The quantity is 25/8.
Given in words to evaluate the expression, 2 squared times 2 to the power of negative 5 and over 5 to the power of negative two.
Square of a number denotes a number to the power of 2.
The expression is : [tex]\frac{2^2\times2^{-5}}{5^{-2}}[/tex]
We have to use the law of exponents here:
[tex]a^m \times a^n = a^{m+n}[/tex]
and
[tex]\frac{a^m}{a^n} = a^{m-n}[/tex]
In the above cases, the bases should be same for the two numbers.
So [tex]2^2 \times 2^{-5} = 2^{-3}[/tex]
Also, negative exponents like [tex]a^{-m} = \frac{1}{a^m}[/tex].
Therefore, [tex]\frac{2^{-3}}{5^{-2}} = \frac{5^2}{2^3} =\bold{ \frac{25}{8} }[/tex]

The value of x will be 12°
How to calculate the angle?It should be noted that vertically opposite angles are equal.
Therefore, 4x will be equal to 48°
The value of x will be calculated thus:
4x = 48
Divide
x = 48/5
x = 12

Answer: 12
Step-by-step explanation:
vetrtical angles are equal to eachother. So to solve you would do
4x=48
then you have to get x by itself and to do so you need to divide the four by itself which will leave one. And as a rule you have to do it to the other side as well so…
4/4x=48/4
x=12
And that’s your answer

The measure of the supplement of an angle is 12 greater than twice the measure of its complement.
a. Measure of the angle = __________°
b. Measure of the supplement = __________°
a. 12 deg, b. 168 deg
We can create a systems of equations using this information, since supplement angles add up to 180 deg and complementary angles add up to 90 deg, when angle = x deg and supplement = y deg,
x + y = 180
y = 2(90 - x ) + 12
Solving:
x + 2(90 - x) + 12 = 180
-x + 180 + 12 = 180
x = 12
12 + y = 180
y = 168

The 65% markdown on $158.25 reduces the price by = $102.86
And the new amount price after 65% markdown = $158.25 - $102.86
= $55.39
Step-by-step explanation:
Given the amount
$158.25The Markdown = 65%If the Markdown on $158.25 is 65%
i.e.
65% of $158.25 = 65/100 × 158.25
= 0.65 × 158.25
= $102.86
So, the 65% markdown on $158.25 reduces the price by = $102.86
And the new amount price after 65% markdown = $158.25 - $102.86
= $55.39

Find the compound interest on Rs. 2000 for one year at the rate of '20%' per annum. If theinterest compounded quarterly.
Given:
Principal = Rs. 2000
Rate of interest = 20% p.a. compounded quarterly.
Time = 1 year
To find:
The compound interest.
Solution:
Formula for amount:
[tex]A=P\left (1+\dfrac{r}{n}\right)^{nt}[/tex]
where,
P = Principal
r = Rate of interest
t= Time
n = number of times interest compounded in an year.
Putting P=2000, r=0.2, n=4 and t=1, we get
[tex]A=2000\left (1+\dfrac{0.2}{4}\right)^{4(1)}[/tex]
[tex]A=2000\left (1.05\right)^{4}[/tex]
[tex]A=2000\left (1.21550625\right)[/tex]
[tex]A=2431.0125[/tex]
Now, the compound interest is
[tex]C.I.=A-P[/tex]
[tex]C.I.=2431.0125-2000[/tex]
[tex]C.I.=431.0125[/tex]
Therefore, the compound interest is Rs 431.0125.

In mathematics, permutation relates to the act of arranging all of the contributors of a hard and fast into a few sequence or order. In other words, if the set is already ordered, then the rearranging of its elements is called the process of permuting. diversifications occur, in extra or less prominent methods, in almost every place of arithmetic. They regularly stand up whilst one of a kind orderings on positive finite sets are considered.
what's a combination?
The mixture is a manner of selecting objects from a collection, such that (not like permutations) the order of selection does now not matter. In smaller instances, it is feasible to be counted the wide variety of combinations. combination refers back to the mixture of n things taken ok at a time with out repetition. to consult combos in which repetition is authorized, the terms k-choice or k-mixture with repetition are regularly used.

