The freezing point of helium is 0.95 Kelvin. What is this temperature in degrees Fahrenheit?
Answer:
-457.96
Step-by-step explanation:
Step-by-step explanation:
273.15 + °C = K
°C = K - 273.15
0.95K to °C = 0.95 - 273.15 = -272.2°C
°C to °F
(9/5 °C) + 32 = °F
(9/5 × -272.2) + 32 = °F
-489.96 + 32 = °F
= -457.96°F

If a circle with a diameter of 4 inches rotates 1000°, what distance will any one spot on
its edge actually travel?
We first convert from degrees to radians multiplying by π/180:
θ = 1000° × π/180 = 17.45 rad
The radius is:
r = d/2 = 4 in /2 = 2 inch
So, The distance traveled is given by the product of the angle in radians and the radius. This is:
d = θr = (17.45 rad)(2 inch) = 34.9 inch
the ratio of 70 to 210
If you're looking for the lowest ratio for 70 to 210, it should be
1:3
70min=70×60=4200sec
ratio=4200/210
=210×20/210
=20/1
=20:1

If you want the roots they are 11/5 and 7 both positive.
what is the slope of a line with endpoints (-11,5) and (5,-7)
Answer:
-6/8
Step-by-step explanation:
Slope=y1-y2/x1-x2
Where (X1,y1) is (-11,5) and (X2,y2) is(5,-7)
Slope=5+7/-11-5
=-12/16
= -6/8
So the slope is -6/8
YW is the perpendicular bisector of ZT.
If TW = 3, YW = 8, and XZ = 12. Find XY.
Answer:
XY = 17 UNIT
Step-by-step explanation:
Given:
TW = 3
YW = 8
XZ = 12
Find:
XY
Computation:
TW = ZW = 3
So,
XW = 12 + 3
XW = 15
So
XY = √XW²+YW²
XY = √15²+8²
XY = √289
XY = 17 UNIT
Applying the definition of perpendicular bisector and the Pythagorean Theorem, the value of XY is calculated as: 17 units.
Recall:
A perpendicular bisector of a line divides a line segment into two equal halves.Also, it forms two opposite right angles on the point of bisection.Considering the diagram attached below, we are given that:
[tex]TW = 3\\\\YW = 8\\\\XZ = 12[/tex]
We need to find the length of XY.Applying the Pythagorean theorem:
[tex]XY = \sqrt{XW^2 + YW^2}[/tex]
XW = XZ + WZ
XZ = 12 (given)
WZ = TW = 3 (congruent segments)
Thus:XW = 12 + 3
XW = 15
Plug in the values of XW and YW into [tex]XY = \sqrt{XW^2 + YW^2}[/tex]
Thus:[tex]XY = \sqrt{15^2 + 8^2}\\\\\mathbf{XY = 17}[/tex]

If we estimate that 10 people can fit in a 5ft by 5ft area, then what would be your estimate of how many people can fit on a basketball court measuring 94ft by 50ft?
Answer:
1,880 people will fit in 94 ft by 50 ft
Step-by-step explanation:
We can estimate this using the area
For 5 ft by 5ft ; 10 people can fit in an area of 5 * 5 = 25 ft^2
In an area of 94 ft by 50 ft, the number of people that can fit will be;
let’s start with the area
Area = 94 * 50 = 4,700 square feet
10 people will fit in 25 square feet
x people in 4,700 square feet
25 * x = 10 * 4700
25x = 47,000
x = 47000/25
x = 1,880 people
Your subtotal at the store was $58.89. You have a 30% off coupon. If the sales tax rate is 5.5%, what is the total price for your shopping trip?
Answer:
$43.48
Step-by-step explanation:
58.89x.30=17.68
58.89-17.68=41.21
41.21x.055=2.27
41.21+2.27= $43.48
Answer:
$43.49
Step-by-step explanation:
When you take of 30%, multiply by 0.7
When you add 5.5%, multiply by 1.055
Start with $58.89
Take off 30%: 0.7 * $58.89 = $41.22
Add 5.5%: 1.055 * $41.22 = $43.49

Question 3 40 pts
An object is attached to a spring that is stretched and released. The equation d = a (cos(bt)) models the distance, d, of the object in inches above or below the rest position as a function of time, t, in seconds. If a = 5 and b = 5 Approximately when will the object be 2 inches above the rest position? Round to the nearest hundredth, if necessary.
Answer:
The object will be 2 inches above the rest position when at approximately 0.23 seconds
Step-by-step explanation:
The given parameters are;
The equation that models the distance, d, of the object in inches above or below the rest position = a×(cos(b·t))
If a = 5 and b = 5, we have;
d = 5 × (cos(5 × t))
When the object is approximately 2 inches above the ground, we have;
d = 2 = 5 × (cos(5 × t))
cos(5 × t) = 2/5
5 × t = cos⁻¹(2/5) ≈ 1.16
t = (cos⁻¹(2/5))/5 ≈ 1.16/5
t ≈ 0.23 s
The object will be 2 inches above the rest position when t ≈ 0.23 s.

(x - 18)^2 = 1
Answer:
x=17 or x=19
Step-by-step explanation:
(x−18)^2=1
First, simplify both sides of the equation.
x*2−36x+324=1
Then subtract 1 from both sides.
x^2−36x+324−1=1−1
x^2−36x+323=0
Factor left side of equation.
(x−17)(x−19)=0
Then set factors equal to 0.
x−17=0 or x−19=0
x=17 or x=19
Answer:
Its either x=17 or x=19

I need to know how to graph and use a table to solve for y=3x+0
Answer:
Step-by-step explanation:
On a table, you'd have two columns: one for your input(x) and one for your output(y). If given an x value, put it into the equation to solve for y, and if you have a y value, put it into the equation for x. You can also come up with your own x values and put them into the equation if you need to create a table from scratch I'm not sure what you're asking but this will help you fill in a table. Here's and example for this equation.
X Y
1 3
2 6
3 9
Graphs are pretty simple. Just find a value on the x-axis (horizontal), find the point on the line above or below this value, and look at what number it is for the y value. You can do this backwards if you need to find y when given x.

Find angle YWX using the perpendicular or angle bisector method.
Answer:
x = 5
Step-by-step explanation:
9x - 28 = 5x - 8 (because Y and X are equal, and XZ and YZ are equal)
add 8 to both sides
9x - 20 = 5x
subtract 9x from both sides
-20 = -4x
divide 4x from both sides
5 = x
x = 5

David is buying a television that is regularly priced at $450.The television is on sale for 20% off. Sales tax is 7%.Whicj expression will calculate the final price of the television.
Answer:
The final price of the television is $502.20.
Step-by-step explanation:
The information provided is:
CP = $450
d% = 20%
s% = 7%
Compute the final price of the television as follows:
[tex]SP=CP\times (1 + s\%)\times (1-d\%)[/tex]
[tex]=450\times (1+0.20)\times (1-0.07)\\\\=502.2[/tex]
Thus, the final price of the television is $502.20.
