In the figure, if m ZABD = 120°, then mZADC =
0.
Answer:
m∠ADC = 132°
Step-by-step explanation:
From the figure attached,
By applying sine rule in ΔABD,
[tex]\frac{\text{sin}(\angle ABD)}{\text{AD}}=\frac{\text{sin}(\angle ADB)}{AB}[/tex]
[tex]\frac{\text{sin}(120)}{35}=\frac{\text{sin}(\angle ADB)}{30}[/tex]
sin(∠ADB) = [tex]\frac{30\text{sin}(120)}{35}[/tex]
= 0.74231
m∠ADB = [tex]\text{sin}^{-1}(0.74231)[/tex]
= 47.92°
≈ 48°
m∠ADC + m∠ADB = 180° [Linear pair of angles]
m∠ADC + 48° = 180°
m∠ADC = 180° - 48°
m∠ADC = 132°

Two times x is 16 more than y. The sum of x and two times y is 18.
find the value of y.
Step-by-step explanation:
We can make 2 equations as follows:
2x = y + 16 and x + 2y = 18
x + 2y = 18 is the same as x = 18 - 2y. Hence, 2(18 - 2y) = 2x = y + 16.
2(18 - 2y) = y + 16
36 - 4y = y + 16
5y = 20
y = 4.
Ed wants to build a small 800 square foot cabin on a lot that is 80 feet deep. If the building sideyard setbacks are 20 feet and the cabin is 20 feet wide, what is the square footage of the lot
Answer:
4800 ft²
Step-by-step explanation:
Given that :
Area of cabin = 800 ft²
Width of cabin = 20 feets
Side yard setback of building = 20 feets
Depth of lot = 80 feets
The cabin is a rectangle :
Area of rectangle = Length * Width
800 = length * 20
Length = 800 / 20 = 40 feets
Hence,
Width of lot = side yard + Width of cabin = (20 + 20) = 40 feets
Length of lot = depth +. Length of cabin = (80 + 40) = 120 feets
Area of lot = Length of lot * width of lot
Area of lot = 120 ft * 40 ft = 4800 ft²

Natalia is writing a recursive formula to represent the sequence.
8, 12, 18, 27, ...
What value should she use as the common ratio in the formula?
1/4, 2/3, 3/2, 4/1
Answer:
The answer to your equation would be 1.5.
Step-by-step explanation:
The common ratio if there exists one can be found by choosing a term and dividing by its previous term
So does 12/8=18/12=27/18? Put each into the calculator. If they are equal fractions then this sequence is geometric and has a common ratio.
Each of the fractions are equal to 1.5.
Therefore the commom ratio is 1.5.

Pleaseeeee helpppp !!!!!!!! Will mark Brianliest !!!!!!!!!!!!!
Answer:
so this uses proportions.
you need to find the side BF which is proportional to the side BF.
You do:
9/6=x/42
and cross multiply
9*42=6*x
378=6x
divide by 6 on both sides
x=63
the answer is 63
Answer:
These are similar triangles.
By changing the length of the base of the corresponding triangle, the 3 interior angles of this triangle remain equal to the original
Therefore, if these triangles are similar, their corresponding sides must give equal ratios to each other:
This means that BF/FE = BC/CD=FC/ED
The total length of line segment BD=BC+CD; BC=6, CD=42; BD=6+42, BD=48
BE=BF+FE; BE=9+?
if BF/FE=BC/CD then 9/BE=6/42; 6/42=3/21 or 1/7. 9/BE=1/7; 1/7=9/BE
1x9=9, 7x9=63
63=BE
Step-by-step explanation:
what is the value of p
Answer:

Identify each value of x that makes 11 + 2x < 13
Answer:
x < 1
Step-by-step explanation:
This is the answer because:
1) 11 + 2 = 13 and 13 is not less than 13, it is equal to 13. Therefore, x has to equal anything less than 1 because then only inequality statement will be true.
Therefore, the answer is x < 1.
Hope this helps! :D
The value of x that makes 11 + 2x < 13 is x < 1
Given:
11 + 2x < 13
< means less than
11 + 2x < 13
Subtract 11 from both sides11 + 2x - 11 < 13 - 11
2x < 2
divide both sides by 2x < 2/2
x < 1
x less than 1
Therefore, the value of x that makes 11 + 2x < 13 is x < 1

Jacob and Kerrie are trying to figure out how long they can live off their $84,670 savings if they spend $370 each month. They have each created an equation. Jacob's Equation Kerrie's Equation y = 84,670 + (370x) y = 84,670 − (370x) Which person has the correct equation to model this linear relationship?
A.Kerrie's equation is incorrect, because their spending will increase the amount of their savings. B.Kerrie's equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings. C.Jacob's equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings. D.Jacob's equation is incorrect, because their spending should be a fixed amount and should not be multiplied.
Answer:
B.)Kerrie's equation is correct because their spending will be multiplied by the number of months and then subtracted from their savings
Step-by-step explanation:
Given : Jacob and kerrie are trying to figure out how long they can live off their 84,670 savings if they spend 370 each month.
To Find: Which person has the correct equation to model this linear relationship?
Jacob's equation : y = 84,670+(370x).
Kerrie's equation : y=84,670-(370x).
Since they have 84670 in savings
They spend each month = 370
They spend in x months = 370x
So, spending this amount from saving they left with amount = 84,670-(370x)
Thus Kerrie's equation is correct .
Hence Option B is correct
B.)Kerrie's equation is correct because their spending will be multiplied by the number of months and then subtracted from their savings

Y= -2x+4 by graphing
Answer:
See attached file.
Step-by-step explanation:
This can be graphed by plugging in two distinct x values and solving each for y. That will give you two x,y coordinates to draw on the graph, which will let you trace the line defined by them.
You can get the points where the line intersects the axis by solving either variable for zero. Try giving x a value of 2 or 0 to find those.

Noel Magee purchased a micro-cut shredder at a sale price of $179.99. The regular selling price is $199.99. He also purchased a photo-smart printer at 25% off the regular price of $499.99. A. What is the markdown on the shredder? B. What is the markdown on the printer?
Answer:
a) 10% off or $20 off
b) 25% off or $124.99 off
Step-by-step explanation:
In order to find the markdown on the shredder we simply need to divide the sale price by the original price. Once we have that we subtract that decimal from 1 and multiply by 100 to get the markdown percentage. We can also subtract the original price from the sales price to get the markdown dollar value.
179.99 / 199.99 = 0.899
(1 - 0.899) * 100 = 10%
199.99 - 179.99 = $20
Now, for the printer we are provided the markdown perentage so to find the markdown dollar value we need to divide the perentage by 100 to turn it into a decimal and multiply that decimal by the regular price of the printer. We can also subtract the markdown dollar value from the original price to get the sale price...
25% / 100 = 0.25
0.25 * 499.99 = 124.99
499.99 - 124.99 = $375
