If each of the 4 sloping side ahs length 10 cm
This implies they have length 40 cm altogether
To find the base length, simply subract the 40 cm from the total length of 68cm
68 - 40 = 28
each base length = 28/4 = 7cm
Area of the square base is = l x l = 7 x 7 = 49 cm²

A factory produce 11,650 gallon of lemonade 4,950,fewer gallons of ice tea than lemonade
Answers
Factories produce a total of 21550 gallons in a calendar year.
The gallon is used as a unit of volume in both imperial and US customary measurements.
Eight pints make up a gallon, which is a unit of measurement for liquids. It is equivalent to roughly 4.546 litres in Britain. It is roughly equivalent to 3.785 litres in America.
Lemonade, it has been stated, equals 11,650 gallons.
Lemonade = 4,950 fewer than ice tea.
Ice tea: 3,500 fewer than Root beer.
Using the formula Ice tea = 11,650 - 4,950
6700 gallons of iced tea
Root beer = 6700 - 3,500
3200 gallons equals root beer.
Total manufacturing output for a year is equal to 11,650 + 6700 + 3200
Thus, 21550 gallons are produced in total by factories each year.

June has 72 gallons of punch for a party. June carries the punch in two different full coolers. The bigger cooler is five times as large as the smaller cooler. How many gallons can each cooler hold?
Answers
If June has 72 gallons of punch for a party and June carries the punch in two different full coolers. The bigger cooler is five times as large as the smaller cooler, then the capacity of smaller cooler is 12 gallons and the capacity of bigger cooler is 60 gallons
The bigger cooler is five times as large as the smaller cooler
Consider the capacity of smaller cooler as x
The capacity of bigger cooler=5x
June has 72 gallons of punch for a party
Then the linear equation will be
x+5x=72
6x=72
x=12
Then the capacity of bigger cooler=5x
=5×12
=60
Hence, if June has 72 gallons of punch for a party and June carries the punch in two different full coolers. The bigger cooler is five times as large as the smaller cooler, then the capacity of smaller cooler is 12 gallons and the capacity of bigger cooler is 60 gallons

Answers
The slope of the line is 60 and speed of the bus is 60 miles per hour
The slope of the line is the measure of the steepness. In other words the slope of the line is the change in y coordinate with respect to the change in x coordinate.
Here the points are
(1,60) and (2,120)
The slope of the line m =[tex]\frac{y_{2}-y_{1} }{x_2-x_1}[/tex]
Where m is the slope of the line
[tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the coordinates of the points
Substitute the values in the equation
The slope of the line m = [tex]\frac{120-60}{2-1}[/tex]
= 60
The speed = Distance / Time
Take one point (2,120)
The distance = 120 miles
Time = 2 hours
The speed = 120/2
= 60 miles per hour
Hence, the slope of the line is 60 and speed of the bus is 60 miles per hour.

You want to buy a 28,000 car. You can make a 10% down payment, and will finance the balance with a 2% interest for 48 months. What will your monthly payment be
Answers
The monthly payment when you want to buy a 28,000 car is $567.
How to calculate the value?It should be noted that when the 10% down payment is made, the amount left will be:
= $28000 - (10% × $28000)
= $28000 - $2800
= $25200
The interest will be:
= PRT / 100
P = $25200
R = 2%
T = 48 months = 4 years
Interest = (25200 × 2 × 4)/100
= $2016
Total amount to be paid:
= $25200 + $2016
= $27216
The monthly payment will be:
= Amount / 48 months
= $27216 / 48
= $567
The monthly payment is $567.

Step-by-step explanation:
it is just a matter of definition that can be easily looked up.
the domain is the interval or set of all valid x values.
while the range is the interval or set of all valid y (function result) values.
so, the domain here is every value of x used in this function.
e.g. does x = -6 have a functional (y) value in the curve ?
no, it does not.
x = - 4 ? no.
x = -2 ? no.
x = -1 ? ah, yes, this is just the left-most point of the curve.
and then all x values further to the right of -1 are covered. as the arrows indicate : into all eternity ("to infinity and beyond !")
so, the domain is [-1, +infinity).
and you need to use B.
please note, the round bracket indicates that that ends of the interval is not included or undefined (after all, infinity is not a number we can work with, it is basically undefined and only represents a principle).
for the range this is tricky, as the graph does not really show us the limit. it could be y = -1 or 0 down to y = -9 or -10.

What is half-life?The amount of time needed for a quantity to decrease to half of its original value is referred to as its half-life.
In nuclear physics, this word is often used to define the rate at which unstable atoms undergo radioactive decay or the amount of time stable atoms are able to persist.
Additionally, the phrase may be used in a broader sense to define any form of exponential decline.
Generally,
A = A0e^{-kt}
Therefore
A(t) = A0e^{[ln(0.5) / 7310 t}, t in years
0.20 = e^{ln(0.5) / 7310 ]t}
Solve for t.
ln(0.20) = [ln(0.5) / 7310 ]t

Write an equation of a parabola that passes through the points (-3,-5) , (-1,3) , and (0,4)
Answers
Hence the equation of the parabola is y = -x² + 4
In mathematics, a parabola is a roughly U-shaped, mirror-symmetrical planar curve. The same curves can be defined by a number of seemingly unrelated mathematical definitions, which all correspond to it.
A line and a point (the focus) are two components of one definition of a parabola (the directrix). There is less emphasis on the directrix. The parabola is the location of points in that plane that are equally spaced apart from the directrix and the focus. Another definition of a parabola is a right circular conical surface intersected by a plane parallel to another plane tangential to the conical surface, resulting in a conic section.The general equation of a parabola is given by y = ax² + bx+ c
The parabola passes through (-3,-5) , (-1,3) , and (0,4).
Now substituting the values in the parabola we get :
-5 = a(-3)² + b(-3)+ c
or , -5 = 9a -3b + c
again:
3 = a(-1)² + b(-1)+ c
or, 3 = a -b + c
again
4 = a(0)² + b(0)+ c
or, c =4
Solving the equation we get :
9a - 3b = -9 and a-b = -1
a= -1 and b = 0
Hence the equation of the parabola is
y = -x² + 4

Mrs. Byers rents a water trampoline for her son's birthday party. The delivery fee for the trampoline is $75, plus a rental fee of $8 per hour. She wants to spend less than $125 on the trampoline. Find h, the number of hours Mrs. Byers could rent the trampoline?
Answers
Answer:
h= 6
Step-by-step explanation:
To find out the value of h, start by forming an equation for the cost of renting a trampoline:
Cost of renting= $(75 +8t), where t is the rental duration.
When the cost is $125,
75 +8t= 125
Subtract 75 from both sides:
8t= 125 -75
8t= 50
Divide both sides by 8:
t= 50 ÷8
t= 6.25
Since she wants to spend less than $125, let's round the value down to the nearest hour.
∴ h= 6
Thus, she could rent it for 6 hours.
Let's check!
Total cost of renting for 6 hours
= 6(8) +75
= $123
Total cost of renting for 7 hours
= 7(8) +75
= $131
Hence, 6 hours is indeed the maximum number of hours she can rent the trampoline for, such that the total cost is less than $125.
