Answer:
[tex]-273.15^{\circ}\text{C}[/tex]
Step-by-step explanation:
[tex]T_i[/tex] = Initial temperature of sodium gas = [tex]-78.5^{\circ}\text{C}[/tex]
[tex]\Delta T[/tex] = Change in temperature of sodium gas = [tex]-194.65^{\circ}\text{C}[/tex]
[tex]T_f[/tex] = Final temperature of sodium gas
Change in temperature of gas is given by
[tex]\Delta T=T_f-T_i\\\Rightarrow T_f=\Delta T+T_i\\\Rightarrow T_f=-194.65+(-78.5)\\\Rightarrow \Delta T=-273.15^{\circ}\text{C}[/tex]
The new temperature of sodium gas is [tex]-273.15^{\circ}\text{C}[/tex].

Help please. Question is on the picture.
Answer:
Yes; P(blue glove) = 11/20 and P(not blue glove) = 9/20
The probability of selecting a blue glove is greater than the probability of not choosing a blue glove.
See the attached diagram below
==============================================
Explanation:
There are 3 red gloves, 6 black gloves, and 11 blue gloves. So there are 3+6+11 = 20 gloves total in the drawer. The probability of picking blue is 11/20. The probability of not picking blue is 9/20 since we had 3red+6black = 9 gloves that are not blue. Or you could note that 11/20 + 9/20 = 20/20 = 1.
------------------
The probability of picking blue is greater than the probability of not picking blue. Oliver is likely to pick a second blue glove.
The way to see how 11/20 is larger than 9/20 is to compare the numerators. We see that 11 > 9, so that helps show 11/20 > 9/20.
You could also use your calculator to look at the decimal form of each fraction
11/20 = 0.55
9/20 = 0.45
This shows 11/20 is larger.
A recipe for a loaf of bread calls for of a cup of flour. If Milo used 12 cups of flour, how many loaves of bread did he prepare?
Answer:
12 loaves of bread
Step-by-step explanation:
If making one loaf of bread takes one cup of flour, using 12 cups you would make 12 loaves.
Answer:
18
Step-by-step explanation:
1 loaf bread calls for 2/3 of a cup of flour
he used 12 cups
12 ÷ 2/3 = 12 × 3/2 = 6×3 = 18

9514 1404 393
Answer:
nonoStep-by-step explanation:
If the graph is not a straight line, it is not a linear function. Neither graph 1 nor graph 2 is a straight line, so neither is a linear function.
__
Graph 2 is made of parts of two straight lines. It is not one straight line, so not a linear function. It is called "piecewise linear," which is different.

3k-2=10 whats the answer
Answer:
k = 4
Step-by-step explanation:
3k - 2 = 10
3k - 2 + 2 = 10 + 2 (adding 2 to both sides)
3k = 12
3k/3 = 12/3 (dividing both sides by 3)
k = 4

20 feet of lumber cost $138.40. what is the cost per foot
Answer: $6.92
Step-by-step explanation: Whenever you see the word per in a math problem, that means division. So right now, you could set up an equation that looks like this. 20L=130.40 (let L mean cost per foot of lumber). If you want to find the cost per foot you need have 1L or just L on one side of the equation. Well, the easiest way to do that would be to divide by 20 on both sides. And that would get you L= 6.92. And since L means the cost per foot of lumber, that cost would be $6.92. Hope this helps!

Put the exponent aside and simplfy the base by pulling out like factors :

Remember the 4th law of exponents : (a • b)m= am• bm

Put the exponent aside, try to factor xy3z+1
Theory : A sum of two perfect cubes, a3 + b3 can be factored into :

Proof : (a+b) • (a2-ab+b2) =
a3-a2b+ab2+ba2-b2a+b3 =
a3+(a2b-ba2)+(ab2-b2a)+b3=
a3+0+0+b3=
a3+b3
Check : 1 is the cube of 1
Check : x 1 is not a cube !!
Ruling : Binomial can not be factored as the difference of two perfect cubes
Dividing exponents:
4.3 23 divided by 22 = 2(3 - 2) = 21 = 2

