Fill in the blank question.
Last month, the online price of a powered ride-on car was $250. This month, the online price is $330. What is the percent of increase in the price of the car? Round the percent to the nearest tenth if necessary.
Answers
The percentage of increase in the price of the car is 32%
What is the percentage of increase?Percentage increase means adding the given percentage of value to the original value.
To calculate this percentage increase:
= 100{( final value - initial value )/initial value}
Given that last month online price of powered ride-on car was $250
and this month this cost is $330
Initial value = $250
Final value = $330
Percentage increase = 100{ ( 330 -250 )/250} =100*0.32 = 32%
This the percentage increase in the price of the powered ride-on car is 32%

Answers
the expression that models the situation of the total cost of a diner, less a $10 coupon divided by 4 is (x - $10)÷4
Which is the correct algebraic expression?Here we have the total cost of a dinner, less a $10 coupon, divided by 4 people.
If the total cost is x, then the total cost less a $10 coupon is:
x - $10.
Now, taking the quotient (dividing the above amount by 4) we will get:
(x - $10)÷4
This is the expression that models the situation of the total cost of a dinner, less a $10 coupon divided by 4.

a) The line segment PQ has a length of √85 (approx. 9.219).
b) The coordinates of the midpoint of the line segment PQ is (4, 0.5).
What is the length of a line segment and the coordinates of its midpoint?
Herein we find a line segment whose endpoints are known: P(x, y) = (3, 5), Q(x, y) = (5, - 4), and we are asked to determine the length of the line segment and the coordinates of the midpoint as well. a) First, we determine the vector between the points P and Q by sum of vectors:
PQ = Q(x, y) - P(x, y)
PQ = (5, - 4) - (3, 5)
PQ = (2, - 9)
And its magnitude is determined by using the Pythagorean theorem:
PQ = √[2² + (- 9)²]
PQ = √85
b) The coordinates of the midpoint is found by using the following formula:
M(x, y) = 0.5 · P(x, y) + 0.5 · Q(x, y)
M(x, y) = 0.5 · (3, 5) + 0.5 · (5, - 4)
M(x, y) = (1.5, 2.5) + (2.5, - 2)

What does "speed" mean in mathematics?
Speed is what it means. the speed at which an object's location changes in any direction. The distance traveled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.Running time of cassettes
at standard speed = 1 hr
at standard speed = 4 hr
at standard speed = 4 hr
given the 1/4 part of tape is recorded at standard speed, 1/3 at long-play speed , 5/12 at super long-play speed,
so the running time of standard speed = 1/4 * 1 = 1/4
at long play speed
1/3 * 4 = 4/3 hours
and at super long-play speed,
5/12 * 7 = 35/12 hours
so, the total running time of the video
1/4 + 4/3 + 35/12 = 54/12 = [tex]4\frac{6}{12}[/tex] hours

A man borrows #760 at 4% and of the first year he pays back #270 after another year he repays #280. At the end of the third year he clears the debt completely. what is his final payment ?
Answers
His final payment will be $271.66464 at the end of the third year.
What is compound interest?The term "compound interest" refers to interest that is added back to the principal amount during each compounding period.
Compound interest is calculated using the formula
A = P(1+r )ⁿ, where
P = principal balance,
r = interest rate,
n = number of periods.
Given that a man borrows $760 at 4% and of the first year he pays back $270.
Amount owned by him at the end of the first year after repaying $270 = (1+4%)760 - 270
= 1.04×760 - 270
= $520.4
Amount owned by him at the end of the second year after repaying $280 = (1+4%)520.4 - 280
= 1.04×520.4 - 280
= 541.216 - 280
= $261.216
Let his final payment be x.
So, the amount owned by him at the end of the third year will be 0.
⇒ (1+4%)261.216 - x = 0
⇒ 1.04×261.216 - x = 0
⇒ 271.66464 = x
Therefore, his final payment will be $271.66464.

The equation of the line for the point (-1, 2) is [tex]y=x+3[/tex]
The slope of a line is the ratio of how much y increases when x increases by a certain amount.The graph of the linear equation y = mx + c is a straight line with slope m and y-intercepts m and c. This form of linear equation is called the slope intercept, and the values of m and c are real numbers. The slope m represents the slope of the straight line. The y-intercept b of the line represents the y-coordinate of the point where the line graph intersects the y-axis.The equation of a line whose slope is 'm' and which passes through a point [tex](x_1,y_1)[/tex] is found using the point slope form which is given by [tex]y-y_1=m(x-x_1)[/tex] ..(1)It is given that line is parallel to the line y = x + 4 . ....(2)

Answers
Answer: Aiza have left from her lifeguarding job = $ 700
Step-by-step explanation:
Given that,
Aiza made $55 a day lifeguarding in the summer.
She worked six days a week for five weeks.
For two weeks of the summer she went on vacation.
She spent approximately $68 a day each for two weeks.
Aiza earning per day = $55
Aiza worked for six days in a week.
Aiza worked for five weeks.
Total earning for weeks
= $ 55(6)
= $ 330 / week
Total earning for 5 weeks
= $ 330(5)
= $ 1650
Aiza spent per day for vacation = $ 68
Aiza was an vacation for two weeks.
Total expenditure for two weeks,
Number of days in each week = 7 days
= 2(7)($ 68)
= $ 952
Aiza have left with = Total earning - Total expenditure
= $ 1650 - $ 952

Solve the system of equations using elimination: -6x - 6y = −42 and -x + 2y = 8.
Answers
The solution of given system of equations is 6 and 7.
To solve the system of equations using elimination, we will equate any one variable. In this case, we will be equating variable y.
Rewriting the equations -
-6x - 6y = −42 : equation 1
-x + 2y = 8 : equation 2
Multiplying equation 2 with 3
-3x + 6y = 24 : equation 3
Adding equation 1 and equation 3 to solve the given system of equations
-6x - 6y = −42
3x + 6y = 24
We get the answer :
-3x = -18
Negative sign will be cancelled and performing division
x = 6
Keep the value of x in equation 2
-6 + 2y = 8
2y = 8 + 6
2y = 14
y = 14 ÷ 2
y = 7
Therefore, the value of x and y is 6 and 7 in given system of equations.

Answers
The formula 3x-y=5 is a linear function.
We must first examine the slope of the original function in order to determine the equation of parallel lines. We are also given the other function's intercept in this issue.
The function's slope-intercept form is y=3x-5.
In order to locate the parallel line that corresponds to the point (0,-7)
Parallel lines are those that share the same slope but have different y-intercepts, as you may have seen.
As a result, we must put in the point to solve for the y-intercept.
Thus,
y = 3x + b
-7 = 3(0) + b
-7 = b
b = -7
Thus the equation of a parallel line is y = 3x - 7

Mathematical Induction : For each and every natural number n, mathematical induction is a method of demonstrating a statement, theorem, or formula that is presumed to be true.
It is given that the statement is true for n = k
Explanation:
According to the principle of Mathematical Induction,
Let d(n) be a statement involving Natural Number n such that
d(1) is true
d(m) is true
d(m+1) is true
So , the statement d(n) is true for all the n natural numbers.
According to the second principle of Mathematical Induction
Let d(n) be a statement involving Natural number n such that
d(1) is true
d(m) is true when d(n) is true for all n where 1 ≤ n ≤m .
Then the statement d(n) is true for all the values of n ( natural number)
Therefore , we have proved below that d( k+1) is only true when d(k) is true , also d(1) should also be true using Mathematical Induction.
