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 =
= 104/5 = 20.8 minutes
correct.

Explain why it is not reasonable to say that 6.32 is less than 6.235 because 6.32 has
fewer digits after the decimal point than 6.235.( Use the process of comparing
numbers to help you with your explanation
The number of digits attached to the number is irrelevant as long as we considering the first non-identical integer. For example:
[tex]6.32215 > 6.32214 \\ since \: 5 > 4[/tex]
Additionally some numbers are written with two decimals only, implying that there an infinite amount of unnecessary zeros attached at the end. For example:
[tex]6.32 = 6.320000000000000000...[/tex]
Now a more clear approach would be to compare these two numbers after attaching these zeros.
[tex]6.3200000000... \\ 6.2350000000...[/tex]
Comparing the first three digits,
[tex]320 > 235 \\ 6.32 > 6.235[/tex]
Write the slope-intercept form equation of the line that passes through the points (1,−6) and (9,−5).
Complete the equation in the space below (do not enter "y = ").
Answer:
Step-by-step explanation:
Point slope form y-y₁ = m(x-x₁)
-5 - (-6) = m(9 - 1)
1 = m(8)
1/8 = m
y= 1/8x + b
-6 = 1/8(1) + b
b = -6.125
y = 1/8x -6.125
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.

Step-by-step explanation:
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

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.

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
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

The rate of commission for a commission of $5040 on total sales of $180700 nearest to tenth percent will be 2.8 %.
What is commission rate ?
The commission rate is the percentage or fixed payment associated with a certain amount of sale.
It is given that , Myrtle Gould's total sales last month were of $180700. And the commission she got for the sales was $5040.
Here , the sale is above the criteria to get the commission which is $50000.
The rate of commission can be calculated as follows :
Rate of commission (R) = (5040 × 100) / 180700
or
R = 504000 / 180700
or
R = 2.8 %
