Answer:
Hello!!!
In this specific case the constant of proportionality is s (speed).
Step-by-step explanation:
The constant of proportionality stay "constant" (as the name suggests) in a certain case.
meaning, the speed itself remains constant at any given distance or time.
You can use the constant of proportionality and either distance or time to find the missing varliable since it remains constant.
you can also switch up the formula:
d=st
t=d/s
s=d/t
i really hope this helps!!!!!
A ream of A4 paper contain 500 sheets the size of each paper is 297mm long and 210mm wide the volume of the ream is 3742.2cm find the thickness of each sheet of paper answer in millimeters
The thickness of each sheet of paper is 0.0012mm.
To find the thickness of each sheet of paper answer in millimeters.
What is mensuration?The act of measuring geometry applied to the computation of lengths, areas, or volumes from given dimensions or angles.
Given that:
A ream of A4 paper contain 500 sheets the size of each paper is 297mm long and 210mm wide the volume of the ream is 3742.2cm.
To convert cm in mm.
3742.2cm=37422 mm
Surface 1 sheet:
(297mm) X 210mm) =
62370[tex]mm^{2}[/tex]
Volume 1 sheet:
37422mm : 500 =
74.844mm
Thickness of 1 sheet:
74.844mm : 62370mm =
0.0012mm
So, the thickness of each sheet of paper is 0.0012mm.

Answer:
2) 10.01 year
Step-by-step explanation:
1) already answered elsewhere in your posts
2) 9000 = 6500 e^(.0325 * t) where t = years
9000/6500 = e^(.0325*t) take ln (natural log) of both sides
.3254224 = .0325t
t = 10.01 10.01 year
If f(1)=1f(1)=1 and f(n)=f(n-1)^(2)-1f(n)=f(n-1)
2
-1 then find the value of f(4)f(4).
Answer:
f(4) = 0
Step-by-step explanation:
For many sequences that involve recursive formulas, the quickest way to find the value of a given term is to evaluate those leading up to it. That seems to be the case here.
givenf(1) = 1f(n) = f(n -1)² -1findf(4)solutionThe next term after the one given is ...
f(2) = f(1)² -1 = 1² -1 = 0
Then we have ...
f(3) = f(2)² -1 = 0² -1 = -1
f(4) = f(3)² -1 = (-1)² -1 = 0
The value of f(4) is 0.

Additional comment
Now that we have seen a few terms of the sequence, we can write an explicit formula for the terms after the first:
f(n) = (-1 +(-1)^n)/2 . . . integer n ≥ 2

Step-by-step explanation:
if one angle of a triangle is 63 and the other two are 7x degrees and 6x degrees what is X worth
Answer:
x = 9
Step-by-step explanation:
Sum of all angles of a triangle = 180
63 + 7x + 6x = 180
63 + 13x =180
13x = 180 - 63
13x = 117
x = 117/13
x = 9
Answer:
X= 9
Step-by-step explanation:
The angles in a triangle all add up to 180°
Hence we can form this equation :
63 + 7x + 6x = 180°
Subtracting 63 from both sides:
7x + 6x = 117°
Adding together to find the total X:
13x = 117°
Finally, diving by 13 on both sides:
X = 9

The first answer is correct
Step-by-step explanation:
< O Z Q = < O Z P + < Q Z P
Given that,
< O Z Q = 12x - 4
< O Z P = 6x + 4
< Q Z P = 3x + 10
Let us solve it now.
< O Z Q = < O Z P + < Q Z P
12x - 4 = 6x + 4 + 3x + 10
Combine like terms and make the x as the subject.
12x - 4 = 9x + 14
12x - 9x - 4 = 14
3x - 4 = 14
3x = 14 + 4
3x = 18
Divide both sides by 3.
x = 6

GR. 9 QUESTION 1/ VRAAG 1: Simplify the following: / Vereenvoudig die volgende: 1.1 -8xy-6xz + 10xy + 9xz - 4yx
1.2 m² - 4m - 1 + m² - 8m + 5-6m² +3m - 1
Answer:
Below in bold.
Step-by-step explanation:
-8xy-6xz + 10xy + 9xz - 4yx (Note 4yx = 4xy)
Bringing like terms together we have:
-8xy + 10xy - 4xy - 6xz + 9xz
= -2xy + 3xz.
m² - 4m - 1 + m² - 8m + 5-6m² +3m - 1
= m² + m² - 6m² - 4m - 8m + 3m - 1 + 5 - 1
= -4m² - 9m + 3.
