Lines AB and CD are straight lines. Find x and y. Give reasons to justify your solution
Answers
Answer:
x = 18
y = 54
Step-by-step explanation:
90 - 72 = 18
18 + 2x = 3x
18 = x
2(18) = 36
3(18) = 54
72 + y + 54 = 180
126 + y = 180
y = 54

Chose the missing side length and the trigonometric ratio you would use to calculate.
Answers
Answer:
The missing value is 2.9mm and cosine was used
Step-by-step explanation:
Given triangle is a right-angled triangle we can use trigonometric ratios to calculate the missing length.
In the given triangle,
Base = k
Hypotenuse = 15mm
Angle = 79
We will use trigonometric ratio which includes base and hypotenuse.
Using cosine,
[tex]cos\ (angle) = \frac{Base}{hypotenuse}\\cos\ 79 = \frac{k}{15}\\k = cos\ 79 * 15\\k = 0.1908*15\\k = 2.862[/tex]
Rounding off to nearest tenth
[tex]k= 2.9mm[/tex]
Hence,
The missing value is 2.9mm and cosine was used

what is the exact value of x
Answers
Answer:8^1/6*2^x=32^1/2
We move all terms to the left:
8^1/6*2^x-(32^1/2)=0
Domain of the equation: 6*2^x!=0
x!=0/1
x!=0
x∈R
We get rid of parentheses
8^1/6*2^x-32^1/2=0
We calculate fractions

Noel works as a driver for a transportation company. On average, he drives 152 hours to make 19 successful deliveries. Assume this rate is his constant rate for delivering goods. If you graph this relationship with time along the x-axis and number of deliveries along the y-axis, the slope of the line you get gives Noel's unit rate for a successful delivery. Which unit rate can be interpreted as the slope?
a: 8 deliveries per hour
b :2/17 of an hour per delivery
c: 1/8 of a delivery per hour
d: 1/8 of an hour per delivery
Answers
Answer:
A
Step-by-step explanation:
By doing the unit rate, dividing 19 on both the top and bottom, getting this 8.36.../1, you can just round it to 8/1, meaning he makes about 8 deliveries per hour. Hope this helps!

Which two statements describe how saving $200 every month in her traditional 401(k) retirement account is different from saving $200 every month for her car? Select all the correct answers. Isabel’s retirement savings are made with after-tax dollars. Isabel’s retirement savings are made with pretax dollars. Isabel’s retirement savings can be used for other purposes without penalty. Isabel’s retirement savings have more liquidity than the money in her savings account. Isabel’s retirement savings have no contribution limits. Isabel’s retirement savings may include a contribution from her employer.
Answers
Answer:
Isabel’s retirement savings are made with pretax dollars.
Isabel’s retirement savings may include a contribution from her employer.
Step-by-step explanation:
When you contribute to an IRA account, your contribution is tax deductible. This means that all the money that you contribute to your account comes from pretax dollars. This contribution is limited to $19,500 per year (for 2020) or $26,000 if you are 50 or older.
Your employer can also contribute to your 401(k) account and employer's contribution may be even higher than the employee's. Total contributions including employer's and employee's cannot exceed $57,000 per year (or $63,500 if 50 or older) or the employee's total compensation per year, whichever is lower.

A game room has a perimeter of 70 ft. The length is 5 more than twice the width. How many feet squared of new carpeting should be ordered?
Answers
Answer:
A = 250 square ft
Step-by-step explanation:
Equations
Let's call:
x = width of the game room
The length is 5 more than twice the width, thus:
2x+5 = length of the game room
The perimeter of a rectangle is twice the sum of the width and the length:
P = 2( x + 2x + 5 )
And the perimeter is 70 ft:
2( x + 2x + 5 ) = 70
Operating:
2( 3x + 5 ) = 70
Dividing by 2:
3x + 5 = 35
Subtracting 5:
3x = 30
Dividing by 3:
x = 30 / 3
x = 10
The width is 10 ft and the length is 2(10)+5=25 ft
The area of the game room is:
A = 10 ft * 25 ft
A = 250 square ft

Answers
Answer:
Option B 6x-7y = -11 is correct
Step-by-step explanation:
We need to write the equation of the given line in standard form.
The points are (1/2,2) and (3,1)
The equation used is:
[tex]y-y_{1}=m(x-x_{1})[/tex]
where m is the slope.
Finding slope :
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
x₁= 1/2, y₁=2, x₂=-3, y₂=-1
Putting values:
[tex]m=\frac{-1-2}{-3-1/2} \\m=\frac{6}{7}[/tex]
Now taking point (1/2,2) and slope m = 6/7 finding equation:
[tex]y-y_{1}=m(x-x_{1})y-2=\frac{6}{7}(x-\frac{1}{2})\\ 7(y-2)=6(x-\frac{1}{2})\\7y-14=6x-3\\7y-6x=-3+14\\7y-6x= 11\\Multiply \,\,with\,\, -1\\-7y+6x=-11\\6x-7y=-11[/tex]
So, Option B 6x-7y=-11 is correct

Equation of this line in standard form:
6x − 7y = −11
Given points:
(-3, -1) ; (1/2 , 2)
We need to write the equation of the given line in standard form.
The points are (1/2,2) and (-3,-1)
The equation used is:
(y - y1) = m (x - x1)
m = slope = y2 - y1 /x2 - x1
Now,
(-3,-1) : (x1 , y1)
(1/2,2) : (x2 , y2)
m = slope = y2 - y1 /x2 - x1
m = 2- (-1)/ 1/2 - (-3)
m = 6/7
Substitute the values in the standard form,
y - (-1) = 6/7 [x- (-3)]
⇒6x−7y=−11
Hence
Equation of this line in standard form:
6x − 7y = −11

The students count the number of cases that are packaged on each assembly line over several minutes.
Answers
The unit rate for canned juice, in cases per minute is; 50 cases per minute is; cases per minute
How to find the unit rate?From the attached file, we see that it is a graph showing canned juice on the y-axis and time taken in minutes on the x-axis.
Now, to find the unit rate also means to find the slope from 2 defined points. From the given graph, we will take the coordinates;
(1, 50) and (2, 100)
Thus;
Slope = (100 - 50)/(2 - 1)
Slope = 50 cases per minute
Thus, the unit rate for canned juice, in cases per minute is; 50 cases per minute.
