Find the gradients of lines A and B
Answers
Step-by-step explanation:
[tex]the \: gradient \: of \: line \: a \: is[/tex]
[tex]m = \frac{4}{1 } \\ m = 4[/tex]
[tex]the \: gradient \: of \: line \: b \: is[/tex]
[tex]m = \frac{ - 2}{1} \\ m = - 2[/tex]
Gradients of line A is equals to [tex]4[/tex] and gradients of line B is equals to [tex]-2[/tex].
What is gradients?" Gradients is defined as the ratio of difference of y-coordinates to the difference of x-coordinates."
Formula used
Gradients [tex]= \frac{y_{2}- y_{1}}{x_{2}- x_{1}}[/tex]
According to the question,
Given from the graph,
Coordinates of Line A
[tex](x_{1} ,y_{1} ) = ( 3,3)\\\\(x_{2} ,y_{2} ) = ( 4,7)[/tex]
Substitute the value in the formula we get,
Gradient of line A [tex]= \frac{7-3}{4-3}[/tex]
[tex]= 4[/tex]
Coordinates of Line B
[tex](x_{1} ,y_{1} ) = ( -1,3)\\\\(x_{2} ,y_{2} ) = ( -2,5)[/tex]
Gradient of line B [tex]= \frac{5-3}{-2-(-1)}[/tex]
[tex]= -2[/tex]
Hence, gradients of line A is equals to [tex]4[/tex] and gradients of line B is equals to [tex]-2[/tex].

Sean has a beginning balance of $328.15 in his account. He writes checks for the following amounts: $20.75, $43.58,
$30.45, and $29.72. What is the new balance in Sean's account?
$14.75
$203.65
$124.50
$307.40
Answers
Answer:
The new balance in Sean's account is $203.65
Step-by-step explanation:
The initial balance in Sean's account is $328.15. Then he writes checks for the amounts $20.75, $43.58, $30.45, and $29.72.
The sum of his checks is $20.75 + $43.58 + $30.45 + $29.72 = $124.5
The new balance in Sean's account is the initial balance minus the sum of the amounts of the checks he wrote:
Final balance = $328.15 - $124.5 = $203.65
The new balance in Sean's account is $203.65

In a box of chocolates, 1/5 of the chocolates contain nuts.
The rest of the chocolates do not contain nuts.
Write down the ratio of the number of chocolates that contain nuts to number of chocolates that do not contain nuts.
Give your answer in the form of 1:n
Answers
Answer:
The ratio of the number of chocolates that contain nuts to the number of chocolates = 1:4
Step-by-step explanation:
The parameters given are;
Proportion of the box of chocolates that contain nuts = 1/5
Proportion of the box of chocolates that do not contain nuts = 1 - 1/5 = 4/5
Therefore, we have in a box of chocolates with five chocolates;
The number of chocolates that contain nuts = 1
The number of chocolates that do not contain nuts = 4
Which gives the ratio of the number of chocolates that contain nuts to the number of chocolates as 1:4.

What is the length of the hypotenuse of the triangle when x= 12?
6x+4
5x
The length of the hypotenuse is about
(Round to the nearest tenth as needed.)
Answers
Answer:
The length of the hypotenuse: c = 96.8 units
Step-by-step explanation:
Given the sides
a = 6x+4b = 5xc = hypotenuse = ?Given that the x = 12
so
a = 6x+4 = 6(12)+4 = 76b = 5x = 5(12) = 60Pythagorean Theorem:
For a right angled triangle with sides 'a' and 'b', the hypotenuse 'c' is defined as:
[tex]c=\sqrt{a^2+b^2}[/tex]
substituting a = 76 and b = 60
[tex]c=\sqrt{76^2+60^2}[/tex]
[tex]c=4\sqrt{586}[/tex]
[tex]c = 96.8[/tex] units
Therefore, the length of the hypotenuse: c = 96.8 units

