Who knows this, Find m∠UTS, if m∠UTV=x+15, m∠VTS=140∘, and m∠UTS=15x+15
Answer:
165
Step-by-step explanation:
First, m<UTS=m<UTV+m<VTS by Angle Addition Postulate. Then, you substitute all the values that you provided for the angles. 15x+15=x+15+140. You then solve for x.
15x+15=x+155
14x=140
x=10
You then plug back in 10 for X in the value of m<UTS. 15(10)+15=165

What is the domain of f(x) = 3x – 2? {x | x > 0} {x | x < 0} {x | x = 0} {x | x is a real number}
Answer:
Option (4). {x | x is a real number}
Step-by-step explanation:
Domain of any function is defined by the x values (Input values) and range by the y-values (Output values).
Given function is f(x) = 3x - 2
When we graph this function, we get a straight line.
That means the given function is defined for all real numbers.
Therefore, domain of this function will be all real numbers.
Domain: {x | x is a real number}
Option (4) will be the answer.
Answer:
D) {x | x is a real number}

Answer:
A
Step-by-step explanation:
1st graph is the same for all choices.
3d graph is horizontal line y=50 or C(x) = 50.
It is A or B choices.
We have white circle , that means value of x is not included x > 6.
It is A.
We can check the 2d line. By continuing line we can see that y -int = 10, and we can see slope= rise/run = 5. Also, 2<x≤ 6.
Answer:
It's the first option.
Step-by-step explanation:
Note that the filled circles means that the value is included in the inequality and the clear circle means it is not.
For the first 2 Gb ( 0 to 2 inclusive) used, the cost is $15.
Then for x > 2 up to and including x = 6 ( that is 6 Gb used) it rises at a rate of 5 dollars per Gb + $10, so its 5x + 10 for 2 < x <= 6.
Then the cost stays at $50.
Which expression is represented by the number line?
A number line going from negative 4 to positive 4. An arrow goes from negative 2.5 to negative 1, from 0 to 3, and from 3 to negative 2.5.
3 – 5.5 – 1.5
3 – 5.5 + 1.5
3 – 2.5 – 1
3 – 2.5 + 1
Answer:
3 – 5.5 + 1.5
Step-by-step explanation:
The number line described above is 3 – 5.5 + 1.5
Starting from our midpoint '0'
It moves 3 units to the right direction = +3
Then from that point '+3', it moves to '-2.5' which is 5.5 units to the left = -5.5. Then finally moves from '-2.5' to to '-1' which is 1.5 units towards the right direction = +1.5
Therefore, we finally have ;
+3 - 5.5 + 1.5
Answer:
B) 3 - 5.5 + 1.5

5x+7x+12x= 21624x= 216x= 9small : medim : large = 45 : 63 : 108
45y+63*2y+108*3y= 648.45y(45+126+324)= 648.45495y= 648.45y= 648.45/495y= £1.31 profit for small cakeAnswer:
£1.31
Step-by-step explanation:
The cakes are sold in the ratio 5 : 7 : 12 = 5x : 7x : 12x ( x is a multiplier )
sum the parts of the ratio, 5x + 7x + 12x = 24x
Equate 24x to the number of cakes sold, that is
24x = 216 ( divide both sides by 24 )
x = 9
Thus cakes sold are
5x = 5 × 9 = 45 small cakes
7x = 7 × 9 = 63 medium cakes
12x = 12 × 9 = 108 large cakes
let p represent the profit on a small cake, then
45p + 63(2p) + 108(3p) = 648.45 , that is
45p + 126p + 324p = 648.45
495p = 648.45 ( divide both sides by 495 )
p = 1.31
That is the profit on one small cake is £1.31
Noah visits different states every summer. This summer, he started with 2 states already visited and visits 6 states per day. Write an equation to model this situation (use d for days and s for states)

Find a value for Ф in radians between 2π² if sin(Ф) = -1/2 and cos(Ф) = √3/2 (Unit Circle)
Answer:
This is the angle in the angle in the fourth quadrant that verifies the given conditions:
[tex]\phi =\frac{11\, \pi}{6} \\[/tex]
Step-by-step explanation:
Notice that in the unit circle, if sin of the angle is negative, and cos of the same angle is positive, we are in the fourth quadrant.
Also, the angle that renders
[tex]sin(\phi)=-\frac{1}{2}[/tex]
in the fourth quadrant, is [tex]\phi =\frac{11\, \pi}{6} \\[/tex]
for such angle, also :
[tex]cos(11 \pi/6)=\frac{\sqrt{3}}2}[/tex]

