Answer:
The coordinates of the points on the unit circle help us to find the tangent of each angle. As you can see with this equation, the tangent of an angle is equal to the y-coordinate divided by the x-coordinate. For each angle, start by dividing each y-coordinate by the x-coordinate to get the tangent of that angle.

An isosceles triangle has an angle that measures 100°. What measures are possible for the
other two angles? Choose all that apply.
80 100 40 50
The only measure that is possible for the other two angles is 40 degrees.
What is triangle ?
Triangle can be defined in which it consists of three sides, three angles and sum of three angles is always 180 degrees.
Let's call the two other angles in the isosceles triangle "x". We know that the sum of the three angles in a triangle is always 180 degrees. Therefore, we can set up an equation:
100 + x + x = 180
Simplifying this equation, we get:
2x + 100 = 180
Subtracting 100 from both sides, we get:
2x = 80
Dividing both sides by 2, we get:
x = 40
So the other two angles must both measure 40 degrees.
None of the other choices (80, 100, or 50 degrees) are possible for the other two angles in an isosceles triangle with one angle measuring 100 degrees.
Therefore, the only measure that is possible for the other two angles is 40 degrees.

The sales team at an electronics store sold 48 computers last month. The manager at the store wants to encourage the sales team to sell more computers and is going to give all the sales team members a bonus if the number of computers sold increases by 30% in the next month. a) What is the amount of increase in computers needed? b)What is the new amount of computers the team must sell?
Answer: a. 14 Computers
b. 62 Computers
Step-by-step explanation:
a) What is the amount of increase in computers needed?
Number of Computers sold last month = 48
Percentage increase required = 30%
Amount of increase in computers needed= 30% × 48
= 0.3 × 48
= 14.4
= 14 approximately
b)What is the new amount of computers the team must sell?
This will be the amount of Computers sold last month plus the increase.
= 48 + 14
= 62 Computers

x=8.385
Step-by-step explanation:
Angle EBD is a right angle since it's facing the diameter ED
Hence triangle BED is a right isosceles triangle since we also know that EB=BD
so A is the midpoint of ED since it's the center of the circle and ED is a diameter
which implies ED=2×AD=2×6=12
Using the Pythagorean theorem on a right isosceles triangle which states:
a²+b²=c²
x²+x²=12²
2x²=144
x²=72
x=√72=8.485

every wrong answer. Sunil gets 6 correct answers and 4 wrong answers. What is his
score?
Answer this question right , then I will award u brainlist and points
16 points
Step-by-step explanation:Hi there !
What is his score?
6×4 - 4×2 =
= 24 - 8
= 16 points
Good luck !
Answer:
marks awarded for each correct answer = 4
marks awarded for each incorrect answer = -2
No.of Sunil's correct answer = 6
therefore, mark of Sunil's correct answer = 6 x 4 = 24
No.of Sunil's incorrect answer = 4
therefore, mark of Sunil's incorrect answer = 4 x -2 = -8 (here + and - is multiplied therefore the final answer will be -)
Sunil's total score = 24(positive marks) - 8(negative marks)
=24-8 = 16

Bella was out at a restaurant for dinner when the bill came. Her dinner came to $24. After adding in a tip, before tax, she paid $29.04. Find the percent tip.
Answer:
21%
Step-by-step explanation:
So we have to use percent change
The formula is subtracted/original multiply 100=percent change
so she added a $5.04 tip
5.04/24=0.21, then multiplied by 100=21
so she tipped 21%

A castle has to be guarded 24 hours a day. 7 knights are ordered to split each day's guard duty equally. How long will each knight spend on duty? Record your answer in minutes
Answer:
≈206 Minutes
Step-by-step explanation:
We know that the castle has to be guarded for 24 hours a day. Since there are 60 minutes in an hour, that means it must be guarded for 1,440 minutes (60 * 24 = 1,440). If we split this evenly between each of the 7 knights, through division, we know that they must each be on guard for 205.714285714 minutes, or approximately 206 minutes.

