Answer:
[tex]O_3=90[/tex]
Step-by-step explanation:
Recursive formula of a sequence has been given as,
[tex]O_1=6[/tex]
[tex]O_{n+1}=3(O_n+3)[/tex]
We have to find the value of [tex]O_3[/tex]
For n = 2,
[tex]O_2=3(O_1+3)[/tex]
[tex]O_2=3(6+3)[/tex]
= 27
For n = 3,
[tex]O_3=3(O_2+3)[/tex]
= 3(27 + 3)
= 3(30)
= 90

Solve the right triangle. Round decimal answers to the nearest tenth. I can´t figure out KL and ML.
Answers
Answer:
Me to I need that Answer en m<k is 50°
Step-by-step explanation:
The measure of KL is 5.1 unit and the measure of ML is 6.1 unit.
What are trigonometric ratios?The sides and angles of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
Given that, MK=8 units, ∠M=40° and ∠K=50°.
We know that, sinθ=Perpendicular/Hypotenuse
Now, sin40°=KL/8
0.6427=KL/8
KL=0.6427×8
KL=5.1 units
sin50°=ML/8
0.7660=ML/8
ML=6.1 units
Therefore, the measure of KL is 5.1 unit and the measure of ML is 6.1 unit.

A line with what type of slope contains the points (-2, 5) and (-2, 6)?
Answers
Answer:
undefined
Step-by-step explanation:
To find the slope
m = ( y2-y1)/(x2-x1)
= ( 6-5)/( -2 - -2)
= (6-5) /(-2+2)
= 1/0
We cannot divide by zero, so the slope is undefined

Four friends shared 3 orders of chicken wings. • Alex ate 5 of an order. ·8· • Chase ate 7 of an order. ·8· • Ella ate 6 of an order. ·8· How much chicken is left for the fourth friend?
Answers
Answer: 3/4
Step-by-step explanation:
Amount of chicken ordered = 3
Fraction eaten by Alex = 5/8
Fraction eaten by Chase = 7/8
Fraction eaten by Ella = 6/8
The chicken ate by the three friends will be:
= 5/8 + 7/8 + 6/8
= 18/8
= 2 2/8
= 2 1/4
Now, the chicken left for the forty friend will be:
= 3 - 2 1/4
= 3/4

Complete question :
Kenny is putting a brick border around his irregular shaped garden. Before installing the border, Kenny must
cut the bricks to fit the angles of the garden. Use the given measures to answer the question.
mzA=x
mZB=(5x-5)
m2C =(2x +20)
mZD=(3x-15)
mZE =(4x)
What are the angle measures of each vertex of the garden? Show your work.
Answer:
m<a=36
m<b=175
m<c=92
m<d=93
m<e=144
Step-by-step explanation:
Use the given measures to answer the question. MZA= x mZB = (5x – 5)º M2C = (2x+20)° m_D = (3x –15)° MZE = (4x)
We are given five angles :
Using the sum of interior angle of a regular polygon formula :
180(n - 2) ; where, n = number of sides ;
180(5 - 2) = 180 * 3 = 540°
The sum of the 5 angles should add up to 540°
x + (5x - 5)° + (2x + 20)° + (3x - 15)° + 4x = 540
5 + 20 - 15 + 5x + 2x + 3x + 4x + x = 540
15x = 540
15x = 540
15x = 540
x = 36
mzA= 36°
mZB=(5(36)-5) = 175°
m2C =(2(36) +20) = 92°
mZD=(3(36)-15) = 93°
mZE =(4(36) = 144°

Answers
Answer:
b=70 degrees
Step-by-step explanation:
a= 8x+6. b= 4x+38
a=b alternate exterior
combine like terms
8x+6=4x+38
Subtract 4x from both sides and 6
4x=32
Divide by 4
x=8
Plug in= 8 for B equation
b= 4(8)+38
b=70 degrees
Answer:
x = 8
m∠B = 70°
Step-by-step explanation:
The alternate exterior angles theorem states that m∠A and m∠B are the same. So,
8x + 6 = 4x + 38
Subtract 6 from both sides.
8x = 4x + 32
Subtract 4x from both sides.
4x = 32
Divide both sides by 4.
x = 8
Now to find the measure of m∠B, substitute x = 32 into 4x + 38.
8 * 4 + 38 =
32+ 38 = 70
m∠B = 70°
Just in case, let's double check our answer. Because m∠A is equal to m∠B, m∠A should be equal to 70.
70 = 8x + 6
70 = 8 * 8 + 6
70 = 64 + 6
70 = 70
Thus, x = 8 and m∠B = 70° is true.
I hope this helps! Feel free to ask any questions!
Gerald takes his family out to dinner. Garrett orders a pepperoni and mushroom pizza and a 16 oz drink. Gerald and his wife, Maggie, each order a chicken wrap. When the bill comes Maggie says she has a 10% off coupon. The waiter reminds them there is a 7% tax. Gerald decides to leave a 20% tip on the amount before coupons and taxes. What is the total cost including tax and tip?
Answers
But we’ll call the original bill x.
After the 10% off coupon, the bill is 0.9x
Adding tax = 0.07(0.9x) + 0.9x
Adding a tip = 0.20[0.07(0.9x) + 0.9x)]
