Answer:
14
Step-by-step explanation:
The question is asking for the value of 4b -2 when b= 4. Thus, substitute b= 4 into the expression.
4b-2
When b= 4,
4b -2
= 4(4) -2
= 16 -2
= 14

You pick a card at random. Without putting the first card back, you pick a second card at random.What is the probability of picking a 7 and then picking a number less than 5?
Simplify your answer and write it as a fraction or whole number.
Answer:
[tex]Probability\ of\ picking\ a\ 7=\frac{1}{10}\\Probability\ of\ picking\ a\ card\ less\ than\ 5=\frac{4}{9}[/tex]
Step-by-step explanation:
[tex]We\ are\ given\ that,\\The\ total\ outcomes\ to\ the\ Random\ Experiment\ A\ are\ 1,2,3,4,5,6,7,8,9,10.\\ (We\ don't\ consider\ Ace\ Cards\ or\ Face\ Cards, here.)\\Hence,\\Lets\ consider\ picking\ the\ first\ Card:\\\\Here,\\The\ favorable\ condition\ is\ getting\ a\ 7.\\ No.\ of\ favorable\ elementary\ events=1\\ Total\ no.\ of\ elementary\ events=10\\ We\ know\ that,\\[/tex]
[tex]Probability[of\ an\ Event\ A]=\frac{Favourable\ no.\ of\ elementary\ events\ to\ A}{Total\ no.\ of\ elementary\ events}\\Probability[of\ picking\ a\ 7]=\frac{1}{10}[/tex]
[tex]Now,\\As\ we've\ already\ picked\ a\ card[i.e\ 7],\\The\ total\ outcomes\ to\ the\ Random\ Experiment\ A\ are\ 1,2,3,4,5,6,8,9,10.\\Hence,\\Lets\ consider\ picking\ another\ card\ less\ than\ 5:\\Here,\\The\ favorable\ condition\ is\ picking\ a\ card\ less\ than\ 5.\\Hence,\\The\ favorable\ outcomes\ are\ 1,2,3,4.\\No.\ of\ favorable\ elementary\ events=4\\Total\ no.\ of\ elementary\ events=9\\As\ we\ already\ know\ that,\\[/tex]
[tex]Probability[of\ an\ Event\ A]=\frac{Favourable\ no.\ of\ elementary\ events\ to\ A}{Total\ no.\ of\ elementary\ events}\\Probability[of\ picking\ a\ card\ less\ than\ 5]=\frac{4}{9}[/tex]
Can I get help plz ?!? Mark BRAINLIEST?
Answer:
2
Step-by-step explanation:
Perimeter of a rectangle = 2(length + breadth)
=> 2{2x + (x + 4)) = 20
=> (2x + x + 4) = 20/2 = 10
=> 3x + 4 = 10
=> 3x = 10 - 4 = 6
=> x = 6/3 = 2
Here, according to the diagram
Length = 2x = 2(2) = 4
Breadth = x + 4 = 2+4 = 6
But breadth should always be lesser than the length. From this, it can be concluded that the actual breadth is 2x and actual length is x + 4, for perimeter to be 20.
Answer:
X is 2 I am sure
Step-by-step explanation:
2+4=6
6+6=12
2*2=4
4+4=8
12+8= 20
HURRY I HAVE TO FINISH THIS HOMEWORK IN 10 MINS PLEASE HELP
Answer:
135°
Step-by-step explanation:
Answer:
135 in degree measure.
Step-by-step explanation:
the angle opposite to 35 becomes also 35 by the rule vertically opposite angle. Then The traingle has three points as 100 and 35. Similarly the remaining angle becomes 45 .then 45+ unknown angle is equal to 180 by linear pair law. hence it becomes 135.....
HOPE IT HELPS!!
Guys, Help me. In a 5th grade math problem, It says, “Find the Unknown Number”, And the problems are ?/2 x 8=4. ?x 5/6= 20/6, Or 3 and 1/3. And the last problem, 1/? X 18=3
I need answers under a day and...Just please help, I don’t know how to solve this.
When you're multiplying fractions by a whole number, flip the equation around. For the first one, ?/2x8=4 can be converted to 8/2=4. Or half of 8 is 4.
The next one is missing the whole number. It converts to 20/6 / 5/6, which is equal to 20/5 and 6/6, which is 4/1 or 4.
The last question can be converted to 18/3=?, which is 6. So the answer to that one is 1/6 x 18=3.
1. 1/2 x 8 = 4
2. 4 x 5/6 = 20/6
3. 1/6 x 18 = 3

If m = (3x-1) and n = (3x+1),sjow that x² = mn+1 by 9
Answer:
See proof below
Step-by-step explanation:
Given that m = (3x-1) and n = (3x+1)
Taking the product
mn = (3x-1)(3x+1)
mn = 9x^2+3x-3x-1
mn = 9x^2 - 1
mn+1 = (9x^2-1+1)
mn+1 = 9x^2
Dividing both sides by 9
(mn+1)/9 = (9x^2)/9
(mn+1)/9 = x^2
Swap
x^2 = (mn+1)/9
This shows the required proof

What is x? Complementary or Supplementary Angles?
Answer:
x = 17 degrees
Complementary Angle
Step-by-step explanation:
x is a complementary angle, this means that when you add it's angle with another angle, the sum would be 90 degrees
To figure out what x is, subtract 73 from 90:
90 - 73
which gives you 17
therefore, x = 17
This table shows how much each type of meat costs at a local deli.
Type of Meat Price per Pound
ham $5.99
turkey $4.99
roast beef $6.99
salami $2.99
bologna $3.99
A customer purchased 1/4 pound of ham, 1 1/2 pounds of turkey, 1 pound of
roast beef, and 3/4 pound of bologna. Approximately what will the customer pay
for the purchase before sales tax?
Answer:
5.99 • .25 = 1.50
4.99 • 1.5 = 7.48
6.99 • 1 = 6.99
3.99 • 0.75 = 2.99
The costumer will pay approximately $18.96 before taxes.

< PRS = 123°
<QOP = x
Now
< PRS + <QRP = 180° { Being linear pair }
123° + <QRP = 180°
<QRP = 180° - 123°
< QRP = 57°
< QOP = x
= 2 * < QRP < angle at the centre is twice the angle at the circumference >
= 2 * 57°
= 114°
Therefore x = 114°

Two lines that have the same y-intercept intersect at exactly one point.
Not always. There are some situations where 2 lines have the same y-intercept, but have infinite solutions. But, most of the time, yes.
---
sorry if this doesn't help
Answer:
always two line will intersect only once. if they have the same y intercepts then that is their point of intersection. these lines are perpendicular because their slopes are negative reciprocals of each other. as can be seen on the graph, their only point of intersection is at the y intercept.
The value of Desmond's home is modeled by the function V (x) = 275,000(1.09) ²/³x, where x is the number of years since 2012. By what approximate percentage rate is the value of Desmond's home increasing per year?
Answer:
6%Step-by-step explanation:
Given function
V(x) = 275000(1.09)^(2/3x)Every year the value is changing at the rate:
(1.09)^(2/3) = 1.059 ≈ 1.06The rate of 1.06 is equivalent of 6% increase per year

how do you factor quadratic expressions with coefficient and without c?
Answer:
Completing the square. I mean, you can, for some values of a and b, but it's not going to help much if it is messy. Nope!
Factoring. Yes. It's really easy since there is an obvious common factor.
Square root theorem. No idea what this is. And I don't know how it would help.
Quadratic equation. This works, but is a little long for what you have to do.\
