Step-by-step explanation:
4y=6
y=6/4
y-1=-14
y=-13
214+y=4
y=-210
8y=9
y=9/8
Find the value of X in this proportion.
- 27/4
- 18
- 9/8
- 9/2
Answer:
the answer is 9/2
Step-by-step explanation:
So you have (x+3)/6=5/4
Cross multiply and it will turn to this
4(x+3)=6×5 which is 30
= 4x+12=30
4x=30-12
4x=18
Divide both sides by 4 to make x subject of the formula
then your answer is 9/2

Step-by-step explanation:
-3r+9=-4r+5
-3r+4r=5-9
r=-4
Answer:
I got r=-1

Step-by-step explanation:
Which expression is equivalent to Syntax error from line 1 column 49 to line 1 column 73. Unexpected 'mathsize'.
Answer:
5x - 6
Step-by-step explanation:
(a) The probability that an automobile being filled with gasoline will also need an oil change is 0.35; the probability that it needs a new oil filter is 0.45, and the probability that both the oil and filter need changing is 0.25. (i) If the oil had to be changed, what is the probability that a new oil filter is needed? (ii) If a new oil filter is needed, what is the probability that the oil has to be changed? (b) 3 Cards are drawn in succession without replacement from an ordinary deck. Find the probability of the event A1 ∩ A2 ∩ A3, where A1 is the event that the first card is RED ace, A2 is the event that the second card Queen or King, and A3 is the event that the third card which is greater than 3 and less than Eight?
Answer:
0.714 ; 0.556 ; (A1 n A2 n A3) = 0
Step-by-step explanation:
Given that :
P(oil) = 0.35
P(filter) = 0.45
P(oil n filter) = 0.25
1)
P(filter | Oil) = P(oil n filter) / P(oil)
P(filter | Oil) = 0.25 / 0.35 = 0.714
11)
P(Oil | filter) = P(oil n filter) / P(filter)
P(Oil | filter ) = 0.25 / 0.45 = 0.556
Number of red aces = 2
Queen or king = 4 + 4 = 8
Number on card greater than 3 and less than 8 = {4,5,6,7} = 4 card ; for 4 suits = 4 * 4 = 16
Total number of cards in deck = 52
Choosing without replacement :
Hence,
A1 = 2 / 52
A2 = 8 / 51
A3 = 16 / 50
(A1 n A2 n A3) ;this means card common to all three events.
However, (A1 n A2 n A3) = 0 because ;
1.) No red ace card is greater than 3 and less than 8.
11.) An ace card can neither be a king nor a queen

Consider the arithmetic sequence:
10, 12, 14, 16, ...
If n is an integer, which of these functions generate the sequence?
Choose all answers that apply:
a(n) = 16 + 3n for n 2-2
A
b(n) = 14 + 2n for n > -1
c(n) = 10 + 3n for n > 0
Dd(n) = 8 + 2n for n > 1
Answer:
If n is an integer, the function that generate the sequence 10, 12, 14, 16, ... is [tex]\mathbf{d(n)=8+2n\:for\:n>1}[/tex]
Option D is correct option
Step-by-step explanation:
We are given the arithmetic sequence:
10, 12, 14, 16, ...
If n is an integer, which of these functions generate the sequence?
We need to find the nth term for the given sequence
The nth term for arithmetic sequence will be: [tex]a_n=a_1+(n-1)d[/tex]
where aₙ is nth term, a₁ is first term and d is common difference
Looking at the sequence a₁ = 10 and d = 2
So, nth term will be:
[tex]a_n=a_1+(n-1)d\\a_n=10+(n-1)2\\a_n=10+2n-2\\a_n=8+2n[/tex]
So, nth term is: [tex]a_n=8+2n[/tex]
In the options below, the only correct answer is option D. so, we can write nth term as: [tex]d(n) = 8 + 2n\: for\: n > 1[/tex]
So, If n is an integer, the function that generate the sequence 10, 12, 14, 16, ... is [tex]\mathbf{d(n)=8+2n\:for\:n>1}[/tex]
Option D is correct option
Answer:
D) 8 + 2n for n > 1

If a ball is thrown straight up into the air with an initial velocity of 85ft/s its height in feet after t seconds is given by y=85t - 16t^2. Find the average velocity for the time period beginning when t=1 and lasting 0.1, 0.01, 0.001
Answer:
[tex]51.4\ \text{m/s}[/tex]
[tex]52.84\ \text{m/s}[/tex]
[tex]52.984\ \text{m/s}[/tex]
Step-by-step explanation:
The function of displacement is
[tex]y=85t-16t^2[/tex]
[tex]\text{Average velocity}=\dfrac{\text{Total displacement}}{\text{Time elapsed}}[/tex]
Lasting 0.1 s
[tex]v_1=\dfrac{y(1.1)-y(1)}{1.1-1}\\\Rightarrow v_1=\dfrac{85\times 1.1-16\times 1.1^2-(85-16)}{0.1}\\\Rightarrow v_1=51.4\ \text{m/s}[/tex]
The average velocity is [tex]51.4\ \text{m/s}[/tex]
Lasting 0.01 s
[tex]v_2=\dfrac{y(1.01)-y(1)}{1.01-1}\\\Rightarrow v_2=\dfrac{85\times 1.01-16\times 1.01^2-(85-16)}{0.01}\\\Rightarrow v_2=52.84\ \text{m/s}[/tex]
The average velocity is [tex]52.84\ \text{m/s}[/tex]
Lasting 0.001 s
[tex]v_3=\dfrac{y(1.001)-y(1)}{1.001-1}\\\Rightarrow v_3=\dfrac{85\times 1.001-16\times 1.001^2-(85-16)}{0.001}\\\Rightarrow v_3=52.984\ \text{m/s}[/tex]
The average velocity is [tex]52.984\ \text{m/s}[/tex]

right triangle.
C. Knowing that 32 + 42 = 52, draw any two of the sides with a right
angle between them. The third side will fit to form a right triangle.
D. Knowing that 42 + 52 < 62, draw the 4-foot side and the 5-foot side

k-3k²-3k+2k²
what is the answer
please help me
Answer:
Assuming you want to simplify the expression, it can be shortened to:
-k² - 2k
Step-by-step explanation:
What you need to do here is called grouping like terms. Like terms can be described as terms that have the same factors. In this case, the factors we're looking at are k and k²:
Given:
k - 3k² -3k + 2k²
We'll rearrange to group like expressions:
= -3k² + 2k² + k -3k
Pull out common factors:
= (-3 + 2)k² + (1 - 3)k
And simplify:
= -k² - 2k
