A 12 volt battery is connected to two resistors in series. The first resistor has a resitance value of 5 Ohms and the current through the circuit is 1.5 Amps. What is the value of the second resistor?
a
9 Ohms
b
1.5 Ohms
c
5 Ohms
d
3 Ohms
Answer:
3 Ohms
Step-by-step explanation:
U1 = 5 ohm × 1.5 amps = 7.5 V
U2 = U - U1 = 12 - 7.5 = 4.5 V
R2 = U2 / I = 4.5 / 1.5 = 3 Ohms
If < ABC forms a linear pair with < CBD, use the linear pair postulate to determine the value of X. Then find the measure of each angle.
X = _____ ??
m < ABC _____ ??
m < CBD _____ ??
Please help! I’ll give brainliest!!
Step-by-step explanation:
2x+13x-15=180 since a linear pair is a pair of consecutive angles that adds up to 180 degrees.
15x-15=180 because we combine like terms.
15x=165 because of the subtraction property of equality.
x=11 by the division property of equality.
abc=22 by substitution and multiplication
cbd=143-15 by substitution and multiplication
cde=128 by subtraction

If the graph of y=|x| is compressed vertically by a factor of 1/3, reflected about the x-axis and translated 3 unit(s) left and 5 unit(s) up, what is the equation of the new graph?
Answer:
Y= -1/3 |x+3| +5
Step-by-step explanation:
An absolute value will always make a V line.
In your particular problem it wants you to reflect it over the x axis, and to do this you simply need to place a negative.
A negative in the beginning of the problem is only there to say whether you flip your line or not, and this means you don't have to worry about it any more.
What it looks like so far: Y= -
Next it wants you to compress the line vertically by 1/3
A number that causes your line to compress is always less than one
A number that stretches your line would be 1 or more
This number is always placed right next to the left of the parenthesis or absolute value.
What it looks like so far: Y= - 1/3
Now we want the line to move left 3 units.
We are now inside of the absolute value because this is where we move the line left or right. This can get a little confusing, but once you get it then you don't forget it.
Inside the line.. a -# moves right and a +# moves left.
This number should be placed inside the absolute value and to the right of the x.
What it should look like: Y= - 1/3 |x + 3|
Now they want us to move the line up by 5 points.
To the outer right side of the absolute value is where we move things up or down.
To move a number up you need to place a + sign with however many places it wants you to move to the right of the sign, but to move the line down you need to place a - sign with however many places it wants you to move to the right of the sign.
To move this up you simply need to place a +5 to the outer right side of the absolute value.
What you should end up with: Y= - 1/3 |x+3| +5

Step-by-step explanation:
Yak Travel Agency arranges trips for climbing Mount Everest. For each trip, they charge an initial fee in addition to \$0.15$0.15dollar sign, 0, point, 15 for each vertical meter climbed. For instance, the price for climbing all the way to the summit, which is 350035003500 meters above the base of the mountain, is \$645$645dollar sign, 645.
Let yyy represent the fee (in dollars) of a trip where they climbed xxx vertical meters.
Complete the equation for the relationship between the fee and vertical distance.
Answer:
[tex]y = 120 + 0.15x[/tex]
Step-by-step explanation:
Given
[tex]Additional\ Fee = \$0.15[/tex] per vertical meter
[tex]y = fee[/tex] per x meter
[tex]x = vertical\ meter[/tex]
For:
[tex]x = 3500[/tex] --- [tex]y = 645[/tex]
Required
Determine the equation that relates y to x
Let the initial fee be represented with m
The equation that relates y to x is:
[tex]y = Initial\ Fee + Additional\ Fee * Vertical\ Meter[/tex]
This gives
[tex]y = m + 0.15 * x[/tex]
We need to first solve for m
From the question,
[tex]x = 3500[/tex] when [tex]y = 645[/tex]
So:
[tex]645 = m + 0.15 * 3500[/tex]
[tex]645 = m + 525[/tex]
Make m the subject
[tex]m = 645 - 525[/tex]
[tex]m = 120[/tex]
So, the initial fee is $120
Substitute 120 for m in [tex]y = m + 0.15 * x[/tex]
[tex]y = 120 + 0.15 * x[/tex]
[tex]y = 120 + 0.15x[/tex]
Hence, the required equation is: [tex]y = 120 + 0.15x[/tex]

Lynne was wondering which game was more popular so she aksed her friends which they liked to play more, FortNite or Among Us. She found that of the 80 people who responded, 0.55 of them preferred FortNite, and 30% of them preferred Among Us. How many more of her friends prefer FortNite than Among Us?
Answer:
20 more of her friends prefer FortNite than Among Us
Step-by-step explanation:
Lynne was wondering which game was more popular so she aksed her friends which they liked to play more, FortNite or Among Us.
She found that of the 80 people who responded:
For fortnite:
0.55 of them preferred FortNite
Hence, = 0.55 × 80 people
= 44 people preferred fortnite
For Among us
30% of them preferred Among Us.
= 30% × 80 people
= 30/100 × 80 people
= 24 people preferred Among us.
How many more of her friends prefer FortNite than Among Us?
This is calculated as:
44 - 24
= 20 more people
Hence, 20 more of her friends prefer FortNite than Among Us
Answer:
20 more of her friends prefer Forte than Among

Pythagorean Theorem: a2 + b2 = c2

Don’t mind the broken laptop
Answer:
c = [tex]\sqrt{90}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse c is equal to the sum of the squares on the other 2 sides, that is
c² = 9² + 3² = 81 + 9 = 90 ( take the square root of both sides )
c = [tex]\sqrt{90}[/tex]

perimeter = 36 calculate
the value of x when x-2 in
square
Answer:
11
Step-by-step explanation:
36/4 = 9
9 = x-2
x = 11
Step-by-step explanation:
Perimeter = 36
length = x - 2
Perimeter of a square = 4 × length
36 = 4(x - 2)
dividing through by 4:
9 = x - 2
hence:
x = 9 + 2 = 11.