The solution of the linear equations y = -x + 3 and y = 4x - 2 will be (1, 2). Then the correct option is B.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equations are given below.
y = -x + 3 ...1
y = 4x - 2 ...2
From equations 1 and 2, then we have
4x - 2 = - x + 3
4x + x = 2 + 3
5x = 5
x = 1
Then the value of 'y' is given as,

Your cafeteria line requires 8 minutes on the average for each customer to proceed through the line and pay the cashier. The average time space between each customer is 30 seconds. If the line is open for 1 1/2 hours for lunch, how many customers can you serve for lunch?
Answer:
You can serve 81 customers for lunch during the 11,5 hours opening.
Step-by-step explanation:
11,5 hours is 690 minutes.
Each customer takes 8,5 minutes (8 + 0,5)
690 / 8,5 = 81,17
As we can't serve "part" of customer:

A hotel has a rectangular shaped meeting room that is 13.4 yards wide and 15.1 yards long. If the carpenter cost $ 1.71 per feet² what would be the cost of carpenting the room ?
✯ Explanation -Given :
Length of the meeting room = 15.1 yardBreadth of the meeting room = 13.4 yardRate of carpenting per feet² = $ 1.71Need to find :
Cost of carpenting the room.Solution :
THIS QUESTION IS BASED ON MEANSURATION TO SOLVE THIS QUESTION FIRST WE WILL CALCULATE THE AREA OF THE MEETING ROOM AND THEN WE WILL CALCULATE THE COST OF CARPENTING THE MEETING ROOM.
Calculating the area of the meeting room
[tex] \star \: \large \boxed{\sf{ Area_{(rectangle)} = Length × Breadth }}[/tex]
[tex] \large\rm{ Area_{(rectangle)} = (15.1 × 13.4) yard² = 202.34 \: yards²}[/tex]
Area of the meeting room = 202.34 yard²
Calculating the cost of carpenting the meeting room
First we will convert yards into feet
We know,
1 yard = 3 feet
202.34 yard = 202.34 × 3 = 607.02 feet
Now calculating the cost of carpenting the meeting room
Rate of carpenting = $ 17.1 per feet²
Cost of carpenting = $ ( 17.1 × 607.02) = $10,380.04

(-4,1); perpendicular to y= -5/6x +3
Answer:
y = (6/5)x + 29/5
Step-by-step explanation:
To avoid confusion please enclose the fractional exponent inside parentheses: y= -5/6x +3 => y= (-5/6)x +3
The new line is to be perpendicular to the given line (above). The slope of this new line must be the negative reciprocal of (-5/6), which is (6/5).
Usig the slope-intercept formula, we get y = mx + b, or
1 = (6/5)(-4) + b
The LCD here is 5. Multiplying all 3 terms by 5, we get:
5 = 6(-4) + 5b, or
5 = -24 + 5b, or
5b = 29
Then b = 29/5, and the desired equation is:
y = (6/5)x + 29/5

Commutative Property of Addition (rearrange the added terms in the parentheses to group like terms together.)
5(2j + 3 + j)
Combine Like terms after rearranging them
(put your answer from the previous row here)
Distributive Property of multiplication over addition (multiply the number outside the parentheses)
(put your answer from the previous row here)
(Use this final expression that you write in this box on the next slide.)
Answer:
Commutative Property of Addition: to change the order of numbers in an addition or multiplication operation does not change the sum or the product.
New expression with property used: 5(2j + j + 3)
Combine like terms: when combining like terms, add their coefficients
The like terms are 2j and j. Add their coefficients: 2 + 1 = 3, which means that the combination of like terms is 3j.
New expression with property used: 5(3j + 3)
Distributive Property of multiplication over addition: multiplying a sum by a number gives the same result as multiplying each added term by the number and then adding the products together.
So 5(3j + 3) = 5 · 3j + 5 · 3 = 15j + 15
New expression with property used: 15j + 15

Answer:
Step-by-step explanation:
Let length be x
So breadth will be 1/4x
2(x+1/4x)=60
x+1/4x=60/2=30
find lcm and the lcm would be 4 and make denominators equal and add it
4/4x+1/4x=30
5/4x=30
x=30*4/50=6*4=24
Therefore the length is 24/4=6cm and breadth is 24cm.
