The following equations are equivalent:
2 + x = 5
x + 1 = 4
Negative 5 + x = negative 2
This is because, in each equation, x is the same variable, and it has the same value on both sides of the equation.
In the first equation, x is equal to 3.
In the second equation, x is equal to 3
In the third equation, x is equal to -3
Note that the equation 9 + x = 6 and x + (negative 4) = 7 are not equivalent as these equations have different values for x.
Find the two missing numbers in the following sequence: 1, 8, ?, 16, 17, 24, 25, 32, 33, ?
Answer:
7 and 40
Step-by-step explanation:
for you to get the next number you have to add 7 to that number...then add 1 to the number you have gotten then continue like that
eg: to get 8 you had to add 7 to 1 now to get the next number add 1 to 8 to get 9 then add 7 to 9 to get 16 then continue like that

Upon solving the decimals, The expression which is equivalent to 0.125 are -12.5 ÷ 10²⇒ 0.125 and 1,250 ÷ 10⁴ ⇒ 0.125.
A decimal is a number that is divided into two parts: a whole and a fraction. Between integers, decimal numbers are used to express the numerical value of complete and partially whole quantities.
Decimal fractions and recurring (repeating or non-terminating, like) decimals are the three different sorts of decimals (a.k.a. converting a decimal into a fraction whose denominator is a power of ten).
1.25 ÷ 10 ⇒ 0.125
Upon solving the decimals,
12.5 ÷ 10² ⇒ 0.125
0.125 ÷ 100 ⇒ 0.00125
1,250 ÷ 10⁴ ⇒ 0.125
12.5 ÷ 1 ⇒ 12.5

If sum of 5 numbers in AP is 40 then find the middle term
Answer:
8
Step-by-step explanation:
Let the AP numbers be: ( a - 3d ), ( a - d ), a, ( a + d ), ( a + 3d )
We are given that sum of all these numbers is 40.
⇒ a - 3d + a - d + a + a + d + a + 3d = 40
⇒ 5a + 4d - 4d = 40
⇒ 5a = 40
⇒ a = 40 / 5 = 8
We know that the middle term of the five numbers given is 'a'.
As a result, the given AP's middle term is 8.

(a) What is the minimum UGPA that
would still place a student in the top
10% of UGPAS?
(b) Between what two values does the
middle 50% of the UGPAS lie?
Mean=3.24
Std.=0.17
a) The Corresponding minimum UGPA = 3.70
b) The range of middle 50% values will be: (3.28, 3.52).
What is the z-score?
A z-score (also known as a standard score) is a measure of how many standard deviations an individual data point is from the mean of a distribution. A z-score is calculated by subtracting the population mean from an individual data point, and then dividing that number by the population standard deviation.
a) z score corresponding to top 5% area = 1.645
Hence,
Corresponding minimum UGPA = 3.40 + 1.645*0.18 = 3.70
b) z score corresponding to middle 50% area = -0.67, 0.67
Hence,
The range of middle 50% values will be:
(3.40 - 0.67*0.18, 3.40 + 0.67*0.18)
(3.28, 3.52)
Hence,
a) The Corresponding minimum UGPA = 3.70
b) The range of middle 50% values will be: (3.28, 3.52).

Evaluate the following integral: ∫20(45t3−34t2+25t)dt
The integral[tex]∫20(45t^3-34t^2+25t)dt[/tex] can be evaluated by using the power rule of integration, which states that the derivative of x^n is [tex]nx^(n-1)[/tex]. This rule can be applied to each term of the integral separately.
The first step is to integrate [tex]∫20(45t^3-34t^2+25t)dt[/tex] with respect to t. By using the power rule, we can find the antiderivative of each term inside the parentheses:
[tex]∫45t^3 dt = (45/4)t^4 + C[/tex] (the antiderivative of 45t^3 is (45/4)t∧4)
[tex]∫34t^2 dt = (34/3)t^3 + C[/tex] (the antiderivative of 34t^2 is (34/3)t∧3)
[tex]∫25t dt = (25/2)t^2 + C[/tex] (the antiderivative of 25t is (25/2)t∧2)
Now, we can substitute these results back into the original integral:
[tex]20(∫45t^3 dt - ∫34t^2 dt + ∫25t dt) = 20((45/4)t^4 + (34/3)t^3 + (25/2)t^2) + C= 20(15t^4-11t^3+25t^2) + C[/tex]
So, the evaluated integral for [tex]∫20(45t^3-34t^2+25t)dt[/tex] is [tex]20(15t^4-11t^3+25t^2) + C.[/tex]

