Mason wants to borrow $6,700 from the bank to purchase a car. If he borrows the money at a rate of 5% interest for 4 years, what is the total amount he will have to pay back to the bank?
Your answer should be in whole dollars. Do not add cents. Example: $4 not $4.00
Answer:
$8040Step-by-step explanation:
It is assumed as simple interest.
The amount of interest is:
5%*4 = 20% of $6700, which is6700*20/100 = 1340The amount paid back is the sum of the loan and interest:
6700 + 1340 = 8040Which values are solutions to the inequality below? Check all that apply.

The solutions to the equation sin(x + pi/2) = 1/2 in the interval [3pi/2, 2pi] are x = 5pi/3 and x = 4pi/3.
What is trigonometry?
Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles.
We can solve this equation using the following steps:
Subtract pi/2 from both sides to get sin(x) = 1/2.
Recall that the sine function is positive in the first and second quadrants.
Therefore, we need to find the angles in these quadrants where sin(x) = 1/2.
The two angles in the first quadrant where sin(x) = 1/2 are pi/6 and 5pi/6. The two angles in the second quadrant where sin(x) = 1/2 are 7pi/6 and 11pi/6.
Adding pi/2 to each of these angles gives the solutions to the original equation. These solutions are:
x = pi/6 + pi/2 = 2pi/3
x = 5pi/6 + pi/2 = 7pi/6
x = 7pi/6 + pi/2 = 5pi/3
x = 11pi/6 + pi/2 = 4pi/3
We now need to check which of these solutions lie in the interval [3pi/2, 2pi]. We find that the solutions in this interval are:
x = 5pi/3
x = 4pi/3
Therefore, the solutions to the equation sin(x + pi/2) = 1/2 in the interval [3pi/2, 2pi] are x = 5pi/3 and x = 4pi/3.

SOLVE THE SIMULTANEOUS EQUATION
3y=6x+3 and 3y=4x+6
Answer:
x=3/2
y=4
Step-by-step explanation:
3y=6x+3
3y=4x+6
we see that 3y=3y so even the right side of the equations are equal.
6x+3=4x+6
6x-4x=6-3
2x=3
x=3/2
so easily we find y
we found that x=3/2 so
3y=6*(3/2)+3=9+3=12
y=12/3=4
so the solution of simultaneous equation is
x=3/2
y=4

Suppose a math class starts at the beginning of the school year with 12 boys and 8 girls. However, after school resumed in January, 6 new boys and 4 new girls came to the class. Is the ratio of boys to the total number of students in the class still the same?
Answer:
yes the ratio is the same
Step-by-step explanation:
12/8 = 3/2 (divided the top and bottom by 4)
6/4 = 3/2 (divided the top and bottom by 2)
yes the ratio is the same
Answer:
To compare, first find out what the ratio of boys to students is at the beginning of the school year: 12/8 or, in the simplest form, 3/2.Once school resumes in January, that ratio becomes 18/12 - (12 + 6)/(8 + 4) - or 3/2 in simplest form.Therefore, the ratio is still the same.

let please help me please
Answer:
p = 170
Setting up the formula:
The mean is the sum of the digits divided by the total digits in the set.
[tex]\rightarrow \dfrac{\text{Sum of digits}}{\text{Total digits}} = \text{Mean}[/tex]
[tex]\rightarrow \dfrac{\text{Sum of digits}}{\text{Total digits}} = 39[/tex] [Mean = 39]
[tex]\rightarrow \dfrac{25 + p}{\text{Total digits}} = 39[/tex] [Sum of digits = 25 + p]
[tex]\rightarrow \dfrac{25 + p}{5} = 39[/tex] [Total digits = 5]
Step-by step calculations:
Use cross multiplication:
[tex]\rightarrow 25 + p= 39 \times 5[/tex]
Simplify the RHS:
[tex]\rightarrow 25 + p= 39 \times 5[/tex]
[tex]\rightarrow 25 + p= 195[/tex]
Subtract 25 both sides:
[tex]\rightarrow p = 195 - 25[/tex]
[tex]\rightarrow p = 170[/tex]

Answer: 8 gallons of water are being used per day.
Step-by-step explanation: If the question is how many gallons of water are used a day, then you can find this out using the following steps:
3 divided by 9 = 1/3.
1/3 times 24 = 8
8 gallons of water are being used per day.
Point W(-4, 7) was translated as follows: W(-4, 7) – W'(-2, 4). A student wrote the algebraic rule to describe the
translation as (x,y) → (x-3.y+2). Evaluate the student's answer.
A. Incorrect; the student should add 2 to the x-coordinate and subtract 3 from the y-coordinate.
B. Incorrect; the student should add-4 +-2 to calculate the x-coordinate and add 7 + 4 to calculate
the y-coordinate.
C. Incorrect; the student should add 3 to the x-coordinate and subtract 2 from the y-coordinate.
D. The student's answer is correct.
Answer:
A
Step-by-step explanation:
W (- 4, 7 ) → W' (- 2, 4 )
- 4 → - 2 in the x- directions is a shift of + 2
7 → 4 in the y- direction is a shift of - 3
then translation rule should be
(x, y ) → (x + 2, y - 3 )

jenny is drafting a paper on her computer. she leaves a right margin that is one-fifth the width of the page for later editing marks. on the
computer, each inch is equivalent to the length of 120 pixels. what is the area of the drafting section on the screen?
The area of the drafting section on the screen after Jenny left a right margin for editing marks is 1,077,120 pixels.
What is the area of the drafting section?The first step is to determine the dimensions of the drafting section:
Length = 11 inches
Width = (1 - 1/5) x 8.5 = 6.8 inches
The second step is to convert the dimensions to pixels:
Length = 11 inches x 120 = 1320
Width = 6,8 inches x 120 = 816
Area = 1320 x 816 = 1,077,120 pixels

Hello!!! Princess Sakura here ^^
Step-by-step explanation:
First we have to solve them to make it easier to compare them.
So...
[tex]-3(-2)+3=9\\3(-4)+9=-3[/tex]
Now we now that the first one is 9 and the second one is -3. So obviously the positive number has to be greater than the negative number, so....
[tex]9>-3[/tex]
Answer:
-3(-2)+3 is greater than 3(-4)+9.
Step-by-step explanation:
First, we have to solve.
1) -3(-2)+3 Solve left to right. -3(-2)=6
6+3 Add. 6+3=9
9
2) 3(-4)+9 Solve left to right. 3(-4)=-12
-12+9 Add. -12+9=-3
-3
9 is greater than 3. So, -3(-2)+3 is greater than 3(-4)+9.

If AC = 206, find the value of Then find AB and BC
Answer:
B is the midpoint. AB+BC=AC
Since B is the midpoint, lets take AB and BC to be x.
x+x = 206
2x = 206
x = 103
Therefore the value AB and BC is 103.
