After reduction of original size of a document by [tex]30%[/tex]%, the reduction scale is 70% of original size i.e., [tex]70:100=7:10[/tex]

As per the question statement, A photocopier reduces the original size of a document by 30%. We are supposed to find out what is the reduction scale.

Let say the document original size to be [tex]100%[/tex]% and if 30% is reduced by the photocopier, the remaining 70% will be the original size.

Hence reduction scale = [tex]70:100 = 7:10[/tex]

The Four-fifths is equal to ten-sixteenths of a number is x=32/25.

Given the statement is four-fifths is equal to ten-sixteenths of a number.

A mathematical statement is a meaningful component of words that can be  true or false. Simply, they are known as a statement.

Let us assume the given number be x.

According to the given statement,

Four fifths means 4/5.          ......(1)

And ten sixteenths means 10/16.

It is also given that ten sixteenths of a number means is (10/16)x.      .......(2)

Now, we will equate equation (1) and equation (2) according to the given statement is

4/5=(10/16)x

Further, we will cross multiply both sides, we get

4×16=10x×5

64=50x

Now, we will divide both sides by 50, we get

64/50=50x/50

64/50=x

32/25=x

Hence, the number for the given statement "Four fifths is equal to ten sixteenths of a number" is 32/25.

Part (a)

x = the missing value

The set is {81, 54, 77, 68, x}

Add up those values and divide by 5 to compute the mean. Set this equal to the 74.6 stated. Then solve for x like so:

(81+54+77+68+x)/5 = 74.6

(280+x)/5 = 74.6

280+x = 5*74.6

280+x = 373

x = 373-280

x = 93

========================================================

Part (b)

In the previous part, we have n = 5 values and n-1 = 5-1 = 4 of them can be freely selected. The 5th final value is locked in based on what those previous four values are. That 5th value being x mentioned earlier.

This shows that the degrees of freedom is n-1

In other words, one value is determined by the other values in the set.

+(-11) is -11. You're "adding" -11 when in reality you're taking away 11 unless:

the equation looks like: -6+(-11)

the answer would be -17 because you're adding a negative to a negative. Taking away from a negative number is simply moving further down the negative number line, which makes the negative numbers "increase" in value

But if an equation looks like: 6+(-11)

the answer would be -5 since you are taking away 11 from a positive number.

Hope this makes sense and answers your question.

To an algebraic expression, the product of 2.5 and t is 2.5*t=2.5t.

In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.).

Terms comprise expressions.

As said, "The word product" refers to the result of a multiplication.

To find out which two integers are multiplied together, look for the term "AND." The result of adding 2 and 3 is 6

The two numbers being multiplied in this example are 2.5 and an unidentified number, only called t.

The formula is 2.5*t

= 2.5t.

We are at our limit at this point. Since the solution has not been provided, we are unable to write an equation.

The value of h(-2) is 65

A function can be defined as an expression, law , rule of hypothesis that explains or compares the relationship between two variables - the dependent and the independent variable.

Given the function;

h(x) = 2x^4 - x³ + 2x² - 7x + 3

To determine the function, h(-2)

We substitute the value of x as -2 into the function, we have;

h(-2) = 2(-2)^4 - (-2)^3 + 2(-2)^2 - 7(-2) + 3

expand the bracket

h(-2) = 2(16) - 2(-8) - 7(-2) + 3

h(-2) = 32 + 16 + 14 + 3

h(-2)= 65

Thus, the value of h(-2) is 65

After calculating equation we have come to find that the value of y is equal to 0.525 is true

An equation is formed by joining two expressions with the equal sign "=". The two expressions on either side of the equals sign are referred to as the "left-hand side" and "right-hand side" of the equation.

Typically, the right-hand side of an equation is assumed to be zero. This does not reduce generality because we can balance it by subtracting the expression on the right-hand side from the expressions on both sides.

We have given 12y - 1 / 2 = 8y + 8 / 5

lets solve it

⇒ 12y - 1 / 2 = 8y + 8 / 5

⇒ 12y -8y = 8 / 5 + 1 / 2

⇒ 4y = 21/10

⇒ y = 21/40

⇒ y  = 0.525

The car travels 62.5 meters in 5 seconds

The car is driving at 45 kilometres per hour

The first step is to convert kilometres to meters

1 km= 1000 meters

= 45×1000

= 45,000

The next step is to convert hours to seconds

1 hour= 3600 seconds

= 45000/3600

= 12.5

The distance travelled in 5 seconds can be calculated as follows

= 12.5 × 5

Answer:
Velocities

t = 1 :      11 m/s

t = 2 :      27m/s

t = 3:       56.33  m/s

t = a:       6a + 1 + 4/a  m/s

Step-by-step explanation:

s(t) = 6t³ + 1t + 4 where s = displacement in meters and t is time in seconds

s(t)  = v(t). t where v is the velocity in m/s and t is time in seconds
So v = s/t

At time t = 1
s(1) = 6 x 1³ + 1 x 1 + 4  = 6 + 1 + 4 = 11 meters
v(1) = 11/1 = 11 m/s

At time t = 2
s(2) = 6 x 2³ + 1 x 2 + 4 = 6 x 8 + 2 + 4 = 48+ 2 + 4 = 54 m
v(2) = 54 /2 = 27m/s

At time t = 3
s(3) = 6 x 3³ + 1 x 3 + 5 = 6 x 27 + 3 + 4 = 169 m
v(3) = 169/3 = 56.33  m/s

At time t = a
s(a) = 6a³ + 1a + 4 = 6a³ + a + 4
v(a) = s(a)/a = (6a³ + a + 4)/a = 6a + 1 + 4/a m/s

Step-by-step explanation:

The equivalent expression of 14x2 +18x + 5 is 18x + 14x2 + 5, the correct option is D.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

We are given that;

The function  14x2 +18x + 5

Now,

18x + 14x^2 + 5

This expression is equivalent to 14x^2 + 18x + 5, because it has the same terms but in a different order. You can use the commutative property of addition to rearrange the terms in any order without changing the value of the expression. For example:

14x^2 + 18x + 5 = (14x^2 + 5) + (18x)

14x^2 + 18x + 5 = (18x) + (14x^2 + 5)

14x^2 + 18x + 5 = (18x) + (5) + (14x^2)

14x^2 + 18x + 5 = (5) + (18x) + (14x^2)

All of these expressions are equivalent to each other and to the original expression.

Therefore, the equation will be 18x + 14x^2 + 5.

Median means middle. So in order to get that you need to write the numbers in order and then get the middle number. If the amount of numbers are even then take the 2 middle ones and add the together then divide by two.

89, 52, 78, 92, 98, 64 --> 52, 64, 78, 89, 92, 98

Since you have 2 middle numbers, you must take the middle 2 (78 and 89) and add them.
