = 4

2 x 5 = 10 / 2 = 5

3.5 x 9.0 = 31.5

Then add all these values together:

2 + 4 + 5 + 31.5 = 42.5

Evaluate:

Basically replace the letters in the equation with their corresponding numbers and then solve the equation like normal. (Replace b with 5, since b=5) (replace x with 3, since c=3)

how many cubes with side length of 1/3cm does it take to fill the prism l=2 w=4/3 h=2

Answers

Given :-

Dimensions of cube = 1/3 cm *1/3cm *1/3cm.Dimensions of cuboidal prism = 2cm*4/3cm *2cm .

To Find :-

The number of cubes that can be filled.

Answer :-

The number of cubes will be say ' n ' ,

n = Volume of cuboid / Volume of cube n = 2cm*4/3cm *2cm ÷ 1/3 cm *1/3cm *1/3cmn = 2² * 4 * 3³ / 3 n = 16 * 9n = 144

Hence the number of cubes is 144.

Point Fis on line segment EG. EG = 100, EF = 4x - 20, and FG = 2x + 30. Write an equation that you would use to solve for x, then state the value of x, and the length
of line segments EF and FG.

Answers

Step-by-step explanation:

Line segment = EG

point on a line segment = F

EG = 100

EF = 4x - 20

FG = 2x + 30

a/q, EF + FG = EG

the equation is

4x - 20 + 2x + 30 = 100

now solution for x is

4x - 20 + 2x + 30 = 100

6x + 10 = 100

6x = 100 - 10 = 90

x = 90/6 = 15

therefore, value of x is 15.

and according to given information

EF = 4x - 20 = 4(15) - 20 = 60 - 20 = 40

FG = 2x + 30 = 2(15) + 30 = 30 + 30 = 60

Write an equation in slope intercept form for the line perpendicular to y = 2x - 3 that passes through the point (-3, -3)

Answers

Answer:

y=-1/2x-9/2

Step-by-step explanation:

check picture

The equation of the line perpendicular to y = 2x - 3 that passes through the point (-3, -3) is y = (-1/2)x - 9/2 in slope-intercept form.

To find the equation of a line perpendicular to y = 2x - 3, we need to determine the slope of the original line and then find the negative reciprocal of that slope.

The original line has a slope of 2. The negative reciprocal of 2 is -1/2.

Now, we have the slope (-1/2) and the point (-3, -3) that the perpendicular line passes through.

We can use the point-slope form of a linear equation to write the equation of the line:

y - y1 = m(x - x1)

Substituting the values:

y - (-3) = (-1/2)(x - (-3))

y + 3 = (-1/2)(x + 3)

Expanding and simplifying:

y + 3 = (-1/2)x - 3/2

y = (-1/2)x - 3/2 - 3

y = (-1/2)x - 3/2 - 6/2

y = (-1/2)x - 9/2

Therefore, the equation of the line perpendicular to y = 2x - 3 that passes through the point (-3, -3) is y = (-1/2)x - 9/2 in slope-intercept form.

Answers

( - 6, 1.5 )

Step-by-step explanation:

( x1, y1 ) = ( - 2, - 1 )

Here,

x1 = - 2

y1 = - 1

( x2, y2 ) = ( - 10, 4 )

Here,

x2 = - 10

y2 = 4

Formula : -

Mid - point = ( x1 + x2 ) / 2, ( y1 + y2 ) / 2

Mid - point = ( - 2 - 10 ) / 2, ( - 1 + 4 ) / 2

Answer:

y= 5x+20

Step-by-step explanation:

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

The slope is 5 and a point on the line is (-4,0)

Substituting this information into the equation, we can solve for b

0 = 5(-4) +b

0 = -20+b

0+20 = -20+20+b

20 = b
