You deposit $750 in an account that earns 7.5% simple interest. How much will be in the account after 5 years?
Answers
Answer:
$1,031.25 will be in the account
Answer:
$1031.25.
Step-by-step explanation:
The formula for simple interest is
I = PRT/100 so substituting:
I = 750 * 7.5 * 5 / 100
Interest I = $281.25.
Amount in account = 750 + 281.25
= $1031.25.

Equation of the line is y=-x+3
Rewritten as an inequality is y ≤ -x+3
Step-by-step explanation:
You find the slope by doing rise over run which ends up being -1/1, so just -1.
The y-intercept is 3.
Slope intercept form is y=mx+b, so y=-x+3 is the answer in slope intercept.
Then ≤ is used because the line is going down and it's shaded to the left, also the line isn't broken, it's solid which means it's equal to, so it would be less than or equal to.

Answers
Answer:
$74
Step-by-step explanation:
25*32 will be the total amount he spent at first. ($800)
He sells 22 calculators at 40$, 22*40 = 880.
He was unable to sell 3, and he had to pay 2$ per (2*3 = 6)
He had an 80 dollar profit before he returned them, (880-800).
Then he returned three for 6$ (80-6)
His end profit was 74.

solve by substitution or elimination 5x+3y=-15 -8x-2y=10
Answers
Answer:
x=0, y=-5
Step-by-step explanation:
The system is
(1) 5x+3y=-15
(2) -8x-2y=10
Let's solve it by elimination. In order to do it, you have to multiply the equations by suitable numbers in such a way that when you add the 2 equations, one of the unknowns is eliminated
Multiply (1) by 2 and (2) by 3
(1) 10x+6y=-30
(2) -24x-6y=30
Add the two equations
10x-24x+6y-6y=-30+30 ----> -14x=0---->x=0
Now replace this value in any equation, for example in (1)
6y=-30 ----> y=-30/6----> y=-5
Answer: The required solution is (x, y) = (0, -5).
Step-by-step explanation: We are given to solve the following system of equations by the method of substitution or elimination :
[tex]5x+3y=-15~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\-8x-2y=10~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)[/tex]
We will be solving the given system by substitution method.
From equation (ii), we have
[tex]-8x-2y=10\\\\\Rightarrow -4x-y=5\\\\\Rightarrow y=-4x-5~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(iii)[/tex]
Substituting the value of y from equation (iii) in equation (i), we get
[tex]5x+3(-4x-5)=-15\\\\\Rightarrow 5x-12x-15=-15\\\\\Rightarrow -7x=0\\\\\Rightarrow x=0.[/tex]
From equation (iii), we get
[tex]y=-4\times0-5=-5.[/tex]
Thus, the required solution is (x, y) = (0, -5).

A. Counterclockwise rotation 90 about the origin
Step-by-step explanation:
All we have to do is make the 270°-clockwise [90°-counterclockwise] rotation to map it exactly on q' and p'.
I am joyous to assist you anytime.
Option (A) counterclockwise rotation 90° about the origin makes the the parallel lines p and q will coincide with parallel lines p' and q' is the correct answer.
What is transformation of rotation?A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction on the coordinate plane. In both transformations the size and shape of the figure stays exactly the same.
For the given situation,
The graph shows the parallel lines p, q and p', q' in the plane.
The parallel lines p and q coincide with parallel lines p' and q' when we transformed the parallel lines by counterclockwise rotation 90° about the origin.
After this transformation of rotation, the parallel lines p and q will coincide with parallel lines p' and q'.
Hence we can conclude that option (A) counterclockwise rotation 90° about the origin makes the the parallel lines p and q will coincide with parallel lines p' and q' is the correct answer.

What is addition ?
The process of adding two or more numbers together or combining things into one group is known as addition.
The given arithmetic expression is $5.40+$8.70+$6.30.
Let's solve the given mathematical expression.
To add decimal numbers , place the decimal point in line with the specified decimal points, align the decimal numbers in accordance with their place values. If we look at the given decimals, we can see that they are like decimals because they have two digits after the decimal point. Therefore, we will arrange them in the proper sequence and perform standard addition rule.
i.e.,
5.40 + 8.70 + 6.30
We can write this as sum of :
= (5+8+6) + (0.40 + 0.70 + 0.30)
Now , solving to get the value :
= (19) + (1.40)
= $20.40

Which expression is equivalent to (f g) (5)?
f (5) times g (5)
f (5) + g (5)
5 f (5)
5 g (5)
Answers
Answer:
Option A.
Step-by-step explanation:
Expression given in the question is (f g)(5).
We know when two functions are f(x) and g(x) then (f g)(x) represents the multiplication of two functions.
(f g)(x) = f(x).[g(x)]
For x = 5
(f g)(5) = f(5).g(x)
It may be represented by the operation as
(f g)(5) = f(5) × g(x)
Therefore, option A. will be the answer.
The function (f g)(5) can be expressed as f(5) × g(5) as an equivalent expression.
Equivalent expression to (f g)(5)The equivalent expression is determined as follows;
Two given functions such as (f(5) and g (5), can be represented by the multiplication of the two functions as shown below.
(f g) (5) = (f (5) x g (5)
(f g) (5) = (f (5) x g (5)
Thus, the function (f g)(5) can be expressed as f(5) × g(5) as an equivalent expression.

Final answer:
The ratio of blue marbles to green marbles is 14:20, which simplifies to 7:10 or as a fraction, 7/10.
Explanation:
The ratio of blue marbles to green marbles from a bag containing 4 black marbles, 14 blue marbles, 8 brown marbles, and 20 green marbles is simply the number of blue marbles divided by the number of green marbles. To express this ratio, we would do the following:
Count the blue marbles: There are 14 blue marbles.
Count the green marbles: There are 20 green marbles.
Write the ratio: The ratio of blue marbles to green marbles would be 14 blue marbles to 20 green marbles.
Express as a fraction or with a colon: As a fraction, this is 14/20, which simplifies to 7/10. Or, using a colon, it is represented as 14:20, which also simplifies to 7:10.