Angles in parallel lines are formed when two parallel lines intersect with another line known as a transversal. So here ∠y is 40° and ∠z is 140°.
What are the angles over parallel lines?Parallel lines form a pair of angles when cut by a transversal. As a result, corresponding angles are equal, as are alternate interior angles, alternate exterior angles, vertical angles, and the sum of interior angles on the same side of the transversal.We know that sum of angles over a straight line is 180°
So here ∠x + 140° = 180°
So ∠x = 180 - 140
Therefore ∠x = 40°
So in this figure ∠x = ∠y , Since they are corresponding angles are equal.
Therefore ∠y = 40°
So ∠z will be 140° . Since ∠y = 40° its opposite angle will also be 40°.
So ∠z + 40° = 180°
Therefore ∠z = 140°
So the angles ∠y = 40° and ∠z = 140°.

A % is a quantity or ratio that, in mathematics, represents a portion of one hundred. It's frequently represented by the sign "%" or just "percent" or "pct." For instance, 35% is equal to the fraction 0.35 or the decimal 0.35.
The value of the number out of 100 is the proportion of the number. For instance, there are 26 females and 24 boys in a class. As a result, 52 out of 100 students in the class are females, or 52% of the class.
The Latin word "per centum," which meaning "by the hundred," was the source of the English word "percentage." Percentages.

What are the indices for the directions indicated by the two vectors in the following sketch?
The indices for the directions are indicated by the two vectors in the following sketch - [1 0 0] and [ 2 0 3].
Miller Indices of Direction Vector:
The Miller indices of direction are rationalized components of the direction vectors taken in all crystallographic directions. They are indicated by [[u v w ]]. They are always defined as the smallest integers, so if they occur in fractional or decimal form, we need to convert them into the smallest integral value by algebraic manipulation.
The indices of direction 1.
Let the length of direction 1 along the x-axis be X units. The length of the vectors along the y and z axes is 0.
[ X 0 0 ]
⇒ [tex]\left[\begin{array}{ccc}0&0&0\\X'&X'&X'\\\end{array}\right][/tex]
Divide each length by X to convert it into the smallest integer.
⇒ [1 0 0]
And, this is the Miller indices of the direction vector 1.
So, the Miller indices of the direction vector 1 are [ 1 0 0].
Direction 2
The indices of direction 2.
Let the length of direction 2 along the x-axis be X units. The length of the vector along the y and z axes are 0.

Multiply each fractional length by 10 to convert it into the smallest integer.

what is percentage ?In mathematics, a ratio or number expressed as a fraction of 100 is called a percentage. Also occasionally used are the acronyms "pct.," "pct," and "pc." However, the percentage symbol "%" is widely used to represent it. The % quantity is dimensionally empty. Basically, percentages are fractions when the denominator is 100. A percent symbol (%) should be placed next to a number to indicate that it is a percentage. For instance, you score a 75% on a test if you properly answer 75 out of 100 questions (75/100). When calculating percentages, multiply the result by 100 after dividing the amount by the total. By multiplying (value/total) by 100%, the percentage is determined.
given
The value of the percentage decrease
= · 120 - (15% × 120)
= 120 - 15% × 120
= 85 ÷ 100 × 120

You may calculate the percentage drop by simply dividing the lowered value by the original value and multiplying the result by 100.
