A new bank customer with $3,000 wants to open a money market account. The bank is offering a simple interest rate of 1.4% What will the account balance be after 10 years
The account balance after 10 years is $7200.
How to calculate the interest?It should be noted that simple interest is calculated as:
= (Principal × Rate × Time) / 100
= ($3000 × 1.4 × 10) / 100
= $4200
The total amount that will be in the account will be:
= Principal + Interest
= $3000 + $4200
= $7200

A salesman bought a computer from a manufacturer. The salesman then sold the computer for $15600 making a loss of 25%. What amount did the salesman pay the manufacturer for the computer?
The amount that the salesman pay the manufacturer for the computer is $20800.
How to calculate the value?From the information, the salesman sold the computer for $15600 making a loss of 25%.
The amount that the salesman pay the manufacturer for the computer will be illustrated thus:
Since a 25% loss was made, the cost price will be: = 100% + 25% = 75%
Therefore, the cost price will be:
= Sales price / 125%
= $15600 / 0.75
= $20800
The amount is $20800.

Solve it find the slope!
Write an equation in slope-intercept form of the line that passes through the given point and is parallel to the graph of the given equation. the ordered pair (2, - 2) y = -x - 2.
The equation of the parallel line is y = -x
How to determine the line equation?The equation is given as
y = -x - 2
The point is also given as
point = (2, -2)
The equation of a line can be represented as
y = mx + c
Where
slope = m
By comparing the equations, we have:
m = -1
This means that the slope of y = -x - 2 is -1
The slopes of parallel lines are equal
This means that the slope of the other line is -1
The equation of the parallel line is then calculated as
y = m(x - x₁) +y₁
Where
m = -1
(x₁, y₁) = (2, -2)
So, we have
y = -1(x - 2) - 2
Open the brackets and evaluate
y = -x
Hence, the parallel line has an equation of y = -x

Answer:
Step-by-step explanation:
Hi, you are studying trigonometry :P nice
conterminal means stopping at the same place, right? sooo what is the same place for 659° compared to our only once around the circle of 360° since 720° is twice around a circle our 659° is less than that so just subtract 360° from 659° to get the co-terminal angle.
659-360=299°
299° is the co-terminal angle
270 is the line between the 3rd and 4th quadrant, so this is definitely in the 4th quadrant.
let's just count backwards (CW) from zero degrees till we get to our 299° angle going in the forward (CCW) direction. so 299-360= -61°
the reference angle is 61°

Richard’s cumulative gpa for 3 semesters was 2. 0 for 42 credits. His fourth semester gpa was 4. 0 for 14 course units. What is richard’s cumulative gpa for all 4 semesters?.
Richard earned a cumulative GPA of 2.5 in all four semesters.
Here, we know that the cumulative GPA for the first 3 semesters is 2.0
He had earned 42 credits in total in all three semesters.
Cumulative GPA = Total points earned/credits rewarded
Hence,
Total points earned in 3 semestes= 2 X 42
= 84 points
In the fourth semester,
he had earned 14 credits with a GPA of 4.0
Hence total points earned = 4 X 14
= 56 points
Therefore, total points earned in all four semesters = 84 + 56 points
140 points
Total credits = 14 + 42
= 56
Hence, the cumulative GPA of all 4 semesters
= 140/56
= 2.5 points.

