The value of x in the equation x = [a^2 + a^2]/[ab + 1] is [2a^2]/[ab + 1]
What are equations?Equations are mathematical expressions that are represented by the equal to or equality sign i.e =
Examples of equations are:
a + b = c
y = mx + c
Ax + By = C
y = ax^2 + bx + c
y = x
How to determine the value of x?The equation is given as
x = [a^2 + a^2]/[ab + 1]
To start with, we evaluate the like terms i.e. we add a^2 and a^2
This is represented as
a^2 + a^2 = 2a^2
Substitute 2a^2 for a^2 + a^2 in the given equation
So, we have
x = [2a^2]/[ab + 1]
The above equation cannot be further simplified
Hence, the value of x in the equation x = [a^2 + a^2]/[ab + 1] is [2a^2]/[ab + 1]

Jayme buys a painting for $179.99 for his apartment. The tax rate is 6.5%. How much did Jayme spend after tax?
Answer:
$191.69
Step-by-step explanation:
Compute ⌈x⌉ and ⌊x⌋ for the following value of x. 71.999
The floor and ceiling functions of 71.999 returns ⌈x⌉ = 71 and ⌊x⌋ = 72.
What is the Floor and Ceiling Functions?By definition, the ceiling function returns the smallest nearest integer which is greater than or equal to the specified number whereas the floor function returns the largest nearest integer which is less than or equal to a specified value.
Thus, the Floor function ⌊x⌋ of 71.999 returns 71 which is less than 71.999. Meanwhile, the ceiling function ⌈x⌉ of 71.999 returns 72 which is greater than 71.999.
Thus, we conclude that the floor and ceiling functions of 71.999 returns ⌈x⌉ = 71 and ⌊x⌋ = 72.

(30 POINTS) A construction worker is pouring concrete stairs. The first step requires 1.7 cubic feet of concrete, and the first 4 steps require a total of 17 cubic feet. If the steps follow an arithmetic series, how much concrete is required for the first 12 steps?
51 cubic feet
93.5 cubic feet
132.6 cubic feet
244.8 cubic feet
The volume of concrete required for the first 12 steps is 132.6 cubic feet
Given data
the first step requires 1.7 cubic feet of concrete
the first 4 steps require a total of 17 cubic feet
How to solve for the first 12 stepsthe first term = a = 1.7
4th step = n/2 ( 2a + ( n - 1 ) d )
d is common difference
n = number of terms
17 = 4/2 ( 2*1.7 + ( 4 - 1 ) d )
17 = 2( 3.4 + 3d )
8.5 = 3.4 + 3d

Two towns are 52 km apart. Buses travelling
between the two towns leave at the same
time but travel in opposite directions. The
bus from town A is travelling 80 km/h and
the bus from town B is travelling 70 km/h.
How long after they leave will they pass each
other? (Reminder: there are 60 minutes in an
hour!)
Step-by-step explanation:
x = number of km bus from A drives until they meet.
y = number of km bus from B drives until they meet.
x/80 is the time for the bus from A to reach the meeting point.
x/70 is the time for the bus from B to reach the meeting point.
both times must be equal, as they start at the same time.
so,
x/80 = y/70
but then we also know that together they have traveled the full 52 km to meet.
so,
x + y = 52
x = 52 - y
with that we go into the first equation :
(52 - y)/80 = y/70
(52 - y)/8 = y/7
7×(52 - y)/8 = y
7×(52 - y) = 8y
364 - 7y = 8y
364 = 15y
y = 364/15 km = 24.26666666... km
x = 52 - y = (780-364)/15 = 416/15 = 27.73333333... km
they will meet after (using bus from B)
364/15 / 70/1 = 364/1050 hours
= 182/525 hours =
= 60×182/525 = 10920/525 minutes =
= 728/35 = 104/5 = 20.8 minutes =
= 20 minutes 60×8/10 seconds =
= 20 minutes 48 seconds
control (using bus from A) :
416/15 / 80/1 = 416/1200 hours =
= 26/75 hours =
= 60×26/75 = 1560/75 minutes =

