one angle of a triangle is 60 degree and the other two are in the ratio 2:3.Find these angles
Answer:
48 and 72 degrees.
Step-by-step explanation:
The sum of the other 2 angles = 180-60 = 120 degrees.
So they are 2 / (2+3) * 120 = 2/5 * 120 = 48 and 3/5 * 120 = 72 degrees.
If there were 80 points scored overall, how many of them were scored by Bridgette? she scored 5% of the points
Answer: she scored 4 points
Step-by-step explanation: 5% of 80=4
;-----------;
Answer:
4 points were scored by bridgette
Step-by-step explanation:
80 times 5 equal 400
Then you move the decimal point to the left by the number of digits the whole number has. In this case, it only has 2, so we move the decimal point 2 spaces over to the left.. Therefore, 400 becomes 4.00. 4.00 is the same as 4, so 4 is your answer.

What value of x is in the solution set of 2x-3 > 11 - 5x?
Answer:
x ≤ 3
Step-by-step explanation:
Answer:
The value of x is 2.
Step-by-step explanation:
The key to this solution is to combine like terms.
2x-3 > 11-5x
There are lots of ways to combine them but the way I think would be the most simple would be to avoid negative numbers (although I personally enjoy it) but anyways,
First, you can add 5x to both sides of the inequality.
This would cancel out 5x and leave you with: 7x-3 > 11
The next terms that you can combine can be the constants. You can combine -3 and 11 and to do that, you add 3 on both sides. That would cancel 3 out and leave you with: 7x > 14
Now, the last step is to get x by itself and to do that, you divide 7 on both sides to get:
x > 2
I hope my explanation wasn't too confusing for you

(Round to the nearest tenth.)
Enter your answer in the answer box and then click Check Answer.
All parts showing
Answer: The height of the building = 14.5 feet.
Step-by-step explanation:
Given: Length of ladder = 15 feet
Distance of base of ladder from building = 4 feet
Since building is standing vertical on ground making right angle.
So with ladder a right triangle is formed , where base = 4 feet , Hypotenuse = 15 feet [Hypotenuse is side opposite to right angle]
According to the Pythagoras theorem ,
Hypotenuse² = Perpendicular² + Base²
⇒ (15)² = Perpendicular² + (4)²
⇒ 225 = Perpendicular² +16
⇒ Perpendicular² = 225 -16
⇒ Perpendicular² = 209
⇒ Perpendicular = √209 = 14.4568322948 ≈ 14.5 feet
Hence, the height of the building = 14.5 feet.

the formula for a parallelogram is A=b*h
x+ y + z = -3
3y - Z = 4
2x- y - 2z = -5
Answer:
(-3, 1, -1)Step-by-step explanation:
x + y + z = -3 --> (1) 3y - z = 4 --> (2)2x - y - 2z = -5 --> (3)Add up (1) and (2)
x + 3y + y + z - z = -3 + 4 ⇒ x + 4y = 1 --> (4)Double (2) and subtract from (3)
2x - y - 2z - 2(3y - z) = -5 - 2(4) ⇒ 2x - y - 2z - 6y + 2z = -5 - 82x - 7y = -13 --> (5)Double (4) and subtract (5)
2(x + 4y) - 2x + 7y = 2 + 13 ⇒ 2x + 8y - 2x + 7y = 15 ⇒ 15y = 15 ⇒ y = 1Finding x
x + 4(1) = 1 ⇒ x = 1 - 4 ⇒ x = -3Finding z
-3 + 1 + z = -3 ⇒ z = -1So the answer is:
(-3, 1, -1)(01.01 MC)Why is 2 + (−3) equal to −1? Because it is 3 units to the left of 2 on a horizontal number line Because it is 3 units to the right of 0 on a horizontal number line Because it is 3 units to the left of 0 on a horizontal number line Because it is 3 units to the right of 2 on a horizontal number line
Answer:
Because it is 3 units to the left of 2 on a horizontal number line
Step-by-step explanation:
Given
[tex]2 + (-3) = -1[/tex]
Required
Why?
The interpretation of the question is that:
[tex]2 + (-3) = -1[/tex]
What is the result when 2 is shifted 3 units in the negative direction (i.e. towards the left)?
First, we have a horizontal to have the the following representation:
<.....-4 -3 -2 -1 0 1 2 3 4 5 ......>
Taking the positions of 2 and -1 into consideration,
<.....-4 -3 -2 -1 0 1 2 3 4 5 ......>
We can see that the distance between 2 and -1 is 3 units towards the left
In other words, -1 is 3 units from 2 in the left direction
Hence, option A answers the question
Answer:
Because it is 3 units to the left of 2 on a horizontal number line

