3x + 4y = 25 is an example of a line that is parallel to the supplied line.
What is equation ?Equations are mathematical expressions that have two algebraic expression on either side of an equals (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left hand side = right hand side) is a fundamental mathematical formula. For an unknown quantity represented by an unknown variable, equations can be solved to determine its value. It is clear that a statement is not an equation if there is no "equal to" sign in it. The phrase will be regarded as an expression.
Given that : line that is parallel to the line 3x + 4y = 32 and contains

A bottle of maple syrup in Wayne’s freezer needs to be warmed for breakfast. Sitting on the kitchen counter, the bottle temperature will go up a steady 9.6° C every hour. If the bottle temperature begins at the freezer temperature of –16° C, how many hours will it take to reach 20° C?
Change in temperature: (20 – (–16)) = 20 + 16 = 36
It will take the bottle of maple syrup 3 hours 45 minutes to reach 20° C from –16° C.
How to get the temperature changegiven data
the bottle temperature will go up a steady 9.6° C every hour
freezer temperature = –16° C
final temperature = 20° C
The temperature rise from –16° C to 20° C
from –16° C to 0° C = 16° C
from 0° C to 20° C = 20° C
adding both increments gives = 20 + 16 = 36° C
if every hour we have 9.6° C then how many hours will give 36° C
1 hour = 9.6° C
? hour = 36° C
we cross multiply to have
= 36 * 1 / 9.6
= 3.75
This is 3 hours then a fraction of some minutes, the fraction is gotten by
0.75 * 60 = 45
Therefore the time to reach 20° C is 3 hours 45 minutes

The side x of the rectangle is 36.0 cm
How to find side of a rectangle?A rectangle is a quadrilateral with opposite sides equal to each other and opposite sides parallel to each other.
All four angles of a rectangle are right angles.
The diagonal of a rectangle are equal in length to each other and they bisect each other at there point of intersection.
Therefore,
∠ COD = 48°
∠OCD = ∠ODC = 132 / 2 = 66°
Using sin law
OD / sin 66 = 16 / sin 48
OD sin 48 = 16 sin 66
OD = 16 sin 66 / sin 48
OD = 14.6167273223 / 0.74314482547
OD = 19.6687105931
OD = 19.7 cm
∠AOD = 180 - 48
∠AOD = 132°
∠OAD = ∠ODA = 48 / 2 = 24°
Hence, using sine law let's find x
19.7 / sin 24 = x / sin 132
x sin 24 = 19.7 sin 132
x = 19.7 sin 132 / sin 24
x = 14.6399530619 / 0.40673664307
x = 35.9935605802

how many nonzero complex numbers zz have the property that 0, z,0,z, and z^3,z 3 , when represented by points in the complex plane, are the three distinct vertices of an equilateral triangle?
Consequently, there exist four numbers z:

-√3/2 ± I 1/2
The three unique vertices of an equilateral triangle are 0, z, and z3: (z^3=0)= e ^iπ/3(z -0 ) ⇔ z^3=e^(±iπ/3)z
=(z^2-e^±iπ/3)z=0⟺z=0

How many smaller squares can you fit inside a larger square with side length of 31 units?

62 smaller squares
31 smaller squares
29,791 smaller squares
The number of smaller squares that can fit inside a larger square with a side length of 31 units is A. 961 smaller squares if the larger square is a plane.
What is a side length?A side length is one part of the length of an object.
Determining the number of smaller squares in a larger square depends on if the square is an enclosure or a plane.
If the square object is an enclosure, then it has three dimensions, length, width, and height, which are squared. In that case, the number of smaller squares will be 29,791.
But if the square object is a plane with two dimensions, the number of smaller squares is 961.
Side length = 31 units
Area of a square plane = 961 unit² (31 x 31)
Volume of a square enclosure = 29,791 unit³ (31 x 31 x 31)
Thus, the number of smaller squares depends on the dimensions of the larger square.

A pair of shoes usually sells for $68 if the shoes are 40% off and sales tax is 6% what is the total price of the shoes including tax
Usual selling price of a pair of shoes is $68 with discount 40% and sales tax 6% then total price of shoes including tax is equal to $43.248.
As given in the question,
Given that:
Usual selling price of shoes = $68
Discount on shoes =40%
Discounts an amount or percentage from something that they are selling, they take the amount or percentage off the usual price.
so, remove 40% from the price and you have left 60%
reduced price = 60% of $68
=60/100 * 68 = $40.8
Sales tax is 6% of reduced price= 6% of $40.8
=$2.448 upto 3 decimal digits
Now , price including tax =$40.8+$2.448 =$43.248
Hence, total price including tax= $43.248
Therefore, usual selling price of a pair of shoes is $68 with discount 40% and sales tax 6% then total price of shoes including tax is equal to $43.248.

Based on the equation of the line that is parallel to the first line, the equation of the line in slope-intercept form is y = 3/4x - 6³/₄
How to write the equation?First, find the slope of 3x + 4y = 7:
( 3x + 4y = 7) x 1/4
3/4x + y = 7/4
The slope is therefore 3/4x.
Lines that are parallel to each other have the same slope. You can therefore use this slope to find the formula of the other line by first solving for the y-intercept:
y = Slope(x) + y-intercept
-9 = 3/4(-3) + y-intercept

the population of a community is known to increase at a rate proportional to the number of people present at time t. if an initial population p0 has doubled in 9 years, how long will it take to triple?
Since the population increases at a rate proportional to the current number of people, the population will be three times of its initial population after 14.27 years.
The population of a community increases at a rate proportional to the number of people present at time t, means:
dP/dt = kP
where k is a constant.
Rearrange it:
(1/P) dP = k dt
Take the integral:
∫ (1/P) dP = ∫ k dt
ln P = kt + C, where C is a constant
Substitute t = 0, from the problem, it is known that P(t = 0) = P₀
Hence,
P(t) = P₀. e^(kt)
The population doubles after 9 years, means if we substitute t = 9
P(9) = P₀. e^(9k)
2P₀ = P₀. e^(9k)
2 = e^(9k)
Take the natural logarithmic:
ln 2 = 9k
k = (ln 2)/9 = 0.077
When the population grows to triple, it means P(t) = 3P₀
3P₀ = P₀. e^(kt)
ln 3 = kt
ln 3 = 0.077 t
t = (ln 3)/0.077 = 14.27 years.
Hence, the population will be three times of its initial population after 14.27 years.

-3 + 5 = 2. On a graph, you always move right along the x axis for positive numbers, and left for negative numbers.
a certain town is served by two hospitals. in the larger hospital about 45 babies are born each day, and in the smaller hospital about 15 babies are born each day. as you know, about 50% of all babies are boys. however, the exact percentage varies from day to day. sometimes it may be higher than 50%, sometimes lower.
the more compact hospital. The Law of Large Numbers, which makes intuitive sense, states that when there are more observations, the experimental average tends to approach the true proportion. Large hospitals have more observations, therefore their results are less likely to deviate from 50% or have a wide range of results.
What is the True proportion?An equation that states that two ratios are equal is a genuine proportion. You can utilise information about one ratio in a proportion to determine values in the other equal ratio.
The sample proportion, p′ = 0.842, which is the point estimate of the population proportion, must be determined in order to calculate the confidence interval. Given that CL = 0.95 is the requested confidence level, = 1 - CL = 1 - 0.95 = 0.05 ( 2) ( 2) follows..