A party planner is making gift bags for an event. He has 96 pencils,
36 erasers, and 24 pencil toppers. Each bag needs to have the same number
of each object. What is the greatest number of gift bags that the party
planner can make? How many of each item are in each bag?
Considering the greatest common divisor, you obtain:
the greatest number of gift bags that the party planner can make is 12.the number of each item present in each bag is 8 pencils, 3 erasers and 2 pencil toppers.Greatest common divisorThe greatest common divisor is the largest number that exactly divides two or more numbers at the same time. That is, it is the largest number by which two or more numbers can be divided, resulting in a whole number.
A method to calculate the greatest common factor must follow the following steps:
Decompose or separate each number into prime factors.Common factors are noted.In each of the commons, the factor with the smallest exponent is chosen.Multiply the chosen factors.This caseTo find the greatest number of gift bags the party planner can make, you find the greatest common divisor.
To do this, decompose the numbers 96, 36 and 24:
96= 2⁵×336= 2²×3²24= 2³×3The common factors with the smallest exponent are: 2² and 3
So, the greatest common divisor between 96, 26 and 24 is calculated as: 2²×3= 4×3= 12
This means that the greatest number of gift bags that the party planner can make is 12.
To calculate the number of each item present in each bag, you divide the quantity of each item by the quantity of gift bags:
96 pencils÷ 12= 8 pencils36 erasers÷ 12= 3 erasers24 pencil toppers÷ 12= 2 pencil toppersFinally, the number of each item present in each bag is 8 pencils, 3 erasers and 2 pencil toppers.

A lifeguard walks around the perimeter of the lazy river ride. How far does the lifeguard walk?
The lifeguard walks around the perimeter which is 637.50 feet.
Perimeter is defined as the measure of sum all sides of a 2 dimensional figure. To calculate the perimeter we add all the individual sides of a polygon. The perimeter of a square is the sum of all four sides.
Since a triangle has three sides, the perimeter of a triangle is calculated by adding the sum of all the three sides of the triangle.
In the given figure we can see that the triangle is isosceles and the measure of the sides of the triangle are 216.75 feet , 216.75 feet and 204 feet.
Now the lifeguard walks around the perimeter of the triangular lazy-river ride.
Therefore perimeter = 216.75 +216.75 + 204 = 637.50 feet
Hence the lifeguard walks the perimeter which is 637.50 feet.

Carlos’ pay stub is shown. What is his net pay? Round to the nearest cent. Gross Pay-$1,800.00
Medicare-$26.10
Social Security (6.2%)-?
Federal Withholding Income Tax (19%)-?
By subtracting the taxes from the gross pay we can see that Carlos' net pay is $1,500.30
How to find Carlos' net pay?We know that the gross pay is $1,800, now we need to subtract the social security and taxes.
First, there is a 6.2% and 19% in taxes, adding that we get:
6.2% + 9% = 15.2%
Then we need to subtract a 15.2% of the gross pay, this will give:
P = $1,800*(1 - 15.2%/100%) = $1,800*(0.848) = $1,526.40
And now we also need to subtract the Medicare, which is $26.10, it gives:
$1,526.40 - $26.10 = $1,500.30
We conclude that Carlos' net pay is $1,500.30

x (number of years)
Step-by-step explanation:
"advised "
(a). if x = 4 (replace x with 4)
Using the formula above
V(4) = -1600(4) + 21,000
= -6400 + 21,000
= $14600
Value of the car after four years is $14600.
(b). if x = 8 (replace x with 8)
Using the formula
V(8) = -1600(8) + 21000
= -12800 + 21000
= $8200.
Value of the car after eight years is $8200.
(c). V(10) = 5000
This is the value of the car after 10 years
Check.
V(10) = -1600(10) + 21,000

What the given equation m = ((C + 200y) - 8000))/12y represents is as follows;
m is the amount of each monthly payment
C is the cost of the car
y is the length of loan in years
(C + 200y) - 8000) is the total amount she will repay
12y is the number of payments that she will make
How to interpret Compound Interest formula?
We know that the formula to get the compound interest is;
A = P(1 + r/100)ⁿ
Where;
A is Amount.
P is Principal
r is Rate of interest
n is time in years
Now, when we compare that to our formula given as;
m = ((C + 200y) - 8000))/12y
we can say that;
m is the amount of each monthly payment
C is the cost of the car
