Answer:
Measures of all angles are 57°, 57°, 123°, 123°
Step-by-step explanation:
Given:
Sum of two angles = 114°
Find:
Measures of all angles
Computation:
Sum of all 4 angles = 360°
Sum of remain 2 angles = 360° - 114°
Sum of remain 2 angles = 246°
So, first two angles = 114° / 2 = 57°
Second two angles = 246° / 2 = 123°
So, measures of all angles are 57°, 57°, 123°, 123°

What is the probability of rolling a dice and getting either a 1 or 2 and flipping a coin and getting a heads?
Answer:
1/3 and 1/2
Step-by-step explanation:
This is approximately equal to 0.167
====================================================
Explanation:
A = event of getting either a 1 or 2
P(A) = probability event A occurs
P(A) = 2/6 = 1/3, since there are two ways to get "1 or 2" out of six total
B = landing on heads
P(B) = 1/2, there are two sides and only one is heads
P(A and B) = probability getting a 1 or 2 and flipping heads on a coin
P(A and B) = P(A)*P(B) .... only possible if A and B are independent
P(A and B) = (1/3)*(1/2)
P(A and B) = (1*1)/(3*2)
P(A and B) = 1/6

WILL REWARD BRAINIEST!!
Answer:
See below.
Step-by-step explanation:
Recall that the biggest angle will always be opposite from the biggest side.
IT is opposite from Angle S, which we can figure out to be 180-108-25=47.
SI is opposite from Angle T, which is 41.
ST is opposite from Angle I (the whole thing). Just from looking at it, we know that it is the biggest angle. If we want to figure it out, Angle I is 180-41-72+25=92.
The smallest side is SI, then IT, then ST.
The correct order is: SI, IT, and ST.
Ken started a savings account for school. He plans on spending 10% of the money he earns for leisure activities. He needs to have $2,160 in the bank before he starts school. how much must he earn to have the amount needed for school?
Answer:
$2,400
Step-by-step explanation:
Ken intends to start a savings account
10% = leisure spending
This means 90% = Expenses for school
Let us represent the amount he must save as : x
Hence in other for him to have $2,160 in his savings account, the amount Ken must earn is calculated as:
90/100 × x = $2,160
Cross Multiply
90x = $2,160 × 100
x = ($2,160 × 100) ÷ 90
x =$2,400
Therefore, the amount Ken has to earn to have the amount needed for school is $2,400
A group of tourists can be sorted into tour boats in groups of 4 or in groups of 6. In either case, there are no empty seats. Find the number of tourists if there are more than 25 and fewer than 45.
Answer: there are 36 tourists.
Step-by-step explanation:
Ok, we have two integer numbers:
T, the number of tourists and S, the number of seats.
Such that, if we divide the tourists into groups of 4 and in groups of 6, we end with no empty seats.
Knowing that the number S must be an integer, and when we divide T into groups of 4 and 6 we end with no empty seats, this means that T can be divided by 4 and by 6.
This means that T is a common multiple of 4 and 6
Now, we also know that 25 < T < 45.
Then let's see which ones are the multiples of 4 between 25 and 45.
4*7 = 28
4*8 = 32
4*9 = 36
4*10 = 40
4*11 = 44.
Now, the multiples of 6 in that range are:
6*5 = 30
6*6 = 36
6*7 = 42.
You can see that 36 is a common multiple, other way to see it is:
4*9 = (2*2)*(3*3) = 2*2*3*3 = (2*3)*(2*3) = 6*6
So the numer of tourist must be 36.

Natalia wants to attend Louisiana State University. One year at Louisiana State University costs approximately $24,000. She currently has $4,000 in savings. Natalia has received a one-time grant of $1,500 and an annual academic scholarship for $3,500. She plans to enroll in the work study program that will pay $12,000 annually for part-time work. How much will Natalia need to borrow in student loans in order to attend Louisiana State University for 4 years?
Answer:
He needs to borrow $28,500 to attend the University for 4 years.
Step-by-step explanation:
One year at the University costs $24,000. The total she has to pay are 4 * $24,000 = $96,000
minus the $4,000 she has in savings: $96,000 - $4,000 = $92,000
minus the $1,500 she received one time: $92,000 - $1,500 = $90,500
minus $3,500 per anual
4* $3,500 = $14,000
$90,500 - $14,000 = $76,500
minus $ 12,000 per anual
4 * $12,000 = $48,000
$76,500 - $48,00 = $28,500

Assignment: The Discriminant
Part I: Practice Finding the Discriminant
Find the value of the discriminant for each quadratic equation below. Show all steps needed to
write the answer in simplest form, including substituting the values of a, b, and cin the
discriminant formula. Then use the value to determine how many real number solutions each
equation has.
1.
x + 6x-3.0
2. 3x + 2x+1=0