How many yards are in 96 inches by 30 feet?
Answer:30 x 96 feet = 10 x 32 yards
Step-by-step explanation:Convert 30 x 96 feet to yards
To convert length x width dimensions from feet to yards we should multiply each amount by the conversion factor. One foot equals 0.333333 yards, in order to convert 30 x 96 feet to yards we have to multiply each amount of feet by 0.333333 to obtain the length and width in yards. In this case to convert 30 x 96 feet into yards we should multiply the length which is 30 by 0.333333 and the width which is 96 by 0.333333. The result is the following:
30 x 96 feet = 10 x 32 yards
Definition of foot
A foot (symbol: ft) is a unit of length. It is equal to 0.3048 m, and used in the imperial system of units and United States customary units. The unit of foot derived from the human foot. It is subdivided into 12 inches.
Definition of yard
A yard (symbol: yd) is a basic unit of length which is commonly used in United States customary units, Imperial units and the former English units. It is equal to 3 feet or 36 inches, defined as 91.44 centimeters.
Meters to yards formula and conversion factor
To calculate a foot value to the corresponding value in yards, just multiply the quantity in feet by 0.333333 (the conversion factor).
Meters to yards formulae
yards = feet * 0.333333
The factor 0.333333 is the result from the division 1 / 3 (yard definition). Therefore, another way would be:
yards = feet / 3
Using our feet to yards converter you can get answers to questions like:
- How many yards are in 30 x 96 feet?
- 30 x 96 feet is equal to how many yards?
- How to convert 30 x 96 feet to yards?
- What is 30 x 96 feet in yards?

y=-1/2x+4
one solution: (8, 0)
one solution: (0, 8)
no solution
infinite number of solutions
Answer:
The system of equations has no solution.
NO SOLUTION!
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}y=-\frac{1}{2}x+4\\ x+2y=-8\end{bmatrix}[/tex]
Arrange equation variables for elimination
[tex]\begin{bmatrix}y+\frac{1}{2}x=4\\ 2y+x=-8\end{bmatrix}[/tex]
[tex]\mathrm{Multiply\:}y+\frac{1}{2}x=4\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:2y+x=8[/tex]
[tex]\begin{bmatrix}2y+x=8\\ 2y+x=-8\end{bmatrix}[/tex]
subtracting equation 2y+x=8 from 2y+x = -8
[tex]2y+x=-8[/tex]
[tex]-[/tex]
[tex]\underline{2y+x=8}[/tex]
[tex]0=-16[/tex]
so the equations become
[tex]\begin{bmatrix}2y+x=8\\ 0=-16\end{bmatrix}[/tex]
0 = -16 is false, therefore the system of equations has no solution.
NO SOLUTION!

A shirt marked $320.00 was sold at a discount of 5%. What was the selling price?
Answer:
304
Step by step:
Using your calculator 5% of 320 is 16.
Since it was a discount, you subtract 16 since you're marking it down.
320-16=304
304 is your answer
How do I know? Well, there it takes 20+20+20+20+20 to equal a hundred. We can do this same math for this problem. 16 x 20 is 320
Answer:
$304.00
that is really freaking expensive shirt lol.
i thought you said shlt, not shirt lol
anyway...
Step-by-step explanation:
320 times 0.05
(don't make the mistake of 0.5 that is 50%, not 5%. )
320*0.05= 16
subtract it
320-16= 304
The class has 12 girls and 16 boys. What is the ratio of total students to boys in simplest form?
Answer:
7:4
Step-by-step explanation:
total students = 28
so ratio 28:16
which will be reduced to14:8
then 7:4
boys : girls
= 16 : 12
= 16/12
[After simplifying]
= 4/3
So, ratio of boys to girls in simplest form => 4 : 3

Jasmine created a scale drawing of her room. She used a scale of 1 in:3 feet. The drawing is 8 inches long by 6 inches wide. What is the area of the room in square feet?
Answer:
The area of the room is 432 square feet
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ The scale drawing of the room is 1 inch: 3 feet
→ That means each 1 inch in the drawing represents 3 feet in real
∵ The drawing is 8 inches long by 6 inches wide
∴ The drawing length of the room = 8 inches
∴ The drawing width of the room = 6 inches
→ By using the ratio method
→ inches : feet
→ 1 : 3
→ 8 : L
→ 6 : W
→ By using the cross multiplication
∵ 1 × L = 8 × 3
∴ L = 24
∴ The actual length of the room is 24 feet
∵ 1 × W = 6 × 3
∴ W = 18
∴ The actual width of the room is 18 feet
Use the formula of the area of the rectangle to find the area of the room
∵ Area of rectangle = length × width
∴ Area of the room = 24 × 18
∴ Area of the room = 432 feet²
∴ The area of the room is 432 square feet
