Answer:
Im not too sure because I haven't done this in a while but, I think the answer is 60cm, don't come at me if its wrong plssss
Step-by-step explanation:
if u divide it along the far left, closer to 12cm, u would have 2 rectangles. they would Both be close and If u added up 12cm and 12cm that would give you 24cm, and if you go to the other rectangle it would be 18 cm plus 18cm that would be 36cm. u do not multiply since it is perimeter and not area. Hope it helped!
Answer:
60 cm
Step-by-step explanation:
18+18+12+12
30+30
60
the 4 unknown sides we know that the 2 lengths equal 18 cm because both of them together are the same length as the base and the 2 widths add up to be 12 cm since it is the same size as the 12 cm width when added together if that makes sense

What is vertical asymptote?
A vertical asymptote is a line that appears to correspond with a function's graph but never really touches the curve. When graphing a function, the vertical asymptote of the function is crucial.
The curve is neither touched or crossed by a vertical asymptote, which is a vertical line along which the function becomes unbounded (either y tends to or -). K is NOT present in the domain of the function if x = k is the vertical asymptote of a function y = f(x). Any quantity of vertical asymptotes is possible for a function. i.e., it may have 0 vertical asymptote, 1, 2,..., or a limitless amount. If the y-axis represents the vertical asymptote, we often do not portray it by a dotted line. Instead, we represent a vertical asymptote by a vertical dotted line.

The difference in b-tree and b +tree, b -tree is a self balancing tree data structure that maintains sorted data and b +tree is a modified version of b -tree.
b -tree is used to sort the data with various pieces facilities such as insertion ,deletion and search etc whereas b +tree is a modified version of b -tree providing all the functions smoothly and quickly .
In b -tree, both internal nodes and leaf nodes are used to store records and keys whereas in b +tree keys are stored in internal nodes whereas records are storing leaf nodes
In b +tree, no duplication is allowed but in b +tree duplication may occur
A b +tree usually preferred as an access structure to a data file as as the height of the tree remains balanced and less as compared to b -tree . We can assess the data stored in b +tree sequentially as well as directly . keys are used for indexing . Faster search queries as the data is stored only on a leaf nodes.

What is AOD?
AOD is nothing but application of differentiation. It implies scopes where we can use differentiation to make our calculations easy.
Here, given
Length and breadth = 2,3 foot
Let us consider length of side of square = x
So, after cutting squares left sides of rectangular sheet = 2-2x , 3-2x
So, volume = (2-2x)*(3-2x)*x

A vehicle uses 1\frac{1}{8} gallons of gasoline to travel 13\frac{1}{2} miles. Create a rate to represent the miles the vehicle can travel per gallon of gasoline.
The vehicle can travel 12 miles per gallon of gasoline.
What is the Mixed fraction ?
A mixed fraction is one that is represented by both its remainder and quotient. Consequently, a mixed fraction is created by combining a whole number and a proper fraction.
What is the Rate ?
A rate is the comparison of two comparable amounts expressed in different units. If the ratio's denominator is written as a single unit of one of these quantities, and if it is assumed that this quantity can be modified systematically (i.e., is an independent variable), then the numerator of the ratio indicates the comparable rate of change in the other (dependent) variable.
The vehicle travels 13\frac{1}{2} by using 1\frac{1}{8} gallons of gasoline.
since the units are in mixed fraction, we can simplify it to simple fraction,
distance travelled= 13\frac{1}{2} = [(13 × 2) + 1] / 2 = 27/2 miles.
gasoline used= 1\frac{1}{8} = [(1×8)+1] /8 = 9/8 gallons.
∴ Miles per gallon of gasoline = distance travelled ÷ gasoline used
= 27/2 miles ÷ 9/8 gallons
= 12 miles per gallon of gasoline.
Hence, The rate of miles per gallon of gasoline is 12 miles/gallon of gasoline.

The probability that the number 6 will appear between 150 and 200 times inclusively is 0.926.
In the given question, one thousand independent rolls of a fair die will be made.
We have to compute an approximation to the probability that the number 6 will appear between 150 and 200 times inclusively.
Let n=1000 are independent trails.
The probability of success is constant, p=1/6
The probability of success is not constant,
q=1-1/6 = 5/6
let X be the number of times the die shows a 6.
μ = np
μ = 1000*1/6
μ = 166.7
σ=√npq
σ=√1000*1/6*5/6
σ=√5000/36
σ=11.785
Now we used the correlation continuity for finding the probability that number 6 will appear between 150 and 200 times is
P(150≤X≤200)=P(X≤200)-P(X<150)
P(150≤X≤200)=P(Z≤(200+0.5-166.7)/11.785)-P(Z≤(150-0.5-166.7)/11.785)
P(150≤X≤200)=P(Z≤2.87)-P(Z≤-1.46)

Type the correct answer in each box. Use numerals instead of words for numbers. If necessary, use / for the fraction bar(s). The amount of time it takes a water pump to empty a tank varies directly as the capacity of the tank. If it takes a water pump 2. 5 hours to empty a tank containing 60,000 gallons of water, how long does it take the same pump to empty a tank containing 108,000 gallons of water? it will take hours to empty the second tank.
An equation is formed when two equal expressions. The time the same pump will take to empty a tank containing 108,000 gallons of water is 4.5 hours.
What is an equation?When two equal expressions are added together with the aid of the equal sign "=," an equation is created.
Given that the time it takes a water pump to empty a tank directly correlates with the tank's capacity. Consequently, the relationship can be expressed as,
V ∝ T
V = kT
Substituting the volume and time in the equation,
60,000 gallons = 2.5 hours × k
Solving the equation for k,
k = 60,000 gallons / 2.5 hours
k = 24,000 gallons per hour
Now, the equation for the relationship can be written as,
V = 24,000 gallons per hour × T
Now, the time the same pump will take to empty a tank containing 108,000 gallons of water is,
V = 24,000 gallons per hour × T
108,000 gallons = 24,000 gallons per hour × T
108,000 gallons / 24,000 gallons per hour = T
T = 4.5 hours
Hence, the time the same pump will take to empty a tank containing 108,000 gallons of water is 4.5 hours.

What are trigonometric identities?Trigonometric identities are equations that involve trigonometric functions that are valid for all values of the input variable.
The possible value of sin(u) obtained from a similar question posted online is; sin(u) = 5/13
Both u and v are in quadrant II
The trigonometric identity of the addition formula for the sine of the sum of two angles, indicates;
sin(u + v) = sin(u)·cos(v) + sin(v)·cos(u)
sin(u) = 5/13
cos(v) = -4/5
sin(v) = √(1 - (cos(v))²)
Therefore;
sin(v) = √(1 - (-4/5)²) = 3/5
cos(u) = √(1 - (sin(v))²)
Therefore;
cos(u) = √(1 - (5/13)²) = 12/13