The length of parking lot in drawing will be 285 centimeters.
We are given the ratio of measurement in drawing to the measurement in real. In the ratio, 5 centimeters represents measurement in drawing and 2 meters represent drawing in real. Further, let the length of parking lot in real life be x centimeters.

Now performing cross multiplication of mentioned ratio and proportion to find the value of x.
2 × x = 5 × 114
Performing multiplication on Right Hand Side of the equation
2 × x = 570
Shifting 2 to denominator on Right Hand Side of the equation
x = 570÷2
Performing division on Right Hand Side of the equation
x = 285 centimeters.

If WXY is equilateral and WZY is
isosceles, find each missing measure.
Answer:
m∠1 = 60°
m∠2 = m∠4 = 39°
m∠3 = m∠5 = 21°
Step-by-step explanation:
ΔWXY is a equilateral angle,
Therefore, all angles of the the triangle are equal in measure.
m∠W + m∠X + m∠Y = 180°
3m∠W = 180°
m∠W = 60°
Since, ΔWZY is an isosceles triangle,
m∠3 = m∠5
m∠3 + m∠Z + m∠5 = 180°
m∠3 + 138° + m∠3 = 180°
2m∠3 = 180 - 138
m∠3 = 21°
Therefore, m∠3 = m∠5 = 21°
Since, m∠2 + m∠3 = 60°
m∠2 = 60 - 21
= 39°
Since, m∠4 + m∠5 = 60°
m∠4 = 60 - 21
= 39°
m∠1 = 60°

A common strategy to solve equations given in a rational form is to eliminate denominators.
If the equation is given in the form:
[tex]\displaystyle \frac{x}{a}=\frac{b}{c}[/tex]
We use the cross-product property to make it linear:
cx = ab
And solve it easily by dividing by c.

Apply the distributive property to create an equivalent expression.
5v+110
Answer: 5(v + 22).
Step-by-step explanation: The distributive property is a property of mathematics that says that multiplying the sum of two or more terms by another term will give the same result as multiplying each term individually by the other term and then adding the products together. Thus, we can factor the given equation and get 5(v + 22).
Find the 13th term of the arithmetic sequence -5x+8−5x+8, x+2x+2, 7x-4,
The 13th term of the given arithmetic sequence is estimated as a = 67x - 64.
What is meant by sequence to be arithmetic?In Arithmetic Progression, the difference between the two arithmetic orders is a constant value (AP). Arithmetic Sequence is another name for it.
We'd get to a few specific terms in AP, that were denoted as:
The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)The AP may also be defined using common distinctions, as shown below.
The following is the formula for determining an AP's n-th term: an = a + (n − 1) × dThe arithmetic progression sum is as follows: Sn = n/2[2a + (n − 1) × d].Common difference 'd' of an AP: d = a2 - a1 = a3 - a2 = a4 - a3 = ...... = an - an-1.Now, for the given question;
Consider the first term is 'a₁' = -5x+8
Consider the second term as 'a₂' = x+2
Then, the common difference is calculated as;
d = a₂ - a₁
d = x+2 -(-5x+8)
d = x+2 + 5x - 8
d = 6x - 6
Now, find the 13th term using the formula of nth term;
an = a + (n − 1) × d
a₁₃ = a₁ + (13 - 1) × d
Substituting the values;
a₁₃ = -5x + 3 + (13 - 1) × (6x - 6)
a₁₃ = -5x + 3 + (12) × (6x - 6)
a₁₃ = -5x + 3 + 72x - 72
a₁₃ = 67x - 64
Therefore, the value of the 13th term of an arithmetic sequence is found as a₁₃ = 67x - 64.
