Answer:
15 hours
Step-by-step explanation:
Given
Direct variation between y and x
Where x represents hours and y represents number of buttons
y = 2450 when x = 7
Required
Solve for x when y = 5250
Since it's a direct variation, we have that
2450 buttons = 7 hours
5250 buttons = x
Cross Multiply both expressions
2450 * x = 7 * 5250
2450x = 36750
Divide through by 2450
x = 36750/2450
x = 15
Hence, it'll take 15 hours to manufacture 5250 buttons
Required

Use the figure to find the measures of the numbered angles.
∠1 =
∘
∠2 =
∘
Step-by-step explanation:
The given angle is 107°;
Since the lines given are parallel and a transversal cuts them, angle 1 and 107° are corresponding angles.
Corresponding angles are equal;
So, ∠1 = 107°;
Now, ∠1 and ∠2 are angles on a straight line;
∠1 + ∠2 = 180°
107° + ∠2 = 180°
∠2 = 180° - 107° = 73°
Answer: <1= 107 <2=73
Step-by-step explanation: Zigzag method for <1
<1+<2=180
180-<1=<2
180-107=73

The ratio of left-handed students to right-handed students in 8th grade is 1:5. If there are 85 right-handed students in this class, how may left-handed students would there be?
Answer: There would be 17 Left-handed students
Step-by-step explanation: I know there's a common core way to do this by doing cross multiplication with 1/5 x "x"/85 (x being the answer) but this question is simple enough to just divide 85 by 5

Does the following relationship represent a function?
yes Step-by-step explanation:
The given relation in the mapping diagram represents a function.
What is function in mathematics ?A function in mathematics is an expression with a independent variable (x) in it. The variable is called independent because it is not dependent on any value to get its value. Function also has a dependent variable (y) whose value depend on x. Ex -
y = f(x) = ax + d
We have a relation as shown in the figure.
The given relation is a function as all the values of [x], has independent values of [y]. Two or more values of [x] can have same value of y.
Therefore, the given relation in the mapping diagram represents a function.

savings
Total
$2362
Sammy has included a total row to help make sure that his paycheck can be divided to make deposits into these 4
Answer:
B
Step-by-step explanation:
Based on the amount that Sam saves and his living expenses, the amount he needs to save and the length of time it will take him to do so is B. 5,136; Approximately 24 months.
What are Sam's living expenses?= Fixed essential expenses + Variable essential expenses
= 1,292 + 420
= $1,712
How much does Sam need to save?Sam needs to save three times his expenses:
= 1,712 x 3
= $5,136
How long will it take Sam to save this amount?= Amount to be saved / Amount saved monthly
= 5,136 / 210
= 24 months approximately.
________________________________________________________
The question is:
Using his essential expenses as a guideline, how much will Sammy need to save if he wants to have 3 times the amount of his living expenses in the bank as part of his emergency savings. How long will it take him to achieve his goal?
a. $1,712; approximately 8 months
b. $5,136; approximately 24 months
c. $6,486; approximately 30 months
d. $2,162; approximately 6 months

e. find the XY coordinates of point g with the center k
use the image to find the answers for each part mathematics high school done
Answer:
a. tan∠FKG = √3
b. tan∠BKG = 1
c. [tex]tan\angle KDF = \dfrac{1}{\sqrt{3} }[/tex]
d. tan∠BCK = 1
e. The coordinates of the point g is (4, 4·√3)
Step-by-step explanation:
a. The trigonometric ratio for tan is given as follows;
[tex]tan\angle X = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length}[/tex]
Therefore, we have;
[tex]tan\angle FKG = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length} = tan(60^{\circ}) = \dfrac{sin(60^{\circ})}{cos(60^{\circ}) } = \dfrac{\dfrac{\sqrt{3} }{2} }{\dfrac{1}{2} } = \sqrt{3}[/tex]
b.
[tex]tan\angle BKG = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length} = tan(45^{\circ}) = \dfrac{sin(45^{\circ})}{cos(45^{\circ}) } = \dfrac{\dfrac{1 }{\sqrt{2} } }{\dfrac{1}{\sqrt{2} } } = 1[/tex]
c.
[tex]tan\angle KDF = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length} = tan(30^{\circ}) = \dfrac{sin(30^{\circ})}{cos(30^{\circ}) } = \dfrac{\dfrac{1 }{2 } }{\dfrac{\sqrt{3} }{2 } } = \dfrac{1}{\sqrt{3} }[/tex]
d. In right triangle, ΔBKC, ∠BCK = ∠BKC = 45°
∴ tan(∠BCK) = tan(45°) = 1
e. The x-coordinate of the point g is 4
The y-coordinate of the point g is 4 × tan(60°) = 4·√3
The coordinates of the point g is (4, 4·√3).