Answer:
1. D = 48, two; 2. D = -8, none; 3. D = 0, one
4.D = 81, two; 5. D = -91, none; 6. D = 49, two
Step-by-step explanation:
The formula for a quadratic equation is
ax² + bx + c = 0
The quadratic formula gives the roots:
[tex]x = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a} = \dfrac{-b\pm\sqrt{D}}{2a}[/tex]
D is the discriminant.
It tells us the number of roots to the equation — the number of times the graph crosses the x-axis.
[tex]D = \begin{cases}\text{positive} & \quad \text{2 real solutions}\\\text{zero} & \quad \text{1 real solution}\\\text{negative} & \quad \text{0 real solutions}\\\end{cases}[/tex]
It doesn't matter if the graph opens upwards or downwards.
If D > 0, the graph crosses the x-axis at two points.
If D = 0, the graph touches the x-axis at one point.
If D < 0, the graph never reaches the x-axis.
1. x² + 6x - 3 =0
a= 1; b = 6; c= -3
D = b² - 4ac = 6² - 4×1×(-3) = 36 - 4(-3) = 36 + 12 = 48
D > 0: two real solutions
2. 3x² + 2x + 1 = 0
a = 3; b = 2; c =1
D = b² - 4ac = 2² - 4×3×1 = 4 - 12 = -8
D < 0: no real solutions
3. x² + 4x + 4 = 0
a = 1; b = 4; c =1
D = 4² - 4×1×4 = 16 - 16 = 0
D = 0: one real solution
4. 5x² + x = 4
5x² + x - 4 = 0
a = 5; b = 4; c = -4
D = 1² - 4×5×(-4) = 1 - 20(-4) = 1 - (-80) = 1 + 80 = 81
D > 0: two real solutions
5. 5x² - 3x = -5
5x² - 3x + 5= 0
a = 5; b = -3; c = 5
D = (-3)² - 4×5×5 = 9 - 100 = -91
D < 0: no real solutions
6. x² - x = 12
x² - x - 12= 0
a = 1; b = 1; c = -12
D = 1² - 4×1×(-12) = 1 - 4(-12) = 1 + 48 = 49
D > 0: two real solutions

Answer:
y > 4/3 x - 2.
Step-by-step explanation:
First find the equation of the dashed line:
The slope (-6-2)/(-3-3)
= -8/-6
= 4/3.
y - y1 =m(x - x1) where m = slope and (x1,y1) is a point on the line.
y - 2= 4/3(x - 3)
y = 4/3(x - 3) + 2
y = 4/3 x - 2

Answer:
x = 6
y = 4
Step-by-step explanation:
Let the two numbers be x and y
Condition 1:
7x+3y = 54 -----------(1)
Condition 2:
x = 2+y -----------------(2)
Putting (2) in (1)
=> 7(y+2)+3y = 54
=> 7y+14+3y = 54
=> 10y = 54-14
=> 10y = 40
Dividing both sides by 10
=> y = 4
Now putting y = 4 in eq(2)
=> x = 2+4
=> x = 6

Use the diagram to find the angle measures.
Find m∠1, m∠3, and m∠4 if m∠2=117°.
Find the measures of all four angles if m∠2+m∠4=220°.
Answer:
1.) m∠1 = 63 degree
m∠3 = 63 degree
m∠4 = 117 degree
m∠2 = 117 degree
2.) m∠1 = 70 degree
m∠3 = 70 degree
m∠4 = 110 degree
m∠2 = 110 degree
Step-by-step explanation:
Given that
1.) m∠2 = 117°.
In the figure, m∠1 is vertically opposite to m∠3, and m∠4 is vertically opposite to m∠2
Therefore, m∠2 = m∠4 = 117° ( because vertically opposite angle are equal)
Also, the sum of angles at a point is equal to 360 degrees
m∠2 + m∠4 = 234°
Take 234 away from 360. That is,
360 - 234 = 126
126/2 = 63 degrees.
Therefore, m∠1 = m∠3 = 63°
2.) If m∠2 + m∠4 = 220°
Subtract 220 from 360 since the sum of angles at a point is equal to 360 degrees
360 - 220 = 140
Divide 140 by 2 and also 220 by 2 to get
140/2 = 70 and 220/2 = 110
Therefore,
m∠1 = 70 degree
m∠3 = 70 degree
m∠4 = 110 degree
m∠2 = 110 degree

Find the angle measure given the figure is a rhombus.
Answer:
Angle 1 = 156°
Step-by-step explanation:
The angle opposite 12 is also equal to 12 because the rhombus is split into two congruent triangles.
The other part about a rhombus is that the line angles in half meaning that where 12 is cut in half, the full angle is 24.
With this info, we now know that the other two angles that are in the triangle with angle 1 have a sum of 24°
Subtract: 180 - 24 = 156°