The Nth term of a sequence is 3n^2/2
a) what is the second term of the sequence?
b) what is the fifth term sequence?
c) which term in the sequence is the first to have a value higher than 50?
Please help
The second and fifth term for the given sequence are 6 and 48 respectively and a₆ > 50.
What is an inequality expression?An inequality expression refers to the relation between an algebraic expression to some known value that contains inequality sign. Unlike an equation it can have a range of values inside an interval.
The given problem can be solved as,
(a) The nth term of the sequence is given as aₙ = 3n²/2
Then, substitute n = 2 to get second term as below,
a₂ = (3 × 2²)/2 = 6
(b) The fifth term is obtained as,
a₅ = (3 × 2⁵)/2 = 48.
(c) The inequality expression for the given case can be written as,
3n²/2 > 50
⇒ 3n² > 100
⇒ n² > 33.33
This is possible only for n = 6.
Hence, the second and fifth terms are 6 and 48 respectively. And, the 6th term will be the first to be greater than 50.

HOW CAN YOU USE SUBTRACTION TO DESCRIBE DIVISION? GIMME AN EXAMPLE PLS :(
Answer:
By repeated subtraction.
Step-by-step explanation:
It is pretty much the same thing as division, but in subtraction. Since, Dividing and Subtraction are a like, repeated subtraction is a great example to use for this example
Hope this helps. :)
Answer:
kk so like, division is just repeated subtraction. like idk say you have 36 and you divide it by 9 so I think you just keep subtracting 9 until you reach 0? so you end up subtracting 9 four times which happens to be the quotient for 36/9. yeah. it's almost like how multiplication is just repeated addition.

If you are asked to graph y = 3x + 1, or y = x2 - x - 6, or y = x3 - 3, do you think it is a good idea to start by plugging in zeros? That is, to let x = 0 and then let y = 0? Why or why not?
Answer:
I think you should start with a table and then write all your points for x then in the next column your answers for y.
Then take your medium and start drawing.
I suggest your x's should start from 0 and increase by 1 or 2
Then when you reach a certain point then go back to 0 and start doing your negatives.
For example if y = 2x
x | y
0|0
1 | 2
2| 4
3|6
4|8
....
then
16|32
0|0

A bag contains 5 blue marbles, 6 red marbles, and 4 green marbles. You select one marble at random from the bag. What is P(blue)?
Answer:
P(blue) = 1/3 (Answer)
Step-by-step explanation:
Probability for any event A is given by
p(A) = no of times of happening of event A/ total no of occurrence of all the event given under the situation.
____________________________________
A bag contains 5 blue marbles, 6 red marbles, and 4 green marbles
So, total no of occurrence of all the event given under the situation
one can either pick blue , red or 4 green marbles
Total no. of occurrence of all the event = 5 + 6 + 4 = 15
Now , no of occurrence of selecting blue.
since there are 5 blue marbles, there is chance of selecting blue is 5.
no of occurrence of selecting blue = 5
Therefore,
P(blue) = no of occurrence of selecting blue /total no of occurrence of picking any color ball
P(blue) = 5/15 = 1/3 (Answer)

You roll a twelve-sided die (having values one through twelve on its faces). What is the probability that the value of the roll will be a composite number?
show work pls!
Step-by-step explanation:
If a die is rolled once, determine the probability of rolling a 4: Rolling a 4 is an event with 1 favorable outcome (a roll of 4) and the total number of possible outcomes is 6 (a roll of 1, 2, 3, 4, 5, or 6). Thus, the probability of rolling a 4 is .
If a die is rolled once, determine the probability of rolling at least a 4: Rolling at least 4 is an event with 3 favorable outcomes (a roll of 4, 5, or 6) and the total number of possible outcomes is again 6. Thus, the probability of rolling at least a 4 is = .
Angle sum theorem
25°
30°
Answer:
x = 125°
y = 180-125 = 55°
Step-by-step explanation:
The angles should sum to 180 in a triangle.
Since the other two are 25 and 30, for the third one, 180-25-30 = 125 is left, which is x.
Now y and x are supplementary angles, which means that x+y is also 180°.
So y = 180-x = 55°
Answer:
y = 55°
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
y is an exterior angle of the triangle, thus
y = 25° + 30° = 55°

Hey so im really confused on how to rewrite problems into radical form, so I was wondering if anyone would be able to show me how to do It step by step?
Answer:
Step-by-step explanation:
Ok so, I'll try to make this explanation super simple for you.
The denominator will always go on the outside and the numerator will be on the inside. Let me give you an example.
Take x^2/3. The answer will be 3√(x^2). Do you see how the 3 is on the outside and the 2 is on the outside?
Take p^4/5. The answer will be 5√(p^4).
I hope this gives you a clear understanding.