The length of the ramp is [tex]\sqrt{410}[/tex] inches.
According to the question,
We have the following information:
A ramp is elevated to a height of 7 inches from the base. The horizontal distance between the lower end of the ramp and the base is 19 inches.
So, it will be a right-angled triangle.
Now, we can use Pythagoras theorem to find the length of the ramp which is the hypotenuse of the triangle.
Let's denote the length of the ramp to be l, elevated height to be p and horizontal distance to be b.
[tex]l^{2} =p^{2} +b^{2}[/tex]
[tex]l^{2} =7^{2} +19^{2}[/tex]

The value of x for the given triangle is 4.5
What is a triangle?A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.
The sum of all three angles of a triangle is always 180°
In the given triangle ABC,
∠A=(9x+16)°, ∠B=(6x+15)°
And the extrior angle ∠C=(19x+3)°
Use the external angle property,
The sum of two interior angles is equal to an exterior angle.
Therefor,
∠C=∠A+∠B
(19x+3)°=(9x+16)°+(6x+5)°
19x+3=15x+21

alex buys 4 cups of coffee and 3 cups of tea. he paid a total of £6.95.
Ben buys 5 cups of coffee and 2 cups of tea. He pays a total of £7.20.
work out the total cost of each cup of coffee in the cost of each cup of tea
Answer:
Step-by-step explanation:
Assume the cost for a cup of coffee is x and the cost for a cup of tea is y.
For Alex: 4x+3y=6.95
For Ben 5x+2y=7.20
Then multiply Alex's cost by 2 and Ben's by 3 to cancel y.
8x+6y=13.90
15x+6y=21.60
Equation 2 minus equation 1 would be
15x+6y-(8x+6y)=15x+6y-8x-6y=7x
21.60-13.90=7.70
7x=7.70
Then x=1.10 and plugging it one of the equations,
y= 0.85
A cup of coffee costs 1.10 pounds and A cup of tea is 0.85 pounds

A linear function h models a relationship in which the dependent variable increases 1 unit for every 5 units the independent variable decreases. The value of the function at 0 is 3.
The given linear function is [tex]f (h) = - \frac{1}{5} x + 3[/tex]. The graph is attached at the end.
Let the independent variable be x.
It is given in the question:
Value of the function, h at 0 = 3
Thus, h(0) =3
Also, when the independent variable decreases by 5, the dependent variable increases by 1.
So, slope = -[tex]\frac{1}{5}[/tex]
y-intercept = 3
We know the linear equation is-
y = mx + b ... (i)
where y ⇒ linear function
m ⇒ slope of the line
x ⇒ independent variable
b ⇒ y-intercept

A) Write an equation that models the amount of storage as a function of the number of songs
B) Interpret the slope and t-intercept of the line of fit
pls include work
a) An equation that models the amount of storage as a function of the number of songs is y = -0.005x + 16
b) Slope of the equation is -0.005 and the intercept of the equation is 16
Slope intercept form
Slope intercept form presents the graph of a straight line and is represented in the form of
y = mx + c.
where
y = y coordinate
m = slope
x = x coordinate
b = y intercept
Given,
Here we have the table shows the amount of storage y (in gigabytes) on a music-playing device when there are x songs on the device
Now, we have to find the following:
a) Equation of the table
b) Slope and intercept.
In order to find the equation, we have to identify the slope an intercept of the table.
So, to find that we have to take two points from the table.
Then the selected points are
(0, 16), (242, 14.8)
By using these point we have to calculate the slope as,
m = (14.8 - 16) / (242 - 0)
m = -1.2/242
m = -0.005
Now, the intercept is calculated by using the point (0, 16) and the slope -0.005, then we get,
16 = -0.005(0) + c
c = 16
Therefore, the equation is y = -0.005x + 16.

The quadrilateral with vertices (0,0), (5,0), (8,4), and (3,4) is a rhombus.
What is a rhombus?
A quadrilateral with all equal sides is a rhombus. Rhombuses are a particular kind of parallelogram in which all of the sides are equal since the opposite sides of a parallelogram are equal.
What is a distance formula?
D = √(x₂ - x₁)² + (y₂ - y₁)²

Given vertices A(0,0), B(5,0), C(8,4), and D(3,4)
By applying the distance formula, we get
AB = √(5 - 0)² + (0 - 0)² = 5
BC = √(8 - 5)² + (4 - 0)² = 5
CD = √(3 - 8)² + (4 - 4)² = 5