At the city museum child admission is $5.40 and adult admission is $9.40. On Wednesday, 168 tickets were sold for a total sales of $1199.20. How many adult tickets were sold that day?
Given:
Selling price of child ticket = $5.40
Selling price of adult ticket = $9.40
Total tickets = 168
Total sales = $1199.20
To find:
The number of adult tickets sold.
Solution:
Let x be the number of child tickets and y be the number of adult tickets.
Total tickets : [tex]x+y=168[/tex] ...(i)
Total sales : [tex]5.40x+9.40y=1199.20[/tex] ...(ii)
From equation (i), we get
[tex]x=168-y[/tex]
Put this value in (ii).
[tex]5.40(168-y)+9.40y=1199.20[/tex]
[tex]907.2-5.40y+9.40y=1199.20[/tex]
[tex]4y=1199.20-907.2[/tex]
[tex]4y=292[/tex]
Divide both sides by 4.
[tex]y=\dfrac{292}{4}[/tex]
[tex]y=73[/tex]
Therefore, 73 adult tickets were sold that day.

Answer:
a) correct
b) needs parentheses: -1, (1±i√2)/3
Step-by-step explanation:
a) You can factor by grouping:
(x³ -2x²) -(5x -10) = x²(x -2) -5(x -2) = (x² -5)(x -2)
Roots are ±√5, 2.
__
b) The sum of odd-degree coefficients is equal to the sum of even-degree coefficients (3-1 = 1+1), so one root is x=-1. Factoring out that leaves the quadratic factor ...
3x³ +x² -x +1 = (x +1)(3x² -2x +1)
The quadratic formula can be used on the quadratic factor to find its roots:
x = (-(-2) ±√((-2)²-4(3)(1)))/(2(3)) = (2 ±√-8)/6 = (1 ±√-2)/3
Roots are -1, (1 ±i√2)/3.

Androcles
adapted from Aesop’s Fables
scene 1:
(Backdrop—forest. Enter Androcles looking over his shoulder)
ANDROCLES: (Speaking to himself) I’ve just escaped from my master. I need to find a place to hide. (As he searches for a place to hide, he sees a lion moaning in pain. He turns to run but changes his mind.) Oh! You poor thing. (He looks at the lion’s paw, which is swollen and bleeding. He finds a large thorn, which is the cause of the pain, pulls it out, and binds the paw. The lion rises and licks Androcles's hand. The lion leads him to a cave stage right.)
ANDROCLES: (Speaking to the audience) The lion brought me meat to live on for the next few days until we were captured.
(Curtain)
scene 2:
(Backdrop—arena. The Emperor enters stage right downstage and moves to stage left upstage. Androcles is surrounded by guards who enter from stage right upstage. Androcles moves to center stage. His head is bowed.)
EMPEROR: The slave shall be thrown to the lion as punishment. Ensure that the lion has a good appetite.
(The Emperor and the members of court are gathered stage left upstage. Androcles is center stage. The lion charges in from stage rightdownstage. Androcles steps back. The lion recognizes Androcles and begins to lick his hand.)
EMPORER: (Surprised) What is this? Guards! I wish to speak with him. (Speaking to Androcles) How did you do that? Are you a sorcerer?
ANDROCLES: (Bowing to the emperor) When I escaped and ran into the forest, I found him with a large thorn. It caused him much pain. I took it out, and he has been grateful since then.
EMPORER: (Impressed) Very well! You are pardoned and the lion shall be released into the wild.

1)) Norachai school is selling tickets for the annual talent show. On the first day of ticket sales, the school sold 5 adult tickets and 4 student tickets for a total of $ 85. The school received $ 55 on the second day selling 5 adult tickets and 2 student tickets. What is the price of each adult and student ticket?
9514 1404 393
Answer:
adult: $5student: $15Step-by-step explanation:
If we let 'a' represent the price of an adult ticket, and 's' represent the price of a student ticket, the two sales can be described by ...
5a +4s = 85
5a +2s = 55
Subtracting the second equation from the first gives ...
(5a +4s) -(5a +2s) = (85) -(55)
2s = 30 . . . . simplify
s = 15 . . . . divide by 2
Substituting this into the second equation, we have ...
5a +2(15) = 55
5a = 25 . . . . subtract 30
a = 5 . . . . . divide by 5
Each adult ticket sold for $5; each student ticket sold for $15.
The probability of college graduate getting employed within a year is 90 % 90%. The probability of a college graduate getting employed and buying a car within a year is 72 % 72%. What is probability that a college graduate bought a car within a year given that he got employed within a year?
Answer:
Step-by-step explanation:
Let the probability of getting employed after graduated within a year be P(A)
and the probability of buying a car within a year be P(B)
Given that:
The probability of getting employed after graduated within a year = 90% = 0.9
Then; Let that be P(A)
The probability of getting employed and buying a car within a year = 72% = 0.72.
Then; Let that be P(A∩ B).
The probability that a college student will get both events is P(B/A)
[tex]P(B/A) = \dfrac{P(A \cap B) }{P(A)}[/tex]
[tex]P(B/A) = \dfrac{0.72}{0.90}[/tex]
P(B/A) = 0.80
