Answer:
Step-by-step explanation:
Lin after 1 year has 300+2*300/100=300+6=306 $
after 2 years has 306+2*306/100=306+6.12=312.12$
150-15*150/100=150-22.5=127.5 $ the price for the bicycle
The value after 20 years is $ 723.514
Solution:
Formula for Amount compounded annually is as follows:
Where,
"A" is the total amount
"p" is the principal sum
"r" is the rate of interest
"n" is the number of years
From given question,
p = $ 300
r = 4.5 %
n = 20 years
Substituting the values we get,
Thus value after 20 years is $ 723.514
PART 2)
2. Given data
Cost of bicycle = $150
Depreciation = 15%
Firstly let us calculate 15% of $150
(15/100)*150 =0.15*150
= $22.5
Since the value depreciated
We will minus the the depression from the initial amount
New amount = 150-22.5=
$127.5
25b +15b combine like terms
Answer:
40b
Step-by-step explanation:
25 + 15 = 40
Answer:
40b
Step-by-step explanation:
We are given the expression:
25b+15b
and asked to simplify.
To simplify, we must combine like terms. Let's analyze the terms.
25b ⇒ has a variable "b"
15b ⇒ also has a variable "b"
The like terms in this expression are the terms with a variable, b.
To combine like terms, add the coefficients and leave a b on the end.
(25+15)*b
(40)*b
40b
The expression 25b+15b simplified is 40b.

Answer: multiplied together or divided, the answer is positive. If two negative numbers are multiplied together or divided, the answer is positive.

What is the Subtraction operation?Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
In mathematics, adding a negative number and a positive number involves combining two quantities with opposite signs. When we add a negative number and a positive number, we can think of it as "subtracting the absolute value of the negative number from the positive number."
For example, if we have -3 + 5, we can rewrite it as 5 - 3, which equals 2. In this case, we are subtracting the absolute value of the negative number (3) from the positive number (5).
Similarly, if we have -7 + 2, we can rewrite it as 2 - 7, which equals -5. In this case, we are subtracting the absolute value of the negative number (7) from the positive number (2), but since the negative number has a larger absolute value, the result is negative.
So, the result of adding a negative number and a positive number will depend on the magnitude of the two numbers and which one is larger.

Write the ratio 7.5 : 2.5 in the form n : 1
Answer:
3 : 1
Step-by-step explanation:
[tex] \huge7.5 : 2.5 = \frac{7.5}{2.5} = \frac{3}{1} = 3 : 1 [/tex]
The equivalent ratio to 7.5 : 2.5 is given by dividing both elements by 2.5, the ratio is: 3 : 1
How to rewrite the ratio?Remember that in a ratio A : B we can always multiply or divide both numbers by the same number, and the ratio does not change.
So, for the ratio:
7.5 : 2.5
To be in the form of:
n : 1
We can just divide both elements by 2.5, so we get:
7.5/2.5 = 3
2.5/2.5 = 1
Then we conclude that:
7.5 : 2.5 is equivalent to 3 : 1

Peter withdrew 1000 dollars from his bank account today. He uses 500 to fix his car. Then, he divided the money into 5 equal parts and gave away 4 parts and kept 1 part for himself. Finally, he took his wife to the restaurant and spent 60 dollars on meals. Write a numerical expression to represent this situation and then find how much money Peter has now?
Answer:
ok he has $40 left
Step-by-step explanation:
1000-500 = 500
500 - 400 = 100
100-60 = 40
Answer:
Money with Peter = $ 40
Step-by-step explanation:
Let 'x' be the money left with Peter
Money left with Peter after fixing his car = 1000 - 500 = 500
500 is divided into 5 equal parts and 4 parts he gave away. 500 - 400 = 100
x = (1000 - 500) - 400 - 60
= 500 - 400 - 60
= 100 - 60
x =$ 40

What’s the measure of X in this short answers are fine
Answer:
28 = x
Step-by-step explanation:
62 = angle BAC since they are vertical angles
angle ABC is a right angle since KL is perpendicular to FG
Adding the angles in triangle ABC
BAC + ABC + BCA = 180
62 + 90 + BCA = 180
152 + BCA = 180
BCA = 180-152
BCA = 28
BCA = x since they are vertical angles
28 = x
How do I solve for y in this equation? 3xy-28=15x
Answer:
x = 28/(3y -15)
Step-by-step explanation:
Put the x-terms on the same side of the equal sign and everything else on the other side. Divide by the coefficient of x.
3xy -28 = 15x . . . . . . given
-28 = 15x -3xy . . . . . subtract 3xy
-28 = x(15 -3y) . . . . . factor out x
-28/(15 -3y) = x . . . . . . divide by the coefficient of x
We prefer to have a positive sign where possible, so we can multiply this by -1/-1 to get ...
x = 28/(3y -15)

Question is in the image
=====================================================
Explanation:
The blue parent function has a positive coefficient of 1. The purple g(x) function is a reflection of f(x) over the x axis, so everything is now negative. The coefficient must be negative as well.
But the answer is simply not g(x) = -x^2 because plugging x = 3 does not lead to y = -6 as the point (3,-6) shows.
Let's say the coefficient is k for now. So we have y = kx^2
Plug in x = 3 and y = -6. Solve for k
y = kx^2
-6 = k(3)^2
-6 = k*9
9k = -6
k = -6/9
k = -2/3
So we update y = kx^2 into y = (-2/3)x^2
Meaning that g(x) = (-2/3)x^2 is the equation of the purple curve.
Plug x = 3 into g(x) to find that
g(x) = (-2/3)x^2
g(3) = (-2/3)(3)^2
g(3) = (-2/3)(9)
g(3) = -6
which is the output we want, so this confirms we have the correct coefficient.
Answer:
y=(-2/3)x^2
