Answer:
450 + 16.83[tex]x[/tex]
x = the number of overtime hours worked.
Answer:
y = 16.83x + 450
Step-by-step explanation:
y - the amount earned
x - the hours worked overtime
450 is a constant, it is a value that is always present, and doesn't change or depend on anything. 16.83 is a coefficient whose value needs to be multiplied by the x value to hold true in the equation.

Simple Interest
Compounded Quarterly
Compounded Monthly
Answer:
Compounded Quarterly
Step-by-step explanation:
This is because the compound interest equation is dependent on the number of times the amount is compounded per year. Monthly is 12 times per year and quarterly is only 4. Simple interest stays at a linear rate.

Answer:
X = -10/6
X = -1,666666666666667
Step-by-step explanation:
First at all you join the X's

A cyclist rode 3.75 miles in 0.3 hours At that rate, how long will it take her to go 4.5 miles?
Answer:1)Distance covered by cyclist=3.75 miles.
Time =0.3 hours.
Speed= Distance ÷Time
Speed =3.75÷0.3=12.5 miles per hour.
2) Speed = 12.5 miles per hour, Distance = 4.5 miles .
Time = Distance ÷Speed.
Time = 4.5÷12.5=0.36 hours.
Time taken to cover 4.5 miles is 0.36 hours.
Answer: 0.36
Step-by-step explanation:
4.5 divided by 12.5
4.5 divided by 12.5 =
= 0.36
3. What is the perimeter of VPQR? Show your work. (Giving Brainliest)!
Answer:
13 (i think)
Step-by-step explanation:
Answer:
P = 17
Step-by-step explanation:
3y – 2 = y + 4
3y -2 (+2) = y + 4 (+2)
3y = y + 6
3y (-y) = y (-y) + 6
2y = 6
2y / 2 = 6 / 2
Y = 3
PR = 3y – 2
PR = 3(3) – 2
PR = 9 – 2
PR = 7
P of PQR = 4 + 6 + 7
P of PQR = 17
2.
The vertices of APQR have coordinates P(2,3),
Q(3,8), and R(7,3). Under which transformation
of APQR are distance and angle measure
preserved?
(1) (x,y) - (2x, 3y)
(2) (x,y) - (x + 2, 3y)
(3) (x,y) (2x, y + 3)
(4) (x,y) - (x + 2, Y + 3)
Answer:
(1) (x,y) - (2x, 3y)
(2) (x,y) - (x + 2, 3y)
(3) (x,y) (2x, y + 3)
(4) (x,y) - (x + 2, Y + 3)
that its
The distance and angle measure of ΔPQR are preserved by the transformation (x, y) → (x + 2, y + 3).
What is Triangle?Triangles are three sided polygons in the two dimensional geometry. It has three vertices, three angles and three sides.
Vertices of the triangle PQR are P(2, 3), Q(3, 8) and R(7, 3).
Length of side PQ = √[(3 - 2)² + (8 - 3)²] = √26
Length of side QR = √[(7 - 3)² + (3 - 8)²] = √41
Length of side PR = √[(7 - 2)² + (3 - 3)²] = 5
If the transformation of (x, y) → (x + 2, y + 3) is done, vertices are P'(4, 6), Q'(5, 11) and R'(9, 6).
Length of P'Q' = √[(5 - 4)² + (11 - 6)²] = √26
Length of Q'R' = √[(9 - 5)² + (6 - 11)²] = √41
Length of P'R' = √[(9 - 4)² + (6 - 6)²] = 5
That is, lengths of sides are equal when the transformation is done. So since all sides are equal, angle measure will also be equal.
Hence by the transformation (x, y) → (x + 2, y + 3), the distance and angle measure of ΔPQR are preserved.

A bucket holds b liters of water. But a jar holds 8 fewer liters than the bucket. How many times can the bucket hold than the jar? Thanks for your help!
Answer:
b / (b - 8)
Step-by-step explanation:
Given that :
Litres of water held by bucket = b
Jar holds 8 litres fewer than bucket; hence, litres held by jar = b - 8
The number of times bucket can hold than jar is :
Litres held by bucket / litres held by jar
b / (b - 8)
in southern California, there is a six-mile section of Interstate 5 that increases 2,500 feet in
elevation. What is the angle of elevation?
Answer:
4.51°
Step-by-step explanation:
1 mile= 5280 feet
6 mile= 6(5280) =31680 feet
Angle of elevation is 0 where
tan 0 = 2500/ 31680 = 0.0789
Hence 0 = tan-1(0.0789) = 4.51°

write a coordinate proof. Given: Rectangle ABCD has vertices A(0,4), B(6,4), C(6,0), D(0,0). E is the midpoint of line DC. F is the midpoint of line DA. Prove: The area of rectangle DEGF is one fourth the area of rectangle ABCD.
Please help I've been trying for a while
Answer:
The answer is below
Step-by-step explanation:
Distance between two points [tex]A(x_1,y_1)\ and\ B(x_2,y_2)\ on \ the\ coordinate\ plane[/tex]
[tex]|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The area of rectangle = length * breadth
The area of rectangle ABCD = |AB| * |BC|
[tex]|AB|=\sqrt{(6-0)^2+(4-4)^2}=6\\\\|BC|=\sqrt{(6-6)^2+(0-4)^2} =4[/tex]
The area of rectangle ABCD = |AB| * |BC| = 6 * 4 = 24
E(x, y) is midpoint of line DC. Its coordinate is:
x = (6 + 0) / 2 = 3; y = (0 + 0) / 2 =0
The coordinate of E = (3, 0)
F(a, b) is midpoint of line DA. Its coordinate is:
a = (0 + 0) / 2 = 0; b = (4 + 0) / 2 = 2
The coordinate of E = (0, 2)
The area of rectangle DEGF = |DE| * |DF|
[tex]|DE|=\sqrt{(3-0)^2+(0-0)^2}=3\\\\|DF|=\sqrt{(0-0)^2+(2-0)^2} =2[/tex]
The area of rectangle ABCD = |DE| * |DF| = 3 * 2 = 6
Therefore, area of rectangle DEGF is one fourth the area of rectangle ABCD
Tanya read 12 books for extra credit. She received 3.5 points for each nonfiction book and 1.5 points for each fiction book. If she received 28 extra credit points, how many of each kind of book did Tonya read?
Answer:
Tanya read 5 nonfiction books and 7 fiction books.
Step-by-step explanation:
Given that:
Number of books read by Tanya = 12
Points for nonfiction book = 3.5
Points for fiction book = 1.5
Total credit points received = 28
Let,
x be the number of nonfiction book read
y be the number fiction books read
According to given statement;
x+y=12 Eqn 1
3.5x+1.5y=28 Eqn 2
Multiplying Eqn 1 by 1.5
1.5(x+y=12)
1.5x+1.5y=18 Eqn 3
Subtracting Eqn 3 from Eqn 2
(3.5x+1.5y)-(1.5x+1.5y)=28-18
3.5x+1.5y-1.5x-1.5y=10
2x=10
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{10}{2}\\x=5[/tex]
Putting x=5 in Eqn 1
5+y=12
y=12-5
y=7
Hence,
Tanya read 5 nonfiction books and 7 fiction books.