Match the lines m and n to the statements they represent
Answers
Answer:
Line n: A set of points where the coordinates of each point have a sum of 2
Line m: A set of points where the y-coordinate of each point is 10 less than the x-coordinate
Step-by-step explanation:
Given
Lines m and n (See attachment)
Required
Interpret both lines
First, we pick few coordinates of line m and then line n.
For m
[tex](x_1,y_1) = (13,3)[/tex] -- At point E
[tex](x_2,y_2) = (6,-4)[/tex] -- At point B
[tex](x_3,y_3) = (2,-8)[/tex] -- At point D
For n
[tex](x_1,y_1) = (-2,4)[/tex] -- At point A
[tex](x_2,y_2) = (6,-4)[/tex] -- At point B
[tex](x_3,y_3) = (12,-10)[/tex] -- At point C
Test for Statement A:
Set of point with a sum of 2
i.e.
[tex]x + y = 2[/tex]
For m
[tex](x_1,y_1) = (13,3)[/tex] -- At point E
[tex]x_1 + y_1 = 13 + 3 = 16[/tex]
This statement is not true for line m
For n
[tex](x_1,y_1) = (-2,4)[/tex] -- At point A
[tex]x_1 + y_1 = -2 + 4 = 2[/tex]
[tex](x_2,y_2) = (6,-4)[/tex] -- At point B
[tex]x_2 + y_2 = 6- 4 = 2[/tex]
[tex](x_3,y_3) = (12,-10)[/tex] -- At point C
[tex]x_3 + y_3 = 12- 10 = 2[/tex]
This statement is true for line n
Test for Statement 2:
Set of points where y is x - 10
i.e.
[tex]y = x - 10[/tex]
For m
[tex](x_1,y_1) = (13,3)[/tex] -- At point E
[tex]y_1 = x_1 - 10[/tex]
[tex]3 = 13 - 10[/tex]
[tex]3 = 3[/tex]
[tex](x_2,y_2) = (6,-4)[/tex] -- At point B
[tex]y_2 = x_2 - 10[/tex]
[tex]-4 = 6 - 10[/tex]
[tex]-4 = - 4[/tex]
[tex](x_3,y_3) = (2,-8)[/tex] -- At point D
[tex]y_3 = x_3 - 10[/tex]
[tex]-8 = 2 - 10[/tex]
[tex]-8 = -8[/tex]
This statement is true for line m

Traveling upstream (against the current) in a boat, you can travel 35 miles in 7 hours. It
takes half the time (3.5 hours) to travel the same distance downstream (with the
current). Find the speed of the current.
Answers
Answer:
The speed of the current is 2.5 miles per hour
Step-by-step explanation:
Systems of Equations
Let's call:
B = velocity of the boat
C = velocity of the current
When traveling upstream, the current is against the boat thus the relative velocity is B-C.
The distance is the product of the velocity by the time. Since the boat takes 7 hours to travel 35 miles upstream, thus:
d=(B-C)*7=35
Dividing by 7:
B - C = 5 [1]
When traveling downstream, the current and the boat are collaborative and the relative velocity is B+C. The travel takes now 3.5 hours, thus:
d=(B+C)*3.5=35
Dividing by 3.5:
B + C = 10 [2]
Subtracting [2] - [1]:
2C = 5
C = 5/2 = 2.5
The speed of the current is 2.5 miles per hour
Identify the initial amount and the growth rate of the following:
Y = 9.8 (1.35)^t
Answers
The initial amount is when t = 0, so it is 9.8 * 1 = 9.8. The growth rate is how much the amount goes up by for every increase of 1 in t. This is 1.35 because that is the part being affected by t. we plug in 0 for t to get 9.8 as the initial amount. The growth rate is just 135% factor, or 35% more each time, because 1.35 is the base of the exponent.

(d) 7%
Answers
Answer:
a) $1920, b) $2880, c) $4320, d) $6720
Step-by-step explanation:
a) Interest = Principal(Rate)(time)/100
Interest = $8000(12)(2)/100
Interest = $1,920
b) Interest = $8000(3)(12)/100
Interest = $2880
c) Interest = $8000(4.5)(12)/100
Interest = $4320
d) Interest = $8000(7)(12)/100
Interest = $6720
