PLEASE ANSWER QUICK!!! The volume of ammonia in a balloon is now 6.1 L after changing the temperature from 52 °C to 79 °C. What was the original volume?
Answer:
the original volume is 4.0L
Step-by-step explanation:
Step one:
given data
V1= ?
T1= 52 °C
V2= 6.1L
T2= 79° C
Step two
applying the volume temperature relationship, which is
V1/T1= V2/T2
substituting we have
V1/52= 6.1/79
cross multiply we have
52*6.1= V1*79
317.2= 79V1
divide both sides by 79
V1= 317.2/79
V1=4.0L

Question is in picture
Answer:
[tex] \frac{y - 3}{x - 0} = \frac{3 - 1}{0 - 1} = \frac{2}{ - 1} \\ \frac{y - 3}{x} = - 2 \\ y - 3 = - 2x\\ 2x + y - 3 = 0 \\y = - 2x + 3 \\ \boxed{f(x) = - 2x + 3}[/tex]
B. is the right answer.hope this helps.
Bring 8/(a-x) to a denominator of x-a
Answer:
[tex]-\frac{8}{x-a}[/tex]
Step-by-step explanation:
[tex]\frac{8}{a-x}[/tex]
we can take common factor of -1 in the denominator
[tex]\frac{8}{-(-a+x)}=\frac{8}{-(x-a)}[/tex]
and now multiply and divide by -1
[tex]\frac{8}{-(x-a)}\cdot \frac{-1}{-1}=\frac{-8}{x-a}=-\frac{8}{x-a}[/tex]

Solve: a + 4 = 48
a = 43
a = 51
a = 44
a = 52
Answer:
a = 44 is correct
Step-by-step explanation:
a + 4 = 48
plug in the #'s 1 at a time
43 + 4 = 48
47 = 48 FALSE
51 + 4 = 48
55 = 48 FALSE
44 + 4 = 48 TRUE
52 + 4 = 48 FALSE
Hope this Helps!!!
Answer:
Your answer would be a= 44
Step-by-step explanation:
44+4=48
To check: 48-4=44
Therefore, your answer is 44
what is the ratio 5/7 to 2/7
Answer: What is the ratio of 7 to 2?
Students learn that a ratio is a comparison of two numbers or quantities. For example, if there are 2 shaded parts of a picture and 7 unshaded parts, the ratio of shaded parts to unshaded parts is 2 to 7. Note that the ratio 2 to 7 can also be written as 2:7 or 2/7
What is the ratio of 7 to 5?
20 : 28
5 : 7 = 20 : 28. And 7 is a fourth of 28.

7. Triangles CDE and RST are similar triangles. What is
the length of side CD in triangle CDE?
R
40 ft.
32 ft.
20 ft.
T
S
Answer:
CD = 25 ft
Step-by-step explanation:
[tex] \triangle CDE \sim \triangle RST[/tex]
[tex]\therefore \frac{CD}{20}=\frac{40}{32}[/tex]
(Corresponding sides of similar triangles are in proportion)
[tex]\therefore \frac{CD}{20}=\frac{5}{4}[/tex]
[tex]\therefore CD = \frac{5}{\cancel 4}\times \cancel {20} \:\:\blue{\bold{5}} [/tex]
[tex]\therefore CD = 5\times 5[/tex]
[tex]\therefore CD = 25\: ft[/tex]
Answer:
CD = 25 ft
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{CD}{RS}[/tex] = [tex]\frac{CE}{RT}[/tex] , substitute values
[tex]\frac{CD}{20}[/tex] = [tex]\frac{40}{32}[/tex] ( cross- multiply )
32CD = 800 ( divide both sides by 32 )
CD = 25
A bookstore charges a standard rate for paperback or hardback books. The cost of a paperback book is 4 dollars less than the cost of a hardback book. Recently, one day of sales totaled $1065.10. That day the bookstore sold 51 paperback books and 47 hardback books. Write a system representing this situation. Use the graph to estimate the solution of the system. What does the solution mean in this situation? How much does each type of book cost? Use substitution to verify your solution.
Answer: for one hard cover book it is about $17 and paperback is $13

John's bank account had $1,320 at the end of November. In December, he bought $645 worth of
groceries and spent $225 on his mom's birthday present. Luckily, he earned $350 mowing lawns and $50
for good grades. How much money does John have at the end of December?
Answer:
850 but im not sure lol
Step-by-step explanation:
645 + 225 = 870
1,320 - 870 = 450
450 + 350 = 800
800 + 50 = 850
