Regina bought a handmade quilt at original cost $120 to sell in her quilt store. She marked the price up 55%.
Answer:
[tex]Selling\ price = \$190.65[/tex]
Step-by-step explanation:
Given
[tex]Price = \$123[/tex]
[tex]Marked\ up = 55\%[/tex]
Required
The selling price
This is calculated as:
[tex]Selling\ price = Price + Marked\ up* Price[/tex]
[tex]Selling\ price = \$123 + 55\% * \$123[/tex]
[tex]Selling\ price = \$123 + \$67.65[/tex]
[tex]Selling\ price = \$190.65[/tex]
Answer:
$66.00
Step-by-step explanation:
We are asked to find the amount of markup on Regina's quilt. The amount of markup is given by
markup rate×original price=amount of markup.
The markup rate is in decimal form.
Since the original price was $120, and the markup rate is 55%=0.55, we have
0.55×120=66.
Thus, the amount of markup on Regina's quilt was $66.00.

Answer:
45.18 mi
Step-by-step explanation:
What it is asking is to find the value of C.
Formula we're going to use:
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
C is the hypotenuse.
Replace with given values, so
[tex] {19}^{2} + {41}^{2} = {c}^{2} [/tex]
Rewrite so there is no squared
[tex]361 + 1681 = {c}^{2} [/tex]
Add the numbers
[tex]2042 = {c}^{2} [/tex]
Find the value of C by square rooting 2042
[tex] \sqrt{2042} = 45.1884941108[/tex]

What is the answer I need to know
Answer:
Arrange your numbers in numerical order.
Count how many numbers you have.
If you have an odd number, divide by 2 and round up to get the position of the median number.
If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.
the diameter of circle A is 8 inches. the diameter of circle B is 4 inches greater then the diameter of circle A. The diameter of circle C is 4 inches greater then the diameter of circle B
the area of circle A is ____ the area of circle B is ____ the area of circle C
Answer:
Step-by-step explanation:
radius of A = 4 in
area of A = 16π in²
radius of B = 6 in
area of B = 36π in²
radius of C = 8 in
area of C = 64π in²
Area of A is 16π/(36π) the area of B = 4/9 the area of B
Area of B is 36π/(64π) the area of C = 9/16 the area of B

What is the graph for if y is a function of x
Answer:
The y value of a point where a vertical line intersects a graph represents an output for that input x value. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output.

A six-sided number cube labeled 1 through 6 is rolled 600 times. An odd number is rolled 272 times. Compare the experimental probability of rolling an odd number with the relative frequency of rolling an odd number and select one of the statements below that best describes the situation. (5 points)
a
The experimental probability and relative frequency are the same.
b
The experimental probability is larger than the relative frequency.
c
The experiment probability is smaller than the relative frequency.
d
There is not enough information to determine the relative frequency.
Answer:
Relative frequency is defined as the number of "desired" results divided by the total number of possible results. Experimental probability is defined the same way. This means that the first choice is best, the experimental probability and relative frequency are the same.
The theoretical probability, on the other hand, would be 0.5, or 300/600, which is larger than the experimental probability.

When an amount of heat Q (in kcal) is added to a unit mass (kg) of a
substance, the temperature rises by an amount T (°C). The quantity dQ/dT, called
specific heat, is 0.18 (kcal/°C) for glass. If dQ/dt = 12.9 kcal/min for a 1 kg sample
of glass at 20.0 °C, find dT/dt for this same sample. (Note: T is for temperature, t is
for time.)
Answer:
The change in temperature per minute for the sample, dT/dt is 71.[tex]\overline {6}[/tex] °C/min
Step-by-step explanation:
The given parameters of the question are;
The specific heat capacity for glass, dQ/dT = 0.18 (kcal/°C)
The heat transfer rate for 1 kg of glass at 20.0 °C, dQ/dt = 12.9 kcal/min
Given that both dQ/dT and dQ/dt are known, we have;
[tex]\dfrac{dQ}{dT} = 0.18 \, (kcal/ ^{\circ} C)[/tex]
[tex]\dfrac{dQ}{dt} = 12.9 \, (kcal/ min)[/tex]
Therefore, we get;
[tex]\dfrac{\dfrac{dQ}{dt} }{\dfrac{dQ}{dT} } = {\dfrac{dQ}{dt} } \times \dfrac{dT}{dQ} = \dfrac{dT}{dt}[/tex]
[tex]\dfrac{dT}{dt} = \dfrac{\dfrac{dQ}{dt} }{\dfrac{dQ}{dT} } = \dfrac{12.9 \, kcal / min }{0.18 \, kcal/ ^{\circ} C } = 71.\overline 6 \, ^{\circ } C/min[/tex]
For the sample, we have the change in temperature per minute, dT/dt, presented as follows;
[tex]\dfrac{dT}{dt} = 71.\overline 6 \, ^{\circ } C/min[/tex]
